What is Ethernet cable ?
Ethernet is a type of “local area network” technology. Using it, computers and networking devices are connected. Not only this, you can also share information through it. Here the data of TCP/IP Stalk is related to the link layer. Its specialty is that it can simultaneously connect networking devices located at short distances. Especially the help of cable is taken to connect Ethernet to the computer. This cable is called Ethernet cable. Whenever a network has to be established, a special protocol is required to make it work. Well, protocols are rules made for networks. Ethernet is also a form of network protocol and is used to create a LAN network. It was developed by Xerox in 1970. At that time its speed was very normal, around 2MB to 3MB. Its standard name is IEEE802.3.
How many types of Ethernet are there?
Types of Ethernet-
1. Fast Ethernet-
In earlier times, when Ethernet was created, its speed was very slow but gradually it got updated continuously and then today its maximum speed is 100 Mbps. This is what is defined as Fast Ethernet. Through this we can do internet surfing, video, graphics etc. without any interruption.
2. Gigabit Ethernet-
To use multimedia and Voice over IP, a special fast network is required. Gigabit Ethernet was created mainly to achieve this speed. Today it is being widely used and in this type of Ethernet, Twisted Pair and Fiber Cables are used to connect computers together.
3. 10 Gigabit Ethernet-
Its speed is very fast and has left its mark in today’s modern world. Its maximum data transfer rate is 10 gbps. Meaning that it is possible to transfer data at a speed of 10 GB per second. In comparison to other Ethernet, it works completely on optical fiber cable connection. This is very latest. Its specialty is that it is quite unique from the standard LAN design because it broadcasts data to all the nodes.
Tell the types of Ethernet Cable?
Types of Ethernet Cable –
1. Twisted Pair Cable :-
This is the most commonly used cable and consists of two or more pairs of copper wires encased in a predominantly plastic sheath. Its thickness can be up to a maximum of 1 kilometer. There are two types of cables here
(a) Shielded Twisted Pair
(b) Unshielded Twisted Pair
2. Coaxial Cable :-
This is a different type of cable. There is only one wire in it and even there it is covered with insulator, metal shield and plastic cover. There are also two types of this.
(a) Thin net
3. Fiber Optic Cable :-
There is a very famous cable here today. On top of this there is a layer of special plastic called trading. Through this, light single transfer is done instead of electrical single and the speed of data exchange is maximum from 100 Mbps to 2 Gbps or even more. There are two types here.
(a) Single Mode Fiber
(b) Multi-Mode Fiber
What are the benefits of Ethernet?
Some advantages of Ethernet –
1. The cables used in Ethernet are noiseless.
2. There is no impact on the quality of data while transferring data through them.
3. Ethernet has a very high level of security. Hackers are not able to hack the data even with best efforts.
4. Their price is also low.
5. It is very simple to maintain and troubleshoot this type of network.
6. Ethernet mainly does not require a switch or hub.
What are the disadvantages of Ethernet?
Some disadvantages of Ethernet are as follows –
1. Ethernet can be used only for short distances.
2. When many devices transfer data simultaneously, it can sometimes cause technical problems.
3. It is impossible to establish a large network through Ethernet.
4. Ethernet technology provides a kind of non related service.
