Answer:
The first question should be "What is the purpose of WLAN ?" .
In order to design a stable and better WLAN user should understand the purpose or intended use of WLAN.
For example : A school's wireless network will be different than the corporate wireless network.
In order to design the WLAN in a better way . User should know following
1. What is the purpose of the WLAN ?
2. How many users will be using it at a time ?
3. How many users will use it over all given a period of time ?
4. What are the common applications being used ?
5. Who will be using the WLAN?
6. Is there any legacy devices that need backward compatibility ?
So unless user doesn't understand the complete purpose and requirement of the WLAN, it is not possible to give the best design for the same. Capacity and Coverage needs to be taken care while designing WLAN.
Explanation:
as explained above.
The correct answer: Data independence
Data independence<span> is the type of </span>data<span> transparency that matters for a centralised DBMS. It refers to the immunity of user applications to changes made in the definition and organization of </span>data<span>. Physical </span>data independence<span> deals with hiding the details of the storage structure from user applications.
</span>
The logical<span> structure of the data is known as the 'schema definition'. In general, if a user application operates on a subset of the </span>attributes<span> of a </span>relation<span>, it should not be affected later when new attributes are added to the same relation. Logical data independence indicates that the conceptual schema can be changed without affecting the existing schemas.
</span>
<span>The physical structure of the data is referred to as "physical data description". Physical data independence deals with hiding the details of the storage structure from user applications. The application should not be involved with these issues since, conceptually, there is no difference in the operations carried out against the data.</span>
