Event Driven Programming

Operating Systems are complex pieces of software that are designed for powerful hardware, easily capable of running many programs at once, the prioritize hardware task requests known as ‘system calls’ and allocate them memory space or processing time as needed.

M1 - Describe the features of an event driven language that make it suitable for creating a GUI

Process Improvement: regular analysis of all activities involved with the software to discover where improvements should be made

The Operating system is one most important parts of anything that runs on technology. It manages the computers memory and processes the information for the software and hardware. There is different operation system for pc, tablets, smart cars, and smartphones.

A computers operating system (OS) is the core of the computer and is more than just software. The OS controls the computer’s memory and processes as well as its hardware and software. It is the brain of the computer. Software applications on the other hand perform a certain task. Ex. Google Chrome provides internet and Adobe allows PDF files to be read (among other things). The OS is what makes all of these applications work successfully and accomplish whatever the application is designed to accomplish.

Graphical user interface, a GUI (pronounced as either G-U-I or gooey ) allows the use of icons or other visual indicators to interact with electronic devices , rather than using only text via the command line . For example , all versions of Windows utilize a GUI whereas MS-DOS does not . The GUI was first developed at Xerox PARC by Alan Kay , Douglas Engelbart , and a group of other researchers in 1981. Later , Apple introduced the Lisa computer , the first commercially available computer , on January

Event driven programs are also used in non-graphical applications as well such as real life objects like DVD Player, Microwaves Oven and washing machine also in operating systems such as CMD, PowerShell and

3. A Use Case is developed to support requirement specification. It is a detailed description of specifications in its simplest form using Realtime scenarios of the functionality requirements between the actors and

Operating systems were not in existence before the 1960s. The definition of operating systems is a program designed to run other programs on the computer and is the most important

29. In event driven architecture (EDA) the business unit "pushes" the event to the recipient rather than waiting for the recipient to request or "pull", the event. 
True    False

The operating system is the set of instructions that direct the computer to accomplish specific tasks such as document production and spreadsheet calculations.

ANSWER: Operating system exist on the grounds that they offer a sensible approach to tackle the issue of making a usable processing framework. The major objective of computer systems is to execute user programs and to make user issues simpler. Computer hardware is developed to this objective. Since exposed hardware alone is not simple to utilize, application programs are produced. These programs require basic operations, for example, those controlling the I/O devices. The regular capacities of controlling and assigning assets are then brought together into one bit of software: the operating system. Another way we

This paper will discuss three main operating systems, Windows, Linux, and OS X. All three of these operating systems have features which are unique unto themselves. Although there may be arguments as to which one of these three operating systems is better it really all comes down to what features are needed for each user. This paper will describe the features that each of these operating systems has to offer.

The interview session has been done by include an open-ended and closed-ended question which are related to the implemented project. Next, sampling technique is executed by system analyst who does evaluation to the current system or prototype. These processes give feedback in evaluation form that filled after tested the system. Lastly, observation is performed by using questionnaire form. According to Burch (1992), the questionnaire is analyzed and transform into structured form that easy to understand. After all information has been collected, structuring of system requirement takes place. It focused on development process modeling which perform “graphically representing the process, or actions, that capture, manipulate, store, and distribute data between a system and environment” (Hoffer, George, & Valacich, 2012, p. 182). In this step, Data flow diagram (DFD) is structured by system analyst using special tools and techniques to create a decision table. According to Hoffer, George and Valacich (2012), decision table is a “diagram of process logic where the logic is reasonably complicated” (p. 200). This table is useful to help system analyst to make a decision toward the project. Then all information’s gained from this phase are documented in System Analysis Report (SAR) that acts as a guideline or reference to the future system development project (Burch, 1992).

When you start a pc with an OS, it allows you to do projects like:
