What was the manual process of loading programs into early computers like?

• Programmers directly input code into the computer

• Programs were automatically loaded by the computer

• Programs were loaded through a network connection

• Programmers wrote code on punch cards and handed them to computer operators

What was the main issue faced by programmers when computers became more widespread?

• Configurations of computers were not always identical

• Computers were too slow to run programs

• Peripherals were not compatible with computers

• Programmers lacked the necessary skills

What is the purpose of device drivers in an operating system?

• To create virtual memory

• To control the CPU processing speed

• To manage memory allocation

• To allow programmers to communicate with hardware peripherals

What feature of operating systems allows multiple programs to run simultaneously on a single CPU?

• Time-sharing

• Batch processing
