A port replicator is used in docking stations for laptops to increase or extend the number of ports available for use and minimise the need to plug / unplug cables when removing the laptop from a desk.
A port replicator may also allow for additional hardware such as a CD / DVD or Bluray drive for which there may not be space in the laptop.
What is the difference between General Processor and DSP?
DSP's are mainly based on Harvard architecture to perform task faster with hard wired instructions as compared to Microcontrollers which are mainly available with von neumann architecture (some microcontrollers like PIC is an exception).
The DSP can compute the numerical parts of your application faster than the microcontroller can. Because that's what it's designed to do. You might also find that DSPs have more of the "right sort" of integrated peripherals, compared to microcontrollers.
Is a scanner a in or out device?
It is an input device. Like other input devices, it takes information so it can be processed/stored. An output device, on the other hand, takes care of the displaying or presenting of already processed/stored information.
How do you move photos from memory card to flash drive?
==Windows== One needs to plug the flash card into the computer in some way. If it is USB, simply plug it into the USB port in the back or front of your tower. If it is an SD card, you'll need a "Card Reader" in order to put it in. Most USB flash drives are "Plug & Play" in that they should install within 10 minutes of being plugged in to the PC. After, head on over to "My Computer" and you should see a "Removable Disk Drive" or "Removable Drive" or similair, open the drive as you would a folder (double click it) and drag and drop files. ==Mac== A USB icon will appear on your desktop after the flash drive is plugged in. It looks similair to a Hard Disk icon but is white. Open it, and drag and drop files onto it.

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!

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 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.
