Module 3 Quiz (Telecommunication)

Fiber optic cable is the correct answer because it is made up of thin, transparent strands of glass or plastic that transmit pulses of light. Many cable and telephone companies use fiber optic cables for their main trunk lines because they can transmit data much faster than wireless channels, about 1000 times faster.

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.

Abner receives the message because Kayla texts him to ask for a favor. He is the intended recipient of the message and is expected to pick her up at the airport. The other options, such as sending the message or being the medium or communication channel, do not accurately describe Abner's role in this scenario.

The correct answer is Satellite link because satellites orbit at 22,000 miles above the earth and can transmit signals over long distances without any problem. The terms "uplinking" and "downlinking" are commonly used when referring to satellite transmissions.

Microwaves are able to transmit data from one place to another because their energy can penetrate various obstacles such as heat, light rain and snow, clouds, and smoke. This characteristic allows microwaves to effectively transmit signals and data without being significantly affected or blocked by these elements.

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.

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.

Telecommunications refers to the transmission and reception of all types of data, including voice, video, and other forms of information, across a distance using a communication channel. It encompasses the use of various technologies and devices such as networks, modems, and UPS (Uninterruptible Power Supply). Therefore, the correct answer is "Telecommunications" as it encompasses all types of data transmissions and receiving across a distance.

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.

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.

Coaxial cable is widely used for cable TV and can connect parts of a LAN for longer distances. It is capable of carrying voice and data at speeds up to about 200 Mbps.

The correct answer is "Real-time" because a videoconference allows for live communication and interaction between Saint Johns College and the other Jesuit Institution. It enables participants to see and hear each other in real-time, simulating a face-to-face meeting despite being in different locations. This type of communication is instant and does not involve any delay or offline interaction.

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.

Twisted Pair Cable is the correct answer because it is the cheapest form of cabling used to connect parts of a LAN over short distances. It does not provide good protection against electrical and noise interference, making it less reliable compared to other options such as Coaxial Cable or Fiber Optic Cable.

For online collaboration to share ideas and find solutions to environmental issues, the essential communication tools would be a computer, communications software, and a modem. A computer is needed to access and use the communication tools. Communications software enables communication and collaboration between individuals or groups over the internet. A modem is necessary to connect the computer to the internet and facilitate online collaboration. Therefore, the combination of a computer, communications software, and a modem would be essential for effective online collaboration in addressing environmental issues in the Caribbean region.

Corporate networks that use the infrastructure standards of the Internet are called Intranets. An Intranet is a private network that is only accessible to authorized users within an organization. It uses the same protocols and technologies as the Internet, such as TCP/IP and HTTP, but is restricted to internal use. An Intranet allows employees to access company resources, share information, and collaborate on projects securely within the organization's network. It provides a secure and controlled environment for communication and data sharing within the company.

All of the options mentioned (telephone, computer, facsimile, and modem) can assist William in getting the information he needs. He can use a telephone to call the university and inquire about the scholarships. A computer can be used to access the university's website or online resources to gather information about the scholarships. A facsimile machine can be used to send or receive documents related to the scholarship application. And a modem can be used to connect to the internet and access online information and resources provided by the university.

Microwaves are the type of signals being used between a cellular telephone and a cellular tower. Microwaves are electromagnetic waves with wavelengths ranging from one meter to one millimeter. They are used in cellular communication due to their ability to carry large amounts of information and their ability to travel long distances without significant loss of signal strength.

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.

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.
