Introduction to IBM-PC DOS 2.1
What is IBM-PC DOS 2.1?
IBM-PC DOS 2.1, released in March 1983, marked a significant evolution in personal computing. This operating system was built to enhance the capabilities of its predecessor, IBM-PC DOS 1.0, through improved features and performance. It played a crucial role in making IBM's personal computer more accessible and functional for users, paving the way for future developments in operating systems.
The Development of IBM-PC DOS 2.1
The creation of IBM-PC DOS 2.1 was spearheaded by Microsoft after IBM sought to improve their earlier DOS version. The development focused on introducing support for hard disk drives, which were becoming more common, thus enhancing the storage capabilities and overall performance of IBM PCs. This version would become foundational in PC software development, influencing various applications and usage of personal computers.
Key Features of IBM-PC DOS 2.1
Enhanced Disk Management
One of the standout features of IBM-PC DOS 2.1 was its ability to manage larger disk volumes and improve file management with support for directories. Users could now organize files more efficiently, transitioning from a single-directory environment to a multi-directory system.
Improved User Interface and Tools
This version introduced several new commands that streamlined user interaction. Enhanced utilities like FORMAT for preparing disks and DISKCOPY for duplicating disks provided users with powerful tools to manage their data effectively.
