The tcp/ip model

•The TCP/IP suite is the most common used protocol suite in the networking world

•It is essentially the protocol suite in which the internet was built

•It is the standard for computer networking

•It is based on a 4-layer model that is similar to the OSI Model

Tcp/ip model and suite of protocols

Mac addresses

•Media Access Control (MAC)

•Physical address of the network adapter card

•OSI layer 2 (Data Link) layer address

•TPC/IP network interface layer address

•Six bytes (48 bits), usually represented hexadecimal

•First three bytes (24 bits) are assigned by the IEEE to the manufactured

•OUI (Organizationally Unique Identifier) assigned by IEEE ex: dell, hp

•Last three bytes are usually assigned sequentially

•Allow for uniqueness duplications are rare

•00-24-1D-7C-8D-7C

Determining your mac address

Ipv4 addresses

•Internet protocol version 4 (Logical Address u can setting or change)

•OSI layer 3 (network) address

Determining your ip address

Comparing ip & mac addresses

•Ip addresses

•Network (OSI layer 3) addresses

•Logical addresses

•Allows network to network communication via routers (Distant WAN commutation) (tlp number)

•Dotted decimal notation

        •192.168.100.1

•MAC Addresses

•Data Link (OSI Layer 2) addresses

•Physical Addresses

•Physically burned on NIC

•Allows internetwork communication via hubs switches, and router (Local LAN Communication)

•Home address
