Answer:
1. Float
2. Integer
3. String
4. Boolean
5. Float
6. String
7. Integer
Explanation:
To identify data types, we need to understand the following concepts.
Data types are categorised into 2.
1. Numeric data types
2. Non numeric data types
The numeric data types are represented by numbers and is subdivided into 2.
i. Integer: Numbers without decimals (could be positive or negative)
ii. Float or Real: Numbers with decimals (could also be positive or negative)
Going by the above illustration,
13.5 and -20.4 are float data types
-6 and 12345 are integer
2. Non numeric data types: These are data that are different from numbers or digits. They could be images, string & character, boolean, dates, etc.
I'll limit my explanation to the scope of this assignment.
String are texts and are denoted by open and close quotes ("...") i.e. data that are present with quotes are strings
Boolean are data with true or false values
So, by this explanation:
"18 Mingle Lane" and "Bonjour" are strings variables
And
False is boolean

Answer:
According to the requirements of users of the system, RAID 10 is more suitable option.
Explanation:
As mentioned previous server is running RAID 5, Which takes a lot of time to manage parity while reading or writing data.
On the other end RAID 10 is the combination of RAID 1 and RAID 0, It has the the features of both system.
According to the users requirement, unscheduled downtime or data loss can cannot be tolerated. So RAID 10 has the ability to access the data from multiple disks. If one disk i down, required data can be gathered from other disks.
It creates multiple duplicates of data, so risk to lose data has also been reduced.
<em>In both aspects, RAID 10 is better than RAID 5, so he choose RAID 10 for up gradation.</em>
