...NT1110 Unit 8: Analysis System Performance Slow or sluggish system performance can be frustrating. There can be one or more things causing the slowdown of performance. Too many processes running in the background is only one issue of many possible reasons why the performance is sluggish. Virus, worms, and malware is another reason that can take up system resources and severely slow down a computer. By taking the necessary steps, one can improve the system performance of a computer. First one can perform routine maintenance like defragging a hard drive, cleaning up a hard drive. Checking the hard drive for errors and uninstalling unwanted programs will keep the Performance optimal. Checking for hardware and software compatibility and dealing with those issues will greatly enhance system performance. If there is a compatibility issue, address the issue and see an improvement. Address all system warnings that the OS alerts you too. One can resolve an issue by simply clicking on the warning popup window to help address the issue. Check the reliability and performance monitor. This feature in windows vista keeps a record of all past performance records and one can see when the problem started to have issues. One can accurately pinpoint the program or hardware that was installed when performance issues started happening. Disabling Windows Search indexer, vista aero interface, and vista sidebar will speed up your computers system performance. Those programs use up...

...System Performance: Unit 8 Edward Greene NT 1110 When addressing system performance, a key element that is often overlooked is Disk Fragmentation. Even on a brand new system with plenty of RAM and processing speed, the performance of the hard disk may be a bottleneck causing issues. It takes time to load large data files into memory - issues become particularly noticeable when dealing with movies, video clips, database files or image files which may easily be several gigabytes in size. On a freshly formatted disk, these files load fairly quickly. Over time, however you may start to notice performance issues - caused by disk fragmentation. The different processes running in the back ground, (i.e. Windows Explorer, Power Manager) all take an allotted amount of RAM to perform at optimum levels. More free RAM means that the essential processes that are running have more priority of the space and the CPU. When you begin to run your RAM to its limits, The essential processes and even the non-essential processes begin to lag due to the overtaxing of the CPU and RAM. Your OS will use the hard drive as a “back-up” or virtual memory if your PC runs out of RAM while you are working away. Using your hard drive as memory causes a serious performance hit, as hard drives are way, way slower than RAM. So, the trick is having enough memory, adding more does not help if you are doing nothing that needs more memory. Today, with a modern PC and a modern OS, you need about 4 gig to achieve...

...Corey Young Monday The first part of this video was talking about the history of the operating systems. The Microsoft OS were DOS that had a GUI interface, after that you had NT, 9x, 2000, XP, Vista which in my opinion was terrible, server 2003 and 2008. There are also other OS that have been out Unix and Linux is what Macintosh are built from and then you also have Mac OS X. Video 3.02 was talking about installing new hard ware, creating partitions and formatting partitions, and installing OS systems. Before you install an OS system after installing a new hard drive you need to create and format a partition which will be an c partitions. There are two types of partitions which are primary and extended. You can only create one of each with the FAT file system. The NTFS you can create four primary partitions or three primaries and one extended. In creating partitions you need to know the order they are created and deleted. The orders to create partitions are first primary then extended and logical. To delete a partition you will simple reverse the order. Video 3.03 is about comparing active, system and boot partitions. After creating partitions you need to mark one active which usually contains the boot file so you can start up the OS. The system and the boot partitions are part of this system. The system partitions contain boot files which contains the operating system which boots up the OS. The boot partition contains system files which contain the OS files. So the...

Port expander are hardware device designed to allow a user to utilize more than one device on a single port at one time. It’s able to connect several devices to one serial port, for example connecting mouse, and keyboard when you only have one USB slot to use, you would use a port expander to fix this problem. There are several different types of port available for expander hardware, but to list a few we have USB, Ethernet, Audio, SAS, VGA, Microphone, DVI, and Video ports.( see pictures below). Port expanders are made generic so it’s compatible with most computers if not all, as long as the computer has the ports for which you are trying to expand for. With anything there are always disadvantages, and advantages. Disadvantages to port expanders are that whenever you have it fully connected it takes away performance from all devices since they all share the same bandwidth. Example if you have a 6GBps port expander which can connect up to 8 devices, when all connected creates a traffic jam making the performance slow creating a bottle neck effect. Also most are external, requires a lot of power, for this reason you possibly overload/ruin the power supply, or PC may not start till all is disconnected. Advantages to port expanders are that it...

...Ariel Torrente NT1110 Unit 5 Analysis Pentium Flaw Ariel Torrente NT1110 Unit 5 Analysis 7/27/2013 Pentium Flaw The Pentium flaw also nicknamed the Pentium FDIV bug, was an identified error in the Intel P5 Pentium floating unit. The presence of the bug can be checked manually by performing the following application that uses native floating numbers, including Windows Calculator or Microsoft Excel in Windows 95/98 (Pentium FDIV bug). The Pentium flaw was discovered byProfessor Thomas R.Nicely at Lynchburg Collwge,Virginia USA (Emery, Vince). Dr.Thomas R Nicely is a mathematic professor, noticed a small difference in two sets of numbers, he always double-checks his work by computing everything twice, two different ways (Emery, Vince). Dr.Nicely spent months successively eliminating possible causes such as PCI bus errors and compiler artifacts (Emery, Vince). Intel wanted to keep to keep the Pentium flaw a secret, after Intel testers discovered a division error in the Pentium chip (Emery, Vince). Intel managers decided that the error wouldn’t affect many people, therefore no one outside of the company was not informed (Emery, Vince). The pandemonium over Intel’s Pentium chip cost the company millions of dollars and could have been prevented and became an uproar on the internet (Emery, Vince). This was Intel’s first mistake and the company was given a reputation that made Intel not a trustworthy company and not disclosing that information made them seem to be hiding a...
