CompTIA HIT-001 Flashcards
802.11
A family of specification developed by the IEEE for wireless LAN technology.
802.11a
a fast, secure, but relatively expensive protocol for wireless communication. The 802.11a protocol supports speeds up to 54 Mbps in the 5 GHz frequency.
802.11b
Also called Wi-Fi, short for wired fidelity, “802.11b is probably the most common and certainly the lest expensive wireless network protocol used to transfer data among computers with wireless network cards or between a wireless computer or device and a wired LAN. The 802.11b protocol provides for an 11Mbps transfer rate in the 2.4GHz frequency.
802.11g
A specification for wireless data though put at the rate of up to 54Mbps in the 2.4GHz that is a potential replacement for 802.11b.
802.11i
A standard that adds AES security to the 802.11 standard
802.11n
A wireless standard for home and business implementations that adds QoS features and multimedia support to 802.11a and 802.11b
802.1x
An IEEE standard used to provide a port based authentication mechanism for wireless communications using the 802.11a and 802.11b protocols.

A method in which an attacker with access to the target network redirects an IP address to the MAC address of a computer that is not the intended recipient.
ARP(Address Resolution Protocol)
The mechanism by which individual hardware MAC addresses are matched to an IP address on a network.
ARRA (American Recovery and Reinvestment Act
U.S. economic stimulus legislation; provisions include funding of some healthcare initiatives and the creation of the HITECH Act.
ASP (Active Server Pages)
A server-side programing languague developed by Microsoft to provide a method to create dynamic web pages.
Assisted Living Facility
A residential facility or community for patients who may need assistance with some functions of daily living, such as bathing or medication reminders, but can otherwise remain mostly independent.

The official ANSI term for IDE drives.
Availability
The fundamental security goal of ensuring that systems operate continuously and that authorized persons can access data that they need.
