51. What was the name of the first commercially available microprocessor chip
- A. Intel 8008
- B. Intel 8080
- C. Intel 4004
- D. Motorola 6809
Explanation: Intel 4004, released in 1971, is generally recognized as the first commercially available microprocessor. The 8008 and 8080 followed it, while the Motorola 6809 was introduced later.
Correct answer: Intel 400452. Distributed data entry means that data can be_____________?
- A. Entered at different locations where it originates
- B. Sent to different locations from a central place
- C. Accessed from different places know as distribution points
- D. Distributed through a network
Explanation: Distributed data entry means entering data at the locations where it is generated or collected, rather than sending all source data to one central entry point.
Correct answer: Entered at different locations where it originates53. Present day computers are based on __________?
- A. Along technology
- B. Hybrid technology
- C. Digital technology
- D. none of the above
Explanation: Modern general-purpose computers process information using discrete binary values, so they are based on digital technology. Hybrid technology combines analogue and digital methods but is not the basis of present-day computers generally.
Correct answer: Digital technology54. A computer is capable of performing almost any task provided, that it can be?
- A. Coded
- B. Memorised
- C. Analysed
- D. Reduced to a series of logical steps
Explanation: A computer can perform a task when that task can be expressed as a finite series of logical steps, or an algorithm. Merely memorising or analysing a task does not provide executable instructions.
Correct answer: Reduced to a series of logical steps55. A set of processes is deadlock if ?
- A. each process is blocked and will remain so forever
- B. each process is terminated
- C. all processes are trying to kill each other
- D. None of these
Explanation: Deadlock occurs when processes are permanently blocked because each is waiting for a resource held by another process in the set. Termination is not required for a deadlock; the processes typically remain active but unable to proceed.
Correct answer: each process is blocked and will remain so forever56. Type/s of Picture is/are?
- A. Vector
- B. Raster
- C. Master
- D. both A & B
Explanation: The two basic categories of computer graphics are raster images, made from pixels, and vector images, defined by lines and mathematical paths. Therefore both listed types are valid.
Correct answer: both A & B57. Picture is made of __________?
- A. Lines
- B. Dots
- C. Scratches
- D. Lightings
Explanation: A digital raster picture is built from tiny dots called pixels, with each pixel storing colour information. Lines and lighting may appear in an image, but they are not its basic raster units.
Correct answer: Dots58. In Computer, Bus is set of?
- A. Circuits
- B. Wires
- C. Registers
- D. Bulbs
Explanation: A bus is a group of electrical wires or pathways that carries data, addresses, and control signals between computer components. Registers and bulbs are components, not the definition of a bus.
Correct answer: Wires59. Which is known as temporary memory?
- A. ROM
- B. Hard Disk
- C. Registers
- D. Circuits
Explanation: CPU registers are very small, high-speed storage locations used temporarily while instructions are being processed. ROM and hard disks retain information, so they are not temporary storage.
Correct answer: Registers60. Temporary storage place for information in a computer is called:
- A. Back Up
- B. Buffer
- C. Binary file
- D. Data recorder
Explanation: A buffer is a temporary storage area that holds data while it is being transferred between devices or processes operating at different speeds. Backup and binary file describe storage or file forms, not this temporary holding area.
Correct answer: Buffer
