Ethernet cable 2 – When would you need an Ethernet cable?

Posted by

As the Internet continues to expand and mobile computing begins to become more popular, more and more people are exposed to the use of computer networks. But the kind of networking that people are exposed to these days is not like what it was five years ago. Smartphones do not require an Ethernet cable to connect the device to the Internet. However, there are still plenty of cases where Ethernet cabling would be useful and even necessary. Depending on your situation, you may still need a network cable to get the job done.

The Ethernet protocol is the most popular form of computer networking on the market. It has been around for years and is used in almost every office building in the world. Ethernet became one of those technologies that was so universal that it found its way into the rest of computer networks. Anytime you connect two computers to talk to each other, you are creating a network. When you use an Ethernet cable to connect two computers, you have created an Ethernet network. It might sound complicated, but it’s actually quite simple, and it’s something that home computer users have been doing for years.

When you connect a cable from your computer to your Internet router or high-speed Internet modem at home, you are using Ethernet cables. It is the only protocol used to permanently connect a computer to an Internet access device other than USB. If you are traveling and carrying a laptop, then it is advisable to stay in places where you can have WiFi access for your networking needs. But it’s always good to have a cable with you in case the WiFi doesn’t work. If you book a hotel room that allows WiFi and wired internet access, then you know you’ll always be able to get online.

People use computer networks at home, in the office and on the go. The cable you’ve used for years to connect your home computer to the Internet is the same Ethernet cable you use to connect your work computer to your corporate network. People often don’t realize how widespread the Ethernet protocol is in their lives. Once you realize how much you really rely on computer networks every day, you start taking the necessary precautions to make sure you’re always connected.

Ethernet cables – what do the category numbers mean?

Almost every home and office has a computer and access to the Internet. Some computers access the Internet using wireless technology such as wifi, while others use a cable to connect. An Ethernet cable connects to a modem, switch or router via an RJ45 Ethernet socket. Various cable specifications are available. Cat5e is the most commonly used lead, having almost replaced the slower Cat5 standard. Cat6 is typically used in office environments and newer network installations because it offers reliably faster speeds when using longer runs.

Cat5 cable is capable of speeds of up to 100 Mbps. Cat5e operates at speeds of up to 1000 Mbps. The only caveat is that the longer the cable, the lower the speed. The maximum length for Cat5e is 100 meters. In theory you should be able to achieve speeds of 1000 Mbps (Gigabit network speed), but in practice these speeds are only achievable over shorter distances of up to 30 meters using Cat5e. Quality is also an issue. Using a shielded cable helps because it reduces crosstalk issues. Crosstalk is caused by electromagnetic interference from other cables or electrical equipment located nearby.

Cat6 cable offers true Gigabit support with an effective speed of up to 10,000 Mbps over a distance of up to 100 meters. As with all Ethernet cables, the length, shielding level, and even physical location of the cable can affect network speed. If you use a long cable placed next to existing cable runs and the maximum speed is likely to be reduced. Launched in 2008, the Ca6a is certified to higher standards and offers better shielding, reducing crosstalk and enabling higher speeds over longer distances.

Category 6 Ethernet cable is backward compatible with Cat5e. Due to the low price difference between Cat6 and Cat5e cable; many people actually opt for Cat6 cable because the cable itself is of better quality with better crosstalk prevention.

You can expect to pay around £28 for a 30m Cat6 cable and £5 for a 2m cable, while a Cat5e cable of the same length should cost around £15 and £3.50 respectively, UK prices. There are many online retailers that offer very competitive prices for ethernet cables, indeed some of the longer cables can easily be obtained online only, as many local computer stores are not very demanding on 50m ethernet cables.
