Sol. Safari is a web browser
S2. Ans.(a)
Sol. F2 is a shortcut to rename selected object in MS windows 8 and higher versions
S3. Ans.(e)
Sol. In 1960's AT&T introduces its Dataphone, the first commercial modem. The first commercial modem made for converting digital computer data at analog signals for transmission across long distance networks
S4. Ans.(c)
Sol. IC were started to be in use from 3rd generation of computers. In third generation of computer, IC (Integrated circuits) was used as the electronic component for computers. The development of IC gave birth to a new field of microelectronics. The main advantage of IC is not only its small size but its superior performance and reliability than the previous circuits. It was first developed by T.S Kilby. This generation of computer has huge storage capacity and higher calculating speed.
S5. Ans.(b)
Sol. An API may be for a web-based system, operating system, database system, computer hardware, or software library. It is an acronym for Application Programming Interface. An API specifies how software components should interact and APIs are used when programming graphical user interface (GUI) components.
S6. Ans.(d)
Sol. BSODs appear when Microsoft Windows encounters a critical error it can’t recover from, requiring a reboot and possibly resulting in lost work. It stands for blue screen of death. Blue screens are generally caused by problems with your computer’s hardware or issues with its hardware driver software. A blue screen occurs when Windows encounters a “STOP Error.” This critical failure causes Windows to crash and stop working
S7. Ans.(b)
Sol. In digital imaging, a pixel, pel, or picture element is a physical point in a raster image, or the smallest addressable element in an all points addressable display device; so it is the smallest controllable element of a picture represented on the screen.
S8. Ans (e)
Sol. Walter Houser Brattain was an American physicist, along with John Bardeen and William Shockley, invented the point-contact transistor.
S9. Ans (a)
Sol. Diamond shaped figure is used to represent relationship in E-R diagram.
S10. Ans (d)
Sol. Updating is periodically adding, changing and deleting file records
S11. Ans (c)
Sol. Ctrl + D is the shortcut key to open font dialog box.
S12. Ans (c)
Sol. A gutter margin setting adds extra space to the side margin or top margin of a document that you plan to bind. A gutter margin helps ensure that text isn't obscured by the binding.
S13. Ans (a)
Sol. A codec is a device or computer program for encoding or decoding a digital data stream or signal.
S14. Ans (d)
Sol. General purpose computers can perform all those tasks.
S15. Ans (b)
Sol. Peer-to-peer (P2P) computing or networking is a distributed application architecture that partitions tasks or workloads between peers.
(d) 1- tier
(e) None of these
