Correct Answer :   More than one process

Multitasking, in an operating system, is allowing a user to perform more than one computer task (such as the operation of an application program) at a time. The operating system is able to keep track of where you are in these tasks and go from one to the other without losing information.

Correct Answer :   Array

Correct Answer :   RAM

RAM is normally associated with volatile types of memory (such as DRAM modules), where stored information is lost if power is removed

Correct Answer :   J presper Eckert and John W Mauchly

ENIAC was designed by John Mauchly and J. Presper Eckert of the University of Pennsylvania, U.S. The team of design engineers assisting the development included Robert F. Shaw (function tables), Jeffrey Chuan Chu (divider/square-rooter), Thomas Kite Sharpless (master programmer), Frank Mural (master programmer), Arthur Burks (multiplier), Harry Huskey (reader/printer) and Jack Davis (accumulators). Significant development work was undertaken by the ENIAC women programmers: Jean Jennings, Marlyn Wescoff, Ruth Lichterman, Betty Snyder, Frances Bilas, and Kay McNulty. In 1946, the researchers resigned from the University of Pennsylvania and formed the Eckert–Mauchly Computer Corporation.

Correct Answer :   transfer information both to and from a hard drive

Correct Answer :   A numerical network label

An Internet Protocol address (IP address) is a numerical label assigned to each device connected to a computer network that uses the Internet Protocol for communication. An IP address serves two main functions: host or network interface identification and location addressing.

Correct Answer :   A modem

Digital-to-analog conversion (DAC), Process by which digital signals (which have a binary state) are converted to analog signals (which theoretically have an infinite number of states). For example, a modem converts computer digital data to analog audio-frequency signals that can be transmitted over telephone lines.

Correct Answer :   Magnetic disk

Correct Answer :   ROM

Examples of non-volatile memory include read-only memory (see ROM), flash memory, most types of magnetic computer storage devices (e.g. hard disks, floppy discs and magnetic tape), optical discs, and early computer storage methods such as paper tape and punched cards.

Correct Answer :   Super computer

Super computers were introduced in the 1960s as the world's most advanced computer. A supercomputer is a powerful computer that can process a large amount of data and computation very quickly.
