Internal PC components

Internal PC components

1. cooling system

   • Heat is generated by the flow of current between components
   • the air flow from the fan in the case allows more heat to be removed
   • If there is too much heat built up it can damage the components and if the heat is not removed it can make the computer run slower

2. CPU'S

   • The central processing unit is considered the brain of the computer because it is where most of the calculations happen
   • it executes a program which is a sequence of instructions which are stored
     • it executes the program by processing each bit of data as directed by the program and instructions

3. Motherboards

   • The motherboard is the main printed circuit board
   • contains buses or electrical pathways found in the computer
     • Buses allow data to travel between components that compromise a computer

4. RAM

   • temporary storage for program and data that are being accessed by CPU
   • RAM is a volatile memory meaning that the contents are removed when the computer is turned off
   • The maximum amount of

5. Power supply

   • The power supply must provide enough power for the components that are currently installed

6. ROM

   • are located on the motherboard and other circuit boards. ROM chips contain instructions that can be directly accessed by a CPU

7. Memory modules

   • Memory modules can be single-sided or double-sided. Single-sided memory modules contain RAM only on one side of the module. Double-sided memory modules contain RAM on both sides
   • The individual memory chips, called dual inline package (DIP) chips,

8. Adaptor card and expansion slots
