Collaborative Troubleshooting Operating Systems

Introduction
Working in technical support role within an IT department of a major organization requires someone with knowledge of various operating systems and ability to troubleshoot the problem methodically. A good technician can use his knowledge to accurately diagnose, pinpoint the problem, and solve the issue.

Scenario 1

You have recently started in a new technical support role within the IT department of a major manufacturing organization. Your first support call is from a client who is using Windows ME® and has encountered stability problems. Discuss the process you would undertake to identify his or her problem and the operating system’s tools that you would use to do so.

In order to determine the cause of the instability you may need to probe the client and ask questions to help pinpoint the problem. Did the user receive any error messages? Is the computer just generally running slowly? Did the client recently install additional software or hardware? If the client is unable to help answer questions then a process of troubleshooting steps may need to be taken to solve the instability issue. Start with the booting up the computer and checking for any error messages during Power-On Self-Test or POST and that maybe BIOS related. Sometimes BIOS can let you know that a piece of hardware isn’t being detected properly. You may need to enable a device or setting which can be fixed in the BIOS setup. Check your BIOS settings and see that there are no errors in the configuration. A bad configuration can cause a halt the loading process of the OS. Another type of configuration that may need to be checked if Windows fails to load correctly is the Registry. Windows ME has a built in scanreg utility which automatically makes a backup of the registry every time it is booted successfully. You can try to…...

...Operating systems What an operating system does The operating system is software, an operating system makes a computer come alive. When a computer is first built it is effectively cut-off from the world as it cannot receive input or provide output. Without an operating system a computer cannot work efficiently. The operating system has three main tasks to do:  Manage the computer resources: Input and output functions of the computer are controlled by the operating system. The operating system has to manage the CPU, how memory is allocation , access to disk drives, and many other tasks.  Interact with the user: All computers need someone to interact with it, to control it . It is the operating system's task to provide a means of doing this which is easy, consistent, flexible and structured. An operating system also allows the user of the computer to make changes as well.  Run applications: Application packages, such as word processors or spreadsheets, are what most users use on their computers, for most it is essential for their daily use of computers . The operating system provides a means of executing them, and provides the programs with tools and services. These include commands from retrieving data from a hard disk, or even to send data to a printer. LINUX The history of Linux began in 1991 with the commencement of a personal project by a student who was called Linus Torvalds. He studied at the University or Helsinki and this is where he created......

...Khajeh-Hosseini, 2009). As experienced by large or small companies while adopting cloud computing technology, the issues can be outlined as security, privacy, data migration as (Hosseini, et al., 2010 ). Adoption of cloud technology by enterprises especially those are using KBE (knowledge based engineering) systems are in risk in terms of migration their data over the cloud. Most enterprises are in a midst of creating, sharing, streaming and storing data in digital formats to allow collaboration , hence there is a need to continuously managed and protect the data to ensure its value and authenticity (Yale &ump; Chow, 2011). Enterprises now acquire increasingly more information about their products, customers and partners- whether it’s stored in a cloud environment or not and failure to protect this data can be damaging. Partners and clients anticipate their information will be constantly protected before conducting business with a company. Within lay the need for complete data governance to manage and protect crucial data, which has become a key issue for the cloud (Yale, 2011). The literature review aims to address the adoption of cloud computing within enterprises those are using KBE systems and how this adoption of cloud will affect their data governance strategies by drawing findings from different practices and other studies. The report will highlight importance of cloud computing in enterprises and address the state of cloud data governance importance within......

...Researching operating systems I am choosing Windows XP for the basic low end computer because the system requirements are fairly low and it will work on just about any personal computer that is being used today. The operating system I am choosing for the high end computer is Windows 7. Its requirements are tailor-made more for the newer and higher end computers. Some of the computers that are out there will not be able to run windows 7. Windows XP system requirements are a Pentium 233 megahertz processor, at least 64 megabytes of system memory, at least 1.5 gigabytes of hard disk space, CD-ROM or DVD drive, video adaptor, and a monitor with a screen resolution of 800x600 or higher. Windows XP doesn’t have a very memory intensive graphical user interface either. If you are upgrading from Windows 2000 you probably won’t notice too much of a difference as far as the general look and feel of the operating system. You will have to activate it soon after you install the program to keep it from deactivating. Windows XP also has better security and protection than previous versions. Windows 7 system requirements are 1 gigahertz or faster processor, 1 gigabyte of system memory for 32 bit systems and 2 gigabytes of system memory for 64 bit systems, 16 gigabytes of hard disk space for 32 bit systems and 20 gigabytes of hard disk space for 64 bit systems, support for DirectX 9 with windows display driver model 1.0 and 128 megabytes of memory for the Aero theme desktop, a......

...Operating System Introduction Operating Systems have come a long way since the times of a separate windows system and Disk Operating System (DOS). Now, both systems are combined which made DOS obsolete. According to Capron (2001), “An operating system is a set of programs that lies between applications software and computer hardware; it is the fundamental software that controls access to all other software and hardware resources” (p. 65). Operating systems have three main functions: to manage computer resources, to establish user interface and to execute and provide services for application software. The computer would just be useless machine with no direction or purpose without an operating system. According Nickerson (2001), “The most important system software is the operating system because without it computers would be extremely difficult to use” (p. 31). Operating System Compatibility in the Workplace Watts-Smith and Cheng (2004) define compatibility as, “The ability of all hardware and all software in one unit, such as a computer, to work together without difficulty” (no pg.). As with a perfect world, there is no such thing as a perfect computer or software. There will always be compatibility issues with their set of patches and service packs to assist in the smooth operation of a computer information system. In the case of operating systems, upgrades always bring their host of compatibility problems or issues. While most compatibility issues go relatively......

...DENIS In a multiprogramming and time-sharing environment, several users share the system simultaneously. This situation can result in various security problems. What are two such problems? A time sharing environment or multi programming is one in which a computer system provides direct communication between the user and the system. It allows many users to share the computer at the same time. One of the problems that may result from the fact that resources are being shared is information theft, this is because all the users are able to access the files that are being shared on the system and so one can easily copy a file and modify it without the knowledge of all the other parties. Such scenarios can result into loss of security confidentiality and integrity since the owner of a file Without being aware of the system used as time-sharing and multiprogramming, may insert or have a secret or confidential data that he wants to remain at the file and also other users may change, add, or even remove some information in the file if they want to, since they have access to all files running on the system The other problem resulting from using such systems is the fact that there could be loss of storage space. Since users have equal privileges to create and access files on the system, then there could be a possibility that the users will create numerous files and eat up the storage space on the system without the other users’ knowledge, so as time goes by, each user will......

...Operating Systems Christy Kegley IT/282 3/2/2014 Carlton Foster Operating Systems * Provide a brief history of three operating systems. The top three operating systems are; Windows XP, Windows Vista, and Linux. “Windows XP is the first Windows OS to allow multiple users to log on simultaneously to the OS, each with their own applications open. Although Windows XP was first released with some bugs, the second service pack (Service Pack 2) resolved most of these problems. XP underwent three service packs. It is an extremely stable OS and was popular in both the home and corporate markets” (Guide to Managing and Maintaining Your PC, Eighth Edition, Andrews, pg. 1116). This programs allows users to do many things that others might not allow like older versions of Windows. Windows Vista is the newest version of Windows. This program is not very popular with some people because there is a lack of compatibility with other programs, also it slows performance. “The first problem is partly caused by hardware manufacturers not providing Vista drivers for their devices that were originally sold with XP drivers. The second problem means that many low end desktop and laptop computers can’t run Vista. And the slow performance of Vista is partly due to the many unnecessary features (fluff) it offers; these features weigh heavy on system resources. Vista comes in five versions: Windows Vista Home Basic, Home Premium, Business, Enterprise, and Ultimate. (Vista......

A security flaw according to "Apple Security Flaw: What You Need To Know" (2014), "The flaw is in the way the operating system provides the essential services, known as secure sockets layer (SSL) or transport layer security (TLS). These two layers of security allow information to be transmitted worry-free between browsers and web servers, or between a mail server and mail client. SSL is in the form of encryption, which scrambles data sent over a network to keep it private. The second layer involves verification that the server is authentic." With the heighten computer security regarding vulnerabilities, the increase of user awareness and training users to not click on particular links is difficult yet feasible. Although most operating system has computer security protection, the tasks of protecting the systems from vulnerabilities are a daunting task because the operating systems are unique.

...NT1110_StudentName_Module1_Lab.doc 3/21/15 An operating system takes input in the form of zeros and ones -- bits -- and runs them through various circuits and processors, the hardware behaves according to built in rules. We define these rules using gates, which take input and produce an output in a structured way. The operating system allows complex programs to access hardware to get results. Only the hardware's physical properties can limit what programs can do. You could design an operating system by physically programming it into a computer's circuits. This would require building electrical pathways using millions of gates. But such an operating system would be slow and you would need the patience of Jonah to use it. That's why operating systems like Mac OS X and Windows are software. Software is flexible and hardware is not -- you can make changes to software with updates. To do the same with hardware would mean switching out physical chips and circuit boards. Operating systems are like the manager for a computer, it’s the job of the OS to monitor what software needs and what the hardware can provide. When you run applications on your computer, the OS allocates the resources necessary to complete the task. That can include processing power, memory and computer storage access, among other things. Ideally the OS will make sure that your computer's hardware is never overtaxed. ...

Troubleshooting and Maintenance Issues for Operating Systems

...Troubleshooting and Maintenance Issues for Operating Systems Troubleshooting an OS for either a personal computer or workplace, can be a lengthy and multifaceted process, if one does not know what they are doing. However, with certain logical and systematic steps, this can be simpler task for even the novice of users. Since there are many different problems that can occur with an OS, there is not one type of step that can be done, but often with a simple process of elimination, the problem can be solved. With newer users and tech, a though process is often needed, yet with a more knowledgeable technician, they have the benefit of experience. More often than not, maintenance can be the cause of such problems, which is why an emphasis on preventive maintenance is advised. Preventative maintenance is paramount in PC functionality, yet it the most overlooks aspect of PC care. When conducting maintenance of a PC, one can help save costly fixes in the future, as well as safeguarding your information saved on your PC. Troubleshooting techniques for operating-system-related problems There are basically two different types of ways one can determine what needs to be fixed with an operating system: Trial and-error and systematic troubleshooting. “Trial-and-error troubleshooting is based on the idea that you have a problem and do not have enough information to give you a viable starting point. The trial-and-error method is a great for attempting to solve......

Context Switching It is the process of storing of storing and restoring the state (context) of a process or thread so that the execution can be resumed from the same point at a later time. There are three potential triggers for a context switch: • Multitasking: Most commonly, within some scheduling scheme, one process needs to be switched out of the CPU so another process can run.This context switch can be triggered by the process making itself unrunnable, such as by waiting for an I/O or synchronization operation to complete. On a pre-emptive multitasking system, the scheduler may also switch out processes from being starved of CPU time, preemptive schedulers often configure a timer interrupt to fire when a process exceeds its time slice.This interrupt ensures that the scheduler will gain control to perform a context switch. • Interrupt Handling Modern architectures are interrupt driven.This means that if the CPU requests data from a disk, for example, it does not need to busy-wait until the read is over, it can issue the request and continue with some other execution. When the read is over, the CPU can be interrupted and presented with the read. For interrupts, a program called an interrupt handler that handles the interrupt from the disk. When an interrupt...

Troubleshooting Operating Systems Arron CIS/296 Febuary 15, 2016 Steven Kernan Troubleshooting Operating Systems I have recently started in a new technical support role within the IT department of a major manufacturing organization. I am going to go through two scenarios in which I will help callers with problems occurring while using Windows XP and Windows Vista. The organization I am a part of doesn’t have a standard operating system in use. There are numerous products and versions in use across the whole company. I am going to discuss which of the operating systems I would recommend that the company makes standard between Windows XP and Windows Vista. I will also make a recommendation of which of the operating systems I would replace if I was in charge of the organization. My first scenario is that I receive a call from a user that using a Windows XP operating system and has encountered stability problems. The first thing I am going to do in order to gain more knowledge of the problem at hand is investigate the situation. I need this knowledge so I can properly troubleshoot the problem the user is having with the operating system they are using. The second thing I will do is establish a theory from the information I got from interviewing the user then I will test my theory. If my theory isn’t accurate then I will rethink the problem and figure out what occurring symptoms could be caused by, if my theory is correct I will resolve the problem. Taking preventative......

Everybody knows what is a Hard Disk or Hard Drive let me refresh your mind, with a simple explanation: Hard Disk/ Drive, is a device for storing and retrieving digital information, primarily computer data. It consists of one or more rigid rapidly rotating discs (platters) coated with magnetic material, and with magnetic heads arranged to write data to the surfaces and read it from them. With that been said, now move forward with Operating System and Hard Disk/ Drive. I would like to recommend you the best operating system is DOS (Disk Operating System), why? Because has everything you need. Let me tell you a little more about DOS. Disk Operating System: Most often abbreviated as DOS, refer to operating system software used in most computers that provides the abstraction and management of secondary storage devices and the information on them (e.g., file systems for organizing files of all sorts). Such software is referred to as a disk operating system when the storage devices it manages are made of rotating platters, such as floppy disks or hard disks. In the early days of microcomputers, computer memory space was often limited, so the disk operating system was an extension of the operating system. This component was only loaded if needed. Otherwise, disk access......
