Q301.A computer has a main memory of 960 Kbytes. What is the exact number of bytes contained in this memory?
Correct Answer: A
Memory is calculated based on 1 KB = 1024 bytes. Therefore, 960 Kbytes = 960 × 1024 bytes.
Q302.A salesman who travels by motorcycle needs a computer to record sales orders from the shops he visits. Which computer is most suitable?
Correct Answer: B
A tablet is highly portable, lightweight, compact, and features touch-screen input, making it highly ideal for field sales tasks.
Q303.Which of the following is an example of a processing device?
Correct Answer: B
A computer processor (CPU) is the primary processing device that executes instructions, performs calculations, and coordinates hardware.
Q304.Which of the following is an example of a hardcopy output device?
Correct Answer: B
A Printer is a hardcopy output device because it produces a physical, tangible copy of digital documents on paper.
Q305.Increasing which component will MOST directly improve performance when multiple application programs are running simultaneously?
Correct Answer: C
RAM (Random Access Memory) holds active programs and data. More RAM allows more programs to run simultaneously without system slowdown.
Q306.The F5 key on a standard computer keyboard is primarily used to?
Correct Answer: A
In browsers and folder explorers, pressing F5 refreshes or reloads the active window or webpage.
Q307.Which technique for deadlock recovery is generally easiest regarding CPU overhead?
Correct Answer: C
Terminating one or more deadlocked processes (Process Termination) is the simplest recovery method, despite losing some computational work.
Q308.Which of the following is NOT included in the Von Neumann computer architecture?
Correct Answer: D
The Von Neumann architecture features a unified memory for both data and instructions. Separate instruction and data buses belong to the Harvard architecture.
Q309.Which of the following is a type of computer program that is used to perform a specific task, such as creating a spreadsheet or editing an image?
Correct Answer: B
Application software is designed to perform specific user-oriented tasks, like creating spreadsheets or editing images, separate from core system software tasks.
Q310.Which feature in a word processor checks spelling and grammar?
Correct Answer: C
Spell Check is a standard office automation tool designed to identify and correct spelling and grammatical errors.
Q311.The clock speed of older computer CPUs was historically measured in ______?
Correct Answer: A
CPU clock speeds are measured in Hertz (Hz), historically in Megahertz (MHz) and modernly in Gigahertz (GHz).
Q312.Which of the following is a classic utility used for data compression?
Correct Answer: B
WinZip is a widely used file compression utility used to reduce the storage size of files and folders into archives.
Q313.Which memory architecture acts as a high-speed buffer between the CPU and the main memory (RAM)?
Correct Answer: A
Cache memory is ultra-fast SRAM buffer memory located very close to the CPU that stores frequently used instructions and data.
Q314.How many values can be returned from a function using a single return() statement in programming?
Correct Answer: C
A standard function return statement can return exactly one value or object (which could be a compound data structure like a tuple) back to the caller.
Q315.Which of the following mathematical operators has the highest precedence in standard programming?
Correct Answer: C
In standard mathematical and programming evaluation orders, multiplication (*) holds a higher precedence than addition (+) or subtraction (-).
Q316.When someone tells you that your computer does not have enough active memory, which of the following is being referred to?
Correct Answer: C
In standard computing, 'memory' refers to RAM (Random Access Memory), which temporarily holds active programs and data.
Q317.From the listed devices, which one is used to connect one computer to another?
Correct Answer: A
A modem (Modulator-Demodulator) converts analog signals to digital (and vice versa), enabling computers to connect and communicate over telephone lines or network media.
Q318.From the following listed devices, which one can store more data than the others?
Correct Answer: D
A Hard Disk Drive (HDD) or Solid State Drive (SSD) is the primary secondary storage device, holding vastly larger volumes of data (GBs to TBs) compared to RAM, ROM, or flash drives.
Q319.From the following, which one is the input device of a computer?
Correct Answer: A
A camera captures images and video data from the environment and inputs them into the computer system; monitors, printers, and speakers are output devices.
Q320.ROM is ____ memory?
Correct Answer: B
ROM (Read-Only Memory) is non-volatile permanent memory, keeping its startup and boot instructions intact even when the device is powered off.
