Windows Application Architecture(WAA) is also known as 2-Tier Architecture.

It is the combination of Windows Application plus Network Programming.

It comes in 1992 and is called Client Server Technology. Server tier contains database whether it is RDBMS or DBMS and the client tier contains executable forms(.exe). Client tier access database which is stored at the server side and display on the client side. So, the disadvantage are

  • Both the tier must have same operating system.
  • Every client have executable forms that excess database from server tier
  • Dedicated LAN protocol are used
  • 2-Tier application can be extend to 3-Tier application

3-Tier Application :-

These type of architecture used in Internet application or Intranet application.

This type of architecture can be extended up-to n-Tier.

Client tier is also known as thin tier browser and the client tier only have the browser.

This architecture allow us to connect different type of devices having any type of operating system such as Desktop PC can access the database.

  • There is no need to having same operating system for networking.
  • Mobile browser is also known as Light browser.
  • GPRS: General Purpose Radio Services.

One thing is common all the devices having at least browser. So, there is no need to put .exe files on the client side like 2-Tier.

It supports different type of protocols with different types of system. So, there is no need to having only LAN type protocol like 2-Tier. It may be HTTP or any other protocol like IEEE 802.11

Middle tier and database tier both are server tier & client may have different machine, operating system and protocol

The thing extra here is webserver. It is an extranet that actually receives the request from client and pass to middle tier and response come back to the client machine again. It treats as firewall.

These language need to web browser to run, they are not stand alone application so they run by using any other application.

Scripting language can be classified into two types:-

  1. Client side scripting:- Client side scripting means it will be execute client side machine itself. The example of client side is HTML(HTML is used to display the content in web browser where as XML used to store data ).
  2. Server side scripting:- Server side scripting means it will be execute on server then it will send response back to the client machine.

Naming convention of Identifier:-

  1. It always begins with any alphabet or underscore.
  2. It is any combination of alphabet, digit & underscore.
  3. Variable length is depend on the compiler.
  4. No special symbol & no space are allowed except underscore.

The programmer can’t inter-fear in these words in the same way as you, in, an.

Keyword always written in the small letter.

There are 34 keywords in C which are as follows:-

  1. void
  2. char
  3. int
  4. short
  5. long

  28. break
  29. continue
  30. goto
  31. return
  32. near
  33. far
  34. huge

From 1 to 9 are used as a string data type(primary data type)

From 10 to 12 are used for loop control structure

From 13 to 14 are used for selection control statement

From 15 to 17 are used for case control structure

From 18 to 21 are used for storage class

From 22 to 24 are user defined data type

From 25 to 32 are miscellaneous

From 33 to 34 are pointers (additional keyword)
