In the present Information Age, computer networks have contributed greatly to information sharing, through support for electronic communications and access to the Information Superhighway – the Internet. A “Computer Network” refers to an interconnection of two or more computers and other related devices, basically for information sharing.
The whole world is going wireless! The new technologies and standards that have been published in the past decade mean that almost everything we touch, every aspect of our lives have a wireless component in it. From cordless phones in the homes to cellular phones that are used throughout the world – to wireless local, metropolitan and wide area networks.
Just as personal computers (PCs) in the 1980s forever changed how we work, and the internet in the 1990s dramatically changed how we acquire information, wireless communication is revolutionizing the way we live. Using wireless networks to send and receive messages, browse the internet and access corporate databases from virtually any location across the globe has become a commonplace. A wide array of devices, ranging from computers to digital cameras, laser printers and even refrigerators can already communicate without wires.
Almost every type of business needs a computer network, but many are unable to install traditional wired networks because of the physical limitations of such systems. Wireless networks can go where regular wired networks cannot. Wireless Applications i.e. the use of wireless communication technology in conducting day-to-day business activities, can be found in any industry whose employees need the mobility and freedom to conduct business without being confined to a specific location. Industries and fields such as education, construction, healthcare and government agencies are among those using wireless technologies to make a number of activities to occur more quickly and conveniently.
All wireless networks transmit and receive data over the air, using the electromagnetic wave – specifically infrared, microwave or radio wave signals. Wireless networks can be grouped into three main categories; Wireless Personal Area Networks (PANs), Wireless Local Area Networks (LANs) and Wireless Wide Area Networks (WANs).
