In the case of TCP/IP protocol‚ the Transport Layer provide more complex services such as flow control or connectionoriented data stream transfer to increase the reliability of the data as it is sent through the network. ● By keeping these layers separate‚ the transport layer is able to provide a uniform networking interface where the actual topology of the underlying network can be hidden. This allows services such as flowcontrol‚ error detection/correction and connection protocols such as TCP to exist

Three-Tiered Architecture As all of the components of the client-server architecture need to be connected over a network from server to server‚ performance problems arrive with bottlenecks on the server side of things. This problem could cause a system to be a failure or not be able to adapt well over time. A natural solution to this problem would be to try and remove those bottlenecks by splitting the server side of things into several servers‚ which all do different things with the data. This

network. There are so many ways that information can be shared over the internet either by an organization ’s employee for example just searching on the net or by hackers trying to break into the network. Thus‚ organizations need to implement a security device such as a firewall to protect them from the world (internet). A firewall is a security device that acts as a barrier between two networks‚ i.e. an organization and the internet. There are two types of firewalls‚ either hardware or software.

Most network modems connect via an Ethernet cable but USB connections are becoming increasingly common. The cable plugs into the router jack named "WAN" or "uplink" or "Internet." After connecting the cable‚ be sure to power cycle (turn off and turn back on) the modem to ensure the router recognizes it. 4. Connect one

The computers are current enough to be useful for at least two years. The library‚ which is somewhat centrally located‚ is where the server(s) and router connecting the school to the Internet will be located. Assume that all rooms will have 24 computers and that each room will use a stackable hub solution that combines
