Computer Networks
Two very common types of networks
                     Network        LAN: Local Area Network
                                    WAN: Wide Area Network
                 LAN          WAN
Two very common types of networks
       Other types of networks include:
        Metropolitan Area Network (MAN)
        Wireless LAN (WLAN)
        Storage Area Network (SAN)
                              Network Address
Two Type of in Computer Networks
1. Internet Protocol(IP)
          Two Types of IP:
           IPv4: Internet Protocol version 4
                              • IPv4 Length: 32 bits
           IPv6: Internet Protocol version 6
                              • IPv6 Length: 128 bits
IP Address: 32 bit
Example: 192.168.1.1          192.168.1.111000000.10101000.00000001.00000001
          IP Address
                    PCRUNCMD
                                        ipconfig
2. Physical Address/MAC Address
          MAC (Media Access Control) is A Unique Identifier
           48bits Hexadecimal Address
           Ex. 00:0a:95:9d:68:16
           First Three Octets are Manufacturers ID
                    •Dell: 00-14-22
                    •Cisco: 00-40-96
Host name, IP & MAC Address
                    PCRUNCMD
                                        ipconfig /all
LAN: Local Area Network
LAN: Local Area Network
 Computer Network configuration
 Connectivity Test : ping(Packet Internet Groper ) command
             PC command:
             Ifconfig
             Ifconfig /all
             Ping
