In which of the following form, data is stored in computer ?
Answer: B
Correct answer: Binary
Every circuit in a computer distinguishes just two states - off and on, low and high - so all data is stored as binary patterns of 0s and 1s. Decimal, octal and hexadecimal are notations people use to write those patterns conveniently; hexadecimal is popular because one digit stands for exactly four bits.

Fragmentation of the file system
Answer: C
Correct answer: can be temporarily removed by compaction
Fragmentation leaves a file’s blocks scattered across the disk, so compaction (defragmentation) rewrites them contiguously and gathers the free space together. The relief is temporary: continued creation and deletion of files fragments the disk again.

Which among following is the lowest form of Computer Language ?
Answer: C
Correct answer: Machine Language
Machine language is the processor’s own binary code - the only form it can execute directly, with no translation of any kind. Assembly language is one step above it, replacing the binary with mnemonics that an assembler converts, and COBOL and Perl are high-level languages further removed still.

Which among following is not a low level language ?
Answer: C
Correct answer: COBOL
Machine language and assembly language are low-level: they work in terms of the particular processor’s instructions and registers. COBOL is a high-level language whose statements are written in English-like sentences and are translated by a compiler, so it is independent of any one machine.

A storage system for small amounts of data is
Answer: A
Correct answer: Magnetic card
A magnetic card carries a short stripe of magnetic material and so holds only a small quantity of data - an account number, an identifier, an expiry date. Tape holds vast amounts sequentially, and an optical mark reader is an input device rather than a storage medium.

A datum that indicates some important state in the content of input or output is
Answer: B
Correct answer: Sentinel
A sentinel is a value placed in the data stream to mark a significant point - most often the end of a list or a record - so that a loop can stop when it meets the sentinel instead of counting items. The null terminator ending a C string is the familiar example.

Answer: D
Correct answer: Basic Input Output System
