General Knowledge(GK) (or) General Awareness

Welcome to the General Knowledge Section of Free Time Learning. As we are aware General Knowledge (GK) is a very important area in all the competitive exams held in the country. Nowadays, a good knowledge of general awareness is very important in clearing any competitive and government recruitment examinations.

These General Knowledge Question are very important and usefull to UPSC, IAS/PCS, UPPSC, IBPS, SBI, RBI, SSC, CGL, Railway, APPSC, TSPSC, KPSC, TNPSC, TPSC, UPPSC, MPSC, RPSC, BPSC, MPPSC, UKPSC, MPSC, and other competitive exams.

Mini-and micro-computers
D)
High performance machines

Correct Answer : Option (C) - Mini-and micro-computers


A single bus structure is primarily found in Mini- and micro computers.
 
A microcomputer is a small, relatively inexpensive computer with a microprocessor as its central processing unit (CPU).[2] It includes a microprocessor, memory, and minimal input/output (I/O) circuitry mounted on a single printed circuit board.[3] Microcomputers became popular in the 1970s and 1980s with the advent of increasingly powerful microprocessors. The predecessors to these computers, mainframes and minicomputers, were comparatively much larger and more expensive (though indeed present-day mainframes such as the IBM System z machines use one or more custom microprocessors as their CPUs).
 
Minicomputers (midrange computers) Minicomputers (colloquially, minis) are a class of multi-user computers that lie in the middle range of the computing spectrum, in between the smallest mainframe computers and the largest single-user systems (microcomputers or personal computers).

Kurzweil Data Entry Machine (KDEM)
B)
Optical character reader
C)
Laser scanner
D)
MICR

Correct Answer : Option (A) - Kurzweil Data Entry Machine (KDEM)


Kurzweil Data Entry Machine (KDEM) as an input device for literary and linguistic computing It is based on over five years' experience of providing an optical reading service for academic users The KDEM is an ‘intelligent’ optical character reader in that it is able to ‘learn’ the shapes of the letters in a text It can read proportionately spaced (typeset) text as well as uniformly spaced material (typescript) and can recognise different fonts as well as superscripts, subscripts and underlining Any script in which the letters do not join can be read The accuracy and speed of the reading depend very much on how well the KDEM has been trained Speeds of up to 30 pages per hour can be obtained on a good text with the aid of a built-in lexicon of about 33,000 English words The most suitable types of text are solid blocks or pages in a single typeface which have been printed on relatively smooth paper Dictionaries and bibliographies can be read but are more difficult because of frequent changes of typeface Newspapers and computer printout are unsuitable...

A)
Multi programming
B)
Real time programming
C)
Batch programming
D)
None of the above

Correct Answer : Option (B) - Real time programming


Real time programming type of computer programming is used for airplane ticket reservation system.
 
A real-time system is one where it has to respond within certain time limits, for example, the avionics of a plane, or the control system of an industrial process.
 
If the system does not respond in a timely manner, it's potentially dangerous.If an online railway reservation system is slow to respond, that's annoying; if a system controlling a train is slow to respond, that's bad.
 
In computer science, real-time computing (RTC), or reactive computing describes hardware and software systems subject to a "real-time constraint", for example from event to system response. Real-time programs must guarantee response within specified time constraints, often referred to as "deadlines".

B)
Logic unit
C)
Arithmetic unit
D)
Register

Correct Answer : Option (A) - Control unit


The control unit (CU) is a component of a computer's central processing unit (CPU) that directs the operation of the processor. It tells the computer's memory, arithmetic/logic unit and input and output devices how to respond to the instructions that have been sent to the processor.
