LAN

LAN

1. Hub/Switch/Router

   • a network hub is used for a private network, one that does not have any connections to sources other than local computers (meaning, no Internet access)
   • When a switch receives a packet of data, it determines what computer or device the packet is intended for and sends it to that computer only
   • A router is quite common to find in homes and businesses since it allows your network to communicate with other networks including the Internet

2. devices

   • Ethernet hub
   • Network switch
   • Modems
   • Routers
   • Network Bridges

3. Network Adapter

   • A computer needs a network adapter to connect to a network
   • a computer hardware component that connects a computer to a computer network

4. Network Medium.

   • Wired networks need cable

5. Cable Connectors

   • Making Ethernet cables is easy with a box of bulk Category 5e Ethernet cable and RJ-45 connectors that are attached to the cut ends of your preferred cable length. (You may also use Category 6 or CAT6 cabling which has higher performance specifications and is about 20% more expensive than CAT5e.)
   • The most frequently used type of cable used to connecting a LAN is 4 twisted pair un-shielded cable, often referred to as Ethernet cable

6. Power Supply

   • LAN Power Supply is a dual 2A supervised power supply producing 4A split equally between system power and dedicated battery charging
   • connects to the Concept system LAN, communicating supply status
   • Ganged LAN power supplies come into their own in installations where rapid charging of large back up battery banks is necessary

7. Network Software

   • sends notifications about connection problems
   • keep track of your entire local network, including your workstations, routers, switches and servers or printers

8. LAN Phone

   • one LAN can be connected to other LANs over any distance via telephone lines and radio waves
   • also known as land line, land-line, main line, home phone, landline, fixed-line, and wireline

9. Personal Area Network (PAN)

10. Local Area Network (LAN)

11. Wireless Local Area Network (WLAN)

12. Campus Area Network (CAN)

13. Metropolitan Area Network (MAN)

14. Wide Area Network (WAN)

15. Storage-Area Network (SAN)

16. Disadvantages of a lan is security when using wireless router, most people dont konw how to encrypt their network

17. Advantages of a WAN, Wans are more used by banks, telecommunication providers, and call centres and so on
