View of Academic structure during the pre and post eras of Covid-19 virus attack

The famous global health pandemic has set a harsh impact on the mentality of every individual. On the sad truth of the prevailing situation it is sure that we cannot return to the world as it was before. There is a full stack of problematic situations which the world is facing at the moment such as most businesses spanning from small petty shops to multi billion cooperate companies is running a huge loss, prevalence of political imbalance in most countries, scarcity of water and food and barriers on education etc. The barriers in the Academics of the world an inevitable  hence, as a solution the emergence of e-education has compromised the world of education.

Before we move onto the current education system let’s go back to our traditional system of education and the pros and cons of such a system. We all had a physical classroom, a lively professor and tangible study material. Every day we attend classes not only for lectures but with lots of hopes and excitement. We go to meet our friends and loved ones. During the classes we had a chance of discussing the subject topics with our colleagues. We took part in many co curricular activities like sports, dancing and other society works. Our minds were scattered into many sectors instead we were not concerned and pressurized on books alone.

It is also a clear fact that studies should not be limited upon the boundaries of books and lecture slides everyday should give us an experience and we learn from it that would bring more efficient benefit. As we all go to school we meet a lot people with versatile set of abilities and strength, we accrued the chance to learn from them and teach another share the knowledge ultimately grow together as one community. On the other hand side we do faced some hard situations in this education system like the amount of time we spent on travelling and money spent on for daily chores. All humans aren’t the same there is a group of introverts also they don’t find comfort in being together sharing themselves with rest of the crowd. During the pre pandemic education system we spend a lot time away from our families especially, the students who stay from their home in boarding houses and hostels might have gone through home sickness.

Changes do occur that’s globalization. The hit of global pandemics has reversed all chores in world where as I already mentioned it has turned education up into a different angle. The gradual deuteriation of world education is not something easy to accept as a result, during the lockdown several actions were taken up by most countries to keep up the education ongoing. That’s how we landed up on the “Study from home” concept. Emergence of Zoom, Microsoft teams, cisco WebEx, gipsy and many other online meeting websites have given hands for the world of education. Students attend classes from home no need of daily travelling, saved a lot of pocket money and most importunately there was no any interruption during the lockdown in continuing their education.

In our traditional system of education we learn from our lecturers but once the routine turned up to education many student have adopted themselves to self study patterns. Self study is an important ability which the students should develop within them instead of spoon feeding education therefore, I would always be supportive towards the fact that this would be an efficient advantage towards the students. The studies of middle school and primary kids can be monitored by their parents and parents will have time to assist them. Even though the current system caters a great solution there is shortcoming in which everyone aren’t facilized. The continuation of online universities and colleges aren’t very productive. Lower middle class families in most Asian countries have financial instabilities they might find hard in top up their mobile data to carry out education online and then people from under coverage areas also do find hard in attending classes. It is also true many of us do not follow a good routine where we wake up late, skip the breakfast and attend the classes for the sake of it but in a traditional school that was opposite. Education courses like Medical Degree, civil engineering degree do require practical application in real world. Online tutoring those domains of degrees aren’t practical and efficient. Some universities are holding examination through online and providing grades they are using technologies like Lockdown browser and other alternatives but in my point of view I would recommend that it biased to hold the exams in such a system. The procedure of grading and ranking of the students based on online academic performance is not certain where as there is a high degree of risk in plagiarism and fraud.

Therefore, as per contrast in both the pre and post eras of pandemics and their impacts on education system do have their influence. In order to overcome this un avoidable situation the application of such a e-education would be the utmost solution but the continuation of such a situation will be not have a good impact on students. Traditional education system was always a good platform to learn new things and grow but when it comes to online education the symbiotic relationship in between the community is less hence, there would be a very little growth of education in the community.

REACT JS INTRODUCTION

What is REACT JS ?

In simple it is a framework of java Script(JS) as per the knowledge we have on past semesters , there should not be any alerting ideas that it might be used for validations as it sprung in my brain . Here , a frame work of JS can be used up for building user Interfaces . Where the React is highly focused on one thing which that one thing is really well that is involvement of React in building rich user interfaces . And on the other hand the React is not involved in routing or there is no HTTP request or response task involved in react . Hence , it is purely used up in the front-end development of a web application . 

This is a famous website known the Drop box which is written using React . Also FACEBOOK. React has been created and maintained by Facebook . 

Why is react so important ?

Since the origin of a language is also more important likewise , since it has been written using React . It has a huge community which lays behind . This aspect of react enhances the capability of it where you can find solutions in stack over flow and many other . It is a skill on demand . 

Important feature of React ?

This feature helps to break down the component into smaller compartments and then solve the problem . The cluster of this compartments build up the more complex User Interface . 

Re-usability of the code - The Article components which are used up in React can be simply be used in Angular and Vue. This is a very importantly used in enterprise level application . 

React is declarative if you ask a react a job to be done it will do it . its like as a developer you will only have to provide some instruction . In such a way it is easy for you to create tough websites . React will also handle efficiency in updating and rendering of components . with the mean time the Application changes the React will handle efficiency on handling updating and altering of components . DOM updates are handled gracefully at React .

Node JS in a Nut shell

What is Node JS ?

Its an open free server side language which runs of various platforms such as :- Windows , Linux , Unix , Mac OS and etc . 

Why do we recommend Node JS ?

The main unique feature of Node JS is it uses asynchronous programming . Which caters with a better server side efficiency compared to PHP / ASP.net . The main task any server side language is to open a directory from the server and retrieve data to according to the client requirement . Due to the single Threaded , non - blocking and  asynchronous nature of it high lightens its strength among the rest of the server side languages . 

Validate other server languages (PHP / ASP.net) vs. Node JS , in regard to the performance order ?

PHP Event handling order of performance 

1. Task assigned to the file system of the server . 

2. Client waits until the server opens the file and reads it . 

3. return the retrieved the content to the requested client . 

4.Ready to handle the next task . 

Here, It is clear that there is only one way communication we call it a synchronous communication . During a process been completed the other request cannot be made . when u look on the other hand Node JS eliminates the call blocking and simply moves into the next task . Lets go through the steps of Event handling of the Node JS. 

Node JS Event handling 

1. Task - A assigned by the client to the file system . 

2. Ready to handle Task - B .

3. While the server open and Read the file system for Task-B , mean while the server returns contents to Task-A . 

This is the advantage of the Node JS . Node JS has a capacity to perform such functions due to the single Threaded nature of which it possess . 

Modules of Node.js 

These modules are concepts which are equivalent to the JavaScript libraries . Simply they are set of functions which can be used without further installations .

To initialize a module we use the keyword require() while you assign it to a variable . as mentioned below :

var http = require('http');

after this you can access the module and connect the server as below :

http.createServer(function (request, response) {  response.writeHead(200, {'Content-Type': 'text/html'});  response.end('Hello World This is Ishma19'); }).listen(8080);

you can also create your own modules .

Node.js NPM

It is a packet manger for Node.js packages . There is a lot of managers but it is automatically installed once to install Node.js package. 

var uc = require('lower-case');

You use a package as same as how you initialize a module .

key Facts to know about JavaScript , No SQL and GIT

:JavaScript , No SQL and GIT can be the three useful concepts for a full stack development of a dynamic web application . Let’s go through three of those concepts in detail . 

JAVA SCRIPT

JavaScript(JS) is a Dynamic programming language which can be used up in the web based application development along with HTML and CSS .  JS concepts also involve in calculation , manipulation and Validation of Data sets in a web content. 

The fundamental unit of JS is an object . They form objects and interacts in an object-oriented level . Therefore we can conclude that JS it self serve as a dynamic object oriented language . JS basically comprises of three main categories as : class, object and prototype . The properties of JS and keyword classes are assigned in the constructor() method of JS. This method is called in order to create a new method . 

JS variables are initialized in two different ways they are : As copies and references . The assigning of primitive values can be initialized as copies and when the variables do not hold a primitive value instead in exist a reference to an object will initialized as references . 

JS scope is a tricky function . Most programming languages have scope. JS has 2 forms of scope : they are functional scope and global scope . functions have their own scope but blocks do not . 

JS closures are a means through which an inner function can refer to the variables present in its outer enclosing function after its parent functions have already terminated. 

NO SQL

SQL is where most of us are clear with which is the standard language to manipulate relational database .which is being effectively used up in the CRUD functions . SQL does spread its applications in the functionalities beyond CRUD functions in maintenance and manipulations of relational set of database . But on the other hand NO SQL is non-SQL which is free of relational schema and free of joints . These are mainly used up for companies in which use Tera bytes of data daily like Facebook, Twitter and so on . 

GIT

GIT is a version controlling tool . which allows you to keep record of any changes which take place over time any files then you can use the previous as prior versions . GIT will increase the quality of your software and facilitate collaboration and make a person a better developer .

Introduction to Application Framework

The application Framework is a predefined blue print . It provides the fundamental basic structure for the building up of any applications for a specific environment . These frameworks ease the work of developers for many reasons on contrast to the general development . The predefined code makes the system would be able to cater the developer with many advantages such as : reduction of errors , lower cost of development , reusable , save time , ease at work and many . The Application frame work not only be used to create the GUI but they are also used up in full stack development . 

The Application Frameworks are used up  based on Software Design Principles such as : Single Responsibility , open/closed , Liskov substitution , Interface segregation and Dependency inversion .They can be commonly known as SOLID principles which are widely accepted used by well experienced software engineers . 

when we go through the principles the problem could be easily figured out .Then the we have to consider about the  methodology of approaching the solution , here we use the general tack ticks we use in our day to day life . where firstly we have to think through the problematic scenario and ask questions from our client regarding the solutions to the problems . Split the problem into smaller fragments and get a solution which is termed as Divide and conquer . 

Implementing the solution can use different ways like YAGNI and TDD(Test Driven Development) etc.
