Computer networking in hindi notes10/29/2022 ![]() ![]() All computers in the peer-to-peer network has equal responsibilities and capabilities to use the resources available on the network. COMPUTER NETWORKING IN HINDI NOTES PCA PC can access files located on another PC and can also provide files to other PCs. Network architecture Peer-to-peer or P2P is a network with all the nodes acting as both servers and clients. A client is a computer which requests services or files from a server computer. A server is a computer that shares information and resources with other computers on a network. Network architecture CLIENT/SERVER NETWORK A client/server network is a network in which the shared files and applications are stored in the server but network users (clients) can still store files on their individual PCs. also known as network model or network design. mainly focuses on the functions of the networks. Network architecture overall design of a computer network that describes how a computer network is configured and what strategies are being used. LEARNING OUTCOMES Networks Architecture Define two types of network architecture i) Client/Server ii) Peer-to-Peer WAN is a group of MANs or LANs or the mixture of both networks. International banks also use WAN to connect their computers all over the world. EG: Local banks have always maintained their business online by connecting all computers of their branches in the countries. WAN generally covers large distances such as states, countries or continents. Internet is the largest WAN in the world. ![]() WIDE AREA NETWORK (WAN) The largest network of all network types. MAN can be defined as a group of computers and network devices connected together within a large physical area. often acts as a high speed network (although not as fast as a LAN) to allow sharing of regional resources. can be a collection of several LANs within the same city. setting up a MAN across long distances can be best connected using fiber optics. Companies that have several branches within the Kuala Lumpur city such as banks, use a MAN. located at different sites within a large physical area, such as a city. METROPOLITAN AREA NETWORK (MAN) ‘ Metropolitan' - describes important cities such as Kuala Lumpur, Manila, Singapore, Tokyo, London and New York. A network which consists of less than 500 interconnected devices across several buildings, is still recognised as a LAN. LAN is operated within a limited physical area, such as at home, school, a single building or several buildings. The simplest form of LAN is to connect two computers together. LOCAL AREA NETWORK (LAN) smallest network compared to the other two networks. TYPES OF NETWORKS LOCAL AREA NETWORK METROPOLITAN AREA NETWORK WIDE AREA NETWORK LEARNING OUTCOMES Types of Networks Define types of computer networks (LAN, MAN, WAN) Differentiate between the three types of computer networks. Cite examples in immediate environment to show the importance of network and communication. The older forms of communications technology, such as telephones and radios, use analog signals. Computers communicate with digital signals. ![]() Ĭomputer network communication We transmit information or data by using two types of signals, namely analog and digital. Communication is an act of transmitting messages. Ĭommunications Communications is about the transfer of information from a sender, across a distance, to a receiver. For example, it may connect computers, printers, scanners and cameras. Ĭomputer network A computer network is a system of interconnected computers and peripheral devices. Define types of computer networks Differentiate between the three types of computer networks. LEARNING OUTCOMES Define computer network Define communications State the importance of computer networks and communications.
