Where did the operating systems come from?

If you buy a PC / laptop, the operating system is already on it or you can do it with a stick.

The first PCs did not have an operating system and since they were the first PCs, it was not possible to develop one.

How did they do it? Maybe there was magic in game 8O

The first mainframe computer that was ever built was developed by a person who designed aircraft carrier calculations for war planes, the first program codes actually only consisted of binary codes, i.e. 0 and 1, and of course the systems at least had the first for the user, namely the ddos.

Do you mean a problem, analogous to the "chicken and egg problem".

The first computers were little more than pocket calculators, back then they were still programmed with punch cards,

in the 1970s the Alair 8800 was programmed by literally typing in every bit individually.

Every computer had an operating system. It just depends on how "simple" it is. As far as I have read a long time ago, computers were "fed" with punched cards a dozen years ago (similar to these music boxes). So the operating system was that if you put a card with tiny holes in it in different places, the computer knew what that meant and what to do.

Later the operating system was built into an EPROM memory chip or similar on the main board of the computer. Although changeable when you opened the computer and also updateable in a complicated way with an EPROM burner, only that was done very rarely.

Microsoft put an end to this for the first time and delivered its operating system on floppy disks. Disadvantage: booting took a lot longer. Advantage: Updates much easier and no problems with licenses for operating system components, so cheaper.

Until today it has remained with the boot media and despite the extremely fast hard disks and computers that booting still takes a relatively long time. For comparison: a Commodore 64 with a CPU of only approx. 1 Mhz had loaded the operating system in less than 3 seconds, so that letters could already be entered. You can't even do that with 2000 Mhz and a super fast SSD.

Yes, but the recognition of the punched cards also requires an operating system. This was permanently installed on the computer board and was difficult to update or change.

As far as I've read it was Konrad Zuse… But I don't know whether that has anything to do with aircraft carriers and war planes. He supposedly built this in his private living room and the first version was destroyed in the war or something. I don't think that it was already in the war. That was just experimental. Only the second version after the war could really be used industrially.

Badly explained, no that was just hardwired.

The punched cards were the software (like e.g. DVDs today) … The operating system itself was not on punched cards. The FS asked about the operating system.

and i mean, the operating system used to be changeable… By soldering out chips or transistors or whatever was used and inserting new ones.

ma

If the operating system were also on punched cards without a higher-level operating system, then you would actually have this chicken-and-egg problem… But it's not like that. The operating system wasn't as software-like as it is today. It was hardware. Basically, it's still hardware today. The BIOS is actually the operating system. What we call the operating system, e.g. Windows 10 is only "reloaded" by the BIOS.

IBM introduced the OS / 360 operating system in 1964. It was the first operating system to be used extensively.

A Commodore 64 with a CPU of only approx. 1 Mhz clock loaded the operating system in less than 3 seconds, so that letters could already be entered. You can't even do that with 2000 Mhz and a super fast SSD.

If the operating system were programmed so "narrowly" today, as with the C64, today's computer would probably boot as quickly… Only the performance makes it possible to become more extensive… Burn a current operating system on a chip for a C64 and boot the (yes of course that won't work, but theoretically). Let's see how long it would take to process all of this… ^^

Even the good old C64 had an operating system. Without this you would have had to program everything in machine language so that something readable appears on the screen.

Incidentally, the C128 already had an operating system from Microsoft.

It was all about a pocket calculator, because he no longer felt like calculating everything by hand, you can read everything. Besides, I only spoke of war planes, not war. You can always build them.
