The network of the Computer could be interpreted as an association of the interconnection of several autonomous computers. Two computers it was said formed some network when both of them could change mutual information. The restriction on the autonomous term here was to distinguish with the master's system/slave. When a computer could make the other computer active or not active and controlled him, then this computer computer was not autonomous. A system with the manager's unit (control the unit) and several other computers that was slave not a network; the big computer with re-beads printer and the terminal also not a network.
The benefit of the Network of the Computer
Generally, the network had several benefits that more compared with the independent computer and the business world again admitted that access to modern information technology always had the competitive superiority compared with the competitor who was limited in the technological field.
The network enabled the management of resources to be more efficient. For example, many users could share with each other printer single with the high quality, was compared used printer the low quality in respectively the working table. Moreover, the licence of network software could be cheaper compared with the licence stand-alone was separated for the number of same users.
The network helped maintained information so that continue to andal and up-to-date. The storage system of the data was focussed that was managed well enabled many users mengaskses the data from various different locations, and restricted access to the data when being processed.
The network helped sped up the process of sharing the data (the data sharing).
The transfer of the data in the network was always faster compared with means of sharing the other data that not the network.
The network enabled the working group to communicate with more efficient. The letter and delivery the message of electronics.
There were three types of the general network that was used in part:
* the Network WorkGroup,
* the Lan Network,
* the Wan Network
The Workgroup network
This network consisted of several computer units that were connected by using Network Interface Card or that normally is mentioned with Local Area Network Card, as well as by using the BNC cable and UTP. Semua the computer unit that terhubung could access the data from the other computer unit but also could do print document in printer that terhubung with the other computer unit. The Workgroup Network profit. The exchange file could be carried out easily (File Sharing). The use printer could be carried out by all the computer units (Printer Sharing). Data access from/to the other computer unit could in restricted with the level of the security in password that was given. Communication could be between the employee carried out by using the E-mail & Chat. When one of the computer units terhubung with the modem, then all or some computer units in this network could access to the network of the Internet or sent fax through 1 modem.
The LAN network
LAN (Local Area Network) was a computer collection, where being gotten by several computer units (client) and 1 computer unit for the data bank (server). Antara was their respective client and between client and server could change each other file and used each other printer that terhubung in computer units that terhubung in the network of LAN. Berdasarkan the cable that was used ,ada two LAN network instructions, that is and the BNC cable and the UTP cable.
The LAN network profit:
The exchange file could be carried out easily (File Sharing). The use printer could be carried out by all client (Printer Sharing). File-file the data could be kept in server, so as the data could be accessed from all client according to the security's authorisation from all the employees, who could be made be based on the structure of the organisation of the company so as the security of the data was guaranteed. File the data that went out/entered from/to server could in the control. The process backed up the data to more was easy and fast. The risk of losing the data by the computer virus became very very small. Communication could be between the employee carried out by using the E-mail & Chat. When some client/server terhubung with the modem, then all or some computers in the LAN network could access to the network of the Internet or sent fax through 1 modem.
The WAN network
WAN (Wide Area Network) was the collection from LAN and/or Workgroup that was connected by using the modem communications equipment and the network of the Internet, from/to the head office and the branch office, and between the branch office. With this network system, the exchange of the data could be between the office carried out quickly as well as at a cost of that was relatively cheap. This network system could use the network of the available Internet, to connect between the head office and the branch office or and PC Stand Alone/Notebook that was in other the city or the country.
The WAN network profit:
Server the head office could function as the data bank from the branch office. Communication could between the office use the E-mail & Chat. The document/File that usually is sent through fax or the package of the post, could be sent through the E-mail and the Transfer file from/to the head office and the branch office at a cost of that was relatively cheap and in a period of that was very fast. Pooling Data and Updating Data could be between the office done every day when that was determined.
