allright. good for you.

actually last paper hence no intrest :3

can u explain relative adressing :3

Relative Addressing is telling how much forward or backward to go from the current position of code segment. Eg: If the instruction is JMP +10 it means in relative addressing to increase the current location by 10 to get the desired target location.

 

[hope4thebest]

In the trace tables for example of addressing do we have to write one value in each line of the table.

not exactly

 

[hope4thebest]

not exactly

ok it means it is not neccesary to write each data value in each line?

 

[AlphaBeta]

whats database schema

u can do in a trace table format..

 

[:: A^]

whats database schema

it is the structure of the database.

it is the structure of the database.

bro how many advantages of using relational data base over flat files did u learn

 

[:: A^]

Data duplication is avoided
program independance
security
Better validation
easier to produce queries.

Thatd be 5 i guess.

a simple five would have suffice yeah i have learned the extra point of limited access and data integrity

ah something made me think that if i would have posted just five, you would have asked me what those five were
