- Linux is so popular because it’s free, you can make any changes to it for the most part hassle free, it a very advanced (sometimes more) and usually better than software you pay for. Academia likes it so much because of the reasons I stated above and plus when it was first introduced in 1975 it was such an advanced developing system. Q3. – Systems that you can run multiple machines/users on, i.e. VMware.
Homework Assignment 1.1 Provide brief but complete answers to the following questions. Q1: What did Richard Stallman mean when he stated that GNU was a free operating system? A1: Stallman’s original manifesto stated, “… I am writing so that I can give it away free to everyone who can use it.” He later amended this because of a perceived confusion over the meaning of “Free” to say that “… nobody would have to pay for *permission* to use the GNU system”. Basically, Stallman wanted individual to have the right to use, distribute, and modify GNU unencumbered; while allowing business to charge for distribution and support if they choose to do so. This is how we’ve come to view Open Source today.
Comparison chart | Linux * | Windows * | What is it? | Linux is an example of Open Source software development and Free Operating System (OS). | Windows is the family of operating system (OS) from Microsoft, which is the most famous OS in the world. | Cost: | Linux can be freely distributed, downloaded freely, distributed through magazines, Books etc. There are priced versions for Linux also, but they are normally cheaper than Windows.
In order to install a virus on to a Linux system the application needs to gain administrator (root rights). Many companies are even use Linux as their firewall system. “A standard tactic on many networks is to employ a secure Linux box as a firewall, intercepting intruders before they hit the network, and Security Enhanced Linux (SeLinux), developed by the US National Security Administration (NSA), is a component of many Linux systems.” (Hillesley, 2009). Quality and Support is the third criteria. Many people in businesses believe, because something is for free the product has a pure quality or bad to no support.
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.
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?
1. What did Richard Stallman mean when he stated that GNU was a free operating system? What Richard Stallman meant by stating that GNU was a free operating system is that it was a free software that users had the freedom to distribute and change the product. 2. Describe the relationship between Linux and the GNU Project.
contractors. TSI makes embedded operating systems for secure terminals that control ingress/egress control systems for Wall Street firms, camera systems for drone aircraft for government contractors, and alarm systems for top-secret government installations. TSI operating systems are worldrenowned for their quick response to sensor input, highly reliable operation, limited memory utilization, small size on disk, and low power consumption. The TSI Operating System (TSI OS) works exceptionally well on the devices owned by TSI customers, but it does not work well in the TSI back office. Like many startup companies, TSI had to cut costs when it launched a few years ago.
* When it comes to large USB flash drives, the FAT32 file system is the intended primarily used. The reason that FAT is used is because FAT can be used on both operating systems, Windows and iOS, and NFTS cannot be used on non-window systems. * Which file system provides support for larger hard drives and better security in the form of encryption and permissions that restrict access by unauthorized users? NFTS is the required file system for large hard drives, because you are able to give it better security than the FAT. With FAT and if you are using Windows 7 then your files can be read unlike the NTFS.
Christian little UNIT 7 LABS NT1210 4/27/2014 LAB 7.1 Exercise 7.1.1: Owning the entirety of a WAN is impractical for an organization because there are no limitations and they can be custom built to the organization. It is favorable for the organization to maintain a LAN for expansion purposes. Exercise 7.1.2: On a WAN there is no absolute limit for the distance of a leased line. Table 7-1 WAN Physical Media Media | Infrastructure | Summary | UTP | Phone lines | Uses copper lines between all locations, limited speed with the lines. Already in place, can be very cheap to use | Coaxial | Television cable | Must run cable to all locations, can carry much higher speeds than Telco.
