What is the most common internetwork protocol?
Correct Answer
A. HTTP
Explanation
HTTP (Hypertext Transfer Protocol) is the most common internetwork protocol because it is the foundation of data communication for the World Wide Web. It allows the transfer of hypertext documents, such as web pages, between clients and servers. HTTP is widely used for accessing websites, sending and receiving data, and communicating with web servers. It is a stateless protocol that operates on top of TCP/IP, making it reliable and efficient for transmitting information over the internet. UDP (User Datagram Protocol), TCP (Transmission Control Protocol), and FTP (File Transfer Protocol) are also internetwork protocols but they are not as commonly used as HTTP.
8.
What type of system is UDP?
Correct Answer
B. Best Effort Delivery System
Explanation
UDP stands for User Datagram Protocol, which is a transport layer protocol in computer networking. It is a connectionless and unreliable protocol, meaning it does not guarantee delivery of data packets or ensure their order. Instead, UDP provides a best effort delivery system where it simply sends the data packets without any error checking or acknowledgment. This makes UDP suitable for applications that prioritize speed and efficiency over reliability, such as streaming media, online gaming, and DNS. Therefore, the correct answer is "Best Effort Delivery System".
9.
What is the transport protocol that manages the individual conversations between web servers and web clients?
Correct Answer
A. FTP
Explanation
FTP (File Transfer Protocol) is not the correct answer for this question. FTP is a protocol used for transferring files between a client and a server, but it does not manage individual conversations between web servers and web clients. UDP (User Datagram Protocol) is also not the correct answer as it is a connectionless protocol that does not manage individual conversations. TCP (Transmission Control Protocol) is a reliable transport protocol that manages individual conversations between web servers and web clients, ensuring the delivery and ordering of packets. HTTP (Hypertext Transfer Protocol) is a higher-level protocol that runs over TCP and is responsible for the communication between web servers and web clients.
10.
What factor is crucial to enabling complex interactions?
Correct Answer
E. A & C
Explanation
Standards and protocols are crucial factors for enabling complex interactions. Standards provide a set of guidelines and specifications that ensure compatibility and interoperability between different systems and devices. They establish a common language and framework for communication. Protocols, on the other hand, define the rules and procedures for transmitting data and conducting interactions between systems. Together, standards and protocols enable complex interactions by providing a standardized and reliable way for systems to communicate and exchange information.
11.
What are the two most common transport protocols?
Correct Answer
A. TCP && UDP
Explanation
TCP (Transmission Control Protocol) and UDP (User Datagram Protocol) are the two most common transport protocols used in computer networks. TCP is a reliable and connection-oriented protocol that ensures the delivery of data packets in the correct order and without errors. UDP, on the other hand, is a connectionless and unreliable protocol that does not guarantee the delivery of packets or their order. Both protocols are widely used in various applications and services, with TCP being commonly used for web browsing, email, and file transfer, while UDP is often used for streaming media, online gaming, and real-time communication.
