SELECT DISTINCT table_name
FROM information_schema.columns
WHERE column_name = 'eno'

I am working on a Database Management Systems assignment and have been unable to find a way to display the name and datatype of every column in a specific table. I don't know if this is needed but here is the link to the schema I am using for this assignment.

The employee table is what I am trying to display from.
To list all columns for a specific table:
select column_name, data_type
from all_tab_columns
where table_name = 'EMPLOYEES';
More details in the manual: http://docs.oracle.com/cd/E11882_01/server.112/e25513/statviews_2103.htm#I1020277
If you are using SQL*Plus you can simply run
desc EMPLOYEES
instead.
Most other SQL clients have a similar feature.
