Can you upgrade or replace graphic card on tablet PC HP Pavilion tx1250ee?
Well from what I looked at no. If you had a desktop tower it's always much easier to do. What processor do you have? If you have Intel I'm guessing you have an Intel HD 3000-5000. If that's correct then no, because that graphic card is built into the processor so no you cannot. If you have an NVIDIA or AMD it could be possibly replaced .

"API calls" have no specific question; the term APIsimply means application programming interface, and to call an API simply means to invoke a function (or subroutine) from a computer program.
Each API call is different in how it is called (e.g. does it require any parameters, and of so, which), when (e.g. can it be called at any time and under all circumstances), what it does and what it returns to the caller.
API functions serving closely related purposes are often grouped together into an API.
Take this hypothetical example: One API provides services for rounding numbers: one function of this API rounds numbers to the nearest whole number, another function that belongs to the same API rounds numbers to the nearest hundredth.
The purpose of API is unlimited. Examples of API include API to allocate, manage and return memory from a heap, API to create, manage and delete files and folders on a hard disk, API to get and set the current time, API to draw lines and other geometric shapes, etc, etc.

How can you disable an embedded component on the motherboard?
Generally, this is a very bad idea. The only instance in which I would ever do it is to disable an integrated graphics chip and use a deticated one. I have an article from EHow below.
Many computers are purchased with integrated graphics built into the motherboard. Integrated graphics are getting more powerful all the time, but a dedicated graphics card is much more powerful than graphics integrated with your motherboard, according to the Microsoft website. To get more power and performance from your computer, upgrade to a dedicated graphics card. To change to a graphics card from integrated graphics, simply install your new video card.
Instructions- 1
Turn off your system and remove all cables from the rear panel of the computer tower. Flip the switch for the power supply to the off position if your computer's power supply has a power switch. Press the power button on the disconnected computer to release any stored charge the computer still holds in its motherboard.

Align your graphics card with the motherboard's expansion slot and press it firmly down to insert the new video card. Secure your new graphics card to the rear panel of your computer with a single computer case screw to keep it in place. Connect the graphics card to your computer's power supply if your card requires an external source of power.
- 5
Replace the side panel of the computer and tighten the screws that keep the side of the computer case secure. Attach your computer cables to the rear panel of your computer case and turn your computer's power supply switch to the on position. Double-check that you have connected your monitor cable to the newly installed video card. Press the power button on the front panel of your computer to boot your system.
- 6
Turn on your computer monitor to ensure your monitor is receiving a signal from the new graphics card. Your motherboard will automatically detect that a card is plugged into the expansion slot, and use the installed graphics card for video.
- 7
Insert the driver installation disk and follow the installation media's instructions. If necessary, restart your computer to apply the new driver settings and configuration for your graphics card.

Is sensor an input or output device?
Assuming that a sensor (any type, heat, light, sound etc) is connected to something - eg a computer or a switch etc. it is an 'input' device.
The device which created whatever is being 'sensed' is an output device.
For example if you put a thermometer next to a light bulb to see how hot it is then the bulb is 'output' and the thermometer is 'input'.

Daisy chaining is when you tie up a rope a certain way for storage so that you will not damage the rope when it is not in use. You can make one by making a loop at one end of a rope, pulling a little bit of rope the the loop to form another loop, pull some rope through that rope to make another loop, and so on until the end when you pull the end of the rope completely through the last loop. If you do it right, you will be able to un-daisy chain the rope in one pull. The whole method is very convenient.

How do you connect the coaxial cable feed to the ethernet connection on the computer?
Most current networks use UTP but you are describing a "thinwire" network.
Thinwire uses coax and an Rg58 connection.
UTP (Unshielded Twisted Pair) networks use RJ45 connectors. They look like an oversized telephone plug.
You can purchase a thinwire modem for your computer if that's what you need, or you can get a hub that can act as a converter if your computer already has an RJ45 network connection.
