Bit rate, bandwidth, & latency

Multiple Choice

A computer network is a system of:

• two or more computing devices connected to one another

• Data transfer and information storage

• Sharing devices like scanners

• A whole lot of individual machines working on their own

Multiple Choice

The single unit of information in a computer, typically represented as a 0 or 1.

• bit

• binary

• latency

• bandwidth

Multiple Choice

_________ is a way of representing information using only 2 options.

• Bit

• Binary

• Bit rate

• Bandwidth

Multiple Choice

How many more numbers can be represented with 5 bits as opposed to 4?

• 5 times as many

• 10 times as many

• Twice as many

• 4 times as many

Multiple Choice

Megabits per second (Mbps) refers to a speed of ....

• a million bits per second

• a hundred bits per second

• a thousand bits per second

• a thousand million bits per second

Multiple Choice

How many bits are represented by 1 gigabit unit?

• 1 thousand

• 1 million

• 1 billion

• 1 trillion

• 1 quadrillion

megabit vs. megabyte

• 1 megabyte = 8 megabits.

• Megabits per second (mbps) are generally used to describe the speed of an Internet connection, whereas megabytes (MB) usually refer to the size of a file or storage space.

  
  

• One megabit per second is slow but usable broadband Internet. Five to ten web pages, one minute of music, or a half a minute of video is about one megabyte of data.

• 560,000 bits per second

Multiple Choice

The "bit rate" measures ....

• the server speed

• the cable speed

• the network speed

Multiple Choice
