What is the definition of bandwidth?

The amount of data that can be transmitted over a network in a given time period.

What is a bit?

The smallest unit of data in computing, representing a binary value of either 0 or 1.

What is a byte?

A group of 8 bits, representing a single character of text or a small amount of data.

What is the difference between synchronous and asynchronous communication?

Synchronous communication requires both sender and receiver to operate at the same clock speed, while asynchronous communication allows them to operate at different clock speeds.

What is download speed?

The rate at which data is transferred from the internet to your device.

What is upload speed?

The rate at which data is transferred from your device to the internet.

What is latency?

The time it takes for data to travel from one point to another on a network.

Why is low latency important for online gaming?

Low latency is essential for smooth gameplay, as high latency can cause delayed actions and increased difficulty.

What is the function of the ping utility?

To test the reachability of a host on an Internet Protocol network and measure the round-trip time.

What are the two types of IP addresses?

Static (remain the same) and Dynamic (assigned automatically by the ISP).

What is an IPv4 address?

A 32-bit string of digits written as four numbers separated by periods, with a limited pool of around 4.3 billion unique addresses.

What is an IPv6 address?

A 128-bit hexadecimal number written as eight 16-bit fields separated by colons, with a much larger pool of around 340 undecillion unique addresses.

What are some residential applications of broadband?

Home entertainment, remote work, education, and smart home technology.

What is a key benefit of conducting a speed test?

To verify service quality and ensure you're receiving the speeds promised by your ISP.

What is the main concern of latency in video conferencing?

High latency can lead to echoes, delays, and choppy video, making communication difficult.

What is a unique numerical label assigned to each device connected to a computer network?

An IP address.

What is the smallest unit of data in computing?

Bit.

Which type of communication involves both sender and receiver operating at the same clock speed?

Synchronous.

What is the time taken for data to travel from one point to another called?

Latency.

Which of the following is NOT an application of broadband in the residential sector?

Industrial automation.
