Supercomputers are primarily used by universities, military and scientific research labs. They are used in high calculation-intensive jobs like quantum physics, weather and climate research, study of chemical compounds, simulation of aircraft in wind tunnels and detonation of nuclear weapons.

PARAM 8000 is considered India’s first supercomputer. It was built by the Centre for Development of Advanced Computing (C-DAC) with Russian collaboration.

Supercomputers was first introduced in the 1960s and designed primarily by Seymour Cray at the Control Data Corp (CDC).

210 Byte is equal to?

A)

1 MB


B)

1 KB


C)

1 GB


D)

1 TB



Correct Answer :

1 KB


Explanation :

In the binary system (using base 2)
1 byte = 8 bits
1 kilobyte (K / KB) = 210 bytes = 1,024 bytes
1 megabyte (M / MB) = 220 bytes = 1,048,576 bytes
1 gigabyte (G / GB) = 230 bytes = 1,073,741,824 bytes
1 terabyte (T / TB) = 240 bytes = 1,099,511,627,776 bytes
1 petabyte (P / PB) = 250 bytes = 1,125,899,906,842,624 bytes
1 exabyte (E / EB) = 260 bytes = 1,152,921,504,606,846,976 bytes

Which of the following is a first Generation Computer Language?

A)

Assembly language


B)

Machine language


C)

High level language


D)

None of these



Correct Answer :

Machine language


Explanation :

The languages used to give instructions to computers are called programming language. There are 4 different generations of programming languages are available.

First Generation Language (1GL)
The first generations of programming languages are also known as machine language or low-level language.
In the first generation language, the instructions are written in the form of binary i.e. 0 and 1 which is very difficult to understand. The first generation programming language doesn’t require any translator or converter to run the codes by machine. The codes are very fast and efficient but is tedious to write and is brittle to changes.The code can not ported to other systems and needs to be rewritten.

Second Generation Languages ​​(2GL)
It is also known as the assembly language. in the second generation language ,the instructions are written in the form of mnemonics codes to simplify the program. To execute these instructions, all mnemonics are converted into machine language with the help of a translator known as the assembler.
The program written using mnemonics is called source program .It is easier to read and write as compared to machine code.
2GL source code is not portable across processors or processing environments.The code cannot be ported to other system and it needs to be rewritten.

Third generation languages ​​(3GL)
The third generation programming languages are also known as high-level languages. In the third generations of programming languages, English language with symbols and digits are used to write programs. In order to execute the instructions or programs written in third generation language, the source program is to be translated into the machine language that done by the compiler or interpreter.
Basic, Fortran, Cobol, C, C ++, Java, Python are examples of of third generation programming languages.
High-level programs ​​can be platform independent, which means code written for one system will work on the other.

Fourth generation languages ​​(4GL)
The fourth generations of programming languages are languages that contain statements similar to a human language. Fourth-generation languages are designed to help reduce the programming effort for software development.

This languages ​​are designed keeping in mind a specific purpose, which are mostly written in high-level languages ​​such as C, C ++, JAVA, Python.
In which a user can perform a task without writing any programs and only need to enter the command that calls the specific program available in the package.

Queries (SQL), CSS, reports (Oracle Reports), User Interface (XUL), MS Word, PageMaker, AutoCAD etc are some of the most commonly used fourth-generation packages.
