The stage that precedes the implementation stage of SDLC is <u>testing</u> and it involves checking the functionality of the system.
System design involves the process of determining an overall system architecture, which typically comprises the following:
- Physical processing components.
Generally, there are seven (7) main stages in the systems development life cycle (SDLC) model and these include:
1. Planning.
2. Analysis.
3. Design.
4. Development.
5. Testing.
6. Implementation.
7. Maintenance.
From the above, we can deduce that the stage which precedes the implementation stage of SDLC is testing.
During the testing stage of SDLC, a quality assurance (QA) expert checks the system to determine whether or not it is functioning properly before it is deployed for operation, which is where the system can be used.

D. Absolute is the answer
Answer:
The maximum Data transfer rate is 320 Mb/s
Explanation:
The minimum microprocessor bus cycle duration = 100 input clock cycles and Data bus clock = 4.0 GHz = 4 × 10⁹ Hz
The maximum bus cycle rate = Data bus clock/minimum microprocessor bus cycle duration
Therefore, The maximum bus cycle rate = 4.0 GHz/100 = 4 × 10⁹ / 100 = 4 × 10⁷ = 40 × 10⁶ = 40 M/s
8 bits is equal to 1 byte, therefore 64 bit is equal to (64/8 = 8) byte.
Data transferred per bus cycle = 64-bit = 8 bytes.
The maximum Data transfer rate per second = bus cycle rate × data transferred per bus cycle = 40 M/s × 8 bytes = 320 Mbytes/s = 320 Mb/s.
The maximum Data transfer is 320 Mb/s
Answer:
b. 1/8"
Explanation:
In This scenario this installation does not require any penetration protection as long as the space between the electrical box and the wall membrane does not exceed 1/8 of an inch. This is mainly a safety precaution to prevent accident's such as an electrical fire or electrocution as well as meeting the specs for the rest of the house to be built perfectly without modifications.
New Interface, features like start screen, faster boot time, dynamic desktop, improved search function, windows love syncing, windows to go, and improved security.
