How can you tell what BIOS your computer has?
The AMI or Award BIOS id appears at the bottom of your screen after power on, during memory count up. The PAUSE key should work at that point, allowing you to write down the BIOS number, the BIOS date, and the version. You must copy it exactly. Another (easier) way to get the Award/AMI BIOS ID is by downloading the BIOS Agent Plus software which will scan your PC and return your BIOS ID among other hardware information.

How do you open the case on a dell deskop computer?
Disconnect power and video cables from monitor. Place screen on table, back side up. Remove 4 Phillips head screws that hold the stand to the back of the monitor case, and remove stand (base). Flip monitor case up, screen facing you and bottom up. On the bottom edge by the two corners, approximately 1-1/2 inches from the sides, there is a small rectangular slot between the screen bezel and the main case. Start on the right side (not side with power switch) and insert a flat blade screwdriver in the slot and give it a twist clockwise, prying the bezel corner off the case.
Observe the plastic clip on the bezel with three holes in it to the right of the slot as you pry open off bezel. There are four more clips like that one on the bottom edge of the bezel. Insert a sharply pointed knife (a steak knife or similar) between the bezel's surface and the case's inner surface, and slide it to the left, pushing the point toward the other clips. They will pop open as you go. Next, do the same on each side, and finally on the top edge. This will completely loosen the bezel from the case.
There is a small printed circuit board with the power and other control switches and it's cable to the monitor's chassis, mounted on the bezel by three small Phillips head screws. Unscrew them and remove the board from the bezel. Now you can lift the entire chassis out of the rear case.
To access the inverter/power supply printed circuit board and others, remove the small screw in the cover shield and slide it in the opposite direction of the arrow and remove the cover. Do the same for the other cover (no screw there), to gain access to the plugs underneath. Carefully unplug the 4 CCFL cables, and make note of their positions and color orientation. Unplug the large LCD panel cable by squeezing the sides of the plug and pulling on the plug (not the cables) to free it. After removing the two screws on each side of the chassis, you can remove the LCD panel from the chassis cover, exposing the inverter/power supply and VGA input boards. Place the panel in a safe place to prevent damage. You are now ready to make repairs!
Is a soft boot more stressful on computer than a hard boot?
Soft boot is less stressfull for your computer!! (Control-ALT- Delete) Hard boot is rough for your computer!! And it takes longer:( People argue all the time about which way is better to shut off your computer so I don't know if this is the truest answer!!
A microprogram is a program that is consisted of micro code, which is the lowest level language possible on a computer. Microcode is even more low level than machine code and acts a platform for machine code to run on top of, directing the physical operations of the processor by itself.
Why is correct data entry important?
The speed of production today makes the accessibility of precise, comprehensive information an absolute essential. Whether your corporation is multi-national or just starting off, the more you know about markets, customers, or clients; the better you can track results, measure efficiency, and analyze data; and the faster you have vital information, the better your results will be. This holds good for corporations, physicians, attorneys, automobile manufacturers, hospitals, marketing companies, and just about any other business you can imagine that needs information fast. Businesses are always looking for the information that will help them run day-to-day operations or to plan for the development of future growth. Customer satisfaction surveys are a constant of modern life as are comment cards, coupon mailers, and contests. Some companies can be virtually overwhelmed by the amount of data entry required just to keep things moving. This can be especially true of medical facilities, insurance groups, collection agencies, and marketing companies.
When a serial port is used by an external modem the serial port is called the?
In the past external modems connected to the COM (or serial) port.
However, most modern external hardware is USB these days, modems are no exception.
How do you add new hardware to a computer?
Just follow the directions that come with the hardware. Every piece of hardware I have added in the last 20 years had instructions on how to install the hardware. Be sure to read them COMPLETELy before starting to install anything.
This ASSUMES the person has the documentation. If you want a more specific answer, then the question needs to be more specific as to which hardware that one is installing.
Yes. There are 1000 KB in 1 MB, so 16 MB is 16 000 KB.
Note! This is only approx calculations. It's actually 1024 KB in 1 MB, but that's not necessary for the calculations in this case.
Mainframe is used in business where the data to be processed is too huge and has to be processed too many times and may require too much CPU cycles where the else of the computers may flunk.
Mainframes are very similar too supercomputers ahich can process huge number of transactions in small amout of time . but the only diff between supercomputer and mainframes is supercomputers are used to calculate and process complex algorithms say which has so many integration and diffretiation and lotssa calculus steps where as mainframes are used to handle simple business related calculations like addition and subtraction kinda things .
- - - - -
First understand that any company that has a mainframe is pretty big--an insurance company, a carmaker, someone like that. They will use it for several things:
It's got the company's databases on it. One of the databases might be a list of customers: it will list the customers and usually all the things they've ordered over a certain time period. You can do this with a PC, but mainframe databases can get much larger and they've got more features.
It's set up to share resources. All the company's printers will be hooked to it. When you send a print job to it, you can tell it to print only to one printer, or to any printer that's available and capable of taking the job.
These days corporate e-mail will go into the mainframe.
And sometimes you run programs on mainframes, but that was mostly done back before PCs got so prevalent. When all you had was a "dumb terminal" like an IBM 3278, the mainframe had to store plus process your data; today a lot of processing is done out on the PC and completed data is sent back to the big iron.
-----------------------------------------------------
Simpler, a mainframe is only a way to designate the main node withing an array of computers linked by networking. In other words, he the big kahuna!, but it doesint mean he's the most powerful!.
Mainframe = Node 1 = Computer #1 = Big kahuna

What are Limitations of cache Memory?
size. cache memory is situated on the CPU, and stores recently used data, in case the CPU needs again soon. cache memory is many, many times faster than RAM, just RAM is much faster than the HD.
What tool can you use to create a console containing device manager?
Windows comes with many applications for administering and managing the system. In older versions, these programs had to be used separately. In Windows XP, there is an interface that can be customized to contain in one package all the system tools that a particular user employs on a frequent basis. For networks or multi-user systems there are also a variety of security settings that can be made within the interface. Microsoft calls this interface a "management console" and generally refers to it as MMC. A computer user can choose which of the many available tools to include. The individual tools are referred to as "snap-ins". A console has a hierarchical structure with folders and in fact resembles a Windows Explorer tree.
Many of the system tools that come with Windows XP are already in a console form. They can be used alone or as snap-ins to a console that contains a collection of applications. The sidebar on the right lists the preconfigured consoles most commonly used. These are found in the folder \Windows\System32\. Depending on your setup, there may be some in other locations as well. (Some of these come only with the XP Professional version.) Note that the consoles have the extension msc (not to be confused with MMC). Most of these consoles can be opened by entering their names (including the extension) in the Start-Run line. Some, but not all, are also accessible from Control Panel. Depending on how your computer is set up, some may also be listed in Start-All Programs-Administrative Tools. As is common in Windows there are also several other ways to open some of the tools. However, using the Run line is probably the easiest way. (A few consoles intended mainly for systems administrators may be in folders not included in the standard path environment and will need the Run line browse function)
Some of the consoles that have specialized purposes for use by systems administrators may not normally be of interest to the average PC user.
devmgmt.msc- the Device Manager
eventvwr.msc- Event Viewer for managing system logs
http://vlaurie.com/computers2/Articles/mmc.htm Simply use mmc.exe and add snap ins into the console.
Type MMC into the run box and add these as snap-ins into the console.

the advantage and use of computer mouse is to click icons. by using mouse is faster in terms of pointing in to an object on your computer. unlike by using keyboard, you need some keyboard shortcuts in order to execute or click an object.
What are power connectors use to provide power to CD drive?
Most common is a 4 PIN connector that comes conntected to the power supply or jumped from another 4 PIN connector. The pins will be in a streaght line. There are now also SATA power connectors that once side "flat and long" connects the the CD drive and the other "fat and short" 4 PIN female end to connect to a 4 pin male end
How do you refill Epson Ink Cartridges?
you need a chip resetter to rifill these cartriges
The ink cartridges used in Epson's Stylus line of printers are very similar to the ones used in its other printers. A handful of cartridges--like the S020034, S020047 or S020049--may require a slightly different refilling technique, but they all basically entail opening a fill hole in the top to run down into the ink chamber within. Once the chamber is accessible, you can use a basic refill kit with a syringe bottle to refill the chamber, as with most printer-ink cartridges.
1.Hold the cartridge upside down so the outlet holes to the printer paper are on top. Cover each hole with a piece of tape, then turn the cartridge right-side up.
2.Make a hole in the top of the cartridge above each ink chamber. For most cartridges, simply poke a hole through the label with a toothpick. With cartridges like the Epson Stylus 34 (the casing of which is black), pull back the label to reveal the filling holes and puncture the seal of each home. For the 47 or 49 color cartridge, drill a 1/8-inch hole in the shell between the label and front edge.
3.Determine which color of ink is in which chamber (if you're refilling a color cartridge). The toothpick used to puncture the hole should draw out some ink to show you. If you have a cartridge in which you punctured the label directly, the order of the color chambers is usually cyan, magenta and yellow. If you created the hole in another way (like with the 34, 47 or 49 cartridges), the order is usually magenta, cyan and yellow.
4.Fill the syringe bottle with 5ml of ink. Insert the needle in the filling hole and inject the ink. There may be a sponge inside the chamber, so make sure the needle goes all the way through to the bottom. The 34 cartridge takes up to 12ml of ink.
5.Tape over the fill holes you created. If you drilled the holes, plastic plugs (like the ones included in a refill kit) can work as well. Leave the tape on the outlet holes as you replace the cartridge in the Epson Stylus printer.
6.Run a cleaning or priming cycle on the printer with the cartridge installed. One to three cycles should be enough. You may also need to let the cartridge stand in the printer overnight, or for up to 24 hours.
