The Sony PCG 7192, part of Sony's Vaio line, combines a laptop's functionality with a desktop's high quality and durability. This means it is not tiny, but it is certainly portable, which gives it a definite edge over most desktop computer systems, particularly for those who travel with their computers often and need something with a hardy build.
The Sony PCG 7192L, like all computers, processes short-term functions with its random access memory (RAM) and its processor. The processor is a 2.2 gigahertz Intel with a 2 MB cache, and the Sony PCG 7192L comes with 4 GB of RAM installed, with the capacity for a further 2 GB more in the future. This RAM runs at 800 Mhz.
The hard drive is 320 GB -- enough for over 100 feature-length films. It spins at 5400 revolutions per minute. The DVD drive runs at 8x speed and can both read and write CDs and DVDs.
