Operation time complexity for an ARRAY

The time complexity of handling the operations in a data structure like an ARRAY are as follows:

i. Almost all the operations are O(1) [i.e. omega times one]
ii. Remove/Insert operations that handles element between elements require O(n) [i.e. omega times n] because the elements need to be shifted.
Note! Hence, an array as a data structure is used where remove/insert operations are not required.
