Computers have characteristics such as speed, accuracy, diligence, versatility, and storage capacity. Limitations include lack of intelligence, lack of emotions, and inability to think creatively.

The functional block diagram includes input devices, output devices, central processing unit (CPU) containing control unit and arithmetic logic unit (ALU), memory, and secondary storage.

Computer networks include LAN (Local Area Network), MAN (Metropolitan Area Network), and WAN (Wide Area Network). Network topologies include mesh, bus, star, ring, and hybrid configurations.
