Understanding of Computer Networking Fundamentals

A computer network is a collection of two or more computers with communication between them through a medium. The communication medium can be through radio waves, wires, infrared, optical fibers etc.

Computer network is an integral part of our daily lives, with the most important reason being that of communication. The use of computer networking is to share resources like fax machines, printers, modems, files etc., and its other uses are database server, computer server, email, chat, internet etc. The computer to which the resources are attached is called the server and the other computers that access the resource are called clients. In peer-to-peer computer networks there are no servers.

The sharing of fax machines, printers, and modems amongst many computers and users reduce the operational cost. A database on a computer network is a very important application as it stores and runs many important data and jobs. Emails and chats can be used for instantaneous communication and sending of files on a computer network.

The computer networks are classified, depending upon the size, as Local Area Networks (LAN), Wide Area Networks (WAN), Metropolitan Area Networks (MAN) and Personal Area Networks (PAN). The topology (topology is the way the computer networks and network resources are connected) of the networking can be classified as Bus Network, Ring Network and Star Network.

The networking hardware basically consists of wiring, network cards and a hub. Computer network cards are required so that one computer can understand what the other computer is “talking”. Network cards have a unique MAC address to identify computers on a computer network. Hubs connect all the computers in the network. Hubs can also be used to connect to other hubs to increase the size of the computer network. Two computers can be connected using Ethernet cards or phone lines or power lines for communication, with hardware kits available at roughly a cost of $100.

Infiniti Releases Sketch of Sleek 2013 Electric Car

Infiniti has released a teaser sketch of a luxury electric vehicle the automaker says will launch in 2013.The as-yet unnamed five-seater is likely the Nissan Leaf-based electric vehicle we're expecting from Infiniti.It's unclear how the electric vehicle's range and power will be affected by changes required to make it meet Infiniti's standards.

As we've seen with the lackluster market performance of the hybrid-only Lexus HS 250h, styling will be a key factor for the Infiniti. The preliminary Infiniti sketch shows a small car with pulled back headlights and a black roof, suggesting it might be a panoramic sunroof. Five-spoke wheels have centers featuring a glowing Infiniti sign.

Naturally, the section of the sketch we find most interesting is the blurriest. The Infiniti electric vehicle could prove to be a hatchback like the Leaf or Toyota Prius, or may simply be a sedan.Regardless, we'll have the latest on this electric car as it comes into focus over the next couple years.

About Technology

Technology is the process or like that technique by which humans modify nature or surround to meet their needs.But technology is more than these tangible products. We can growth to technology in any field. By technology we made comfortable & luxurious.Technology is the part of engineering. Some peoples think about technology in terms of its artifacts: computers and software, aircraft, pesticides, water-treatment plants, birth-control pills, and microwave ovens, to name a few.

In technology,there is includes all of the infrastructure necessary for the design, manufacture, operation, and repair of technological artifacts, from corporate headquarters and engineering schools to manufacturing plants and maintenance facilities. The knowledge and processes used to create and to operate technological artifacts -- engineering know-how, manufacturing expertise, and various technical skills -- are equally important part of technology.
