An abacus shows most of the relevant features of a computer for arithmetic processing. The operator moves sliders according to well defined rules, finally arriving at a correct answer without needing any depth of arithmetic knowledge.
no That is for early computers
this man is one of the persons who helped to develop early computers.
No computers weren't invented
The Pascaline is one of the early computers, it was invented by Blaise Pascal on 1642. It was named after him. by nazir
Computers were invented in the early to mid 1940s.
first generation computers were not fast and were less reliable.
Early Computers were large in size while today computers are compacted .Early Computers were Vaccum tube and transistor based while today computers are ICs based.Early Computers were slow and today computers are fast.Early Computers were used punch card for storage while today computers used Secondry storage ( Hard Disk) for storage.Early Computers were not user friendly todays computers are user friendly

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.
Military computers linked together so if one was hit, the others would still have the data.
There weren't any computers back then unless your talking about the one that was found in the sea near some really small island that dated back to the 1300's i think maybe A LOT earlier
No, microchips made missile guidance computers possible in the early 1960s. The microprocessor (a specific type of microchip containing a complete CPU) made microcomputers possible in the early 1970s and when microprocessors became powerful enough in the early 1980s, the first personal computers.
