Computer networking- world at your click

Computer networking refers to an interconnected group of computers. The networks are classified on the basis of various factors like scale, connection method, and network relationships and depending on the size they are known as Local Area Networks (LAN), Wide Area Networks (WAN), Metropolitan Area Networks (MAN) and Personal Area Networks (PAN).

For a working network it is essential to know your computer hardware. The computer hardware and networking hardware basically consists of wiring, network cards and a hub. Computer network cards are used so that a receiver computer can interpret what information the sender computer has sent. Network cards have unique MAC address used to identify computers on a certain computer network. Hubs are machines that connect all the computers in a single network; they are also used to connect to other hubs to increase the size of the computer network if needed.

For a bigger network it is more sensible to opt for a wireless networking. In wireless networking, radio transreceivers or infrared signals are used to communicate between two computers or devices. A few much used examples of wireless networking are our very own Wi-fi and Bluetooth technology; still there is a hitch of security issues involved in wireless networking. Even though the current scenario is ruled by the wireless networks as it is most used by the people and youth.

A good computer networking takes place if there are proper professionals working for you. There are even many institutions that train people in computer networking and computer hardware. They after qualifying, get into money earning profession. Major companies employ professional who are CCNA certified. Cisco-Certified Network association includes training in Routing & Switching, Design, Network Security, Service Provider, Storage Networking, Voice, and Wireless. For you to do extremely well with software or hardware the CCNA certification is the most important.  This certification guides you for the highly developed networking security, voice, wireless and video solution. This has given a way to a new and emerging profession that is being opted for by youth these days, adding a new technological dimension to the 21’st century.

When you sit on the computer and log onto the internet for surfing, all you are doing is computer networkingbecause internet itself is an immensely huge network through which you can connect yourself from one end of the globe to another without much delay. A list of advantages of computer networking are-

• Connectivity and Communication- the networking helps to connect numerous computers and this makes business very convenient as you can spread it to the world.
• Hardware resource- you can share one single printer with multiple employees at a work place through network.
• Data sharing-it becomes much easier for you to share an image or file with your relative just through networking.
