问题 单项选择题

与十六进制数BC等值的二进制是( )。

A.10111100
B.10111011
C.11001011
D.11001100

答案

参考答案:A

解析: 图形和图像文件格式分两大类:一类是静态图像文件格式,一类是动态图像文件格式。静态图像文件格式有GIF、TIF、BMP、PCX、JPG、PCD等,动态图像文件格式有AVI、MPG等。位图文件格式是Windows操作系统采用的图像文件存储格式,在Windows环境下运行的所有图像处理软件都支持这种格式。位图文件默认的文件扩展名是.BMP或.bmp。PNG是一种新兴的网络图像格式,也是目前最不失真的格式,它汲取了GIF和JPG二者的优点,存储形式丰富,兼有GIF和JPG的色彩模式。PNG格式的另一个特点是能把图像文件压缩到极限以利于网络传输,但又能保留所有与图像品质有关的信息。
WAV格式是微软公司开发的一种声音文件格式,也叫波形声音文件格式,是较早的数字音频格式之一,被Windows平台及其应用程序广泛支持。WAV格式支持多种压缩算法、音频位数、采样频率和声道,采用44.1kHz的采样频率和16位的量化位数,因此,WAV的音质与CD相差无几。但WAV格式对存储空间需求太大,不便于交流和传播。
AVI文件是Windows平台的视频文件格式,其文件扩展名为AVI。在与MPEG-2格式的文件体积差不多的情况下,AVI格式的视频质量相对而言要差不少,但制作时对计算机的配置要求不高,因此可以先录制好AVI格式的视频,再将其转换为其他格式。
