Answer: Option C. -> Arithmetic Logic Unit
Answer: (c)ALU stands for arithmetic-logic unit which is the part of a computer processor (CPU) that carries out arithmetic and logic operations on the operands in computer instruction words. It is a fundamental building block of the central processing unit found in digital computers.

Answer: Option A. -> multiplication
Answer: (a)The ‘AND’ gate in computers has basic application of multiplication. It has two or more inputs and one output. An ‘AND’ gate produces an output of 1 if all the inputs are 1 if any of the inputs is zero then it produces an output of zero.

Answer: Option B. -> Stack
Answer: (b)
In computer science, LIFO refers to the way items stored in some types of data structures are processed. A LIFO structure can be illustrated with the example of a stack of trays.
The term in computing generally refers to the abstract principles of list processing and temporary storage, particularly when there is a need to access the data in limited amounts, and in a certain order.

Answer: Option A. -> three years
Answer: (a)
Finance Minister in his Budget speech on 28th February 2011 said that “Five years ago, we took an initiative to introduce a modern and people-friendly e-stamping facility in the country. Only six states have introduced this system so far.
I propose to launch a new scheme with an outlay of Rs 300 crore to provide assistance to States to modernise their stamp and registration administration and roll out stamping in all the districts in the next three years.”

Answer: Option A. -> Meta data
Answer: (a)
In a Database Management System (DBMS), the content and the location of the data is defined by the Metadata. Metadata is “data about data”.
It assists in resource discovery by allowing resources to be found by relevant criteria, identifying resources, bringing similar resources together, distinguishing dissimilar resources, and giving location information.

Answer: Option D. -> All of the above
Answer: (d)An address consists of an offset, a base register and an index register.

Answer: Option A. -> Piggybacking
Answer: (a)
The technique of temporarily delaying outgoing acknowledgements so that they can be hooked onto the next outgoing data frame is known as piggybacking.
The principal advantage of using piggybacking over having distinct acknowledgement frames is a better use of the available channel bandwidth.

Answer: Option C. -> Router
Answer: (c)
The third-lowest layer of the OSI Reference Model is the network layer. It is responsible for packet forwarding including routing through intermediate routers. Routers forward data packets between computer networks.
A data packet is forwarded from one router to another through the networks that constitute the internetwork until it reaches its destination node.

Answer: Option B. -> Registers
Answer: (b)
The control unit maintains order within the computer system and directs the flow of traffic(operations) and data.
The arithmetic-logic unit (ALU) performs all arithmetic operations (addition, subtraction, multiplication, and division) and logic operations. These two have special-purpose storage called Registers.

Answer: Option C. -> Pune
Answer: (c)PARAM is a series of supercomputers designed and assembled by the Centre for Development of Advanced Computing (C-DAC) in Pune, India. The latest machine in the series is the PARAM Yuva. PARAM 8000, which was installed in 1991, is considered as India’s first supercomputer.
