Describe the evolution of microprocessors.

• Microprocessors have only been used in personal computers since the 1990s.

• The evolution of microprocessors began with the Intel 4004 in the 1970s, progressing through 8-bit, 16-bit, 32-bit, and 64-bit architectures, with significant advancements in performance and efficiency.

• The evolution of microprocessors has been linear with no major breakthroughs.

• The first microprocessor was developed in the 1980s by AMD.

What is the architecture of the 8086 microprocessor?

• The architecture of the 8086 microprocessor is a 16-bit architecture without any bus interface.

• The architecture of the 8086 microprocessor is a 32-bit flat architecture with no segmentation.

• The architecture of the 8086 microprocessor is an 8-bit architecture with a single processing unit.

• The architecture of the 8086 microprocessor is a 16-bit segmented architecture with a Bus Interface Unit and an Execution Unit.

Explain the programming methods used with the 8086.

• Database management systems

• The programming methods used with the 8086 include assembly language programming, high-level language programming, macro assembly, direct memory access, and interrupt handling.

• Object-oriented programming techniques

• Web development frameworks

What are the common program development tools for 8086?

• Graphics design software

• Text editors

• Assemblers, debuggers, emulators (e.g., MASM, TASM, DEBUG, DOSBox)

• Compilers

Define interrupts in the context of microprocessors.

• Interrupts are permanent changes in the microprocessor's operations.

• Interrupts are only used in high-level programming languages.

• Interrupts are signals that temporarily halt the microprocessor's operations to address urgent tasks.

• Interrupts are signals that enhance the microprocessor's speed.

What is an interrupt service procedure?

• A method for optimizing CPU performance.

• A procedure that manages memory allocation.

• An interrupt service procedure is a function that handles interrupts in a computer system.

• A function that executes system calls.

List the key signals generated by the 8086 microprocessor.

• MREQ (Memory Request)

• CLK (Clock Signal)

• ALE (Address Latch Enable), DEN (Data Enable), DT/R (Data Transmit/Receive), IO/M (Input/Output Memory), INTA (Interrupt Acknowledge), WR (Write), RD (Read), HOLD (Hold), HLDA (Hold Acknowledge), RESET

• IRQ (Interrupt Request)

What are the basic configurations of the 8086 system?

• CPU, Hard Drive, Monitor, Keyboard

• CPU, Memory, Input/Output Devices, System Bus

• Memory, Cache, Graphics Card, Power Supply

• Processor, Storage, Network Interface, Display

How are system connections established in an 8086 architecture?

• System connections in 8086 architecture are established via address and data buses, controlled by the CPU's control signals.

• System connections are established through wireless signals.

• Connections are made using only the data bus without control signals.

• The CPU does not play a role in establishing system connections.
