The main differences between Internal and external fragmentation are as below:
Computer Engineering Dictionary

Processing methods are techniques used to process/ sort different types of data. There are a number of processing methods depending upon the hardware / software capabilities of the computer and type of data need to be processed by the organization.
C pre processor (.cpp) directive of C/C++ programming language refer to a separate program which will be invoked by the compiler as first part of translation. All preprocessor are included in the program before its compilation.
Types of file organization are sequential file access, direct access and .... Pros and Cons of each file organization system
A storage class refers to the scope of data in a program. Scope of data means the portion of the program in which the variable is valid (main() as well as sub programs) and lifetime of the variable.i.e., the length of time to which the variable retains its value.
A key is an attribute or a set of attributes in a relation that identifies a tuple in a relation. The keys are defined in a table to access or sequence the stored data quickly and smoothly. They are also used to create relationship between different tables.

Anomalies: Anomalies are problems that can occur in poorly planned, un-normalized databases where all the data is stored in one table (a flat-file database).
Normalization is the process of splitting a relation (table) into sub relations or sub tables. Normalization is used to avoid or eliminate the three types of anomalies (insertion, deletion and update anomalies) which a database may suffer from.
