Question 5

Following is valid Linux based Shell
A)c-shell
B)d-shell
C)k-shell
D)none of above

Accepted Answer

c-shell is a valid Linux-based shell, known for its C-like syntax.

Question 6

Shell is the exclusive feature of
A)unix
B)dos
C)system software
D)application software

Accepted Answer

The shell is a unique feature of Unix, serving as a command-line interface that allows users to interact with the operating system by executing commands.

Question 7

Operating system is
A)hardware
B)software which manage resources of the system
C)software which performs computation
D)none

Accepted Answer

Operating systems are software that manage computer hardware and software resources, providing common services for computer programs.

Question 8

To increase the response time and throughput, the kernel minimizes the frequency of disk access by keeping a pool of internal data buffer called
A)pooling
B)spooling
C)buffer cache
D)swapping

Accepted Answer

The kernel minimizes the frequency of disk access and improves system performance by keeping a pool of internal data buffers known as the buffer cache. This allows for the temporary storage of data being read from or written to the disk, reducing the need for frequent disk accesses.

Question 9

At start of process execution, STDOUT & STDERR
A)point to current terminal device
B)are closed
C)point to special files on the system
D)none of the above

Accepted Answer

At the start of process execution, STDOUT (standard output) and STDERR (standard error) are by default connected to the current terminal device. This allows the process to output messages and errors to the terminal where it was started, unless explicitly redirected.

Question 10

wtmp and utmp files contain:
A)temporary system data
B)user login-logout log
C)the user's command execution log
D)the user's su and sudo attempts

Accepted Answer

The wtmp and utmp files are used to record user logins and logouts, making choice B correct. The utmp file keeps track of the current login state of users, while the wtmp file logs all logins and logouts.

Question 11

Which is the core of the operating system?
A)shell
B)kernel
C)commands
D)script

Accepted Answer

The kernel is the core part of the operating system, managing system resources and facilitating interactions between hardware and software components.

Question 12

ILP32 stands for
A)32 bit integer, long & pointer
B)32 bit integrated long & pointer
C)32 bit intelligent long & pointer
D)32 bit long & pointer

Accepted Answer

ILP32 stands for 32-bit Integer, Long, and Pointer, indicating that these data types are all 32 bits in length in this programming model.

Question 13

Single Unix Specification Version 2 provides enhanced support for
A)16 bit unix
B)32 bit unix
C)64 bit unix
D)8 bit unix

Accepted Answer

Single Unix Specification Version 2 provides enhanced support for 64-bit Unix systems, allowing for larger address spaces and improved performance on modern hardware architectures.

Question 14

Under UNIX the key board is the default input device and the monitor is the default output device

Accepted Answer

In UNIX systems, the keyboard is typically considered the default device for input (where users type commands), and the monitor is considered the default device for output (where the system displays results and messages).

Question 15

Which among the following interacts directly with system hardware?
A)shell
B)commands
C)kernel
D)applications

Accepted Answer

The kernel is the core component of an operating system that interacts directly with the system hardware, managing resources and facilitating communication between hardware and software components.

Question 16

Applications communicate with kernel by using:
A)system calls
B)c programs
C)shell script
D)shell

Accepted Answer

Applications communicate with the kernel through system calls, which are a set of programmed instructions that allow a software program to request a service from the kernel of the operating system.

Question 17

SVR4 was developed by
A)sun microsystems
B)at&t
C)university of berkeley
D)sun and at&t jointly

Accepted Answer

SVR4, or System V Release 4, was developed jointly by Sun Microsystems and AT&T as a way to combine features from both AT&T's System V and Sun's SunOS, among other contributions.

Question 18

Which of these is not a Unix Flavor?
A)bsd
B)mac
C)aix
D)irix

Accepted Answer

Mac OS, while it is based on a Unix-like structure (specifically, it's derived from BSD), is not typically referred to as a "Unix flavor" in the same way that BSD, AIX, and IRIX are. These are direct derivatives or versions of Unix, whereas Mac OS (especially modern versions, known as macOS) is a commercial operating system developed by Apple Inc. that incorporates elements from Unix but also includes proprietary components.

Question 19

Which of the following statement is FALSE ?
A)unix supports multiple users
B)linux is an open source operating system and the source code is shared
C)shell takes care of inter process communication
D)shell provides the feature of i/o redirection

Accepted Answer

The false statement is C) shell takes care of inter-process communication. This task is actually managed by the operating system's kernel, not the shell. The shell is primarily a command interpreter that provides a user interface for access to operating system services. Inter-process communication mechanisms are provided by the operating system's kernel to allow processes to communicate and synchronize their actions.

Question 20

Which of the following UNIX flavor is from IBM?
A)bsd
B)solaris
C)hp-ux
D)aix

Accepted Answer

AIX is a UNIX operating system developed by IBM.
