In ER notation, the conceptual model is described with an ER Diagram in which entities represent concepts, cardinality and optionality represent relationships between concepts. A compiler is a program that accepts a source program in a high-level language and produces a corresponding object program. Agree The contents of these memory chips can be instantly changed to store new data. Observability of a real system does not mean it is being, or has been, observed. It provides an interface between the computer hardware and the programmer that simplifies and makes it feasible for coding, creation, debugging of application programs.

RISC processor designs optimize a CPUs processing speed by using a smaller instruction set. (Work breakdown) endobj Characteristics of Computer System involve Speed, Accuracy, Diligence, Versatility, Reliability, Automation, Memory. This is a major departure from the traditional design of current computers, called the Von Neuman design, which executes instructions serially (one at a time). The behaviour of physical systems manifests itself as flows and exchanges of matter, energy and information, and interaction through force fields. Instead of having one CPU with a single control unit and arithmetic-logic unit, the CPUs of these computers contain several type of processing units.
