Computer Cable Networks - types and uses FAQ

Many types of network cables are used for the construction of networks of computers. These cables are used to meet the varying needs of different types of computer network. Before setting up a network, you need to know the variety of network cables.

To set up a computer network, you must understand some basic terms. With switches, hubs and cables in a common computer network, but for maximum profitThe efficiency, the right kind of equipment and lines necessary. The cables are separated in terms of speed for data transmission, reducing crosstalk and how to install. Find answers to frequently asked questions (FAQ) about the different types of network cables and their uses.

Question: What is a network cable is not shielded?

A twisted pair are widely used by Ethernet networks. The twisted pairs of wires in the cable, as the name suggests, are not shielded. Eight individual copper wires (22 or 24 gauge) four-pair, making the sign of corruption by electromagnetic interference limits. UTP cable must meet the requirements for the number of rotations that are allowed in a defined length. A relatively small diameter of the cable during the installation of an advantage. The speed and throughput of this cable is 10 to 1000 Mbps and is the most convenient> Network Cables. This cable is very popular because it can be used effectively with the critical network infrastructure.

Question: What is a shielded network cable?

R. In twisted pair shielded cable, a metal foil to wrap each pair of copper wires that are then used in a total overlapping wire mesh. STP not only reduces external interference such as EMI and RFI radiation, but also the electrical noise in the cables asCrosstalk and pair-pair coupling. It is usually installed with STP data connector, but also based RJ. In contrast to UTP, are a pair in this series and only two are relatively difficult to install. During installation, you must ensure that the metallic shield grounded at both ends.

Question: When I need a shielded cable and what kind do I need?

A. The primary use of shielded cables will improve the signal transmission paththe cables and protect them from interference such as crosstalk, electromagnetic interference (EMI) and radio frequency interference. This disorder usually occurs if there are any bends or crimps in the neighboring structures. These cause the transmission of data to slow down. Common sources are causing interference by large motors and generators, radio towers and high-voltage lights.

Question: What is a crossover cable?

A. A crossover cable, also known as cross wiredCable is a cable network that is used to connect two network devices without the need for a hub or switch. These cables are completed clearly on their ends with pairs of green and orange. This cable also allows you to directly access the hardware on the same network.

Question: What is an audio cable?

A. Inside the jacket of a solid cord, which is also known as a tow cable, there is only one piece of copper wire. Solid wireprovide mechanical strength and because it is a single conductor, this cable can be used for structured cabling within a building. In an insulation displacement connection, is simple, solid, however.

D. Cos' is a thread?

R. One strand consists of many thin copper wires in a bundle with a jacket. Each of these fine wires inside the cable can be bent and flexed easily. Because of their flexibility, these cables are mainly to make patch cablescan be simply connected, installed and connected. Even if the hoses are often distorted these effects or damage to the power of the signal.

D. What kind do I need one or blocked?

A. Although both the cables, single-stranded and have the same intensity of the signal cables are considered more flexible for short periods because of their flexibility. On the other hand, filled cables are much better for long cable runs.

Question: What is the maximum length?

A.The recommended maximum length of network cable is 330 feet (100 m), based on solid wire, as it is the preferred choice for the maximum length of the base. Always make it a point to use the repeater for the length of the cable connection. The distance between the two patch cables should be 30 feet (8 m). another thing you need to pay attention to is the curvature of the cable. Because they are designed with the lowest ability to flex, the signals in the event of a serious decline can be slowed.

Q.What is RJ45?

A. Like the lines on the road for traffic control, connect the end of the cable, line-up in physical locations of wires in itself. In the network installation, RJ45 connectors are used specifically for connecting Ethernet devices.

Wireless networks - rapidly becoming the standard setup

Wireless networks have become incredibly popular - so much that exists in virtually every new laptop, wireless network cards as part of a series of standard features. In fact, customers are the sellers offer a strange, blank look if wireless networking is not included as a standard feature. People love the convenience of being able to boot the laptop to surf the Internet wherever they are.

> Wireless networks have become so popular and convenient that many people are deciding now, this convenience in their homes too. If you happen to choose an installation of thousands of people who have wireless networks at home, then there are some things you need to know how wireless networks work to understand.

Wireless Network Repeater

One of the best and most interesting features of wireless networks is the fact that they > Wireless. This makes installation simple and gives you the freedom to roam wirelessly with your laptop at home. The need for wireless networks with traditional Ethernet wires are connected.

Installation of wireless networks at home is fairly painless. Furthermore, compared to the traditional wired network or Ethernet, is relatively inexpensive. Many times, you can set a> Wireless network at home for less than $ 100. The only drawback is that wireless networks are a bit 'slower than Ethernet networks. However, the average consumer will not even notice the difference.

The more wireless networking technology for home use operates on the so-called 802.11g. This means that the data sent across the network at 2.4 GHz with a transmission speed54 megabits. For non-technical people, it means that the data is moving very fast. New technology is currently in the works for wireless networking (802.11n), but is still in beta, or test phase.

Wireless networks operate on either radio waves or infrared light pulses modular. These include a router that connect to the Internet via cable, and transmits the data via these radio waves or light. The computer receives the information viais an internal or external wireless adapter that acts as a receiver.

If you think that installing a wireless network at home, you need access to high-speed Internet, a router and wireless adapter for each computer you want to access the network. The basic wireless routers have a range of only about 100 meters, so if you choose to live in a bigger house, you may need to buy a range extender or repeater for yourAnd that's pretty much all the Net.

Wireless networks are easy to install and affordable. If you have not already decided to bite the bullet and install in your home, you're not. Installation requires only reading and a few simple instructions. Do this and you will enjoy a wireless network for the whole family.
