Windows Operating System Interactions with BIOS and Real Time Clock
13. Glossary

Application: A program designed to perform a specific function for the user or for another application program. For example, word processing applications and database programs. Applications use the services of the computer's operating system and other supporting programs.

API: Application program interface. A method used to communicate a request to a computer operating system or another application.

BIOS: Basic input/output system. The BIOS firmware in a personal computer (PC) interfaces directly with the hardware to perform input/output and other low-level functions.

Boot process: The first part of the BIOS firmware program. It starts Power On Self-Test (POST), clears the memory, sets up input/output devices, and loads the operating system from the hard disk or ROM.

Century register: Stores the first two digits of the 4-digit year. It reads either "19" in 1999 or "20" in 2000 and is not updated automatically.

Date information: Chronological time information represented as days (DD), months (MM), years (YY), and century (CC).

Firmware: Programming that is inserted into read-only memory chips.

Operating system: Software that manages the physical and logical resources of the computer. The operating system software includes file management, process scheduling, and device interfacing.

POST: Power On Self Test. When the computer is turned on, POST routines instruct the CPU to initialize the memory and ultimately the entire system. POST inventories and tests system components, after which the boot process loads the operating system.

RTC: Real Time Clock. An RTC is a battery-powered clock that is included as part of a microchip in the computer hardware. It stores system description or setup values û including values for the year, month, date, hour, minutes, and seconds.

ROM: Read only memory. Memory contents that can be read but not altered without special programming devices. (Often referred to as firmware.)

System time: The time used within the operating system or applications. This may be different than the time presented by the PC's Real Time Clock and BIOS.

Time synchronization service: A program used to synchronize system time with an external time source such as another computer or an atomic clock.
