MICROWAVE ENGINEERING

Ques 1. What is Microwave Engineering?
Ans. Microwave engineering is the study and design of microwave circuits , components , and systems. Fundamental principles are applied to analysis , design and measurement techniques in this field.The short wavelengths involved distinguish this discipline from electronic engineering . This is because there are different interactions with circuits, transmissions and propagation characteristics at microwave freque ....etc

The Intel 8051 microcontroller is one of the most popular general purpose microcontrollers in use today. The success of the Intel 8051 spawned a number of clones which are collectively referred to as the MCS-51 family of microcontrollers, which includes chips from vendors such as Atmel, Philips, Infineon, and Texas Instruments.

The Intel 8051 is an 8-bit microcontroller which means that most available operations are limited to 8 bits. There are 3 basic sizes of the 8051: Short, Standard, and Extended. The Short and Standard chips are often a ....etc

PIC microcontroller
PIC is a family of modified Harvard architecture microcontrollers made by Microchip Technology, derived from the PIC1650 originally developed by General Instrument's Microelectronics Division. The name PIC initially referred to Peripheral Interface Controller.The first parts of the family were available in 1976; by 2013 the company had shipped more than twelve billion individual parts, used in a wide variety of embedded systems.
Early models of PIC had read-only memory (ROM) or field-programmable EPROM for program storage, ....etc

1. 8051 was developed with what technology?
The original MCS-51 family of Intel was developed using NMOS technology, but later versions, identified by a letter C in its name (for example, 80C51) used CMOS technology and consumed less power than their NMOS predecessors. This made them more suitable for devices with batteries.
2. Why is it called 8051 8-bit micro-controller?
The Intel 8051 is an 8-bit micro-controller, meaning that most of the available operations are limited to 8 bits.
3. What is the width of the data bus?
8-bit data bus
