The OSI model layer that provides a user interface in the form of an entry point for software programs to access the network infrastructure is: application layer.
<h3>What is the
OSI model?</h3>
OSI model is an acronym for open systems interconnection and it comprises seven (7) main layers, which typically starts from the hardware layers (layers in hardware systems) to the software layers (layers in software systems)
<h3>The layers of the
OSI model</h3>
In Computer networking, the seven (7) layers of the OSI model include the following in sequential order;
The uppermost layer of the OSI model which is the "application layer" gives software programs an access to the services that allow internet connection or network infrastructure.

A computer network is a group of computers that use a set of common communication protocols over digital interconnections for the purpose of sharing resources located on or provided by the network nodes.
Answer:
The longest codeword that could possibly be for "n" symbol is n-1 bits.
Explanation:
From the given information:
Suppose we are to consider a set of frequencies 
, for which f is a symbol for the length n. Therefore, the longest codeword that could possibly be for "n" symbol is n-1 bits.
However, during the encoding for "n" in conjunction with n-2, then the possibilities for n are; 
We can conclude that the longest codeword that could possibly be for "n" symbol is n-1 bits.
