System software (OS, drivers, utilities) manages hardware and other programs. Application software (Word, browser, games) does user tasks. Applications need an OS. Example pair: Windows + MS Excel.
A compiler translates a whole high-level program into machine code before running. An interpreter translates and runs line by line. Compilers often catch many errors in one pass; interpreters are handy for learning and scripts.
A driver is system software that lets the OS control a specific device, such as a model of printer or webcam. After connecting new hardware the lab may need the correct driver. Without it the device may be invisible or limited.
Programs for user jobs: MS Word, Excel, PowerPoint, a browser, a painting tool, Tux typing, a school ERP. They cannot boot the machine alone. Choose legal copies.
An algorithm is a finite clear sequence of steps. Step 1: read A, B, C. Step 2: set Max = A. Step 3: if B > Max then Max = B. Step 4: if C > Max then Max = C. Step 5: print Max. Then a program can follow it.
