10 Influential Women in Computer Science and Their Contributions
Computer science has shaped nearly every aspect of modern life, from how we communicate and work to how decisions are made by machines. While the field is often portrayed as male-dominated, many of its most important breakthroughs were driven by women whose ideas defined entire disciplines, from programming languages and operating systems to cryptography and artificial intelligence. This article highlights ten influential women in computer science whose contributions laid the foundations for today’s digital world and continue to influence how technology is built, studied, and governed. By examining their work, we gain a clearer understanding of how computer science evolved and why recognizing these contributions matters for the future of innovation.
10 Influential women in computer science and what they contributed
1. Ada Lovelace (1815–1852)
Often regarded as the world’s first computer programmer, Ada Lovelace worked in the mid-19th century on Charles Babbage’s Analytical Engine, a mechanical general-purpose computer that was never fully built. Her most significant contribution was recognizing that such a machine could do more than calculate numbers. In her notes, she described how the engine could manipulate symbols according to rules, an idea that directly anticipates modern software.
Lovelace also wrote what is widely considered the first algorithm intended to be processed by a machine, outlining steps for computing Bernoulli numbers. This went beyond theoretical speculation and demonstrated how a programmable device could follow structured instructions. Her insight that computation could extend to music, graphics, and other non-numerical domains set the conceptual groundwork for modern computing, making her influence foundational rather than merely historical.
2. Grace Hopper (1906–1992)
Grace Hopper played a central role in transforming computers from specialized scientific machines into practical tools that businesses and governments could use. As a mathematician and U.S. Navy rear admiral, she worked on some of the earliest electronic computers, including the Harvard Mark I, where she helped develop foundational programming techniques at a time when software as a concept barely existed.
Her most lasting contribution was championing the idea that computers should be programmed using human-readable languages rather than raw machine code. Hopper led the development of the first compiler, which translated written instructions into machine language, and later helped create COBOL, one of the earliest high-level programming languages. COBOL’s influence persists today, particularly in banking, government, and large enterprise systems.
Hopper also popularized the term “debugging” after a moth was famously removed from a computer relay, but her real legacy lies in making programming more accessible and scalable. By bridging the gap between human logic and machine execution, she helped set the direction for modern software development as an engineering discipline rather than a purely mathematical exercise.
3. Margaret Hamilton (1936–present)
Margaret Hamilton fundamentally changed how software is treated in large, mission-critical systems. As the director of the Software Engineering Division at MIT’s Instrumentation Laboratory, she led the team responsible for the onboard flight software used in NASA’s Apollo missions, including the historic Apollo 11 moon landing.
During Apollo 11’s descent, unexpected computer overloads triggered alarms moments before landing. Hamilton’s software design prioritized critical tasks and safely discarded lower-priority processes, allowing the mission to continue. This incident became one of the clearest demonstrations that software reliability could be as important as hardware integrity, especially in real-time systems where failure was not an option.
Hamilton is also credited with popularizing the term “software engineering,” arguing that software development should be treated as a rigorous engineering discipline rather than an informal or secondary task. Her work laid the foundation for modern concepts such as fault tolerance, priority scheduling, and robust system design, all of which remain central to aerospace, defense, and safety-critical computing today.
4. Barbara Liskov (1939–present)
Barbara Liskov’s work reshaped how programmers design reliable and scalable software systems. She is best known for formulating the Liskov Substitution Principle (LSP), a core concept in object-oriented programming that defines how subclasses should behave in relation to their parent classes. Today, LSP is considered one of the fundamental rules for writing maintainable and predictable code.
Beyond theory, Liskov led the development of CLU, an influential programming language that introduced ideas such as abstract data types, encapsulation, and exception handling. These concepts are now standard features in modern languages like Java, Python, and C++, even if programmers are unaware of their origins. CLU helped formalize the idea that software components should expose clear interfaces while hiding internal complexity.
Liskov’s research also extended into distributed systems, where she worked on fault tolerance and data consistency, long before cloud computing made these challenges mainstream. Her contributions bridged academic theory and real-world practice, influencing how large software systems are built, reasoned about, and trusted in both commercial and critical applications.
5. Frances Allen (1932–2020)
Frances Allen was a trailblazer in compiler optimization, a field that determines how efficiently high-level code is transformed into machine-executable instructions. Working at IBM for decades, she helped establish many of the theoretical and practical foundations that modern compilers rely on to improve performance, reduce memory usage, and enable parallel execution.
Allen’s research introduced key concepts such as control-flow analysis and data-flow analysis, which allow compilers to understand how programs behave as they run. These techniques made it possible to automatically optimize code without changing its intended behavior, a critical step in scaling software for increasingly powerful and complex hardware architectures.
In 2006, Allen became the first woman to receive the Turing Award, often described as the Nobel Prize of computer science. Her work remains deeply embedded in modern computing, from high-performance scientific simulations to everyday applications, even though it largely operates behind the scenes. By making programs faster and more reliable at a fundamental level, Allen helped shape the efficiency of modern computing itself.
6. Radia Perlman (1951–present)
Radia Perlman is often referred to as the “mother of the internet” for her foundational work in computer networking. Her most significant contribution is the Spanning Tree Protocol (STP), which allows Ethernet networks to automatically prevent loops while maintaining reliable connectivity. STP became a core standard in network bridges and switches and remains fundamental to how local area networks operate today.
Before Perlman’s work, large networks were difficult to scale and prone to failure due to broadcast storms and routing loops. STP introduced a mathematically sound way for networks to self-organize, enabling redundancy without instability. This made modern enterprise networks, data centers, and early internet infrastructure both scalable and resilient.
Beyond STP, Perlman has contributed extensively to network security, routing, and protocol design, consistently emphasizing simplicity, correctness, and robustness. Her work shaped the invisible infrastructure that allows devices around the world to communicate reliably, making global networking practical long before cloud computing and always-on connectivity became the norm.
7. Jean Bartik (1924–2011)
Jean Bartik was one of the original programmers of ENIAC, the first general-purpose electronic digital computer. At a time when programming was not yet recognized as a distinct discipline, Bartik and her colleagues developed methods for configuring ENIAC to solve complex mathematical problems, including ballistic trajectory calculations for the U.S. military.
Unlike modern programming, ENIAC did not use stored programs. Bartik’s work involved physically rewiring the machine, setting switches, and designing logical workflows from scratch. This required deep understanding of both the hardware and the mathematics behind each problem, effectively inventing programming practices without precedents, tools, or documentation.
For decades, Bartik’s contributions were overlooked as attention focused on ENIAC’s hardware designers. Later historical reassessment corrected this narrative, recognizing that ENIAC’s success depended as much on its programmers as its engineers. Bartik’s work helped establish programming as a legitimate and essential part of computer science, laying groundwork for the profession that followed.
8. Shafi Goldwasser (1958–present)
Shafi Goldwasser is one of the most influential figures in modern cryptography, helping to transform it from a collection of ad hoc techniques into a rigorous scientific discipline. Her work focuses on the mathematical foundations of secure communication, addressing how information can be protected even in the presence of powerful adversaries.
Goldwasser is best known for co-inventing zero-knowledge proofs, a breakthrough concept that allows one party to prove a statement is true without revealing any additional information. This idea reshaped cryptographic theory and has since found practical applications in privacy-preserving authentication, secure transactions, and modern blockchain systems.
She also made foundational contributions to computational complexity and encryption theory, helping define what it actually means for a system to be “secure.” Goldwasser’s research continues to influence how governments, financial institutions, and technology companies think about privacy and trust in a digital world where data security is increasingly critical.
9. Karen Spärck Jones (1935–2007)
Karen Spärck Jones played a foundational role in information retrieval, the field that underpins modern search engines. Her most influential contribution was the development of inverse document frequency (IDF), a statistical concept that helps determine how important a word is within a collection of documents. IDF later became a core component of the TF-IDF weighting scheme, still widely used in search, text mining, and natural language processing.
Before her work, early information systems struggled to distinguish meaningful terms from common but uninformative ones. Spärck Jones’s insight made it possible for computers to rank documents based on relevance rather than simple keyword matching, dramatically improving search accuracy. This shift laid the groundwork for modern web search long before the rise of large-scale commercial search engines.
She was also a strong advocate for natural language processing and interdisciplinary research, arguing that language understanding was central to human-computer interaction. Spärck Jones’s ideas continue to influence how information is indexed, retrieved, and ranked, making her contributions essential to how users find and access information online today.
10. Fei-Fei Li (1976–present)
Fei-Fei Li has been a driving force behind the modern rise of artificial intelligence, particularly in the field of computer vision. She is best known for leading the creation of ImageNet, a large-scale visual database that provided millions of labeled images for training machine-learning models. ImageNet became the catalyst for major breakthroughs in deep learning by enabling algorithms to learn visual patterns at an unprecedented scale.
The annual ImageNet Large Scale Visual Recognition Challenge demonstrated dramatic improvements in image classification accuracy, marking a turning point for neural networks and accelerating AI adoption across industries. Technologies such as facial recognition, autonomous driving, medical imaging, and visual search all trace part of their rapid progress back to the availability of ImageNet and the research ecosystem it enabled.
Beyond technical contributions, Fei-Fei Li has been a prominent advocate for human-centered and ethical AI. She has emphasized the importance of aligning artificial intelligence with societal values, transparency, and fairness. Her work connects cutting-edge research with broader questions about how AI should be developed and deployed, making her influence as much philosophical as it is technical.
Conclusion: why these women matter in computer science
Taken together, the work of these ten women shows that computer science did not advance through a single discipline or generation, but through sustained innovation across theory, hardware, software, and human-centered design. From Ada Lovelace’s early vision of programmable machines to Fei-Fei Li’s role in shaping modern artificial intelligence, each contribution addressed a fundamental problem that continues to define how computing systems operate today.
What also stands out is the durability of their ideas. Compiler optimizations, object-oriented design principles, networking protocols, cryptographic proofs, and search algorithms are not historical footnotes; they remain embedded in everyday technologies used by billions of people. In many cases, these women established standards and frameworks that still guide research and engineering decisions decades later.
Recognizing these contributions is not simply about correcting the historical record. It provides a clearer picture of how progress in computer science actually happens: through diverse perspectives, rigorous thinking, and long-term impact rather than short-term trends. As the field continues to evolve, the foundations laid by these pioneers remain essential to understanding both where modern computing came from and where it is headed next.

What is Better, High Sensitivity or Low Sensitivity in Gaming?
Today we’re going to get to the bottom of what DPI is and how it affects gaming performance. We’ll also sort out whether low or high DPI is better for different types of games, and how to change DPI settings in Windows 11.
Mouse sensitivity directly affects aiming precision, camera control, and reaction speed in PC gaming. While many players adjust sensitivity without fully understanding it, the key technical factor behind mouse responsiveness is DPI.
Choosing the right setting can improve consistency and comfort, while the wrong setting can lead to overcorrection, missed shots, and unstable tracking.
What is DPI on a mouse?
DPI stands for dots per inch. In the context of a computer mouse, it measures how many pixels the cursor moves on screen for every inch you physically move the mouse on your desk. At 400 DPI, moving your mouse one inch moves the cursor 400 pixels, while at 1600 DPI, moving your mouse one inch moves the cursor 1600 pixels.
So, a higher DPI makes the mouse more sensitive. Small physical movements result in large cursor movements. A lower DPI makes the mouse less sensitive, requiring larger hand movements to move the cursor the same distance.
It’s crucial to distinguish DPI from in-game sensitivity. DPI is a hardware-level setting controlled by the mouse itself. In-game sensitivity is a software multiplier applied inside a specific game. Your overall responsiveness is determined by the combination of both.
Most modern gaming mice allow adjustable DPI levels, either through dedicated software or via a physical DPI button that cycles through preset values. Some mice allow precise numerical adjustments, while others offer fixed increments.
How does DPI affect gaming?
DPI influences how quickly and how accurately you can move your crosshair or camera in a game. Its impact can be seen in several areas.
1. Aiming precision. Lower DPI generally allows finer control when making small adjustments. This can help with long-range aiming, recoil control, and smooth target tracking. Higher DPI can make small adjustments more difficult if sensitivity is too high, since tiny hand movements translate into larger on-screen motion.
Turning speed. Higher DPI allows rapid camera rotation with minimal physical movement. This can be useful in fast-paced games where quick directional changes are frequent. Lower DPI requires larger arm movement for the same turn, which can feel slower but often results in more controlled motion.
2. Consistency and muscle memory. Consistency is critical in competitive gaming. Once you adapt to a specific DPI and in-game sensitivity combination, your brain builds muscle memory. Frequent changes can temporarily reduce accuracy while your coordination adjusts.
3. Physical setup. Low DPI players often use larger mousepads and rely on arm movement. High DPI players typically use wrist movement and smaller desk space. Your physical setup may influence which setting feels more natural.
In practical terms, DPI affects control, speed, comfort, and consistency. It does not directly improve skill, but it can support better performance when properly configured.
Low DPI vs high DPI, which is better for gaming?
There is no single DPI setting that is best for everyone. The optimal choice depends on the type of game and your personal preference.
Low DPI settings, commonly between 400 and 800 DPI, are widely used in competitive first-person shooters. Low DPI offers greater precision for fine aiming adjustments, allowing smoother and more deliberate crosshair placement. It also supports more controlled recoil management and steadier target tracking, particularly at longer ranges. However, lower DPI requires more desk space because it involves larger physical mouse movements, often using the entire arm rather than just the wrist. It may also feel slow in fast camera scenarios where rapid turning or quick directional changes are necessary. Lower DPI combined with moderate in-game sensitivity often results in lower overall effective sensitivity, which many competitive players prefer for accuracy.
High DPI settings, such as 1600 DPI or higher, increase overall responsiveness by allowing the cursor or crosshair to move farther with smaller physical movements. This enables faster camera rotation and requires less physical effort, which can be convenient for players with limited desk space or those who prefer wrist-based movement. However, high DPI can make small aiming adjustments harder to control, especially in precision-focused games. If sensitivity is set too high, it may also lead to overcorrection and unstable tracking. Still wondering if higher DPI is better? High DPI is not inherently superior; it simply changes how responsive the mouse feels. Higher DPI is not automatically better for gaming, and extremely high DPI values can make aiming inconsistent if they are not balanced with appropriately reduced in-game sensitivity.
What matters most is whether you can aim consistently and comfortably. Many players experiment before settling on a stable configuration that supports reliable performance. Remember, the goal is controlled responsiveness, not maximum sensitivity. We recommend trying various settings, as having the wrong DPI can actually limit your ability to succeed in certain games.
Medium DPI settings: the middle way?
A mid-range DPI setting, typically between 800 and 1600, delivers a practical mix of responsiveness and precision. Many gamers settle on 800 or 1600 DPI because these values perform reliably across a wide range of titles.
This range works especially well for RPGs, MOBAs, and strategy-based games, where steady cursor control is just as important as the ability to react quickly. Titles such as League of Legends and World of Warcraft feel natural and manageable within this DPI window.
If you regularly move between different genres, medium DPI is a convenient choice. It reduces the need to constantly adjust your mouse configuration every time you launch a new game.
On a 1440p display, 800 DPI typically offers smooth tracking when paired with standard in-game sensitivity settings. The cursor speed remains comfortable for both gameplay and everyday tasks. For higher-resolution screens, 1200 DPI can provide a slightly faster feel while still maintaining solid control.
How to Change the DPI on Windows 11
Windows 11 does not directly change your mouse’s hardware DPI, but it allows you to adjust pointer speed and related sensitivity settings at the operating system level. To adjust mouse sensitivity in Windows 11:
* Open Settings.
* Select Bluetooth & devices.
* Click Mouse.
* Adjust the Mouse pointer speed slider.
For additional options:
* Click Additional mouse settings.
* Open Pointer Options.
* Disable Enhance pointer precision for more consistent tracking.
Many gamers disable pointer acceleration to maintain predictable movement. If your mouse supports adjustable DPI, the most accurate way to change DPI is through the physical DPI button or the manufacturer’s configuration software.
Remember to only adjust one variable at a time. Changing DPI, Windows sensitivity, and in-game sensitivity simultaneously can make it difficult to determine what is improving or reducing performance.
High, low or in-between sensitivity?
High sensitivity and low sensitivity each offer advantages, but neither is universally better. DPI determines how responsive your mouse is, while in-game sensitivity modifies that response. Lower DPI often supports precision and controlled aiming, particularly in competitive shooters. Higher DPI enables faster movement with less physical effort. The most effective approach is to choose a setting that feels natural, allows consistent aim, and supports your specific game type. Stability and muscle memory matter more than chasing extreme sensitivity values.
For players looking to get the most out of their sensitivity settings, hardware also plays an important role. High refresh rate displays, responsive trackpads and sensors, and powerful GPUs contribute to smoother aiming and stable frame rates. Acer gaming laptops like the Predator Helios 16 AI deliver AI-driven performance and OLED visual clarity for both gaming and productivity, while the Acer Nitro V 16 AI AMD offers AI-powered gaming performance with smooth visuals and strong connectivity for essential gamers.
FAQs
What Is DPI on a Mouse?
DPI, or dots per inch, measures how sensitive a mouse is. Higher DPI means the cursor moves farther with less physical movement.
Is Higher DPI Better for Gaming?
Not necessarily. Very high DPI can make aiming harder to control. The best setting is the one that feels consistent and comfortable.
Low DPI vs High DPI: Which Should I Use?
Low DPI is often better for precision and control. High DPI allows faster movement with less effort. The right choice depends on your game and playstyle.
What DPI Do Most FPS Players Use?
Many competitive FPS players use lower DPI settings, commonly around 400 to 800 DPI, combined with adjusted in-game sensitivity.
How to Lower Mouse DPI?
Use your mouse’s DPI button or adjust the setting in the manufacturer’s software. You can also lower sensitivity inside your game.
How Do I Change DPI on Windows 11?
Go to Settings > Bluetooth & Devices > Mouse and adjust pointer speed. Disable “Enhance pointer precision” for more consistent tracking.

How to Check and Limit Data Usage on Windows 11
Keeping track of your internet data usage is more important than many people realize. Whether you are on a capped home broadband plan, using a mobile hotspot, or trying to diagnose slow speeds and unexpected overages, knowing exactly how much data your PC is consuming can help you avoid surprise charges and performance issues. Windows 11 includes built-in tools that let you monitor network usage without installing third-party software.
This guide explains how to check internet data usage on Windows 11, what the numbers actually mean, and how to use that information to make smarter decisions about your network settings and connected apps. By the end, you will know where to find Windows 11 data usage statistics, how to reset or customize tracking periods, and when it makes sense to take additional steps to limit background data consumption.
What counts as internet data usage in Windows 11
When Windows 11 tracks internet data usage, it measures how much data is sent and received by your device over a specific network connection. This includes both visible activity, like streaming videos or downloading files, and background activity that happens without direct user input.
* Web browsing and streaming: Loading websites, watching videos, and listening to music all consume data, with video streaming using the most by far.
* App downloads and updates: Installing apps from the Microsoft Store, downloading game updates, or updating third-party software can quickly add up, especially on fresh installs or new PCs.
* Windows updates: System updates, security patches, and feature updates are included in your data usage total unless restricted by a metered connection.
* Background apps and services: Cloud sync tools, messaging apps, telemetry, and system services may use data even when you are not actively using your PC.
* Connected devices and hotspots: If your Windows 11 PC is connected through a mobile hotspot or tethered connection, all activity on that network is counted toward your usage.
It is also important to note that Windows tracks data per network, not globally. This means your data usage on Wi-Fi, Ethernet, and mobile connections is recorded separately, which is useful if you switch between home internet and capped connections.
How to check internet data usage on Windows 11
Windows 11 includes a built-in data usage tracker that shows how much internet data your device has used over time, broken down by network and app. You do not need any third-party software to access this information.
Step 1: Open the Settings app
Click the Start button, then select Settings. You can also press Windows key + I to open Settings directly.
Step 2: Go to Network & internet
In the left-hand menu, click Network & internet. This section contains all network-related settings, including Wi-Fi, Ethernet, and data usage tracking.
Step 3: Select Data usage
In Network & internet, look to the top-right corner of the window and click Data usage. You can also see your total internet usage in this area, but this figure only reflects data usage from the last 30 days. Clicking Data usage opens the full data usage dashboard.
Step 4: Choose the correct network
At the top of the Data usage page, use the drop-down menu to select the network you want to check. Windows 11 tracks data usage separately for different connection types, so make sure the selected network matches how you are connected to the internet.
Step 5: Review total and app-level usage
On the Data usage screen, you will see:
* Total data usage for the selected network
* A breakdown by app, ranked by how much data each app has used
Above the app list, you can change the time range to view usage over the last 24 hours, 7 days, or 30 days. This helps identify short-term spikes in data use as well as apps that consistently consume large amounts of bandwidth.
How to set a data limit in Windows 11
If you are on a capped internet plan or regularly use a mobile hotspot, setting a data limit in Windows 11 can help prevent unexpected overages. When a data limit is enabled, Windows tracks your usage against that cap and provides warnings as you approach it.
Step 1: Open Data usage
Go to Settings > Network & internet, then click Data usage in the top-right corner.
Step 2: Select the correct network
Use the drop-down menu at the top of the page to choose the network you want to limit. Data limits are applied per network, so make sure you select the Wi-Fi, Ethernet, or mobile connection you want to control.
Step 3: Set a data limit
Click Enter limit under the Data usage section. In the window that appears, choose:
* The limit type (monthly, one-time, or unlimited)
* The data amount, using MB or GB (Windows 11 does not currently offer a TB option)
* The reset date, if you are using a monthly limit
Click Save to apply the data limit.
If your plan includes very high allowances, you can manually convert terabytes to gigabytes. For example, a 1 TB limit would be entered as 1024 GB.
Step 4: Monitor usage and warnings
Once a data limit is set, Windows 11 will track your usage against it. You will see warnings as you approach the limit, making it easier to adjust your activity or reduce background data usage before hitting the cap.
Note: Reaching your data limit in Windows 11 does not automatically cut off your internet connection. Instead, Windows will display warnings and notifications to let you know the limit has been reached. Your device will continue to connect to the internet unless your internet service provider enforces its own restrictions or charges for exceeding your plan. This makes the data limit a monitoring and warning tool rather than a hard cap.
Why checking internet data usage on Windows 11 matters
Monitoring your internet data usage in Windows 11 helps you stay in control of your connection, especially if you are on a capped plan or regularly switch between different networks. Even on unlimited plans, tracking usage can reveal performance issues or apps that consume more bandwidth than expected.
Common reasons to check data usage include:
* Avoiding data overages: If your internet service provider enforces monthly limits, monitoring usage helps prevent extra charges or throttling.
* Identifying bandwidth-heavy apps: Browsers, streaming services, cloud storage tools, and game launchers can consume large amounts of data, sometimes in the background.
* Troubleshooting slow internet speeds: Unexpected spikes in data usage can explain sudden slowdowns, especially on shared or metered connections.
* Managing mobile hotspots: When using tethering or hotspot data, tracking usage helps avoid exhausting limited data allowances.
* Understanding how shared computers are used: On family PCs, data usage can reveal whether time was spent on schoolwork or on bandwidth-heavy activities like gaming. Large spikes tied to game platforms may indicate downloads or online play that happened while you were away.
* Understanding background activity: Windows updates, app updates, and system services may use data even when your PC appears idle.
This context makes it easier to decide whether to set data limits, restrict background apps, or change how your PC connects to the internet.
Final thoughts
Windows 11 makes it easy to check internet data usage without relying on third-party tools. By understanding where to find usage statistics, how data is tracked per network, and how to set a data limit, you gain better visibility into how your PC uses the internet day to day.
Whether you are trying to avoid data overages, troubleshoot slow connections, manage shared computers, or keep an eye on background activity, Windows 11’s built-in data usage tools give you the information you need to make informed decisions. A quick check now and then can help prevent surprises and keep your internet usage under control.
FAQ
Does Windows 11 show internet data usage in real time?
No. Windows 11 updates data usage statistics periodically, not in real time. While the numbers are generally accurate, there may be a short delay before recent activity appears in the Data usage dashboard.
Why does Windows 11 only show data usage for the last 30 days?
By default, Windows 11 tracks internet data usage over a rolling 30-day period. This timeframe cannot be extended automatically, but you can reset the tracking period manually or align it with your billing cycle by setting a data limit.
Can Windows 11 track data usage for all Wi-Fi networks combined?
No. Windows 11 tracks data usage per network, not across all connections. Each Wi-Fi network, Ethernet connection, or mobile network has its own usage history and data limit settings.
Does setting a data limit stop my internet connection?
No. Setting a data limit in Windows 11 does not block internet access. It only provides warnings and notifications when you approach or exceed the limit. Any speed throttling or service interruption is controlled by your internet service provider, not Windows.
Why is my data usage so high even when I am not using my PC?
High data usage can be caused by background activity such as Windows updates, app updates, cloud sync services, game launcher downloads, or other apps running in the background. Checking the app-level breakdown in Data usage can help identify the cause.
Can I reset data usage statistics in Windows 11?
Yes. You can reset data usage for a specific network by going to Settings > Network & internet > Data usage, selecting the network, and choosing the reset option. This clears the usage history and starts a new tracking period.
Is Windows 11 data usage accurate compared to my ISP?
Windows 11 provides a good estimate, but it may not exactly match your ISP’s numbers. Internet providers measure data at the network level, while Windows tracks usage at the device level, which can result in small differences.
