Definition

The degree of sharpness and clarity of an image. Resolution is expressed in pixels. Frequent computer screen resolutions are 640 x 480 pixels (VGA resolution; appropriate for a 14-inch screen), 800 x 600 (appropriate for a 15-inch screen), 1024 by 768 (appropriate for a 17-inch screen), and 1280 by 1024. LCD displays usually use a higher resolution than a CRT of the same size.

RGB stands for Red, Green, Blue. A cable that requires separate transmission types for the three colours on the display.

Synchronous DRAM is a kind of dynamic random access memory running at a much higher clock speed than regular memory.

Short for Safety Extra Low Voltage. A secondary circuit which is so designed and protected that its voltages do not exceed a safe value under normal operating conditions.

The amount of RAM that is available on your computer when you purchase it.

A recovery process that enables you to recover the hard disk image initially available on the computer. Performing a system recovery is useful in the event of a serious system crash or if you want to modify the size of your partitions.

CD-ROM that is supplied with your computer and that enables a VAIO computer user to recover the hard disk image that was available when the computer was purchased.

Short for Thin Film Transistor. Top-of-the-range notebook display for excellent picture quality. The TFT technology offers the sharpest resolution for flat displays; each pixel is supported by one to four transistors.

Short for Telecommunications Network Voltage. A secondary circuit that, under normal operating conditions, carries telecommunication signals. A typical TNV-circuit is a PSTN (Public Switched Telephone Network) modem.
