Each byte is able to represent 256 different numbers (28 = 256); either from 0 to 255 or âˆ’128 to +127. The Mark 1 produced mathematical tables but was soon superseded by electronic stored-program computers.
It was also one of the first computers to use all-diode logic, a technology more reliable than vacuum tubes. All of the arithmetic-related instructions were passed on to its arithmetic unit and further decoded there.) Control systems in advanced computers may change the order of some instructions so as to improve performance.
Although programmers typically need to rewrite their programs to work on different system platforms, such as Windows or OS X, applications created with SaaS work on all platforms. Viruses can be spread through interchange of files and programs, loaded onto a computer and executed.
