Although now there are many who use wireless or who do not need cables because of its practical use and easy installation, but still many people who use a network cable as one way to Connect a computer with an Internet connection.
The use of this network cable has the primary purpose of connecting communications that occur between one computer and another computer and can be used to share files. Network cables also have several types where each type of cable has its own characteristics. Well here will be discussed more detail about the understanding of network cable, network cable function and the advantages and disadvantages of network cables.
Understanding Network Cable
As previously mentioned, it can be said if the network cable is a computer hardware, which is shaped like a cable and is specifically designed to meet the needs as a liaison.
Network cables are used in order to connect from one network device to another device or connect 2 to more computers to be able to share power. The network cable serves as a directional transmission medium in the computer network.
The network cable itself has several types that are well adapted to the needs of the user, network topology used, network size, condition, and protocol. There are 3 types of network cables that are widely used today. The following explanation is more detailed related to each type of network cable:
1. Coaxial Cables
The type of cable in which there are 2 senders, one of which is in the middle of the cable, while the other conductor is surrounded by other conducciling with circular pattern. The principle of this coaxial cable is to deliver a current or signal coming from the source to the desired destination.
But unfortunately this type of cable has been abandoned because the type of port used for the BNC connectors is somewhat difficult to find in the computer or network device. Not only that, the installation for this type of cable is only done by people who are true experts in their field because it needs extra skills when installing connectors.
2. Cable Twisted Pair
A network cable consisting of multiple cables paired. Same thing with coaxial cable type, the working principle of cable twisted pair is to deliver current or signal coming from source. Cable twisted pair are divided into several types, namely STP cable (Shielded Twisted Pair) and cable UTP (Unshielded Twisted Pair).
STP cables have a copper-based wrapper or aluminium foil, this wrapping material is designed to reduce the usual electrical interference often occurs. And for UTP Cable is a cable in which there are 4 pairs of cables that are twisted, almost the same as the telephone cable. The Twisted Pair cable can reach up to 100 meters, no more than that distance. For a wide range of speeds, from 10 Mb/s to 10000 Mb/s.
3. Fiber Optic Cable
For this type of network cable, use copper material for the media. These cables are made from glass fibers or plastic with a very thin size.
Because the glass is based, then of course the signal that is transmitted through fiber optic is a light that comes from the source of the purpose of Eunju. So it is not surprising if the transmission using this type of cable will be faster compared to other types of network cables. It's only common to noise when cables are bent.
Network cable function
The network cable function is to be able to transmit the data that is get from the server and transmitted to the client or user computer. Of course, this data transmission process provides connectivity using cables. The presence of a wired network can of course build a network simply by connecting the cable to the server, user, and hardware in the network.
The use of a network cable is cheaper and reaches all corners compared to wireless. So the use of network cables is still quite popular among today's society.
A network cable is one of the hardware of a computer that is shaped like a specially designed cable and has certain criteria to be a liaison. It can be said if the network cable is a directional transmission medium that is in the computer network.
In addition, the use of network cables also need to support a wide range of qualified and adequate hardware, so that the transmission and transfer of data will be better and avoid interference.
Excess network cable
Network cable is more accessible to remote areas that have no wireless access
- The cost to build using a network cable is cheaper compared to wireless
- More stable network when transmitting data
- Not affected with the surrounding weather
Disadvantages of network Cables
However, the network cable also has flaws that you can see below:
- Requires a lot of cables, especially for large and wide networks
- Please note that in the placement of the cable, do not occur problems such as torn wires caused by being bitten by a rounder.
- Installation involves a lot of cables so it makes the appearance does not look neat
Well that's the explanation regarding the understanding of network cable and its functions, advantages and disadvantages in a computer network. With the network cable, of course make it easier to access the Internet through a computer.
