- 1What Does CPU Stand ForCentral Processing Unit
- 2What Are The Functions The CPU Carrys Out
- 3What Is Cache MemoryCache memory is special high speed memory used by a computer.
Data that is in use is transferred into the cache memory to make access to it faster. - 4Similarities To RAMBoth volatile (lose all data when power is switch off)
Both used as main memory (primary memory), cache is used to store data waiting to be processed. - 5Differences With RAMCache memory is faster, works at the same speed as the CPU.
Is a lot smaller (MBs rather than GBs). - 6What Is Processor Speed Measured InProcessor speed is measured in gigahertz (GHz) (billions of cycles per second).
- 7What Is RAM• RAM stands for Random Access Memory.
• It is typically used to store programs and data that
the computer is currently using.
• It is volatile, which means that everything stored in
it will be lost when the power is turned off.
• Its content can be changed easily.
• It is usually several gigabytes in size. - 8What Is ROMROM stands for Read Only Memory.
• It is typically used to store the bootstrap loader.
• It is non-volatile, which means that everything
stored in it is kept when the power is turned off.
• Its content cannot be changed easily.
• It is usually several megabytes in size. - 9What Is Virtual MemoryVirtual Memory is storage taken from the hard drive and used as RAM. It is used when the RAM runs low and you need more to handle the programs that are open.
