Question 1

What is the capacity of super computers floppy disc?

Accepted Answer

Correct Option: (e) None of these. Option (e) None of these is the correct answer. Standard floppy disks (e.g., $3.5$-inch) have a typical capacity of $1.44 text{ MB}$ (Megabytes). The options provided ($400 text{ MB}$, $500 text{ MB}$, $600 text{ MB}$, $700 text{ MB}$) are capacities more commonly associated with CD-ROMs, not floppy disks. Supercomputers, despite their power, would not use floppy disks for significant storage, and their capacity would still be limited to standard floppy disk sizes if used. Therefore, the given capacities are incorrect for floppy disks.

Question 2

RAM is a ........ memory.

Accepted Answer

Correct Option: (c) internal. Option (c) internal is the correct answer. RAM (Random Access Memory) is physically located inside the computer system, typically on the motherboard, and is directly accessible by the CPU. This makes it an 'internal' component. While RAM is also considered 'main' memory (option d), 'internal' describes its physical placement within the system unit, distinguishing it from external storage.

Question 47

63. Which of the following can only have sequential access?

Accepted Answer

Correct Option: Tape. Magnetic 'Tape' is a sequential access medium; data must be read in order. Disks (hard, floppy, CD-ROM, DVD-ROM) are random access, allowing direct access to any data location. Thus, only tape has sequential access.

Question 48

64. When you save to ......., your data will remain intact even when the computer is turned off.

Accepted Answer

Correct Option: secondary storage device. To ensure data persists after power off, it must be saved to a 'secondary storage device' (e.g., HDD, SSD), which is non-volatile. RAM (primary storage) is volatile. The motherboard is a circuit board. Thus, secondary storage is correct.

Question 49

65. A CD-RW disk ........

Accepted Answer

Correct Option: can be erased and rewritten. CD-RWs are slower than internal disks. 'RW' means ReWritable, so it can be written multiple times, unlike CD-R. CD-RWs ($approx 700 text{ MB}$) hold significantly more data than floppy disks ($approx 1.44 text{ MB}$). Therefore, CD-RWs can be erased and rewritten, making option (d) correct.

Question 50

66. Which device can understand difference between data and programs?

Accepted Answer

Correct Option: Microprocessor. The 'Microprocessor' (CPU) executes program instructions and manipulates data according to those instructions, thus 'understanding' their distinct roles. Input/output devices and memory simply handle or store binary information without interpretation. Thus, the microprocessor is correct.

Question 51

67. Which of the following devices have a limitation that we can only read it but can not erase or modify it?

Accepted Answer

Correct Option: Compact disk. A 'Compact disk', specifically a CD-ROM (Read-Only Memory), is designed to be read-only and cannot be erased or modified by the user. Tape drives, hard disks, and floppy disks are all read/write devices. Thus, 'Compact disk' (CD-ROM) is the correct answer.

Question 52

68. Which of the following is the storage area within the computer itself which holds data only temporarily as the computer processes instructions?

Accepted Answer

Correct Option: main memory. 'Main memory' (RAM) is the volatile storage area where the CPU temporarily holds data and programs during active processing. A hard disk is permanent storage. The control unit manages operations. Read-only memory is for firmware. Thus, main memory is correct.

Question 53

69. If a memory chip is volatile, it will ...........

Accepted Answer

Correct Option: lose its contents if currents it turned off. A 'volatile' memory chip loses its contents when power is removed (currents turned off). Explosion is not related to volatility. Volatile memory stores both programs and data, and read/write capability isn't its definition. Thus, losing contents without power is the definition.

Question 54

33. Unit of storage capacity—

Accepted Answer

Correct Option: Byte. A byte is a unit of digital information, commonly $8$ bits, and a standard measure for storage capacity. A bit is the smallest unit, but byte is more practical for capacity. A bug is an error. A cubic meter measures physical volume. Thus, Byte is the most appropriate unit for storage capacity.

Question 55

48. Secondary storage ...........

Accepted Answer

Correct Option: does not require constant power. Secondary storage is non-volatile, meaning it retains data without constant power. It does use magnetic media (HDDs). Its purpose is to store for later retrieval. The number of types is arbitrary. Thus, not requiring constant power is a key characteristic.

Question 56

34. By firmware we understand ...........

Accepted Answer

Thus, both magnetic tape and discs store large data volumes. 'All of These' is incorrect as only (a) and (b) are specific options.

Question 58

36. The word 'memory' is related to ...........

Accepted Answer

Correct Option: Storage. Memory is a fundamental type of storage, encompassing both primary (RAM) and secondary (disk) storage. Logic and control relate to processing. Input is data entry. Therefore, memory is directly related to storage.

Question 59

37. The content of ........... are lost when the computer is turned off.

Accepted Answer

Correct Option: Memory. Memory, specifically volatile RAM, holds data and programs actively in use. Its contents are lost when power is removed, unlike non-volatile storage. Input and output are processes, not volatile storage. Storage is too broad a term. Thus, memory (RAM) is the correct answer.

Question 60

38. The most common type of storage devices are—

Accepted Answer

Correct Option: Magnetic. Magnetic storage (HDDs) has historically been and remains very common for bulk data due to cost-effectiveness. Flash (SSDs) is growing but magnetic still holds significant share. Persistent is a characteristic, optical is less common than magnetic/flash. Thus, magnetic is the most fitting.

Question 61

39. A disk's content that is recorded at the time of manufacture and that cannot be changed or erased by the user is—

Accepted Answer

Correct Option: Read only. Content recorded at manufacture and unchangeable by the user is characteristic of 'Read only' media like CD-ROMs. 'Memory only' is vague. 'Write only' is contradictory. 'Run only' refers to execution. Thus, 'Read only' is the precise description.

Question 62

40. Any data or instructions natural into memory of a computer is considered as ...........

Accepted Answer

Correct Option: information. Data and instructions, when in memory for processing, are collectively considered 'information'. Storage is the medium. Input is the entry process. Output is the result. Thus, 'information' best describes data/instructions in memory.

Question 63

41. CDs are of which shape?

Accepted Answer

Correct Option: Round. Compact Discs (CDs) are physically circular or 'Round' in shape. Square and rectangular are incorrect shapes. 'Information' is what is stored on a CD, not its physical form. Thus, 'Round' is the correct shape.

Question 64

42. The instructions for starting the computer are housed in—

Accepted Answer

Correct Option: ROM chip. The essential boot instructions (BIOS/UEFI firmware) are stored permanently in a Read-Only Memory (ROM) chip on the motherboard. RAM is volatile. CD-ROM is external media. Thus, the ROM chip is the correct location.
