Advancement in Computer Technology by Saad Shamim
5 years ago we gathered around and marveled at the little specs moving at our commands, doing not much – except moving off course, we called these things games. Today the hardware in computers and other devices has changed significantly; we went from having a “spacious” 1mb hard drive to 250 GB... What we can expect to see is an improvement in our Text-to-speech and vise versa programs after the 64bit sound card is released allowing the computer to understand our voices much clearly, also we should soon be seeing more “dept” in our computer as you may know that the most our computers can...

DVD RAM by Ken Marlborough
DVD is a format to store optical data. It is used as a storage medium for movies with very high video and sound quality. The DVD RAM or the DVD Read-And-Write Memory is a disk specification. The DVD Forum came up with it in 1996 and since 1998, DVD RAM has been used in computers, camcorders and... Though the optical drives shipped with the current Apple Macintosh computers do not support DVD RAM functions, a third party DVD RAM-compatible drive can be connected and used directly with Mac OS. ... The DVD RAM 2.0 is a single-sided, one layer disk with a capacity of 4.7 GB.

I-RAM, M-RAM: Good Bye to Hard Drives? by Marcelo Reyes
A couple of weeks ago, one of my lab associates made a comment about the advantages of the I-RAM and its speed with respect to the hard drive. What is an I-RAM? I asked. Simple. They are a bank of DDR memories that are used as a hard drive. They are powered through a PCI port and use a SATA... The way an MRAM works is based on the implementation of bits as minuscule magnetic fields that are generated on the intersections of a grid of “tracks” in dimensions measured in the nanometer range. ... Well, considering that we had to upgrade one of the computers in our lab, we recently purchased...

What Is Random Access Memory by Park Oskar
RAM is considered volatile storage because as soon as the power supply is stopped, the contents of RAM are lost. Hence, the data in RAM stays as long as the computer is running. RAM is much faster to read from and write to, when compared to other storage devices like hard disk, CDROM, Floppy... There are two fundamental types of RAM: (a) Dynamic RAM (DRAM) (b) Static RAM (SRAM) (a) Dynamic RAM (DRAM): Dynamic random access memory is the most common kind of RAM, which stores each bit of a data in a separate capacitor and a transistor.
