Types of Interrupts in the 8086 Microprocessor

The 8086 microprocessor utilizes various mechanisms to handle external events and internal errors. These mechanisms are categorized into three primary types of interrupts: Hardware, Software, and Internal (Exceptions).

1. Hardware Interrupts

Hardware interrupts are generated by external hardware devices to request service from the microprocessor. The 8086 supports two hardware interrupt pins:

• INTR (Interrupt Request)

  This is a maskable interrupt, meaning it can be enabled or disabled using the IF (Interrupt Flag) in the flag register. When an external device wants to interrupt the microprocessor, it sends a signal on the INTR pin.

  The 8086 acknowledges the interrupt if the IF flag is set, and the INTA

Microprocessor vs. Microcontroller

ii) Differentiate Between a Microprocessor and a Micro-Controller

Microprocessor

Definition:

A microprocessor is a central processing unit (CPU) on a single integrated circuit (IC) chip that performs the processing functions of a computer.

Functionality:

• It only includes the CPU core and lacks other components like memory, I/O ports, timers, and other peripherals.
• Requires external components like memory (RAM, ROM), input/output devices, timers, and other peripherals to function as a complete system.

Usage:

• Primarily used in systems requiring high computational power and flexibility, such as desktop computers, laptops, servers, and high-end embedded systems.
• Suited for applications where customization of peripherals

What is a Firm?

Let us now try to understand the meaning of a 'firm'. A firm is a focal point of the production system of any country. A firm produces goods with the help of its own resources. Sometimes these resources are borrowed from outside, and they are paid remuneration (price) for using them, for example, land, labor, capital, etc. A firm is an organizational unit, while a plant is a 'technical unit'. The objective of a firm in organizing such factors of production is to maximize profit. In other words, profit is the main objective of a firm. Any decision of a firm is taken in accordance with this objective.

Fundamental Auction Concepts

Payoff: A bidder's payoff is their valuation for the item minus the price paid.

Social Surplus: This is the sum of the surpluses of all participants. The formula is: Seller's Surplus (p) + Winner's Surplus (v - p) + Loser's Surplus (0). Here, v is the winner's valuation and p is the price paid. Social surplus is maximized, and the auction is considered efficient, if the winner is the bidder with the highest valuation.

Types of Auctions

English Auction

This is a type of ascending auction where an auctioneer announces prices, and bidders accept or reject them.

• Winner: The last remaining bidder.
• Price: The second-highest price or bid.
• Information Revealed: The auctioneer learns the valuations of all bidders except for the
