A personal computer is a small and low-cost, intended for personal use (or for use by a small group of individuals). 
The term personal computer describes desktop computers (desktops). It is often shortened to the acronym PC or microcomputer, 
whose meaning in English is a personal computer.
Question 2. The basic goal of computer process is to convert data into __________.
  1.    information
  2.    tables
  3.    files
  4.    graphs
  5.    None of these
Explanation:-
Answer: Option A. -> information
Answer: (a)
The basic goal of the computer process :
As a result, data processing refers to the act of converting raw data into usable information.
The data we enter is unprocessed, and the computer transforms it into valuable data.
Data manipulation by a computer is called data processing. It entails the translation of raw data into a machine-readable format, data flow via the CPU and memory to output devices, and output formatting or modification.
 
Question 3. Computers excel at
  1.    performing the same action(s) over and over the same way.
  2.    keeping track of large numbers of small details.
  3.    providing creative solutions to problems.
  4.    working in fractions of seconds.
  5.    All of these
Explanation:-
Answer: Option E. -> All of these
Answer: (e)
Excel is a tool for organizing and performing calculations on data. It can analyze data, calculate statistics, generate pivot tables, and represent data as charts or graphs.
Question 4. The benefit of using computers is that ________.
  1.    Computers are very fast and can store huge amounts of data
  2.    Computers provide accurate output even when input is incorrect
  3.    Computers are designed to be inflexible
  4.    All of these
  5.    None of these
Explanation:-
Answer: Option A. -> Computers are very fast and can store huge amounts of data
Answer: (a)
The benefit of using computers is that computers are very fast and can store huge amounts of data.
Magnetic tape drives, floppy disk drives and hard disk drives are all examples of backing storage devices. The Main Memory contains two types of memory chips called ROM and RAM which hold program instructions and data. Computers store and process data using binary numbers. 
There are two types of storage devices used with computers: a primary storage device, such as RAM, and a secondary storage device, like a hard drive. Secondary storage can be removable, internal, or external storage. 
Computers have both advantages and disadvantages. On one hand, they allow us to access the wealth of information that is available on the internet. They also allow us to analyze massive amounts of data very quickly, saving both time and money.
Question 5. A thread is a______ :
  1.    lightweight process where the context switching is low
  2.    lightweight process where the context switching is high
  3.    is used to speed up paging
  4.    None of The Above
Explanation:-
Answer: Option A. -> lightweight process where the context switching is low
Answer: (a)
A thread is usually defined as a lightweight process because an operating system (OS) maintains smaller data structures for a thread than for a process.
Question 6. Microcomputer hardware consists of three basic categories of physical equipment __________.
  1.    keyboard, monitor, hard drive
  2.    system unit, input/output, memory
  3.    system unit, input/output, secondary storage
  4.    system unit, primary storage, secondary storage
  5.    None of these
Explanation:-
Answer: Option B. -> system unit, input/output, memory
Answer: (b)
Question 7. Super computer developed by Indian scientists
  1.    Param
  2.    Super30l
  3.    Compaq Presario
  4.    Cray YMP
  5.    Blue Gene
Explanation:-
Answer: Option A. -> Param
Answer: (a)
Param is a supercomputer developed by Indian Scientists.
Supercomputer PARAM 8000 (made by the Centre for Development of Advanced Computing (C-DAC)) was launched on July 1, 1991, and is considered India's first supercomputer. It was indigenously built in 1991 by C-DAC and was replicated and installed at ICAD Moscow in 1991 under Russian collaboration.
PARAM is a series of supercomputers designed and assembled by the Centre for Development of Advanced Computing (C-DAC) in Pune, India. The latest machine in the series is the PARAM ISHAN.
Bhatkar is best known as the architect of India's national initiative in supercomputing where he led the development of Param supercomputers. He developed the first Indian supercomputer, the PARAM 8000, in 1991 and later the PARAM 10000 in 1998.
Vijay Pandurang Bhatkar, 70, has been appointed as the new Vice-Chancellor of Nalanda University, Rajgir, in Bihar. He is a technocrat who is popularly known as the father of the Indian Supercomputer.

Question 10. Multi-programming systems________:
  1.    Are easier to develop than single programming systems
  2.    Execute each job faster
  3.    Execute more jobs in the same time
  4.    None of The Above
Explanation:-
Answer: Option C. -> Execute more jobs in the same time
Answer: (c)
Multitasking has the same meaning as multiprogramming but in a more general sense, as it refers to having multiple running at the same time. This term is used in modern operating systems when multiple tasks share a common processing resource.
