A high-level programming language developed in the late 1970s and early 1980s for the United States Defense Department. Ada was designed to be a general-purpose language for everything from business applications to rocket guidance systems. One of its principal features is that it supports real-time applications. In addition, Ada incorporates modular techniques that make it easier to build and maintain large systems. Since 1986, Ada has been the mandatory development language for most U.S. military applications. In addition, Ada is often the language of choice for large systems that require real-time processing, such as banking and air traffic control systems.
Ada is named after Augusta Ada Byron (1815-52), daughter of Lord Byron, and Countess of Lovelace. She helped Charles Babbage develop programs for the analytic engine, the first mechanical computer. She is considered by many to be the world’s first programmer.

- Advanced Programmable Interrupt Controller
Abbreviated as APIC, an Advanced Programmable Interrupt Controller is a PIC used to extend the number of IRQs available, has more available interrupt lines that a typical PIC and also supports distributed CPUs. APIC must be implemented on the motherboard and also supported by the operating system. APIC differs from PIC as it offers multiple […]
The name given to the user interface (UI) for Windows Vista operating system. The interface is referred to as Aero Basic, and Vista also offers a second version called Aero Glass which provides even more graphics intensive features but requires a 3D video card that supports DirectX 9, and it must have a Longhorn Display […]
- After Power Failure
In computer BIOS settings for Intel desktop boards, After Power Failureis a power management option that will set the mode of operation if a power loss occurs. Users can select the following settings: Stay Off: Keeps the power off until the power button is pressed. Last State: Restores the previous power state before power loss […]
A WLAN networking device by Apple Computer. It is based on Wi-Fi standards ( IEEE 802.11b) and is compatible with other 802.11b devices. Similar devices from Apple Computer that are based on the IEEE 802.11g specification are called AirPort Extreme.
