  21. 21. Advanced Technologies  A set of Single Instruction Multiple Data (SIMD) instructions that enable fast and secure data encryption and decryption based on the Advanced Encryption Standard (AES).  IntelAES-NI are valuable for a wide range of cryptographic applications, for example: applications that perform bulk encryption/decryption, authentication, random number generation, and authenticated encryption.  AES is broadly accepted as the standard for both government and industry applications, and is widely deployed in various protocols.

Intel®Advanced Encryption Standard New Instructions (Intel®AES-NI)
  23. 23. Advanced Technologies  Allows memory to be marked as executable or non- executable, when combined with a supporting operating system. If code attempts to run in non-executable memory the processor raises an error to the operating system.This feature can prevent some classes of viruses or worms that exploit buffer overrun vulnerabilities and can thus help improve the overall security of the system.

  • Sandy Bridge is the codename for a microarchitecture developed by Intel beginning in 2005 for central processing units in computers to replace the Nehalem microarchitecture.Complementary metal–oxide–semiconductor (CMOS) is a technology for constructing integrated circuits. CMOS technology is used in microprocessors, microcontrollers, static RAM, and other digital logic circuits.“Tick-Tock" is a model adopted by chip manufacturer Intel Corporation since 2007 to follow every microarchitectural change with a die shrink of the process technology. Every "tick" is a shrinking of process technology of the previous microarchitecture and every "tock" is a new microarchitecture. Every year, there is expected to be one tick or tock.http://en.wikipedia.org/wiki/Multigate_device#Tri-gate_transistors

  • Intel recommends enabling Intel® HT Technology with Microsoft Windows 7*, Microsoft Windows Vista*, Microsoft Windows* XP Professional/Windows* XP Home* Not supported in 3550S
  • Maximum frequency is dependent on the SKU and number of active cores.
  • Hardware-level technology disables your device even if the hard drive is removed, replaced, or reformattedIntel® AT detects suspicious behavior. For example, your laptop will automatically lock down if it fails to check-in over the Internet at a pre-set time with your service provider.When your device is recovered, it can be quickly restored with your one-time password—without damage to your personal data.
