Hello students, in this question we are looking at the different types of addressing modes and their advantages and disadvantages.
00:08
So, first case we have direct and extended addressing.
00:16
So, we have two cases direct and extended we are looking at some of its advantages and disadvantages.
00:25
So, first we have looking at the advantages.
00:28
So, it is effective addressing calculated sum of contacts and so we can write this is an absolute also known as absolute addressing.
00:39
It possess address of actual location in memory.
00:44
So, this have an actual location hence it is very simplest simplest addressing mode is direct.
01:00
Now, we are looking at the advantage of extended.
01:04
So, in the extended it allows the access to a larger memory access we have a larger memory access in the extended addressing mode and suitable for large data.
01:22
So, we have large memory space suitable for data.
01:41
So, these are the advantages of direct and extended.
01:44
Now, we are looking at the disadvantages.
01:48
So, it have a very limited space this is the main disadvantage of the direct addressing mode whereas, the disadvantage of the extended is it is very complex.
02:03
So, more complex than any other and it require additional instructions...
