Answer:
requirement analysis
Explanation:
The goal of the requirement analysis phase is to specify the system inputs, processes, outputs, and interactions in greater depth. The system's operations would be specified at the functional level by the end of this phase, which means that the functions and features to be done will be defined but not necessarily how they will be executed. Requirements Analysis should not evaluate computer software, documents, or data streams unless expressly restricted by the Project Charter. The risks associated with how the system will be integrated into the standard operating procedures will be identified and considered during the requirements analysis. The functional and system requirements of the business process, as well as the user and operational needs, will be collected throughout the requirements analysis.
The phase where developers identify the particular features and functions of a new system is the requirement and analysis stage.
What is system development?System development is the process of defining, designing, testing, and implementing a new software application or program.

Convert (765)octal into hexadecimal
Answer:
1F5
Explanation:
First convert octal 765 into binary values with each octal digit as a representation using 3 bits
Octal 7 ==> 111
Octal 6 ==> 110
Octal 5 ==> 101
Putting it together we get
111110101
Now group the bit values into groups of 4 (with leading zeros if necessary) starting with the rightmost bit.
Groups are highlighted and then the hex value is written
Right-most group 111110101 and 0101 is 5 hex
Middle group: 111110101 and 1111 is F hex
Left most group: 111110101 ; with leading zeros it is 0001 which is 1 hex
So from left to right we get 1F5
