Solution :

S1. Ans.(a)
Sol. Microsoft provided Operating System to IBM PC DOS.

S2. Ans.(b)
Sol. Earliest computers used Machine language.

S3. Ans.(a)
Sol. The Analytical Engine was a proposed mechanical general-purpose computer designed by English mathematician and computer pioneer Charles Babbage. It was first described in 1837 as the successor to Babbage's difference engine, a design for a mechanical computer.

S4. Ans.(c)
Sol. In second generation, magnetic cores were used as primary memory. In this generation assembly language and high-level programming languages like FORTRAN, COBOL were used.

S5. Ans.(a)
Sol. The first electronic digital computer contained electronic valves.

S6. Ans. (a)
Sol. The terms "online" and "offline" have specific meanings in regard to computer technology in which "online" indicates a state of connectivity, while "offline" indicates a disconnected state.

S7. Ans. (d)
Sol.  Video Graphics Array (VGA) refers specifically to the display hardware first introduced with the IBM PS/2 line of computers, but through its widespread adoption has also come to mean either an analog computer display standard, the 15-pin D-subminiature VGA connector or the 640x480 resolution itself.

S8. Ans. (d)
Sol.  Ctrl + Shift + P is the shortcut key to access the font size tool on font dialog box.

S9. Ans. (e)
Sol.  IP, TCP and Gopher all are protocols governing the internet. IP-Internet Protocol, TCP- Transmission Control Protocol

S10. Ans. (c)
Sol.  Visual FoxPro is a data-centric, object-oriented, procedural, programming language produced by Microsoft. It is derived from FoxPro (originally known as FoxBASE) which was developed by Fox Software beginning in 1984.

S11. Ans. (c)
Sol. Java Database Connectivity (JDBC) is an application programming interface (API) for the programming language Java, which defines how a client may access a database. It is part of the Java Standard Edition platform, from Oracle Corporation.

S12. Ans. (e)
Sol. Modifier keys include Alt, Ctrl, Shift. A modifier key is a key that modifies the action of another key when the two are pressed together.

S13. Ans. (b)
Sol. The bit rate is quantified using the bits per second unit

S14. Ans. (d)
Sol. except Wide Area Web all other terms are related to the given context.

S15. Ans. (d)
Sol. Write through is a storage method in which data is written into the cache and the corresponding main memory location at the same time. The cached data allows for fast retrieval on demand, while the same data in main memory ensures that nothing will get lost if a crash, power failure, or other system disruption occurs.
