👉 A microcontroller is built around a processor. 👉 A processor accomplishes its tasks by executing instructions in a sequential fashion. This means that the processor’s operations are inherently constrained: the desired functionality must be adapted to the available instructions and, in most cases, it is not possible to accomplish multiple processing tasks simultaneously. 👉 The instruction set is designed to be highly versatile and nowadays instructions can be executed at extremely high frequencies; however, do not eliminate the disadvantages of a software-based approach to digital design. 👉 It would be extremely convenient if every new design could be built around a digital IC that implements the exact functionality required by the system: no need to write software, no instruction-set constraints, no processing delays, just a single IC that has input pins, output pins, and digital circuitry corresponding precisely to the necessary operations. we can approximate this methodology using FPGAs.

Why Use an FPGA When a Microcontroller Would Do?

What Is an FPGA?  FPGA stands for field-programmable gate array. At its core, an FPGA is an array of interconnected digital subcircuits that implement common functions while also offering very high levels of flexibility. 

It was a great show showcasing all the new trending technologies.. Main thing was IoT, which will be changing the future in coming years..

22) Can structures be passed to the functions by value? Passing structure by its value to a function is possible, but not a good programming practice. First of all, if we pass the structure by value and the function changes some of those values, then the value change is not reflected in caller function. Also, if the structure is big, then passing the structure by value means copying the whole structure to the function argument stack which can slow the program by a significant amount. 23) Why cannot arrays be passed by values to functions? In C, the array name itself represents the address of the first element. So, even if we pass the array name as argument, it will be passed as reference and not its address.

Based on response v received.. Numbers would be even more..

Now some more people attending tech Mahendra interviews.. Let us say all the best to them👍👍👍

#Congratulations Some 500+ people applied for capgemini 2months back!! Out of 500 members 23 have got call letter for written test. Out of 23.. 4 have got offer letter... Congratulations to one who selected.. We feel very much happy bcoz it helped people! Complete efforts by people who placed efforts.. We just referred as like your friend...

21) Difference between RISC and CISC processor. RISC (Reduced Instruction Set Computer) could carry out a few sets of simple instructions simultaneously. Fewer transistors are used to manufacture RISC, which makes RISC cheaper. RISC has uniform instruction set and those instructions are also fewer in number. Due to the less number of instructions as well as instructions being simple, the RISC computers are faster. RISC emphasise on software rather than hardware. RISC can execute instructions in one machine cycle. CISC (Complex Instruction Set Computer) is capable of executing multiple operations through a single instruction. CISC have rich and complex instruction set and more number of addressing modes. CISC emphasise on hardware rather that software, making it costlier than RISC. It has a small code size, high cycles per second and it is slower compared to RISC.

High In-Demand Programming Language Frameworks & Tools For Machine Learning Engineers

👉 Deep learning is one of the various approaches to machine learning. 👉 Deep learning was inspired by the structure and function of the brain, namely the interconnecting of many neurons. 👉 Artificial Neural Networks (ANNs) are algorithms that mimic the biological structure of the brain. 👉 In ANNs, there are “neurons” which have different layers and connections to other “neurons”. 👉 Each layer picks out a specific feature to learn, such as curves/edges in image recognition. 👉 It’s this layering that gives deep learning its name, depth is created by using multiple layers as opposed to a single layer.

Example: Suppose Humans might tag pictures that have a cat in them versus those that do not. Now, the algorithm tries to build a model that can accurately tag a picture as containing a cat or not as well as a human. When the accuracy level is high enough, the machine has now “learned” what a cat looks like.

MACHINE LEARNING 👉 Machine learning is a way of achieving AI. 👉 That basically means you can get AI without using machine learning, but this would require building millions of lines of codes with complex rules and decision-trees. 👉 So instead of hard-coding software routines with specific instructions to accomplish a particular task, machine learning is a way of “training” an algorithm so that it can learn how. 👉 To do this, we need to feed huge amounts of data to the algorithm allowing the algorithm to adjust itself and improve. 

“Blocks” on the blockchain are made up of digital pieces of information. Specifically, they have three parts: 1. Blocks store information about transactions, say the date, time, and dollar amount of your most recent purchase from Amazon. 2. Blocks store information about who is participating in transactions. A block for your splurge purchase from Amazon would record your name along with Amazon.com, Inc. Instead of using your actual name, your purchase is recorded without any identifying information using a unique “digital signature,” sort of like a username. 3. Blocks store information that distinguishes them from other blocks. Much like you and I have names to distinguish us from one another, each block stores a unique code called a “hash” that allows us to tell it apart from every other block. 

What is Blockchain, Really? If this technology is so complex, why call it “blockchain?” At its most basic level, blockchain is literally just a chain of blocks, but not in the traditional sense of those words. When we say the words “block” and “chain” in this context, we are actually talking about digital information (the “block”) stored in a public database (the “chain”).
