How can a 1GB program run in only 512MB of memory?
Through the magic of Virtual Memory, though it might page to disk more often than you want.
What will happen if you set your computer on fire?
You will get some views on youtube... and it won't work anymore (99% likely)
What produces a raster image and what produces a vector image?
raster image = monitor, laser printer or ink-jet printer
vector image = graphics plotter
Why do you need to use the CMOS setup?
It saves the passwords given in a particular computer.
It also controls how the computer responds when first switched on.
It sets the clock, determines which drive is looked at first, turns caps lock on/off, allows or denys external graphics card to be used and controls how memory is allocated.
It all depends on which manufacturer made your motherboard, some allow more functions than others.
18.5v should be fine for a 15-16v application. remember circuits will only draw the amount of current they need, no more. you could also try adding a current limiting resistor in series with the load. use a VOM for this testing (as the load).
Why is the computer case the first component you should consider when building a computer?
It isn't! The first is to determine you computer needs; Server, Business Professional, Gamer, Graphic/Video Designer or Editor, etc...
Then if you are going to use RAID, and other power constrains.
Sum total power consumption +20% and make sure Case with Power Supply wattage is sufficient.
almost all modern computers do this (the exceptions are typically simple microcontrollers ). various methods can be used:
- prefetch
- pipelining
- caches
- etc.
One computer that I used that implemented prefetch (without pipelining, caches, or other mechanisms) to an extreme was the Delco Magic V implementation of the MIL-STD-1750A architecture. It had a prefetch unit with a FIFO buffer that could store roughly 20 instructions before they were needed by the address evaluation and operand read unit which had another FIFO buffer which could store roughly 20 instructions their operands and the address to store the results to before they were needed by the execution unitwhich had yet another FIFO buffer which could store roughly 20 results and the address to store those results tobefore they were needed by the memory storage unit. In all roughly 60 instructions could be held waiting to be processed between prefetch and storage of results to memory. Multiple levels of scoreboard synchronization logic were used to prevent the prefetch unit and address evaluation and operand read unit from accessing memory or registers pending modification by the memory storage unit or execution unit.
What feature is provided by an auto-switching power supply on a laptop?
Auto switching usually refers to the input voltage being automatically selected, therefore one on a laptop probably means you can use multiple charger units with it or it selects its own mains charger voltage.
How do you enable pen pressure on your tablet in photoshop 7.0?
window, brush, open the brushes on the right, check the shape dynamics, in the same menu there should be an options window where pen pressure appears, click it, click accept or OK ... you're done!
How do you know what the inputs and outputs are in functions?
if you have the equation, choose one of the pairs and put one of them in the position of x and solve. if you get the leftover value, the one you put in the equation is the x, independant variable, the other is y
Can you go on internet using the wacom bamboo tablet?
Yes! In fact if you are like me, once you start using a tablet for everything you'll have trouble returning to the slow old mouse!
Tablets take a little time to get used to, but for most things are much faster than mice!
What is dos interrupt and bios interrupt?
There are more than one of them, the most important DOS interrupt is 21H. Consult the related link.
How much is a graphics tablet?
A graphic tablet cost around 2,000$ for a good one not a grate one. i suggest getting on on sale because they range between 2,000 to 4,000$.
What other kinds of waiting are there in an operating system?
Some other kinds of waiting in an operating system include waiting on applications, waiting on the user, and waiting for hardware to communicate. The operating system facilities many different components to work in sync.
Does your computer and tower have to match?
Your tower is your computer. If you are asking if the monitor and computer have to match the answer is no. You can use any monitor with any computer.
What are the typical contents of the BIOS startup screen?
typical MOST BIOS start ups contain
Advance BIOS Features
Advance Chipset Features
Integrated Peripherals
Power Management Setup
then under them are more options etc
What are the USB ports for on PlayStation 3?
The USB ports on the PlayStation 3 can be used for a variety of items, including (but not limited to) memory sticks or external disk drives for copying data (music, video, or photos) to or from the system, backing up the system, or saving game data; printers; charging the SIXAXIS wireless controllers; and attaching the external PS2 memory card adapter.
What are the cause of computer system restart or shut down itself?
The 'Re-Start' could be caused by a virus. Vheck out you system using Norton Anti-Virus or some other virus checking program and see if there is a bug in yours. The automatic shutdown could also be caused by a virus or it could be in your system setup under 'Power Schemes' and the thing is actually going into Hybernation or Stand-By, but from the first part of your question, you should look more at a virus as the cause.....
Which laser printer component protects a fuser from overheating?
A temperature sensor riding on the fuser roller changes resistance affecting current flow from engine control board, through sensor, back to engine control board. Debre buildup under sensor and degredation of sensor will affect normal operation. Thermal fuse only protects from possible fire starting; heating lamp/ceramic strip most always blows first. Over heating usually due to engine control board but in LJ III was due to AC power module stuck, supplying continuous 24 Volts DC to turn on lamp; this lamp always has 120VAC incase you don't unplug printer first.... If fuser heats without blowing... clean sensor within fuser assy with que tip and alcohol or replace fuser if paper being overheated first; then engine control board second.

What are some Examples of time sharing operating system?
A special case of multiprogramming in which users access the computer through terminals, typically the devices with keyboards and screens. Dozens of users share the computer at once. The computer actually does not run them all simultaneously but it runs a small portion of ones user's job then moves the service to the next user providing service to each user several times and then it appears that is is actually doing all its actions at one time but it's not. After all the requests are done they all get responses about the same time.
