Answer:
Systems analysis phase.
Explanation:
In a systems development life cycle (SDLC) model, the purpose of the systems analysis phase is to build a logical model of the new system.
In the systems analysis phase, the system developer examines or analyzes the information or data about the requirements of an end-user, which are then implemented to achieve the organizational set goals and objectives.
Hence, systems analysis refers to the process of gathering data or factual informations, understanding processes, problem identification and suggestions of probable solutions for an effective and efficient functioning of the system.
Answer:
-32 to +31
Explanation:
6 bit 2s complement representation will be of the form b1b2b3b4b5b6 where each bit is either 0 or 1.
The largest positive number that can be represented using this scheme is 011111
Translating this to decimal this is 1*2^4 + 1^2^3 + 1^2^2 + 1^2^1 + 1^2^0
=16 + 8 + 4 + 2 + 1 =31
The smallest negative number that can be represented using this scheme is 100000
Translating this to decimal = -1 * 2^5 = -32
So the range of decimal values that can be represented is -32 to +31.
