Which type port gives the best output a composite out port or an S-video port?
S-video is better than the composite video when output to a television
When computer freezes what does that mean?
Low on system memory. or a driver and a software conflict.
What function key is pressed that starts the PC Recovery Manager during boot?
Every Desktop or laptop make has it's own function key for restoring it to the original state. (ie) Acer ALT+F10.
Plc's are used for a variety of applications. Namely automation and machine industries as it is cost effective, time effective and a much more reliable source of "computer" than the traditional relay controllers. They are capable of withstanding harsh environments such as heat, cold, moist areas. Programmable Logic Controllers are obviously programmable to carry out certain program executions using 'ladder logic' in order to activate certain outputs when the condition are met with the inputs.

'Programmed Logic Controllers' keep the cost of cabling down and simplify interlocks and logic control.
A complex control panel, can control a complex system and the only things connecting them, will be a power supply line and a small data cable.
Heavy duty power cables can be kept short and local to the machinery being controlled. The switches and indicator lamps only deal with minute control signals. The function is passed to a local PLC receiver via a small data cable.
Instead of a complex system of relays and wiring, interlocks are controlled by a computer program, which enables changes to be made without re-wiring.
For example, certain pump motors can only be started when the correct valves are open. This can be dealt with by a program instead of physical wiring.
By default C: is the active partition of the hard disk drive
What will happen if there is no CPU fan in the motherboard?
The CPU will overheat (safety shutdown usually happens at around 69 degrees C), and you will be unable to use the computer for prolonged periods unless it is running with less than 50% CPU usage in a very cool environment. Side effects of constant CPU overheat can include the capacitors blowing on the motherboard if they are near the CPU heatsink.
The BIOS (Basic Input/Output System) is firmware embedded on a computer's motherboard that initializes hardware during the booting process and provides runtime services for operating systems and programs. It performs a Power-On Self Test (POST) to check hardware components and loads the bootloader from a designated storage device to start the operating system. The BIOS interface typically features a text-based menu that allows users to configure hardware settings, manage boot devices, and enable or disable system components. With the advent of UEFI (Unified Extensible Firmware Interface), modern BIOS systems have become more graphical and user-friendly, supporting larger storage devices and enhanced security features.
How does one install a new PCI video card?
To install a new PCI video card one must first turn off their computer. Taking the tower of the computer and unscrewing it. Than finding the motherboard and placing the PCI video card into the motherboard, into the slot that is made for it. Than screw the tower back together and turn on the computer.
What is the function of computer chassis?
It houses the motherboard, hard drives, power supply unit and other components.
Does a Dell dimension 4600 have bluetooth?
its possible if you buy one at the store. idk yet if theres a downloadable software for you to be able to get it, but other than that, it doesnt come with a bluetooth device frequency.
How do you determine the type of CPU in your system?
If I am answering your question correctly, to find out what CPU you are using, just go to 'My Computer' and on the left side of the window, there should be a tab that says 'About My Computer' or something like that. That is just XP, i dont know about Vista or Windows 7. If your on mac go to the apple and click about this mac and it will tell you what is in your system.
What is the use of a computer scanner?
A scanner is used to input paper documents or photos into the computer. They are typically "scanned" as images (like pictures) and stored in TIFF, GIF, or JPG format, and can also be scanned into the Portable Document Format (PDF), or converted to text using Optical Character Recognition (OCR).
How can you use SD cards on your PC?
You can either buy a printer, scanner or other external device that has an SD slot in it, buy an SD interface card that occupies a bay in the computer enclosure or you can buy an SD adapter that plugs directly into a USB port.
What is the most expensive computer monitor?
I'd say the Eizo 30". It comes with it's own calibrator and stand. The resolution on it is good enough to use it for x rays. That wraparound alienware one is pretty pricey too, but it doesn't have as much y res as the Eizo.
Projectors wise, there's a 4000 pixel projector that Audi use which would be more expensive again.

Which three device are considered output device?
An output device is all the devices used to view or obtain information from the computer.
The main typical output devices are:
monitors
speakers
web cams
printers
scanners
keyboard
mouse
light pen
digital cameras
These are the most commonly used output devices.
hope this info helped you guys a bit. good luck :)
Fuctions of input output module?
input and output devices provide a means of communcation between the computer and the outside world.
How do you record live tv programme of cable network or setup box to CD without tv tuner?
You must have a video capture card in your PC. A card that will take the signal from your TV settop box (video & audio) and record it on your hard disk. Once on your hard disk, then you can burn it to DVD or CD. You also need a capture software to do that. The software can either come with the capture card or you can buy/download a software from other companies like adobe , roxio, or Nero.
What could cause a motherboard to short circuit?
What you could be experiencing is is a short from the bottom part of the motherboard and one of the screws standoff in the computer case. First remove the mother board and notice all of the screws holes and examine the reverse side of the motherboard for scratches around these holes. if you find any use an insulator ( plastic or cardboard washer) on the underside of the hole where it meets the case srews stand-offs. Also check for screws already in place in these stand-offs that might be shorting the motherboard.
What is the Differences between laptop and desktop power supply?
There can be differences in the main power connectors to the board - e.g not the standard 24 and 4 or 20 and 4, the voltages produced are the same but the amps can be higher. Also the server may have more peripheral connectors in order to power multiple hard drives etc. My fujitsu is a low profile rack mounted server and it's PSUs are hot swap-able and don't cross over to other desktop machines. They just slot in and out without having to disconnect any cables. It's 6 SCSI hot swap hard drives are all powered from two peripheral power connectors connected to a common board. But the a tower case IBM server that I have has 6 peripheral connectors and non standard main power connectors. So there are minor and major differences depending on the server. So you need to look very carefully at the specs and what you want it to do.

How do you connect to free wireless hot spots with laptop?
When you go somewhere that has a wireless connection it will say, "Wireless connection detected". You will have to go and click the button that showed this message to chose that wireless connection and connect to it.
