As a computer administrator one must be aware of what the system requirements are for the operating system being used or installed on a system. Computer administrators that install operating systems on new or old hardware often will research what the manufacturer suggests for the operating system to work properly. The requirements for an operating system can be broken down into two categories hardware requirements and software requirements.
Hardware Requirements are the resources that are needed to support an operating system. Microsoft has a set of suggested requirements and minimum requirements available to view on their web page. Direct X version 9 is a requirement for Windows 7 and is an example of a software requirement as well

Upgrading an Intel 80486 or i486 to Windows 7 is not possible for several reasons. The fastest processor for an i486, the Am5x861 was introduced in 1995 and had a processing speed of 133 MHz this is below the minimum requirement for Widows 7 which requires at least 1,000 MHz or 1GHZ of processor speed. I486 hardware also does not support enough RAM (random access memory). I have an i486 and the motherboard only accepts 160 MB of ram. The RAM requirement for Windows 7 is 1GB for 32 bit systems and 2 GB for 64 bit systems2. Video Hardware produced for an I486 is not supported by Direct X version 9. When Windows starts an install it will check to see if the hardware meets the new operating system’s requirements. These checks sometimes can be bypassed by using a system image for the operating system install. The computer still will have problems using the operating system if it does not have the proper hardware that is needed to run the …show more content…
The system image will contain a set of software that is common to computers used on the network. Using one of these images the operating system can be installed to a hard drive unattended by copying the files to the drive. The startup process3 of a modern computer requires several steps. A power on self test (POST) is used to test the system before programs are loaded. The POST will test memory, video, fixed disks and CPU (central processing unit) for compatibility and to see if they function properly. Programs are started from ROM (read only memory) stored on the computer’s main board. The BIOS (basic input / output system) loads into the system’s memory and will access programs on disk drives or fixed disks. The operating system will be loaded from a disk drive or solid state drive using the Windows boot manager.
The Operating system will continue the startup process with the Windows boot loader during a normal startup. As the operating system starts programs will start in a specific order. This is determined by the writers of the operating system. Services and programs start as each one is intended unless problems are detected by the operating system’s programming. After the Kernel and all other startup programs are loaded a logon phase is
...hes should be every three years and software updates fall in line with vendor roadmaps, the reality is actually defined by organizational pace, business needs and, ultimately, budget time is running out for this operating system as there have been tremendous problems resulting from using them. Such issues has call for research to reveals the benefit of upgrading from window Xp and windows 7 to adopt windows 8.in this paper I am going to outline the methods and procedures of upgrading from windows XP and windows 7 successfully to windows 8. Therefore, as it has been seen above, Window migration could be the better option.
It also If your Bios ever needs to be updated the first thing you should do is check with your PC manufacture’s website and see if they have the latest bios for your particular PC. When doing this also make sure you download the right BIOS for your PC model and download the exe file and install it. On older PC’s updating your bios may require you to do it differently such as having to put it on a CD and boot from it to install the latest update. Usually a BIOS update can help your computer run more smoothly and fix a lot of problems that you may have ran into in the past such as compatibility issues with software and your PC’s boot speed. Lots of the times when you get a new PC you might need to update your bios because it they usually come with a lot of bugs that need to be patched. On Mac computers they do not have a traditional Bios like a windows one may have, instead they have a boot firmware that like to call “Open Firmware”. Just like BIOS, Open Firmware also is accessible on the initial startup of the mac and it also provides you were the options for technical diagnostics and the ability to debug your computer. In order for you to access Open Firmware on your mac you when you first start it up you should hold down “option,” “command,” “0” and
Well, Before anything else, here is a few names of components that need to be known to not be completely lost. The CPU(Central Processing Unit) (It processes everything from basic instructions to complex functions.) (Techterms.com). The Hard drive (the location of all the computer’s folders, files, and information, saved magnetically so even if turned off it’ll all stay saved). The RAM (Random Access Memory) (The more RAM your computer has, the more data can be loaded from the hard drive into the RAM, which can effectively speed up your computer.)(Techterms.com), The OS (Operating System) (just what it sounds like, this is the system that works the computer, as in Windows, Linux, and Apple OS.) The Graphics card (helps the CPU by processing the graphics portion of what the CPU has to process). The Disk Drive( this is the CD,DVD, or Blu-Ray driver that is installed to use CD’s DVD’s and or Blu-Ray disks.) The last major term to know is the Motherboard ...
Someone who is working as a Computer Systems Analyst is going to have to be big-picture oriented and be able to understand very clearly how all the components work together within that particular system, including hardware, software, and networks.
Operating systems are complex structures of information, or data, that is stored in programs, files, folders, and much more. Operating systems consist of software, which are bunches of programs. An operating system is the software that stores data and information that a user inputs. The processing of input occurs through the user entering information through the keyboard, also called “keying in information.” This precise definition provides background information to the fact that operating systems are composed of a central idea. Operating systems are the key element that allows someone to use a computer. This idea sparked the creation of the first operating system in the 1960’s by the General Motors Research Laboratories.
Identify three criteria you consider to be the most important in a quality system. Briefly discuss your rationale for selecting these criteria.
Without the computer hardware I won’t be able to use the computer software for example I use monitor to be able to see and access my data, (edit it).
Technology factors relate to the system software, support for legacy systems and the IT infrastructure on which the system will be put on. Information systems are powered by information technologies which need to last throughout the system development life cycle.
As more companies that are leading technology are transforming from the traditional waterfall development model to an Agile software methodology, requirements engineering provides a process for software engineers to understand the problems they need to solve (Martin, Newkirk, & Koss, 2014). It is of key importance to understand the customer 's wants and needs before beginning designing or building the computer-based solution, as developing a solution that ignores the customer’s needs provides value to none of the parties involved. Thus, the intent of requirements engineering is to produce a written understanding of the customer 's problem (Pressman, 2010). Work products that are available to communicate this understanding include user scenarios, function and feature lists, analysis models, and specifications. This paper provides an evaluation of requirement patterns, an assessment of problem solving techniques most effective, a descriptive explanation of the patterns that includes a visual taxonomy, and an explanation of how the patterns identified are related.
Graphic cards, also called graphics accelerators, can speed up both 2D and 3D graphics rendering. Some programs rely so heavily on the video card, that they will not run if a supported video card is not installed.
An Operating system is system software that controls the system’s hardware that interacts with users and the application software. As we all may know, Windows Microsoft has always been a commercial high-level sale in the retail industry and an in domain operating system used today. But there are more operating systems than just Windows Microsoft than the general population may assume. Linux is another well-known operating systems, which is free and open-source software. Linux is also used in companies we would have never thought of like Google, NASA, USPS, Amazon and many more companies. Linux and Microsoft operating systems have been in competition to see which one is the best operating system in the market. There are so many resemblances
systems are able to run for the most part by themselves. For this paper, I will be discussing
RAM is used for memory caching, which means when the computer’s in operation, programs use this hardware for quick access and has memory saved temporarily for applications that’s deleted once the computer’s powered down. A CPU is what performs the large part of information processing in the computer, this tells what each part should be doing and it also proccesses requests; whether it be to turn on a cooling fan or to accept information to provide processing for words. It’s very important that the CPU is cooled well as it generates a lot of thermal energy. This heat is dissipated using a CPU cooler which often consists of a heatsink and fan. Newer technology is using liquid cooling and a radiator, which is a quiet solution to keep the CPU cool. The GPU is what processes graphics to create a display. Some graphics cards are powerful enough to provide viewing in multiple displays. A higher performance graphics card requires direct connection to the power supply as the motherboard can’t keep up with the power consumption of the card. Graphics cards can be combined to work together to process graphics. A cable linking
computer architecture Computer architecture covers the design of system software, such as the operating system (the program that controls the computer), as well as referring to the combination of hardware and basic software that links the machines on a computer network. Computer architecture refers to an entire structure and to the details needed to make it functional. Thus, computer architecture covers computer systems, microprocessors, circuits, and system programs. Typically the term does not refer to application programs, such as spreadsheets or word processing, which are required to perform a task but not to make the system run.
An Operating System (OS) is an interface between a computer user and computer hardware. An operating system is a software which performs all the basic tasks like file management, memory management, process management, handling input and output, and controlling peripheral devices such as disk drives and printers.
