1.2 Memory

1. Cache: A special type of computer memory that can be accessed much faster then RAM

2. Solid State/ Flash storage: Uses transistors Solid state refers to no moving parts

3. Virtual memory: It stores information from Ram that is not needed urgently

4. Ram: It is a type of memory that you can change and read what information is stored. Applications and programms use this memory for your settings etc. The information is stored. Applications and programs use this memory for your settings etc. The information is temporary and when power is lost so is the information

   • RAM is a volatile storage. RAM makes our computer faster when booting up your computer.
     • Volatile means that the information can change quickly and upredictdly for the worse.

5. ROM: As ROM stands for Read Only Memory it implies that programmer or user of the monitor can not change the instructions given/stored in the ROM. When power is lost the information is not lost/removed

   • Dynamic means the memory is refreshed constantly.
   • Static means that it will stay the same until the power turned off.

6. Registers

   • ALU
     • Used to perform arithmetic and logic operations.
   • MDR
     • Holds contents of the memory which is to be transfered.
   • Cu
     • Tells the computer how to respond to the program's Instruction.
   • ACC
     • This is where arithmetic and logic calculations are stored.
   • CIR
     • Holds the current Instruction to be executed, having being fetched from the memory.
   • MAR
     • Holds the memory location of the data that needs to be accessed.
       • It can hold either a data address or an instruction address.
