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 is the number of bits needed for an address in a 4 K memory?
A)
4
B)
8
C)
12
D)
16

Correct Answer : Option (C) - 12

12 bits needed for an address in a 4K memory
 
Likewise, you need 20 bits to address every byte in a megabyte, and 30 bits to address every byte in a gigabyte. 232 = 4294967296, which is the number of bytes in 4 gigabytes, so you need a 32 bit address for 4 GB of memory.
 
As I mentioned before, it's the size of a machine word. Machine word is the amount of memory CPU uses to hold numbers (in RAM, cache or internal registers). 32-bit CPU uses 32 bits (4 bytes) to hold numbers. Memory addresses are numbers too, so on a 32-bit CPU the memory address consists of 32 bits.

A storage area used to store data to compensate for the difference in speed at which the different units can handle data is
A)
Memory
B)
Buffer
C)
Address
D)
Accumulator

Correct Answer : Option (B) - Buffer

A buffer, also called buffer memory, is a portion of a computer's memory that is set aside as a temporary holding place for data that is being sent to or received from an external device, such as a hard disk drive (HDD), keyboard or printer.

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 : Option (D) - 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 : Option (C) - 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.
