1. Sending a frame to a group of stations is known as __________. [S.S.C. Online Graduation Level (T-I) 7.09.2016 (Shift-2)]

(a) Single casting
(b) Spreading
(c) Multicasting
(d) Casting

Correct Answer: (c) Multicasting

Solution:

In addition to transmitting frames directed to a single address, local area networks are capable of sending frames directed to a group of address, called a multicast address, which can be received by a group of stations. They can also send frames directed to all stations using the broadcast address. A frame sent to multicast destination address can be received by all stations configured to listen for that multicast address.

2. DNS is a networking term which refers to_________. [S.S.C. Online CHSL (T-1) 10.01.2017 (Shift-III)]

(a) Domain Name System
(b) Digital Network Service
(c) Disc numbering sequence
(d) Data Numbering System

Correct Answer: (a) Domain Name System

Solution:The domain name system (i.e., "DNS") is responsible for translating domain names into a specific IP address so that the initiating client can load the requested Internet resources. The domain name system works much like a phone book where users can search for a requested person and retrieve their phone number.

(a) APPEND
(b) RENAME
(c) RESTORE
(d) ADD

Correct Answer: (a) APPEND

Solution:The command that merges the contents of one file with another is called APPEND.
RENAME command is used to change the name of the file.
RESTORE command is used to restore the contents of the file.

4. Which of the following is the operation executed on data stored in registers? [S.S.C. Online Graduation Level (T-1) 8.09.2016 (Shift-2)]

(a) Bit-operation
(b) Macro-operation
(c) Micro-operation
(d) Byte-operation

Correct Answer: (c) Micro-operation

Solution:The operations executed on data stored in registers are called Micro operations. Micro operation is an elementary operation performed (during one clock pulse), on the information stored in one or more registers. Examples of micro-operation include shift, load, clear, increment, count, etc.

5. If a computer has more than one processor, it is called __________ . [S.S.C. Online CHSL (T-1) 19.01.2017 (Shift-1)]

(a) Uniprocessor
(b) Multiprocessor
(c) Dual Processor
(d) Quad-core processor

Correct Answer: (b) Multiprocessor

Solution:A multiprocessor is a data processing system that can execute more than one program or more than one arithmetic operation simultaneously. It is also known as a multiprocessing system. Multiprocessor uses more than one processor and is similar to multiprogramming, which allows multiple threads to be used for a single procedure.

6. Which type of storage device is a hard disk? [S.S.C. Online CHSL (T-I) 05.08.2021 (Shift-III)]

(a) Secondary
(b) Tertiary
(c) Off-line
(d) Primary

Correct Answer: (a) Secondary

Solution:A hard disk is a secondary storage device attached to a computer. Secondary storage is memory that is stored external to the computer. It is mainly used for the permanent and long-term storage of programs and data. Hard Disk, CD, DVD, Pen/Flash drive, SSD, etc. are examples of secondary storage.

7. A hard disk is an example of which type of data storage device? [S.S.C. Online CHSL (T-1) 18.03.2020 (Shift-1)]

(a) Territiary Storage
(b) Secondary Storage
(c) Offline Storage
(d) Primary Storage

Correct Answer: (b) Secondary Storage

8. Data that is copied from an application is stored in _________ . [C.P.O. S.I. 4.06.2016 (Shift-1)]

(a) Driver
(b) Terminal
(c) Prompt
(d) Clipboard

Correct Answer: (d) Clipboard

Solution:The clipboard is a data buffer used for short-term data storage and/or data transfer between documents or applications used by cut, copy and paste operations and provided by the operating system.

9. In the context of memory size in computer data storage, one gigabyte is equal to how many megabytes? [S.S.C. Online CHSL (T-1) 18.03.2020 (Shift-1)]

(a) 1012 MB
(b) 32 MB
(c) 64 MB
(d) 1024 MB

Correct Answer: (d) 1024 MB

Solution:

In computer system, one megabyte equals to 1024 kilobytes. In other words, there are 1,048,576 bytes in I megabyte according to the binary system which computers use. So one gigabyte is equal to 1,073,741,824 bytes in base 2. This also means that there are 1,024 megabytes in one gigabyte in binary system.

10. Which of the following is used to protect objects in computer system, in the absence of more complete protection schemes? [S.S.C. Online Graduation Level (T-1) 11.09.2016 (Shift-1)]

(a) Digital certificate
(b) Digital signature
(c) Passwords
(d) Tokens

Correct Answer: (c) Passwords

Solution:Passwords are often used to protect objects in the computer system in the absence of more complete protection schemes. They can be considered a special case of either keys or capabilities. Passwords are the most common approach to authenticating user identity.
