As we go INSIDE the computer!
11 Now let’s go inside…
12 The TowerThe tower is the enclosure that contains the main components of a computer.
13 Inside the ComputerMotherboard (main board) – Large printed circuit board with thousands of electrical circuits.Power supply – Transforms alternating current (AC) from wall outlets to direct current (DC) needed by the computer.Cooling fans – Circulates air in the system unit to keep it coolInternal speaker – Found on the motherboard and used by the operating system for diagnostics and error reporting—the beeps and other mono-tones. Not responsible for playing music, etc.Central Processing Unit - A microprocessor that interprets and carries out instructions given by software. It controls the computer’s components. It is covered by the…Heat sink, an internal fan, which serves to keep the CPU cool.Storage – Hard drive, RAM, and secondary storage.Graphics and Sound Cards – Expansion cards placed in ports on the motherboard to improve graphic and audio output.Hard Drive—Main storage component on your computer.RAM—Type of memory that stores information temporarily so it can be used by the CPU13
14 The MotherboardThe motherboard provides the centralized connection point for the computer’s componentsElectrical traces (wires) on the motherboard connect to the chips.Sockets allow chips or circuit boards to be added or devices to be connected to the motherboard.14
