计算机论文代写：开放和封闭源代码的技术比较
近年来，总的趋势已经改变，越来越多的人正在转向开放源码软件。之前推出的开源和闭源软件之间的差异，重要的是要明白两手段。软件包括两部分，即源代码和目标代码。源代码是指逻辑上的书面声明，由编译器的帮助。源代码是不能直接使用的软件，但保持在编译的形式与编译器的帮助。这被称为目标代码的编译形式。这个代码是一个由软件应用。闭源软件是一个源代码是由供应商和用户只提供目标代码保存，因而限制了自由修改源代码。大多数时候，内部功能不能在闭源软件案例修改。同时，在开放源代码的情况下，该公司还提供了源代码，从而为用户提供更大的自由来修改和复制软件。闭源软件结果已经带来了新版本的每一次，新的软件所做的修改。但在最近的几次，闭源软件受到许多人的批评，因为人们认为大多数时候没有太多的旧版本和新版本，这是展示一个新的版本只是一个商业策略之间的差异比以前的版本更好的产品来增加其销售（麦科马克，2006）。本报告将最常用的操作系统：Windows和Linux带来了Windows和Linux的利益差异。Linux开放源软件在Windows已经闭源软件，是由微软。本报告将重点放在近年来的变化趋势。

In recent years, a general trend has changed as more and more people are shifting towards open source software. Before bringing out the differences between open and closed source software, it is important to understand what the two means. Software comprises of two parts i.e. source code and object code. A source code means logically written statements which are executed with the help of compiler. The source code is not used directly by the software, but is kept in a compiled form with the help of compiler. This compiled form is known as object code. This object code is the one which is used by the software. Closed source software is one where the source code is kept by the vendor and the user is only provided with the object code, thus restricting the freedom to modify the source code. Most of the time, internal functionality cannot be modified in case of close source softwares. While, in case of open source, the vendor also provides the source code, thus offering the user greater freedom to modify and copy the software. Closed source software as a result has to bring out new versions each time, new modifications are done on the software. But in recent times, closed source software has been criticized by many people because people feel that most of the time there is not much of difference between the old and new versions and it’s just a business strategy to showcase a new version as better product than previous version to increase its sales (MacCormack, 2006). This report will compare the two mostly used operating systems: Windows and Linux bring out the differences and benefits of Linux over Windows. Linux isopen source software while Windows has been closed source software which is owned by Microsoft. This report will also focus on the changing of trend in recent years.
