Hardware - LU3

These include, the computer itself and all its peripherals and computer software which make it possible for a computer to function.

The CPU is "The brain" of a computer. It takes the instructions from a computer, interprets it and then it tells all the other components of the computer what the instruction it got instructs all the other components what to do.

Performs all the logical and Arithmetic calculations (Addition, Subtraction, Division, Multiplication etc.), and takes care of the speed of all operations.

Deals with Fetching (Getting instructions from the computer memory), Decoding( Taking the instructions and making them commands), Executing (processing), Storing (the instruction is now stored in the computer's memory).

This is a memory spot within a CPU, which keeps values before and after arithmetic operations, but keeps them temporarily.

The motherboard is a printed circuit board that is the foundation of a computer, located at the bottom of the computer case. It allocates power to the CPU, RAM, and all other computer hardware components.

This is a form of computer data storage. A random-access memory device allows data items to be accessed (read or written) in almost the same amount of time, irrespective of the physical location of data inside the memory.

ROM is built-in computer memory containing data that normally can only be read, not written to. ROM contains the programming that allows your computer to be booted up or regenerated each time you turn it on.

This is a high speed type of memory, which forms a part of the CPU. It is a temporary storage which increases processing speed.

This is an erasable type of memory, which can be plugged in in the form of a USB etc.

These are PC Cards, flash memory cards and/or USB flash cards

These are the serial ports, the USB ports and all the buses of a computer

This expresses the max number of the bits of data that is transferretd between the CPU and the main memory

This shows the speed of a CPU internally, normally in Hz, kHz,mHz and gHz

This expresses the actual time a computer takes to get tasks completed
