The Internal fragmentation signifies to the result of reserving a piece of space without ever intending to use it. This space is wasted that this seems foolish it is often accepted in return for increased simplicity or efficiency.
For instance in several file systems, files for all the time start at the beginning of a sector, for the reason that this simplifies organization and makes it easier to grow files. Any space left over among the last byte of the file and the first byte of the next sector is internal fragmentation. Likewise a program which allocates a single byte of data is often allocated several additional bytes for metadata and alignment. This extra space is as well internal fragmentation.
Another common instance Letters are often stored in 8-bit bytes even although in standard ASCII strings the 8th bit of every byte is always zero and the "wasted" bits are internal fragmentation.
Same problems with leaving reserved resources unused appear in many other areas. For instance IP addresses are able to only be reserved in blocks of certain sizes, resulting in several IPs that are reserved however not actively used and this is contributing to the IPv4 address shortage
Unlike other kinds of fragmentation, internal fragmentation is most difficult to reclaim; typically the best way to remove it is with a design change. For instance in dynamic memory allocation and memory pools drastically cut internal fragmentation by spreading the space overhead over a larger number of objects.
