How to understand SPOOLing?

by OS_peter / March 16, 2014 2:17 PM PDT

Hello Bro(s),

I was confused by the SPOOLing recent days. I found that the origin of SPOOLing was attached to the IBM 1401. According to the introduction, i think the SPOOLing's appearance because of no hard disk or other devices which can connect to mainframe at that moments. am i right or not?

well, we have so many device which can support fast input/output function now, why could SPOOLing remain and even more prosperous?

My first spooler was a long long time ago

It was way back when (look up a GE 210) and it dates to even before that. But in answer to your question, printers are still too slow to ask users to wait for the printer to complete before typing more in say Word.

Why not check your textbook

Why not check your textbook and/or ask the person leading the class you are clearly taking? As Bob said... While connection methods have gotten faster the printers really haven't. Next time you print something on a consumer grade inkjet printer, pay attention to how long it takes from the point of pulling in the paper to the time it feeds the completed sheet into the tray. Now imagine not being able to do anything with your computer that entire time. I remember back in the pre-Mac OS 8 days when there was no background printing, so combined with slow dot matrix printers, sometimes people would start a print job in the morning and then their computer would be tied up all day because they had to print off some quarterly results.

Teletypes and chain printers we had back then.

The OP seems to want to duplicate what can be found on the web. That's OK, let's see if anyone will write Google.

They made print buffers...

boxes you'd slip between the Centronics plug and jack. Buy a big enough one and you have your PC back fairly quickly.
