(a) TML

(b) COBOL

(d) C++

(e) TCP/IP

S4. Ans.(e)

Sol.

TCP/IP, which stands for Transmission Control Protocol/Internet Protocol, is an industry-standard protocol suite for WANs. On the other hand, HTML, COBOL, JAVA and C++ are computer programming languages.

Q5. The feature in database language that allows us to access certain records in database is called __________.

(a) Query

(b) Forms

(d) Tables

(e) Node

S5. Ans. (a)
Sol.

Query allows us to access certain records in database.

Q6. UDP and TCP are categorized under the ___layer of the OSI model.

(a) Data link

(b) Application

(d) Transport

(e) Session

S6. Ans.(d)

Sol.

The transport layer is a conceptual division of methods in the layered architecture of protocols in the network stack in the Internet Protocol Suite and the Open Systems Interconnection (OSI). The protocols of the layer provide host-to-host communication services for applications

Q7. SMTP, FTP and DNS are applications/protocols of the _____ layer.

(a) Data link

(b) Network

(d) Application

(e) None of these

S7. Ans.(d)
