Computer Fundamentals

The computer is termed computation. For calculating or computing something the device that has been used is known as the computer. Or we can say that for performing a fast arithmetic operation the device that has been used is a computer. Storing, processing, and retrieving are the main features of a computer.

Help me with these computer architecture questions, please. I need help with questions 1 and 2.
On a typical microprocessor, a distinct I/O address is used to refer to the I/O data reg- isters and a distinct address for the control and status registers in an I/O controller for a given device. Such registers are referred to as ports. In the Intel 8088, two I/O in- struction formats are used. In one format, the 8-bit opcode specifies an I/O operation; this is followed by an 8-bit port address. Other I/O opcodes imply that the port ad- dress is in the 16-bit DX register. How many ports can the 8088 address in each I/O addressing mode? .
