The differences are given below:

80286

1. Low data bus width (16 bit)

2. Returning from protected mode to

real mode is hard and complicated.

3. Small RAM/Memory

80386

1. High data bus width (32 bit)

2. Easy for 80386 3. Big RAM / Memory (Real memory = 4GB and virtual memory= 64TB)

What is the difference between a use-case diagram and class diagram?

Class diagram is UML structure diagram which shows structure of the designed system at the level of classes and interfaces, shows their features, constraints and relationships - associations, generalizations, dependencies, etc.Communication diagram (called collaboration diagram in now obsolete UML 1.x) is an interaction diagram which shows interactions between objects and/or parts (represented as UML lifelines) using sequenced messages in a free-form arrangement.So, the major difference is that class diagram shows static structure of the system while communication (collaboration) diagram shows system behavior as sequenced exchange of messages between objects.


What is the difference between activity diagram and sequence diagram?

Activity diagram shows the work flow from start point to the end point detailing many decision points. Sequence shows detail flow of specific use case and it also shows interaction between actors, system and system components


What is the difference between vector and phaser diagram?

A(t) = Am sin(ωt ± Φ) representing the sinusoid in the time-domain form. But when presented mathematically in this way it is sometimes difficult to visualise this angular or phase difference between two or more sinusoidal waveforms so sinusoids can also be represented graphically in the spacial or phasor-domain form by aPhasor Diagram, and this is achieved by using the rotating vector method.Ansh

What is the need for timing diagram in microprocessor?

The need for a timing diagram for a microprocessor is, primarily, to allow you to properly design the interface logic that will support the microprocessor. You need to know what lines are used to execute various data transfers, what are the timing of those lines with respect to each other, and how the microprocessor expects the external logic to behave. You can also use the timing diagram to understand how the microprocessor functions and, particularly, to know how long each instruction will take.

Difference between dataflow diagram and sequence diagram?

The purpose of a data flow diagram is to show you how the data flows through an information system. A sequence diagram shows you information regarding how the processes work together and in what order they operate.
