Common important computer English and Its abbreviations

 

PC: personal computer, personal computer, or microcomputer.

NC: network computer.

PC: multimedia personal computer, multimedia PC.

MMX: Short for multimedia extensions (multimedia extensions), is an important feature of the sixth generation of CPU chips. MMX technology is added to the CPU with 57 commands specially designed for video signals (video signal), audio signals (audio signal), and image processing (graphical manipulation). Therefore, the mmx cpu greatly improves the computer's multimedia processing functions (such as stereo, video, and 3D animation.

Intel Pentium 166 MHz MMXTM: Intel Pentium is a Pentium CPU produced by Intel. Indicates "registered" (registered trademark ). The 166mhz refers to the CPU clock frequency. The MHz is the abbreviation of mega Hertz. TM in MMXTM is short for "trade mark", meaning "Registered Trademark ".

Oop: Object Oriented Programming, object-oriented programming. The so-called "object" is a collection of one or more data and the methods and processes used to process the data. Object-Oriented Programming is completely different from traditional process-oriented programming. It greatly reduces the difficulty of software development and makes programming as simple as building blocks, it is an unstoppable trend in today's computer programming.

28vga: 28 refers to the distance between the yellow optical outlets (DOT distance) on the Color Monitor. The smaller the dot distance, the more delicate the image, the better, this is because every image point on the color screen is made up of a set of red, green, and blue light. Because the technology of three beams of light cannot converge on one point by 100%, therefore, an interval of the yellow dot is generated. The smaller the interval, the clearer the image displayed on the screen. VGA is short for video graphics array.

Fat: Allocation Table, a file allocation table, which records information about how files are distributed and stored in different sectors on the hard disk.

EPA: Short for Environmental Protection Agency. In 1992, the EPA announced the Energy Star program and received a positive response from the international community. As long as you start your computer, you will be able to see the Energy Star icon on the screen in a few seconds. The goal of Energy Star is to automatically enter a low-power state when all components of the computer system do not move. When the initiative of components recovers (that is, when the keyboard and mouse are used, the computer system automatically returns to a completely awake state. For products that comply with Energy Star specifications, the EPA will send the Energy Star logo "EPA pollution preventer", meaning "pollution-proof energy-saving products recognized by the U.S. Environmental Protection Agency ".

IC Card: intelligent card, smart card.

ATX: A new specification for computer chassis, motherboard, and power supply.

IDE: Integrated Circuit device or smart disk device.

DLL: Dynamic Link Library, dynamic link library.

KB: kilo byte. KB indicates kilobytes. K = kilo, which is a word-building component, indicating "thousands; kilometers; kilograms; kilometers ". B = byte, meaning "Byte", is the minimum storage unit in the computer (one byte can store one English letter, each two bytes can store one Chinese character ).

MB: mega byte. MB indicates MB. M = mega, which is a word-building component, indicating "megabytes; millions ".

GB: giga byte. GB indicates Gigabit bytes. G = giga, which is a word-building component. It indicates Gigabit and one billion ".

Cai: computer-asisted instruction or computer-aided instruction. It will be the most important and popular teaching method in the 21st century.

Cad: computer-aided design, computer-aided design.

ISO: International Standard Organization, International Standardization Organization. ISO released the ISO 1987 series of international standards on quality management and quality assurance in 9000 and revised standards in 1994. Among them, the main standards that constitute the ISO 9000 series standards are: 1.iso 9000-1: 1994 Quality Management and Quality Assurance Standards-Part 1: selection and use guide. 2. ISO 9001: 1994 Quality System-quality assurance model for design, development, production, installation and service 3. ISO 9002: 1994 Quality System-quality assurance model for final inspection and testing.

3DS or 3D Studio: Three Dimension studio, 3D photography room. It is a set of multi-functional 3D animation software launched by Autodesk, which integrates entity modeling, static coloring, and animation creation, and greatly popularized 3D modeling technology. It can exchange graphic information with AutoCAD, and uses the scanner to input graphics to output animations to TVs or video tapes through VGA and TV conversion interfaces.

Vr: virtual reality, a virtual reality, also known as 3D input, evolved from an Air Force Simulated flight device. It basically uses the principle of switching between left and right visual spaces to display images to produce three-dimensional effects, in fact, beyond the scope of image processing, it is a computer environment that integrates light, sound, and images. People can perform interactive operations on objects in virtual environments as they do in real life, VR has broad application prospects.

OCR: optical character recognition (Optical Character Recognition) refers to the process of recognizing text materials as computer image files by means of scanner input as Chinese or English internal codes by software. Due to the randomness of handwriting, OCR is mainly limited to recognition of printed text. At present, the highest level of recognition accuracy of Chinese OCR is the TH-OCR NT for Windows.

SCSI: Small computer system interface, a small computer system interface. It is used to solve the connection problem between many external devices and computers.

OEM: original equipment manufacturer, manufacturer of original equipment.

Microsoft OEM: Microsoft OEM products. It is a software operating system pre-installed on a microcomputer, including windows98, Windows NT, workstation, windows3.x, and MS-dos.

MIS: management information system, management information system. It is widely used in all walks of life. The most famous Management Information Systems in China include "Wang TMIS", "mis", and "quick mis ".

PNP: Plug and Play, plug-and-play, is an important technical feature of window98. Plug-and-play refers to the technology that automatically sets the system structure when the operating system installs peripheral devices such as PC plug-in cards that comply with the PNP standard to the computer. This means that when you install new hardware, you do not have to set any jumper switches or use software to configure interrupt requests (IRQ), memory addresses, or direct memory access (DMA) channel. Windows 98 notifies the application of new hardware changes and automatically coordinates conflicts between IRQ, memory address, and DMA channel.

Ole: Object Linking and Embedding, object connection and embedding, or OLE technology for short. Ole not only integrates desktop applications, but also defines and implements a mechanism that allows applications to be "connected" to each other as software "objects" (functions for integrating datasets and operating data, this connection mechanism and protocol is called the Component Object Model (COM. Ole can be used to create a composite document. A composite document contains different types of data that are created in different source applications. Therefore, it can combine texts, sounds, images, tables, and so on.

MIDI: Musical Instrument Digital Interface. It is one of the basic terminologies of multimedia. a MIDI file is played and recorded by an electronic instrument, such as the keyboard, guitar, and saxophone. It can be played on most audio cards of multimedia computers, even if you do not create your own MIDI file, you can use the existing MIDI file as the background music for Multimedia demonstration. The MIDI file stores only the description of the sound, and relies on the Sound Card synthesizer (FM or waveform table) to generate the real sound that people want to listen.

MPEG: the abbreviation of Motion Picture Experts Group, that is, "Motion Image Expert Group". It is a compression encoding standard for active images and their companion sounds in multimedia computers, this is generally referred to as the MPEG standard. It consists of three parts: MPEG audio, MPEG video, and MPEG system.
