<p class="abstract"><span lang="EN-US">Today we live in a society of high technologies, advanced information and com-munication systems in every field, including education. So, in modern education, teachers make full use of the possibilities of modern Information and Communi-cation Technologies (ICT). In this case, the attitude of the teachers towards the use of computers, to achieve the educational goals, is very important. To have the technologies sustained and significant effect, students in secondary and higher schools need to understand how to use them. The goal of this article is to help of students in secondary and higher schools to acquire enough practical program-ming skills and to learn the sorting algorithms, i.e. the article considers basic sort-ing algorithms. We developed and describe here software with name “Visual sorting” that shows visual, the execution of the basic sorting algorithms: Bubble sort; Selection sort; Insertion sort; Merge sort. Also, our software provides inter-active tracking of the performance (step by step) of different sorting algorithms.</span></p>

It is common knowledge in Information Technology (IT) that an embedded system is based on microprocessor and is built to control a function or a range of functions. Although, it is not designed to be programmed by the end user in the same way that a PC is, it is designed to perform one particular task with choices and different options [1-5]. Multitasking is a method by which multiple tasks, also known as processes, share common processing resources, such as CPU. The main aim of this paper is analysis of the design of the embedded systems and a focus on mid-level abstractions for concurrent programs.
