Led a number of civil disobedience campaigns, spending a number of spells in prison. Made numerous attempts between 1944-1947 to stop the partition of India but failed. Assassinated, 1948.
• Jawaharlal (Pandit) Nehru(1889-1964) Barrister and politician in the United Provinces of India; supporter of Gandhi; President of Indian National Congress, 1929, 1936-37, 1946, 1951-54; first prime minister of India, 1947-1964.

Concept:

A functional dependency is a constraint between two sets of attributes from the database.

Explanation:

In general form, a functional dependency denoted by X -> Y between two sets of attributes X and Y that are subsets of R specifies a constraint on the possible tuples that can form a relation state r of R.

The constraint is that for any two tuples T₁ and T₂ in r that have T₁[X] = T₂[Y], they must also have T₁[Y]

= T₂[Y]. It means that values of Y component of a tuple in r depend on or are determined by the value of X component.

If a relation R contains attributes (X and Y). Then X -> Y is a functional dependency. It means X functionally determines Y in R if and only if two tuples agree on their X value, they must necessarily agree on their Y value.

The correct answer is EEPROM.

Key Points

• Flash memory is a non-volatile computer storage chip,
• It is made up of EEPROM.
• EEPROM is the acronym of electrically erasable programmable read-only memory,
• EEPROM is a Programmable ROM that can be erased and reprogrammed using an electrical charge.
• It was first was developed by George Perlegos.
• It allows the user to update the computer BIOS without having to open the computer or remove any chips.
• It organized as arrays of floating-gate transistors.
• USB flash drive, Memory cards are the examples of flash memory storage.
• BIOS is stored in Flash memory chip.

Additional Information

• RDRAM is the acronym of Rambus Dynamic Random Access Memory.
  • It is a video RAM.
• MROM is the acronym of Mask ROM.
  • It is produced by arranging transistors before the semiconductor manufacturing process actually begins.
• SRAM is the acronym of Static random-access memory
  • It uses latching circuitry (flip-flop) to store each bit.
• PROM is the acronym of Programmable Read-Only Memory.
  • It can be modified only once by a user.

The correct answer is Constellation.

• Ursa Major constellation lies in the northern sky. Its name means “the great bear,” or “the larger bear” in Latin.
• Ursa Major is the largest northern constellation and third largest constellation in the sky.
  • Its brightest stars form the Big Dipper asterism, one of the most recognizable shapes in the sky, also known as the Plough.
• Ursa Major contains seven Messier objects. It also contains 13 stars with confirmed planets.

Important Points

• The biggest known galaxy is IC 1101, which is 50 times the Milky Way's size and about 2,000 times more massive.
  • It is about 5.5 million light-years across.
• Our Sun (a star) and all the planets around it are part of a galaxy known as the Milky Way Galaxy.
  • A galaxy is a large group of stars, gas, and dust bound together by gravity. The Milky Way is made up of about 90% dark matter, the matter which cannot be seen, and about 10% “luminous matter”, or matter that we can see with our eyes.
  • The solar system lies about 30,000 light-years from the galactic centre.

Additional Information

• Sirius, also known as the Dog Star or Sirius A, is the brightest star in Earth's night sky.
• The name means "glowing" in Greek.

The correct answer is Resolution.

• The number of horizontal and vertical pixels on a display screen is called Resolution.

​Key Points

• Resolution
  • ​ The number of horizontal and vertical pixels on a display screen is called Resolution.
  • The more pixels, the more information is visible without scrolling.
  • Screen resolutions have a pixel count such as 1600x1200, which means 1,600 horizontal pixels and 1,200 vertical pixels.
  • Screen resolutions also have base names, such as HDTV and Ultra UHD for TVs and XGA and WQXGA for computer monitors.  

Additional Information

• Dot Pitch 
  • ​Dot pitch is a measurement that defines the sharpness of a display.
  • It measures the distance between the dots used to display the image on the screen.
  • This distance is very small and is typically measured in fractions of millimetres.
• Aspect Ratio
  • ​Aspect ratio describes the ratio between the width and height of an image or screen.
  • The first number refers to the width, and the second number refers to the height.
  • A 1:1 aspect ratio, for example, is a square.
