Q-4)   Super computer developed by Indian scientists

(a)

(b)

(c)

(d)

(e)

Explanation:

Param is a supercomputer developed by Indian Scientists.

Supercomputer PARAM 8000 (made by the Centre for Development of Advanced Computing (C-DAC)) was launched on July 1, 1991, and is considered India's first supercomputer. It was indigenously built in 1991 by C-DAC and was replicated and installed at ICAD Moscow in 1991 under Russian collaboration.

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 ISHAN.

Bhatkar is best known as the architect of India's national initiative in supercomputing where he led the development of Param supercomputers. He developed the first Indian supercomputer, the PARAM 8000, in 1991 and later the PARAM 10000 in 1998.

Vijay Pandurang Bhatkar, 70, has been appointed as the new Vice-Chancellor of Nalanda University, Rajgir, in Bihar. He is a technocrat who is popularly known as the father of the Indian Supercomputer.


Q-5)   The basic goal of computer process is to convert data into

(a)

(b)

(c)

(d)

(e)

Explanation:

As a result, data processing refers to the act of converting raw data into usable information.

The data we enter is unprocessed, and the computer transforms it into valuable data.

Data manipulation by a computer is called data processing. It entails the translation of raw data into a machine-readable format, data flow via the CPU and memory to output devices, and output formatting or modification.

Q-6)   A __________ computer is a large and expensive computer capable of simultaneously processing data for hundreds or thousands of users

(a)

(b)

(c)

(d)

(e)

Explanation:

Mainframes are a type of computer that generally are known for their large size, amount of storage, processing power and high level of reliability. They are primarily used by large organizations for mission-critical applications requiring high volumes of data processing.

In general, there are a few characteristics of mainframes that are common among all mainframe vendors: Nearly all mainframes have the ability to run (or host) multiple operating systems. Mainframes can add or hot swap system capacity without disruption.

Mainframes are designed to handle very high volume input and output (I/O) and emphasize throughput computing. A single mainframe can replace dozens or even hundreds of smaller servers.


Q-7)   Which of the following are computers that can be carried around easily?

(a)

(b)

(c)

(d)

(e)

Explanation:

Laptops are computers that can be carried around easily.


Q-8)   _______sent data or instructions to the computer :

(a)

(b)

(c)

(d)

Explanation:

An input device is any hardware component that allows users to enter data and instructions into a computer.


Q-9)   Which one is the Low Level Language:

(a)

(b)

(c)

(d)

(e)

Explanation:

A low-level language is a programming language that provides little or no abstraction of programming concepts and is very close to writing actual machine instructions. Two examples of low-level languages are assembly and machine code.

Q-12)   A central computer that holds collections of data and programs for many PCs, workstations and other computers is a(n) ——

(a)

(b)

(c)

(d)

(e)

Explanation:

A server is a computer program or device that provides a service to another computer program and its user, also known as the client. In a data centre, the physical computer that a server program runs on is also frequently referred to as a server.


Q-13)   In latest generation computers, the instructions are executed

(a)

(b)

(c)

(d)

(e)

Explanation:

In the latest generation computers, the instructions are executed Both sequentially and in parallel.

In computer science, an instruction is a single operation of a processor defined by the processor instruction set. The size or length of an instruction varies widely, from as little as 4-bits in some microcontrollers to many as multiples of bytes in some very long instruction word (VLIW) systems.
