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.

A printed document reader which scans the characters and then encodes them in a computer-compatible code for direct transmission to the computer is called
A)
Kurzweil Data Entry Machine (KDEM)
B)
Optical character reader
C)
Laser scanner
D)
MICR

Correct Answer :   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...

What type of computer programming is used for airplane ticket reservation system?
A)
Multi programming
B)
Real time programming
C)
Batch programming
D)
None of the above

Correct Answer :   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".

Who coordinates the sequencing of events within the central processor of a computer?
A)
Control unit
B)
Logic unit
C)
Arithmetic unit
D)
Register

Correct Answer :   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.

A)
Laser printer
B)
Band printer
C)
Golf ball printer
D)
Dot-matrix printer

Correct Answer :   Band printer

A code which uses more bits for each character then what is necessary is known as
A)
Gray code
B)
Mnemonics
C)
Hollerith code
D)
Redundant code

Correct Answer :   Redundant code

A code which uses more bits for each character then what is necessary is known as Redundant code.
 
In computer programming, redundant code is source code or compiled code in a computer program that is unnecessary, such as: recomputing a value that has previously been calculated and is still available, code that is never executed (known as unreachable code), code which is executed but has no external effect. A NOP instruction might be considered to be redundant code that has been explicitly inserted to pad out the instruction stream or introduce a time delay.
 
An error-correcting code (ECC) or forward error correction (FEC) code is a process of adding redundant data, or parity data, to a message, such that it can be recovered by a receiver even when a number of errors (up to the capability of the code being used) were introduced, either during the process of transmission,etc,..

B)
Konard Zuse
C)
Howard H. Aliken
D)
Claude Shannon

Correct Answer :   George Stibits

In November 1937, George Stibitz, then working at Bell Labs (1930-1941), completed a relay-based calculator he later dubbed the "Model K" (for "kitchen table", on which he had assembled it), which calculated using binary addition.
