What is Computer Network

Three centuries before the present, each marked with different dominance. 18th century was dominated by the development of a mechanical system that accompanied the revolution tradition. The 19th century is the era of steam engines. The 20th century, radio technology, tv and computers play a role for the collection, processing, distribution and media information. The 21st century, where global computer network technology capable of reaching all areas of the world, the development of systems and technology used, dissemination of information via internet, the launch of communications satellites and communications devices wirelees / provider, marking the beginning of the century of the millennium.

Since memasyarakatnya Internet and Windows 95 operating system marketed by Microsoft Inc., to connect multiple computers either personal computers (PCs) and servers with a network of this type of LAN (Local Area Network) to WAN (Wide Area Network) into a common and easy. Similarly, the concept of downsizing and lightsizing aimed at pressing the budget (budget efficiency), especially for the computer equipment is one thing that can not be inevitable.

Thus, a computer network is the set of interconnection between two or more autonomous computers connected by transmission media cable or wirelessly (wireless). If a computer can create other computer restart, shutdown, or perform other control, then the computers are not autonomous (not to exercise control over other computers with full access).

Two tekoneksi said computer unit if they can exchange data / information, various resources owned, such as files, printers, then the storage (floppy disks, hard drives, cd-rom, flash disks, etc.). The data in the form of text, audio, and video media moving through wires or wirelessly (wireless) to enable computer users in computer networks to exchange files / information, print on the same printer, and using hardware / software that is connected in a network together -the same.

Each computer, printer or peripherals that are connected in a network is called a node. A computer network comprising at least two computer units or more, can amount to dozens of computers, thousands, or even jutaaan nodes that are connected to each other.

Such is the history and definition of computer network can be summarized that I wrote based on the knowledge I have. Hopefully bermamfaat, thanks and good luck.
