Correct Answer : Electronic spread sheet

A software package to perform calculations on data arranged in an array is Electronic spread sheet.

A spreadsheet is an interactive computer application for organization, analysis and storage of data in tabular form. Spreadsheets are developed as computerized simulations of paper accounting worksheets.[4] The program operates on data entered in cells of a table. Each cell may contain either numeric or text data, or the results of formulas that automatically calculate and display a value based on the contents of other cells. A spreadsheet may also refer to one such electronic document.

B)

International Business Machines (IBM)

C)

International Computer Ltd. (ICL)

D)

Remington Rand

Correct Answer : Remington Rand

This was corrected by adding offline card processing equipment, the UNIVAC Tape to Card converter, to transfer data between cards and UNIVAC magnetic tapes. However, the early market share of the UNIVAC I was lower than the Remington Rand Company wished.

Remington Rand was an early American business machines manufacturer, best known originally as a typewriter manufacturer and in a later incarnation as the manufacturer of the UNIVAC line of mainframe computers. Formed in 1927 following a merger, Remington Rand was a diversified conglomerate making other office equipment, electric shavers, etc. The Remington Rand Building at 315 Park Avenue South in New York City is a 20-floor skyscraper completed in 1911.
