 The Abstract Syntax Notation One is used to formally describe the
-semantics of data transmitted across the network. Two communicating
-parties may have different formats of their native data types (i.~e.
-number of bits in the integer type), thus it is important to have
+data transmitted across the network. Two communicating parties may employ
+different formats of their native data types (e.~g., different number
+of bits for the native integer type), thus it is important to have
 a way to describe the data in a manner which is independent from the
-particular machine's representation. The ASN.1 specifications are
-used to achieve the following:
+particular machine's representation.
+The ASN.1 specifications are used to achieve the following:
 \begin{itemize}
 \item The specification expressed in the ASN.1 notation is a formal and
-precise way to communicate the data semantics to human readers;

 \item The ASN.1 specifications may be used as input for automatic compilers
 which produce the code for some target language (C, C++, Java, etc)
-to encode and decode the data according to some encoding rules (which
-are also defined by the ASN.1 standard).
