D that’s the answer I learn that in my old school
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:
In reality, a diluted type of acetone that dissolves plastics and coating is Nail polish removers.
Explanation:
The chemical composition of the material has permanently changed, nothing else than if you had shot it. No repair but replacement is available.
Acetone does not get along with plastics.
This classic timelapse video shows just how cheap plastic acetone is.
When it's out, I have my new AirPods Pro. I got a odd smell when I opened the box when I received it. The little one is solid and chemical. It's new, I guess, and after days it will be gone.
But after ten days of use it doesn't. And the smell remains strong. It won't go quickly, I believe.
Instead I noticed that the smell is often shaping the silicone tips.
About 8 hours a day I use this AirPods Pro. Is it possible for a long time to use this smelling tip?
Actually, I must say they are soft and work well for noise cancelation, I love this silicone tip. If the strange smell doesn't hurt. To me, that's good.
Answer:
a. Telnet transmissions are not encrypted.
Explanation:
Indeed, since <em>Telnet transmissions are not encrypted,</em> all the information sent, and even the characters typed in the telnet console are sent in clear text.
This is a security issue, since any other device in the same network will receive a copy of the information (packets) sent. For default, all the devices, except for the server expecting to receive the information, will discard the packets. However it is easy to actively <em>listen </em>and keep those packets, wich will contain the information in plain text and human readable.
