What is a client-server network? How many types and what? How does client server network work?

Client-server network


Usually when we receive any data, the computer from which we receive the data or service is called server. We are clients or consumers because we serve from it. In this network, both workstation and server computers have the opportunity to work autonomously with their own CPU and memory. It consists of a graphical user interface or front end program on the client workstation and other facilities. It stores the back end server programs of one or more servers.


In other words, a suitable network for centrally storing data, ensuring security, running various applications and running the network is a client-server network. In this network, one computer owns the resource, and other computers in the network use those resources. The computer that shares the resource is the server, and the computers that share the resource are the clients. All the resources of the network are stored on the server so the resources can be managed from the center. Security is ensured as all users log into the same server and adhere to the server's security policy.


Characteristics of client-server network: A client-server network is also called a server-based network. Characteristics of client-server network:


(i) Client-server network is easily expandable. This can be done for anything from ten users to thousands of users.

(ii). Such networks consist of servers. Server computer hardware is usually of high quality and these servers provide various services to other computers.

(iii) Client-server network is very secure as it uses user level access control.

(iv) Such networks can be centrally controlled by network administrators.

(v) Users in such networks do not require network management. That is why the skill of the network users is not so important.


Difference between Client Server and Peer to Peer Network:

Peer to peer network

 (i) All computers connected to a network are of the same class or peers and are called peers.

(ii) Computers in this network play the role of both server and client, so no separate server addition is required.

(iii) Ease of design and maintenance of peer to peer networks.

(iv) Cost is lower in peer to peer network.

(v) In peer to peer network security of information cannot be maintained as information is not stored in a central server.


Client Server Network

(i) The central computer used in it is called server and the computers connected to the server are called workstations or clients.

(ii) It requires the addition of one or more servers to the network, whose back-end programs respond to a client.

(iii) Design and maintenance of client server network is relatively complex.

(iv) Cost is relatively high in client server network.

(v) It stores information on central servers and ensures security of information from authorized users.

What should the processor look at?

The things that we all should keep an eye on are the processor or not; 1. Clock speed 2. Number of course 3. cache memory 4. FBS 1. Clock Speed: It is also called GH2. All processors are written on. Clock speed means how fast your computer can work. That's what this signal means. The speed of the processor is known through this clock speed, how fast the calculation can be done. 2. Number of Cores: The more cores the processor has, the faster the processor can work. If I give an example to explain the matter, I hope you can understand it very easily. Suppose if a person had many hands, then he could do many things at the same time. That is, if we go to the market and buy a smartphone, then we will see what the configurations of the phone are. If we look closely at the configuration of the smartphone, we will see that Dual Core Processor, Quad Core Processor, Octa core processor, Hexa core processor, Deca core processor. This means that the dual core processor has two arms or cores, ...

How to create a google account from a Android mobile?

 I don't believe a long introduction. I don’t want to bore you.  Today I will teach how to create a google account very flexibly from an android device.  Firstly open a browser like Opera, Firefox, Google Chrome or any other it doesn't matter in that and then type create a Gmail account or  click here After clicking here then click on  create an account  option. Write here your first name and last name exactly. Then write an email address uniquely which did not use in the network or google database. After completing the write a unique email address subsequently you will write a password like  @hga34#@ !. This password format is very effective and efficient against brute force or any other intelligence attack. Now click on the next button  Select your country from here      Enter your mobile number in the orange colour selected blank field. Now enter a recovery email address in the selected field. Anytime if your email address passwo...

What is transmission media? Introduction to different types of data transmission cables

Transmission media: When a PC communicates or wants to communicate with another PC, it has to take the help of some transmission media. The most commonly used media in the network are twisted pair cable, coaxial cable, fiber optic cable. Nowadays, the use of optical fiber is increasing greatly. Radio wave, microwave and infrared technologies are prominent among wireless media. Among these mediums, optical fiber has the highest data transfer speed. The type of medium used in a network depends on the type and location of that network. The connection system for exchanging information between the sender and the remote receiving end is called a channel. The means or methods used to implement the channel are called media. such as-- (i) Cable or wire. (ii) Common telephone lines. (ii) Radio waves. (iv) Microwave. (v) Geo-satellite systems etc. Cable or Wire: Cable is an important medium in data communication. Cables are generally used for data transfer over short range networking such as LAN...
