Q2. Which language understand the computer?

Ans.

Computers understand machine language, which is a set of binary codes representing instructions that the computer can execute.

Q6. What is Ram? What is Rom?

Ans.

RAM stands for Random Access Memory, a type of computer memory that can be accessed randomly. ROM stands for Read-Only Memory, a type of memory that stores data permanently.

  • RAM is volatile memory used by the computer to store data and program instructions temporarily.

  • ROM is non-volatile memory that stores firmware and cannot be easily modified or deleted.

  • RAM is faster but loses data when power is turned off, while ROM is slower but retains data even when power is off.

Q7. what is indexing

Ans.

Indexing is a technique used to optimize the performance of databases by creating a data structure that allows for quick retrieval of data.

  • Indexing involves creating a data structure that maps the values of a particular column in a database table to their physical storage locations on disk.

  • It helps in speeding up data retrieval operations by allowing the database to quickly locate the rows that satisfy a certain condition without having to scan the entire table.

  • Examples of in...read more
