this slide shows ip adderess and network protocols

2.  An IP address, short for Internet Protocol
address, is a unique numerical label
assigned to each device connected to a
computer network that uses the Internet
Protocol for communication. It serves two
main functions: identifying the host or
network interface and providing the location
of the device in the network.

3.  Physical IP Addresses
 A physical IP address
refers to a unique numerical identifier
assigned to a network interface or device
connected to a network.
 It is permanently associated with the
hardware and location of the device.
 Physical IP addresses are typically used for
long-term identification and communication
purposes.

4.  A temporary IP address, also known as a
dynamic IP address, is a temporarily
assigned numerical identifier that changes
periodically.
 Internet Service Providers (ISPs) often
assign temporary IP addresses to devices
when they connect to the internet.

5.  IP addresses are divided into classes based
on their range and the network size they can
support.
 The four classes of IP Addresses and their
range are as follow
 There are 255 total number of IP Addresses

6.  Class A(0-126)
 CLASS B(128-191)
 CLASS C(192-223)
 CLASS D(224-239)
 CLASS E(240-255)

7.  Data communication refers to the process of
transmitting, receiving, and exchanging
digital information between two or more
devices or systems. It involves the transfer
of data or information over a communication
medium, such as cables, wireless
connections, or optical fibers, using various
protocols and technologies.

8.  Sender: The device or system that initiates
the transmission of data. It converts the
information into a suitable format for
transmission.
 Receiver: The device or system that receives
the transmitted data and converts it back into
a usable format for the recipient.

9.  Communication devices in data
communication are hardware devices or
components that enable the transmission,
reception, and processing of data over
communication networks. They include
devices such as routers, switches, modems
etc.
 Transmission: The actual process of sending
the encoded data over the communication
medium. It may involve analog or digital
signals, depending on the type of medium
and modulation technique used

10. Client Server
client is a machine or a
program that requests for
services through the web
a server is a machine or a
program that provides services
to the clients according to the
client’s requests.
Clients initiate communication
by sending requests to
servers and then receive and
process the responses.
It responds to client requests
by processing them and
returning the requested
information or performing the
requested action.
Desktops, laptops,
smartphones, tablets and web
browsers
Database servers, file servers,
and web servers are some
examples for servers.

11.  Networking refers to the practice of
connecting devices and systems to enable
communication, data sharing, and resource
sharing between them. It involves the
design, implementation, management, and
maintenance of networks that facilitate the
exchange of information and services.
