Answer:
Run directory services
Explanation:
LDAP (Lightweight Directory Access Protocol) is an open protocol used to access some information, information that is stored in a network, the information is organized hierarchical structure, we could find some data like names, directories, and telephone numbers.
With other options, we can find DHCP to assign IP addresses and to resolve IP addresses to host names, we have the DNS.
Answer:
The answer is "All of these could make good functions
".
Explanation:
In the given question some information is missing, that is options which can be described as follows:
a. Ask the user to confirm an input with a yes/no answer
b. Sort some input data into an ordered list
c. All of these could make good functions
d. Calculate a complex mathematical expression
A method is a collection of ordered code and provides a generic code, that is used to execute a single, connected operation.
- A good function is a function, which takes values from the user and it will sort all the data and store in memory, and whenever we call the function, it will give the values.
- It is also used to calculate some complex values,
Answer:
B
Explanation:
This feels like an error on the question issuer's part.
Answer and Explanation:
Given that total number of records in a file = 100000
Each record consists of= 240 bytes
Given that B= 2400 bytes.
Then total blocks in file = 100000 records * 240 / 2400
= 10000 blocks.
Time that will take for exhaustive read
= s + r + b.btt
= 16 + 8.3 + (10000) * 0.8
= 8024.3 msec
Now as per given X be the number of records that are searched randomly and it takes more than exhaustive read time.
Hence, X (s + r + btt) > 8024.3
X (16+8.3+0.8) > 8024.3
X > 8024.3/25.1
So that, X > 319.69
Hence, atleast 320 random reads should be made to search the file
