This week’s lecture has been divided into two parts. In the first part, Prof. Alistair further explained Business Process Modelling with some specific examples. During the second half, a guest lecture provided information regarding gaming and graphic technology. In this weekly journal, firstly I will review some knowledge of Business Process Modelling, because we continuously discussed BPM in our tutorial. Secondly, I will focus on the gaming and graphic technology based on my understanding.
Business Process Modelling
Business Process Modelling refers to the methods, notations, grammars, tools and purposed of process modelling. Business Process Modelling Notation (BPMN) is presented as a business process modelling language. Its main objective is to increase awareness of the close link between business requirements and IT capabilities, and the related fundamental role of business processes. For example, within an organization, the manager could know that they have some operational technology and various business services with corresponding business processes. However, he may not totally understand capabilities of these services and technology. BPM aims to settle these kinds of problems.
Graphic Processing Unit
According to this week’s lecture, I know lots of knowledge about Graphic Processing Unit (GPU). After the lecture, I have searched online about GPU and tried to gather relevant information together. GPU is a concept relative to the CPU (central processing unit). In the modern computers, especially desktop’s system, graphics processing becomes more and more important. It needs a dedicated graphics core processor. GPU can accelerate the building of images and output high quality graphic display. For example, 10 years ago, we played first person shooting games with very rough images by using a computer. In contrast, 10 years later, some kinds of computer games, such as “Call of duty”, it represents excellent graphics display, because modern computers are equipped with GPU technology. GPU acts as a heart of graphical display card. It determines the class and most of performance of the graphics card.
For GPU’s computational functions, modern GPU uses most of their transistor to do calculations for 3D computer graphics. Recent development in GPU include support for programmable shaders which can manipulate vertices and textures with many of the same operations supported by CPUs, oversampling and interpolation techniques to reduce aliasing, and very high-precision color spaces. Because most of these computations involve matrix and vector operations, engineers. Scientists have increasingly studied the use of GPUs for non-graphical.
Last I have defined carsales.com.au, however I faced some problems with this service, for example, the pricing of using private car selling service. At last, I have figured out this question. During this week, I am continuously working on my assignment for identifying several services. For instance, I find SurveyMonkey is a kind of web-based service, and it can be identified as software component service, because it has survey templates for its users to generate online survey. It is also can be found that people use SurveyMonkey for everything from customer satisfaction and employee performance review, to course evaluations and research of all types. In addition, the pricing factor for SurveyMonkey is quite clear. It has four different plans including BASIC, SELECT, GOLD and PLATINUM with price of free, 19 AUD/month, 25 AUD/month and 65 AUD/month respectively. Further investigation of this service will be focus on functionality and some legal factors.
