Chapter 1, Problem 1RQ
Program Description Answer
In client server model, the primary protocol used for communication between a browser and web server is HTTP.
Hence, the correct answer is option “C”.
Expert Solution & Answer
Explanation of Solution
HTTP:
- • The web application uses Hyper Text Transfer Protocol (HTTP) as application layer protocol.
- • HTTP is an application protocol for distributive, collaborative, and hypermedia
information systems. - • HTTP is one of the high-level protocols of the World Wide Web used for transmitting documents.
- • It is an application-level protocol used for communication between the client and server in various formats such as text, images, and videos.
Explanation for incorrect options:
FTP:
- • The File Transfer web application uses the File Transfer Protocol (FTP) as application layer protocol.
- • The FTP is a standard application layer tool in a
computer network which is used to transfer files between client and server.
Hence, the option “A” is wrong.
TCP:
TCP stands for Transmission Control Protocol which is a standard that establishes and maintain a network conversion with the use of application programs.
Hence, the option “B” is wrong.
SSL:
SSL stands for Secure Socket Layer and is a security protocol that establishes link between the web browser and the web server in an online communication.
Hence, the option “D” is wrong.
