MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -Typically, bandwidth is represented in the number of bits, kilobits, megabits or gigabits that can be transmitted in 1 second. Synonymous with capacity, bandwidth describes data transfer rate. Bandwidth is not a measure of network speed–a common misconception.

Detailed explanation-2: -Bandwidth indicates how much time is required to transmit or receive information over the given communication network; it tells us the number of bits per second that can be transmitted or received. Consider a communication network of bandwidth 100 Mbps.

Detailed explanation-3: -As to why we measure internet speed in bits even though the internet delivers bytes of data, it is because the internet delivers those bytes of data as single bits at a time.

Detailed explanation-4: -The maximum amount of data transmitted over an internet connection in a given amount of time. Bandwidth is often mistaken for internet speed when it’s actually the volume of information that can be sent over a connection in a measured amount of time – calculated in megabits per second (Mbps).

Detailed explanation-5: -The number of bits per second is known as the bit rate. The number of signal units per second is known as the baud rate. Bit rate determines the number of bits travelled per second.
