A systems programming language for microcomputers in the Intel family is
Answer: C
Correct answer: PL/M
PL/M - Programming Language for Microcomputers - was written by Gary Kildall in 1973 for Intel, and was the first high-level language aimed at microprocessors. CP/M and much of Intel’s own systems software were written in it.

Find odd one ?
Answer: B
Correct answer: Bug
A Trojan, a virus and a worm are all malicious programs, written deliberately to do harm. A bug is an unintentional mistake in a program - a defect, not an attack - so it is the odd one out.

Which among following is considered a volatile memory ?
Answer: C
Correct answer: RAM
RAM is volatile: it holds its contents only while power is applied, and everything in it is lost the moment the machine is switched off - which is why work must be saved to disk. ROM, a hard disk and a CD-ROM all retain their contents without power.

A single packet on a data link is known as
Answer: B
Correct answer: Frame
On a data link the unit that travels on the wire is a frame: the network-layer packet wrapped in a header carrying the hardware addresses of the two ends and a trailer carrying a checksum. The packet is the contents; the frame is the envelope the link layer puts round it.

In which generation of computers microprocessor was introduced ?
Answer: D
Correct answer: Fourth Generation
The fourth generation began in the early 1970s when a whole processor was put on a single chip - Intel’s 4004 in 1971 - making the microcomputer possible. The first three generations used vacuum tubes, transistors and small-scale integrated circuits respectively.

In virtual memory systems, Dynamic address translation
Answer: A
Correct answer: is the hardware necessary to implement paging
Dynamic address translation is the hardware - the memory management unit, with its page table and translation lookaside buffer - that converts each virtual address into a physical one as the instruction executes. Without it paging could not work, because every reference would have to be translated in software.

A terabyte comprises?
Answer: C
Correct answer: 1024 gigabyte
Each step up the scale multiplies by 1024, so \[ 1\ \text{TB} = 1024\ \text{GB} = 1024^2\ \text{MB} = 1024^3\ \text{KB} = 1024^4\ \text{bytes} \] which is 1,099,511,627,776 bytes. A terabyte is therefore 1024 gigabytes.

The digital computer accepts ____ data as input.
Answer: A
Correct answer: Binary
A digital computer works with two voltage levels only, so every input - a keystroke, a number, an image - must first be represented as a binary pattern of 0s and 1s. Text and numeric data are what the binary encodes, not a form the machine accepts directly.

Which of the following refers to the memory in your computer ?
Answer: A
Correct answer: RAM
RAM - random access memory - is the working memory that holds the programs and data currently in use, and it is what is meant when a machine is described as having so many gigabytes of memory. DSL is a broadband connection, USB a connection standard, and LAN a local network.
