Systems Programming and Component Based technologies -- 2

Task 1: An assembler interprets computer programs from assembly language to machine language. It can be used by developers to manage the computer’s hardware. It is also considered as an interface between highlevel languages and machine language. Compare and contrast between machine dependent and machine independent features of the assembler. Support your answer with examples of assembly code and their explanation. Note: The word limit is 400-500 words ====== Task 2: Distributed systems are becoming more popular with the growth of computer networks. Applications and part of applications must have portability attributes to run on different machines and different frameworks. Java is an object oriented programming language that is known for its portability a well as other advantages such as neutrality and reliability. With reference to at least one publication, analyze the Java compiler and environment and how it addresses the portability of applications. Note: The word limit is 400-500 words. ====== Task 3: Optimization is the fifth stage of the compiler that enhances the performance of code by increasing its speed and reducing the usage of resources. 1) Select a portion of code written in a programming language of your choice and apply four types of optimization techniques on it. 2) Explain the applied techniques and their impact on the performance. Note: The word limit is 250-300 words (without considering the example of code).
