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.

The data bus in 8080A/8085 microprocessor is a group of
A)
eight unidirectional lines that are used for I/O devices
B)
eight lines used to transfer data among the registers
C)
sixteen bidirectional lines that are used for data transfer between the microprocessor and memory
D)
eight bidirectional lines that are used to transfer 8 bits between the microprocessor and its I/O and memory

Correct Answer :   eight bidirectional lines that are used to transfer 8 bits between the microprocessor and its I/O and memory

The data bus in 8080A/8085 microprocessor is a group of eight bidirectional lines that are used to transfer 8 bits between the microprocessor and its I/O and memory.
 
Diagram to represent bus organization system of 8085 Microprocessor. It is a group of conducting wires which carries address only.Address bus is unidirectional because data flow in one direction, from microprocessor to memory or from microprocessor to Input/output devices
 
It is unidirectional.In Intel 8085 microprocessor, Address bus was of 16 bits. This means that Microprocessor 8085 can transfer maximum 16 bit address which means it can address 65,536 different memory locations. This bus is multiplexed with 8 bit data bus.
 
An address bus is a computer bus architecture used to transfer data between devices that are identified by the hardware address of the physical memory (the physical address), which is stored in the form of binary numbers to enable the data bus to access memory storage.

A new technology which provides the ability to create an artificial world and have people interact with it is called
A)
alternative reality
B)
3-D reality
C)
virtual reality
D)
televirtuality

Correct Answer :   virtual reality

A new technology which provides the ability to create an artificial world and have people interact with it is called virtual reality.
 
an artificial environment which is experienced through sensory stimuli (such as sights and sounds) provided by a computer and in which one's actions partially determine what happens in the environment; also : the technology used to create or access a virtual reality.
 
Virtual reality is an artificial environment that is created with software and presented to the user in such a way that the user suspends belief and accepts it as a real environment. On a computer, virtual reality is primarily experienced through two of the five senses: sight and sound.

Which of the following are not likely to be found on a PC main circuit board
A)
RAM chips
B)
ROM chips
C)
Microprocessor chips
D)
LCD clocks

Correct Answer :   LCD clocks

LCD clocks are not likely to be found on a PC main circuit board.
 
The CPU requires a fixed number of clock ticks (or clock cycles) to execute each instruction. The faster the clock, the more instructions the CPU can execute per second. Clock speeds are expressed in megahertz (MHz) or gigahertz ((GHz).
 
Therefore, clock is used to bring some regularity to the system. So, a clock signal is a particular type of signal that oscillates between a high and a low state and it is used to coordinate actions of digital circuits. A clock signal is produced by a clock generator.

Which company produces processors for the Apple Macintosh?
A)
Intel
B)
IBM
C)
Motorola
D)
AMD

Correct Answer :   Motorola

Motorola company produces processors for the Apple Macintosh.
 
The Macintosh (pronounced as /ˈmækɪnËŒtɒʃ/ MAK-in-tosh; branded as Mac since 1998) is a family of personal computers designed, manufactured, and sold by Apple Inc. since January 1984. The original Macintosh was the first mass-market personal computer that featured a graphical user interface, built-in screen and mouse.
 
Macintosh systems still found success in education and desktop publishing and kept Apple as the second-largest PC manufacturer for the next decade. In the early 1990s, Apple introduced models such as the Macintosh LC II and Color Classic which were price-competitive with Wintel machines at the time. However, the introduction of Windows 3.1 and Intel's Pentium processor which beat the Motorola 68040 in most benchmarks gradually took market share from Apple, and by the end of 1994 Apple was relegated to third place as Compaq became the top PC manufacturer. Even after the transition to the superior PowerPC-based Power Macintosh line in the mid-1990s, the falling prices of commodity PC components, poor inventory management with the Macintosh Performa, and the release of Windows 95 saw the Macintosh user base decline.
