What distinguishes a mainframe from personal computers? I tried to find the answer via web surfing, and found three things were often cited:
Mainframes are usually IBM's that run an IBM operating system or UNIX, and they offer: 1) Maximum reliable single-thread performance; 2) Maximum I/O Connectivity; and 3) Maximum I/O Bandwidth.
I haven't the slightest idea what this means (other than the IBM stuff.) Could someone translate into english, giving practical examples?
