Computer science hardware mind map

CPU
1. CPU stands for Central Prosesing unit
2. The CPU is where the computer performs arithmitc and Instruction and logic tasks
3. The clock speed OR clock rate - indicates how fast the CPU can run. This is measured in megahertz (mHz) or gigahertz (gHz) and corresponds with how many instruction cycles the CPU can deal with in a second.
4. CATCHE is used to temporarily hold instructions and data that the CPU is likely to reuse. MOTHER BOARD The motherboard is a circuit board that connects the CPU to the memory and all the other hardware. AND BRIDGES and memory like RAM and ROM are the different parts of the CPU
ram
1. RAM stands for Random Acccsess memory
  1. The RAM is the memory that can be changed by a program and you do lose every thing when the computer is tuned off
  2. The RAM is volitile as when you turn the computer off all the memory is lost
ROM
1. ROM stands for Read only memory
  1. The ROM is the memory that cannot be changed by a program and you do not lose every thing when the computer is tuned off
  2. The ROM is volitile as when you turn the computer off all the memory is saved
