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 one-bit signal that indicates the start of data transmission by an asynchronous device is
A)
Start bit
B)
Parity bit
C)
Status bit
D)
Zero bit

Correct Answer :   Start bit

A one-bit signal that indicates the start of data transmission by an asynchronous device is Start bit
 
Parallel devices have a wider data bus than serial devices and can therefore transfer data in words of one or more bytes at a time. As a result, there is a speedup in parallel transmission bit rate over serial transmission bit rate.
 
In telecommunication and data transmission, serial communication is the process of sending data one bit at a time, sequentially, over a communication channel or computer bus. This is in contrast to parallel communication, where several bits are sent as a whole, on a link with several parallel channels.
 
Data transmission refers to the process of transferring data between two or more digital devices. Data is transmitted from one device to another in analog or digital format. Basically, data transmission enables devices or components within devices to speak to each other.

Who is 1988 announced the latest version of CD-ROM called CD-ROMXA (extended architecture) which provides a documented means of integrating digital audio with computer data on a CD-ROM disk?
A)
Sony
B)
Philips
C)
Microsoft
D)
All of the above

Correct Answer :   All of the above

A CD-ROM is a pre-pressed optical compact disc which contains data. The name is an acronym which is short for "Compact Disc Read-Only Memory". Computers can read CD-ROMs, but cannot write to CD-ROMs, which are not writable or erasable.
 
Several formats are used for data stored on compact discs, known as the Rainbow Books. The Yellow Book, published in 1988, defines the specifications for CD-ROMs, standardized in 1989 as the ISO/IEC 10149 / ECMA-130 standard. The CD-ROM standard builds on top of the original Red Book CD-DA standard for CD audio. Other standards, such as the White Book for Video CDs, further define formats based on the CD-ROM specifications. The Yellow Book itself is not freely available, but the standards with the corresponding content can be downloaded for free from ISO or ECMA.

Which of the following is the expansion of EBCDIC
A)
Extended binary coded decimal information code
B)
Extended bootable computerised digital infrared calculator
C)
Extended binary coded decimal interchange code
D)
Extended bit comparable to digital interface for computer

Correct Answer :   Extended binary coded decimal interchange code

Extended Binary Coded Decimal Interchange Code (EBCDIC) is an 8-bit binary code for numeric and alphanumeric characters. It was developed and used by IBM. It is a coding representation in which symbols, letters and numbers are presented in binary language.
 
Extended Binary Coded Decimal Interchange Code is an eight-bit character encoding used mainly on IBM mainframe and IBM midrange computer operating systems. It descended from the code used with punched cards and the corresponding six bit binary-coded decimal code used with most of IBM's computer peripherals of the late 1950s and early 1960s. It is supported by various non-IBM platforms, such as Fujitsu-Siemens' BS2000/OSD, OS-IV, MSP, and MSP-EX, the SDS Sigma series, Unisys VS/9, Burroughs MCP and ICL VME.

Computer can not do anything without a
A)
Memory
B)
Program
C)
Chip
D)
Output device

Correct Answer :   Program

A computer program is a collection of instructions that performs a specific task when executed by a computer. Most computer devices require programs to function properly.
A computer program is usually written by a computer programmer in a programming language. From the program in its human-readable form of source code, a compiler or assembler can derive machine code—a form consisting of instructions that the computer can directly execute.

The most popular language used with microcomputers and time-shared mini computers, is an easy-to-use high level language.
A)
ADA
B)
BASIC
C)
COBOL
D)
PASCAL

Correct Answer :   BASIC

BASIC is a family of general-purpose, high-level programming languages whose design philosophy emphasizes ease of use. In 1964, John G. Kemeny and Thomas E. Kurtz designed the original BASIC language at Dartmouth College. They wanted to enable students in fields other than science and mathematics to use computers.
