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
Answer: star topology.
Explanation:
The layout of the way how the computers in a netword are interconnected is called network tipology.
Some types of network topologies are:
1) Point-to-point tipology: all the computers are connected to each other directly (computer-to-computer, in pairs, this is a direct link between each two computers).
2) Bus topology: all the nodes (computers or server) are connectect to a maing cable.
3) Star topology: all the computers are connected to a central computer or server which is called central hub. This is the layout described in the question.
4) Ring topology: the computers are connectec in a circular path; each computer is connected to the next computer.
5) Mesh: every computer is connected to every other computer.

Answer:
in what language?
python
```
while (1):
x = eval(input("What is your age?"))
if x>=20:
print("You can vote")
else :
print("You can't vote")
```
Explanation:
you get the user input for his age then you do an if statement to check if it is less or greater than 20 and print yes id it is =20 or bigger than 20 else you print no
