    • To enable software engineers and programmers to accurately determine how an organisation's data is used by particular applications

    • To enable software engineers and programmers to accurately predict the degree to which a demographic will adopt or accept a new product or innovation

    • To enable software engineers and programmers to accurately determine the requirements that a database must fulfill in order to function properly for an organisation

    • To enable software engineers and programmers to accurately map technology solutions to business needs

    Correct Answer
    A. To enable software engineers and programmers to accurately map technology solutions to business needs
    Explanation
    In computer science and Web technology, ontology is the study of how a particular part of a company, called a domain, is organised. The product of an ontological study, called an ontology, describes how individual elements of a domain relate to each other. An ontological study is a foundational step for programmers and designers of complex information technology systems. If properly conducted, an ontology allows software engineers and programmers to accurately map technology solutions to business needs.

    A domain name consists of letters (and sometimes numbers) separated by periods. Which of the following is the host name component of a domain name?  

    • The left-side component of the domain name, which categorizes domains into groups by server name

    • The left-side component of a domain name which categorizes domains into groups by common type or geography

    • The right-side component of a domain name which categorizes domains into groups by common type or geography

    • The right-side component of a domain name which categorizes domains into groups by server name

    Correct Answer
    A. The left-side component of the domain name, which categorizes domains into groups by server name
    Explanation
    A domain name read right to left signifies general divisions, then specific companies then departments within the company and even individual computers (such as a Web server or an e mail server). For example, reading right to left the domain name www.ClWcertified.com can be interpreted as follows .com (domain category - a commercial site), ClWcertified (registered company domain name), and www (the Web server at the company also called the Web site host)

    Which statement accurate describes the difference between a traditional modem and an ISDN line?  

    • A modem connects a user to an all-digital network, whereas ISDN adapts a computer to a phone line or cable TV network.

    • ISDN translates digital signals to analog and back, whereas a modem uses digital line.

    • ISDN uses a digital line, whereas a traditional modem must translate digital signals to analog and back.

    • A model provides a dial-up internet connection, whereas an ISDN line provide a direct Internet connection.

    Correct Answer
    A. ISDN uses a digital line, whereas a traditional modem must translate digital signals to analog and back.
    Explanation
    A modem is a device that enables computers to transmit data over standard analog telephone lines by converting digital data from a computer into an analog signal for transmission over the telephone line to another modem. The receiving modem converts the analog signal back into digital code and transmits it to the receiving computer. To gain faster dial-up connections, individuals who also go through a local phone company to install an Integrated Services Digital Network (ISDN) line, which is a digital telephone line.

    What is a node?

    • A system or application on a network that requests a service from another computer

    • An organised repository of data that can be queried and searched by users

    • A network computer that manages network resources and provides data

    • Any entity or addressable device on a network that can be managed

    Correct Answer
    A. Any entity or addressable device on a network that can be managed
    Explanation
    A node is any entity on a network that can be managed such as a system repeater router gateway or firewall It is a computer or other addressable device attached to a network and also known as a host Many networks are structured using the client/server model in which individual computers and devices called nodes interact with one another through a central server to which they are all connected The client/server model divides processing and storage tasks between the client and the server. A client is a system or application on a network that requests a service from another computer (the server) and is used to access files or documents (such as a Web browser or user agent) A server is a computer in a network that manages the network resources and provides or serves information to clients. A database is an organized repository of data that can be queried and searched by users.

    Which protocol is used to receive e-mail messages from an incoming mail server and force you to download e-mail messages before reading, deleting, or otherwise managing them?  

    • Post Office Protocol (POP)

    • Simple Mail Transfer Protocol (SMTP)

    • Internet Message Access Protocol (IMAP)

    • Network News Transfer Protocol (NNTP)

    Correct Answer
    A. Post Office Protocol (POP)
    Explanation
    You receive mail from an incoming mail server using Post Office Protocol (POP) or Internet Message Access Protocol (|MAP). POP stores incoming e-mail until users authenticate and download it POP is the more accepted and widely used protocol for receiving and managing e-mail. POP servers store and forward e-mail messages to the host. For example if you were to send an e-mail message the message would be stored in the appropriate mail server until the recipient downloaded it from the server. The POP server responds to a request asks for a password then forwards the messages immediately. IMAP handles messages in a more sophisticated manner than POP because it allows you to browse and manage e-mail messages while they reside on the server. A POP server forces you to download e-mail messages before reading deleting or otherwise managing them You send e-mail to others with an outgoing server using Simple Mail Transfer Protocol (SMTP) which is responsible solely for sending - not receiving - e-mail messages. A news server uses the Network News Transfer Protocol (NNTP) to host newsgroups.

    Which protocol is used to send Web pages from a Web server to a Web browser?  

    • Hypertext Transfer Protocol (HTTP)

    • Hypertext Markup Language (HTML)

    • Post Office Protocol (POP3)

    • File Transfer Protocol (FTP)

    Correct Answer
    A. Hypertext Transfer Protocol (HTTP)
    Explanation
    Hypertext Transfer Protocol (HTTP) is the protocol used to transfer Web pages from a Web server to a Web client usually a Web browser. Specifically HTTP is the set of rules required to exchange files such as text images video and multimedia content across the Web. HTML is the language used to create Web pages FTP is used to transport large files of various types POP transports e-mail messages.

    What is the main difference between a Postscript (PS) file and an Encapsulated Postscript (EPS) file?  

    • A PS file contains instructions that determine the display of the graphic whereas an EPS file includes the bitmap information for the image as well

    • PS is the audio format used by UNIX servers whereas EPS is the audio format used by Windows servers

    • A PS file is used to transport text files between operating systems and applications whereas an EPS file is used to transport audio or video content between operating systems and applications.

    • A PS file compresses graphics whereas an EPS file compresses audio or video content.

    Correct Answer
    A. A PS file contains instructions that determine the display of the graphic whereas an EPS file includes the bitmap information for the image as well
    Explanation
    Postscript (PS) files are written in a page description language so they are unreadable and are designed for printing on Postscript printers. Encapsulated Postscript (EPS) is a file format that you can use to import and export graphics files between operating systems and applications. Whereas a Postscript file only has the instructions that determine the display of the graphic an EPS file actually contains the bitmap information for the graphics file.
