How does the usb cable extension work?

A USB cable extension works by increasing the distance between a USB device and its host, allowing data and power to travel through an extended cable connection while maintaining communication between the two devices, and reliable USB cable extension solutions are available at EnrgTech for convenient and efficient connectivity.

Is it normal for your video cards to reach temperatures of 174 degrees Fahrenheit?

Usually the newer video cards have heatsinks on them. It may be possible for the heatsink to get to that temp. You want to be sure that your case has good ventilation and the video card is not blocked from air passage. The internal temp of the processor may reach into the or near 100 degrees C. If you have information on the card it may tell you what the temps may be. Some of the newer cards have a fan installed on them. Of course the cooler the better. It is really the temperature of the transistor junctions in side of the chips that are the real concern. The heatsink helps draw away the heat allowing the device to work.

Good luck.

What is a Paribit?

Paribit is a combination of two words; Parity and Bit. In early nineties computing, a check digit or Parity Bit was assigned to a sequence of bits that were to be transmitted over a network. The parity bit was used for security and transmission verification purposes. It either made the entire sequence of bits, even or odd, depending on the checking mechanism being used.

Transmissions today use a method called packets and does not employ the check digit method.

What is CDDi?

For a local area network (LAN), CDDI (Copper Distributed Data Interface) is a standard for data transmission based on FDDI (Fiber Distributed Data Interface) that uses shielded twisted-pair (STP) or unshielded twisted pair (UTP) copper wire instead of fiber optic lines. CDDI supports a dual-ring capacity of 200 Mbps. CDDI's maximum distance is up to 200 meters, which is much shorter than FDDI. CDDI is defined by the American National Standards Committee X3-T9.5 and conforms to the Open Systems Interconnection (OSI) model of functional layering. CDDI is officially named the Twisted-Pair Physical Medium Dependent (TP-PMD) standard and is also referred to as Twisted Pair Distributed Data Interface (TP-DDI).

Your home computer is most likely connected to the internet via a ISP?

It is absolutely connected via an ISP. ISP just stands for Internet Service Provider. It can be dial-up, DSL, cable or satellite.

2000 mbz ml320 where do the ground wires from the 2nd o2 sensors heater wires connect do they ground to the body or through the computer if they connect to the computer which pins on which computer?

On the Mercedes ml320 you should be able to ground the o2 sensor to the body of the car. Just find an unpainted section and stick its ground wire on. If this does not work, try adding an isolation capacitor between the grounding pin and chassis as well. If this still doesn't work, got to the dealer.

Why do computers freeze?

Some reasons why your computer freezes include:

  1. Running too many programs at once. (Out of RAM)
  2. Errors in your windows registry.
  3. Driver or codec problems.
  4. Buggy CPU or system BIOS.
  5. Bad RAM.

To fix a frozen computer you can either:

  • Be patient - wait a few minutes to see if it will unfreeze.
  • Restart the computer.

If the problems persist then try these:

  • Replace various system drivers.
  • Reinstall any codec packs used.
  • Use System File Checker to scan for corrupted files.
  • Try new or additional RAM.
  • See if there is a new version of BIOS (firmware) for your motherboard.

How do you upgrade your USB 11 ports to high speed USB 2?

You will need to install a peripheral card into an available PCI slot. This involves opening up the case and sliding a new card onto the machine's motherboard. You can purchase a card at most computer or office supply stores these days and it will come with simple instructions. Don't be intimidated by the inside of a computer, it's like working with Legos!

Can the power supply cause the computer to be difficult to turn on?

Yes. If the power supply is of a low wattage and has too many pieces of hardware connected to it, it can. Try buying a power supply with a wattage over 300.

One thing to check before replacing the power supply is the voltage selector in the back. If you use 120 volt power, then setting the power supply to 240 volts will cause the PC to only get half of the power it needs.

External peripherals with their own power supply will not impact the power supply or current in the computer. Printers and monitors usually get their power from the wall socket, not the computer, and the same goes for external modems that plug into the wall. Keyboards and mice take negligible power.

What are the advantages AND disadvantages of paging and segmentation?

Paging

Paging works by dividing memory into small pieces of memory (frames) and then logically divides the program into same-size pieces (pages).

Paging Advantages

Easy to allocated from free list of frames

-Physical memory is allocated from free list of frames

-External Fragmentation is not a problem

Easy to "page out" chunks of programs

-All Chunks are the same size (page size)

-Use valid bit to detect references to "paged-out" pages

Paging Disadvantages

Can Still have internal fragmentation

-process may not use memory in exact multiples of pages

Memory reference overhead

-2 references per address lookup

Memory required to hold page tables can be large

If a monitor is not giving display then what is the problem with it?

  4. Shot Displays(worst case scenario)

  5. Nothing else I can think of......

The amount of data that can be stored on a disk depends in part on?

The amount of data that can be stored on a disk depends in part on the File System used. Common types are NTFS, FAT 32 and FAT 16.

What are the advantages and disadvantages of sound card?

A dedicated sound card has the following advantages and disadvantages.

Most modern computer motherboards will have some kind of onboard audio chip which is sufficient for most gaming and audio listening. However some audiophiles may requires a higher degree of standards when it comes to their listening and may have equipment capable of detecting and noticing the shortcomings of a mass-produced, cheap, onboard sound chip.

A dedicated card will first have it's own chip which means it takes a load off the CPU when it comes to sound effects and input and output. This means the CPU could be freed up for more important tasks.

The inputs and outputs on a dedicated soundcard will usually be of a better craftsmanship then the ones on a motherboard and thus will have less analog interference. This is important on the back of a computer which is already brimming with EMI due to the myriad of devices in close quarters.

Usually a dedicated sound card will have a better DSP (digital signal processor) and will be capable of higher quality sound output and input. This means you can run a better quality of sound in and out of the card.

The disadvantages of course are price. A dedicated card can run as little as thirty dollars to as much as several thousand for high end models.

They also take up a precious expansion slot on a motherboard which could be used for other devices you might need.

Various manufacturers may have varying support for some programs and devices and hardware, always a concern. Onboard sound chips tend to be almost universal in their support, one advantage. A dedicated card might not openly support alternative operating systems such as Linux or BSD bases.

Hope this helps!

What the difference between GUI and console?

The keyboard and screen are often called the console, sometimes it's just the screen.

The GUI (Graphical User Interface) is the application programs that allow you to point and click. The idea of a Graphical User Interface is that most of the computer controls are performed by moving a mouse and clicking on icons.

To reiterate, the GUI is the application, the console is the hardware.

How do vaping devices work?

All vaping devices work in the same fundamental way: A battery powers a coil heating element that turns a liquid solution known as e-liquid into an aerosol.

Different devices apply these principals in differing ways – and it’s surprising just how many variants have been created from such a simple concept.
