Computer Fundamentals and System Concepts Questions
-
Authentication of users
-
Separation of privilege
-
Ease of use
-
File and I/O device access control
-
Least privilege
E
Correct answer
Explanation
In this principle applied in the design element of the operating system, each user and each program should operate by using the fewest privileges possible.
-
job scheduling
-
memory management
-
both (1) and (2)
-
none of these
C
Correct answer
Explanation
Operating systems perform multiple core functions. Job (process) scheduling decides which programs run and when. Memory management allocates, tracks, and frees RAM. An OS must handle both tasks simultaneously to function properly.
A
Correct answer
Explanation
Socket 370 was a processor socket design used by Intel for Celeron and some Pentium III processors. It featured 370 pins and was designed specifically for the Celeron processor line, not for the Pentium I, II, or III series which used different sockets.
-
Contents of the processors registers
-
Value of the variables
-
Current value of program counter (PC)
-
The process stack
-
The size of the process
E
Correct answer
Explanation
This information is not included inside a process which is an active entity and is more than a program code.
-
Perfective maintenance
-
Corrective maintenance
-
Adaptive maintenance
-
Incorrect maintenance
-
Sequential maintenance
C
Correct answer
Explanation
This type of software maintenance refers to changing the software to some new environment such as a different hardware platform or for use with a different operating system.
-
It can be in the form of mobile code.
-
It is written to reproduce itself.
-
It affects the executable programs on the disk.
-
It does not infect the boot sector of the hard disk.
-
It tries to spread itself to other machines.
D
Correct answer
Explanation
Some viruses infect the boot sector of the hard disk, so when the machine is booted, the virus gets to run.
-
OS
-
destructive program
-
useful hardware
-
useful software
B
Correct answer
Explanation
A virus is a malicious software program designed to replicate itself and spread to other computers, often causing harm to data, software, or system performance. It is specifically a destructive program, not an operating system or useful hardware/software.
-
Plug & Play
-
Creating Web pages
-
Multitasking
-
All of these
D
Correct answer
Explanation
Windows 98 supported all three features: Plug and Play for automatic hardware detection, built-in tools for creating web pages (FrontPad/Personal Web Server), and preemptive multitasking for running multiple applications. Therefore 'All of these' is correct.
-
Operating System
-
Application
-
Software
-
None of these
A
Correct answer
Explanation
The Operating System is responsible for all fundamental resource management including memory, CPU, processes, and devices. Applications run on top of the OS and request resources through it. Memory management is a core OS function, not handled by individual applications.
-
formatting
-
booting
-
downloading
-
uploading
B
Correct answer
Explanation
Booting is the process of loading the operating system into memory when a computer is powered on, derived from 'pulling oneself up by bootstraps'. Formatting erases disk contents, downloading/uploading involve data transfer over networks - none describe the OS loading process.
-
speed of super computers
-
speed of an internet connection
-
speed of a printer
-
resolution of an image
A
Correct answer
Explanation
FLOPS (Floating Point Operations Per Second) is a standard metric for measuring computational performance, specifically for supercomputers. It counts how many floating-point calculations a processor can perform in one second. Unlike other options: internet speed uses Mbps/Gbps, printers use PPM (pages per minute), and image resolution uses pixels or DPI.
-
compiler
-
system software
-
boot
-
interpreter
B
Correct answer
Explanation
System software (including the operating system and boot programs) is used to start the computer. A compiler translates code, an interpreter executes code, and boot is the process itself, not the program type.
-
software
-
interpreter
-
compiler
-
controller
A
Correct answer
Explanation
Software is the set of instructions that tells a computer how to perform a particular task. It includes programs, applications, and operating systems that enable the hardware to function. An interpreter and compiler are specific types of software that process code, while a controller is a hardware component that manages operations.
-
Hackers
-
Software pirates
-
Emulators
-
Debuggers
B
Correct answer
Explanation
Software piracy refers to the unauthorized copying, distribution, or modification of software. People who engage in these illegal activities are specifically called 'software pirates,' making option B correct. Hackers may break into systems, but that doesn't necessarily involve software piracy.
