Computer Fundamentals and System Concepts Questions
-
Address bus
-
Control bus
-
Data bus
-
Memory bus
-
Both (1) and (2)
B
Correct answer
Explanation
Yes, the control bus carries the commands from the CPU.
-
Address bus
-
Control bus
-
Data bus
-
Memory bus
-
None of the above
A
Correct answer
Explanation
The Address bus carries the information about the devices which are going to communicate with CPU.
-
CISC (Complex Instruction Set Computer) emphasis on hardware.
-
RISC (Reduced Instruction Set Computer) emphasis on software.
-
RISC software based instruction set has more then one clock to execute the micro program.
-
CISC includes multi-clock complex instructions.
-
None of the above
E
Correct answer
Explanation
All of the above are true.
-
Pentium
-
Pentium II
-
MIPS
-
Intel 386
-
All of the above
E
Correct answer
Explanation
Yes, all of the above are true.
-
It has relatively few instructions.
-
It has relatively few addressing modes.
-
It has fixed length instructions.
-
It has a single cycle instruction execution.
-
None of the above
E
Correct answer
Explanation
All of the above are the characteristics of RISC (Reduced Instruction Set computer) processor.
-
linker
-
relocation
-
object file program
-
loader
-
new()
D
Correct answer
Explanation
It is an operating system utility that copies programs from a storage device to main memory, where they can be executed.
-
SPARC assembler
-
MASM assembler
-
Interpreter
-
Compiler
-
Byte code verifier
A
Correct answer
Explanation
It is an open set of technical specifications that any person or company can license and use to develop microprocessors and other semiconductor devices based on published industry standards.
-
configuration
-
CMOS
-
POST
-
ROM
C
Correct answer
Explanation
POST (Power-On Self-Test) is the process that checks if essential peripheral devices are attached and operational during boot. Configuration is a process, CMOS is memory chip, ROM is read-only memory.
-
files
-
folders
-
drives
-
systems
D
Correct answer
Explanation
File systems organize contents hierarchically using drives (like C:), folders (directories) for grouping, and individual files. 'Systems' is not a structural element in file organization - it's an abstract concept, not a container or item.
-
windows is an example of a command-driven environment
-
windows can be resized and repositioned on the desktop
-
more than one window can be open at a time
-
toolbars and scrollbars are features of windows
A
Correct answer
Explanation
Windows is a graphical user interface (GUI) environment where users interact with windows, icons, menus, and pointing devices. Command-driven environments like DOS require typing text commands, which is not how Windows operates.
-
modifies its program code each time it attaches itself to another program or file
-
is a malicious-logic program that copies itself repeatedly in memory or on a disk drive until no memory or disk space remains
-
a malicious-logic program that hides within or looks like a legitimate program
-
infects a program file, but still reports the size and creation date of the original, uninfected program
A
Correct answer
Explanation
A polymorphic virus changes its code each time it infects a new file, making it difficult for antivirus programs to detect through signature matching. This distinguishes it from other malware types like worms (which replicate repeatedly) or Trojan horses (which hide in legitimate programs). The constant code mutation is its defining characteristic.
B
Correct answer
Explanation
During the boot process, the BIOS (Basic Input/Output System) is responsible for initializing hardware and searching for system files required to load the operating system. The CPU executes instructions but doesn't search for files, while CD and DVD are storage media that may contain system files but don't actively search for them.
-
providing a way for the user to interact with the computer
-
managing the Central Processing Unit (CPU)
-
managing memory and storage
-
enabling users to perform a specific task such as document editing
D
Correct answer
Explanation
The operating system manages hardware (CPU), memory, storage, and provides user interaction interfaces. However, enabling users to perform specific tasks like document editing is the function of application software (like Word processors), not the OS itself. The OS provides the platform and resources for applications to run.
-
action
-
event
-
interrupt
-
activity
C
Correct answer
Explanation
An interrupt is a hardware signal sent to the CPU that indicates a device needs immediate attention, causing the CPU to suspend its current operations and handle the request. Events and activities are broader concepts, while an action is a general term for something that happens - none specifically describe this hardware signaling mechanism.
-
application programming interfaces (APIs)
-
complimentary metal-oxide conductors (CMOS)
-
device drivers
-
bootstrap loaders
A
Correct answer
Explanation
Application Programming Interfaces (APIs) are sets of defined methods and protocols that allow software applications to request services from the operating system. CMOS is a type of semiconductor technology, device drivers are specific hardware interface programs, and bootstrap loaders are programs that initiate the boot process.
