Whether we use a computer, laptop, smartphone or tablet these days, all these devices have one thing in common: they all run on some kind of operating system (OS). But what exactly is an operating system, and what does it do? Definition of Operating System Operating system is a type of system software and it is pre-installed in the computer. Operating system manages every function of the computer. When the computer starts, the operating system checks whether all the parts of the computer are connected or not. The operating system allows us to create files and folders on the computer. If the operating system does not support any file, then we cannot work on that file. The operating system also checks which software you are installing on the computer. If the software is not compatible with the operating system, then you cannot install that software. There are many type of operating systems available nowadays, the most popular of which are – Windows 10, Windows 11, macOS, Linux. Main func

Like every machine, a computer is also made up of many parts and the parts of a computer are called computer hardware. These parts are necessary for the computer to work properly. What is Computer Hardware? Any part of the computer that you can touch with your body is called computer hardware. It is like the body of the computer. Some important parts of computer hardware are as follows: CPU The CPU is called the brain of the computer and its job is to perform calculations and process instructions from programs. When you type something on the computer or click with the mouse, the CPU processes those actions. Not all CPUs have the same speed. The speed and power of the CPU affect how quickly your computer can perform tasks like opening apps, playing games, or browsing the Internet. RAM RAM is a hardware of the computer in which the stored data remains for some time and hence it is also called volatile memory.

A computer monitor is an output device and it looks like a TV, but instead of watching shows or movies, we use it to see what is happening on our computer. If we are typing a document, playing games, watching a movie, the monitor shows all of it. Parts of a Monitor 1. Screen A monitor's screen is like a glass through which the computer shows the activity that we are doing on the computer. Screen comes in different sizes and they are measured in inches. 2. Ports Every monitor has at least two ports - one to connect the power cable to switch board, another to connect the monitor to CPU. Some monitors may have more ports to connect with other devices. 3. Buttons All the monitors have buttons to adjust the display settings like brightness, contrast, color mode etc. If a monitor has speakers, you will also find buttons to adjust volume level. Types of Monitor 1. CRT (Cathode Ray Tube) monitors The first computers had CRTs. They were like a big, boxy TV or computer screen. They also use

What is Artificial Intelligence? Artificial Intelligence, shortly termed as AI, is a field in computer science that involves creating computer machines and applications that are capable of performing tasks that would normally require human intelligence. These tasks include learning from experience, problem-solving, understanding natural language, and recognizing patterns. Understanding AI At its core, AI attempts to replicate human intelligence in machines. Intelligence is the ability to acquire and apply knowledge, adapt to new situations, solve problems, and learn from experiences. AI systems are designed to mimic these cognitive functions, enabling them to perform tasks ranging from simple to highly complex. AI can be broadly classified into two main types: narrow AI (or weak AI) and general AI (or strong AI). Narrow AI (Weak AI): Narrow AI is designed for specific tasks and excels in those areas, but it lacks the versatility of human intelligence. A common example is voice assistan

Imagine that your computer is like a super smart friend that does all kinds of tasks for you. It runs on a special system called Windows, which is like its brain. Just like people sometimes get a little sick, computers can malfunction or have problems. So, imagine you are playing a game or doing your homework on your computer, and suddenly, it stops working and shows you a big blue screen with a sad face. That blue screen is BSoD. It's like when your computer says, "Wait, something really went wrong, and I can't figure it out." That blue screen is like a signal telling you, "Hey, I'm facing a problem that's too big for me to deal with on my own, so I need to stop and get some help." " It may show some strange numbers and words on the screen – they are like secret messages for computer experts. These messages help them understand what caused the computer to get confused. Just like when you feel sick, you might need to go to the doctor to find out

Imagine your computer as a complex machine with many different parts that need to work together seamlessly. The computer motherboard, also called the mainboard or logic board, plays an important role in making this happen. What is a Computer Motherboard Think of the computer motherboard as the central nervous system of the computer. It is a flat, rectangular circuit board that provides the basis for all the major components of a computer to connect and communicate. Just like nerves connect different parts of your body to your brain, the motherboard connects the different components of the computer to the main processing unit, which is like the brain of the computer. Functions of Computer Motherboard Component mounting A motherboard has slots, sockets, and connectors that are designed to accommodate critical components such as the CPU (central processing unit), memory modules, graphics cards, storage drives , and more. It's like a giant puzzle board where each piece has its own des
