In the following passage, some words have been deleted. Read the passage carefully and select the most appropriate option to fill in each blank.

Astronomers have discovered 62 new moons orbiting the ringed planet Saturn. Though some of the moons had been (1)________ as early as 2019, it takes more than sighting an object close to a planet to (2) ________ it is a moon and not an asteroid making a brief close passage to that planet.

Performing a painstaking (3) ________ of matching objects detected on different nights over the course of 24 months, the team tracked 63 objects that they ended up confirming as moons. One of (4) ________ satellites was revealed back in 2021, with the remaining 62 moons gradually announced over the past few weeks.

Which of the following is the correct categorisation of volatile semiconductor memory based on the data retention capability?

Show answer & explanation

Correct answer: B

Explanation

The correct answer is option 2 i.e. SRAM and DRAM 

  • The correct categorization of volatile semiconductor memory based on data retention capability includes:
  • SRAM (Static Random-Access Memory): SRAM is a type of volatile semiconductor memory known for its high-speed performance and the ability to retain data as long as power is supplied. It does not require constant refreshing, making it suitable for cache memory in computer systems.
  • DRAM (Dynamic Random-Access Memory): DRAM is another type of volatile semiconductor memory. It is widely used in computer systems for main memory (RAM). Unlike SRAM, DRAM requires periodic refreshing to maintain data integrity since it stores data as electrical charges in capacitors, which tend to leak over time.
  • SDRAM (Synchronous Dynamic Random-Access Memory): SDRAM is a variation of DRAM that synchronizes its operations with the computer's clock speed for improved performance. It shares the data retention characteristics of traditional DRAM and needs refreshing.
  • EEPROM (Electrically Erasable Programmable Read-Only Memory): EEPROM is a non-volatile memory type. It is not categorized as a volatile semiconductor memory because it can retain data even when power is removed. EEPROM is often used for storing configuration data or firmware in devices like microcontrollers
