Open-source programs always include source code for those interested in peering into how the program does what it does and possibly contributing to the development effort. The software and source code are available without cost or obligation. Open-source models vary by source-code-license terms. Source-code licensing only matters if you intend to modify or reuse the source code in any way. These issues are not relevant to most of us.
"A History Of Microsoft Windows"). By using a computer mouse and clicking on icons a user could run programs. This made computers very friendly and improved greatly on the user-computer relationship. Now computers could be used in every aspect of life. According to Shelly O’Hara in "Fifty Things You Must Know About Windows" by 1990 because of Windows and later versions of Windows 75% of all American homes owned a computer.
Linux is consider one of the operating system. The history, process, memory management and security operations are of (Linux) operating system will be highlight in this essay. Firstly, has a very interesting history for Linux operating system. It has developed and grown with a number of benefits for the users. Stallings & T (2009) defined " Linux, is free operating system and it is open source, provides all the advantages of operating system, where from multitasks, virtual memory,
My new target market for floppy disk would be museums specifically electronic museums. There are a few electronic museums worldwide and they could use these floppy’s’ for props and educational purposes. These museums promote and encourage the study of science and engineering using electronic heritage to educate and inspire students and the public. Electronic museums collects, preserves, exhibits, and makes available for research various artifacts, documents, and publications related to development of defense and other key electronics systems and the commercial products derived from them. Each museum provides visitors with an appreciation of the evolutionary milestones in electronics that led to the sophisticated products in use today, and honor the achievements of the pioneers who made these advancements possible.

Manages Applications – each OS installs, uninstalls, runs applications and manages the interface to the hardware for an application. 4. Manages Hardware – each OS manages the permanent programs and memory. All three OS’s also diagnose software and hardware problems and interpret the needs of each. With the similarities in the forefront of our minds, let us delve into the depth of the differences in the Linux, Mac, and Windows operating systems.
An apple computer will provide a strong possibility when purchasing a computer because of its accessibility, technology, and longevity. Mac computers come with a variety of technologies that help make accessing and operating a computer easy for everyone. They even help those with vision disabilities and those who have cognitive and learning disabilities. Programs in a Mac computer include a built-in screen reader, screen and cursor magnification, high-contrast settings, and more. Besides the programs offered to help the ones who need assistance, Mac computers use an operating system that makes navigation around the computer easier than a PC.
Two approaches to the distribution of software is open-source software, also called free and open source software (FOSS), and closed-source software. Closed-source software is when there are restrictions to the original code source of the application. The consumer cannot change the code source. They only purchase the right to use the software, not the software itself. Open-source software allows the consumer to change the product’s source code to meet their needs.
To communicate with the network, the NAS system uses TCP/IP protocol and is often managed via a web browser interface. Storage can easily be added to the NAS system without worry about network downtime. An NAS system can also be easily configured to make use Raid arrays and scheduled backups and therefore seamlessly guarantee that data is safe at all times. Storage area networks share many of the advantages offered by NAS devices. The factor that differentiates SAN and NAS is the scale through which each can be used.
7. Drivers are programs that control a device and act as a translator between the device and the operating sustem and programs that use the device. 8. Plug and play allows you to install or connect a device, and the operating system will automatically recognize, configure, and install the appropriate drivers for the device. 9.
