Linux was created by Linux Torvaldas in 1991. Linux is a free and open source software operating system for computers. The operating system is a collection of the basic instructions that tell the electronic parts of the computer what to do and how to work. Linux is a Free and open source software (FOSS) means that everyone has the freedom to use it and modify it. Some features of Linux are:
• A fully networked 32/64 bit Unix like OS
It have Unix tools like sed, awd and grep
It have compilers like C, C++, Fortran, smaltalk, Ada
It includes network tools like telnet, FTP, ping
• It allows multi-users, multi tasking, multi processor
• It coexists with other OS
• It includes source code
Separate projects that interface with the kernel provide

Most popular user interfaces are based on the X Window System, often simply called "X". It provides network transparency and permits a graphical application running on one system to be displayed on another where a user may interact with the application.
3.1.1 Advantages of Linux
• Low cost: There is no need to spend time and huge amount money to obtain licenses since Linux and much of its software come with the GNU General Public License. There is no need to worry about any software's that you use in Linux.
• Stability: Linux has high stability compared with other operating systems. There is no need to reboot the Linux system to maintain performance levels. Rarely it freezes up or slow down. It has a continuous up-times of hundreds of days or more.
• Performance: Linux provides high performance on various networks. It has the ability to handle large numbers of users

• Multitasking: Linux is a multitasking operating system. It can handle many things at the same time.
• Security: Linux is one of the most secure operating systems. File ownership and permissions make Linux more secure.
• Open source: Linux is an Open source operating systems. You can easily get the source code for Linux and edit it to develop your personal operating system.
3.2 OS DUMPING
3.2.1. System Setup and Configurations
3.2.1.1 Boot Options
• Select the booting mode by toggling the switch S2.
• When toggling the S2 switch to the “NOR Flash” side the system will boot from on board NOR Flash. When toggling the S2 switch to the “NAND Flash” side the system will boot from on board NAND Flash.
3.2.1.2 Connecting Peripherals
• Connect the MINI2440 board’s serial port to a PC’s serial port.
• Connect the 5V power supply adapter to the 5V power supply interface on the board.
• Connect an LCD touch panel (if the user has one) to the LCD interface on the board following the data bus’ arrow.
• Connect the MINI2440 board to a PC with a USB cable.
3.2.1.3 Setting up Hyper
For example, when we run Nginx on all six kernels, the performance of it running on other kernels ranges from 91\% to 97\% of the performance on its own kernel. On the other hand, although the performance of Memcached is generally good while running on other kernels, the performance of other applications running on the Memcached kernel could be as low as 93\% of their best performance. The results show that we have created emph{truly} application-specific Linux kernels for
Perhaps many are confused about the existing commands linux, this time I will discuss about the linux basic commands used along with examples of its use. 1: Seeing identification (id and group id number) $ Id 2: Looking the calendar date of the system a. Looking at the current date $ Date b. See calendar $ Cal 9 2002 $ Cal -y 3: Seeing the machine identity $ Hostname
The process of starting a kernel is different between the Linux kernel and Android kernel. Figure 2.3 illustrates the processes of booting Android and Linux operating systems. Both processes have six steps that are similar but do have significant differences that are discussed in this section. Figure2.3 Android and Linux kernel boot processes

So if separation of mechanism and policy happen then It will be very flexible while performing operations in different conditions 6. Explain the tradeoffs made in choosing between a simple, monolithic operating system approach versus a microkernel approach. Answer: 1. Monolithic Kernel: All Kernel Services From single component means as a
I have been asked to use Ubuntu? One comparison between windows and linux is that Linux is a lot freer than windows because windows are restricted. Another comparison is windows are a lot safer because if something breaks you get paid support whereas on Linux you do not have any support. My experience with Linux is not much as I am entirely a windows user.
Task1 (3) - comparison of three operating system Components Window 7 Window 8 Ubunutu 12.04 Security It has better firewall. It also support bit locker drive encryption, which encrypt window hard disk to keep documents and passwords as well. Also help to protect desktop against viruses and other malware with Microsoft security essential. It also supports parent’s control which is also an essential part.
Network Monitoring Management I definitely feel that Linux and Windows machines provide very different sets of traits that work better for different things. Linux is clearly the more easily secured server as it allows a lot more granular control of every piece of the operating system and the data that is housed there. Also, being completely open source, it allows for a lot more options for software as well as control over every aspect of the system. Windows, on the other hand, has what I feel is a lot more developed approach to managing users, groups, and machines.
2) at the beginning of the computers industry the user was dealing with text interface only and every thing
Information in the RAM can be read and written quickly in any order. Usually the RAM is emptied every time the computer is turned off. It is known as 'volatile memory'. 1.8.2 ROM (Read-Only Memory) ROM is a memory chip where crucial system instructions (BIOS) are permanently stored. The data held on ROM can be read but not changed.
There are many operating systems but I am not listing all of them. One operating system is Windows, made by Microsoft. Another operating system is Mac, made by Apple. And one operating system you most likely don 't know is Linux, Linux is an open source operating system and it is the fastest, tho you probably don 't and will never use it. An open-source operating system is an operating system that you can edit like Windows is not an open source operating system so you can’t edit it, but in Linux, you can edit its operating system.
We need to administer a substantial number of systems, centralized system management tools such as the Red Hat Network, Canonicals’ Landscape, and Novell’s ZENworks
1. The operating system I am using is windows 7 and it allows me access Word, Excel, Access and PowerPoint. 2. A user interface is the way in which the user will interact with the computer system and all the apps that are available on the computers software. The components of a user interface is navigation mechanism, input mechanism, and output mechanism.
Management can be defined as getting the maximum efficiency and effectiveness out of a set of activities. A manager carries out this process. My chosen company for this project is Microsoft.
Opportunities • Highly scalable model that gives the opportunity to grow across different countries. • Large market that is continuously growing. • Potential increase in-market and out-of-market M&A. • Venture capital available.
