Common Computer Hardware Terminology
When it comes to repairing, building or just understanding computer hardware, it pays to know the terminology. Computers have so many different parts it can often be difficult to keep track of the terminology. Here is a list of some of the most common hardware components included in desktop and laptop computers.
AC Adapter – This is the cable and transformer that converts the AC power from a wall outlet to the DC power a laptop requires. It is also referred to as a power cord or power brick.
Battery – The battery stores and supplies portable power for a laptop or notebook.
DC Jack – The DC jack is the input jack where the AC adapter connects to the laptop. If this jack fails, the adapter can no longer supply power to the device.
Fans – Almost all types of computers have one or more cooling fans to deal with the heat generated by other components.
Hard drive – The hard drive is the large storage device that stores the operating system and all of the necessary files and folders that are necessary for the computer to operate.
Inverter – The inverter supplies the higher AC voltage required for the LCD backlight.
Keyboard – The keyboard is the input device for typing text and other characters into the computer. Laptop keyboards are integrated into the machine, but can often be replaced if damaged or malfunctioning.
LCD Display – The LCD display is the flat-panel display included with most notebooks and laptops, and it displays the information and interface of the computer so the user can view it.
Memory (RAM) – Memory usually refers to the RAM (Random Access Memory) which comes in the form of computer chips which are installed into slots. The RAM stores temporary information about programs and documents that are currently open or running. RAM cannot store information while it is powered down, unlike hard drives.
Motherboard – The motherboard is the large computer board that connects all of the devices that make a computer or laptop function. It handles the routing of power and information between all devices. Many motherboards even contain sound chips and other components directly on board.
AC Adapter – This is the cable and transformer that converts the AC power from a wall outlet to the DC power a laptop requires. It is also referred to as a power cord or power brick.
