The introduction of disk technology allowed the operating system to keep all jobs on disk rather than in a ______. Options: - Storage Area - Memory - Card Reader - Disk
Answer (1)
The correct answer to the question is Memory .
When disk technology was introduced to computing, it transformed how operating systems managed jobs. Here's a detailed explanation:
Before Disk Technology:
Prior to the development of disk storage, early computers often used devices like punched card readers for job input. In these systems, the jobs that needed to be processed had to be stored entirely in memory or read sequentially from punched cards.
Introduction of Disk Technology:
With the introduction of disk storage, it became possible to store all jobs on disks. Disk storage offered a large capacity for data and allowed random access rather than sequential access, which meant that jobs could be retrieved more flexibly and efficiently.
Role of Memory in Computing:
Even with the advent of disk storage, memory remains a critical component. It stores actively running processes and instructions that the CPU needs immediate access to. By keeping all jobs on disk rather than in memory, systems manage to better use the limited and volatile space in memory, loading jobs only as needed.
In essence, the shift meant that jobs were kept on disk storage and only loaded into memory when necessary, easing the demand on the fast but limited memory space. This advancement was pivotal in the evolution of computer operating systems and their ability to handle multiple tasks efficiently.
