A complete computer network exists when more than one computer is connected. The network is for the sharing or resources like software, data and hardware. By extension, this facilitates inter-human communication, business and teleworking amongst others.
Types of Networks There are basically two types of networks, wired and wireless. Wired computers have been there for a while, usually based on a standard referred to as Ethernet. The wired type uses unshielded twisted pair cables. This form of connection is so common that all computers manufactured today come pre fitted with a standard port. To set up the network, the cables are used to interconnect the various workstations and the server, if any. The user will then have to configure each of the workstations, or the main server, for data sharing. The reach of the network is of course restricted by the cable length.
The wireless network works around two standard technologies; wifi and Bluetooth. Bluetooth features a low power, short range reach. They are mostly used for a personal area network which basically covers PDAs, laptops, headsets, mobile phones and laptops. Wifi on the other hand is a long range powerful technology used in a larger area referred to as wireless local area networks (WLAN).
Why Wired network Is Becoming ObsoleteThe first reason why wired networks are becoming obsolete is the ease of portability of the wireless type. Wired network, connected by cables, is usually limited by the reach of the cable, which is usually just a few meters in length at most. The flexibility allowed by the wireless network allows the user to move the work station with ease.
Wired network have always been associated with a large number of hubs as the standard feature. This causes issues in design, as it results to a cluttered feel. With the wireless network all that is required are the hotspot/transmitter and the receiver. This makes for structure simplicity which of course translates to fewer problems.
For large database stations or even small cyber cafe's, adding a workstation to a wired network is a cumbersome process. It often requires addition of routers, adapters and
yards of cables. With a wireless network, all that is required is placing the workstation within reasonable proximity of the signal, installation of software, configuration and you are done. This has resulted in many businesses, particularly those with numerous workstations, to easily phase out the wired technology for the smoother and less cumbersome wireless type.
The Future of Wireless Networks
Wireless networks have grown in popularity over the years due to the aforementioned benefits. The future looks bright as the wired network continues to be phased out. The success of the wireless network around the world has been attributed to having a set standard across the board. The set standard has been the 802.11. Acceptance of this standard has been critical to growth and clients' quick agreement to phase out the wired type, as inter-operability and interchangeability is very easy. The quick acceptance is well shown by the willingness of innovators to quickly build on the 802.11 standard to provide better, faster and far-reaching ranges. These include the WiMAX and IEEE 802.16.
