    What type of signals are being used between a radio and a radio tower.

    • Infrared

    • Radio waves

    • Microwaves

    • Electrical pulses

    • All of the above

    Correct Answer
    A. Radio waves
    Explanation
    Radio waves are the type of signals used between a radio and a radio tower. Infrared signals are not typically used for long-range communication, and microwaves are generally used for shorter-range communication such as in microwave ovens. Electrical pulses may be used for digital communication, but radio waves are the most common and effective type of signals used in radio communication. Therefore, the correct answer is radio waves.

    In an automated information Processing system, a scanner is used for

    • Processing

    • Data capture

    • Presentation

    • Distribution

    • All of the above

    Correct Answer
    A. Data capture
    Explanation
    In an automated information processing system, a scanner is used for data capture. A scanner is a device that converts physical documents or images into digital format, allowing the system to capture and store the data electronically. It does not process the data, present it, or distribute it. Therefore, the correct answer is data capture.

    Rate this question:

  • 7. 

    Which of the following does NOT require a computer for transmission.

    • E-mail

    • Fax

    • Interactive telecommunication

    • Webinar

    • Video-conferencing

    Correct Answer
    A. Fax
    Explanation
    Fax does not require a computer for transmission. Unlike other options such as e-mail, interactive telecommunication, webinar, and video-conferencing, fax machines can send and receive documents without the need for a computer or internet connection. Fax machines use telephone lines to transmit printed materials, making them a standalone communication tool that does not rely on computer technology.

    Data communication is the transfer of data from point A to point B using a communication link. When data travel a long distance, the communication is referred to as telecommunications; The prefix "tele" comes from an ancient Greek word that means a "far off". Which of the following would be classified as telecommunication.

    • Teleconferencing

    • Teleporting

    • Text messaging

    • Video Conferencing

    • All of the above

    Correct Answer
    A. All of the above
    Explanation
    All of the options listed (teleconferencing, teleporting, text messaging, and video conferencing) can be classified as forms of telecommunication. Teleconferencing involves the use of audio and video technology to connect multiple participants in different locations for a meeting or discussion. Teleporting refers to the instantaneous transfer of a person or object from one location to another using advanced technology, which also involves data transmission. Text messaging involves the sending and receiving of written messages between individuals using a communication network. Video conferencing allows individuals in different locations to have a face-to-face conversation using video and audio technology. Therefore, all of these options involve the transfer of data over a communication link, making them forms of telecommunication.

    What type of signals were you using on the last occasion when you used a hand-held remote control to change the channel on your television?

    • Electrical pulses

    • Microwaves

    • Infrared

    • Radio waves

    • All of the above

    Correct Answer
    A. Infrared
    Explanation
    Infrared signals are commonly used in hand-held remote controls to change the channel on a television. These signals are transmitted in the form of infrared light waves, which are not visible to the human eye. When the remote control sends an infrared signal, it is picked up by a sensor on the television, which then processes the signal and changes the channel accordingly. This type of signal is preferred for remote controls because it is reliable, low-cost, and does not interfere with other electronic devices in the vicinity.

    E-mail may be used in an organization for both internal and external communication. Which of the following functions should the e-mail service provide? i. Reply to e-mail messages received ii. Create new messages iii. Receive attachments iv. Send attachments

    • I and ii only

    • Iii and iv only

    • Iii and ii only

    • Ii , iii , and iv only

    • A and B only

    Correct Answer
    A. A and B only
    Explanation
    The e-mail service should provide the functions of replying to e-mail messages received and creating new messages. This is because these two functions are essential for both internal and external communication within an organization. The ability to reply to messages allows for effective communication and collaboration, while the ability to create new messages enables the initiation of new conversations or discussions. The other functions mentioned, receiving and sending attachments, are not explicitly mentioned as necessary for organizational communication and may vary depending on the specific needs of the organization.

    I am susceptible to interference, eavesdropping, and jamming. I provide wireless transmission for mobile communications such as cellular telephones, and for stationary communications where it is impossible to run cable. Who am I?

    • Radio wave link

    • Microwave link

    • Satellite link

    • Coaxail cable

    • Fibre Optic cable

    Correct Answer
    A. Radio wave link
    Explanation
    A radio wave link is susceptible to interference, eavesdropping, and jamming because it uses wireless transmission for mobile and stationary communications. Unlike cables such as coaxial or fiber optic, which are more secure and less prone to interference, radio wave links can be easily disrupted by external factors. Therefore, the correct answer is a radio wave link.

    • Satellite link

    • Microwave link

    • Radio wave link

    • Fibre Optic cable

    Correct Answer
    A. Microwave link
    Explanation
    A microwave link is the correct answer because it transmits data and voice through the atmosphere as high-frequency waves (3-10GHz). These signals are referred to as "line-of-sight" because they cannot travel beyond 30 miles. Microwave link stations are typically located on buildings, towers, and hilltops.
