Random Access Memory (RAM) is the hardware in a computing device that provides temporary storage for the operating system (OS), software programs and any other data in current use so they're quickly available to the device's processor.

Random access memory is considered part of a computer's primary memory. It is much faster to read from and write to than secondary storage, such as hard disk drives (HDDs), solid-state drives (SSDs) or optical drives.

However, RAM is volatile; it retains data only as long as the computer is on. If power is lost, so is the data. When the computer is rebooted, the OS and other files must be reloaded into RAM, usually from an HDD or SSD. Hence, statement of option (b) is not true about RAM.

Solid State Drive, Hard Disk and USB Pen Drive are types of computer's external or secondary memory while Random Access Memory (RAM) is part of computer's internal or primary memory.

Cache memory is an extremely fast, small memory between CPU and main memory. It stores data from a computer or program that is often used by the CPU.

Cache memory, also called as CPU memory, is random-access memory (RAM) that a computer microprocessor can access more quickly than it can access regular RAM. The Cache has the shortest access time or latency of all the levels of the storage system and the highest bandwidth.

'Flash memory' which is used in computers and other digital bodies or devices is a type of memory that persists even when the power is off. Pen drive, digital camera, and memory card are the examples of flash memory.

In comparison to the hard drive, a flash memory is much energy efficient. But if we compare in the terms of per unit storage of flash drive, it is expensive than normal hard drive.

COBOL stands for Common Business Oriented Language. It is a computer language developed for professional interest.

Oracle is a database software, produced and marketed by Oracle Corporation. Database management system is computer software application that interacts with the user, other applications and the database itself to capture and analyze data.

BASIC is a computer language. It is an acronym for 'Beginner's All Purpose Symbolic Instruction Code'. FORTRAN is acronym for 'Formula Translation'. It is a high level computer language. C is also a computer language. FAST is not a computer language.
