"Procrastination is the thief of time"

Famous adage said by Edward Young and I quote ‘Procrastination is the thief of time ‘indeed brim a glockenspiel for everyone. It is loud and clear that time is an indispensable facet of life as it roars “Switch in time saves nine”. Time is such an exigent thing, once it out the window, is lost till doomsday. Only a sensible person knows worth of time. When any person is capable of wrap up his/her work on time but he/she intentionally impediment his/her work and takes more time, that’s we call procrastination.

Procrastination is a multifarious behavior that affects everyone to some degree. If we are punctual and perform activities on time, then surely society will give us mammoth respect in return because ability to remain undeviating with our solid gold that requires massive will power, discipline and substantial determination is of paramount importance. The more we will procrastinate, more we will lose and ultimately things will turn to calamity because once time is lost, it can’t be retrieved. Stressing on this crucial issue, Holmes said and I quote “Pick my left pocket of its silver dime. But spare die right, for it holds my golden time”. That’s mean, Holmes was at beck and call to renounce his sliver, but not his time because time is having more worth than acquiring the sliver.

Student who wastes his/her ample time in wrong activities always suffer a lot .The students are unable to get good grades in their examinations in case of procrastination. There is a huge sense of carrying through for those people who are regular in their work especially in organization . The life offers us many chances and we need to grasp these opportunities before it’s too late. If the nature of work is touring, then person should design and manage his plan well in advance. He needs to prioritise his work because in this way he can get ample time by mow down extra distance and time. If person is not managing his travel plans according to time, ultimately that results cataclysm. So it is very important to understand dynamics of time during trips or travelling

 Procrastination is indeed thief of time because it steals away the delicacy of what lastingness of time from us. Time is tough nut to crack as far as humans are concern. Sluggish events in our lives always cost us because of gigantic detrimental outcomes. There are so many ways to overcome procrastination but first we have to understand the causes that could be of laziness, distraction or pathetic attitude.Time is the best medicine that heals all wounds. We have to do our work on time because time waits for none. Those people who ruin their time by doing nothing or waste in wrong doings, There is one famous maxim that suits best on them that “killing time is not a murder; it is a suicide”. So it is loud and clear that procrastination is harming a person itself and only wise make use of it fruitfully. Some people always look askance that they have no time to do anything .That is totally apocryphal because only wise person plans his activities according to his time .Time is powerful because it conquers all and we have no choice but to obey it .Each day is precious and each second is unique that deserves living to the maximum.


Waterfall Process Model

The Waterfall Model is one of the most important types of plan driven software engineering approach. The Waterfall Model is one of debilitated model that includes following steps 


Steps of Waterfall Model 

Requirement Gathering
In this step, we design our plan and according to that plan, we specify our requirements. What are our goals and what are our constraints. This is not an easy step. It requires a lot of attention and devotion. After having complete  analysis, we specify our requirements
Software/System Design
This step deals with an identification of system design based on initial requirement gathering. This phase is very important. The software/system design should completely reflect the requirements of the system. 
Coding & Unit Testing
 In this step, programmer writes a code based on proposed design. Each module of the system will be tested individually. For example, Admission and attendance system are two different modules of the student portal. The progammers write code of each module and each module will be tested individually. 
System Testing
 All modules are integrated and then tested to make sure that system is working as per defined standards 
Deployment
 The system is deployed in the practical  environment and then tested to make sure that it is working as per requirements or not. 

Condition when to use Waterfall Model
  1.   when requirements are understood
  2.   When our requirements are fixed and unambiguous

Alternatives of waterfall
The alternatives of waterfall include rapid prototyping that furnish user participation in early stages or to cater those functionalities of system that emerges. In rapid prototyping, all the specifications are being taken and we delicately go through that specifications. Moreover, in prototyping, we can redefine the requirements with changing requirements. 
 Pros of waterfall model
  • Waterfall model is very simple model
  • Stages are well-defined 
  • Documentation of waterfall is available  

 Cons of waterfall model
  •  Waterfall model does not cater changing requirements
  •  Percentage of  precarious errors is very much high
  •  Waterfall model is not suitable for sophisticated software.
  • Costly

Ubiquitous Web

 Ubiquitous means something that seems to be present everywhere and often rendezvous. In early 19th century, Mark Weiser introduced a word ubiquitous that refers the world where people are beleaguer by such kind of brilliant devices that are highly supportive. Perfect examples of these devices are mobile phones and tabs. Ubiquitous web bestow people ingess wherever and whenever they want to get with such a magnificent applications that are really flabbergasted and user-friendly 

 Applications mobility is one of the most significant behavior of ubiquitous that bring comfort for a user. The user can switch again to get access to the same application. In Ubiquitous applications, user can identify resources. Moreover, user can draw a plan that decipher in managing these resources within context or time frame for that sessions and then we implement the plan to achieve desired results.

    Features of Ubiquitous Web
    The key features of Ubiquitous web are as under.
  1. Ubiquitous web is dynamical
  2. User preferences and reconcile environmental conditions
  3.  Ubiquitous web responds to the events exactly from the servers over the network
  4.   Ubiquitous web enables multiple applications  in devices   
  5.  Ubiquitous web manages resources mainly in term of temporary session

Semantic Web

The Semantic web is the kind of web that elucidates the information in such a splendid way that the computer can easily pick and understand. The Semantic web is basically an  appurtenance of current web that includes information required for well apt communication mechanism between the computer and people. There is a myth that semantic web is all about consists of links between different web pages, which is totally apocryphal. The Semantic Web not only includes the links between different web pages,but it also deals with an amplification between things and premises of things.

Meta data  is all about data about data  One of the best advantage of the semantic web is that it arranges the content of web pages in a systematic way. The Semantic web  is not a set asunder web but it is an annex of current web. To make Semantic web count or to make it functional able, all properly structured collections must in reach to the Computers.

Tools for Semantic Web 

There are two important readable machines/ tools for Semantic Web
XML
    
 XML stands for extensible Marking Language. It is similar as HTML in which we add tags that are  invisible to the people, but are visible to the computer.

RDF

RDF is an abbreviation of resource description framework. It is a language that elucidates information and as well as resources on web. The RDF contains subject, object and property. The Subjects and objects are identified by universal resource identifier (URI)

Why Students Fail in College

In college life, students mostly come across with the prevalent statements from teachers and parents like you can’t indulge in extracurricular activities; first finished off the college work. The fear is usually infusing in college student’s mind that if he/she will not study diligently, then he/she can’t accomplish the goals for the rest of life. Still, many students flounder and fail. It’s a crystal clear fact that education is of paramount importance in flourishing the future of any country, so it’s a well apt idea to ponder over the roots of student’s failure at college.

Root Causes of Student Failure at College
The major root causes of the student failure at college are as under

Lethargic Educational System

The lethargic education system is one of the core reasons that college students fail in their examination. The present educational system implicates mammoth students in the tantamount classroom with different abilities, science of mind, and interests.The college curriculum is turning millions of students into robots. If the doctor prescribed the exact same medicines to all the patients, then result would be tragic. When it comes to college, this is exactly what happens. When one teacher stands in front of 30 students, and each student is having different needs, strengths, abilities, and dreams. If teacher teaches the same thing in exactly the same manner which is horrific. The college curriculum is designed by the policy makers, and most of which have never taught a day in their life. The other indolent aspect of education system is that it favors memorization over the research.These docile aspects demotivate the students and many of them are unable to succeed at college.

Poor Study Habits 

Many students fail at college because of their imbecilic study habits as they don’t give their dedicated time to their study.The students  don’t explore endless learning opportunities like college library books, neither they have reading habit, therefore, many students can’t survive in college.

Procrastination of time 
The famous adage said by Edward Young and I quote ‘Procrastination is the thief of time ‘is indeed, brim a glockenspiel for everyone. It’s a loud and clear that time is an indispensable facet of life as it roars “Switch in time saves nine” phenomena  Procrastination is a multifarious behavior that affects studies of the college student. The more college student will procrastinate, more he/she will lose and ultimately things will turn to calamity because once time is lost, it can’t be retrieved .Stressing on this crucial issue, Holmes preferred golden time over sliver dime as he was at beck and call to renounce his sliver, but not his time because time is having more worth than acquiring the sliver.

Poor understanding of Question Paper

The understanding of the questions is a part of an examination. Sometimes, exam questions are precarious that requires brainstorming. If student reads a question wrongly, then how come he can answer in aptly manner? This is one of the core reason, student fails in college examinations. So understanding the questions are of paramount importance. The examiner usually gets annoyed over poorly articulated answers by the student which further affect the student’s performance
