Question Discussion & Solution

Explanation:

• The purpose of regression testing is to confirm that a recent program or code change has not adversely affected existing features.
• Regression testing is nothing but a full or partial selection of already executed test cases that are re-executed to ensure existing functionalities work fine.
• This testing is done to make sure that new code changes should not have side effects on the existing functionalities. It ensures that the old code still works once the new code changes are done.

The purpose of regression testing is to select test cases partially or fully to ensure existing functionalities work fine. Thus, regression testing is primarily related to functional testing

Need of Regression Testing

• Regression Testing is required when there is a change in requirements and code is modified according to the requirement or when one of the following has been done.
  • New feature is added to the software
  • Defect fixing
  • Performance issue fix

The correct answer is Sirohi.

Key Points

• In Battle of Kayadara 1178, fought between Muhammad of Ghori and Bhimdev II the battle took place at Kayadra near Mount Abu (Sirohi District).

Important Points

• The battle of Kayadara (1178):
  • Gujarat was ruled by Mularaja II (1175-78: Chalukyan Dynasty) he was young at the time of Coronation.
  • In 1178, Mohd. Ghori crossed the desert and marched towards Gujarat.
  • Naikidevi (Mother of Mularaja) met forces of Ghori at Kayadara (near Mount Abu).
  • Naikidevi inflicted a major defeat to Muhammad Ghori and he was forced to retreat.
  • In 1178 itself, Bhima II, brother of Mularaja II succeeded Mularaja II.
  • As both the brothers occupied the throne during 1178, hence some historians also credit Bhima II with defeating Mohd. Ghori.

​The correct answer is Truck farming.

Key Points

• The farmers specialize in vegetables only, this type of farming is known as Truck farming.
• In the regions where farmers specialize in vegetables only, the farming is known as Truck farming, and the distance of truck farms from the market is governed by the distance that a truck can cover overnight, hence the name truck farming.
• Vegetable farms are in some regions known as truck farms: "truck" is a noun for which its more common meaning overshadows its historically separate use as a term for "vegetables are grown for the market".
• The production of crops of some vegetables on an extensive scale in regions especially suited to their culture primarily for shipment to distant markets known as Truck farming.
• The major truck-farming areas are in California, Texas, Florida, along the Atlantic Coastal Plain, and in the Great Lakes area.
• Centres for specific crops vary with the season. Among the most important truck crops are tomatoes, lettuce, melons, beets, broccoli, celery, radishes, onions, cabbage, and strawberries.

Additional Information

The correct answer is SRAM.

​Key Points

• SRAM memory devices are very much similar, mainly in terms of speed, to the cache memory.
• SRAM stands for Static random-access memory.
• Static random-access memory is a type of random-access memory that uses latching circuitry to store each bit.
• SRAM is volatile memory; data is lost when power is removed.
• The term static differentiates SRAM from DRAM which must be periodically refreshed.

Additional Information

• Dynamic random access memory (DRAM) is a type of semiconductor memory that is typically used for the data or program code needed by a computer processor to function.
• Flash memory, also known as flash storage, is a type of nonvolatile memory that erases data in units called blocks and rewrites data at the byte level.
• EEPROM (electrically erasable programmable read-only memory) is user-modifiable read-only memory (ROM) that can be erased and reprogrammed (written to) repeatedly through the application of higher than normal electrical voltage.

The study of individual organisms and their interaction with the environment is known as autecology.

Key Points 

• Ecology is the study of the interaction of organisms with their environment.
• Synecology and autecology is the branch of ecology.
• Synecology is the study of a group of organisms and their relation to the environment.
• Community ecology or synecology is the study of the interactions between species in communities on many spatial and temporal scales, including the distribution, structure, abundance, demography, and interactions between coexisting populations.
• For example, the study of the entire grassland ecosystem.
