|
What did assembly language allow programmers to do? |
Assembly language let programmers write instructions using letter symbols rather than binary operation codes |
|
|
What are some advantages of assembly language compared to machine language? |
Assembly language is easier and faster to write, easier to debug, easier to change at a later date. |
|
|
What does machine oriented mean? |

|
|
What is a programming environment? |
A programming environment is a set of tools that includes an editor for entering and changing the program, a compiler or interpreter for translating programs into a machine language that the computer can understand and sometimes a debugger. |
