What is the Definition of Cable?
Cables are quite a common sight in the modern world. You use it to recharge your Smartphone or tablet, or laptop, use it to connect multiple devices, and complete other works.
Technologically speaking, a cable is a thick wire or a group of wires banded together inside an insulator covering like rubber or plastic. Cables are used in electricity transportation or carrying electronic signals. It is also known as plugs, cords (which is quite a popular name) and connectors.
A monitor cable is a specialised cable that serves the purpose of connecting the CPU parts. If you want to set up a PC or want to connect different devices with your laptop. Here, you will find a detailed guide on monitor cables and how to use them.
Monitor Cable Types
1. VGA Cable
The acronym VGA stands for Video Graphics Array. It is a cable that is used to send video signals from a device to another. The VGA cable works as a connection between the monitor and your PC screen and sends video waves. This AV cable was first discovered and patented by IBM in 1987.
At present, VGA cables are found for video streaming of different resolutions- 1080p, 480p etc. This cable can receive analogue RGB signals and transmit the video signals after the RGB one.
Please note that VGA cables are only able to transmit videos. They cannot transmit audio signals.
- A VGA cable comes with two ends, a small pin-sized end and another in a 15-pin D-sub port which looks like a square-shaped pin with 15 homes in it.
- Since both ends have different ports, it is called a male-female monitor cable. Its different ends are necessary for transmitting signals in only a single way. The D-shaped plug is fitted in the screen while the pointed edge is fitted in a plug point of the monitor. You will find most of the VGA cables come in blue or back colour.
The VGA cable helps to transmit video signals in a single direction. With the help of the VGA cable, you can play videos on your PC.
2. USB Cables
Universal Serial Bus cables or USB cables are now extremely common. These are used for connecting units of a PC, for charging devices and so on. Moreover, USB cables are also used to connect peripheral devices like printers, mouses, cameras etc.
You can find different types of USB cables in the market which are used for different purposes.
Types of USB Cable Connector
a. USB 2.0 Type A
USB A cables are one-way cables and are used widely. One way of this cable is a smaller pin, with another one having a larger pin. Since it is a one-way cable, it will only go into the port one way. The side with the USB symbol or USB word written is you need to connect to your PC. It usually works on the host controller of the device.
The USB A cable is found in many types. The USB 2.0 port is often used in mouse, phone chargers etc.
On the other hand, the USB 3.0 Type-A comes with an additional pin. Hence, it is wider with two small pins protruding on both sides of a regular 2.0 port. It is commonly used for transferring data with a bandwidth of 5 GHz.
