Computing & Printing

Computing

Platform or digital platform in the environment in which a piece of software is executed.

It may be the hardware or the operating system (OS), even a web browser and associated application programming interfaces, or other underlying software, as long as the program code is executed with it.

Printing

A printer is a device that accepts text and graphics output from a computer and transfers the information to paper, usually to standard size sheets of paper. 

Printers vary in size, speed, sophistication, and cost. In general, more expensive printers are used for higher-resolution color printing.
