What are Mainframes?

gumbaru.

Oh so that’s why when I went to H-mart and I checked out, there was a old-school system (but in color)

Should i get into mainframes as a career living in Canada?

i thought they were a box with a stupid amount of storage like 10 billon terebyts

It’s 2024 on my era, mainframes and cobol are still here

Bro can't be replaced By AI

A terminal emulation PROGRAM, Linus.

So disappointed.

Cut my teeth on an IBM 1620/1710 decimal based mainframe w/ mag core storage, card reader/punch, card printer, A/D I/O, and a 10Mb washing machine size removable HDD. Then migrated to IBM 360, IBM 370, IBM 3033 mainframes on TSO, CICS, JES 2, JES 3, etc., and all their OSs and programming languages.

big iron is the name i give to my #$%^

Fun fact: if you wear shades and type into a black background with green text really fast and say "i gotta hack the mainframe" with 2000s techno music playing you can break into the most secure mainframes.

As a mainframe programmer since 1969 and who wrote millions of line of assembly code, i can tell you that once you code for a mainframe, yoy will never go back to the PC world again.
I feel bad for programmer who never had the pleasure or programming or even touching a mainframe. Even though i am a recently retired CIO, and 13 programming languages under my belt, i miss my days on "big iron"

I had no idea mainframes were still in use. Wild.

Main frame is good for big banks that don't want lose many to hacking

it's more than 25 y that i work on mainframe system, and i never heard the phrase "big iron". Is it only english/american nerd slang ?

IBM forgot more about buliding computers than all other together have ever known and always have one bit more.😁

Fraud Linus

Yeah but do they have an OS? Can you play games on a mainframe? All you did was say a whole lot of nothing without specifying any of the more curious details half of the viewers came here for.

Don't make videos anymore. None of my questions were answered.

Thank you!

I usually refer to Mainframes colloquially as “Big Old Throbbers”

I suggest you do servers vs mainframes

This was not very helpful for those unfamiliar with the terminology

which computer handles Taylor Swift concert tickets?

😂 cut and paste this video on every school website.😂

I wonder if that terminal UI is the same one for the AS/400 from 1980? I know Terminix and Prime Pharmaceutical still use this UI as I was trained on both over the past two years.

I get a chuckle out of all of the silly comments made based on someone’s knowledge of a PC. A mainframe is nothing like a PC. Listen to what he’s telling you!

doing a google a search ["mainframe hardware computer manufacturers today -software"]... This is a market that only IBM owns... Once there were many others... Now it is only IBM..... What a niche to own!

I recently joined an insurance company which uses mainframe for its transaction processing for policy endorsements, this video was useful as i had no fucking idea what the heck mainframe was

I managed Dr Amdahl’s last mainframe development in the 1980s … in the process we also developed what we called Compiled Code simulation… we developed the processor using … wait for it … Pascal … we wrote a set of rules for variable names and all the constructs we needed … once we had all the functionality developed… we wrote a compiler to generate a gate and net list from the exact same pascal source and when we ran our tests the verification files were generated… these three files went to the chip manufacturer and we used Rev 1 chips …

I worked on (programmed and lead software design teams) for “Big Iron” mainframes (360/370, etc) for almost 40 years. When mini computers (which didn’t last) started to come on the scene, talk was that they would “replace MFs.” I had a DEC mini-computer person call me up to understand how we solved a very complicated statistical problem on a MF. I spent about 5 minutes describing the process we used (which involved creating millions of extracts to be sorted to inflate our small amount of sample date to project the results at 4 organizational levels of the universe of data answers). When I finished I asked him, “Can you do that on a mini computer?” All I heard was silence and then he thanked me before he hung up.

I saw a picture of a T-Rex chewing up some mashed metal and the caption said, “Mainframes are back and they are Mad!” I used to say that PC’s are fast but Mainframes SCREAM!

And look how far we’ve come with “Big Iron” MFs since then. Mainframes SCREAM!

Man thanks u are so smart

Melding of iron and clay

You are a great presenter!

Used to do work using a mainframe, back in the 80s, at a university. Then it was Macs and PCs. I had no idea that they were still in use until I saw this video.

effin nerd

I used to move them things around. Took an appliance dolly with straps. We had false floors with cable runs underneath.

Mainframes were never out of business and will never be in near future. At least for all of them who are reading this comment, will still see them around! ;)

So mainframes are basically just what we call as standalone servers?

Why do people insist on showing pictures of tape drive cabinets and calling them mainframes? The cabinets of the classic large mainframe like 3090 are beige and blue boringness.

Linus when I hear "big iron" I think a heavy caliber six shooter.

Buahahahah I'm invincible!!!!
