Instruction INT 20H is used to?
Interrupt 20 ( AKA INT 20, int 20h, INT 20H) is the 33rd entry in the standard PC interrupt table. The '20' is hexadecimal notation (hence the use of the H or h, which may actually be required by some assemblers whereas others assume entries are hexadecimal) for decimal thirty-two (32) but counting starts from zero, as is usually the case in Computer Science.
Int 20 is known as "DOS Terminate" and will end execution of the code at that point and return control to DOS (or the DOS-like environment which called it). It looks at the CS register (a standard 80x86 register which was intended to 'point' to the segment where the code was loaded - Code Segment) and returns nothing by way of register or stack.
Simple Answer: this is an instruction used in very small and typically very old DOS programs to terminate themselves quickly and with a minimum of effort, it probably ought not to be used today, research Int 21 instead (the so-called 'DOS Interrupt').
N.B.: This instruction could also refer to other architectures and thus be very different, e.g. AIX, VMS, etc. My answer is PC & DOS specific as this is the most likely context for this question.
Let's say that you have to use another computer for the day because your personal PC is broken. You immediately pat yourself on the back for remembering to put your files on your USB Drive, until you sit down to work with them... The borrowed PC has none of the software to run your files, which is just as bad as leaving your files at home. With a U3 Smart Drive, you can hold the software necessary to run the files, as well as other files like Accomplice, which manages your to-do lists, Weatherbug for telling you accurate weather all the time, etc etc... The U3 Smart Drive can also hold games, such as Sudoku, and can allow you to put a password on your U3 Drive, giving it the ultimate protection from data theft. Overall, the U3 Smart Drive is the smart way to go.
What is a 15 pin video connection?
A '15 pin vdieo connector' has various names, including "RGB connector, D-Sub 15, mini sub D15, mini D15 and VGA Connector" There are 3 rows of 5 pins, and they are normally blue. It was the standard output from video cards from about the late 1990s till now. While some video cards from 2002 onward only have 1 or 2 DVI (Digital Visual Interface) connectors, DVI to VGA D15 connectors are common.

How do I Reset Toshiba Satellite A55 laptop to the day of purchase?
The laptop should have come with a DVD, labeled as the "Toshiba Recovery Disc." Place this disc in your DVD drive and restart your computer. OR IF YOU DO NOT HAVE THE DISK/S just go to ezrestorepc.com for all your recovery needs from many different brands including the toshiba one :-)

What are the four basic steps of troubleshooting a modem?
Step 1 - Analyze the circuit
First, see if the circuit operates correctly. If the circuit operates correctly, there is no need to troubleshoot and this would be the last step. If the circuit does NOT operate correctly, then you must go to the next step.
Step 2 - Check the setup
If the circuit is not operating correctly, check to see if you have overlooked something simple. Check connections and buttons to see if they are set correctly. If you checked the setup and the setup is good, but the the circuit does not operate correctly, go on to step 3.
Step 3 - Calculate and measure values
First, calculate to determine the values that should be present in the circuit that is not working properly by using I = V/R. Make voltage, current or resistance measurements. In most cases, the voltage measurements are made first. Voltage measurements provide useful information about the circuit and are made without breaking the circuit. If more information is needed, make current or resistance measurements. Remember, the circuit MUST be broken to make these measurements. Make as many measurements as needed. As the pieces of the puzzle begin to fall into place, identifying the fault becomes easier.
Step 4 - Check the results
Compare the calculated to measured values. You should have enough information to identify the fault. Replace the faulted component and perform step 1 again. If the circuit operates properly, the circuit is fixed.

What is 15.0 GB available HD space?
A gigabyte is equal to exactly 1024 Megabytes. So basically a Harddrive is the part of a computer where the data is stored (for example: Music, Photos, Videos, etc.) With 15 Gigabytes of disk space you can store about maybe 5 movies or 20 videos or 2,200 text files on your computer and keep them saved. So if you need to store more than that if you are using a mac and have FileVault on you can turn it off and have a lot more Harddrive space by going to: Apple >System Preferences >Security >FileVault >Turn Off FileVault...
Are only non coring needles to be used on implanted ports?
Yes, a non-coring (Huber) needle is the only type of needle that would be or should be used to access a port. the needle is hollow inside and does not remove the flesh that it passes thru when pushed thru the skin. Otherwise the skin plug would block the flow of fluids and regardless you don't want to remove any skin or any portion of the septum (plastic lid of the port) that the needle passes thru.
Are symbols and pictures examples of input or output devices?
no but the key board used to type letters is an input device , the mouse used to select symbols and the scanner used to store digital information of pictures are input devices
Do you need a cmos battery for your computer to boot?
Most new computers can automatically determine the correct settings needed for your hardware, and some even store configuration data in a non-volatile Flash chip. These computers effectively do not need a CMOS battery for anything except maintaining the correct time.
Older computers, where you had to specify the parameters for the hard drive in the BIOS, need a CMOS battery. Otherwise, you would have to enter them in every time you booted the computer.
interrupt is a disturbance ,and request to do various jobs unusually while executed to be in current process in a system
How many watts are the power supply?
Well it all depends on how high-end your computer is. If it is a rather basic model there are probably between 450 and 500 watts, but if you have a higher-end computer, it will probably have between 600 and 850 watts. This way the higher the ammount of watts your computer has the more power it will have to run the hardware of your computer.
