Chapter 23, Problem 15RE
Explanation of Solution
Connecting to a POP server:
- POP server stands for Post Office Protocol.
- It is an application-layer Internet standard protocol which is used by email clients in order to retrieve email from a mail server.
- It defines the way user agents operate and how messages from and to mail transfer agents are formatted.
- POP is eventually going to be replaced by a new standard called Internet Mail Access Protocol.
- One can use the command “openssl s_client -connect pop.gmail.com:995”.
- Here, 995 denotes the port number enable access it via SSL encryption.
The following shows the results of connection made to POP server.
~$ openssl s_client -connect pop.gmail.com:995

What are the major threats of using the internet? How do you use it? How do children use it? How canwe secure it? Provide four references with your answer. Two of the refernces can be from an article and the other two from websites.
Assume that a string of name & surname is saved in S. The alphabetical characters in S can be in
lowercase and/or uppercase letters. Name and surname are assumed to be separated by a space
character and the string ends with a full stop "." character.
Write an assembly language program that will copy the name to NAME in lowercase and the surname
to SNAME in uppercase letters. Assume that name and/or surname cannot exceed 20 characters.
The program should be general and work with every possible string with name & surname. However,
you can consider the data segment definition given below in your program.
.DATA
S DB 'Mahmoud Obaid."
NAME DB 20 DUP(?)
SNAME DB 20 DUP(?)
Hint: Uppercase characters are ordered between 'A' (41H) and 'Z' (5AH) and lowercase characters
are ordered between 'a' (61H) and 'z' (7AH) in the in the ASCII Code table. For lowercase letters,
bit 5 (d5) of the ASCII code is 1 where for uppercase letters it is 0. For example,
Letter

Further motion shouldnot result in more messages being sent. If the siren is sounding, it can only bedisarmed by entering the PIN on the keypad. Once the alarm is disarmed, asingle SMS should be sent to the police to notify them.Two (active-high) input signals are provided to the controller:MOTION: Asserted while motion is detected inside the home.PIN: Asserted for a single clock cycle whenever the PIN has beencorrectly entered on the keypad.The controller must provide two (active-high) outputs:SIREN: The siren sounds while this output is asserted.POLICE: One SMS…arrow_forward
