The document discusses Internet Protocol (IP) and Transmission Control Protocol (TCP). It explains that IP allows data packets to be addressed and routed through a network without a direct link between sender and receiver. TCP is a set of rules that defines how computers address and send data to each other. The purpose of IP is to define the basic unit of data transfer (datagram) and perform routing functions. Each datagram contains a header and data. IP addresses uniquely identify devices on the internet and are expressed in decimal format for human readability.

2. What is IP/TCP?
• IP itself is like a postal system
• IP stands for Internet protocol
• It allows you to address a package and
drop it in the system, but there is no direct
link between sender and receiver
• Protocol is the pre-defined way that
someone wants to use a service talk with
that service. The “someone” could be a
person but usually it is a computer server or
web browser

3. Basically…
• In simple terms is a language that
enables communication between
computers
• A set of rules (protocol) that defines how
two computers address each other and
send data to each other
• Is a suite of protocols named after the
two most important protocols TCP and
IP but includes other protocols such as
UDP, RTP, etc.

4. Purpose Of IP
• The Internet protocol defines the
basic unit of data transfer(IP
DATAGRAM)
• IP software performs the routing
function

5. Datagrams
Each datagram has two components
Header Data
Packets (Datagrams)

6. • Need a standard needs of communication
between devices
• Can’t communicate if speaking two
different languages
• Therefore we have a concept called
“Protocol”

9. IP service
IP supports the following services
• Unicast
• Broadcast
• multicast

10. IP address
Every machine on the internet has unique identifier
number, called an IP address.
A typical address looks like 217.27.61.741
To make it easier for us humans to remember , IP
address are usually expressed in decimal
Format as dotted decimal number like the one above,
but computer communicates in binary form
