Computer Components: Internal and External Computer Components: Processor: A computer processer, otherwise known as the CPU (Central Processing Unit) is a part of the computer that receives input and decides that the output will be. Many modern CPUs are capable of processing trillions of calculations per second. The speed of a processor measured by how many operations a CPU can do in one second; this is done in MHz or GHz (Megahertz or Gigahertz). A processer with the speed of 1 MHz does 1,000,000 operations per second, and a 1GHz processer does 1,000,000,000 operations per second. This is known as the clock speed. Input: An input is when a computer receives data from external hardware such as a mouse, keyboard Output: An output is when computer …show more content…

This is a microprocessor that allows the computer to boot up. It also allows data manigment between the operating system. RAM: RAM stands for Random Access Memory. It is a bit like a person's short-term memory. RAM is volatile so data only exists only when the computer is turned on, and is used by the operating system and other applications. GPU: GPU stands for Graphics Possessing Unit. It is used for 2D or 3D Graphics, outputting to display monitors,running graphic high intensity applications, etc.This is very mathematically intensive so it takes strain off the CPU. Hard Disc Drive: a HDD is like a person's long term memory. it is used to store any type of data from files to applications. The data on a HDD is non-volatile, which means the data will stay on the disc even if the computer is switched off. A SSD is another way to store data, but it is faster than a HDD because there are no moving parts. Motherboard: The motherboard is where many components such as the CPU, GPU, RAMetc.are connected. The motherboard does not hold any data itself. It also holds ports for input and output devices to be connected, such as a monitor, mouse, keyboard etc. Fans: A fans job is very important as it prevents important parts like the CPU from …show more content…

Case: A case is where all the computer components are mounted; the case protects the components from physical damage and also protects it from static electricity. Optical Drive: uses lasers to read or write data to/from optical discs like CDs or
