The document discusses the client-server model. It defines a client as a computer or program that requests services from a server. A server provides services or resources to clients. The client-server model describes a distributed computing relationship where clients communicate with servers over a network like the internet or local area network. There are different types of clients like thick, thin, and hybrid clients. Common client-server architectures include 2-tier and 3-tier architectures. The client-server model provides advantages like easy maintenance and backup/recovery but also disadvantages like potential traffic congestion and high costs.

4. Introduction
With the advancement in technology, Web is becoming very much
more important in our daily lives, in which virtually everything we
do nowadays involves the use of web. More so, the application of
Web is not limited to computers but it is opened to different kinds
of intelligent digital devices, for example the mobile ones.

5. What Is Client
 Clients are also referred to as service requester
 Thick Client-. It depends very less on the server.
 Thin Client- A thin client refers to a lightweight computer which
depends on the resources of the host computer to a great extent.
 Hybrid Client- A hybrid client is a combination of a thick client’s
and a thin client’s characteristics. It mostly depends on the server
for storing persistent data. It is capable of local processing

6. What Is Server
A server is a computer program or device that provides a
service to another computer program and its user, also
known as the client. In a data center, the physical computer
that a server program runs on is also frequently referred to
as a server

7. Client Server Model
 The client server model describe distributed computing
relationship between at least two independent computer ( a
client and server) which communicate through the internet or
local area network.
 There can be multiple client on each server
 Example of using he client/server include bank account
transaction

8. Client Server Network
 A client-server network refers to the medium that enables clients
to access resource and services from a central computer by using
either the LAN (Local Area Network) or the WAN (Wide Area
Network).
 The most popular network services are, e-mail, file sharing and
the World Wide Web.

9. Client server Architecture
client-server architecture, architecture of a computer network in
which many clients request and receive service from a server .
Client computers provide an interface to allow a computer user to
request services of the server and to display the results the server
returns.
The two main architectures :
2- tier architecture
3- tier architecture

10. 2-Tier Architecture
In a two-tier architecture, the client is on the first tier and
database server is on the second tier.

11. 3-Tier Architecture
In a three-tier architecture, the client is on the first tier and
application server is on the second tier and database server
is on the third tier

12. Peer To Peer Network
A peer to peer networks involves two or more computer that share
individual resources, including DVD players, printer . Each
computer in the network act as client as well as the server.
communicating with the other computer directly.

13. Advantages
Easy maintenance: New technology can be added easily through the
server. Server resources can be decreased or increased depending upon the
client request. If any server computer needs to take backup of its data then
control can be shifted to another server. The data backup can be taken at a
time when there are fewer requests to the server.
Dedicated server: A server can be either a file server, print server or
database server.
Backup and recovery: Taking backup of data and recovering data
is easy.
Accessibility: A server can be accessed remotely through multiple
platforms.

14. Disadvantages
1. Traffic Congestion:- The primary disadvantage of client server network is
the traffic congestion it undergoes. If too many clients make request from the
same server, it will result in crashes or slowing down of the connection. An
overloaded server creates many problems in accessing information .
2. Cost:- the cost involved in setting up and maintaining the server is usually high
in client server network as it does on the network operations.
3. Maintenance:- When the servers are implemented, it is going to work non-
stop. Which means it must be given proper attention. If there are any problems, it
must be resolved immediately without any delay.
4. Resources:- Not all the resources that is present on the server is
acquirable. For an example, it is not possible to print a document on the
web directly or edit any information on the client hard disk drive.

15. Conclusion
In conclusion, the client-server system encompasses different
areas both in networking and database management due to its
structural functionalities, it is essential to know that the advent
of the technology is a breakthrough in the IT world and also in
the business world because without the application of this
technology, work process would be difficult to execute and might
take longer time
