However, software development does not catch up with hardware at this time. Designing programs for multi-processor computers is still a difficult task and requires a lot of experiences and skills. Besides, a big number of legacy programs that are designed for single-processor computers are still running and need to be parallelized for better performance. All these facts require a good approach for program parallelization. Compiler that automatically parallelize source code into executable code for multi-processor comput- ers is a very promising solution to this challenge.
The end user will need the understanding of how to run queries, generate reports, and update the database if their security level allows. In addition to the complexity of the software, the hardware required can be complex. Most modern day database management systems require a mainframe to house the database management
Reusability is one of the more influential capabilities when using OOP, as this task is much simpler done using OOP, then other programming languages ("IBM Smalltalk Tutorial", 2014). Both Procedural Programming and Object-Oriented Programming have positive and negative contradictions to each programming type. However, both programming types can be used singularly, and can be used in collaboration with each other, thus filling in the gaps, and creating the possibility of an extremely exceptional programming experience.

There are various techniques of arranging a coprocessor alongside a microprocessor. One technique is to provide the coprocessor with an instruction interpreter and program counter. Each instruction fetched from memory is examined by both the MPU and the coprocessor. If it is a MPU instruction, the MPU executes it; otherwise the coprocessor executes it. It can be seen that this solution is feasible, but by no means simple, as it would be difficult to keep the MPU and coprocessor in step.
Procedural Programming Procedural programming works like a step by step guide. You have to create a sequence of instructions which tells the computer what to do first, second, third and so on. Examples of a procedural programming language would be Pascal, Turbo Pascal and Basic. Procedural programming would be used when it is necessary to complete steps in a program and is only used when a user is about to do a certain task. An example of a procedural programming scenario would be that if a user has to enter their details into a form in order to move onto the next step such as you need to login first so you can confirm your order then this would require procedural programming.
Since a class defines only the data it needs to be concerned with, when an instance of that class (an object) is run, the programme will not be able to accidentally access other program . This characteristic of data hiding provides greater system security and avoids unintended data corruption. The definition of a class is reusable not only by the program for which it is initially created but also by other object-oriented programs (and, for this reason, can be more easily distributed for use in networks). The concept of data classes allows a programmer to create any new data type that is not already defined in the language
 This however, does not limit the 8051’s efficiency. Among the specs mentioned above, a typical 8051 microcontroller’s CPU introduced a built in Boolean processor. This Boolean processor allows the reduction of code size through bit-level Boolean logic operations which are carried out on selected internal registers and selected RAM locations. Therefore, greater efficiency can be found in programs that deals with binary input and output conditions commonly found in digital-control problems. The four registers of the 8051 further improves efficiency by reducing the time which it takes to execute an interrupt.
The alternative is for the operating system (OS) to manage placement through the policies and mechanisms of the virtual memory subsystem. In such a system, the task of the OS-level memory management software is to determine and find out when to reference memory remotely, and when to move or copy a page to a frame in the local memory of the processor. In 1993, system reliability analysis became important as well as complex. Although component-level analysis was well understood, system level models were difficult to develop. The behavior of the system under real workloads was extremely difficult to predict and model.
This definition includes all views of the source code and covers the parts of algorithm animation, which includes object (i.e. variable values, object states) visualisation and source code visualisation that can be static (compile time) in nature or dynamic (run time) in nature. Some applications of Java source code visualization contains debugging the source code, evaluating and improving program implementation, flow of algorithms, understanding program behaviour and teaching. Understanding a specific programming language can be a difficult and complicated task. One of the main reasons behind this is that students have difficulty in comprehending what a computer is actually doing when executing a program line and what is simultaneously happening in the memory.
Over the years, computer science kept evolving; leading to the emergence of what has become a standard in modern software development: Multitasking. Whether logical or physical, it has become a requirement for today's programs. In order to make it possible it became necessary to establish the notion of concurrency and scheduling. In this essay, concurrency will be discussed as well as two types of scheduling; pre-emptive used in threads and cooperative used in agents, their similarities and differences. Concurrency is an essential part of multitasking; after all using concurrency signifies executing several tasks at the same time or at least to give that impression, “Concurrency is an illusion of parallelism.
