Computer hardware is the physical parts of a computer, as distinguished from the computer software or computer programs and data that operate within the hardware. The hardware of a computer is infrequently changed, in comparison with software and data which are "soft" in the sense that they are readily created, modified or erased on the computer. Firmware is special software that rarely, if ever, needs to be changed and so is stored on hardware devices such as read-only memory (ROM) where it is not readily ch ...

A password is a form of secret authentication data that is used to control access to a resource. The password is kept secret from those not allowed access, and those wishing to gain access are tested on whether or not they know the password and are granted or denied access accordingly. The use of passwords goes back to ancient times. Sentries guarding a location would challenge for a password. They would only allow a person in if they knew the password. In modern times, passwords are used to control access to protected computer ...

PIP was originally named ATLATL, which was an acronym for "Anything Lord to Anything Lord". This described its purpose as a device independent file copying tool. After some use, it was finally realized that the hand-crafted syntax: PIP destination=source actually was inverted from common English usage. Thus the command: COPY source destination syntax was born, one of the dozens of utilities that resided on the PDP and DEC machines. As late as the m ...

The original "Platinum" Power Macintosh G3 series (commonly called "beige G3s") came in three versions: a desktop enclosure inherited directly from the Power Mac 7300; a minitower similar to (but shorter than) the Power Mac 8600 enclosure; and a version with a built in screen, the G3 All-In-One (AIO), that was made available only to educational markets. Equipped with a 233, 266, 300, or 333 MHz PowerPC G3 CPU from Motorola, these machines used a 66 MHz system bus and PC66 SDRAM (actual operating frequencies 66.83 MHz), and used standard ATA hard disk drives instead of the SCSI ...
