S1. Ans.(a)


  • Gateway is a network node used for interfacing with another network that uses different protocol. It acts as a “gate” between two networks. It may be a router, firewall, server, or other devices that enables traffic to flow in and out of the network.
  • A bridge connects and passes packets between two network segments that uses the same communications protocol. It functions at the data link layer. It filters, forwards or floods an incoming frame based on the MAC address of that frame.




S2. Ans.(b)

Sol: A Supervisor Call is an instruction, sent to a processor, to direct for the transfer of computer control to the operating system’s supervisor program. These are used for performing operating system service which are controlled by the operating system itself or another running application. Operating system is called the overseer and supervisor of all computer activity.


S3. Ans (d)

Sol. Assembly language, is a low-level programming language for a computer, or other programmable device. With the help of Assembler, assembly language is converted into machine code.


S4. Ans.(b)


  • A Queue is a linear structure in which one end is always used to insert data and the other is used to remove data. The order is First In First Out (FIFO).
  • Circular Queue is a linear data structure in which the last position is connected back to the first position to make a circle. The order is FIFO. It is also called ‘Ring Buffer’. Using the circular queue, we can make use of the spaces in front of the queue to store new values.
  • A Double-Ended queue (dequeue) is an abstract data structure that allows inserting or deleting from the both front (head) or back (tail). It is also called as Head-Tail linked list.


S5. Ans (d)

Sol.  Main memory works in conjunction with CPU.



S6. Ans.(b)

Sol. ALL_TAB_COLUMNS is used to describe the columns of the tables, views, and clusters accessible to the current user in the database.



S7. Ans.(a)

Sol. White Box testing deals with the internal structure, design and implementation of the item by the tester. Tester deeply understands the inner workings of the system or system component being tested. White Box testing is also called as Structural, Transparent Box, Code-Based, Glass box, Open box or Clear box testing.


S8. Ans.(c)

Sol. JK FF is different, in context of their outputs. In JK FF when input is J=K=1, then FF comes  in TOGGLE state. In this state, it will switch the output only one time in every clock cycle from one state to another state.



S9. Ans (d)


  • In a Cold booting process, hardware is completely reset and reloaded into the operating system, causing an initial boot of the machine. It is also known as hard booting.
  • In Warm booting process, system regains its initial state without hampering the power source. It is also known as Soft booting.

In Cold booting, temporary memory is also reset after the power interrupt but in Warm booting memory remains intact after reboot. Warm booting is done when program fails to respond and system frizzes in between a session and when system doesn’t respond to warm booting then cold booting is done.



S10. Ans (d)

Sol.  Firmware is programmed on a hardware device to provide the necessary instructions for how the device communicates with the other computer hardware. It is added at the time of manufacturing and stored in non-volatile memory devices such as ROM, EPROM, or flash memory.
