Computer science is the study of processes that interact with data and that can be represented as data in the form of programs. It enables the use of algorithms to manipulate, store, and communicate digital information. A computer scientist studies the theory of computation and the design of software systems.
Q.Digital computers use a system to encode data and programs that is called:
⇒ A binary code represents text, computer processor instructions, or any other data using a two-symbol system. The two-symbol system used is often “0” and “1” from the binary number system. The binary code assigns a pattern of binary digits, also known as bits, to each character, instruction, etc
Q. PARAM a series of supercomputers was developed by:
⇒ 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 Brahma.
Q. Which type of memory holds only the program and data that the CPU is presently processing?
⇒ Random-access memory is a form of computer memory that can be read and changed in any order, typically used to store working data and machine code. A random-access memory device allows data items to be read or written in almost the same amount of time irrespective of the physical location of data inside the memory.
Q. Which of the following is the largest unit of storage?
⇒ The terabyte is a multiple of the unit byte for digital information. The prefix tera represents the fourth power of 1000, and means 10¹² in the International System of Units, and therefore one terabyte is one trillion bytes. The unit symbol for the terabyte is TB.
1 TB = 1000000000000bytes = 10¹²bytes = 1000gigabytes.
Q. Where is RAM located in computer?
Ans: Mother Board
⇒ RAM is located in The central processing unit (CPU), also called a processor, is located inside the computer case on the motherboard. It is sometimes called the brain of the computer, and its job is to carry out commands.
Q. A process of searching bugs in software is called:
⇒ Debugging is the process of finding and resolving defects or problems within a computer program that prevent correct operation of computer software or a system.Debugging tactics can involve interactive debugging, control flow analysis, unit testing, integration testing, log file analysis, monitoring at the application or system level, memory dumps, and profiling.
Q. Computer programs are written in a high level programming language, however the human readable version of a program is called:
Ans: Source code
⇒ Source code is the list of human-readable instructions that a programmer writes—often in a word processing program—when he is developing a program. The source code is run through a compiler to turn it into machine code, also called object code, that a computer can understand and execute.
Q. Most application software today comes with an interface called:
Ans: Graphical user interface
⇒ The graphical user interface is a form of user interface that allows users to interact with electronic devices through graphical icons and audio indicator such as primary notation, instead of text-based user interfaces, typed command labels or text navigation.
Q. A small group of computers and peripherals linked together in a small geographic area is called:
Ans: LAN ‘Local Area Network’
⇒ A local area network is a computer network that interconnects computers within a limited area such as a residence, school, laboratory, university campus or office building. By contrast, a wide area network not only covers a larger geographic distance, but also generally involves leased telecommunication circuits.
Q. Inventor of WWW ‘World Wide Web’ is:
Ans: Tim Berners Lee
⇒ Sir Timothy John Berners-Lee OM KBE FRS FREng FRSA FBCS, also known as TimBL, is an English engineer and computer scientist best known as the inventor of the World Wide Web. He is a Professorial Fellow of Computer Science at the University of Oxford and a professor at the Massachusetts Institute of Technology.
