Which of the following devices will not require the use of system software to operate?

An analogue camera is the only device from the options that will not require the use of system software to operate. Analogue cameras use physical mechanisms to capture and store images, without the use of digital technology or software. On the other hand, MICR, mobile phones, and OCR all use digital technology and therefore require system software to operate. MICR is a technology used for processing and storing financial transactions, while OCR stands for Optical Character Recognition, which uses software to convert scanned images of text into machine-readable text. Mobile phones also use software to run various applications and perform tasks.
