INTERNAL HARDWARE DEVICES

• MOTHERBOARD
  • The motherboard is a printed circuit board found in all computers
  • It allows the processor and other computer hardware to function and communicate with each other.
  • One of the major functions of a typical motherboard is to act as a kind of 'hub' that other devices connect to.
  • A typical motherboard consists of a sheet of non-conductive material, such as hard plastic.
  • Thin layers of copper or aluminium are printed onto this sheet.
  • These form the circuits between the various components.
  • In addition to circuits, a motherboard contains several sockets and slots to connect the other components.
• RANDOM ACCESS MEMORY (RAM)
  • Random access memory (RAM) is an internal chip where data is temporarily stored when running applications.
  • This memory can be written to and read from.
  • Since it's contents are lost when power to the computer is turned off, it is often referred to as a volatile or temporary memory.
  • RAM stores data, files or part of thr operating system currently in use.
• READ-ONLY MEMORY (ROM)
  • Read-only memory (ROM) is a memory used to store information that needs to be permanent.
  • It is often used to contain, for example, configuration data for a computer system.
  • These chips cannot be altered and can only be read from (hence their name).
