| comp., MS | bit block | 位块 (In computer graphics and display, a rectangular group of pixels treated as a unit. Bit blocks are so named because they are, literally, blocks of bits describing the pixels' display characteristics, such as color and intensity. Programmers use bit blocks and a technique called bit block transfer (bitblt) to display images rapidly on the screen and to animate them) |
| comp., MS | 8-bit color | 8位彩色 (A display setting that holds up to 256 specific color entries. Any color palette attached to a picture is by definition an 8-bit palette) |
| comp., MS | 128-bit encryption | 128 位加密 (A high level of encryption that uses a 128-bit key to scramble the contents of a file or data packet to make the data unreadable without the decryption key) |
| comp., MS | 40-bit encryption | 40 位加密 (A low level of encryption that uses a 40-bit key to scramble the contents of a file or data packet to make the data unreadable without the decryption key) |
| comp., MS | bit image | 位图 (" A sequential collection of bits that represents in memory an image to be displayed on the screen, particularly in systems having a graphical user interface. Each bit in a bit image corresponds to one pixel (dot) on the screen. The screen itself, for example, represents a single bit image; similarly, the dot patterns for all the characters in a font represent a bit image of the font. In a black-andwhite display each pixel is either white or black, so it can be represented by a single bit. The "pattern" of 0s and 1s in the bit image then determines the pattern of white and black dots forming an image on the screen. In a color display the corresponding description of on-screen bits is called a pixel image because more than one bit is needed to represent each pixel. ") |
| comp., MS | 32 bit machine | 32 位机器 (A computer that works with data in groups of 32 bits at a time. The Apple Macintosh II and higher models are 32-bit machines, in terms of both the word size of their microprocessors and the size of the data buses, as are computers based on the Intel 80386 and higher-level microprocessors) |
| comp., MS | 64 bit machine | 64 位机器 (A computer that works with data in groups of 64 bits at a time. A computer may be considered a 64-bit machine either because its CPU operates internally on 64-bit words or because its data bus can transfer 64 bits at a time. A 64-bit CPU thus has a word size of 64 bits, or 8 bytes; a 64-bit data bus has 64 data lines, so it ferries information through the system in sets of 64 bits at a time. Examples of 64-bit architecture include the Alpha AXP from Digital Equipment Corporation, the Ultra workstation from Sun Microsystems, Inc., and the PowerPC 620 from Motorola and IBM) |
| comp., MS | bit mask | 位掩码 (A numeric value intended for a bit-by-bit value comparison with other numeric values, typically to flag options in parameter or return values. Usually this comparison is done with bitwise logical operators, such as And and Or in Visual Basic, && and || in C++) |
| comp., MS | bit rate | 比特率 (The speed at which binary digits are transmitted) |
| comp., MS | bit-rate throttling | 比特率限制 (The ability to slow down the rate at which files can be downloaded) |
| comp., MS | bit specification | 比特规范 (The number of colors or levels of gray that can be displayed at one time. The amount or memory in the computer's graphics controller card controls the display. An 8-bit controller can display 256 colors or levels of gray; a 16-bit controller, 64,000 colors; and a 24-bit controller, 16.8 million colors) |
| comp., MS | bit stream | 位流 (In synchronous communications, a continuous flow of data in which characters in the stream are separated from one another by the receiving station rather than by markers, such as start and stop bits, inserted into the data) |
| comp., MS | bit-wise comparison | 按位比较 (A bit-by-bit comparison of identically positioned bits in two numeric expressions) |
| comp., MS | broadcast bit | 广播比特 (A one-bit field value in the flags field of the DHCP packet sent by the client to provide a hint to the DHCP server and to the relay agents to broadcast any messages sent to the client) |
| comp., MS | constant bit rate | 恒定比特率 (A characteristic of a data stream in which the bit rate remains nearly uniform for the duration of the stream) |
| comp., MS | data bit | 数据位 (In asynchronous communications, one of a group of from 5 to 8 bits that represents a single character of data for transmission. Data bits are preceded by a start bit and followed by an optional parity bit and one or more stop bits) |
| comp., MS | dirty bit | 更改位 (A bit used to mark modified data in a cache so that the modifications may be carried over to primary memory) |
| comp., MS | multiple bit rate | 多比特率 (A characteristic of a data stream in which the same content is encoded at several different bit rates in oder to optimize content delivery) |
| comp., MS | multiple bit rate encoding | 多比特率编码 (An encoding method where a single WMV file contains several streams of varying bit rates) |
| comp., MS | parity bit | 奇偶校验位 (In asynchronous communications, an extra bit used in checking for errors in groups of data bits transferred within or between computer systems. In modem-to-modem communications, a parity bit is often used to check the accuracy with which each character is transmitted) |
| comp., MS | secure bit | 安全位 (The bit in a key message used to notify the supplicant and authenticator when a key exchange is complete and a link is considered secure. The bit is set to 0 (not secure) or 1 (secure)) |
| comp., MS | variable bit rate | 可变比特率 (A characteristic of a data stream in which the bit rate fluctuates, depending upon the complexity of the data) |
