PC Network Support

It will not be exaggeration to say that information is one of the most important for any business. Dissemination of data involved is also vital. Networks was created to facilitate communication between computers faster and easier. It not only provides faster communication, but has also enabled users to access remote programs and remote databases from the same company or other organizations.

Apart from that, there are other reasons to use computer networks. With computer networks, can reduce costs by sharing hardware and software as well as the downsizing of computer networks instead of mainframe. Gathering information from multiple resources have been easier to ensure the reliability of data.

Since by definition, computer networking is nothing but the process of connecting multiple communications devices for the information and resources can be shared by all devices.


Categorization of computer networks may be based on a wide range of properties used as a medium for communication, scale, networks of communication protocol used topology, etc.

Methods used for computer networks

The communication between two devices, the medium is a must. There are a number of means, such as electrical cables, fiber optic, and radio waves, which are used for networking. Electrical and optical fiber technology used in a wired network, when radio waves in wireless technology works.

Wired

In wired technology, the twisted pair of the most commonly used medium for communication. Quad wire is made of metal wire that are packaged in pairs. Computer network cable contains 4 pairs of son used for data and voice transmission. The purpose of the use of twisted son in order to minimize the noise caused by electromagnetic induction and crosstalk. There are two pairs of twisted son, namely, shielded twisted pair and shielded twisted pair. The speed range twisted pair cable is 2 megabits per second to 10 billion bits per second.

Other media widely used in wireline technology is a coaxial cable. It is mainly used for local networks, systems, cable TV, etc. It is made of wire covered with insulating layers of a flexible material with a high dielectric constant, all with a conductive layer. The purpose of the use of the insulating layer is to minimize noise and signal distortion.

The optical fiber is the second means of communication, invented in the second half of the twentieth century. Its components are fiberglass filaments coated with a protective layer that transmits data using pulses of light. It carries light signals over long distances. Electromagnetic interference can not affect the signals carried by it. The maximum transmission rate can go trillion bits per second.

For all types of cable malfunction, the support network of many suppliers.

Wireless Networks

There are several popular wireless technologies such as wireless LAN, satellite communications technology, communication technology infrared technology to terrestrial microwave, etc.

Wireless LAN technology uses frequency salvation, which is similar to digital cellular radio frequency and low. This spread spectrum technology to connect multiple devices in a limited area. Wireless LAN in an office or at home can be easily implemented with the help of many computer support providers.

Communication satellites using microwave radio signals for the medium as microwave radio signals are less affected by Earth's atmosphere. Data signals, voice and television are sent and received using microwave radio technology.

The infrared signals used in communication between devices over short distances. The maximum distance that this technology is typically 10 meters.

Microwave technology uses little land the gigahertz range of the signal, which limits the transmission to the line of sight. The maximum distance between relay stations, microwave signal is 48 km.

Wireless network equipment is the backbone of business processes and technology that could be hugely damaged if the system runs out of network. In this case, the online support for PC should be used to configure the network system to the right.
