BASIC PARTS OF A COMPUTER
COMPUTER CASE: is the metal and plastic box that contains the main components of the computer.
Including the:
Motherboard
Central processing unit (CPU)
Power supply
Come in different shapes and sizes:
Desktop case: lies flat on a desk, and the monitor usually sits on top of it.
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.
MONITOR: the monitor works with a video card, located inside the computer case, to display images and text on the screen.
Newer monitors usually have:
LCD (liquid crystal display) or LED (light-emitting diode) displays. These can be made very thin, and they are often called flat-panel displays.
CRT (cathode ray tube) displays. CRT monitors are much larger and heavier, and they take up more desk space.
KEYBOARD: The keyboard is one of the main ways to communicate with a computer(most are very similar).
Come in different shapes and sizes:
Ergonomic
Wireless
MOUSE: it lets you point to objects on the screen, click on them, and move them.
There are two main types:
OPTICAL MOUSE: the optical mouse uses an electronic eye to detect movement and is easier to clean.
MECHANICAL MOUSE: the mechanical mouse uses a rolling ball to detect movement and requires regular cleaning to work properly.
Alternatives mouse: There are other devices that can do the same thing as a mouse. Many people find them easier to use.
Trackball: A trackball has a ball that can rotate freely. Instead of moving the device like a mouse, you can roll the ball with your thumb to move the pointer.
Touchpad: A touchpad is a touch-sensitive pad that lets you control the pointer by making a drawing motion with your finger. Touchpads are common on laptop computers.
