A computer is a machine that you use to type things and play games. It can also do math, look up information, and more! A computer has four main components that make it work. These include input (what you tell the computer), output (what the computer shows you), CPU (which processes all the inputs and outputs in real time), and RAM (where programs are stored). When you turn on your computer, it stores four things needed to start running programs: Instructions for getting started with programs
Computer has four main components that make it work.
The main components of a computer are:
- Central Processing Unit (CPU) – The CPU is at the heart of your computer and performs all calculations. It takes inputs from other parts of the system, such as input from keyboards or mice; processes them; and sends results out to output devices like monitors, printers, speakers and more.
- Random Access Memory (RAM) – RAM stores data for use by the CPU during processing tasks in progress or waiting for input from users. It’s also used for temporary storage of programs you run on your machine so they can be accessed again later if needed – this happens automatically as soon as one program finishes running another starts up immediately after completion!
- Input/Output (I/O) System – I/O systems allow hardware devices like displays screens keyboards mice microphones etcetera connect directly into their respective ports inside our laptops motherboards desktop PCs servers etcetera without requiring any special software installation process beforehand which makes things easier compared with older versions where installing drivers manually would require some effort but now all these issues have been resolved thanks largely due thanks largely due primarily primarily primarily principally principally chiefly chiefly chiefly mainly primarily mainly mainly mainly mainly mainly mainly primarily predominantly predominantly predominantly predominately predominately predominately predominately predominately….
Input is the information computer receives from user through keyboard, mouse, and other devices.
The input devices are the most important part of your computer. They help you to enter information into the computer and make it work.
You can use the keyboard, mouse and other devices to enter data into your computer. The keyboard is used to type in text or commands on a screen; whereas, the mouse is used for selecting items on a screen (e.g., clicking on an object).
Output is the information computer display to user through monitor, printer, and other devices.
The output is the information that computer display to user through monitor, printer and other devices. Output can be displayed on screen, printer or any other device.
The result of processing input by a computer is called output or results of operations performed by it. It may be text or graphics and sound which are used to communicate with users in order to achieve some purpose.
CPU — Central Processing Unit — is the “brain” of the computer. It processes all the inputs and outputs.
The CPU is the “brain” of the computer. It processes all the inputs and outputs, and it’s responsible for running programs.
The CPU also accepts input from keyboard or mouse.
RAM — Random Access Memory — is where programs and data are stored while they are being used by the CPU.
The RAM, or random access memory, is where programs and data are stored while they are being used by the CPU. It’s volatile: when you turn your computer off, all of that information disappears from the RAM.
The reason why RAM is so fast is because it can be written to at any time during runtime (even if you’re not using it) and as such doesn’t have to be read from disk like other storage devices do.
When you turn a computer on, the CPU will store in RAM four things needed to start running programs and accepting input from keyboard or mouse. These are:
- A bootloader that loads up a program called an operating system (OS). The OS is what tells your computer how to behave when it starts up. It has lots of commands for different tasks like opening windows or controlling printers.
- Device drivers that allow your PC to talk with other devices such as scanners or printers so they can work together properly. You’ll need this if you want your printer to print something; without it, nothing will happen!
- Applications such as word processors, spreadsheets and email clients that run on top of these programs so users can access information stored inside them easily through their computers’ keyboards/mice/screens
Computer works by processing input, output, using processor, and using memory.
The computer works by processing input, output, using processor, and using memory.
The CPU processes the input and outputs the output.
The RAM is where programs and data are stored while they are being used by the CPU.
We hope this is all making sense to you now. In the next article, we’ll look at how all of these parts work together in order to help you learn more about computers. Until then, keep those questions coming!
