Linux Operating System Resembles Unix Operating. System

I propose that our company consider implementing Linux for our servers and workstations. There are many excellent reasons to employ Linux as the operating system of choice for our company: Linux is ‘tried and true’; is used by many large companies, such as Google©, Amazon©, Facebook©, and many of the cloud service providers; is less expensive; more reliable and stable; has extensive free community support; uses memory and CPU resources more efficiently; is reasonably easy and quick to install; and is much less vulnerable to viruses and malware than the Microsoft Windows© operating system. Linux can be used on almost any type or brand of computer or server, including older models. I will demonstrate that Linux is a viable and less expensive alternative to Windows and will perform well in our server and workstation environments.

There are many operating systems in use today, a few examples are Windows 95/98, Windows NT, MS-DOS, UNIX and one you may not have heard of, LINUX. The focuses of this report are the operating systems UNIX and LINUX, two very interesting and powerful systems. The first is often labeled as too confusing and unfriendly, the later is relatively unknown to the novice user, but surprisingly they are very similar in design. A short history of the two operating systems may explain why they are so similar.

When looking at an Operating System one could often say that an Operating System is a large sum made up of small separate parts. Much like how Knuth describes computer science being the “wall of mini stones”. The Operating System, or the “OS” can be defined as “software that communicates with the hardware and allows other programs to run”. (TechTerms.com, 2012) The Operating System makes use of two modes known as User Mode and Kernel Mode in order to

linux is a great example of an open source software development and free operating system,linux can be installed on many devices ranging from mobile phones to computers,mainframes and

processes. There are two different scheduling: real time and normal, for handling large data processes performance balance and sharing CPU equally in the system. In the scheduling of Kernel, each process has a priority value which ranges from 1 to 139. 1 is the highest priority level. 139 is the lowest priority level. The real time priorities range from 1 to 99 and the normal priorities range from 100 to 139. The smaller number of priority value, the priority is higher. All real time programs have a higher priority than normal programs in the system.

Linux based systems are modular Unix-like OSs build a large part of its component from 1970s and 1980s UNIX principles. They apply a monolithic kernel, commonly identified as the Linux kernel to execute process control, access to peripherals, file system management and networking tasks. Lonix OS drivers are either directly integrated with the kernel or come in as additional modules created while the system is awake. Independent developments with kernel interface improve the functionality and performance. GNU user land association with Linux based systems provides majority executions in the C library, a command-line interface (CLI) shell and the most common tools of UNIX to carry out performance execution. A GUI is created on each implementation of the X windows system. A recent development of the Linux OS is the use to Wayland display server protocol replacing the X11. Ubuntu has made progressive developments of the Mir a diversion of Wayland.

sensors, motion detectors etc.). Almost all programs require some sort of input and produces output. This involves the use of I/O operations. The operating system hides the low level hardware communication for I/O operations from the user. User only specifies device and the operation to perform, and only see that I/O has been performed (i.e. choosing one of the printer in office for printing service). For security and efficiency, user level programs cannot control I/O operations. Therefore, the operating system must facilitate these services.

The kernel is really the heart of Linux. Its job is to operate all the programs and manage the attached hardware devices. In order to put these kernels to work and operate any computer operating system,

The first version of their productive work was UNIX. Linux has many similarities with Unix. Linux is a multitasking and multi user operating system. Linux is a distributed system which means that components located on networked computers can communicate and coordinate their actions by passing messages. The components interact with each other in order to achieve a common goal.

There are different characteristics considered when making an alternative operating system that is viable for an organization. Linux is a multitasking operating system feature developed for programs and a model of Unix. It is a free open source. Linux form the background for many offices. It is easy to install application used in the organizations such as office, word and web browser applications. Linux helps in saving companies money Photoshop program is also very convenient in productivity which goes hand in hand with open office and LibreOffice (Nutt, 2004). Windows dominate operating system in the enterprise world. The Linux is compatible with many hardware options and has no licensing fee as a server of the operating system.

Assessing the differences and similarities between the components of Linux and Windows systems, a user can decide which system would best meet their needs. The architecture of the kernel and how it operates can play a factor for security and efficiency. The visual aspect and workability with the Graphical User Interface (GUI) or command interface can employ ease of use or offer streamlined productivity. Then lastly, looking at the statistical data regarding Total Cost of Ownership and general popularity by actual use and preference will be compared.

When looking into the selection of an efficient and effective, secure operating system, each aspect must be taken into consideration. Many of the international companies have developed numerous actions for handling the operations in a beneficial way. The secure operating system offers enhanced security for the information stored at each company. It also is very helpful to protect the information of the customers. The key objective is to establish a Software Network Bridge that encourages the implementation of the Linux operating system in a useful way. It is well known that being able to implement a Linux operating system there must be a lot of focus on many different features..

An operating system is an interface between the user of the computer and the computer hardware. The main purpose of the operating system is to provide user an environment where he can run the programs in the efficient manner. CPU is considered to be the heart of the system so it should be effectively used. Improper use of CPU can reduce the system’s efficiency. Hence processes are been continuously running in the CPU to make it more efficient and have maximum utilization. The topic we have chosen is enhanced round robin scheduling. There is a reason for selecting round robin scheduling as it a very fair scheduling that gives equal time quantum to all process. This is the major advantage over all other scheduling algorithms. In operating system multi-programming is a major issue. The main aim is to run several processes

File systems is a method of sorting data structure in the operating systems and means to keep track of the virtual data in the operating systems without a file system information stored would be a large body of data with no way of knowing where a piece of data is stored begins and ends. File systems is also referred to as partition or disk which is uses files or the type the file systems. A file system on a disk or partition is a way to organize, navigate, hierarchical data can be accessed, stored and retrieved in a form of folders or files. When files system is referred to as a partition it means that the hierarchy of directories also known as the directory tree. It is used to organize files on a computer system, the hierarchy of directories is locked on a single partition or disk it can also be spread over multiple disks even disks on a different computer at a different location.

Operating systems is a crucial component of the whole computer machine operating systems are used to run the computer without this the computers will be hopeless the back of he computer is where operating system is the OS of the computer is usually in Rom chip so its stored in there going back to when I said that it’s a crucial part on computer that’s because it enables your computer to have a desktop and also it enables it to run other pieces of software what are called programs so basically it manages your computers hardware and software operating system manages software by telling hardware what to do and what no to so basically without this no user would be able to communicate or interact with software programs so basically when you click on a program on your computer or browse something it automatically finds outs and sends commands to the program by this the program makes use of the CPU and the memory of your computer. By this it will communicate the output of the programs to h e user by utilizing the monitor screen. Good thing about operating system is as you as you are logged on it automatically keeps all kind of programs on your computer running so when you do click on a certain program it uploads in no less than a minute or 2. Moreover your computer must have the suitable device drivers for the software to work with the hardware and the hardware with the software. Operating system is in products like mobile phones computer laptops iPad even you’re TV. Hardware
