Plug and Play Resource Allocation
By Stephen Bucaro
Your computer has many devices connected to it. Your keyboard is a device. Your
mouse is a device. Your modem is a device. Even a port, like a USB port, is a device.
You can add a device to your computer by installing it into an expansion connector
on the the motherboard of the computer. In order to operate, resources need to be
allocated to the device.
One of the most important resources a device needs is an Interrupt Request (IRQ) line.
An IRQ signals the processor that the device needs attention. For example, each time
you press a key on your keyboard, an IRQ is sent to let the processor know that the
keyboard needs attention. A device also needs to be allocated a set of memory addresses
where commands can be sent to it and it can send responses.
Many devices need to be allocated an area of memory to store data and/or a Direct
Memory Access (DMA) channel. A DMA channel allows a device to create a data stream
directly between it and the computers memory without passing through the processor.

Where Did the User Click?
By Stephen Bucaro
An image on a computer screen is made up of "pixels" (colored dots). The computer
screen itself consists of an array of pixels. The location of every pixel can
be described by a pair of digits representing its X location and its Y location.
A pixels X location is its distance in pixels from the left side of the screen.
A pixels Y location is its distance in pixels from the top the screen.
- If your screen resolution is set to 800 x 600 pixels, a pixel at the center of
your screen would be located at X=400, Y=300.
A browser window uses the same coordinate system. Let's say you open a browser
window 400 pixels by 400 pixels and center it on your screen. The location of
a pixel at the center of the browser window would be X=200, Y=200. That is,
the pixel is located 200 pixels from the left side of the browser window and
200 pixels from the top the browser window.
Because the browser window is not maximized, the browser window location and the
screen location of the pixel would not be identical. Since we said the browser
window was centered on the screen, the screen pixel location would be X=400, Y=300.
