Electronic Mail : E-mail aids in personal and profession communication.Resource Sharing : Resources such as, printer, fax machines and modems can be shared. #COMPUTER NETWORKS PDF NOTES IN HINDI SOFTWARE#Centralize Software Management : Software can be loaded on one computer (the file server) eliminating that need to spend time and energy installing updates and tracking files on independent computers throughout the building. #COMPUTER NETWORKS PDF NOTES IN HINDI PASSWORD#Security : Sensitive files and programs on a network are password protected (established for specific directories to restrict access to authorized users) or designated as "copy inhibit" so that you do not have to worry about illegal copying of programs.Shared programs, on a network allows for easier upgrading of the program on one single file server, instead of upgradfing individual workstations. Networkable versions are available at considerable saving. Cost : Individually licensed copies of many popular software programs can be costly.Thus saving time, while maintaining the integrity of the file. Speed : Sharing and transferring files within Networks are vary rapid.Wide Area Network (WAN) A WAN is a data communications network that covers a relatively broad geograpghic area and that often uses transmission facilities provided by common carriers, such as telephone companies.Īdvantages and Disadvantages of Network? Advantage of Network Multiple routers, switches & hubs are connected to create a MAN. ![]() Metropolitan Area Network (MAN) A network that connects two or more Local Area Networks together but does not extended beyond the boundaries of the immediate town, city, or metropolitan area is a metropolitan area network. A workgroup is a group of computers that share a common set of resources within a LAN. Local area networks are sometimes called a single location network.įor administrative purposes, large LANs are generally divided into smaller logical segments called workgroups. Local Area Network (LAN) A network that is limited to a relatively small spatial area such as a room, a single building, is called a local area network. Personal area networks may be wired with computer buses such as USB A wireless personal area network (WPAN) can also be made possible with network technologies such as IrDA and Bluetooth. PANs can be used for communication among the personal devices themselves or for connecting to a higher level network and the Internet. The reach of a PAN is typically a few meters. Personal Area Network (PAN) A personal area network (PAN) is a computer network used for communication among computer devices (including telephones and personal digital assistants) close to one person. ![]() Types of Network Below is a list of the most common types of computer networks. This type of network is useful for transferring information between two computers that are not normally connected to each other by a permanent network connection or for basic home networking applications. Internet is also a type of computer network which connects all the computers of the world having Internet facility on them.Ī Simple computer network may be constructed from two computers by adding a network adapter (Network Interface Controller ) to each computer and then connecting them together with a special cable called a crossover cable. A computer network may be described as the interconnection of two or more computers that may share files and folders, applications, or resources like printers, scanners, webcams etc. A computer network is multiple computers connected together using a telecommunication system for the purpose of communicating and sharing resources. ![]()
