Solutions :
S1. Ans (b)
Sol. CD-RW (Compact Disc-Rewritable) is a digital optical disc storage format. A CD-RW disc is a compact disc that can be written, read arbitrarily many times, erased, and written again.
S2. Ans (d)
Sol. Firmware is programming that's written to the read-only memory (ROM) of a computing device. Firmware, which is added at the time of manufacturing, is used to run user programs on the device.
S3. Ans (c)
Sol. An Ad-Hoc Query is a query that cannot be determined prior to the moment the query is issued. It is created in order to get information when need arises and it consists of dynamically constructed SQL which is usually constructed by desktop-resident query tools.
S4. Ans (e)
Sol. A router is used to route data packets between different networks. It reads the information in each packet to tell where it is going. If it is destined for an immediate network it has access to, it will strip the outer packet (IP packet for example), readdress the packet to the proper Ethernet address, and transmit it on that network.
S5. Ans (c)
Sol. Dr Edgar F. Codd, after his extensive research on the Relational Model of database systems, came up with twelve rules of his own, which according to him, a database must obey in order to be regarded as a true relational database.
S6. Ans.(c)
Sol. 400% is the max. zoom percentage in PowerPoint.
S7. Ans.(d)
Sol. DBMS reduces data redundancy, provide a centralised manner to control of data and enabled data independence.
S8. Ans.(c)
Sol. Telnet is an application layer protocol used on the Internet or local area networks to provide a bidirectional interactive text-oriented communication facility using a virtual terminal connection.
S9. Ans.(a)
Sol. The CMOS is a physical part of the motherboard: it is a memory chip that houses setting configurations and is powered by the on board battery. The CMOS is reset and loses all custom settings in case the battery runs out of energy. Additionally, the system clock resets when the CMOS loses power.
S10. Ans.(a)
Sol. It is a machine independent language. It enables user to write programs in a language which resemble English words and familiar mathematical symbols.
S11. Ans. (d)
Sol. The analytical engine developed during first generation of computers used counter wheels as a memory unit
S12. Ans. (c)
Sol. Smallest to largest: Character, Field, Record, File, Database
S13. Ans. (b)
Sol. DRAM stands for Dynamic Random Access Memory.
S14. Ans. (a)
Sol. Cache Memory has shortest access time. Cache memory, also called CPU memory, is random access memory (RAM) that a computer microprocessor can access more quickly than it can access regular RAM
S15. Ans. (a)
Sol. EPROM is generally erased by using ultraviolet rays.
