Why is a flash drive an input devices?
A: It is both in input and output device. data can be stored there and also retrived from there
Where can you find devices such as a thumb drive that you plug into your mac?
When a device is plugged into the system, what happens is dependent on what the device is, and what its capabilities are.
If you plug in a USB HUB, it will not appear anywhere. If you plug in a camera, it depends on whether the camera has a file system that can be read by the computer.
If you plug in a printer, it will appear in the system prefs under printers. It won't appear on the desktop.
If a hard drive or memory card or thumb drive has a readable file structure, it will appear on the desktop.
So, what happens depends on what is connected to the system.
Just plain old thumb drives usually work fine in any computer.
What did John Backus introduce in 1957?
FORTRAN was introduced by him in 1957.
he worked for three years on this subject and later invented it.
He was the leading member of the team of FORTRAN developers.
He started developing it in 1954 and completed it fully in 1957.
Why UPS supplies the power that can be utilized to the largest extent when the main supply stable?
There are UPSs made with an automatic bypass switchthat when the main supply is stable bypasses the UPS and connects the device directly to the main supply. However these are more expensive than the kind that always runs power to the the device through the UPS, also the bypass switch is a break before make electromechanical relay. The "transfer time" of such a relay is measured in milliseconds and is often longer than one cycle of the main supply power. Thus when the main supply drops out power is lost to the device for this period before the bypass switch connects the device to the UPS. For some electronics this brief loss of power is no problem, but some electronics (particularly computers) cannot tolerate it.
For computer UPSs it is thus generally safer to design them to always power the device from the UPS, not the main supply. Such UPSs are also sometimes called "zero transfer time UPSs".
Another issue with UPSs is the shape of the AC waveform they deliver: many early inexpensive UPSs delivered squarewave AC, whereas more expensive UPSs delivered stepped pseudosinewave AC; certain devices (especially those with AC motors in them) could not tolerate this and would not function or in some cases were damaged. Thus the true sinewave UPS was developed, which of course was more expensive and more complicated than the other types. It is always important to buy a UPS that is compatible with the device it will power, false economy here will in the long run be more expensive.
Is a turtle a input or output?
A turtle is generally considered an output in the context of programming environments like Turtle Graphics, where it acts as a visual representation of commands executed by the user. The turtle moves and draws based on the input commands given, such as "move forward" or "turn," producing a visual output on the screen. In biological terms, a turtle is an animal, not classified as input or output.
How much electrcity can you save by using Standby instead of shutting your computer off at night?
You don't save money when TV/Laptop, PC is on Standby both when it is turned on or Standby you save no Electricity.
Which hardware is used to select links?
A pointing device.
There are many different types of pointing devices: mice (probably most common), touchpads (common on laptops), touchscreens (on tablets), trackballs (getting rare), lightguns (generally obsolete), etc.
What is an indication that an inadequate power supply is the source of an intermittent problem?
the power supply whines when you first turn on the system
What is the formula for voltage?
Voltage is the current times the resistance or
V = I R
Voltage= Current × Resistance

**This is the equation for "Ohm's Law". It assumes that you are evaluating an Ohmic device or circuit.
What term is used to refer to components that are commonly replaced but not repaired?
Field Replaceable Units
An INF file is a text file that contains all the information necessary to install a device in Windows O.S where INF stands for information.It links the device to its driver, i.e, it registers the device to work with the driver. This INF file contains information about the driver, its location,which OS the driver is meant for, manufacturer,version no,etc. . When INF file is installed, it updates the registry entries. These registry entries tell the O.S. what driver to load when the specific device is connected.

What are computers used for most?
Computers have a wide variety of uses by each person.
The most common use is communication(email, chat, AIM, etc.) and research and news(internet). Other uses include word processing, creating spreadsheets, inventory recording and maintenance, creating visual aides for meetings/presentations.
How do you replace a USB plug?
I found this after a search:
http://www.computerstuffs.co.uk/pcmodding/electronics/mobo_usb.html
I had the same problem, but I just resolved it!
Here is how I did it:
1- Create a personal folder, I assume you know how to create a personal folder (if you already have one, you may choose to close it, or you can keep it).
2- Open Outlook and click on contacts folder, right click on the folder and copy contacts, select personal as destination to copy folder.
Now you have copied the contacts folder to your personal folder. You need to copy the personal folder to a CD, flash drive, or any other portable storage device. Note: you need to close outlook to copy your personal folder.
4 - Go to the destination computer where you want to copy contacts to and copy the personal folder to a location in your local drive.
5 - Open outlook and add the personal folder (you may close your existing personal folder)
6 - Once the personal folder is there, click on contacts, you should be able to see "personal folder contacts" along the outlook contacts. You are done!, you can play with the contacts the way you want.
Why does a computer keep crashing after installing a new motherboard?
If the motherboard was not an exact replacement for the one that was removed, Windows may be trying to load incompatible drivers. A clean reinstall of Windows would likely alleviate the problem.
How do you reformat external drive with command prompt?
Providing the external hard drive is attached to the pc.
go to my computer, to find the drive letter of the hard drive. ie drive (E)
go to start, run, and type in cmd
a black DOS screen will appear.
from here you enter
format
it will say all data on this drive will be lost
do you wish to continue Y or N
hit Y, and the drive will be formatted.
Once complete it will ask for a drive name or press enter to continue.
Hope this helps
be safe
What is the function of an anti aliasing device?
An anti aliasing device uses the technique of minimizing distortion when presenting a high-resolution image at a lower worst quality image. Anti aliasing devices are often used in photography, computer graphics and digital audio among other things.
