Assess the significance of protocols and standards in computer systems. Determine one (1) standard and one (1) protocol that you believe to be the most important ones utilized today. Provide a rationale for your response.

A protocol is a set of rules that governs the communications between computers on a network. In order for two computers to talk to each other, they must be speaking the same language. Many different types of network protocols and standards are required to ensure that one computer can communicate with another computer located on the next desk or half-way around the world.

The most important protocol is TCP/IP. The transport layer is concerned with efficient and reliable transportation of the data packets from one network to another. In most cases, a document, e-mail message or other piece of information is not sent as one unit. Instead, it is broken into small data packets, each with header information that identifies its correct sequence and document.

Web pages are constructed according to a standard method called Hypertext Markup Language (HTML). An HTML page is transmitted over the Web in a standard way and format known as Hypertext Transfer Protocol (HTTP). This protocol uses TCP/IP to manage the Web transmission.

Compare and contrast client-server computing and cloud computing. Determine the major risks and rewards that each offers to the organizations that use such approaches. Justify your response.

In Client-Server Computing the data is store by the owner where, in Cloud Computing data is stored by cloud provider.   Also, in client-server computing companies must manage and maintain their own servers; and cloud computing the servers are manage and maintained by the provider.

Client-Server:

Risk: Failure to properly configure firewalls, failure to authenticate network users, use of weak or no wireless encryption, and failure to patch.  

Reward: Corporate data and associated rules are controlled and managed centrally and users can...
