The End Of the world
Browsing
As we all know, a system containing many elements is expected to be more vulnerable, since each element can contain (or be a part of) a security hole, just as a house that has many windows is potentially less secure. With time, web pages become more and more interactive. At first there was JavaScript, a language that made it possible for web pages to think, to validate information, to create cookies and pop-up windows. Then came downloadable ActiveX components that have even more control over pages and computers. then browsing becomes more secure.
Graphics Card
A video card, also known as a graphics accelerator card, display adapter, or graphics card, is a hardware component whose function is to generate and output images to a display. It operates on similar principles as a sound card or other peripheral devices.
The term is usually used to refer to a separate, dedicated expansion card that is plugged into a slot on the computer's motherboard, as opposed to a graphics controller integrated into the motherboard chipset. An integrated graphics controller may be referred to as an "integrated graphics processor" (IGP).
Some video cards offer added functions, such as video capture, TV tuner adapter, MPEG-2 and MPEG-4 decoding, FireWire, mouse, light pen, and joystick connectors, or even the ability to connect multiple monitors.
A common misconception regarding video cards is that they are strictly used for video games. Video cards instead have a much broader range of capability. Being specialized for video, output video cards improve what a computer monitor displays. As well, they play a very important role for graphic designers and 3D animators, who tend to require optimum displays for their work as well as faster rendering in order to efficiently tone up their work.
Video cards are not used exclusively in IBM type PCs; they have been used in devices such as Commodore Amiga (connected by the slots Zorro II and Zorro III), Apple II, Apple Macintosh, Atari Mega ST/TT (attached to the MegaBus or VME interface), Spectravideo SVI-328, MSX, and in video game consoles.
