What is the combination of input and output devices?
If i recall, the only thing like that is a touchscreen- input is the sensor and output is the visual
What do you do after finding out that overheating is the problem in your computer system?
Note: If System is under warranty we recommend contacting your manufacturer. If not then you can try these steps to lower down the processor temperature
If your computer is overheating and it was recently built, the following tips may resolve your issue:
1. Move your computer to the coolest place of your house. You may choose to lower the temperature of the room instead by cranking up the air conditioning. Operate the computer and see if the same problem appears. If it doesn't, then that is a fair indication that the issue was due to overheating .
2. Check for dust. Remove the computer's outer cover and see if dust has built up. Dust can reduce the airflow, it can slow down the fans or other mechanical components it gets into, or it can act as an insulator causing heat to increase. Use air pressure to remove the dust.
3. Determine if you have components that are set to overwork. If you assembled the computer yourself, you may have adjusted certain components to higher settings for boosting their performance. If you have a device working at a higher voltage or higher clock cycles, lower down its setting or remove it altogether, if possible.
4. Inspect the temperature around the components that use the most power. These are, the CPU, the graphics processor, the power supply and the hard drives. Use your hand to assess the ambient temperature. It shouldn't be more than 2 degrees Celsius warmer than the room's temperature, while the computer is running. You can tape temperature sensors bought from a computer store, if unsure. Change the placement of the components or the fans to improve the airflow, if you found components blocking the air intake.
5. Buy and install a cooling fan. Choose a fan that can lower temperature of your motherboard by as much as 5 degrees Celsius.
6. Use liquid cooling as an alternative to a cooling fan.

List three basic types of cables found inside a computer case and what are their functions?
Power Cables: These are the cables that run from your PSU (Power Supply Unit) and attach to various devices in your computer, including but not limited to: the Motherboard, Hard Drive(s), Optical (CD/DVD/Blu-Ray) Drive(s), Fans, etc SATA (Serial ATA) Cables: This cable attaches to either an Optical Drive, Hard Drive, or a SATA External Port to provide a connection between the device and the motherboard and provides for the transfer of information. IDE/ATA Cables: The Predecessor to the SATA cables. They are still seen, but are fast becoming a legacy item. They provide a connection between Floppy Drive(s), Optical Drive(s), or Hard Drive(s) and the motherboard in the same fashion that a SATA Cable would, but provide a much slower speed and capacity than a SATA cable would.
A USB header is a group of pins, typically on a computer motherboard or expansion card, to which an internal USB cable can be attached to provide extra USB ports. Typically, one header is a group of two USB ports.
The most common USB header layout is:
5v, D-, D+, Gnd, NC
5v, D-, D+, Gnd, Key
Some may be in reverse order, or completely different, so caution is advised.
Manufacturers generally design USB headers on to their motherboards if they have extra USB ports left over from the design of the rear I/O. Instead of terminating these extra USB ports, they can be left as USB headers to be used by some other means.
Many computer cases feature "Front USB Ports". These front USB ports connect to the USB headers on the motherboard. This is the most common use for USB headers.
Words of Cauton: -
There are several varieties of header pin layouts ranging from 4 pin, to 10 pin, The most common ones are 5 pin for single USB header, to 9 pin for dual USB, where pin 9 and 10 are not used. Pin 9 and blank pin 10 are to ensure the plug is inserted correctly.
Some 9 pin header plugs have different places where the blank pin is and also a different wiring order. You must have the right wiring order and plug for your device, and to your motherboard, or you may do some serious damage to your PC and/or USB devices. It is wise to always double check the pins and wiring via a PC Tech before buying and installing any internal after market USB device.
a usb cable is a cable that allows the computer to communicate with the object u are connecting it to. For example there is a computer powered fan which is connected to a computer using an usb cable
How many ace hardware are there worldwide?
There are more that 5,000 Ace outlets in 60 countries worldwide.
The Egyptian civilization developed at a faster rate than its neighbors due to its access to?
The Nile River
No. VGA port is not either serial or parallel port. It is a different interface. If you need a serial output, you need a VGA to serial converter.
The fan in a 250-watt power supply is malfunctioning. what action should you take?
Remove and replace the power supply.
Is there any software to detect a output for an electric motor by giving an input?
Just a suggestion... try looking for a software programmer, Java programmer to help you. They can create program for your problem in your electric motor. but it will cost you some dollars. as long as you are willing to pay, computer programmers can help you.
Try looking for software programmers online, there's a lot of them. ok?
Hoped my suggestion helps you.
How much does a USB port cost?
For manufacturers, the cost to implement them on a motherboard is only a couple of cents. If you want to add a USB hub to your computer, they can usually be had for under $20.
Jean Andrews A plus Guide to Hardware Answer Key?
The Instructor's copy of this book/materials contains the answers. Frustrating!? I purchased a used copy from my local college for self-study, only to find out that it didn't come with answers. I also think you have to present some sort of educator's license to purchase the Instructor's version (that contains the answers). Still, I wouldn't send this book back if you already have it, but check the CompTIA Marketplace (www.comptiastore.com) for other resources.
Types of hardware equipment that needs antistatic packaging and handling precautions?
1. CPU Central Processing Unit ( The brain of the computer).
2. HDD Hard disk drive.
3.CMOS The battery.
4.VGA Card and Network Card.
5. Pc board
You're wrong noob
Through what process does UTP cable help to avoid crosstalk?
blabla
^ What the hell kind of answer is that? :P
UTP stands for Un-shielded Twisted Pair, and it is these twists that help to avoid crosstalk.
What are the features of rtlinux?
Deterministic Realtime: RTLinux™ supports realtime interrupt handlers and realtime periodic tasks with interrupt latencies and scheduling jitter close to hardware limits. RTLinux reliably give worst case interrupt latencies of less than 15 microseconds on a standard x86 PC, with better figures on single board computers and PowerPC and Compaq Alpha platforms.
Standard API:
uses a POSIX threads API and follows the POSIX 10003.13 PSE31 ``minimal realtime system model" specification. RTLinux™ runs Linux as its lowest priority thread and provides access to the full power of Linux through a variety of
communication methods
Open Source: FSMLabs RTLinux™ can be freely downloaded from the Internet. The core OS code is available under the GNU Public License
Rich toolset: All the standard tools-the GDB source level debugger, GNU compilers, Perl, TCL/TK, etc.-are available and easily interfaced with realtime code

What is 232 in RS232 and MAX232?
The difference between max232 and rs232 is the voltage levels of the rs232 are high. In order to reduce those voltage means to convert those voltage levels to TTL logic levels we use max232 integrated chip which is a dual driver/ receiver.
