Week13

  1. 1. Using an Internet Within a Company Intranet Firewall Subcontractors CGI
  2. 2. Intranet Intranet is a private computer network that uses Internet technologies to securely share any part of an organization's information or operational systems with its employees. Sometimes the term refers only to the organization's internal website, but often it is a more extensive part of the organization's computer infrastructure and private websites are an important component and focal point of internal communication and collaboration.
  3. 3. Firewall A firewall is a part of a computer system or network that is designed to block unauthorized access while permitting authorized communications. It is a device or set of devices configured to permit, deny, encrypt, decrypt, or proxy all (in and out) computer traffic between different security domains based upon a set of rules and other criteria.
  4. 4. Subcontractor A subcontractor is an individual or in many cases a business that signs a contract to perform part or all of the obligations of another's contract. A subcontractor is hired by a general contractor to perform a specific task as part of the overall project. Whilst the most common concept of a subcontractor is in building works and civil engineering, the range of opportunities for subcontractor is much wider and it is possible that the greatest number now operate in the information technology and information sectors of business.
  5. 5. CGI CGI is a standard protocol for interfacing external application software with an information server, commonly a web server. The task of such an information server is to respond to requests by returning output. Each time a request is received, the server analyzes what the request asks for, and returns the appropriate output.
