What is the DTD and what is it used for?
DTD stands for Document Type Definition. The DTD is most commonly used in web pages. By declaring a DTD at the top of the page, the browser is given a "Rosetta Stone" telling it how to render the page.
The use of internal markers has long existed in binary files. A GIF file, for instance, may be either the 1989 format, which allows (among other things) animation, or the original 1987 format, which was slightly smaller. Label a 1989-format GIF file with a name ending in JPG, and virtually any browser will see that the first six bytes are the ASCII characters "GIF89A" and will render it correctly.
The use of DTD allows similar behavior with ASCII files. Because the DTD is an external URL, browsers do not need to download the same information over and over, and because it's not internal to the browser, browsers are able to deal with new file formats that did not exist when the browser was initially released.
Could your computer shut down with cheat engine?
You just press the start button and then press shut down!! People these days don't do things simply!!
There are eight billion bits in a Giga byte.
Well actually there are eight bits in a single byte.
There are 1024 bytes in a kilobyte
There are 1024 kilobytes in a megabyte
There are 1024 megabytes in a Giga byte (and 1024 Gigabytes in a Terabyte etc)
So there are 8*1024*1024*1024 = 858589934592 bites in one Gigabyte.
Hard disks and other memory devices have to dedicate some of their capacity to lookup tables and adminstrative data so you can never get access to every single bit that a device has.
Modular computing is a generic philosophy that relies on "modules". These modules each have a specific function in the overall system. This is advantageous in many scenarios because it allows for modules to be re-used without re-creating them.
Modular computing is seen at both the hardware and software levels.

BD Agent......"C:\Program Files\BitDefender\Bitdefender 2009\bdagent.exe"
BitDefender Switch Agent. Startup background task whose role is to ensure that BitDefender continues to work properly and protect your PC when you have Windows XP and there are multiple users defined on your PC and Fast Switching is enabled (Fast Switching is the feature where you can switch to another user profile on your PC without first logging off the current user).
BDAgent.exe Recommendation : Down to end-user requirements. If you do not have Windows XP, then you can disable this program on the Startups tab. Ditto if you do have Windows XP but Fast Switching is not enabled or you are the only user defined on this PC. In any other scenario, leave this task enabled. Others say . If you disable it, you will not be able to see Virus alerts and Firewall questions.

Applications and "open documents" all consume memory (RAM), which is finite. When the system runs low on RAM, it can use paging (subject to the operating system and settings). Paging means to emulate larger than physical RAM with the help of a hard disk. Accessing this hard disk and the "paged memory" slows down the computer.
Apart from RAM consumption, each running application (and within each application, each process, thread or fiber (with varying terminology subject to the operating system)) consumes CPU cycles. Even if the application does nothing, the application or a related operating system services needs to check and confirm that it needs no do nothing (or take action if a keystroke, a relevant mouse movement or any other event occurs).
