In events start-of-selection is default event. When we have to use this event explicitly? Why?
The default event in the ABAP is Start-of-selection.We have to call explicitely this event when you are writing other than ths event , that is when you write AT SELECTION-SCREEN EVENTS OR INITIALIZATION EVENT etc,you have to explicitely mention the Start-of-selection event while you are writing the logic.
Before these events called ,all the code you have written come into this default Start-of-selection screen event.

What is the differences between ABAP and OOABAP. In which situation we use OOABAP?
OOABAP is used to develop BSP/PCUI applications and also anthing involved object oriented like BADIs, SmartForms..etc.where as ABAP is used to develop traditional programs in R/3.

What is table buffer? Which type of tables used this buffer?
buffer is nothing but a memory area. table is buffered means that table information is available on application server. when you call data from database table it will come from application server.
transperent and pooled tables are buffered. cluster tables can not buffered.

What is the use of pretty printer ?
Exactly where can we link the functional module to abap coding.
Pretty Printer is used to format the ABAP Code we write in ABAP Editor ,like KEY WORDS in Capitals and remaining are in small letters which is also depend on system settings.
We can call the function module in the ABAP Code .Press the Pattern button on Appl. tool bar then u will get box where u write the function module NAME which u want to call in the code by selecting the radio button CALL FUNCTION. In this way we link function module to ABAP Code.
What is the difference between SAP memory and ABAP memory? Exactly where can we link the functional module to abap coding.

Answer1:
data sending between main sessions using get parameter and set parameter is sap memory
data sending between internal sessions using import or export parameters is abap memory
Answer2:
sap memory is a global memory whereas abap memory is local memory.
For example, we have four programs in abap memory and assigned some varibles to a particular program in abap memory then those varibles can't be used by anyother program in abap memory i.e., the variables are only for that program and also local to that memory,whereas sap memory can access all the abap memory or else it can perform any kind of modifications.
