To accomplish this monitoring, application software must check sensors located throughout the reactor. If any safe operating values are exceeded, the software takes action, such as injecting cooling water or shutting the reactor down by inserting control rods. Advantages of proprietary software: You can get exactly what you need in terms of features, reports, and so on. Being involved in the development offers control over the results. You can modify features that you might need to counteract an initiative by competitors or to meet new supplier or customer demands.
An application programming interface API is a set of programming instructions and standards for one software program to access and use the services of another software program. Operating systems use the following five basic task management techniques to increase the amount of processing that can be accomplished in a given amount of time: Allows two or more users to run programs at the same time on the same computer.
Some operating systems permit hundreds or even thousands of concurrent users. The ability of the computer to handle an increasing number of concurrent users smoothly is called scalability. Supports running a program on more than one CPU. Allows more than one program to run concurrently.
Allows different threads of a single program to run concurrently. A thread is a set of instructions within an application that is independent of other threads. For example, in a spreadsheet program, the thread to open the workbook is separate from the thread to sum a column of figures. Real time: Responds to input instantly. To do this, the operating system task scheduler can stop any task at any point in its execution if it determines another higher priority task needs to run immediately.
Such systems are used to control the operation of jet engines, deployment of air bags, the operation of anti-lock braking systems, and other real-time operations. The Linux distributor takes the code from different programs and combines it into a single operating system that can be installed on a computer.
The distributor may also add finishing touches, such as what the desktop looks like, what color schemes and character sets are displayed, and what browser and other optional software is included with the operating system.
One of the greatest advantages of using a bit version computer is the ability to access physical memory RAM above the 4-gigabyte GB range, which is not addressable by bit computers. The 4-GB limit can be a severe problem for servers and computers accessing large databases. An embedded system is a computer system including some sort of processor that is implanted in and dedicated to the control of another device.
Embedded systems control many devices in common use today, including TV cable boxes, cell phones, digital watches, digital cameras, MP3 players, calculators, microwave ovens, washing machines, and traffic lights.
The term cloud computing refers to the use of computing resources, including software and data storage, on the Internet the cloud rather than on local computers. Rather than installing, storing, and running software on your own computer, with cloud computing, you use the Web browser to access software stored and delivered from a Web server.
Typically the data generated by the software is also stored on the Web server. Cloud computing provides the benefit of being able to easily collaborate with others by sharing documents on the Internet. Cloud computing involves some risks, however.
Workgroup application software is designed to support teamwork, whether people are in the same location or dispersed around the world.
This support can be accomplished with software known as groupware that helps groups of people work together effectively. Examples of workgroup software include group scheduling software, electronic mail, and other software that enables people to share ideas. Middleware is software that allows various systems to communicate and exchange data. Middleware is often developed to address situations where a company acquires different types of information systems through mergers,.
Discussion Questions 1. Such obsolete hardware can place an organization at a competitive disadvantage. Managers, no matter what their career field and educational background, are expected to help define the business needs that the hardware must support. In addition, managers must be able to ask good questions and evaluate options when considering hardware investments for their areas of the business.
This need is especially true in small organizations, which might not have information system specialists. Software upgrades are an important source of increased revenue for software manufacturers and can provide useful new functionality and improved quality for software users.
It could be argued that with no hard disk, thin clients never pick up viruses or suffer a hard disk crash. Unlike personal computers, thin clients download software from a network when needed, making support, distribution, and updating of software applications much easier and less expensive. The filament comes in spools of various colors and is fed through a heated extruder that moves in several directions to place layer upon layer on top of each other until the object is created.
Responses will vary. Tablet computers often include a variety of software and communications capabilities. Most can communicate with desktop computers over wireless networks. A smartphone combines the functionality of a mobile phone, camera, Web browser, e-mail tool, MP3 player, and other devices into a single handheld device.
Important operating system features could be an attractive, easy to use user interface, file protection, system restore capabilities, security features, such as a security center and firewall, and troubleshooters. Note that providing one high-quality SaaS application to thousands of businesses is much more cost-effective than custom designing software for each business.
SaaS does involve some risks. It can also be difficult to integrate the SaaS approach with existing software. The student might recommend a sight interface, which uses a camera on the computer to determine where a person is looking on the screen and performs the appropriate command or operation. For most companies, the spheres of influence are personal, workgroup, and enterprise. Information systems that operate within the personal sphere of influence serve the needs of an individual user.
These information systems enable their users to improve their personal effectiveness, increasing the amount of work they can do and its quality. Such software is often referred to as personal productivity software. A workgroup is two or more people who work together to achieve a common goal. An information system that operates in the workgroup sphere of influence supports a workgroup in the attainment of a common goal. Information systems that operate within the enterprise sphere of influence support the firm in its interaction with its environment.
Sources of application software are proprietary software and off-the-shelf software. An advantage of proprietary software is that you can get exactly what you need in terms of features and reports.

Data Loss Company was facing problem of data lost or misplaced if scattered data is lost because of power failure or any other cause there was no means to retrieve it back. Retention Total work was manual so more man power was required, if a person who take care of the data leaves the job it was very hard for a new person to understand and maintain the data.
Comment 0. View a full sample. As the difference among computer manufacturers in the arenas of price and performance narrows, support for green computing is emerging as a new business strategy for these companies to distinguish themselves from the competition.
Application software is a set of programs designed to coordinate the activities and functions of the hardware and various programs throughout the computer system.
Information systems that operate within the workgroup sphere of influence support a firm in its interaction with customers, suppliers, shareholders, competitors, special-interest groups, the financial community, and government agencies.
A True 5. B False Answer: To run, applications request services from the operating system through a defined application program interface API. The operating system controls how memory is accessed and maximizes available memory and storage. An operating system with multiuser capabilities allows two or more users to run programs at the same time on the same computer.
Individuals and organizations can use the open-source Linux code to create their own distribution of Linux. Utility programs help to perform maintenance, correct problems, merge and sort sets of data, keep track of computer jobs, and compress files of data.
Middleware is software that allows various systems to communicate and exchange data. Application software applies the power of a computer to give individuals, workgroups, and the entire enterprise the ability to solve problems and perform specific tasks.
Software as a Service SaaS allows businesses to subscribe to Web-delivered application software by paying a monthly service charge or a per use fee. A software suite is a collection of programs packaged together as a bundle and typically includes a word processor, spreadsheet program, graphics program, and more.
There are Web-based productivity software suites that require no installation on the computer. Cloud computing refers to the use of computing resources, including software and data storage, on local computers.
A True B False 7. Today, programmers often use visual and object-oriented languages to write new business applications. Software upgrades vary widely in the benefits that they provide, and what some people call a benefit others might call a drawback.
