Computer networks share common devices, functions, and choices further as servers, clients, transmission media, shared data, shared printers and totally different hardware and package resources, network interface card(NIC), native operating system(LOS), and thus the network operating system(NOS).
Servers - Servers area unit computers that hold shared files, programs, and thus the network code package. Servers provide access to network resources to any or all the users of the network. There area unit many various kinds of servers, and one server can provide several functions. as associate degree example, there area unit file servers, print servers, mail servers, communication servers, info servers, print servers, fax servers and web servers, to decision several.
Clients - shoppers area unit computers that access and use the network and shared network resources. shopper computers area unit basically the customers(users) of the network, as they request and receive services from the servers.
Transmission Media - Transmission media area unit the facilities accustomed interconnect computers terribly} very network, like twisted-pair wire, coax cable, and glass fibre cable. Transmission media area unit usually called channels, links or lines.
Shared data - Shared data area unit data that file servers provide to shoppers like data files, printer access programs and e-mail.
Shared printers and totally different peripherals - Shared printers and peripherals area unit hardware resources provided to the users of the network by servers. Resources provided embrace data files, printers, software, or the opposite things utilised by shoppers on the network.
Network Interface Card - each computer terribly} very network includes a special enlargement card called a network interface card(NIC). The NIC prepares(formats) and sends data, receives data, and controls data flow between the computer and thus the network. On the transmit side, the NIC passes frames of data on to the physical layer, that transmits the knowledge to the physical link. On the receiver's side, the NIC processes bits received from the physical layer and processes the message supported its contents.
Local code package - a part code package permits personal computers to access files, print to a part printer, and have and use one or lots of disk and CD drives that area unit placed on the computer. Examples area unit MS-DOS, Unix, Linux, Windows 2000, Windows 98, Windows XP etc.
Network code package - The network code package is also a program that runs on computers and servers, and permits the computers to talk over the network.
Hub - Hub is also a tool that splits a network association into multiple computers. it's variety of a distribution center. once a computer request information from a network or a specific computer, it sends the request to the hub through a cable. The hub will receive the request and transmit it to the entire network. each computer at intervals the network got to then verify whether or not or not the printed data is for them or not.
Switch - Switch is also a telecommunication device classified joined of system parts. Switch is variety of a Hub but in-built with advanced choices. It uses physical device addresses in each incoming messages therefore it'll deliver the message to the right destination or port.
Like Hub, switch don’t broadcast the received message to entire network, rather before inflicting it checks to it system or port got to the message be sent. in several words switch connects the provision and destination directly that may increase the speed of the network. every switch and hub have common features: Multiple RJ-45 ports, power supply and association lights.
Servers - Servers area unit computers that hold shared files, programs, and thus the network code package. Servers provide access to network resources to any or all the users of the network. There area unit many various kinds of servers, and one server can provide several functions. as associate degree example, there area unit file servers, print servers, mail servers, communication servers, info servers, print servers, fax servers and web servers, to decision several.
