E's Flashcards
e-ink
(electrophoretic ink)
Micro-encapsulated black and white particles, electronically manipulated to create images and text on an e-reader.
EAP
(Extensible Authentication Protocol)
Framework for negotiating authentication methods, supporting a range of authentication devices. EAP-TLS uses PKI certificates, Protected EAP (PEAP) creates a TLS-protected tunnel between the supplicant and authenticator to secure the user authentication method, and Lightweight EAP (LEAP) is a password-based mechanism used by Cisco.
EAS
(Exchange ActiveSync)
Microsoft’s synchronization protocol that enables mobile devices to connect to an Exchange Server to access mail, calendar, and contacts.
ECC
(Error Checking and Correcting [or Error Correcting Code])
System memory (RAM) with built-in error correction security. It is more expensive than normal memory and requires motherboard support. It is typically only used in servers.
EDR
(Enhanced Data Rate)
An option in the Bluetooth specification that allows faster data rates and potentially better battery life.
EIR database (IMEI…)
(Equipment Identity Register database)
A database where IMEI numbers are stored. A lost or stolen device IMEI is marked as invalid.
EMF
(Enhanced MetaFile)
When using EMF, the software application and GDI quickly produce a partial print job. Control is then released back to the user while spooling continues in the background (GDI and the print driver are called to complete the processing of the job).
EP drum
(Electrostatic Photographic drum)
The component in a laser printer that carries the electrical charge to attract toner and then to transfer the toner to the paper.
EPD
(Electronic Paper Display)
A low-power display using e-ink to create a display that mimics the look of text on paper without using a backlight or glossy surface.
EPS specification (Power…)
(Entry-level Power Supply specification)
8-pin +12 V connectors developed initially for server-class hardware.
EPT
(Extended Page Table)
The term used for SLAT extensions by Intel.
eSATA
(external Serial Advanced Technology Attachment)
An external interface for SATA connections, enabling you to connect external SATA drives to PCs.
ESD
(electrostatic discharge)
The release of a charge from a metal or plastic surface that occurs when a potential difference is formed between the charged object and an oppositely charged conductive object. This electrical discharge can damage silicon chips and computer components if they are exposed to it.
