This
conversation is between two friends...
Bade : hey chote.. what doing ??
Chote :
Nothing yaar just watching Olympics and feeling sad about Saina… she should have won gold
Bade: don’t worry next Olympics she will make us proud
Chote: yeah she should?
Bade: What else??
Chote: Do you know there is some weird tower at the Olympics?
Bade: Arey pagal
it’s not weird tower it’s a radical advance in the architectural field…which
was not possible without computer systems and its architecture. :D
Chote: Oh! Is it !! That’s great
Bade: Yes man.
Chote: Can you please tell me about the architecture and its importance.
Bade: Sure man …First tell me what do you know about system architecture
Chote:
I heard there is something related to IRCTC and 3-tier, 2-tier AC...
Bade: OMG *He will kill me with his intelligence* …Arey chote I thought you are smart!!
Chote: Yup I am smart.
Bade: Yeah I can see that by the way you related IRCTC and architecture, don’t worry I will make you little better by explaining it.
Chote: Oh
Bade: There are different kinds of architecture as you said 1 Tier, 2 Tier, and 3 Tier
Chote: Tell me about 1 tier.
Bade: Here you go, It’s very simple look all the processing is done on only one machine & number of clients attached to this machine
Mainframe
systems is a perfect example
Chote: Now I will explain 2- tier …there will be 1 system on 2 tyres like our scooter
Bade:
No no no Please don’t use your brains, its more advanced version of 1 tier
Client & Database is on different system, Processing is done at client side and Application layer is at client side
.
Chote: Thanks for making me intelligent
Bade: Good that you’re able to understand. Now I will tell you about 3- Tier
Apart from Application & database layer there is one more layer present at client side.
(eg Browser).
First Tier= presentation Tier Second Tier=Application Tier (Business Logic)
Third Tier=Data Tier (Database Server)
Chote: So much knowledge in 10 mins great
.
Thanks Bade
Bade:Not a problem chote now you can stop worrying about that weird tower
