YOUR NAME
1. Hard Drive - A hard drive is a non-volatile memory hardware device that permanently stores and retrieves data on a computer. It’s a secondary storage device that consists of one or more platters to which data is written using a magnetic head, all inside of an air-sealed casing
2. Fan – A hardware device that keeps the overall computer or a computer device cool by circulating air to or from the computer or component. If this fan reaches a pre-set temperature, the computer will shut down. This is called a "thermal check," and mainframes, servers and personal computers all have this protective feature built in.
3. Power Supply - The power supply unit (PSU) is the piece of hardware that's used to convert the power provided from the outlet into usable power for the many parts inside the computer case.
It converts the alternating current (AC) into a continuous form of power that the computer components need in order to run normally, called direct current (DC). It also regulates overheating by controlling voltage, which may change automatically or manually depending on the power supply.
4. CPU - The central processing unit (CPU) of a computer is a piece of hardware that carries out the instructions of a computer program. It performs the basic arithmetical, logical, and input/output operations of a computer system. The CPU is like the brains of the computer - every instruction has to go through the CPU.
5. Expansion card - An expansion card is a printed circuit board (PCB) that fits into an expansion slot on a desktop computer. An expansion card is used to give a computer additional capabilities.
6. Expansion Slots - An expansion slot is a socket on the motherboard that is used to insert an expansion card, which provides additional features to a computer such as video, sound, advanced graphics, Ethernet or memory.
7. Motherboard - The motherboard is a printed circuit board that is the foundation of a computer, located on the back side or at the bottom of the computer chassis. It allocates power and allows communication to the CPU, RAM, and all other computer hardware components.
8. RAM (Memory Modules) - RAM (random access memory) is the place in a computing device where the operating system (OS), application programs and data in current use are kept so they can be quickly reached by the device's processor. RAM is much faster to read from and write to than other kinds of storage in a computer. Data remains in RAM as long as the computer is running. When the computer is turned off, RAM loses its data. When the computer is turned on again, the OS and other files are once again loaded into RAM.
9. Memory Slots - A memory slot is what allows computer memory (RAM) to be inserted into the computer. Depending on the motherboard, there may be two to four memory slots and are what determine the type of RAM used with the computer.
10. USB Ports – USB stands for Universal Serial Bus and is a plug-and-play interface that allows a computer to communicate with peripheral and other devices.
