1. The computer depends on the operation speed 、 Storage capacity 、 Functional strength 、 Supporting equipment and other factors can be divided into (C).
A) Desktop computer 、 Portable computer 、 Laptop computer
B) Electronic tube computer 、 Transistor computer 、 Integrated circuit computer
C) Supercomputers 、 The mainframe 、 medium-size computer 、 Minicomputers and Microcomputers
D)8 It's a plane 、16 It's a plane 、32 It's a plane 、64 It's a plane
analysis According to the different electronic components used by the computer , Can be divided into ： Electronic tube computer 、 Transistor computers and integrated circuit computers .
Microcomputers are divided by word length , Can be divided into ：8 It's a plane 、16 It's a plane 、32 It's a plane 、64 It's a plane ,
Microcomputers are divided by size , It can also be divided into ： Desktop computer 、 Portable computer 、 Laptop computer
According to the operation speed 、 Storage capacity 、 Functional strength 、 Supporting equipment is divided into ： Supercomputers 、 The mainframe 、 medium-size computer 、 Minicomputers and Microcomputers .
2. Binary 3 Bits can represent (C).
