CPU

1. Central processing unit

   • It is made up of the control unit and the arithmetic and logic unit (ALU)

2. The control unit uses electrical signals to direct the system execute the stored prorams

3. The ALU carries out arithmetic and logic options

4. Areas of a CPU

   • RAM: A type of computer memory that allows the computer o access data randomly. It is the most common type of memory it fond in computers and oter electrical devices
   • Cache memory: It is a portion of high speed static RAM (SRAM) instead of slower, cheaper dynamic RAM (DRAM)
   • Solid state drive: it is an all-electronic storage device that is an alternative to hard disk
   • Clock speed: the operating speed of a computer or its microprocessor, expressed in cycles per second
   • Fetch execute cycle: an instruction cycle which is the basic operating cycle of a computer. it is the process of a computer retrieving a program instruction from its memory and it determines what actions the instruction requires, and caries out those actions
