100-150 Question 8
Select 4You are troubleshooting a small office network and need to explain the fundamental conceptual building blocks of networks to a colleague. Which of the following are considered essential components of a network?
- A
End devices such as computers and printers
- B
Switches and routers for data forwarding
- C
Applications such as email and web browsers
- D
Media such as cables or wireless signals
- E
Protocols such as TCP/IP for communication
Show answer and explanation
Correct answers: A, B, D, E
Explanation
The fundamental conceptual building blocks of a network include end devices (to send and receive data), networking devices like switches and routers (to forward and manage traffic), media (to physically or wirelessly connect devices), and protocols (to define communication rules). Applications, while important, are not fundamental parts of the network itself as they operate at higher levels and rely on the underlying network infrastructure.
- A. Correct.
End devices like computers, printers, and phones are crucial components of a network because they generate or receive network traffic.
- B. Correct.
Switches and routers are essential for forwarding data packets within and between networks, making them critical building blocks.
- C. Incorrect.
Applications like email and web browsers are not fundamental building blocks of a network; they operate on top of the network and rely on its infrastructure to function.
- D. Correct.
Media, such as Ethernet cables or wireless signals, provide the physical or wireless pathways for data transfer, making them essential network components.
- E. Correct.
Protocols like TCP/IP define the rules for communication between devices, ensuring interoperability and data transfer, which makes them a core part of networks.
