Networks Quiz

Imagine you're setting up a high-speed internet connection for a remote office located in a mountainous area. Which technology would you likely use?

• Electronic communication without the need for cables.

• Network connection point for devices. Data arriving at a hub is copied and sent to all the devices on the network.

• Electronic equipment that converts computer digital signals into audio signals and back. The audio signals are transmitted over telephone lines, allowing for distant communication.

• Computer network where all the connected computers are within a limited geographical area (e.g., a home, school, etc.). Connection between the computers may be through cables and/or microwave transmission.

You're sending a digital postcard to a friend. Before it reaches them, how does the system ensure that the postcard hasn't been tampered with during transmission?

• By using a checksum, an error-detecting procedure that generates a sum from the digits of a number, to verify the integrity of the data.

• By including a portion of the message that is transmitted through the network, containing data such as check digits and destination address.

• By employing a link that resides between computer networks and is responsible for converting data passing through into the appropriate format so it can be understood by the receiving network.

• By initiating an exchange of predetermined signals to signify that a connection has been established between two systems.

Sean is setting up a new local area network (LAN) in an office. What process describes the initial exchange of signals between your computer and the router to establish a connection?

• Exchange of predetermined signals to signify that a connection has been established between two systems.

• Network connection point for devices. Data arriving at a hub is copied and sent to all the devices on the network.

• International communications standards allow for the transmission of audio/video and other data over digital telephone lines.

• Electronic communication without the need for cables.

Amy wants a small office network setup where all computers need to share a single internet connection. Which topology would be most suitable for this scenario?

• A network design where a single cable runs through the entire office connecting all devices, allowing them to share the internet connection.

• Various types of cables such as copper (coaxial and twisted pair) and fiber used for different networking needs.

• An additional digit added to numerical data to ensure its integrity after being input, transmitted, stored, or processed.

• The measure of data's accuracy after it has been input, transmitted, stored, or processed.

What is networking?

• Making use of a network.

• A network connection point for devices. Data arriving at a hub is copied and sent to all the devices on the network.

• A computer network where all the connected computers are within a limited geographical area (e.g., a home, school, etc.). The connection between the computers may be through cables and/or microwave transmission.

• Electronic communication without the need for cables.

Xander is sending a large video file to a friend over the internet. Which method best describes how the internet transmits this video file?

• Breaking the video file into small units of data, called packets, and sending these packets through the network independently.

• Connecting directly to your friend's device through a central network hub, which then copies and sends the entire video file at once.

• Using a local network confined to your immediate physical location to directly transfer the file without going through the internet.

• Transferring the video file wirelessly without using any form of internet connection.

Selena in buying a book online and enters the ISBN number. What role does the last digit of the ISBN number play?

• Extra digit added to numerical data that is used to check data integrity after input, transmission, storage, and processing.

• The accuracy of data after input, transmission, storage, or processing.

• Error-detecting procedure that generates a sum from the digits of a number.

• Portion of a message that is transmitted through a network. Contains data such as check digits and destination address.

Ken is setting up a high-quality video conference system for an international company that requires the transmission of audio, video, and other data over digital telephone lines. Which technology would best suit this requirement?

• ISDN (Integrated Services Digital Network), an international communications standard designed for such purposes.

• Wireless communication technology, which allows for electronic communication without the need for cables.

• A network hub, which is a connection point for devices where data arriving is copied and sent to all devices on the network.

• A Local Area Network (LAN), a computer network where all connected computers are within a limited geographical area, using cables and/or microwave transmission for connection.

Malik is sending a message to a friend over the internet. What is this message technically referred to as?

• Group of bits. May include control signals, error control bits, coded information, as well as the destination for the data.

• Network connection point for devices. Data arriving at a hub is copied and sent to all the devices on the network.

• Computer network where all the connected computers are within a limited geographical area. Connection may be through cables and/or microwave transmission.

• Electronic communication without the need for cables.

Imagine you're setting up a small office network. You need a device that can connect multiple computers together and ensure that data sent from one computer is received by all others in the network. Which device would you use?

• A hub: A network connection point for devices. Data arriving at a hub is copied and sent to all the devices on the network.

• ISDN: International communications standard that allows for the transmission of audio/video and other data over digital telephone lines.

• Wireless communication: Electronic communication without the need for cables.

• Modem: Electronic equipment that converts computer digital signals into audio signals and back. The audio signals are transmitted over telephone lines, which allows for distant communication.
