2.2 Explain the purpose of common internal computing components Flashcards
Motherboard/system board
is a large circuit board that acts like the computer’s spine. It links all the parts together and sends electrical signals between them.
Firmware/basic input/output system (BIOS)
is what starts up and checks the hardware components on the motherboard.
(RAM)
Random-access memory
Only works when the computer is on
- Volatile storage devices that hold computer data and program instructions while the computer is turned on.
(CPU)
- Central processing unit
- The brain of the computer
- Principal microprocessor in a PC or mobile device responsible for running firmware, operating system, and applications software.
(GPU)
- Graphics processing unit
- Use for gaming
- Type of microprocessor used on dedicated video adapter cards or within a CPU with integrated graphics capability. GPUs can also perform cryptographic operations efficiently, and are often used for password cracking.
Storage
(NIC)
Network interface card
- a piece of hardware that allows computers to communicate with other devices on a network. To just connect to the internet
Wired vs. wireless
Most motherboards today include a built-in NIC, while some high-end motherboards and server boards feature two or more network ports. Some NICs use a wired RJ-45 connection, while others support wireless connections.
Onboard vs. expansion card
Onboard- A chip or other hardware component that is directly attached to
Expansion- a hardware component that you can insert into a computer’s expansion slot to enhance its functionality
