Connectivity of two or more than two devices so that they can
communicate to exchange resources and share information is called
a Network .
3. Introduction- [Netwrok]
3
• A network is a combination of hardware and software that sends
data from one location to another.
• The hardware consists of the physical equipment that carries
signals from one point of the network to another.
• The software consists of instruction sets that make possible the
services that we expect from a network.
6. Introduction- [Wired Netwrok]
6
Wired technology is more associated with wired communication.
Wired communication refers to the transmission of data over a wire-
based communication technology.
7. Introduction- [Wireless Netwrok]
7
The term wireless refers to the communication of information over a
distance, without requiring wires, cables or electrical conductors.
8. Introduction- [Internetwork]
8
• An internetwork can be defined as two or more computer networks
which are connected together, using Network Routers.
• Each network in an Internetwork has its own Network Address,
which is different from other networks inside the Internetwork.
• Internetwork allows different users at different geographical
locations of an organization to share data, resources and to
communicate
9. Introduction- [Internetwork]
9
Type of Internetwork:
1. Internet: Internet is a worldwide, publicly accessible computer
network of interconnected computer network.
2. Intranet: An intranet is a private network that is contained
within an enterprise.
10. Introduction- [Internetwork]
10
Type of Internetwork:
3. Extranet: An extranet can be viewed as part of a company's
intranet that is extended to users outside the company like
suppliers, vendors, partners, customers, or other business
associates.

18. [Architecture]→ Peer to Peer (Work Group)
18
A peer-to-peer (P2P) network is group of computers, each of which
acts as a node for sharing files within the group.
19. [Architecture]→ Server Based (Client / Server)
19
A Server-based network is a network in which network security and
storage are managed centrally by one or more servers.

21. [Topology]→ Bus Technology
21
A bus network is an arrangement in a
local area network (LAN) in which
each node (workstation or other
device) is connected to a main cable or
link called the bus.
22. [Topology]→ Ring Technology
22
A ring network is a local area network
(LAN) in which the nodes (workstations
or other devices) are connected in a
closed loop configuration.
23. [Topology]→ Star Technology
23
A star network is a local area network
(LAN) in which all nodes (workstations
or other devices) are directly connected
to a common central computer.
24. [Topology]→ Mesh Technology
24
The mesh network topology links nodes
with connections so that multiple paths
between at least some points of the
network are available.
The Internet is a mesh network.
25. [Topology]→ Tree Technology
25
The tree network topology, also
called a star of stars, is a network
where star topologies are
themselves connected in a star
configuration.
33. [Netwrok]→ Network Devices
33
Network devices, or networking hardware, are physical devices that
are required for communication and interaction between hardware
on a computer network.
35. [Network Devices]→ Passive
35
Passive Networking Hardware are those parts of computer network
that are involved in data transmission in the network, but they don’t
change or affect the data.
Passive networking components are an essential part of any computer
network.
37. [Network Devices]→ Active
37
Active Networking Hardware comprises the parts of a computer
network that in some way actively work with signals in the network.
47. [Netwrok] → Transmission Modes
47
Transmission mode means transferring of data between two
devices. It is also known as communication mode.
There are three types of transmission mode:-
1. Simplex Mode
2. Half Duplex Mode
3. Full Duplex Mode
48. [Transmission Modes] → Simplex Mode
48
In Simplex mode, the communication is unidirectional, as on a
one-way street. Only one of the two devices on a link can transmit,
the other can only receive. The simplex mode can use the entire
capacity of the channel to send data in one direction.
