Correct Answer
A. An IP Address is a unique number consisting of 4 parts separated by dots (eg: 217.247.84.89) asociated with every system connected to a network
Explanation
An IP address is a unique numerical identifier that is assigned to every device connected to a network. It consists of four parts separated by dots, such as 217.247.84.89. This address allows devices to communicate with each other over the internet. It is not the address of an internet provider or the location of internet packets, but rather a specific identifier for each device on a network. Therefore, the correct answer is that an IP address is a unique number associated with every system connected to a network.

This type of storage is commonly used in computers to store files, programs, and other data for long-term use.
19.
This is a measurement of speed over a network.
Correct Answer
D. Megabits per second.
Explanation
This question is asking for a measurement of speed over a network. Megabits per second is the correct answer because it is a commonly used unit to measure the speed of data transmission in computer networks. Megabytes, bits, and megahertz are not suitable units for measuring network speed. Megabits per second is a more appropriate unit as it represents the amount of data that can be transmitted in one second.
20.
Bandwidth
Correct Answer
B. A measurement of how much information can be carried in a given time period (usually a second) over a wired or wireless communications link.
Explanation
Bandwidth refers to the measurement of how much information can be carried in a given time period, typically a second, over a wired or wireless communications link. It represents the capacity or speed at which data can be transferred from the server to the client. It is not related to the unit of information or computer storage equal to one billion bytes, which is known as a gigabyte. Therefore, the correct answer is that bandwidth is a measurement of how much information can be carried in a given time period over a communications link.
