100-150 Question 7
Select 3A small business is setting up its first network and needs to ensure all devices can communicate with each other. Which fundamental building blocks of a network must be implemented to enable communication between devices?
- A
End devices such as computers and printers
- B
Intermediary devices like switches and routers
- C
Network protocols such as TCP/IP
- D
Firewall rules for enhanced security
- E
Cloud storage for data backup
Show answer and explanation
Correct answers: A, B, C
Explanation
To establish a functioning network, the essential building blocks include end devices (which generate and receive data), intermediary devices (which forward and manage data flow), and network protocols (which define communication standards). These components ensure that devices can connect and exchange information effectively. Security measures like firewalls and additional features like cloud storage are important but not fundamental for basic network communication.
- A. Correct.
End devices, such as computers and printers, are critical components of a network as they send and receive data. Without them, communication cannot occur.
- B. Correct.
Intermediary devices, like switches and routers, are required to connect the end devices and manage traffic between them. They are fundamental for enabling communication in a network.
- C. Correct.
Network protocols, such as TCP/IP, define the rules and standards for communication between devices. They are essential for ensuring devices understand and process data correctly.
- D. Incorrect.
While firewall rules enhance security, they are not a fundamental building block required for basic communication between devices in a network.
- E. Incorrect.
Cloud storage is not a fundamental building block of a network. It is an additional feature for data storage and backup, but it does not directly enable device communication.
