Question
Which of the following is required to communication between two computers?a.Protocolb.Communication hardwarec.All of above including access to transmission mediumd.Communications software
Solution
The correct answer is c. All of the above including access to transmission medium.
Here's why:
a. Protocol: This is a set of rules that governs the data communications. It represents an agreement between the communicating devices. Without a protocol, two devices may be connected but not communicating.
b. Communication hardware: This is necessary for the physical transmission of signals. It includes devices like routers, switches, hubs, etc.
c. Access to transmission medium: The transmission medium is what carries the signal from one computer to another. This could be a physical medium like a wire, or it could be wireless like radio waves.
d. Communications software: This is necessary for the effective and efficient communication between computers. It includes software for email, web browsing, instant messaging, etc.
So, all of these components are necessary for communication between two computers.
