Warm Boot. A warm boot restarts the mobile computer by closing all running programs. All data that is not
saved to flash memory is lost.
WEP. Wired Equivalent Privacy, is specified by IEEE for encryption and decryption of RF (wireless)
communications.
WEP Encryption. (Wired Equivalent Privacy encryption) The conversion of data into a secret code for
transmission over a public network. The original text, or plaintext, is converted into a coded equivalent called
ciphertext via an encryption algorithm. The ciphertext is decoded (decrypted) at the receiving end and
turned back into plaintext. The encryption algorithm uses a key, which is a binary number that is typically
from 40 to 128 bits in length. The greater the number of bits in the key (cipher strength), the more possible
key combinations and the longer it would take to break the code. The data is encrypted, or “locked,” by
combining the bits in the key mathematically with the data bits. At the receiving end, the key is used to
“unlock” the code and restore the original data.
Wireless Local Area Network (WLAN). See LAN.
WNMP. (Wireless Network Management Protocol) This is Symbol’s proprietary MAC layer protocol used for
inter access point communication and other MAC layer communication.
WNMS (renamed to AirBEAM® Manager). See AirBEAM® Manager.
