1)A network is when two or more computers are connected together and are able to share data and communication.

A LAN is a ‘Local Area Network’. It is a small network of computers most often

v) Video/audio stream: Servers can store whole videos on disk and convey them at playback

Client requests file from the cold cache of the server and stores file on its disk.

A protocol is predefined set of rules or conventions which governs the way in which two entities co-ordinately cooperate to exchange data, in any network.

Server: This is a computer that is designed to carry out specific functions at the request of other computers they’re connected to a network and direct the information stored on the network to clients, for example a web server will run software that receives requests from clients and then processes the request and delivers an output using HTML.

Protocols - a protocol is the special set of rules that end points in a telecommunication connection use when they communicate, protocols also specify interactions between the communicating entities. (Tech target, 2004)

A communications protocol characterizes the guidelines for sending pieces of information starting with one hub in a system then onto the next hub. Conventions are regularly characterized in a layered way and give all or part of the administrations indicated by a layer of the OSI reference show. A convention characterizes the operation of the convention and may likewise propose how the convention ought to be actualized. It comprises of three sections:

Master table which contains all the data of the whereabouts of the table. The issue with this approach is that as there is only one master server it can be overloaded with the requests.

A computer and a server are usually two unique and separate devices and each are customized to handle specific functions and purposes. For example a web server will not need any type of display or monitor and can be located anywhere. But when it comes to a data server or client, there is typically a need for some form of display monitor so information can be reviewed and tracked. It is not uncommon in some occurrences that a device can function both as a computer and a server for the same application. This also can hold true for a application act as a client to other server for various other

Server: The server acts as the main computer. It had high end hardware just like the workstations, but

Client Server is a computer system where a central server provides data of networked workstations.

A client/server architecture is an end-to-end systems that contains server hosts (contains the resources and services needed by the client) and clients (users or workstations in the network). “Most client/server networks have more than one client to a server so that the system shares computing power. There are a few different kinds of servers to include file sharing, printer services, email services, database services, web services, and a server can used for it power. Clients can access all of these different servers at one time and the servers can serve many clients.” (Techopedia, 2014) For large businesses with office throughout the country web based computing or cloud computing shows the greatest benefit. In web-based computing it is not the local computer doing all the work but rather computers off site that do the work. The user’s computer runs off of a cloud computing system’s interface software which uses the offsite network computers to do the work.

A computer network is a network that consist of two or more computers that are able to share information between them or their users. There are a large variety of different networks and the advantages or disadvantages are strongly related to the type of network we choose.

Well-known communications protocols are Ethernet, a hardware and Link standard that is ubiquitous in local area networks, and the Internet Protocol Suite, which defines a set of protocols for internetworking, i.e. for data communication between multiple networks, as well as host-to-host data transfer, and application-specific data transmission formats.
