Later editions divided disks drives into group of adjacent cylinders called cylinder groups, in which each cylinder group contains inodes and their corresponding data. How does … |
| | My understand is in generic programming you can have multiple containers, which use iterators but use the same algorithm. Wouldn't template be considered a ADT? Really confused.  |
