Unit 3 Research Assignment 1 PT1420 Exploring Reverse Engineering Reverse engineering in computer programming is a technique used to analyze software in order to identify and understand the parts it’s composed of. The usual reasons for reverse engineering a piece of software are to recreate the program, to build something similar to it, to exploit its weaknesses or strengthen its defense. A reverse engineering advantage could be that one can repair certain bugs, see how a program operates

share data between them and they depend on each other only to take input and give output. In layered architecture of Network Models, one whole network process is divided into small tasks. Each small task is then assigned to a particular layer which works dedicatedly to process the task only. Every layer does only specific work. I have chooses application layer from the OSI model because the world experiences the Internet through the use of the World Wide Web, e-mail, and file-sharing programs. These
