Service Based Company Vs Product Based Company

After all deep thinking, I came up with an idea of writing how the environments would be in service based companies and product based companies.

[SBC]Service Based Company :
The software engineer who works in a service based company has a big threat for Recession. This is because when once everyone in the world are computerized, there will be no one to give this company a project which implies there will be no software company that gives work to the Engineers employed.
A software engineer in a service based company feels frustrated just because he does the job allocated and there is no way to show his ideas/talent. If the project head says to implement his work in particular algorithm, there is no way of refusal to show his better idea(Still some company accepts the programmers idea, only some).

What is OOPs?

In this semester I am studying OOPs with C++.  I have already studied OOPs with C++ in my 12th standard. I wish to share whatever I understood about "What is OOPs?"

First of all, many thinks OOPs means C++. Not at all. OOPs is a concept which can also be implemented in C++. Object Oriented Programming is abbreviated as OOP. Objects are the successors of structures.

Why go for classes from structure?

Interesting concept that I understood - C++ & C

In functions, we would've heard about Call by reference concept which uses pointers. A simple program to explain "Call by Reference" would be as follows :

WWW

WWW which is expanded as World Wide Web is generally a part of any website's URL. You can see any website's URL starting with www. It is just a sub-domain but which all DNS record should contain for sure. Let's take three of my blogs for explanation.

1. http://www.krishnainfotron.com/
2. http://howtoblog.krishnainfotron.com/
3. http://www.tncif.krishnainfotron.com/

Redirect Subdomains

While explaining about URL, I told that http://forum.krishnainfotron.com/ and http://search.krishnainfotron.com/ as Redirect Sub-domains.

What is a redirect?
When a URL redirects to another URL, its called a redirect.

Wild Card Redirect

Wow! Blogger Follows Wild Card Redirect.

Lets take How to blog?

Its blogspot domain URL is http://www.krishnainfotron.blogspot.com/

Its Custom domain URL is http://howtoblog.krishnainfotron.com/

I was previously using this blogspot domain on a free domain : http://www.krishnainfotron.x10.mx/

I switched from http://www.krishnainfotron.x10.mx/ to http://howtoblog.krishnainfotron.com/

When I shifted from http://www.krishnainfotron.blogspot.com/ to http://www.krishnainfotron.x10.mx/ there was no fear that traffic will get lessened. 

When URL changes, how traffic won't get lessened?

Lets take two links from How to blog?,

Buying a domain.

When I said that I bought a domain, many asked bought a domain? From whom?

I wish to share a short story of mine here, http://scribbles.krishnainfotron.com/2012/04/experinece-with-buying-custom-domain.html

 

I bought a domain from a registrar.

Why should I pay for a domain?

CC TLD – What is it?

CC TLD – Country Code Top Level Domain.

Blogger has adopted CC TLD aliases. What is it? A very basic explanation can be done with a blogspot domain URL. Let’s take,

http://www.krishnainfotron.blogspot.com/

When this blog is viewed in India, the blog’s URL will be http://www.krishnainfotron.blogspot.in/

Difference between Custom and blogspot domain URL.

When you are using a blogspot domain URL, your blog is actually a sub domain of the TLD, http://www.blogspot.com/

Whereas, when you use a custom domain, either your own domain is used or sub-domain of your own domain is used to point your blog.

For example, blogspot domain URL of this blog is http://explanations-krishnainfotron.blogspot.com/ while, Custom domain URL of this blog is http://explanations.krishnainfotron.com/

URL?

Evolution of a name based URL is a big story. Yet, What is a URL?

URL – Universal Resource Locater.

Let’s start from our home, If someone needs to meet us/post us, they need an address that leads them/their post to us. Here people search you so they need your address.

In the same way, When you provide a Resource via Internet, It needs some address to be provided so that people can access your resource easily. That address may be called URL aka Web address.

This article may be considered a resource and it is provided at the address, http://explanations.krishnainfotron.com/.

Internet Protocols(IP) & Domain Name Servers(DNS)

Initially in the internet world, each one's computer was used as web server and files were hosted on it.

How to view the hosted site from a remote computer?
