1. What is computer networking?
Ans: Computer Networking means a
collection of interconnected autonomous
computer that are equipped to exchange
information and share resources with each
other.
a. What’s a server: A computer that
manages all the resources and services on
a computer network is called a server.
b. What’s a workstation: any computer
connected to a server is a workstation.

4. Types of Network?
Local Area Network (LAN): A LAN is a
network that connects devices within a
limited geographical area, such as a home,
office building, or school campus.
Metropolitan Area Network (MAN): A
MAN is a network that covers a larger
geographical area than a LAN but is smaller
than a WAN, typically serving a city or
metropolitan area.
Wireless LAN (WLAN): A WLAN is a type of
LAN that uses wireless communication
technology, such as Wi-Fi, to connect
devices instead of Ethernet cables
Virtual Private Network (VPN): A VPN is a
secure network that allows users to access
resources and communicate over a public
network, such as the internet, as if they
were directly connected to a private
network.
A Personal Area Network (PAN) is a type
of network used for connecting devices
within a small, personal space. Unlike
larger networks like LANs or WANs, PANs
typically cover areas of a few meters and
are designed for personal use.
5. What’s an Internet:
The internet is a global system of
interconnected computer networks that
allows devices all over the world to
communicate with each other.
6. How a Network Works?
A network functions like a complex
communication system, allowing devices
to connect, share information, and access
resources by following established
protocols and utilizing specific hardware
and software components. A protocol is a
set of standardized rules and guidelines
that govern how devices communicate and
exchange data. It's like a common
language that allows different devices and
software to understand each other,
enabling them to exchange information
effectively. Most commonly used protocols
are as follows:
• Internet Protocol (IP)
• Transmission Control Protocol (TCP)
It's a protocol suite (a set of related
protocols) that lays out the foundation for
how devices communicate across the
internet and many other types of
networks.
SMTP stands for Simple Mail Transfer
Protocol. It's a communication protocol
used specifically for sending and receiving
email messages between email servers
POP3 stands for Post Office Protocol
version 3. It's a retrieval protocol used by
email clients to download and manage
email messages from a mail server
IMAP stands for Internet Message Access
Protocol. It's a retrieval protocol used by
email clients to access and manage email
messages on a mail server.
