Discussion :

Topic: Computerized Operating Systems (OS) are almost everywhere. We encounter them when we use out laptop or desktop computer. We use them when we use our phone or tablet. Find articles that describes the different types of operating systems (Linux, Unix, Android, ROS, z/OS, z/VM, z/VSE, etc). Do not select MS WINDOWS. Write a scholarly review of comparing any two or more OS; attach a copy of the article to your postings. Remember, this assignment is to be scholarly; it is not enough for you to simply post your article and add cursory reviews. Cited references are required. In addition you must read the postings of the other students and comment significantly on those areas. Please see Discussion Forum of the class syllabus for additional details on content.

The primary goal for the discussion forum assignment is to simulate the free sharing of ideas among peers that is typically experienced in graduate courses delivered in the more traditional, face-to-face environment. Evaluating a student’s performance on the assignment is not, therefore, very concrete. There are a number of factors that impact the quality of a student’s participation. The content of the contributions is, of course, one rather obvious factor, but the context in which the contributions have been made is equally important. In evaluating performance on this assignment, the following factors will be considered: Add value to the content of the discussion by posting well-written, on-topic contributions.Share resources with others by providing support for you contributions in the form of citations from the literature. Promote peer-to-peer discourse by:Initiating at least 2 quality major topics of discussion and actively participating throughout the period of the forum with at least 3 quality engagement postings responses to follow student’s major topics of discussion thread – responding to postings of others in a timely manner (within 72 hours). Each contribution (treads and replies) is expected to be though provoking and critical (i.e. “While a database is sometimes consider to consist of a large single site repository, researchers have suggested…” and not simplistic (i.e. “Yes, I agree” or “Thanks for …”). Please see class syllabus for specific grading details.

n this paper, we will discuss about Linux and UNIX. UNIX is an OS operating system usually used in several internet servers, PCs and workstations by Intel, Solaris, HP,etc. UNIX was designed with several programmers and was destined to be used for implementing software that would run several platforms. UNIX was intended to be ‘portable, multi-user and multi-tasking in a time-sharing configuration.’While Linux is a kernel. A kernel is the major component of several OS. The Linux kernel was released on 5 October 1991 through Torvalds. However, the word Linux refers to the full-fledged OS operating systems assembled with the Linux kernel. These ought to be correctly recognized as Linux operating systems or distributions. Some of the current Linux spreadings include Fedora, Ubuntu, Debian and SuSE (Forrest, Hofmeyr, Somayaji, & Longstaff, 2002).

Comparison

· Linux is implemented by open source development,i.e., by collaboration and sharing of code and several features through forums also it is distributed through several vendors. While UNIX systems are separated into several other flavors, developed through AT&T.

· Linux is open-source and free, while the original UNIX is not free for users.

· Linux is a copy of the UNIX, but it does notconsist its code.

· Linus is the kernel, whereas is a whole operating system.

· Linux was established for PCs personal computers, whereasUNIX was mainly for servers and large workstations.

· Nowadays, Linux supports more platforms and file systemsas compared toUNIX.

· In Linux, threat and risk detection and resolution are rapid, because Linux is primarily community determined while in the case of UNIX, operators have to wait, to get the appropriate bug fixing spot.

· Linux operating system is portable also can be executed in diverse hard drives while UNIX is not portable like Linux. So, these are the differences in Linux and UNIX.

· Linux support GUI while UNIX support CLI (Godfrey & Tu, 2002).

Topic: We all had the unfortunate experience of seeing how computers can, at times, make life’s journey abit more difficult. This is especially true in knowledge centric workplaces. Describe an example of a very poorly implemented database that you’ve encountered (or read about) that illustrates the potential for really messing things up. Include, in your description, an analysis of what might have caused the problems and potential solutions to them. Be sure to provide supporting evidence, with citations from the literature. As with the first discussion topic, it is not enough for you to simply create a own posting. You must read the postings of the other members of the class and comment on each of them. Please see Discussion Forum of the class syllabus for additional details on content.

The most settled oversight that I have experienced in databases is not any more the utilization of the primary key suitably. Engineers commit the error of the utilization of programming program measurements for the basic key, or figurings and links. Rather, it should ordinarily be consecutively or arbitrarily produced keys by method for the database. It is framework esteems that can empower things like cross insights to one another machine or to substitute the fundamental information, aside from irritating any hidden connections. Another arrangement of standard oversights is with respect to normalizing the information. Either developer flips the aggregate component into connections or neglects to transform it into connections when required.

A middle floor wishes to be come to. In the event that the certainties will data will be shared all through more prominent than one lines and a change would affect different columns, it should be moved to some extraordinary table. On the diverse hand, if the data will be shared amid lovely a couple of columns and an other in one won’t affect distinctive lines, it should be at the indistinguishable table. Additionally, if the records can be refreshed or utilized independently from a definitive line, it ought to be put into a different table. This additionally gives data honesty. Put away procedures may furthermore be utilized, in any case, in a few situations, manufacturers will in general abuse it. They are in truth difficult to keep up. The troublesome stage is that, as a rule, there is no reliable method to review and choose out which highlights are the use of which spared methodology. So most manufacturers wind up growing new put away strategies, as a substitute than altering current ones.

Now and again engineers, as option than the utilization of most vital keys, they are a piece of tables the use of 4 or 5 sections with the exception of handle the records totally. They expect that in each and every situation, through method for turning into an individual from these 4 or five sections, they would get extraordinary columns. However, underway, they come all through unquestionably new data where this is never again giving uncommon columns. This reasons an exceptionally root issue, and they endeavor to veils it through the use of put away techniques and other bandage settles in the front end.

The framework is an “open standard,” suggesting that an entire system of architects can alter the item, not just Google. Android comes pre-presented on mobile phones and tablet PCs for which it was plot. As of the date of creation, every one of the four significant mobile phone bearers have Android contraptions available. An arrangement of creators in like manner makes Android-immaculate devices. One of the essential focal points of the framework’s open source status is that creators can make different types of its crucial activities, allowing customers more noticeable chance to modify their PDAs.
