Service Provider An ISP is a business that provides connectivity to the Internet for individuals and other businesses or organizations Local Area Network A network of end stations such as PCs printers servers and network devices hubs and switches that cover a relatively small geographic area usually not larger than a floor or building LANs are characterized by high transmission speeds over short distances up to 1000 metres Media Access Control A protocol specified by the IEEE for determining which devices have access to a network at any one time Media Access Control Address Also called the hardware or physical address A layer 2 address associated with a particular network device Most devices that connect to a LAN have a MAC address assigned to them as they are used to identify other devices in a network MAC addresses are 6 bytes long Network Address Translation NAT enables all the computers on your network to share one IP address The NAT capability of the Router allows you to access the Internet from any computer on your home network without having to purchase more IP addresses from your ISP A Network is a collection of computers and other computer equipment that are connected for the purpose of exchanging information or sharing resources Networks vary in size some are within a single room others span continents A circuit board installed into a piece of computing equipment for example a computer that enables
19. Static Addressing m Automatic Addressing Auto IP Addressing The Router contains a DHCP server which allows computers on your network to obtain an IP address and subnet mask automatically DHCP assigns a temporary IP address and subnet mask which gets reallocated once you disconnect from the network DHCP will work on any client Operating System such as Windows 95 Windows 98 or Windows NT 4 0 Also using DHCP means that the same IP address and subnet mask will never be duplicated for devices on the network DHCP is particularly useful for networks with large numbers of users on them You must enter an IP Address and the subnet mask manually on every device Using a static IP and subnet mask means the address is permanently fixed 106 APPENDIX B IP ADDRESSING Auto IP Addressing Network devices use automatic IP addressing if they are configured to acquire an address using DHCP but are unable to contact a DHCP server Automatic IP addressing is a scheme where devices allocate themselves an IP address at random from the industry standard subnet of 169 254 x x with a subnet mask of 255 255 0 0 If two devices allocate themselves the same address the conflict is detected and one of the devices allocates itself a new address Automatic IP addressing support was introduced by Microsoft in the Windows 98 operating system and is also supported in Windows 2000 C SAFETY INFORMATION Important Safety Information gt EEE
