Chapter 1.9, Problem 1.1PP
Practice Problem 1.1 (solution page 28)
Suppose you work as a truck driver, and you have been hired to carry a load of potatoes from Boise, Idaho, to Minneapolis, Minnesota, a total distance of 2,500 kilometers. You estimate you can average 100 km/hr driving within the speed limits, requiring a total of 25 hours for the trip.
- A. You hear on the news that Montana has just abolished its speed limit, which constitutes 1,500 km of, the trip. Your truck can travel at 150 km/hr. What will be your speedup for the trip?
- B. You can buy a new turbocharger for your truck at www.fasttrucks.com. They stock a variety of models, but the faster you want to go, the more it will cost. How fast must you travel through Montana to get an overall speedup for your trip 1.67×?

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,

Print the ticket ID number, ticket description, ticket priority, ticket status, and, if the information is available, employee first name assigned to it for our records. Include all tickets regardless of whether they have been assigned to an employee or not. Sort it alphabetically by ticket status, and then numerically by ticket ID, with the lower ticket IDs on top.arrow_forwardFigure 1 shows an ASM chart representing the operation of a controller. Stateassignments for each state are indicated in square brackets for [Q1, Q0].Using the ASM design technique:(a) Produce a State Transition Table from the ASM Chart in Figure 1.(b) Extract minimised Boolean expressions from your state transition tablefor Q1, Q0, DISPATCH and REJECT.

The alarm does nothing while it is disarmed (‘switched off’). It canbe armed (‘switched on’) by entering a PIN on the keypad. Whenever thealarm is armed, it can be disarmed by entering the PIN on the keypad.If motion is detected while the alarm is armed, the siren should sound AND asingle SMS message sent to the police to notify them. 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
