No one could possibly know, unfortunately.
Answer:
<u>the first friend</u>
Explanation:
It is important to <em>remember </em>that a core is the brain of the CPU (central processing unit), which means one who has a dual-core is having <em>"a dual brain" </em><em>to process information faster.</em>
Consider also, IT experts often acknowledge that in terms of speed of execution, it is proven that, "dual-core systems" are <em>faster</em> (even twice faster) than a "single-core system". The other friends were wrong because they disagreed with a widely accepted fact that dual-core is faster than single-core; and of course, <em>we know that without them being faster they can't run twice the applications and twice the data. </em>
Therefore, we can make the conclusion that the first friend's response is correct.
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.
