A subroutine is a group of instructions written to perform a specific task. It can be called from different parts of a program using the CALL instruction, and after execution it returns to the main program using the RET instruction.
CALL 2500H ; Call subroutine at address 2500H ...
2500H: INR A ; Increment accumulator RET ; Return to main program
CALL 2500H transfers control to address 2500H.
The instructions at 2500H are executed.
RET returns control to the instruction immediately after CALL.

Grinding Process, Grinding Wheel & Wheel Wear
Grinding Process:
Grinding is a material removal process in which a rotating wheel with abrasive particles removes material from the workpiece surface. Key elements involved: (1) Grinding wheel, (2) Workpiece, (3) Relative motion between tool and workpiece, (4) Coolant to reduce heat. The grinding wheel rotates at high speed; abrasive particles present on it act as tiny cutting tools, each removing a small amount of material from the workpiece.

Navesti i kratko opisati osobine dobro projektovanog softvera. Vrlo je teško definisati šta je dobar projekat. To često zavisi od prioriteta firme koja razvija SW i od prioriteta korisnika (visoka pouzdanost, najkraće vreme, lakoća implementacije...). Osobine dobro projektovanog softvera su: 1) Hijerarhija - dobar projekat bi trebalo da bude organizovan u dobro projektovanu hijerarhiju komponenata. 2) Modularnost - treba izvršiti dekompoziciju sistema u posebne celine tj. module (na primer,
