  1. CLIENT A client is an application or system that accesses a service made available by a server. 

  2. SERVER The term server is also often generalized to describe a host that is deployed to execute one or more such programs. A server computer is a computer, or series of computers, that link other computers or electronic devices together.  A physical computer dedicated to running one or more such services, to serve the needs of programs running on other computers on the same network.

  3. TYPES OF SERVERS

  4. Server Platforms Server platform is the fundamental hardware or software for a system which acts as an engine that drives the server. It is often used synonymously with an operating system.

  5. Database Server Adatabase server is a computer program that provides database services to other computer programs or computers, as defined by the client–server model.

  6. Application Server Also known as a type of middleware, it occupies a substantial amount of computing region between database servers and the end user, and is commonly used to connect the two.

  7. Audio/Video Server It provides multimedia capabilities to websites by helping the user to broadcast streaming multimedia content. Audio/Video Servers make possible multimedia applications which have ability to broadcast streaming multimedia contents on websites. Multimedia streaming is a technique for transporting data. When client side receives data and forwards it as steady stream it processing the data and covert it into sound and pictures so a user receive data immediately in desired format.

  8. Chat Server  It serves the users to exchange data in an environment similar to Internet newsgroup which provides real time discussion capabilities. ThroughChat Servers a lots of user make conversation and exchange information or data with each other in similar environment and it is possible with real-time discussion capabilities because real time means happening instantly. The real-time offering many features such as navigation, display of moving objects at the same time as text. Real time takes only a minute, or few second to react.

  9. Fax Server It is one of the best option for organizations seeking for minimum incoming and outgoing telephone resources, but require to fax actual documents. AFax Server is commonly used in large organization where time is money. Fax Servers save the time and decrease incoming and outgoing telephone resources

  10. FTP Server It works on one of the oldest of the Internet services, the file transfer protocol. It provides a secure file transfer between computers while ensuring file security and transfer control. File transfer protocol is an oldest internet service which facilitates the user to move one or more than one files from one location to another location securely.  FTP Servers also offering file safety, transfer control and organization of files.

  11. Groupware Server It is a software designed that enables the users to work together, irrespective of the location, through the Internet or a corporate intranet and to function together in a virtual atmosphere.

  12. IRC Server It is an ideal option for those looking for real-time discussion capabilities. Internet Relay Chat comprises different network servers that enable the users to connect to each other through an IRC network.

  13. List Server It provides a better way of managing mailing lists. The server can be either open interactive discussion for the people or a one-way list that provide announcements, newsletters or advertising.

  14. Mail Server It transfers and stores mails over corporate networks through LANs, WANs and across the Internet.

  15. News Server It serves as a distribution and delivery source for many public news groups, approachable over the news network.

  16. Proxy Server It acts as a mediator between a client program and an external server to filter requests, improve performance and share connections.

  17. TelNet Server It enables the users to log on a computer and execute tasks as if they are working on a remote computer.

  18. Web Server It provides static content to a web browser by loading a file from a disk and transferring it across the network to the user's web browser. This exchange is intermediated by the browser and the server, communicating using HTTP.

  19. Assignment • How Does Information Travel from One Computer to Another? • What is a Computer Protocol? • Find the following terms: • Intranet • Extranet • Internet • Ethernet • Virus • Anti-virus • Firewall • Protocol • ISO • IEEE

  20. Intranet Extranet Internet Ethernet Protocol ISO IEEE

  21. Types of Hardware Used in a NetworkIf you want to know the basics of computer networking, you will also have to gain some information about the various hardware that is used to maintain connections between the network.Network Interface Cards (NIC)A network interface card, also known as a network adapter, is a very important component installed in a computer which is responsible for connecting a particular computer to a network.SwitchesA switch is an equipment responsible for undertaking the forwarding and filtering of data based on the Media Access Control (MAC) address of the network cards involved in communication.HubsThis device is similar to a switch, however, it is incapable of filtrating the data packets based on their MAC address, and instead, sends all packets to all devices. It generally has a better performance value on a computer network.RoutersA router is the primary device responsible for connecting multiple networks together. It connects the computer to the Internet, and functions at the third layer of the OSI model.

  22. How Does Information Travel from One Computer to Another?Every Local Area Network uses a technology called the Ethernet. Using this technology, the data is broken into small pieces called packets of data. Every packet of data, has a head and in some cases a tail. The head contains various information, like the destination address, the checking bits etc. The other computer on receiving that packet sends in an acknowledgment packet, to notify that it has successfully received that piece of data and is now in a position to receive new data. This is the basic principle of working of data. To understand even more clearly, how data travels, we need to understand the term protocols.What is a Computer Protocol?A computer networking protocol is nothing but a set of rules that defines the way data and information will be transferred from one computer to another. These set of rules will define, when to send a packet of data, when an acknowledgment signal should be given, etc. The most common protocol, that we must have heard and which is used over in the largest network i.e., the Internet is TCP/IP model. This protocol is divided into two parts, TCP (Transmission Control Protocol) which decides how the systems will communicate with each other and IP (Internet Protocol), which handles the part for addressing the packets and routing them to their respective destinations. This is all that I can provide on information about computer networking within the scope that I have. There is more that can be written for computer networking information and volumes can be written about each and every term that has been discussed above. A detailed information on computer networking is of utmost importance, before you plan to set up any computer network.
