47) What is a domain name? What is the procedure to get a domain name?

A domain name is a worldwide-unique name that is affiliated with a public IP address. When an organization or individual wants to register a domain name, it goes to a company that applies to an ICANN (Internet Corporation for Assigned Names and Numbers) approved agency to do so. The company will first determine if the desired name is unique, worldwide. If so, it will apply to register that name to the applicant. Once the registration is completed, the applicant can affiliate a public IP address with the domain name. From that point onward, traffic for the new domain name will be routed to the affiliated IP address.

10) What is the difference between a local area network (LAN) and a wide area network (WAN)? Give an example of how each one could be used in businesses.

A local area network (LAN) connects computers that reside in a single geographic location on the premises of the company that operates the LAN. Wide area networks (WANs) connect computers at different geographic locations. The computers in two separated company sites must be connected using a WAN. With a LAN, the number of connected computers can range from two to several hundred, but they are still in a single location (usually within a building or floor of a building). Most small businesses have a LAN in their office that connects them. A university campus connects all the different buildings on the campus and possibly multiple campuses via a WAN.

48) What are the different tiers in the three-tier architecture used by Web applications?

Almost all web applications use the three-tier architecture, which is an arrangement of user computers and servers into three categories, or tiers. The user tier consists of computers, phones, and other devices that have browsers that request and process Web pages. The server tier consists of computers that run Web servers and process application programs. The database tier consists of computers that run a database management system (DBMS) that processes requests to retrieve and store data.

32) What are the three important functions of an Internet service provider (ISP)?

An ISP has three important functions. First, it provides the client with a legitimate Internet address. Second, it serves as a gateway to the Internet. The ISP receives the communications from a client's computer and passes them on to the Internet, and it receives communications from the Internet and passes them on to the client. Finally, ISPs pay for the Internet. They collect money from their customers and pay access fees and other charges on their behalf.

46) Differentiate between private and public Internet protocol (IP) addresses. Explain the benefits of the private/public IP address scheme.

Public IP addresses identify a particular device on the public Internet. Because public IP addresses must be unique worldwide, their assignment is controlled by a public agency known as Internet Corporation for Assigned Names and Numbers (ICANN). Private IP addresses identify a particular device on a private network, usually on a local area network (LAN). Their assignment is controlled within the LAN, usually by the LAN device. The private/public IP address scheme has two major benefits. First, public IP addresses are conserved. All of the computers on the LAN use only one public IP address. Second, by using private IP addresses, users are protected from attackers directly attacking them because attackers cannot send attack packets to private IP addresses. Attackers can only send packets to devices with public IP addresses. AACSB: Information Technology Difficulty: Moderate Course LO: Compare and contrast different ways of connecting to the Internet.

44) What is the TCP/IP Protocol architecture? Where are the various application-layer protocols?

The protocols used on the Internet are arranged according to a structure known as the TCP/IP Protocol architecture. This architecture has five layers, and one or more protocols are defined at each layer. Data communications and software vendors write computer programs that implement the rules of a particular protocol. For protocols at the bottom layer, the physical layer, they build hardware devices that implement the protocol. The top layer, or the application layer, concerns protocols used between browsers and Web servers. Hypertext Transport Protocol (http), Simple Mail Transfer Protocol (smtp), and File Transfer Protocol (ftp) are application-layer protocols.

49) How does a Web server differ from a commerce server?

Web servers are programs that run on a server-tier computer and manage traffic by sending and receiving Web pages to and from clients. A commerce server is an application program that runs on a server-tier computer. Typical commerce server functions are to obtain product data from a database, manage the items in a shopping cart, and coordinate the checkout process. When a request comes to the server, the Web server examines it and sends it to the proper program for processing. Thus, the Web server passes e-commerce traffic to the commerce server. It passes requests for other applications to those applications. AACSB: Information Technology Difficulty: Moderate Course LO: Describe the components of an information system (IS).
