Answer:

The following are the explanation for each command, with the SMTP protocol considering only RFC 821.

Explanation:

The key commands of the SMTP protocols which take the RFC 821 into account are as follows:

HELLO -  

A client receives that order to describe himself  

HELP-  

It asks by the receivers to submit the command information as argument  

QUIT -  

It is used to terminate the message.  

-FROM MAIL  

The clients use it to acknowledge the message's sender.  

NOOP -  

The client does not use any procedure to verify the receiver status as required by the receiver's reply form.  

RCPT-  

The user needs it to determine the intended beneficiary.  

SAML-  

It sends or ends the specific mail which is sent to the mailbox or the SAML

RESET-  

The existing email transaction is aborted.  

SEND- The mail to be sent by the recipient's terminal, not its mailbox, is specified.  

TURN-  

It allows the sender to change position and recipients.  

VRFY-  

Verification checks the recipient's address.

One friend claims that a dual-core system runs at twice the speed as a single-core system; another friend disagrees by saying th
lidiya [134]

Answer:

<u>the first friend</u>

Explanation:

It is important to <em>remember </em>that a core is the brain of the CPU (central processing unit), which means one who has a dual-core is having <em>"a dual brain" </em><em>to process information faster.</em>

Consider also, IT experts often acknowledge that in terms of speed of execution, it is proven that, "dual-core systems" are <em>faster</em> (even twice faster) than a "single-core system". The other friends were wrong because they disagreed with a widely accepted fact that dual-core is faster than single-core; and of course, <em>we know that without them being faster they can't run twice the applications and twice the data. </em>

Therefore, we can make the conclusion that the first friend's response is correct.

A personal identification number (PIN) that opens a certain lock consists of a sequence of 3 different digits from 0 through 9,
Elan Coil [88]

Answer:

<u>720</u> possible PIN can be generated.

Explanation:

To calculate different number of orders of digits to create password and PIN, we calculate permutation.

Permutation is a term that means the number of methods or ways in which different numbers, alphabets, characters and objects can arranged or organized. To calculate the permutation following formula will be used:

nPr = n!/(n-r)!

there P is permutation, n is number of digits that need to be organize, r is the size of subset (Number of digits a password contains)

So in question we need to calculate

P=?

where

n= 10   (0-9 means total 10 digits)

r= 3     (PIN Consist of three digits)

So by using formula

10P3 = 10!/(10-3)!

        =10!/7!

        = 10x9x8x7!/7!

        = 10x9x8

        = 720

If you use your computer primarily for telnet into a remote computer, will you have a large long distance telephone bill?
Nikolay [14]

If you use your computer primarily for telnet into a remote computer, a person will not have a large long distance telephone bill.

<h3>What is telnet used for?</h3>

Telnet is known to be a kind of a network protocol that is said to be used to virtually look into a computer and to give a two-way, working hand in hand and text-based communication channel that exist between two machines.

Note that, If you use your computer primarily for telnet into a remote computer, a person will not have a large long distance telephone bill because it does not apply in any way.
