  1. Adam Osborne produced the first portable computer.

  2. Ian Wilmut created the cloned sheep.


Which of the statements given above is/are correct?
  1.    Both A and B
  2.    A only
  3.    B only
  4.    Neither (A) nor (B)
 Discuss Question
Answer: Option A. -> Both A and B
Answer: (a)
Adam Osborne was an American entrepreneur who was best known for creating the first commercially available portable computer, the Osborne 1, released in April 1981.
Ian Wilmut is best known as the leader of the research group that in 1996 first cloned a mammal from an adult somatic cell, a Finnish Dorset lamb named Dolly.
Question 122. Nano technology deals with objects with dimensions in the range of
  1.    10–9 m
  2.    10–3 m
  3.    10–6 m
  4.    10–12 m
 Discuss Question
Answer: Option A. -> 10–9 m
Answer: (a)
Nanotechnology (sometimes shortened to “nanotech”) is the manipulation of matter on an atomic and molecular scale.
Generally, nanotechnology works with materials, devices, and other structures with at least one dimension sized from 1 to 100 nanometres which is equal to 10–9 m.
Question 123. In MS-Excel, ______ provide a visual representation of the values in a worksheet.
  1.    Templates
  2.    Charts
  3.    Formulae
  4.    Views
 Discuss Question
Answer: Option B. -> Charts
Answer: (b)
In MS-Excel charts provide a visual representation of the values in a worksheet.
Question 124. In IT, associative memory is called as
  1.    Content addressable memory
  2.    Virtual memory
  3.    Cache memory
  4.    Main memory
 Discuss Question
Answer: Option A. -> Content addressable memory
Answer: (a)
Associative memory in computer organization is when memory is accessed through content rather than through a specific address. Associative memory is also known as associative storage, associative array or content-addressable memory, or CAM.
Associative memory is found on a computer hard drive and used only in specific high-speed searching applications.
Question 125. Processor’s speed of a computer is measured in
  1.    Baud
  2.    BPS
  3.    MIPS
  4.    Hertz
 Discuss Question
Answer: Option C. -> MIPS
Answer: (c)million instructions per second (MIPS) is a measure of a computer’s processor speed. Many reported IPS values have represented “peak” execution rates on artificial instruction sequences with few branches, whereas realistic workloads typically lead to significantly lower IPS values.
Question 126. ENIAC was
  1.    an memory device
  2.    an electronic calculator
  3.    an electronic computer
  4.    an engine
 Discuss Question
Answer: Option C. -> an electronic computer
Answer: (c)
ENIAC was the first electronic general-purpose computer. It was Turing-complete, digital, and capable of being reprogrammed to solve a full range of computing problems.
It was designed to calculate artillery firing tables for the United States Army's Ballistic Research Laboratory.
Question 127. ASCII stands for
  1.    American StandardComputerforinformation Interchange
  2.    American Special Computer for information Interaction
  3.    American Special Code for Information Interchange.
  4.    American Standard Code for Information Interchange.
 Discuss Question
Answer: Option D. -> American Standard Code for Information Interchange.
Answer: (d)
ASCII stands for The American Standard Code for Information Interchange, which is a character-encoding scheme originally based on the English alphabet that encodes 128 specified characters -
the numbers 0-9,
the letters a-z and A-Z,
some basic punctuation symbols,
some control codes that originated with Teletype machines, and
a blank space - into the 7-bit binary integers.
Question 128. Consider the following statementsregarding pan-India mobile tele network

  1. The Pan-India mobile tele-network was launched in Coimbatore.

  2. The aim of the initiative is to strengthen the spice farming community with the help of latest technologies.

  3. The purpose of the scheme is to get in direct touch with the spice farmers of the state who are the core section of the society.


Correct statement is/are:
  1.    1 and 3
  2.    1 and 2
  3.    2 and 3
  4.    1, 2 and 3
 Discuss Question
Answer: Option D. -> 1, 2 and 3
Answer: (d)
The Pan-India mobile Tele-network was launched in Coimbatore. Dr A. Jayathilak, Chairman, Spices Board India launched the programme at a farmers meet held at Tamil Nadu Agricultural University, Coimbatore.
Around 300 farmers across the state attended the programme where around 6000 farmers have already registered in the Tamil Nadu spices community. The purpose of the scheme is to get in direct touch with the spice farmers of the state who are the core section of the society.
Question 129. The popular search engine “Google” derives its name from the word “Googol”. What does the word mean ?
  1.    To crawl
  2.    To search
  3.    To index
  4.    The numeral one followed by a hundred zeros
 Discuss Question
Answer: Option D. -> The numeral one followed by a hundred zeros
Answer: (d)
Google derived its name from the word “googol”, a term coined by then nine-year-old Milton Sirotta, nephew of the American mathematician Edward Kasner.
The story goes, Kasner had asked his nephew to invent a name for a very large number - ten to the power of one hundred (the numeral one followed by 100 zeros), and Milton called it a googol.
Question 130. ______ involves traversing the entire file system, marking everything that can be accessed.
  1.    File system
  2.    Index pointer
  3.    Garbage collection
  4.    Stack pointer
 Discuss Question
Answer: Option C. -> Garbage collection
Answer: (c)
Garbage collection involves traversing the entire file system, marking everything that can be accessed. Then, a second pass collects everything that is not marked onto a list of free space.
Garbage collection for a disk-based file system, however, is extremely time-consuming and is thus seldom attempted. Garbage collection is necessary only because of possible cycles in the graph.
