  1. 1. M.P.V.VALIA COLLEGE OF COMMERCE  NAME : Narechania Darshit STD : T.Y.B.COM DIV : B ROLL NO : 205 1
  2. 2. INDEX  2
  3. 3. Presented by: Darshit Narechania 3
  4. 4. Computer Network:   A network consists of two or more computers that are linked in order to share resources, exchange files, or allow electronic communications.  The computers on a network may be linked through cables, telephone lines, radio waves, satellites, or infrared light beams 4
  5. 5. Need of Computer Network:   File sharing  Resource sharing  Communication and collaboration  Remote access  Data protection 5
  6. 6. Devices Use To Connect Network:   Routers  Gateways  Repeaters  Bridges  Hub  Modem 6
  7. 7. Types Of Network:   Local Area Network  Wide Area Network  Metropolitan Area Network 7
  8. 8. Local Area Network:   A local area network (LAN) is a group of computers and associated devices that share a common communications line or wireless link.  Typically, connected devices share the resources of a single processor or server within a small geographic area .  . A local area network may serve as few as two or three users or as many as thousands of users. 8
  9. 9. 9
  10. 10. Wide Area Network:   The WAN is a communications network that makes use of existing technology to connect local computer networks into a larger working network that may cover both national and international locations. 10
  11. 11. 11
  12. 12. Metropolitan Area Network (MAN):   A metropolitan area network (MAN) is a network that interconnects users with computer resources in a geographic area or region larger than that covered by even a large local area network but smaller than the area covered by a wide area network (WAN).  It is also used to mean the interconnection of several local area networks by bridging them with backbone lines 12
  13. 13. Network Topologies   Network Topology – Maps of how the physical or logical paths of network devices connect. The three major topologies are star, ring, and bus.  Star Topology – Most common Ethernet network topology where each device connects to a central hub or switch.  Hub – A device used with the Universal Serial Bus or in a star network topology that allows multiple device connections.  Switch – In star networks, a Layer 2 central controlling device. A switch looks at each data frame as it comes through each port.  Ring Topology – Network that is physically wired like a star network but, logically in a ring; passes control from one device to the next in a continuous fashion using a special data packet called a token. Used in Token Ring networks.  Bus Topology – Network wherein all devices connect to a single cable. If the cable fails, the network is down.  Mesh Topology – Network where all devices connect to each other by cabling to provide link redundancy for maximum fault tolerance. Most likely in WANs. 13
