I installed a new two port USB PCI card in my emachine and when I attempted to boot up my computer I got the following message cannot find OS.....What happened?

Most likely the computer is trying to find a boot device on the USB port. Check the BIOS settings to make sure the computer isn't looking at the USB for boot data.

How did the modem get its name?

To send digital across an analog wire the signal is first laid on top of an analog signal. The process is called "modulation". It's the same thing that's done with television and radio, it's just a different type of signal.

The modulated signal is sent across the wire and the MODEM at the other end receives the signal and decodes it.

The process is called, "MOdulate, DEModulate, or more simply, MODEM.

What are the basic functions fo r an ide and eide?

IDE and EIDE are effectively the same interface. The difference is that EIDE is an enhanced peripheral interface, allowing for high-speed data transfer and lower latency communications. E means 'Enhanced'.

EIDE was typically used to describe Ultra 33, Ultra 66, Ultra 100, and Ultra 133 ATA modes with DMA (Direct Memory Access), rather than older PIO (Peripheral Input/Output) modes which were slower and required more overhead.

It has often been mistaken to mean 'external'. This is not correct.

Docking stations are usually smaller than port replicators and do not have speakers or PCI slots?

It is not true that docking stations are usually smaller than port replicators. It is true that port replicators are typically smaller than docking stations. Port replicators usually do not have PCI slots or speakers.

An external modem connects to a computer using which port?

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.

What is front side bus speed?

The front side bus connects the CPU on the motherboard to the Northbridge. Front side bus speed is in preference to how much data can move across the bus simultaneously, and is measured in megahertz.

What is COM1 used for?

COM1 is seldom used for anything these days, and may not even be mapped to a physical device on newer systems. Its primary purpose is/was to serve as a communications port, either to an internal or external modem, or as a connection into a mainframe computer. It has also seen some use as a general purpose expansion port and been used to attach mice, printers, and cameras to a computer.

How much data will the DVD hold?

4.7GB on a standard DVD - can be a duel layer disk (double sided) which holds 9.4GB

What are the two types of damage that electrostatic discharge can cause in an electronic component?

they can cause your system to malfunction or it may make your system erase all or your data

What is a Default Getaway?

A defalt gateway is a type of computer software that isn't modified from the present, or classical for of the gateway. The primary purpose of the part is to clearify visual images. Cookie monster FTW

What is the function of a rubber connector?

Rubber connectors that are impregnated with carbon or metal are good. They they are flexible and low profile. So this means that they can be used in very tight places. For instance, that is how the circuit board of a digital watch connects to the display.

How does networking improve the usefulness of computers?

Supporters of technology say that it solves problems and makes life better. Opponents argue that technology creates new problems that may threaten or damage the quality of life. There are several viewpoints on the implications of technological change and advancement and such schools of thought which considerably vary have their respective validity. Technological change has its advantages and disadvantages. For one, it is true that it partly solves problems and makes life better. At the same time, technological changes may likely create new problems thereby threatening or damaging quality of life. In the developing economies, for instance, technological advantages have both its merits and demerits. The introduction and seeming acceptability and usefulness of computers have somehow helped increase the efficiency of several firms. It is not only in the industrial sector that technological change proven to be very effective. In the agricultural sector, for example, the introduction of new technologies in increasing production has been very effective in expanding agricultural produce. These are just a few examples to illustrate the advantages of technological advancement. On the other hand, countries should be more careful on their choice of technology since it must be noted that while certain types of technology are adaptable to developed economies the same type of technology may not fit the environment of developing countries due to differing economic, social, cultural, and political factors. For example, infrastructure improvements such as a construction of irrigation dam in the mountain of the Philippines where several natives reside may likely be resisted by the population due to cultural factors. They may prefer not to have such improvements in view of traditional values. Another example is the pollution impact of some technological improvements particularly in the industrial sectors. The choice and adaptability of new technology should therefore be carefully studied. The short, medium, and long term impact of such technology is very important particularly for developing economies. The benefits should always be greater than the costs. I am inclined to support both positions because both views have their own validity. However, I am more convinced that technological advancement is really beneficial to countries so long as they are aware of the disadvantages of such technology. In my own points of view, I support technology can solve problems and makes life better. Computer helps human solves thousands of problems, especially, science. A lot of calculation was so complex. It is impossible count them from normal method. It should use a very fast computer in order to compute it. Super conductor, one of the hot technology topic. A lot of scientists study this kind of stuff. It is a very important stuff. That is wonderful. We can easily solve the big problem, "energy". It can pass through the energy without losing. Finally, I support technology. Because it is more benefit.

Is the red plug on an RCA cable right side and white the left side?

White is Left and Red is Right , White is never right is another way to remember. This question has been answered by Hoffman from Batavia New York

What are the uses of fiber optic?

fibre optics tranfer data through total internal reflection so the data loss in negligable as comparied to metal wires available in the market.So the main use of optical fibre is "the optical fibre cables"

but there are other uses as well..

  1. It can be use as censors.
  2. It can also be used to transmit power using 'Photo voltiac cell'.
  3. It is used in most HD-televisions as digital audio optical connection.
  4. It can be used as Fuse.

What are system resources?

anything connected to the cpu is a system resource

What is PCMCIA stand for?

PCMCIA stands for Personal Computer Memory Card International Association. It is a standard for externally accessible expansion slots that accept cards that are compatible.

What does 'DMI Event Log space full' mean?

The DMI Event Log is a recording of errors encountered by the BIOS during the boot process. A system administrator or technician can examine the log to view possible problems. Since it is stored on a Flash memory chip, which are comparatively expensive, the space that can be allocated to the log is very limited. This error message means that the log needs to be deleted so that new recording events can occur. Most systems will, however, simply erase the oldest entries automatically.

What is an output unit?

anything that sends a signal out of the computer. Such as a monitor or printer. your keyboard and mouse are the input

or

It display the data,program,pictures on the screen.it points the data,program,pictures on the point.it point the graphs on the graph plotter.it produce music etc on the speakers.it shows the data on the multimedia.(Anis kazmi)
