“UNIX was the first operating system designed to run on ‘dissimilar’ computers by converting most hardware specific commands in machine language into an independent programming language called ‘C ’” . UNIX was the basis of AT&T’s telephone system and the government’s wide area network system. Then it became the basis of communication between engineers and scientists, and eventually the basis of communication for everyone worldwide. It has held this remarkable spot since 1969. However, in the 1990s
different operating system. History of UNIX UNIX was first started off as a study development which gets involved with a few cooperative enterprises between Bell Laboratories, General Electric and MIT in 1969. Subsequently after the withdrawal of Bell Laboratories in 1969, Ken Thompson and Dennis Ritchie still hold on to the project they have built. Some claim that they required the operating system to maintain their favorite pc games. Over the past UNIX continue to develop in becoming one of the
An Overview of UNIX Security The purpose of this paper is to analyze the security of UNIX. Considerations shall be given regarding generalized security aspects of a typical UNIX system. The ultimate scope of the following presentation shall remain within the boundaries of a few of the more critical UNIX security aspects. Of particular note will be discussion regarding standard user access, root access, file system security, and internet access precautions. This will not focus on specific measures
History of Unix This document is designed to give people with no previous UNIX experience some sense of what UNIX is. This document will cover the history of UNIX and an introduction to UNIX. HISTORY OF UNIX AND CAUSES FOR ITS POPULARITY Most discussions of UNIX begin with the history of UNIX without explaining why the history of UNIX is important to understanding UNIX. The remainder of this document will describe some strengths and weaknesses of UNIX and attempt to explain why UNIX is becoming
The uniqueness of UNIX The features that made UNIX a hit from the start are: Multitasking capability Multi-user capability Portability UNIX programs Library of application software Security 1. Multitasking Capability Many computers do just one thing at a time, as anyone who uses a PC or laptop can attest. Try logging onto your company's network while opening your browser while opening a word processing program. Chances are the processor will freeze for a few seconds while it
UNIX VS NT To build a good and stable network is extremely difficult. It takes a team of very knowledgeable engineers to put together a system that will provide the best service and will forfill the need for the companies users and clients. There are many issues that have to be resolved and many choices have to be made. The toughest choices IT managers have to make, are what will be the best server platform for their environment. Many questions must be answered. Which server software offers complete
Comparing Microsoft DOS with UNIX As is suggestive of its name, an operating system (OS) is a collection of programs that operate the personal computer (PC). Its primary purpose is to support programs that actually do the work one is interested in, and to allow competing programs to share the resources of the computer. However, the OS also controls the inner workings of the computer, acting as a traffic manager which controls the flow of data through the system and initiates the starting and stopping
For UNIX truly to be an open system, The Open Group provides certification and standardization for UNIX-like operating system, thus regardless of different UNIX-like environment the standards set by The Open Group are the same, therefore it helps eliminate confusion and achieve consensus among the various interests of the members of the standards-forming bodies. Several standards have come about as the direct result of computer users’ desire to see UNIX standardized and to see it evolve in a direction
If you're a techie entrepreneur creating a big e-commerce site, you may decide to buy a high-end Unix box to accommodate the volume and processing demands your bean-counters have projected for you. You'd run Sun Microsystem's Solaris software on it to power your Web server and e-commerce applications. Or, you could opt to save a little venture capital and run Linus Torvalds' free operating system (and its accompanying free server apps) on a cluster of commodity Intel PCs. The Linux OS is well-suited
Linux and the major versions of Unix are similar, code developed on one platform usually can be ported to another. They also can use the same tools, such as the GNU tools from the Free Software Foundation. ("Geeks") The GNU/Linux operating system will likely continue to grow in popularity throughout the decade initially with hackers and then with consumers. Works Cited Moody, Glen. Rebel Code.

beginnings in 1991(Torvalds & Diamond IX). For better understanding one must pay attention to how the computing community was at the time when Linux was being developed. Unix had been quite popular for many years but following the AT&T split it began to be sold by licensing companies (Negus 10). One issue was that the price for Unix was based off of large mainframes instead of individual personal computers (Negus 11). Linux began with the need for a
Have you ever taking into consideration what type of world we live in right now? It is a cyber world full of great expansions, opportunities, innovative ideas, and technology. All most everyone has heard of Bill Gates, Steve Jobs, Steve Wozniak, alongside with Ben Ive. But does anyone hear of the people behind the scenes, or give any credit to them? Top programmers around the world such as Dennis Ritchie, Ken Thompson, Bjarne Stroustrup, and Tim Berners-Lee develop important things that are needed
The 1960’s: Decade of Change There is many decades that people would call the Decade of change but the 1960’s is the decade that changed the most. The 60’s was a very crazy and wild time because of the historical events that happened. Everyone was starting to experiment with LSD and Other kinds of drugs. There was also a huge surge of musical history that had happened in the 60’s that changed the History of music forever. The 60’s is what I like to call the best decade in history. The 60’s is the
language upon the modern technologies. To speak about c programming language, Dennis M. Ritchie must be mentioned. Dennis MacAlistair Ritchie was an American computer scientist who helped shaping the digital era. He created the C programming language and Unix operating system with his colleague Ken Thompson. (Geoff, 2011) In the late 1960s, after earning a degree in physics and applied mathematics from Harvard, Ritchie started his career at Bell Labs (AT&T), which was one of the centers of technology development
Linux Networking Capabilities Linux is a Unix clone written from scratch by Linus Torvalds with assistance from a loosely-knit team of hackers across the Net. It aims towards POSIX compliance. It has all the features expected in a modern fully-fledged Unix, including true multitasking, virtual memory, shared libraries, demand loading, shared copy-on-write executables, proper memory management and TCP/IP networking. It runs mainly on 386/486/586-based PCs, using the hardware facilities of the
will trace the history and usage of this still popular and widely used protocol and explain where and how it still manages to fit in today. HISTORY AND FUTURE OF TELNET "Telnet" is the accepted name of the Internet protocol and the command name on UNIX systems for a type of terminal emulation program which allows users to log into remote computer networks, whether the network being targeted for login is physically in the next room or halfway around the globe. A common program feature is the ability
Linus Benedicts Torvalds. The operation system is the key of communication between the software and the hardware. Linux is a free and open-source software1 built around the Linux kernel. The first event leading to its creation is the conception of the UNIX operating system implemented by Ken Thomson and Dennis Ritchie in 1969 and first released in 1970. They rewrote it to make it portable and it became widely adopted, copied and modified by academic institutions and businesses. In 1987, Andrew Tanenbaum
The creation of this assignment is to create a baseline knowledge and explain my journey of becoming a Linux administrator. In this assignment, I will continue to cover the topics that I had learned and discussed in the third and fourth weeks of class after the first assignment. After learning the foundations of the Linux Operating System, It is now time to peel back some layers and go more in depth with this intriguing O.S. The discussions topics that will be touch upon is the Boot Process and
Maintenance Management Systems Introduction In recent years organisations have come to recognise the value of developing a system that can operate as a maintenance and performance improvement tool. Such tools are known as Maintenance Management Systems (MMS) and are used to control planned maintenance carried out across plant and facilities. MMS assure that assets (i.e. production equipment) are properly maintained and operating within specifications. These systems also help to prevent breakdowns
A comfort zone is securing people in a place where they feel themselves safely away from circumstances in life. The individuals can feel safe when they want, but they are damaging themselves in certain ways. They would adapt to a comfort life and it will make it difficult for them to overcome the comfort zone. This is a major problem for society because it prevents them from accomplishing goals like make important business decisions, socialize with people, self-development, etc. All the elements
