Wired Methods of Connecting Devices

Wired Methods of Connecting Devices

1. USB - Commonly used with most peripheral devices.

   • Pros - Fast data transfer speeds, multi devices can connect to the same port, provides power to devices and is compatible with most devices.
   • Cons - Relatively short ranged

2. SATA - The most commonly used connector for internal storage devices

   • Pros - extremely fast data transfer speeds and is compatible with most devices
   • Cons - Relatively short ranged and doesn't provide power.

3. VGA - Commonly used with older display devices.

   • Pros - Older technologies will be compatible and has a built in locking mechanism
   • Cons - Analogue signal degrades, can't achieve very high resolutions and doesn't transmit audio with the video

4. HDMI - Commonly used for modern display devices

   • Pros - capable of 4K resolution output and audio can be transmitted with video
   • Cons - It has no locking mechanism

5. Ethernet cable - Used to transmit data between computers, often in a LAN or home network.

   • Pros - it is reliable when transmitting data, it has good range (100 meters) and is compatible with most devices.
   • Cons - limits mobility compared to WiFi, not compatible with most mobile devices and cannot be used over very long distances

6. Fibre Optic - Commonly used for transferring data over long distances, e.g. telephone network

   • Pros - extremely fast data transfer speeds, very long range and very secure when transmitting data
   • Cons - Very expensive to implement and run
