Clients and Servers

Clients and Servers :

The client server model is very important relationship in networking filed. There are two terms in these model first one is client and second one is server.This relationship is basically work on request and resonance approach.

1) Client :
 Basically clients role in this relationship is that client  request to server for provide service.there are multiple clients in single network, which  request to server for provide service to them.

2) Server:
 server stands for provide services to client on the bases of request given by clients. now  the thing is what is server? so server is just normal computer system which provide services to other systems that called server.

Example :
When a Locale customer accesses online hotel booking services with a web browser (the client), the client initiates a request to the Hotel web server. The customer's login credentials  are stored in a database, and the web server accesses the database server as a client. An  application server interprets the returned data by applying the hotels's business logic, and  provides the output to the web server. Finally, the web server returns the result to the client  web browser for display.

Metropolitan Area Network

3.)Metropolitan Area Network (MAN) :

Metropolitan area network is a connect a computers in large geographical area by connecting LAN network and create a network for ruler area which is known as Metropolitan Area Network (MAN).

It is basically use for ruler area to connect offices,schools which are in same city for single control and single server provides same services to every LAN network which is connected to server.   

    

What is Network?

NETWORK 

Network is a group of tow or more connected devices.

There are basically three types of Network :

1.) Local area Network (LAN)
2.) Wide area Network(WAN)
3.) Metropolitan area Network ( MAN)

Now what are this types  :

1.) Local area Network (LAN) :

Local area network or LAN is collection of connected computers in limited area such as buildings ,Schools ,offices etc.

It is very useful in corporate,schools for creating their own network.

in this type of network the computers are connected with each other through cable and controlled by router or HUB. router and HUB are connected to server. 

 

LAN s are typically used for single sites where people need to share resources among themselves but not with the rest of the outside world.

Hub is a network  hardware device for connecting multiple lan cable devices together and its work as a single network.

2.) Wide area network (WAN) :

 A Wide area network is a computer Network that can be establish in large geographical area with less cable and circuits.

This type of network is use for connecting different states or country's and work as single network.

World Wide WEB (WWW) is a one type of WAN network. everyone is aware form WWW .

This network type is also useful for University,Business,Bank etc. to create large network for cover their all branches form different states and country.

what is the mening of Information Technology...?

Information Technology is an application  related to computing technology, such as networking, hardware, software, the Internet, or the people that work with these technologies.

In simple words every thing runs on internet,work with internet or connected to internet that is  information technology.

In Other words I.T is provides you one platform that allows you to work dynamically  by seating in one corner through all over the world.

Now a days Information Technology is fastest growing filed in this competitive world to work more easily ,effectively and faster.

As all we use social networking sites like Facebook,twitter etc.. mobile applications are one type of information technology. 

There is so many sub fields in Information Technology such as:

-Networking
-Software engineering
-Hardware and networking
-cloud computing
-Web Developing
-animation etc..
 
I hop i will make you clear about Information Technology.this is my first blog so please write review for me and let me know about my first try .

thank you.
