★ Linux is an open source operating system based on UNIX. ★ The GNU is a completely free (in the freedom of speech sense) operating system built by Richard Stallman. ★ Linus Torvalds wrote the kernel for Linux, which was also intended to be a free kernel and added features supplied by GNU. ★ Linux was born off the internet with hundreds of people helping to develop it in its early years In which language is Linux written? What does the language have to do with the success of Linux?
B. Cannot restrict people from modifying/using/redistributing the software. C. Users must be allowed to redistribute modified versions under the same terms/licensing. 2. Linux is portable, is based on standards, is written in C, has a kernel programming interface, can support many users, and can run multiple tasks simultaneously.
Some users may obtain copies at no charge, while others pay to obtain copies and if the funds help support improving the software much better. The important thing is that everyone who has a copy has the liberty to work together with others in using it. The three principle qualities of free programming are: The source code must be taken with the project, you can't bound individuals from redistributing/fluctuating/exploiting the product, and clients must be permitted to redistribute changed forms under the same norms/authorizing. 2. Why is Linux popular?
Which parts of the Linux operating system did each provide? Who else has helped build and refine this operating system? The (FSF) is a 501 non-profit organization founded by Richard Stallman on 4 October 1985 to support the free software movement, which promotes the universal freedom to create, distribute and modify computer software, with the organization's preference for software being distributed under copy left. Linux is an open-source operating system modeled on UNIX. Thousands of people helped refine the operating system online and freely.
There are no disruptions to the network when connecting or removing devices and it is easy to detect faults and remove parts. Whereas some disadvantages are that is requires more cable length than a linear topology. If the hub fails the nodes attached are disables and it’s more expensive than a linear topology. A bus network topology is a network architecture in which a set of clients are connected via a shared communications line/cables” (Abu, 2013). There are several common instances of the bus architecture, including one in the motherboard of most computers.
The data signals travel around the look in one direction which passes through each computer. This allows the signal to be boosted each time it reaches a computer. This is also known as token passing from computer to computer. You don’t need a central server to manage the topology. It also handles the load better than a bus does.
This allows the multiple hard drives to work together as one larger storage device. The data is replicated on to all of the drives installed so in case one fails the data isn’t lost this is called fault tolerance. When you purchase your NAS device it comes with management software. There is also many other additional types of software available on the market for NAS devices. This software is used to manage your devices space allocation, manage and configure RAID, control storage behaviors, and perform routine maintenance.
Linux OS is a derivative of the Unix OS. The Linux OS gain momentum through its progressive licensing which allow others to increase development with the OS. With overwhelming popularity from the creation of Linux OS, Unix OS reintroduce itself again. The functionality of both UNIX and Linux is very similar by both systems able to multitask, both systems are able to run on a variety of hardware platforms, and both are capable to use a command line. Linux is different through user friendly OS and by GUI.
Unit 1, assignment 1, Chapter 1, 2,3,11 NT1430 Troy Jones; David McKee 06/18/14 Chapter 1 Exercises 1, 4 1. Free means open source” Free to down load”; Characteristics are: * Right to copy * Able to modify * Able to redistribute the source code covered by the agreement. 1. GNU is the general public license. When you redistribute the code however, you must also distribute the same license with the code, thereby making the code and the license inseparable.
Unit 1 Lab Screenshots Unit 1 Chapter Exercises Chapter 1 Exercises 1, 4: 1: Free software is un-modified software that is 100% free. Also known as freeware. 4: The foundation of GNU is to allow all people to copy, develop, distribute and modify software. Linux is a free open source OS which is all free and can be downloaded off the web. Linus Torvalds has helped build and refine Linux in 1991, along with many of his friends.
