Older monitors use CRT (cathode ray tube) displays. CRT monitors are much larger and heavier, and they take up more desk space.
what is a mouse
The mouse is another important tool for communicating with computers. Commonly known as a pointing device, it lets you point to objects on the screen, click on them, and move them

basic parts of computer
The basic parts of a desktop computer are the computer case, monitor, keyboard, mouse, and power cord. Each part plays an important role whenever you use a computer.
back of computer case
Computer cases come in different shapes and sizes. A desktop case lies flat on a desk, and the monitor usually sits on top of it. A tower case is tall and sits next to the monitor or on the floor. All-in-one computers come with the internal components built into the monitor, which eliminates the need for a separate case.
Microphones: A microphone is a type of input device, or a device that receives information from a user.
network card.
The network card allows your computer to communicate over a network and access the Internet.
setting up a computer
So you have a new computer and you're ready to set it up. This may seem like an overwhelming and complicated task, but it's actually a lot easier than you might think! Most computers are set up in a similar way, so it doesn't matter what brand of computer you have.
If you're setting up a new computer that's still in the box, you'll probably find a how-to guide that includes step-by-step details. Even if it didn't include instructions, you can still set up the computer in a few easy steps. We'll take you through the different steps needed to set up a typical computer.
Watch the video below to learn how to set up a desktop computer.
If you have a laptop, setup should be easy: Just open it and press the power button. If the battery isn't charged, you'll need to plug in the AC adapter. You can continue using the laptop while it charges.
If your laptop has any peripherals, like external speakers, you may want to read the instructions below. Laptops and desktops generally use the same types of connections, so the same steps will still apply.Unpack the monitor and computer case from the box. Remove any plastic covering or protective tape. Place the monitor and computer case on a desk or work area. Locate the monitor cable. There are several types of monitor cables, so the one for your computer may not look like the one in the image below.
If you're having trouble finding your monitor cable, refer to the instruction manual for your computer. (If you have an all-in-one computer that's built into the monitor, you can skip to Step 4).
Step 3
Connect one end of the cable to the monitor port on the back of the computer case and the other end to the monitor.
