Key Differences
DOS (Disk Operating System) typically refers to MS-DOS, known for its simplicity and command-line interface, primarily used in personal computing during the 1980s and 1990s. On the other hand, Unix was developed earlier and is renowned for its robust multitasking, multiuser capabilities, and widespread use in both academic and commercial environments.
DOS operates mainly on IBM PC compatible systems and uses a simple file system without built-in support for networking. Whereas Unix operates across a variety of hardware platforms and includes native support for TCP/IP networking, making it integral to the development of the internet.
DOS is mostly driven through command-line commands and batch files, offering limited multitasking capabilities. Unix, however, provides a powerful command-line interface, scripting languages, and several graphical user interfaces like GNOME and KDE.
Security in DOS is minimal with no user account management by default, which means all users have full system access. In contrast, Unix features a robust security model that includes user permissions, access controls, and encrypted passwords.
DOS does not inherently support multiple simultaneous users or processes, focusing on single-task operations. On the other hand, Unix supports concurrent users and processes, making it suitable for environments requiring multitasking.

Unix
Unix (; trademarked as UNIX) is a family of multitasking, multiuser computer operating systems that derive from the original AT&T Unix, whose development started in the 1970s at the Bell Labs research center by Ken Thompson, Dennis Ritchie, and others.Initially intended for use inside the Bell System, AT&T licensed Unix to outside parties in the late 1970s, leading to a variety of both academic and commercial Unix variants from vendors including University of California, Berkeley (BSD), Microsoft (Xenix), Sun Microsystems (SunOS/Solaris), HP/HPE (HP-UX), and IBM (AIX). In the early 1990s, AT&T sold its rights in Unix to Novell, which then sold its Unix business to the Santa Cruz Operation (SCO) in 1995.
