As with all computers early mainframes did not multitask (early microcomputers did not multitask, early minicomputers did not multitask, early supercomputers did not multitask). Now almost all computers multitask. Multitasking has nothing to do with the size of a computer, it is almost entirely a software feature of the OS running on the computer.
These days? Very little; in the old days a 'mini' was something that fit into 1 room; a mainframe typically occupied several rooms and a PC (micro) was a desktop... Nowadays, my calculator is a micro if you want to use the truest sense of the word. Today's calculators are more powerful than the worlds first Mainframe computers.

Computers 50 years ago weren't really "computers" as we know them. Mostly anything that used a CPU appeared more mechanical/electrical than a stand alone desktop or personal computer. (Things that used a CPU were machines that didn't look anything like computers) Now just look at your smart phone, or go check out the ipad (apple.com) Computers now give us a better picture of what is, what should have been and what will be.

The five eras of Data processing starts with Mainframe computers, personal computers, client server, enterprise and cloud computing. Now the era goes in cloud computing.
The major vendors in the market right now are IBM (itself has 90% market share), Groupe Bull, Unisys, HP and Oracle (Sun Microsystems).

Inkwells are now obsolete since the ballpoint pen came into widespread use.

HTML training itself is not considered to be obsolete. However, there are some techniques and programs in past training that are now considered to be obsolete.
Because..a. floppy drives are no longer installed in computers and.. b. it would take over 500 floppies to equal just one memory stick with 1GB of memory on it. Now you know..
becasuse now everything is able to be recorded and documented to back up memories passed from generation to generation..the irony is we are now going backwards...using computers, and they are very fragile and limited in their use. Writing doesnt need electricity to be used or a special size this or that for it to be readable like computers do, when its our turn to be dug up like the Romans and Mayans are now, there will be no trace of us...just obsolete computers everywhere! - with no way to get access to the information! xD...I love it..
The computer I bought two years ago is already obsolete. That is an obsolete design and you can't find parts for it any more.
