Does Windows 2000 Professional and Windows XP Professional have the same minimum hardware requirements?
No, XP has higher requirements then 2000, most notably needing more RAM. Windows 2000 Professional 133 MHz or more Pentium microprocessor (or equivalent). supports up to two processors on a single computer; also supports dual-core computers; 64 megabytes (MB) of RAM recommended minimum. 4 gigabytes (GB) of RAM is the maximum; A 2 GB hard disk that has 650 MB of free space. VGA or higher-resolution monitor; Keyboard; Mouse or compatible pointing device (optional). I can tell you from personal experience, it runs great on a 400 celeron, 128 MB RAM, 4 Gb hard drive (but 2000 Pro is 1.5 GB installed). XP Home or Pro 300 MHz CPU, supports up to 2 CPU,s, including Dual-Core. 256 MB RAM, but it will be slow. If you do more then 1 thing at a time (almost everyone does), such as open a word document while surfing the net, with an anti-virus program running, it will be PAINFULLY slow. I know many people who went from 256 to 512 and could not believe how much faster it was. Consider 512 MB RAM the minimum). 4 Gb HDD (hard drive), and XP will take 1.5 of it (if you have a 15 GB or bigger HDD, XP will take 2.25? GB of it). I tested XP Home on the 400 Celeron; 256 MB; 4 GB hard drive, and it was noticeably slower then the same computer with 2000 Professional. I would say it was a combination of not enough memory and too small CPU (consider 1 Ghz the minimum). For more information, search Google for "2000 requirements" and "XP requirements"
With an Intel Pentium III processor at 750 MHz a 20 GB hard drive and 128 MB of RAM can you make your computer faster with an external hard drive and use a USB Flash drive as RAM?
No. The USB 1.1 found on a Pentium III system is far slower than the memory or IDE bus. You would be better served by upgrading your RAM.
What type of fiber-optic cable is used most frequently on LAN?
Most likely Multi-Mode, as it is a cheaper connection method when the connection will not be over a long distance. It transmits data anywhere from as slow as 10 Mb/s to as fast as 10 Gb/s. It is most commonly used in buildings and and on college campuses. It is no faster or slower than Single-Mode Fiber Optics, rather it has a maximum transmission length of 3000 feet at the given speeds.
What is the difference between shaped and unshaped broadband?
Essentially, a shaped connection means that once you reach your plans download limit, for example, 30GB, your connection speed may drop to a slower speed, in most cases between 64 kb - 512 kb, where you can continue to download and use the internet but at a slower speed. If a connection is unshaped, then once you reach your download limit, in this case, 30GB, either: a) your connection will be suspended till the next billing cycle commences. or b) you will continue to be able to download and use the internet at the same speed HOWEVER you will be charged a certain ammount for each extra megabyte/gigabyte. depending on your ISP. Personally, I prefer shaped, as here in Australia most isps charge you almost $1 per megabyte extra, so if you accidently go over by 30MB, you have to fork up another $30.
Why do computer have hard disk?
Hard Disks (or hard drives) are mainly used for Primary Storage. Typically most of the data on the computer, and the operating system, are stored on the harddrive. Without a hard drive or similar long-term storage, you would have to store data in RAM. RAM is volatile (temporary) memory which clears when the computer is turned off. Whereas hard drives will store data reliably without power, provided the hard drive and computer are functioning correctly. Hard drives may also be utilized as overflow space if the computer runs out of RAM. Which harddrives are much slower (typically 50-100 MB/s) than RAM (1,600-8,000 MB/s) it is also far, far larger. Most harddrives are from 80 GB to 2,500 GB these days. This allows virtually limitless space for RAM to overflow to, and allow the system to keep functioning in the event of a RAM shortage. Computers typically only have 4 to 32 GB of RAM.
What determines how much ram you can use?
There are four different types of RAM being used or not used... 1...- Free RAM: Lets say there is 600 megabytes of free ram on your mac os x computer. You open up google sketchup 8 and use it. This takes about 500-900 mb of ram and so your computer would be sufficiently slower than if you had 1.5 gb of ram left. 2...- Wired Ram: This is the ram you will NEVER be able to use. IN mac os x (and i believe windows and linux), wired ram is used to save the kernal and all of its processes. For example, my macbook shipped with 2 gb of ram. However, I am only able to use a little less than 75% of actual usable ram (in programs) because 500 or so megabytes are dedicated ONLY to saving the kernal and processes. 3...- Active RAM: The amount CURRENTLY BEING USED. This is important because it helps determine the amount of free RAM on your computer. For example: 2 gb of RAM minus 500 mb of wired ram minus 1 gb of active RAM minus 400 mb inactive RAM equals about 100 mb of RAM left (free ram). This means i have got to be careful which programs I open right now! 4...- INactive RAM: Inactive Ram is NOT free ram. It is used primarily to save processes (temporarily, unlike wired ram) and open programs up faster. For example, on my Mac OS X Snow Leopard computer, it takes about 14 seconds to open up Microsoft word 2008 after a force quit. If I do not force quit it after closing the program, and then open it up again, then MS Word 2008 opens up in 6 seconds! (Most of) This can turn into free ram IF you force quit or stop running programs. Then I bet you your computer will become at least a little faster for the time being.

Is 1 meg of internet connection a good speed?
it's okay i suppose but depends a lot on your location and proximity to an exchange. I would be happy enough with it but i only surf the net and don't do much downloading or uploading. In a big city it probably should be faster and in remote areas possibly a lot slower.

How much ram do you need to emulate PS2 games on a PC?
Note: RAM should be capitalized as it is an acronym for Random Access Memory..The current build of PCSX2 (1.2.1 as of May 2014) will only run at full speed on high end consumer processors (i7 2600, i7 4700k, etc), a high range video card, and at least 6 GB to 16 GB of memory. It will not run at full speed on the AMD Phenom or Phenom II as these CPU's lack certain types of instructions sets (SSS3 & SSE4.1) that are critical to the operation of PCSX2. The Phenom will instead run on the SSE2 instruction sets, which is slower..The fact that the real Playstation 2 hardware only used 32 MB of system RAM and 4 MB of video RAM has no bearing on the amount of RAM a PC needs to emulate the Playstation 2. The reason the RAM is needed is so that a working model of the entire logic of the Playstation 2 console can run in resident memory of the computer. The proprietary design of the Emotion Engine (particularly its variable 128-bit bus) is extremely difficult to duplicate accurately. The CPU of the PS2 had many elements within the dye that dynamically interacted..There are ways to get the PCSX2 emulator to run with less RAM and on slower computers than the i7 series, such as the Core 2 Quad and Core 2 Duo. These CPUs do support SSS3 (and some even support SSE4.1). However, this involves using special settings and speed hacks, which reduces the quality of the emulation significantly..The graphics card is also important. Although the Playstation had very primitive graphics capabilities by today's standards, the way the graphics bus and CPU bus interacted with each other is difficult to duplicate. Although most video cards with Pixel Shader 2 capability will run PCSX2, to actually run the emulator at full speed a more powerful video card will be required. Again this is because the logic of the graphics system has to be duplicated, not just cell shading for backgrounds and character models. To see real PS2-like performance you are going to need a video card like the GTX 660 or the HD Radeon 7870. Again you can get the emulator to run on slower cards (with speed hacks and special settings) but the quality of emulation will be diminished..PCSX2 is the only PS2 emulator, and its minimum requirements are outstanding..Requirements (will simply run the emulator):Processor: Intel Core 2 Duo 2.4 GHzGraphics card: 7600 GT with 256 MB (or AMD equivalent)Memory: 4GB DDR2 (some graphics may disappear as memory runs out).Recommended (to actually play games):Processor: Intel Core 2 Quad 2.80 GHzGraphics Card: 8800 GT with 512 MB (or AMD equivalent)Memory: 6 GB to 8 GB DDR3.Recommended (to play games at full speed):Processor: i7 2600 (or better)Graphics Card: GTX 660 (or better)Memory: 8 GB to 16 GB DDR3.Visit http://pcsx2.net for pcsx
Why does 4 GB ram only show 3 GB?
AnswerIf you are using two memory modules in your computer, make sure both are inserted properly. If you remove one and the system still works, you know which one is not inserted properly.If you are using a 256 MB module, you may have purchased a low quality module made using "low density" chips. These modules use slower chips to produce a memory module. These are incompatible with most chipsets, and are not standards-compliant. They usually only work well in low-end systems.
Is a one gigabyte laptop computer good?
your laptop will run slower then anything when you store documents movies music ect
What is the memory used for?
Permanent storage tends to be slow. For disks, there there is rotational delay while the disk rotates beneath the read/write head, and seek delay as the head moves across the disk from track to track. Tape is even worse, and little used anymore. The memory serves as the storage area where programs and data are loaded. The programs are executed from memory. Each program instruction is loaded into the central processing unit (CPU) and executed there. Instructions are commands, such as add the contents of two registers, or branch to a location in the memory, or fetch the data at a particular location in memory, etc. Memory tends to be much smaller than disk storage. Currently typical home PC disk capacities range from a hundred gigabytes up to a terabyte (a trillion bytes). A typical digital photograph takes up approximately 2 megabytes. In a hundred gigabytes you could store roughly 50,000 photographs. But computer memory generally ranges from 256 megabytes to a gigabyte. Some of this space will be consumed by operating system software, and some of it by programs. Programs that are executing in the background take up some of the computer's memory, like the program that checks your e-mail, and so on. Image editing software takes up a lot of memory space. So if your computer has 512 megabytes of RAM (random access memory), maybe half of that would be left over for data, or less. JPG images are probably translated into bit mapped format in the computer's memory to make manipulation easier--which would leave even less space--maybe room for only a handful of photos. You will get an idea because the computer will suddenly start running a lot slower when too many images are loaded into memory, as some of that memory will be swapped back out to disk as you switch between tasks.
