INTRODUCTION TO COMPUTER SOFTWARE
The second component of an information system is software. Simply put: Software is the set of instructions that tell the hardware what to do. Software is created through the process of programming we will cover the creation of software in more detail in chapter Without software, the hardware would not be functional.
Software can be broadly divided into two categories: operating systems and application software. All computing devices run an operating system. The amount of memory that early operating systems could handle was limited as well, making large programs impractical to run.
In , Apple introduced the Macintosh computer, featuring an operating system with a graphical user interface. Though not the first graphical operating system, it was the first one to find commercial success. In , Microsoft released the first version of Windows.
This version of Windows was not an operating system, but instead was an application that ran on top of the DOS operating system, providing a graphical environment. It was quite limited and had little commercial success. It was not until the release of Windows 3. Since , both Apple and Microsoft have released many new versions of their operating systems, with each release adding the ability to process more data at once and access more memory.
Features such as multitasking, virtual memory, and voice input have become standard features of both operating systems. Linux is a version of the Unix operating system that runs on the personal computer. Unix is an operating system used primarily by scientists and engineers on larger minicomputers. These are very expensive computers, and software developer Linus Torvalds wanted to find a way to make Unix run on less expensive personal computers.
Linux was the result. Linux has many variations and now powers a large percentage of web servers in the world. It is also an example of open-source software , a topic we will cover later in this chapter.
Are you a Mac? Are you a PC? In the end, Microsoft successfully defended themselves. Over the past few years, Microsoft and Apple have traded barbs with each other, each claiming to have a better operating system and software. While Microsoft has always had the larger market share see sidebar , Apple has been the favorite of artists, musicians, and the technology elite. Apple also provides a lot of computers to elementary schools, thus gaining a following among the younger generation.
Why is this? On almost all college campuses, you see a preponderance of Apple Macintosh laptops. In elementary schools, Apple reigns as well.
Why has this not extended into the business world? As we learned in chapter 1, almost all businesses used IBM mainframe computers back in the s and s. When executives had to make a decision about purchasing personal computers for their employees, they would choose the safe route and purchase IBM. Microsoft soon found itself with the dominant personal-computer operating system for businesses. As the networked personal computer began to replace the mainframe computer as the primary way of computing inside businesses, it became essential for Microsoft to give businesses the ability to administer and secure their networks.
Microsoft developed business-level server products to go along with their personal computer products, thereby providing a complete business solution. The second major category of software is application software. Application software is, essentially, software that allows the user to accomplish some goal or purpose. For example, if you have to write a paper, you might use the application-software program Microsoft Word. If you want to listen to music, you might use iTunes.
To surf the web, you might use Internet Explorer or Firefox. Even a computer game could be considered application software. When a new type of digital device is invented, there are generally a small group of technology enthusiasts who will purchase it just for the joy of figuring out how it works. However, for most of us, until a device can actually do something useful we are not going to spend our hard-earned money on it. For the personal computer, the killer application was the spreadsheet.
It was an immediate hit and drove sales of the Apple II. It also solidified the value of the personal computer beyond the relatively small circle of technology geeks. Along with the spreadsheet, several other software applications have become standard tools for the workplace.
These applications, called productivity software, allow office employees to complete their daily work. Here is a list of these applications and their basic functions:. Microsoft popularized the idea of the office-software productivity bundle with their release of Microsoft Office. This package continues to dominate the market and most businesses expect employees to know how to use this software. However, many competitors to Microsoft Office do exist and are compatible with the file formats used by Microsoft see table below.
Recently, Microsoft has begun to offer a web version of their Office suite. Similar to Google Drive, this suite allows users to edit and share documents online utilizing cloud-computing technology. Cloud computing will be discussed later in this chapter. Two subcategories of application software worth mentioning are utility software and programming software. Utility software includes software that allows you to fix or modify your computer in some way. Examples include antivirus software and disk defragmentation software.
These types of software packages were invented to fill shortcomings in operating systems. Many times, a subsequent release of an operating system will include these utility functions as part of the operating system itself. Programming software is software whose purpose is to make more software. Most of these programs provide programmers with an environment in which they can write the code, test it, and convert it into the format that can then be run on a computer.
As presentation software, specifically Microsoft PowerPoint, has gained acceptance as the primary method to formally present information in a business setting, the art of giving an engaging presentation is becoming rare. Many presenters now just read the bullet points in the presentation and immediately bore those in attendance, who can already read it for themselves. The real problem is not with PowerPoint as much as it is with the person creating and presenting. Software developers are becoming aware of this problem as well.
Prezi is a presentation tool that uses a single canvas for the presentation, allowing presenters to place text, images, and other media on the canvas, and then navigate between these objects as they present. Just as with PowerPoint, Prezi should be used to supplement the presentation. And we must always remember that sometimes the best presentations are made with no digital tools. When you purchase software and install it on your computer, are you the owner of that software?
Technically, you are not! When you install software, you are actually just being given a license to use it. When you first install a software package, you are asked to agree to the terms of service or the license agreement.
In that agreement, you will find that your rights to use the software are limited. This agreement only gives you some rights to use the features included in the software edition you licensed. For the most part, these restrictions are what you would expect: you cannot make illegal copies of the software and you may not use it to do anything illegal. However, there are other, more unexpected terms in these software agreements. For example, many software agreements ask you to agree to a limit on liability.
You can recover from Microsoft and its suppliers only direct damages up to the amount you paid for the software. You cannot recover any other damages, including consequential, lost profits, special, indirect or incidental damages. As the personal computer proliferated inside organizations, control over the information generated by the organization began splintering.
Say the customer service department creates a customer database to keep track of calls and problem reports, and the sales department also creates a database to keep track of customer information. Which one should be used as the master list of customers?
As another example, someone in sales might create a spreadsheet to calculate sales revenue, while someone in finance creates a different one that meets the needs of their department. However, it is likely that the two spreadsheets will come up with different totals for revenue. Which one is correct?
And who is managing all of this information? The enterprise resource planning ERP system sometimes just called enterprise software was developed to bring together an entire organization in one software application. Simply put, an ERP system is a software application utilizing a central database that is implemented throughout the entire organization. ERP systems were originally marketed to large corporations.
However, as more and more large companies began installing them, ERP vendors began targeting mid-sized and even smaller businesses. In order to effectively implement an ERP system in an organization, the organization must be ready to make a full commitment. All aspects of the organization are affected as old systems are replaced by the ERP system.
In general, implementing an ERP system can take two to three years and several million dollars. In most cases, the cost of the software is not the most expensive part of the implementation: it is the cost of the consultants! So why implement an ERP system? If done properly, an ERP system can bring an organization a good return on their investment. By consolidating information systems across the enterprise and using the software to enforce best practices, most organizations see an overall improvement after implementing an ERP.
SOFTWARE & ITS TYPES.
The second component of an information system is software. Simply put: Software is the set of instructions that tell the hardware what to do. Software is created through the process of programming we will cover the creation of software in more detail in chapter Without software, the hardware would not be functional. Software can be broadly divided into two categories: operating systems and application software. All computing devices run an operating system.
What is software and types of software with examples?
Software is a collection of instructions and data that tell the computer how to work. This is in contrast to physical hardware , from which the system is built and actually performs the work. In computer science and software engineering , computer software is all information processed by computer systems , including programs and data. Computer software includes computer programs , libraries and related non-executable data , such as online documentation or digital media. Computer hardware and software require each other and neither can be realistically used on its own.
At present, there are a plethora of high-tech technologies along with software accessible to the people which outline the certain way we all lead our lives and also houses are constantly changing as well as increasing needs and demands. So, what is software, and what are the types of software that exist today? A software or computer software essentially a type of programs which enable the users to perform some particular specific task or actually used to operate their computer. It essentially directs all of the peripheral devices on the entire computer system- what exactly to do and how exactly to perform a task. A software plays a key role of a mediator between the user and the computer hardware.
The Five Types of Systems Software
Software is a set of programs, which is designed to perform a well-defined function. A program is a sequence of instructions written to solve a particular problem. The system software is a collection of programs designed to operate, control, and extend the processing capabilities of the computer itself. System software is generally prepared by the computer manufacturers. These software products comprise of programs written in low-level languages, which interact with the hardware at a very basic level. System software serves as the interface between the hardware and the end users. Application software products are designed to satisfy a particular need of a particular environment.
Every day, we come across different types of computer software that helps us with our tasks and increase our efficiency. From MS Windows that greets us when we switch on the system to the web browser that is used to surf the internet or the games that we play on our computer to the calorie burn counter on our smartphone, are all examples of software. In this world of technology, we even come across various software development trends that help our business to grow, we are surrounded by all these software which are determined to make our lives easier.
Computer system comprises of two main components Hardware physical and Software non — physical or set of instructions. Their hardware is also different. Similarly for different types of tasks we have separate software like System software, application software etc. System software is of three main types :. Go through Operating system which is a system software given on page no.
It may also be digital library management software which will manage the digital resources of the library or some other types, say a Learning Management System or Content Management System, etc. Software is the program that run the computer and allows us to use it. These application suites, as you know, come as bundles of application … It consist of a group of applications combined to perform related function. Share it! Application Software is he type of software which runs as per user request.
Вы промыли ей мозги. Вы рассказываете ей только то, что считаете нужным. Знает ли она, что именно вы собираетесь сделать с Цифровой крепостью. - И что .
- Ну, что еще - до того как вы отправитесь домой.
Травматическая пуля, - задумчиво повторил Беккер. - Вот откуда шрам. - Весьма сомнительно, чтобы Танкадо связал свои ощущения с выстрелом. - И все же он отдал кольцо, - сказал Фонтейн. - Вы правы, сэр.
Человек, в течение многих лет одерживавший победу над опаснейшими противниками, в одно мгновение потерпел поражение. Причиной этого стала любовь, но не. Еще и собственная глупость. Он отдал Сьюзан свой пиджак, а вместе с ним - Скайпейджер.
