Pls tell me Exactly what is a Server ?????

Answer 1

A server is a computer that handles requests for data, email, file transfers, and other network services from other computers (ie, clients).

1) In general, a server is a computer program that provides services to other computer programs in the same or other computers. 2) The computer that a server program runs in is also frequently referred to as a server (though it may contain a number of server and client programs). 3) In the client/server programming model, a server is a program that awaits and fulfils requests from client programs in the same or other computers.

Answer 2

Just To make it simpler,

In a Huge Business, THE Big Man or the Boss is the Main server.

He Connects to all his Employees.W/o the Boss, the employees could not do a single thing because they dont have nothing to connect to.


Just like in computers, the servers run the Net.
hostin What ever website they are connected to.
take yahoo for example. All Yahoo user websites are connected to a server.

Answer 3

A server is a computer which is online 24 7 365.
So a server can be your computer, and the people can host a web address on it. more about server if ya want to know i will send you a book. ;)

Answer 4

In information technology, a server (also called a server application) is "an application program that accepts connections in order to service requests by sending back responses." (RFC 2616 (Hypertext Transfer Protocol -- HTTP/1.1)) A server application can run on the same computer as the client application using it, or they can connect through a computer network. Examples include file server, database server, backup server, print server, mail server, web server, FTP server, application server, VPN server, DHCP server, DNS server, WINS server, logon server, security server, domain controller, backup domain controller, proxy server, firewall, etc.

Client Server and Peer to peer: The main differences

There are numerous differences between Client server networks and peer to peer networks and these are factors that a business must think about when considering network design. Profit needs to be made so the appropriate and effective administration of a computer network is imperative.
Client servers use a computer that is the main machine and provides services and information to other nodes on a network. These servers have fixed IP addresses. Client server networks are one way communication .Clients can get, request data from server but server does not need anything back from client. Peer-to-peer means that two communicating computers are on the same level, they are both running the same software, and they communicate as equals. Here are some of the important factors when choosing either client server or peer to peer:
The information stored across peer-to-peer networks is uniquely decentralized unlike client-server networks, where network information is stored on a central file server and made available to many other networked nodes. Because peer-to-peer PCs have their own hard disk drives that are accessible by all computers, each PC acts as both a client (information requestor) and a server (information provider). There are some advantages a peer to peer network has over a client server model; there is no need for a network administrator, this way a form can save labour for other recourses. Also the network is easy to set up and maintain

Cost
A client server network requires a server and this is usually a more powerful machine with a faster CPU and more memory, this will cost more than the other nodes. A peer to peer network is cheaper because you have no server; each node acts as both client and server .The downside of a client server architecture is higher initial funds to establish, and a greater level of technology expertise required to configure and manage, as compared to the peer-to-peer network

Hardware Requirements
A peer to peer network uses less hardware than client server and so is relatively cheaper to implement. For example a bus topology does not require a hub, just a terminator at each end of the line. A powerful server is not needed in peer to peer.
In client-server networks, network printing is normally handled in one of two ways, either by attaching a printer directly to the server or by attaching a print server to the network. When a client-server network needs a gateway to the world, the network administrator in some cases installs a remote node server, which serves a dual purpose, providing remote access as well as modem sharing. Most remote-node servers attach directly to the network cabling and provide a bridge between the network, a modem, and a telephone line.

Security
There is basically no security when it comes to p2p network. Peer to peer offers very little security especially if used with sensitive data where there is practically no security in peer to peer whereas server based can have protected files and authenticated log-ins which provides optimal security. Some users have certain rights that others don't have. Client server networks are configurable for maximum security.
There are many file sharing sites that are available over the internet, sharing files on your computer with anonymous and unknown users goes against many of the basic principles of securing your computer. It is recommended that you have a firewall built into your router or have some personal firewall software. This is where a server is extremely important because it can handle file security more efficiently.
The cost and inconvenience associated with security must be balanced against the cost and inconvenience of corrupted or insecure data.

Administration
There is no need for administration in peer to peer however a server based systems administration can be more challenging. A server requires active directory management to assign users and domains and privileges. A peer to peer network can have more admin rights than a client server model

Max number of users
The maximum number of users much depends on the physical topology. There is a certain distance that the Ethernet cabling can transmit to. A repeater can be used.

A server is nothing more than a huge computer that "holds" various information which computers connect to to retrieve information. Example: When you access your Yahoo email account, all of your information is "held" by a yahoo mail server waiting for you to access it via your computer to retrieve your email. Examples of a server are: File servers, database servers (companies use database for things such as employee files or customer accounts), backup servers (used as a safety in case the main server experiences any problems), print servers, mail servers (used to hold emails for retrieval.)

A server computer is a computer system that has been designated for running specific server software applications. Much like personal computers that are designed to run using Microsoft's Windows Operating system software. Most personal computers (PC's) run using Microsofts Windows operating program and Apple's PC's commonly known as MAC's (short for Macintosh and taken from the macintosh apple), use a specific software designed for MAC's known as MAC OS.

Answer 7

a server is something that can host data such as files like html or php or asp etc or it can be used for many other various reasons, irc (chat) smtp (mail) http(web) and many other uses. most home based servers use software to host a connection. This is then connected to the wan(internet) where many people can vveiw it :)

Answer 8

Server is also a computer with super processing capability of handling huge amount of data with high speed. it will act as an service provider for all the client computers connected to it. it will only have the responsibility to control the overall process of all the activities done on its client computer

Answer 9

- A computer that delivers information and software to other computers linked by a network.
- A process that runs on a host that relays information to a client upon the client sending it a request. Servers come in many forms: application servers, web servers, database servers, and so forth. All IP-based servers can be load balanced. See Web Server.
- A host computer on a network that holds information (eg, Web sites) and reponds to requests for information from it (eg, links to another Web page). The term server is also used to refer to the software that makes the act of serving information possible. Commerce servers, for example, use software to run the main functions of an e-commerce Web site, such as product display, online ordering, and inventory management. You'll also hear this described as "shopping cart technology.
- A server is a computer that handles requests for data, email, file transfers, and other network services from other computers (ie, clients).
- Any computer on a network that contains data or applications shared by users of the network on their client PCs.
- A file server and/or a computer that processes requests for HTML and other documents that are components of web pages.
- In general, a server is a computer program that provides services to other computer programs in the same or other computers.
- The computer that a server program runs in is also frequently referred to as a server (though it may contain a number of server and client programs).
- In the client/server programming model, a server is a program that awaits and fulfils requests from client programs in the same or other computers.
- describes any application that serves another - for example the computers that hold web pages are called servers since they serve up web resources to client applications such as web browsers.
- Can refer to the machine that stores files of many users and programs that can be shared, or to the program that allows communication with a browser. Shared authorship
- A computer that hosts information available to anyone accessing the Internet.
- A high-power computer that is used to store and distribute data and/or applications.
- A machine one can connect to and get news (or mail) from.
- A computer "hard drive" that shares its resources with other computers on the network.
- waiter: a person whose occupation is to serve at table (as in a restaurant)
- (court games) the player who serves to start a point
- (computer science) a computer that provides client stations with access to files and printers as shared resources to a computer network
- utensil used in serving food or drink
- In computing, a server is: computer software application that carries out some task (i.e. provides a service) on behalf of yet another piece of software called a client. In the case of the Web: An example of a server is the Apache Web Server, and an example of a client is the Mozilla Web Browser. Other server (and client) software exists for other services such as e-mail, printing, remote login, and even displaying graphical output...

Answer 10

Greetings,
A server is a computer from which other computers connect or work from.

You internet connection goes through a server.

It is like a gateway, that all need to pass through. To be able to download you need a computer/server to download from.

I do hope that answers your question.

Regards
Aidan
