MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -Short-term memory (or “primary” or “active memory") is the capacity for holding a small amount of information in an active, readily available state for a short interval. For example, short-term memory holds a phone number that has just been recited.

Detailed explanation-2: -Examples of short term memory include where you parked your car this morning, what you had for lunch yesterday, and remembering details from a book that you read a few days ago.

Detailed explanation-3: -RAM (random access memory) is a computer’s short-term memory, where the data that the processor is currently using is stored. Your computer can access RAM memory much faster than data on a hard disk, SSD, or other long-term storage device, which is why RAM capacity is critical for system performance.

Detailed explanation-4: -In computer terms, short-term memory is like the RAM – it holds the information we’re currently working with or using for cognitive tasks (thinking). This can be new information delivered by our senses, for example, or old information retrieved from the long-term memory.

Detailed explanation-5: -Because of its volatility, RAM can’t store permanent data. RAM can be compared to a person’s short-term memory, and a hard disk drive to a person’s long-term memory. Short-term memory is focused on immediate work, but it can only keep a limited number of facts in view at any one time.
