CS703: Advanced Operating Systems notes
What is an Operating System?
An operating system (OS) is a program that, after downloading the first program, controls all other applications. An operating system is the most important software that runs on a computer. It controls computer memory and processes, as well as all of its software and hardware. It also allows you to communicate with a computer without having to speak a computer language. Without the operating system, the computer is useless.
A Top-Down Approach
The approach to the top (also known as step-by-step design and step-by-step improvement and in some cases using the same word decay) is actually a system partition to gain insight into its sub-systems named in retrospective engineering. Looking up and down the whole system view is built, specified, but not specified, any sub-level systems. Each sub-system is then filtered with additional details, sometimes at multiple levels of the sub-system, until all specifications are reduced to basic features.
Bottom-Up Design Approach
The way up is to integrate systems to create complex systems, thus making real systems into smaller parts of an emerging system. Low-level processing is a form of processing information based on incoming data from nature to form an idea. In this design, each component of the system is specified in detail. The parts are connected to make large parts, which are then reassembled until a complete system is created. An object-focused language such as C ++ or java uses a downward spiral when each object is first identified.
