FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -The hard drive is where your software, documents, and other files are stored. The hard drive is long-term storage, which means the data is still saved even if you turn the computer off or unplug it. When you run a program or open a file, the computer copies some of the data from the hard drive onto the RAM.

Detailed explanation-2: -Information technology (IT) is the use of computers to store, retrieve, transmit and manipulate data or information. IT is most commonly used in the context of business operations as opposed to personal or entertainment technology. IT is seen as a subset of information and communication technology (ICT).

Detailed explanation-3: -The term “VM sprawl” is used to describe a situation in which a large number of deployed virtual machines lack proper administrative controls.

Detailed explanation-4: -Alternatively referred to as main memory, primary memory, or system memory, Random Access Memory is a hardware device that allows information to be stored and retrieved on a computer. It is a volatile memory and requires power to keep the data accessible. If the computer is turned off, all data contained in it is lost.
