BIOS (BASIC INPUT OUTPUT SYSTEM)
BIOS is an acronym for Basic Input Output System. It is the program that stores configuration details about your computer hardware and enables your computer to boot up. Every time your computer is switched on the BIOS loads configuration data into main memory, performs a routine diagnostic test on your hardware, then loads the operating system. Every computer has BIOS. There are many types but the most common type of BIOS 's come from: AMI, Award and Phoenix.The BIOS tells the operating system in your computer how to boot up, where to load everything, what to load, whats memory and CPU are present and much much more.
POST (POWER ON SELF TEST) .
The Power On Self Test is activated by the BIOS. It runs a series of checks and diagnostics on your motherboard. Some of the items it checks are, keyboard, CPU, memory, PCI slots etc. Keep in mind most POST problems are related to memory.
SEMANTIC WEB .
The Semantic Web is a mesh of information linked up in such a way as to be easily processable by machines, on a global scale. You can think of it as being an efficient way of representing data on the World Wide Web, or as a globally linked database.
The Semantic Web was thought up by Tim Berners-Lee, inventor of the WWW, URIs, HTTP, and HTML. There is a dedicated team of people at the World Wide Web consortium (W3C) working to improve, extend and standardize the system, and many languages, publications, tools and so on have already been developed. However, Semantic Web technologies are still very much in their infancies, and although the future of the project in general appears to be bright, there seems to be little consensus about the likely direction and characteristics of the early Semantic Web.
