FORTRAN is a programming language developed by IBM in the 1950s. The name comes from 'Formula Translation' because it was designed for scientific and engineering calculations involving mathematical formulas. 'File Translation' and 'Format Translation' are incorrect expansions.

EEPROM stands for Electrically Erasable Programmable Read Only Memory. It is a type of non-volatile memory that can be electrically erased and reprogrammed. Unlike 'Easily' or 'Electronic', the correct expansion emphasizes the electrical erasure mechanism.

Second Generation computers (1956-1965) used transistors instead of vacuum tubes. First Generation was 1949-1955, Third Generation was 1965-1970 (integrated circuits), and Fourth Generation was 1970 onwards (microprocessors).

First Generation computers (1949-1955) were enormous, often room-sized, because they used vacuum tubes which were bulky and generated significant heat. Each successive generation became progressively smaller with advances in transistor and integrated circuit technology.

The fourth generation of computers (1971-present) is characterized by the use of microprocessors, which integrated thousands of integrated circuits onto a single silicon chip.

UNIVAC (Universal Automatic Computer) was one of the first commercially produced computers, introduced in 1951. It was used primarily for business and data processing applications. 'Array' and 'Unique' are incorrect expansions.

CD-ROM stands for Compact Disk Read Only Memory. It is a pre-pressed optical compact disc that contains data which can be read but not written to. The correct expansion uses 'Disk' not 'Disk', and 'Read Only Memory' not 'Read Only Memory' alone.

ALU (Arithmetic Logic Unit) is a digital circuit that performs arithmetic and logical operations. It is a fundamental component of a computer's CPU. 'Array' and 'Application' are incorrect expansions.

VGA (Video Graphics Array) is a display standard introduced by IBM in 1987. It became widely adopted for computer monitors and graphics cards. 'Visual' and 'Volatile' are incorrect expansions.

IBM 1401 was introduced in 1959 and used transistor technology, placing it in the Second Generation of computers (1956-1965). First Generation used vacuum tubes, Third Generation used integrated circuits, and Fourth Generation used microprocessors.
