Correct Answer: C
The Control Unit (CU) fetches, decodes, and translates program instructions from memory, orchestrating execution across other CPU registers and units.
Q442.Processors of all computers, whether micro, mini or mainframe must have _____?
Correct Answer: D
Every functional computer processor architecture must contain a Control Unit (to direct flow), an ALU (for calculations), and access to primary storage (RAM) to hold active data.
Q443.Antivirus, WinZip, WinRAR and disk defragmenter are the examples of ________?
Correct Answer: C
Utility programs are system software components designed to analyze, configure, optimize, or maintain a computer system, such as backup, compression, or defragmentation tools.
Q444.Which one of the following is the bridge between the user and hardware. It is also called the Resource Manager?
Correct Answer: A
The Operating System (OS) is the intermediary interface between user software and hardware, acting as a resource manager to coordinate hardware allocations (CPU, memory, files).
Q445.Computer's performance is influenced by _____?
Correct Answer: D
A computer system's speed and throughput depend directly on the processor clock speed, the width of the system bus (transfer rate), and memory latency.
Q446.Which option is used to copy formatting from one place and apply it to another?
Correct Answer: C
The Format Painter tool allows users to copy all of the formatting (font, size, color, alignments) of selected text or objects and apply it elsewhere.
Q447.All hardware devices are attached directly or indirectly with ______?
Correct Answer: A
The Motherboard serves as the primary printed circuit board that directly or indirectly physically connects and links all computer hardware components.
Q448.What type of device is a computer mouse?
Correct Answer: A
A computer mouse is a pointing, handheld hardware input device used to send spatial coordinates and selection inputs to a computer.
Q449.In Word, the default alignment for paragraphs is_________?
Correct Answer: A
By default, Microsoft Word applies left-alignment (flush left margin with a ragged right margin) to newly typed paragraphs.
Q450.If a person deliberately damages data or deletes data from a computer, then this is called ______?
Correct Answer: B
Sabotage refers to the intentional, malicious destruction, damage, or deletion of computer data, hardware, or network services.
Q451.Data is transferred from one place to another through ______?
Correct Answer: A
Transmission media (cables, optical fibers, or wireless radio frequencies) provides the physical pathway to transfer data across systems.
Q452.A set of _____ used to write a computer program.
Correct Answer: A
A computer program consists of a structured set of instructions, collectively referred to as codes, written using programming languages.
Q453.The selection tools are used to crop/cut an area from a shape or a/an _____?
Correct Answer: B
In graphic editing software, selection tools isolate parts of an image or shape so they can be cut, cropped, or formatted independently.
Q454.Which modules is not part of C programming?
Correct Answer: C
A converter is not a standard program compilation component; C relies on an Editor (writing), Compiler (object generation), and Linker (executable generation).
Q455.Which are special non-printed character used to control printing on the output device?
Correct Answer: A
Escape sequences are special non-printing character sequences (beginning with backslash) used to control formatting on display or print outputs.
Q456.Virtual memory typically located on/in ____?
Correct Answer: D
Virtual memory is a resource allocation technique that utilizes partition space or files directly on the hard drive or solid-state drive.
Q457.Which is a chip that can the erased and reprogrammed on the motherboard?
Correct Answer: A
EEPROM (Electrically Erasable Programmable Read-Only Memory) can be electrically erased and reprogrammed byte-by-byte while installed.
Q458.The operation of arithmetic logic unit is directed by _____?
Correct Answer: A
The Control Unit (CU) coordinates and directs the data-processing operations of the Arithmetic Logic Unit (ALU).
Q459.CPU includes all of the following components expect?
Correct Answer: D
The CPU contains the ALU, Control Unit, and high-speed registers, but primary storage (RAM/ROM) is external to the core processor chip.
Q460.Which is a small memory device available in the CPU to store data temporarily?
Correct Answer: C
Registers are tiny, ultra-high-speed memory storage cells integrated directly inside the CPU to hold temporary values.
