On November 8, 2019, the Congressional Gold Medal was awarded "In recognition of all the women who served as computers, mathematicians, and engineers at the National Advisory Committee for Aeronautics and the National Aeronautics and Space Administration (NASA) between the 1930s and the 1970s." [46] Computers for the Explorer 1 trajectory.
The history of the personal computer as a mass-market consumer electronic device began with the microcomputer revolution of the 1970s. A personal computer is one intended for interactive individual use, as opposed to a mainframe computer where the end user's requests are filtered through operating staff, or a time-sharing system in which one large processor is shared by many individuals.
Original floppy disk drives for the PC-8001 are the dual-unit PC-8031 and the additional dual-unit PC-8032, which use 143 KB single-sided 5.25-inch format. They were followed by the single-unit PC-8031-1V, the dual-sided PC-8031-2W and PC-8032-2W. These units are attached to the PC-8001 through the PC-8011 or the PC-8033 adapter.
A personal computer, often referred to as a PC or simply computer, is a computer designed for individual use. [1] It is typically used for tasks such as word processing, internet browsing, email, multimedia playback, and gaming. Personal computers are intended to be operated directly by an end user, rather than by a computer expert or technician.
PC-1 programs would work unmodified on the PC-3 and on the PC-8 with changes for screen size, and PC-4 (26-3650B) programs would run unmodified on the PC-5, PC-6 and PC-7. The PC-2 was a unique architecture and was the only unit in the line allowing direct memory access with POKE, PEEK and CALL.
Much of the research in this field seeks to improve the human–computer interaction by improving the usability of computer interfaces. [8] How usability is to be precisely understood, how it relates to other social and cultural values, and when it is, and when it may not be a desirable property of computer interfaces is increasingly debated.
The Xfce desktop environment offers a graphical user interface following the desktop metaphor.. In the industrial design field of human–computer interaction, a user interface (UI) is the space where interactions between humans and machines occur.
The integrated circuit is an essential invention to produce modern software systems. [2]The first use of the word software to describe computer programs is credited to mathematician John Wilder Tukey in 1958. [3]
