A networking hardware, communication and cabling standard, originally developed by Xerox Corporation, that can link upto 1,024 nodes in a bus network. A high speed standard using a baseband (single channel) communication technique. Ethernet provides for raw data transfer rate of 10 megabits per second (MBPS), with actual throughput in the range of 2 to 3 megabits per second. Ethernet used carrier sense multiple access with collision detection (CSMA/CD) techniques to prevent network failures when two devices try to access the network at the same time.
2. EPROM (Erasable programmable read-only memory)
It is a type of memory chip that retains its data when its power supply is switched off. Computer memory that can retrieve stored data after a power supply has been turned off and back on is called non-volatile. It is an array of floating-gate transistors individually programmed by an electronic device that supplies higher voltages than those normally used in digital circuits. EPROMs are easily recognizable by the transparent fused quartz window in the top of the package, through which the silicon chip is visible, and which permits exposure to ultraviolet light during erasing.
3. EDI (Electronic Data Interchange)
Use of computers· and data communications to transmit data electronically between companies.
4. EDP (Electronic Data Processing)
Pertaining to data processing equipment that is predominantly electronic such as an electronic digital computer.
5. EFT (Electronic Funds Transfer)
Refers to a cashless approach of paying for goods and services. Electronic messages are exchanged between computers to adjust the accounts of the parties involved in a transaction.
6. EPIC (Explicitly Parallel Instruction Computing)
A technology that is fast emerging as the technology for next-generation processors. Three key features used in this technology for improved processor performance are explicit parallelism, predication, and speculation.
7. EBCDIC (Extended Binary Coded Decimal Interchange Code)
An 8-bit coding system, developed by IBM, which is used to represent characters in many computers.
8. EISA (Extended Industry Standard Architecture)
An extension to the ISA standard having extra address and database connectors compatible with the earlier ISA architecture. Introduced in 1988 by a group of nine major companies in the PC industry being:- AST Research, Compaq, Epson, Hewlett Packard, NEC, Olivetti, Tandy, Wyse, Zenith.
Encryption is the process of converting data into “ unreadable code” so that prying eyes cannot understand the content. Encryption is necessary as valuable and sensitive information is often sent from one computer to another via a network that technically can be accessed by anybody. It provides a degree of security should the information fall into the wrong hands.
