INTRODUCTION

Meaning of Open Source Software (OSS) Open source software (OSS) is defined as computer software for which the source code and certain other rights normally reserved for copyright holders are provided under a software license that meets the Open Source Definition or that is in the public domain. This permits users to use, change, and improve the software, and to redistribute it in modified or unmodified forms. Meaning of Hardware A computer's hardware consists of the physical components necessary to operate and interact with a computer.

Since a computer's primary language is binary, devices are necessary to convert our input into that language. The binary code coming out of the computer must also be translated into something usable for the operator. Meaning of Software Software is often divided into two categories:

1. System software: Includes the operating system and all the utilities that enables the computer to function.
2. Application software: Includes programs that do real work for users. For example, word processors, spreadsheets, and database management systems fall under the category of applications software.

Meaning of Pervasive Computing

Pervasive computing (also called ubiquitous computing) is the growing trend towards embedding microprocessors in everyday objects so they can communicate information. The words pervasive and ubiquitous mean "existing everywhere. " Pervasive computing devices are completely connected and constantly available. Pervasive computing relies on the convergence of  wireless technologies, advanced electronics and the Internet. The goal of researchers working in pervasive computing is to create smart products that communicate unobtrusively. The products are connected to the Internet and the data they generate is easily available.

Examples of Pervasive Computing Smart TV

Samsung Smart TV, which is also sometimes referred to as "Connected TV" or "Hybrid TV", (not to be confused with Internet TV, Web TV, or LG Electronics's upcoming "SMART TV" branded NetCast Entertainment Access devices), is the phrase used to describe the current trend of integration of the internet and Web 2. 0 features into modern television sets and set-top boxes, as well as the technological convergence between computers and these television sets /set-top boxes. These new devices most often also have a much higher focus on online interactive media, Internet TV, over-the-top content, as well as on-demand streaming media, and less focus on traditional broadcast media like previous generations of television sets and set-top boxes always have had.

The technology that enables Smart TVs is not only incorporated into television sets, but also devices such as set-top boxes, Blu-ray players, game consoles, and other companion devices. These devices allow viewers to search and find videos, movies, photos and other content on the web, on a local cable TV channel, on a satellite TV channel, or stored on a local hard drive.

Garmin GPS

The Global Positioning System (GPS) is a space-based global navigation satellite system (GNSS) that provides location and time information in all weather, anywhere on or near the Earth, where there is an unobstructed line of sight to four or more GPS satellites. It is maintained by the United States government and is freely accessible by anyone with a GPS receiver.

The GPS project was developed in 1973 to overcome the limitations of previous navigation systems, integrating ideas from several predecessors, including a number of classified engineering design studies from the 1960s. GPS was created and realized by the U. S. Department of Defense (USDOD) and was originally run with 24 satellites. It became fully operational in 1994. 6. 0

Conclusion

Open Source can be used by anyone and because it has no copyright claims, so users are free to use, change, and improve the software, and to redistribute it in modified or unmodified forms. Pervasive Computing is to make our lives easier because we can interact with computers. Besides that, we can easily give the computer commands and the computer will grant your wish.

The Latest Open Source Operating System (OS)

Meaning of Open Source OS

Open Source Operating System is the most important program that runs on a computer that is free to use, change, and improve the software, and to redistribute it in modified or unmodified forms. Every general-purpose computer must have an operating system to run other programs. Operating systems perform basic tasks, such as recognizing input from the keyboard, sending output to the display screen, keeping track of files and directories on the disk, and controlling peripheral devices such as disk drives and printers.

Examples of Open Source OS

a) Dream Linux. DreamLinux is a modern and modular Linux system that can be run directly from the CD and optionally be easily installed onto your HD. Dreamlinux comes with a selection of the best applications designed to meet mostly of your daily needs. It is based on Debian and Morphix, which means it takes advantages of their best features and adds its own modern development tools.

b) Haiku. Haiku is an open-source operating system currently in development designed from the ground up for desktop computing. Inspired by the BeOS, Haiku aims to provide users of all levels with a personal computing experience that is simple yet powerful, and free of any unnecessary complexities. Haiku is developed mostly by volunteers around the world in their spare time.

The Latest Open Source Application Software

Meaning of Open Source Application Software

Open Source Application Software includes database programs, word processors, and spreadsheets and others. It is free to use, change, and improve the software, and to redistribute it in modified or unmodified forms.

Examples of Open Source Application

Software Web Browser

Mozilla Firefox. A web browser is a software application for retrieving, presenting, and traversing information resources on the World Wide Web. An information resourceis identified by a Uniform Resource Identifier (URI) and may be a web page, image, video, or other piece of content. Hyperlinks present in resources enable users easily to navigate their browsers to related resources. The major web browsers are Internet Explorer, Mozilla Firefox, Google Chrome, Apple Safari, and Opera.

Spreadsheet

Microsoft Office Excel. A spreadsheet is a computer application that simulates a paper, accounting worksheet. It displays multiple cells usually in a two-dimensional matrix or grid consisting of rows and columns. Each cell contains alphanumeric text, numeric values or formulas. A formula defines how the content of that cell is to be calculated from the contents of any other cell (or combination of cells) each time any cell is updated. Spreadsheets are frequently used for financial information because of their ability to re-calculate the entire sheet automatically after a change to a single cell is made. A pseudo third dimension to the matrix is sometimes applied as another layer, or layers/sheets, of two-dimensional data.
