A computer network, or simply a network, is a collection of computer and other hardware components interconnected by communication channels that allow sharing of resources and information. Where at least one process in one device is able to send/receive data to/from at least one process residing in a remote device, then the two devices are said to be in a network. Simply, more than one computer interconnected through a communication medium for information interchange is called a computer network.
Basic idea about router. Router configuration. This is our team project. From this slide we can learn what is router configuration and application of router. We also learn the security of router.
One way to categorize the different types of computer network designs is by their scope or scale. For historical reasons, the networking industry refers to nearly every type of design as some kind of area network. Common types of area networks are:
LAN - Local Area Network
WAN - Wide Area Network
WLAN - Wireless Local Area Network
MAN - Metropolitan Area Network
SAN - Storage Area Network, System Area Network, Server Area Network, or sometimes Small Area Network
CAN - Campus Area Network, Controller Area Network, or sometimes Cluster Area Network
PAN - Personal Area Network
LAN and WAN are the two primary and best-known categories of area networks, while the others have emerged with technology advances

Experimental analysis of channel interference in ad hoc networkijcsa
In recent times, the use of ad hoc networks is a common research area among a researcher. Designing an
efficient and reliable network is not easy task. Network engineer faces many problems at the time of
deploying a network such as interference; Signal coverage, proper location of access point etc. channel
interference in one of them which must be considered at the time of deploying WLAN indoor environments
because channel interference impacts the network throughput and degrade the network performance.
In this experiment, we design a two WLAN BSS1 and BSS2 and investigate the impact of interference on
nodes. BSS1 contains three FTP clients and BSS2 contains two FTP client and their jobs is to upload data
to FTP Server Initially, they are far from each other. BSS1 moves toward BSS2 and after some time at
particular position both BSSs overlaps to each other. When BSSs overlaps to each other interference is
high and decrease network performance and increase upload time.

Wireless communication involves the transmission of information over a distance without the help of wires, cables or any other forms of electrical conductors.
Wireless communication is a broad term that incorporates all procedures and forms of connecting and communicating between two or more devices using a wireless signal through wireless communication technologies and devices.
Features of Wireless Communication
The evolution of wireless technology has brought many advancements with its effective features.
The transmitted distance can be anywhere between a few meters (for example, a television's remote control) and thousands of kilometers (for example, radio communication).
Wireless communication can be used for cellular telephony, wireless access to the internet, wireless home networking, and so on.

11. LAN, MAN & WAN
Introduction to Computer Networks
Network in small geographical Area (Room, Building
or a Campus) is called LAN (Local Area Network)
Network in a City is call MAN (Metropolitan Area
Network)
Network spread geographically (Country or across
Globe) is called WAN (Wide Area Network)
12. Applications of Networks
Introduction to Computer Networks
Resource Sharing
Hardware (computing resources, disks, printers)
Software (application software)
Information Sharing
Easy accessibility from anywhere (files, databases)
Search Capability (WWW)
Communication
Email
Message broadcast
Remote computing
Distributed processing (GRID Computing)
13. Network Topology
The network topology
defines the way in
which computers,
printers, and other
devices are connected.
A network topology
describes the layout of
the wire and devices as
well as the paths used
by data transmissions.
Introduction to Computer Networks
14. Bus Topology
Commonly referred to
as a linear bus, all the
devices on a bus
topology are connected
by one single cable.
Introduction to Computer Networks
15. Star & Tree Topology
Introduction to Computer Networks
The star topology is the most
commonly used architecture in
Ethernet LANs.
When installed, the star
topology resembles spokes in
a bicycle wheel.
Larger networks use the
extended star topology also
called tree topology. When
used with network devices that
filter frames or packets, like
bridges, switches, and routers,
this topology significantly
reduces the traffic on the wires
by sending packets only to the
wires of the destination host.
16. Ring Topology
Introduction to Computer Networks
A frame travels around the ring,
stopping at each node. If a node
wants to transmit data, it adds the
data as well as the destination
address to the frame.
The frame then continues around
the ring until it finds the
destination node, which takes the
data out of the frame.
Single ring – All the devices on
the network share a single cable
Dual ring – The dual ring topology
allows data to be sent in both
directions.
17. Mesh Topology
The mesh topology
connects all devices
(nodes) to each other
for redundancy and
fault tolerance.
It is used in WANs to
interconnect LANs and
for mission critical
networks like those
used by banks and
financial institutions.
Implementing the mesh
topology is expensive
and difficult.
Introduction to Computer Networks
19. Networking Media
Networking media can
be defined simply as
the means by which
signals (data) are sent
from one computer to
another (either by cable
or wireless means).
Introduction to Computer Networks
21. Computers: Clients and Servers
In a client/server
network arrangement,
network services are
located in a dedicated
computer whose only
function is to respond
to the requests of
clients.
The server contains the
file, print, application,
security, and other
services in a central
computer that is
continuously available
to respond to client
requests.
