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.
