Teleprocessing is a term that was created in 1962 and refers to computer processing and the exchanging of data via remote terminals. The term was coined by IBM and is also referred to as remote control computing or, simply, remote computing.

Telecommunications is a word for all communications over a distance by cable, telephone, telegraph or broadcasting. Teleprocessing is computer service in which terminals are connected to a central computer.

No, the first known electronic spreadsheet was a WYSIWYG full screen mainframe system, known as "The Works Records System", programmed entirely in IBM Assembly language, using IBM 3270 terminals and the CICS teleprocessing System as the multi-tasking transaction processor. It was created in 1974 - six years before Visicalc and was still operational until 2001 (27 years) at ICI in Cheshire, UK. It was a fully networked system and was used by Chemical Engineers to calculate tank yields in the manufacturing facilities at Runcorn and elsewhere. No programming was involved for the engineers, they just entered "formula" linking the various "cells" together as in a typical spreadsheet. Cells could have up to 5 levels of naming. Backup and recovery was built-in and it was a sharable system from the outset. It automatically created "aged" data on a Shift, Day, Week, Month or Yearly basis and could handle data added later to re-calculate previous results. These facts were deleted from Wikipedia by overenthusiastic editors. There is an extant copy of the user manual, describing the System at "The Computer History museum" in CA, USA.

The prefix to "tele" is "tele-", which comes from the Greek word "tele" meaning "far off" or "distant." It is commonly used in words related to communication over a distance, such as telephone or television.
