Processor speed

Processor speed

1. One cycle per sec= 1Hertz (Hz)= 1 instruction carried out each sec.

2. 1 Kilohertz (kHz)= 1000 cycles per second

3. 1 megahertz(MHz)= 1,000,000 cycles per sec

4. 1 Gigahertz(GHZ)= 1,000,000,000 (1 billion) cycles per sec

5. RAM allows the computer to read data quickly and efficiently to be able to run applications efficiently, whereas ROM stores the program required to initially boot the computer and perform diagnostics. RAM is a common type of memory found in computers and printers, and can go up to a few gigabytes

   • RAM- is a form of permanent storage while RAM is a form of temporary storage
     • temporary
       • Random Access Memory
   • ROM- is non-violate while RAM is volatile memory
     • permanent
       • Read Only Memory
   • ROM can hold data even without electricity while RAM needs electricty

6. when u switch a computer, small program held in ROM called the bootstrap loader is automatically executed. The program performs some self-tests, and loads the operating system into memory- RAM
