PC Networks
The sharing of fax machines, printers, and modems amongst many computers and users go a long way in reducing operational costs. A database on a PC network s a very important application as it stores much important data. Emails and chats can be used for instantaneous communication if you are part of PC networks.
The computer networks are classified, depending upon their size, as local area networks, LAN; wide area networks, WAN; metropolitan area networks, MAN, and personal area networks, PAN. The topology of the networking can be classified as bus network, ring network and star network. Topology is a word describing how the computer network and resources are all connected.
Networking saves money
The networking hardware basically is made up of wiring, network cards and a hub. Computer network cards are needed so that one computer can understand what the other computer is basically saying. There cards have a unique MAC address to identify computers on a computer network and hubs connect all the computers in the network. Hubs can also be used to connect to other hubs so that the size of the computer network is increased. You can connect two computers together by using Ethernet cards, phone lines or power lines for communication with hardware kits that you will need to purchase.
If at home you are networking and the number of computers starts to increase, then the number of cables and wires is also going to increase. This is where wireless networking is such a fantastic solution. In wireless networking, radio trans-receivers or infrared signals are used to communicate between computers and other devices. Examples of wireless networking include devices such as Wi-fi and Bluetooth technology. There could well be security issues involved in wireless networking. But there still remains to be a definite preference towards wireless networking nowadays among consumers.
Protect against hackers and disasters
If your network setup is not that secure, then any spy can hijack your network and may play around with the intent to do damage for malicious aims. This will certainly not be in your favour at any cost. Therefore it is imperative to have a professional network or IT consulting service from a renowned firm to set up a secure and theft proof computer network for you.
Apart from security, there are other issues such as network failure, which may be caused by any damage. There might be environmental hazards like fire, building damages, or electricity problems. In such cases, there should always be suitable disaster recovery mechanism in place so that you can have backup which may be used to avoid heavy data loss. Implementing a disaster recovery system is not so easy, so you should invest in a professional firm who will consult with you on disaster recovery solutions in computer networking.
We can no longer do without networking
PC networks today have added a new dimension to the 21st century of information technology. Today the cyber world is much faster and wider than the real world, which has all been made possible due to computer networking. Computer networking has revolutionized business, communication, travel, research, defense, society and almost all human endeavors. The development and continual development of computer networks has helped the technological revolution take a big leap forward.
