The vendor must design and implement the software specifically for that customer, hence the name “customized” (Sommerville, 2016:21). Examples of customized software include control systems for electronic devices, specific business processes and air traffic control systems.
The main difference between generic and customized software is that generic products are controlled by the vendors whereas customized are controlled by the organisation buying the software. In terms of specifications, generic specifications are done by the vendors whereas customized specifications are done by the organisation buying the system; the organisation will outline specific requirements and their needs.
Definition of Software engineering According to Sommerville (2016:21), software engineering is defined as an engineering discipline that is concerned with all aspects of software production from the early stages of system specification through to maintaining the system after it has gone into …show more content…
A high-quality software must be produced.
There are two reasons why software engineering is important:
• It is cheaper to use software engineering methods in the long run, since most individuals and society rely on advanced software systems.
• Reliable, efficient, trustworthy and economically sound systems must be produced by software engineers. If good software engineering practices are not followed, this could lead to higher costs for testing the software, quality assurance (meeting standards) and long term maintenance.
Software engineering makes use of software processes. According to Sommerville (2016:23), a software process refers to a sequence of activities that lead to the production of a software product. There are four fundamental activities which are commonly used in software processes:
a) Software specification – this is the stage where software engineers and customers sit down to define the software to be produced and constraints on the software.
b) Software development - this is the programming of a software by the development

Kaylee Le MIS 201 U2 Assignment 10/18/2015 CERT/CERT-CC The development and dependence on the internet, and also complexity of interloper skills, additional resources is on demand. To fulfill this demand, the CERT/CC became one part of the larger CERT Division. The CERT is stand for the coordination center of the computer emergency response team (CERT) for the Software Engineering Institute (SEI). The CERT Division is funded mostly by the U.S. Department of Defense and the Department of Homeland Security.
Iterative and incremental approach is a better way of developing requirements and modules as well. 4. Requirements provide a complete operating picture of the solution, which helps in taking correct decisions during initial stages of software development life cycle (SDLC). Iterative and Incremental Approach This approach allows us to make changes before it is too late.
One of biggest roadblock that companies have to face is to invest a lot of money on implementing a software system and have employees ignore it and keep trying to do the task in their own way. This the reason why the provider that you choose for implementing your software have to be a natural fit for the organization. If the owners and employees have the same passion and understanding of the product that they would implement the result would be a success (Phillips, 2016).
In this modern world the need for designing and developing an application with good secure features is very high. I have also learned what an error exceptional handling is and why is it important in code review. I have also learned that in developing a software product or in the software development life cycle process, a software product must be teste in earlier stages and very frequently. This recalled my knowledge of secure software development life cycle. One must know the importance of secure software development life cycle.
The introduction of personal computers in the 1980s and 1990s revolutionized the way that people worked and communicated, allowing for greater efficiency and productivity. The widespread adoption of personal computers during this time period led to the creation of new industries such as software development and computer
So, when somebody create communication systems and, he has to take into mind considerations. He has to make sure there are no dangers for the user. It should as much secure as possible. If something goes wrong or damage the user in any way, the system editor should be blamed. Many people use computers for a long period of time which can lead to some physical and mental problems.
Sharing Internet Access: within a computer network learners are able to access the internet at once. Speed: Using a network is a faster way for sharing and transferring files. Without a network, files are shared by replicating them to a floppy disk. Cost: Networkable versions of many popular software programmes are available at significant savings compared to buying individual licensed copies. It also allows easier upgrading of the program.
Software updating If you want to protect your computer from any malicious activities, therefore, you should update your computer security software regularly. It is very important to update a software security software because some weakness software may allow a hacker or viruses to gain access to your computer. Moreover, update a software can able to make your computer faster. If you do not update the security software that means there will be changes to get attacks by hackers and viruses so you should update a security software regularly.
This approach centers on people, communications, the anticipated product and its flexibility. The concept of this approach is similar to that of the traditional management approach: generating plans and requirements, evolving the anticipated product, incorporating it with other products as required then testing it and debugging technical hitches if any is found, then lastly fitting it for use (Rose, 2010). In this approach, as a replacement for focusing on the phases all at once like it is done in the traditional approach, the entire project is fragmented into smaller segments known as scrums after which the scrums are taken as smaller projects and dealt with according to the traditional
Unit 2 discussion Assignment Using one of the referenced website articles discuss how OS creates the illusion of virtualization by virtualizing the CPU. By running one process, then stopping it and running another, and so forth, the OS can promote the illusion that many virtual CPUs exist when in fact there is only one physical CPU (or a few). last week we learn and discussed about one of basic and fundamental concepts and what about of the operating system and in generally how it 's working and it 's own component that related to complete the work as a group like a team. from this perspective, I would use one of the reference website articles that given for this week and introduced to the concepts of operating systems and discuss one of the most fundamental abstraction that the operating system provides to us to use .
It is important to emphasize that these challenges were brought about by poorly defined goals and the scope was usually unclear. This meant the projects usually tended to go beyond the estimates as the project developers tried to fix newly developed ideas in to the development process. the phase gate model was developed to give an outline of the project development process to offer solutions for managing newly launched
the more options there and can be used to violate privacy. Most people consider they have little, if any, control over their personal data. Better encryption and the minimizing of data requirements aids in this goal. PIMS systems are a new technological developing that promises to aid the privacy dilemma. The PIMS system consists of a user’s server, running the services selected by the user, storing and processing the user’s data locally instead of on an online server.
In the times of modern design, art and design has already become a part of our life and plays important roles in our society. Design not only decorates our society and living places, but also brings us a well-rounded life and makes our life become more colourful. Design is a great benefit that would not cause any negative issues to our society. So can you imagine how boring and dull will be if does not exist any art and design in our daily life? Can you imagine how our life will be in the future?
A computer-based information system (CBIS) is an information system that uses computer technology to perform different functions. For example, the google uses internet to accomplish its task, to reach its customers. Computer Based Information System is a field of studying computers and algorithmic processes including their applications. Such a system can include personal computer and software. It aims to support operations, management, and decision making.
