Solutions
S1. Ans.(c)
Sol. In the
client-server system, microcomputers are commonly treated as client
computers due to their limited hardware configuration to handle and
process multiple tasks.
S2. Ans.(a)
Sol. In the gaming
console market, Microsoft launched its first foray named X-box that
is actually a video game console.
S3. Ans.(d)
Sol. Erasable
Programmable Read-Only Memory (EPROM) is a type of ROM from which the
stored data can be erased using ultraviolet rays.
S4. Ans.(d)
Sol. A computer
stores data in the binary form that is in the form of 0’s and 1’s.
S5. Ans.(b)
Sol. Second
generation computers designed in 1960s were based on transistors.
These computers were more reliable and faster than first generation
computers that were based on vacuum tubes.
S6. Ans.(a)
Sol. SSD is a
storage device that does not contain any moving parts, such as
spinning platters and heads; therefore, it is faster than hard disk
drive. An SSD uses transistors to store data. In SSD, the information
can be accessed immediately, because there is no latency time when
data is transferred.
S7. Ans.(c)
Sol. Compact
Disc-Recordable (CD-R) technology is known as Write Once-Read Many
(WORM) technology as data once written on these discs cannot be
erased.
S8. Ans.(b)
Sol. Motherboard
chipset controls data flow between a processor, RAM and cache, system
buses, and peripheral devices. Motherboards consist of two distinct
chipsets namely Northbridge and Southbridge. The Northbridge chipset
examines the communication and throughout speed between a processor,
memory, and graphic card. The Southbridge chipset examines serial and
parallel ports, USB support, and power management functions.
S9. Ans.(b)
Sol. Web socket is a
protocol-based communication system between a server and its clients.
It allows bidirectional communication between a Web browser and a Web
server with the help of Transmission Control Protocol (TCP)
connection.
S10. Ans.(c)
Sol. Modernizr is an
open-source JavaScript library that detects whether the features of
HTML5 and CSS3 are supported by a browser or not.
S11. Ans.(a)
Sol. Web hosting is
a service that allows organisations to make their own website
accessible through WWW. This service allows you to share the data on
the Web or the Internet by storing your Web page on the Internet.
S12. Ans.(a)
Sol. In HTML, you
can create a horizontal line on a Web page by using the <hr>tag.
The purpose of the <hr> tag is to separate paragraphs or
sections on a Web page.
S13. Ans.(b)
Sol. The GIF image
format was developed for CompuServe (an online information service)
before the Internet was invented. Covering an image to a GIF image
format is safe as no data is lost at the time of conversion.
S14. Ans.(a)
Sol. PARAM is a
series of supercomputers designed and assembled by the Centre for
Development of Advanced Computing (C-DAC) in Pune, India. The latest
machine in the series is the PARAM Kanchenjunga.
S15. Ans.(c)
Explanation: ACID
(Atomicity, Consistency, Isolation, and Durability) is a set of
properties of database transactions.
