i. Mutability: It is the ability of a computer memory to read and write storage and comes in
the form of immutable and mutable memory types. Mutable storage can be overwritten
more than once and it is used for both secondary and primary storage e.g. ROM
ii. Accessibility: Found in both random access forms and sequential forms, hr random
access storage can be accessed in any location in about the same amount of time.
Sequential memory is slower and information is gathered and accessed in serial order.
Usually this type may be seen commonly with offline storage
iii. Addressability: This has three forms which are location, file and content. Location is
done by numerical memory address usually limited to primary storage and accessed
internally. File is done by file names with human readability. Content addressability
concerns itself with a selected hash value a short identifier with a number that point to the
memory, address for information
iv. Volatility: This is the frequency with which records are added to the file or deleted from
it. If the frequency is high, the file, is said to'be volatile. A file that is not altered is
“static”. If frequency is low, the file is said to be “semi-static”.
