Answer:
The correct answer for the given question is option(b) i.e " No subject line"
Explanation:
In the e-mail subject is the important part which describe the information which kind of particular mail is send or received .if we do not give any subject line in the e-mail header then most of the chances that email will not read by recipients due to this suspicion will be caused.
Unknown Sender and Multiple recipients do not cause suspicion so the correct answer is option(b) i.e No subject line".
The result of sending the string above into a variable that has allocated space for 8 bytes is that there will be Buffer Overflow Attacks.
<h3>What occurs when a string of data sent to buffer is large?</h3>
A buffer overflow is also known as buffer overrun. This is known to be a process that occurs when or if the size of data is known to be more than the storage capacity of any kind of memory buffer.
Note that due to the overload, the program that is trying to write the data to the buffer will therefore overwrites to the adjacent memory locations.

Answer:
D. ARPANET was developed
Explanation:
ARPANET is an acronym for Advanced Research Projects Agency Network and it was established in 1969 by the Advanced Research Projects Agency (ARPA) of the United States Department of Defense.
ARPANET was the first wide area packet switching network for transmitting electronic data and communications between computers on a single network with a distribution functionality. The TCP/IP protocol was first implemented on the Advanced Research Projects Agency Network (ARPANET), as well as some other standard protocols such as the NCP and the 1822 protocol.
The development of ARPANET happened first in the evolution of the internet.
E-mail is an acronym for electronic mail and it was invented by Ray Tomlinson in 1971; World Wide Web was created by Tim Berners-Lee in 1990; Web 2.0 evolved in 1999.
Answer:
A 1 MB digital file needs 0.23 seconds to transfer over a channel with bandwidth 10 MHz and SNR 10 dB.
Explanation:
We can calculate the channel capacity using Shannon's Capacity formula:
C = B + log₂ (1 + SNR)
Where C = Channel Capacity
B = Bandwidth of the Channel
SNR = Signal to Noise Ratio
We are given SNR in dB so we need to convert it into a ratio.
= 10log₁₀ (SNR)
10 = 10log₁₀ (SNR)
1 = log₁₀ (SNR)
SNR = 10¹
SNR = 10
So, using Shannon Channel Capacity formula:
C = 10 x 10⁶ log₂ (1 + 10)
C = 34.5 MHz
Total amount of time required to transmit a 1MB file:
1MB = 1 x 8 Mbytes = 8Mb
C = 34.5 MHz = 34.5 Mb/s
Time required = 8Mb/34.5Mb/s = 0.23 seconds
A 1 MB digital file needs 0.23 seconds to transfer over a channel with bandwidth 10 MHz and SNR 10 dB.
Indeed, this is to be true as software is to programs and applications(apps) hardware is to physical computers such as hard drive, SSD, motherboard, ram, graphics card, ect...
