100-150 Question 10
Select 3A small business is setting up a new network and wants to understand the fundamental building blocks required for proper connectivity and communication. Which of the following are essential conceptual components of a network?
- A
Devices such as routers, switches, and end devices
- B
Protocols like TCP/IP for communication
- C
A cloud-based antivirus solution
- D
Media such as cables or wireless signals for data transmission
- E
Power backup systems for network devices
Show answer and explanation
Correct answers: A, B, D
Explanation
The fundamental building blocks of a network include devices (e.g., routers, switches, and end devices), protocols (e.g., TCP/IP), and media (e.g., cables or wireless signals). These components are vital for enabling connectivity and communication. Other elements, such as security solutions and power backups, enhance the network but are not considered foundational.
- A. Correct.
Devices such as routers, switches, and end devices are fundamental to a network because they enable connectivity, data forwarding, and interaction between users and systems.
- B. Correct.
Protocols like TCP/IP are essential for defining how data is formatted, addressed, transmitted, and received across the network. Without protocols, communication between devices would not be possible.
- C. Incorrect.
A cloud-based antivirus solution is a security feature, not a fundamental building block of a network. It is used to protect data and systems but is not required for basic network functionality.
- D. Correct.
Media, such as cables (Ethernet) or wireless signals (Wi-Fi), is necessary for transmitting data between devices. Without a medium, data cannot travel across the network.
- E. Incorrect.
Power backup systems are useful for ensuring continuity during outages but are not necessary for the basic functioning of a network. They are a complementary feature rather than a building block.
