Learn about MULTICS, the groundbreaking operating system that revolutionized computing in the 1960s. Developed by MIT and Bell Labs, MULTICS was the first timesharing operating system and one of the pioneers of symmetric multiprocessing. Originally used on GE mainframes, MULTICS was eventually acquired by Bull and incorporated into the Honeywell product range.

What is MULTICS?

MULTICS stands for Service for Multiplexed Information and Computing. It was an operating system developed in the 1960s.

What made MULTICS groundbreaking?

MULTICS was not only the first timesharing operating system, but it was also one of the first to use symmetric multiprocessing.

Who developed MULTICS?

MULTICS was created by a collaboration between MIT and Bell Labs.

What mainframes was MULTICS used on?

MULTICS was originally used on GE mainframes.

What happened to MULTICS?

MULTICS was later acquired by Bull and incorporated into the Honeywell product range.


MULTICS was a groundbreaking operating system that paved the way for modern computing. It introduced the concept of timesharing and symmetric multiprocessing, revolutionizing the way computers were used and managed. Today, MULTICS is a part of computing history, but its impact can still be seen in the technologies we use today.

Frequently Asked Questions

1. Was MULTICS the first operating system?

No, MULTICS was not the first operating system. However, it was the first timesharing operating system.

2. What is symmetric multiprocessing?

Symmetric multiprocessing is a type of multiprocessing where all processors share a common memory and are capable of performing the same tasks simultaneously.

3. Is MULTICS still in use today?

No, MULTICS is no longer in use today. It has been replaced by more modern operating systems.
