This is the complete unit history of the ADC, from 1948 to 1980. Sections include an overview of air defense in the United States from the end of World War I through the Cold War Era, a chronology... More > of changes in ADC organization, and individual lineages for all the ADC units. The latter includes ADCOM regions, Air Divisions, Air Defense Sectors, Centers, Wings, Groups, Air Force Bands, Squadrons, Flights, and Schools.< Less
An application delivery controller (ADC) is a network device in the datacenter that helps perform common tasks done by web sites in an effort to remove load from the web servers themselves. Many also... More > provide load balancing. They usually sit between the firewall
outer and the web farm. The ADC is in many cases described as the next generation load balancer. They tend to offer more advanced features such as content manipulation, advanced routing strategies as well as highly configurable server health monitoring. ADCs tend to offer features like compression, cache, connection multiplexing, application layer security, SSL offload, content switching combined with basic server load balancing.
This book is your ultimate resource for Application Delivery Controller (ADC). Here you will find the most up-to-date information, analysis, background and everything you need to know.< Less
All electrical signals in nature are analog and since most of the signal processing is done in the digital domain, Analog to Digital (ADC) and Digital to Analog (DAC) converters have become a... More > necessity. Flash ADC makes all bit decisions in a single go while Successive approximation ADC makes single bit decision at a time. Flash ADCs are faster but area increases exponentially with bit length while successive approximation ADC is slow and occupies less area. Between these two extremes, many other architectures exist, deciding a fixed number of bits at a time such as pipeline and multistep ADCs. They balance circuit complexity and speed. For medium speed and with high resolution, pipeline ADCs are promising.
Although many pipelined ADC architectures are discussed in literature, the number of bits/stage was always seen to be a designer’s choice.< Less
