- 4. NETWORK Two or more communication devices are connected together then we call this setup as a network. If these connected devices are started communicating then we call this setup as a Networking E.g. television, telephone, computer
- 5. COMPUTER NETWORK Computer network connects two or more device together to share information and services, such as Documents ,Music, Databases, Video conferencing etc Application: • Sharing of resources
- 6. TYPES OF NETWORK There major types of networking : LAN WAN MAN Other types of networking: – PAN – CAN
- 7. LOCAL AREA NETWORK • LAN is a network which is designed to operate over a small physical area such as office, factory or a group of buildings • LAN’s are easy to design and troubleshoot. • Exchange of information and sharing of resources becomes easy because of LAN. • In LAN all machines are connected to a single cable. • Different types of topologies such as star, tree, bus, ring, etc Can be used
- 8. WIDE AREA NETWORK A WAN is a network of computers over a large geographical area, such as across a country or the world. Examples • The Internet • Companies like the BBC communicating across the world Uses • video-conferencing, use of e-mail, live chat • Sharing Information - access to databases, • E-commerce and entertainment Transmission Media • Fibre Optic, Microwave transmission and Satellite
- 9. METROPOLITAN AREA NETWORK • It is in between LAN & WAN technology that covers the entire city. • It uses similar technology as LAN. • It can be a single network such as cable TV network, or a measure of connecting a number of LAN’s or a large network so that resources can be shared LAN to LAN as well as device to device
- 10. PERSONAL AREA NETWORKS •A personal area network (PAN) is a computer network used for communication among computer and different information technological devices •Is a small network established for communication between different devices such as laptops,computers, mobiles, and PDAs. •A pan may include wired and wireless devices. •The reach of a pan typically extends to 10 meters.
- 11. CAMPUS AREA NETWORK A campus area network is a computer network made upof an interconnection of local area networks (LANs) within a limited geographical area. The networking equipments (switches, routers) and transmission media (optical fiber, copper plant, Cat5 cabling etc) are almost entirely owned by the campus owner: an enterprise, university, government etc.
- 12. TYPES OF NETWORK
- 13. Transmission Mode Simplex – uni-direction communication Half Duplex – At a Time one Direction communication Full Duplex – At a Time both Direction
- 14. Network Components NIC card(Network interface card) NIC is used to connect computer to an Ethernet Network Protocols Protocols are rules that govern how devices communicate share information across a network Eg: SMTP , POP3 Cable Cable is the medium through which information usually moves from one network to another
- 15. ETHERNET TECHNOLOGIES Ethernet is a network technology invented to connect network devices together Ethernet is a popular packet switching LAN Technology invented by Xerox in 1970s, and operated at 2.94Mbps. • 10 Mbps-10Base-T Ethernet • 100 Mbps-Fast Ethernet -100 Base-T • 1000 Mbps-Gigabit Ethernet 1000 Base-T
- 16. ETHERNET CABLING Cable is a medium through which information usually moves from one network to another Cables Coaxial Twisted pair optical fiber Thinnet Thicket shielded Unshielded Single mode Multimode Coaxial cables: It consist of single wire surrounded by insulation, as Metallic and a plastic shield Thicket - wider diameter Thinner - having smaller diameter
- 17. ETHERNET CABLING Twisted Pair Cable Four pair of copper wire in a plastic sheath A pair of wires are twisted together Twisted pair cable is the most common Ethernet cable Unshielded Twisted pair Cat 5(100Mbps),Cat 5e(100Mbps), Cat 6(1Gb), Cat 6E(1Gb) Fiber optics are uses light to transmit signal Single mode require more precise electronic than multimode Multimode is more high in speed compared to Single mode
- 18. CRIMPING COMPONENTS • Crimping tool • Connectors(rj-45) • Cable checker • Cables Cat 5 (100Mbps),Cat 5e(100Mbps), Cat 6(1Gbps),Cat 6e(1Gbps)
- 19. CONNECTION TYPE Straight through Connection – it used to connect different devices in networking Eg: Pc to Switch ,Pc to Modem, Switch to Router , Switch to modem
- 20. CONNECTION TYPE Cross over it is used to connect same devices in networking Eg: switch to switch ,pc to pc
- 21. CONNECTION TYPE Role over it is used to configure devices in networking Eg: pc to router
- 22. PHYSICAL COMPONENTS OF NETWORK
- 23. COMMANDS Ipconfig It allow us to know IP address It allow us to know subnet mask It allow us to know Default Gateway ping It is used for test Network Connectivity Eg: ping ip address
