Successful computer networking, what are the key components to a successful computer network? The most important component other than the computers themselves would have to be the Ethernet cable used to link the computers in order to make a network.
The key role of the Ethernet cable, also known as network cable or patch leads is the transfer data from one device to another without losing any of the information. An Ethernet cable usually has an RJ45 connector at either end; (The RJ in RJ 45 stands for registered jack and refers to the wired jack). This generally looks like a telephone cable. The RJ45 Ethernet Cable is possibly the favourite piece of equipment in the UK, these being the main source for data transfer and networking.
The importance of the Ethernet cable is vast, without such cabling the advances in modern IT technology would be worthless, it is essential to networking computers, allowing people to communicate with each other at the touch of a button, to gain faster internet connections, cabling prior the modern Ethernet cable was big and bulky and insufficient in the transfer of data, they required a higher level of maintenance in order to keep systems up and running and often lost data during transfer, however today's network cables are slimmer and far more effective, rarely losing any information during transference.
One issue these days associated with network cables is the issue of cable management; cable management isn't purely used to make cables tidy, its main function is to keep network cables safety out of the way, reducing risks of being pulled, broken, unplugged but more importantly in perfect working
order.
For most of us who simply reap the rewards of using computer networks in our jobs, we don't pay much attention to the system behind the setup. For anyone who doesn't know what a network cable looks like you merely have to look under your desk.
If you took a look at the inside of an Ethernet cable you would find that it is pretty basic looking, consisting of 4 pairs of copper wires twisted around each other, each pair will be colour coded to identify them easier, this provides the physical medium for an Ethernet network. There are 3 different standards of copper medium used, these are used running at 10Mbit/s, 100Mbit/s and 1000Mbit/s all using the same connectors, RJ45's. After this it all gets a bit complicated, for example deriving a cables maximum transmission speed megabits per second (Mbit/s), however all 3 standards support full-duplex and half-duplex communication, which operate over a distance of a maximum of 100 metres.
There are in fact 2 types of twisted pair Ethernet cable, these are straight through or cross-over they differ by the positioning of the pins in the RJ45 connector. Straight through will be where all pins are connected to the same at the other end of the cable whereas cross-over cables will have pins 1,2 connected to 3,6 at either end. Straight through and cross-over will be clearly marked when purchasing so there will be little room for buying the wrong sort. Straight through cables are usually the required Ethernet cable for normal wiring of a pc to hub.
As you can see, the Ethernet cable is far more important to business than it sounds, being at the very heart of data transfer, LAN networking and sharing vital information within a business environment, it is also the basis of communication globally.
