Ring, ring, ring.
But seriously...When I started in IT, you considered yourself lucky if you had your own, monochrome (green characters) terminal to access the mainframe. SOP was half a dozen people shared 1 terminal. Of course, the unlucky 5 people were busy desk coding before they created their punched cards and submitted a batch job, then watched (yes, watched) their report print out. No, I didn't walk 15 miles, uphill, both ways, to school.
Then came color terminals, on everyone's desk. Woo hoo! 1,920 characters, in color. Oh, the magic.
Then came the client server revolution, PCs on every desk. Servers. LANs. Radio buttons, drop down boxes, etc. all in the name of making us more efficient. Ooooh, weren't we lucky to have all that computing power on our desktops.
These days, due to all the security and privacy regulations, not to mention the costs of supporting 15,000 PCs, what are we implementing? Why, we are back to 'dumb terminals' accessing virtual desktops, running on servers (over 200 virtual desktops/server), in the data center to ensure data (PHI or PII) doesn't leak.
All someone needs to do is call the dumb terminals 3270s, call the servers 3274s and we're back to the future. If you don't know what the aforementioned numbers mean, ask someone in IT with gray hair, if you can find them. They'll be busy supporting COBOL or assembler programs with a copy of IBM/370 Principles Of Operations in their lap.
