operating system? An operating system serves as a hardware/software interface‚ acts as a repository for common‚ shared routines and defines a platform for constructing and executing application software. 2. An operating system presents an application programmer with a relatively "friendly" hardware/software interface. What does this mean? Why is it important? The user interface‚ sometimes called the shell‚ provides a mechanism for the user and application programs to communicate with the operating system

on a computer with a different type of central processing unit (CPU). 3RD GENERATION (HIGH LEVEL LANGUAGE ): The lack of portability between different computers led to the development of high-level languages—so called because they permitted a programmer to ignore many low-level details of the computer’s hardware. Hence‚ in the mid-1950s a third generation of languages came into use. These algorithmic‚ or procedural‚ languages are designed for solving a particular type of problem. Unlike machine

Task 1: Managing Projects (P1‚ P2‚ P3 and M1) a) Project Life Cycle (PLC) In this task I am going to cover PLC‚ resources issues and relate to projects. The Project Life Cycle refers to a logical sequence of activities to complete the project’s goals or objective. Every project goes through a series of stages during its life and a project life cycle involves four stages that are shown on the diagram bellow. Project activities must be grouped into stages to make it easy for the project manager

the structural conventions of programming‚ but is intended for human reading rather than machine reading. A programmer who needs to implement a specific algorithm‚ especially an unfamiliar one‚ will often start with a pseudocode description‚ and then "translate" that description into the target programming language and modify it to interact correctly with the rest of the program. Programmers may also start a project by sketching out the code in pseudocode on paper before writing it in its actual language

side effects are rarely used. Functional languages such as Standard ML ‚ Scheme and Scala do not restrict side effects‚ but it is customary for programmers to avoid them. [3] The functional language Haskell restricts side effects with a static type system ; it uses the concept of monads to do stateful and IO computations. [4] [5] Assembly language programmers must be aware of hidden side effects — instructions that modify parts of the processor state which are not mentioned in the instruction’s mnemonic
