Eterlogic

Is a term used with respect to computers when a drive is emulated in some fashion. The drive being emulated could be a hard drive, floppy drive, CD/DVD or a network share among others.A virtual hard drive can be created from RAM for fast read/write access. See: RAM disk. As well, there is software that makes one's Gmail account act as a virtual external drive.

In cryptography, encryption is the process of obscuring information to make it unreadable without special knowledge, sometimes referred to as scrambling. Encryption has been used to protect communications for centuries, but only organizations and individuals with an extraordinary need for secrecy had made use of it. In the mid-1970s, strong encryption emerged from the sole preserve of secretive government agencies into the public domain, and is now used in protecting widely-used systems, such as Internet e-commerce, mobile telephone networks and bank automatic teller machines. Encryption can be used to ensure secrecy, but other techniques are still needed to make communications secure, particularly to verify the integrity and authenticity of a message; for example, a message authentication code (MAC) or digital signatures. Another consideration is protection against traffic analysis.

GOST 28147-89 is a Soviet and Russian government standard symmetric key block cipher. Developed in the 1970s, the standard had been marked "Top Secret" and then downgraded to "Secret" in 1990. Shortly after the dissolution of the USSR, it has been declassified and released to the public. GOST 28147 was a Soviet alternative to the United States standard algorithm, DES. Thus, the two are very similar in structure. In cryptography, this standard is commonly referred to as just GOST

RAM-Disk, Ramdisk or Ramdrive is a virtual solid state disk that uses a segment of active computer memory, RAM, as secondary storage, a role typically filled by hard drives. Access times are greatly improved, because RAM can be several orders of magnitude faster than hard drives. However, the volatility of RAM means that data will be lost if power is lost, e.g. when the computer is turned off. RAM disks can be used to store temporary data or hold uncompressed programs for short periods.

In cryptography, the Advanced Encryption Standard (AES), also known as Rijndael, is a block cipher adopted as an encryption standard by the U.S. government. It is expected to be used worldwide and analyzed extensively, as was the case with its predecessor, the Data Encryption Standard (DES). AES was announced by National Institute of Standards and Technology (NIST) as U.S. FIPS PUB 197 (FIPS 197) in November 26, 2001 after a 5-year standardization process (see Advanced Encryption Standard process for more details). It became effective as a standard May 26, 2002. As of 2006, AES is one of the most popular algorithms used in symmetric key cryptography.
