A.
1st Generation
B.
2nd Generation
C.
3rd Generation
D.
4th Generation

Explanation :
First Generation computers are characterized by the use of vacuum tubes. These vacuum tubes were used for calculation as well as storage and control.
Explanation :
Composite key is formed when two or more fields of a database table are combined together in order to uniquely identify the records stored in the table.
[16] Which of the following is not a normal form in DBMS?
A.
First Normal Form (1NF)
B.
Second Normal Form (2NF)
C.
Third Normal Form (3NF)
D.
Ninth Normal For (9NF)
Ans:
Ninth Normal For (9NF)
Explanation :
In DBMS, the commonly used normal forms are 1NF, 2NF, 3NF and BCNF.
[17] In PowerPoint, view displays all slides of the presentation as a thumbnail and is helpful for repositioning slides?
A.
Slide Design
B.
Slide Sorter
C.
Slide Show
D.
Slide Master
Ans:
Slide Sorter
Explanation :
The Slide Sorter view is a powerful feature of PowerPoint which displays all of slides of a presentation on a single screen in the form of thumbnails. In this view, you can change the sequence of the slides.
[18] Moving a paragraph in MS-word from one place to another can be done by which of the following actions?
A.
Select, copy
B.
Select all, cut
C.
Select, cut and paste
D.
Select, design
Ans:
Select, cut and paste
Explanation :
You can move a letter, word or paragraph by first selecting it, cutting it and then pasting it to the intended location.
[19] Which of the following are tags, when placed on an animal, can be used to record and track in a database all of the animal's movements?
A.
POS
B.
RFID
C.
OCR
D.
AR
Ans:
RFID
Explanation :
Radio-frequency identification (RFID) uses electromagnetic fields to automatically identify and track tags attached to objects. The tags contain electronically stored information. Passive tags collect energy from a nearby RFID reader's interrogating radio waves.
[20] Which of the following statements is true for baseband signal?
A.
It is the source signal
B.
It frequency is relatively close to zero
C.
It is a modulated signal
D.
Option (1) and (2)
Ans:
Option (1) and (2)
Explanation :
Baseband signals are the information signals that are transmitted without modulation. These signals possess low frequency relatively close to zero.
[21] Which of the following application layer protocols does not use UDP?
A.
FTP
B.
VoIP
C.
DNS
D.
SNMP
Ans:
FTP
Explanation :
Each application layer protocol uses one of the transport layer protocols for transmitting data from one end to another. UDP is an unreliable protocol that does not provide any acknowledgment for the receipt of the data.

A.
Union
B.
Join
C.
Product
D.
Intersect
Ans:
Union
