Basic concepts of computer Networking • 1. The empire 7th edition army book pdf. Basic Concepts of ComputerNetworks and Communications Network Topology Presented by- Company Hassan Jan Habib LOGO BS (1st Semester) • Presentation Contents Definition of Computer Networks Different Network Methods LAN Network Topologies Summary • Computer NetworksDefinition: Computer networking is the engineering decipline concerned with the communication between computer systems or devices. A computer network is any set of computers or devices connected to each other with the ability to exchange data. • Different Network MethodsDifferent Network Methods are: Local area network (LAN), Metropolitan area network (MAN) Wide area network (WAN) Wireless LANs and WANs • Local Area Network (LAN)Local Area Network(LAN), which is usually a small network constrained to a small geographic area.
An example of a LAN would be a computer network within a building. • DEFINITION What is a Topology? The physical topology of a networkrefers to the configuration of cables, computers and other peripherals.
• TYPES OF NETWORK TOPOLOGYThree commonly used network topologiesare:- Bus Topology Ring Topology Star Topology • BUS TOPOLOGYAll computers and devicesconnected to central cable or bus.Consists of a main run of cablewith a terminator at each end.Popular on LANs because theyare inexpensive and easy toinstall. • BUS TOPOLOGY • RING TOPOLOGYCable forms closed ring or loop,with all computers and devicesarranged along ring.Data travels from device todevice around entire ring, inone direction.Primarily is used for LANs,but also is used in WANs. • RING TOPOLOGY • STAR TOPOLOGYAll devices connect to acentral device, calledhub.All data transferredfrom one computer toanother passes throughhub.
• STAR TOPOLOGY • STAR TOPOLOGY • MESH TOPOLOGY In the mesh topology each computer are connected with each other by separate cable. Create point to point connection to every device on network.

If one cable fail data always has alternative path to get to its destination. On a large scale, you can connect multiple LANs using mesh topology with leased line.
