只是为了澄清@Potatoswatter 关于段的问题:
在磁盘驱动器中,这些称为(磁道)扇区。通常为 4096 字节 (4 KB) 大小,称为高级格式。
在内存中,段(或部分)是主内存的划分部分。然后,对内存位置的引用可以分解为:段 ID、段偏移量。
Just to clarify @Potatoswatter regarding segments:
In disk drives these are called (track) sectors. Typically 4096-byte (4 KB) size, known as the Advanced Format.
In memory, segments (or sections) are divided parts of the primary memory. References to memory locations can then be broken down into: segment id, segment offset.
分区是分区映射中描述的存储设备的划分,其可以包含卷。卷由包含文件系统的字节组成。
未分区的设备(例如软盘)包含卷但不包含分区。
我从来没有听说过“段”。 Google 给出了 http://evms.sourceforge.net/terminology.html,将其定义为任何逻辑上连续的扇区范围。
A partition is a division of a storage device described in the partition map, which may contain a volume. A volume comprises the bytes that contain a filesystem.
An unpartitioned device, such as a floppy, contains a volume but does not contain a partition.
I've never heard of "segment." Google gives http://evms.sourceforge.net/terminology.html, which defines that as any logically contiguous range of sectors.
