Question 1251. A portable, personal computer, small enough to fit on your lap, is called a __________.
  1.    notebook computer
  2.    handheld computer
  3.    mainframe computer
  4.    desktop computer
  5.    super computer
 Discuss Question
Answer: Option A. -> notebook computer
Answer: (a)
Question 1252. In latest generation computers, the instructions are executed
  1.    Parallel only
  2.    Sequentially only
  3.    Both sequentially and parallel
  4.    All of above
  5.    None of these
 Discuss Question
Answer: Option C. -> Both sequentially and parallel
Answer: (c)
In the latest generation computers, the instructions are executed Both sequentially and in parallel.
In computer science, an instruction is a single operation of a processor defined by the processor instruction set. The size or length of an instruction varies widely, from as little as 4-bits in some microcontrollers to many as multiples of bytes in some very long instruction word (VLIW) systems.

Question 1253. Which is a volatile memory :
  1.    ROM
  2.    BIOS
  3.    PROM
  4.    RAM
  5.    None of The Above
 Discuss Question
Answer: Option D. -> RAM
Answer: (d)
Volatile memory is a type of storage whose contents are erased when the system's power is turned off or interrupted. An example of volatile memory is RAM (Random Access Memory).
When you are working on a document, it is kept in RAM. If the computer you're using is disconnected from power, your work is lost because it was not stored in permanent (non-volatile) memory. For this reason, we recommend saving your documents or other data to a non-volatile storage medium, such as a hard drive, SSD, or USB stick.

Question 1254. A computer system that is old and perhaps not satisfactory is referred to as a(n)
  1.    Ancient system
  2.    Historical system
  3.    Age old system
  4.    Legacy system
  5.    Legal system
 Discuss Question
Answer: Option D. -> Legacy system
Answer: (d)
A legacy system is outdated computing software and/or hardware that is still in use. The system still meets the needs it was originally designed for but doesn’t allow for growth. What a legacy system does now for the company is all it will ever do. A legacy system’s older technology won’t allow it to interact with newer systems.
Question 1255. Which is a valid program to access the internet:
  1.    Access
  2.    Front Page
  3.    Netscape
  4.    None of The Above
 Discuss Question
Answer: Option C. -> Netscape
Answer: (c)
An Internet browser was first introduced as Mosaic Netscape 0.9 on October 13, 1994, Netscape was popular during the early 1990s and in a browser war with Microsoft Internet Explorer. The use of Netscape declined in the late 1990s, which led to the open source Mozilla project and Netscape's acquisition on November 24, 1998, by AOL for $4.2 billion.
Question 1256. A Page Fault occurs:
  1.    When the Page is not in Memory
  2.    When the Page is in the Memory
  3.    When the process is in the ready state
  4.    None of The Above
 Discuss Question
Answer: Option A. -> When the Page is not in Memory
Answer: (a)
A page fault is a type of exception raised by computer hardware when a running program accesses a memory page that is not currently mapped by the memory management unit (MMU) into the virtual address space of a process
Question 1257. BIOS stands for:
  1.    Basic Input Output Software
  2.    Basic Input Output System
  3.    Basic Input Output Standards
  4.    None of The Above
 Discuss Question
Answer: Option B. -> Basic Input Output System
Answer: (b)
Question 1258. Word Length of a Personal Computer is ______:
  1.    4 Bits
  2.    8 Bits
  3.    16 Bits
  4.    None of The Above
 Discuss Question
Answer: Option B. -> 8 Bits
Answer: (b)
The Word length of a Personal Computer is 8 bits.
The most common processors are/were 8-bit, 16-bit, 32-bit or 64-bit. These are the WORD lengths of the processor. Actually, half of a WORD is a BYTE, whatever the numerical length is. Ready for this, half of a BYTE is a NIBBLE. A byte may have more than or fewer than 8 bits. The term 'word' is used to describe the number of bits processed at a time by a program or operating system. So, in a 16-bit CPU, the word length is 16 bits. In a 32-bit CPU, the word length is 32 bits.
The hardware registers in a computer machine are word-sized. ... In this context, a word is a unit that a machine uses when working with memory. For example, on a 32-bit machine, the word is 32 bits long and on a 64 bit is 64 bits long. The word size determines the address space.

Question 1259. A ——— is an electronic device that process data, converting it into information.
  1.    computer
  2.    processor
  3.    case
  4.    stylus
  5.    None of these
 Discuss Question
Answer: Option B. -> processor
Answer: (b)
A processor is an integrated electronic circuit that performs the calculations that run a computer. A processor performs arithmetical, logical, input/output (I/O) and other basic instructions that are passed from an operating system (OS). Most other processes are dependent on the operations of a processor.
