Connectors at the back of a computer

​At the back of your computer you will find many connections that are part of that computer’s motherboard.

You can find multiple USB connections, a connection for a monitor, if your motherboard supports video functionality, 

Older computers may have PS/2 connections for a keyboard and a computer mouse. These had been replaced with USB keyboard and a computer mouse. These can also be wireless using Bluetooth technology.

Network Ethernet port can be a part of a computer motherboard, and Ethernet connection can be found at the back of a computer. However dedicated network cards can provide better functionality. Dedicated network cards are usually found in the server systems, desktop systems generally will not require a dedicated network card. Wired network connectivity had been replaced in many homes with WiFi, therefore a need for physical cable is limited.

Audio connections can also be found at the back of a computer. Number of connections will depend on what type of sound is supported by the motherboard, however getting a really good sound from a computer will probably require a dedicated sound card.

On a motherboard you can also find a connector for a monitor, if your motherboard supports video functionality. If it does, then this video will be sufficient to browse the Internet or watch videos. Video games graphics will probably be subpar. Playing video games with good graphics will require dedicated video card. Of course if all you play is a minesweeper or Tetris, then video card with high performance is not required, built in video card into motherboard will be sufficient.
