Homes with broadband have routers that not only give Wi-Fi, but also have the option of Ethernet - typical routers for the small office or home local area networks often have four Ethernet ports, and those for larger offices will typically be dedicated Ethernet routers and Wi-Fi access points will be able to be located as required.
The routers and additional switches will mean that many more Ethernet cables will be needed. Although Wi-Fi is advancing and offering much higher levels of performance, so too is Ethernet, and the associated network cables offer some distinct advantages in many circumstances.
Wi-Fi can be dependent upon the location; whether there are any obstacles on the way, the distance to the router and much more. Ethernet cables offer a reliable level of performance and are often preferred for many offices, and they can be very useful for home local area networks as well.
When thinking about the cable to use, remember that for many connections, it is the Internet connection that is the slowest link. Even fibre broadband will be slower than the average Ethernet cables, so if it is just for Internet surfing only, then a very average Ethernet cable will suffice. When the better Ethernet cables come into their own are when files are transferred between devices for backing up, streaming video, streaming games, and the like. The faster speeds of the more up to date better Ethernet cables can make a real difference.
Often the issues can arise when older network cables are used. Most of us will have an accumulation of Ethernet cables that have been acquired over the years. These may be from earlier standards and may affect performance. If the cable has come with a new Ethernet router, then it is probably one of the newer categories that will be fast. There are a number of Ethernet cable categories that can be seen advertised.
Cat 5, Cat 6, Cat 7 are all widely available, with Cat 5 being the oldest standard and Cat 7 the newest network cable category and with the highest performance.
Using the table below it is easy to see the comparison between the levels of cable performance for when they are bought. One of the good things about the Ethernet cables is that they are interchangeable and they are also backwards compatible. It is possible to plug a Cat 5 cable into a router that has the latest 10G Ethernet interface.
The only issue is that the cable will slow the data transfer down. This may or may not be a problem dependent upon the type of file transfers. Similarly it is possible to plug a Cat 7 cable into an old router that does not support the latest speeds. This means that when buying an Ethernet cable, there is a lot of flexibility - the worst is that the network cable might slow things down a bit.
Ethernet cables come in a variety of standard lengths. Whilst it is possible to construct your own cables, most people will want to use one of the pre-made cables. Cables are widely available in a variety of lengths: 0. Long Ethernet cables are widely available, maximum lengths of around 75 metres are relatively easy to find. For example, consider connecting two computers together. If you use straight-through cable, with identical wiring in both ends, both computers will use wires 1 and 2 to send data.
If computer A sends some packets to computer B, computer A will send that data using wires 1 and 2. That will cause a problem because computers expect packets to be received on wires 3 and 6, and your network will not work properly.
This is why you need to use a crossover cable for such connections. Skip to content. Network switch and router are two basic devices utilized in computer networks. However, many people have no idea how to use them and set up a switch with a router. A network switch, normally referred to as a multiport network bridge, is a computer networking device that connects other devices together on a computer network.
It manages the flow of data across a network by transmitting a received network packet only to the one or more devices for which the packet is intended. Then, how does a network switch work? Normally, a network switch uses hardware addresses to process and forward data at the data link layer layer 2 of the OSI model. While, sometimes, it can also process data at the network layer layer 3 by additionally incorporating routing functionality. It allows different nodes typically computers to communicate with each other in a smooth and efficient manner.
Nowadays, Ethernet switch is the most common form of network switch. In addition to one of its most normal type gigabit Ethernet switch which used at earlier time with a lower speed up to 1 Gbps, another type, 10GbE switch is also very popular with a higher speed up to 10 Gbps.
