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.

What was the total number of UNIVAC-I sold eventually and by which company?

British Tabulating Machine Co. (BTM)

International Business Machines (IBM)

International Computer Ltd. (ICL)

Remington Rand

Correct Answer : Remington Rand

This was corrected by adding offline card processing equipment, the UNIVAC Tape to Card converter, to transfer data between cards and UNIVAC magnetic tapes. However, the early market share of the UNIVAC I was lower than the Remington Rand Company wished.

Remington Rand was an early American business machines manufacturer, best known originally as a typewriter manufacturer and in a later incarnation as the manufacturer of the UNIVAC line of mainframe computers. Formed in 1927 following a merger, Remington Rand was a diversified conglomerate making other office equipment, electric shavers, etc. The Remington Rand Building at 315 Park Avenue South in New York City is a 20-floor skyscraper completed in 1911. After 1955, Remington Rand had a long list of mergers and acquisitions that eventually resulted in the formation of Unisys.

In which year were chips used inside the computer for the first time?

1961

1969

1975

1987

Correct Answer : 1975

In 1975 chip was used inside the Personal computer for the very first time.

The first working microprocessor was built in 1975 by Micro Instrumentation and Telemetry Systems designed for the microcomputer Altair 8800 in Intel 8080 CPU. The computer chip or chip is an integrated circuit embedded or designed on a semiconductor material, these chips are used to process and store memory are a basic part of the working of a computer. The chip comprises of transistor, diodes, capacitor and resistor glued on a thin substrate of a semiconductor basically silicon ranging in few millimeters.

A single bus structure is primarily found in

Super computers

Main frames

Mini-and micro-computers

High performance machines

Correct Answer : 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).

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

Kurzweil Data Entry Machine (KDEM)

Optical character reader

Laser scanner

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?

Multi programming

Real time programming

Batch programming

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?

Control unit

Logic unit

Arithmetic unit

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.
