Answer: Detailed
Explanation:
SDLC consist of 7 phases. They are:
1. Planning.
2. System analysis and requirement
3. Design:
4. Coding:
5. Testing:
6. Installation
7. Maintenance
Here we are talking of the third phase. In this phase it is the design phase which consist of high and low level design. Here the preliminary design is included in high level design where it describes the required hardware, software, network capabilities and the modelling of the interface. However the detailed design in low level design will implement the coding and will finding of any errors in the implemented design as described by the preliminary design.
Answer:a) Mainframes, miniframes, PCs, desktop Internet computing, mobile computing
Explanation: The hierarchy of the computers or computing are in the generation is:-
- Mainframe:-designed for the execution of huge data processing , storage and execution.
- Miniframe:-has similar functioning as the mainframe but on smaller scale and version.
- Personal computer(PC):-It is designed for the individual purpose and according the need of the user.
- Mobile computing:-computing that can be done on the mobile phone similar to the computing on the personal computer
- Internet computing:-the computing of the mobile and computer system with the facility of the internet connectivity.
Answer:
Image processing operations implemented with filtering include smoothing, sharpening, and edge enhancement.
Answer:
I think that is
c. An increase in purchases of goods and services
Answer: Backtracking
Explanation:
Backtracking algorithm approaches a solution in a recursive fashion whereby it tries to build answers and modify them in time intervals as we progress through the solution. One such backtracking algorithm is the N Queen problem whereby we place N Queen in a chessboard of size NxN such that no two queens attack each other. So we place a queen and backtrack if there is a possibility that the queen is under attack from other queen. This process continues with time and thereby it tends to extend a partial solution towards the completion.
