A KS3/4 presentation of MAC/IP

1. MAC/IP
Media Access Control/Internet Protocol

2. TCP/IP
 Transmission Control Protocol/Internet Protocol
 AKA Internet Protocol Suite
 Describes how data is sent across the internet

3. TCP/IP
 Application Layer
 data sent by applications to
other applications (e.g. HTTP
in browsers)
 Transport Layer
 process to process
communication.
 Internet Layer
 Transmitting data across
network boundaries
 Link Layer
 Transmission over physical
media (Ethernet/LAN)

4. IP
 Internet Protocol
 Contained within the Internet Layer
 Large set of rules governing communication across
network boundaries
 Two versions currently in use.

5. IPv4/IPv6

6. IPv4 Addressing
 32 bit = 4 bytes
 Each byte separated
by a dot
255
168
10
5

7. IPv6 Addressing
 Much longer address –
uses hex.
2001
0d18
85a1
0000
 Colon(:) separated
0000
8ae2
0318
6831
 Each section is 2 bytes
or 16 bits

8. MAC
 Media Access Control
 Link layer protocol
 Controls access to physical media such as network cards

9. MAC Addressing
 Unique
 48 bit binary address
0A
14
FF
32
11
23
 Expressed in hex in 6
bytes
 Separated by
dashes(-) or
colons(:)
