Sound card
• The sound card is the main component for sound also know as the audio card
• The input and output of audio signals to and from a computer under control of the computer programs.
• Most sound cards are integrated into the motherboard with the video card

CPU (Central processing unit)
• The Central processing unit carries out the instructions of a computer program, it performs the basic input/output operations of the system.
• The power of a CPU is currently measured In gigahertz (GHz) and are 64-bit it ran faster• Newer CPUs use multi cores, this means There is more then one chip inside the processer

Graphics card• The graphics card gives a video output to the
monitor• They mostly use PCI,PCIe and AGP slots to fit into the motherboard but most modern graphic cards are integrated into the
motherboard • They use HDMI,DVI and VGA ports to connect to
the visual display device

Heat sink
• The heat sink cools the computer down so it does not over heat
• It removes waste heat made by computer components
• It keeps components within their safe operating temperature
