Chapter 6, Problem 4DQ
Explanation of Solution
Difference between estimating activity durations and estimating the effort required to perform an activity:
- Duration is the time taken to complete an activity or task in a project. Activity duration is affected by the individual resources involved in it.
- The duration and effort are different to each other.
- Effort is the resource estimate and the hard work required to complete an activity. Estimated activity duration relates to time estimate...

2. [20 pts] Student A B will enjoy his picnic on sunny days that have no ants. He
will also enjoy his picnic any day he sees a hummingbird, as well as on days where
there are ants and ladybugs.
a. Write a Boolean equation for his enjoyment (E) in terms of sun (S), ants
(A), hummingbirds (H), and ladybugs (L).
b. Implement in Logisim, the logic circuit of E function. Use the Circuit Analysis tool in
Logisim to view the expression, include an image of the expression generated by Logisim
How would I go about creating this computer database in MariaDB with sql?
Create a database name "dbXXXXXX" Select the database using the "use [database name]" command.
Now you are in the database.
Based on the above schema from Enrolment System database, create all the tables with the last 6 digits of "123456", then the table name for table Lecturer should be "123456_Lecturer". Refer to basic SQL lecture note to create table that has primary keys and Foreign Keys. Provide the datatype of each attributes.
Add a column called "Department" with datatype "VARCHAR(12)" to the table "Lecturer". Shows the metadata of the updated "Lecturer" table. (Use Describe command)
Drop the "Department" column from the table "Lecturer", and show the metadata of the updated "Lecturer" table.
Insert three (3) data to each of the table in the tables created.
Note: If you have foreign key issues, please disable foreign key constraints before inserting the data, see below
SET FOREIGN_KEY_CHECKS=0;…

Based on these, answer the following: (a) (b) (c) (d) What are the maximum/largest numbers that can be stored in the system by these three forms defined above? (express your answer in decimal values) What are the non-negative minimum/smallest numbers that can be stored in the system by the denormalized form? (express your answer in decimal values) How many numbers (both non-negative and negative) can be represented in the above mentioned system using the general form? Explain your answer.

- R languagearrow_forwardUsing R languagearrow_forwardCompare the security services provided by a digital signature (DS) with those of a message authentication code (MAC). Assume that Oscar can observe all messages sent between Rina and Naseem. Oscar has no knowledge of any keys but the public one, in the case of DS. State whether DS and MAC protect against each attack and, if they do, how. The value auth(x) is computed with a DS or a MAC algorithm. In each scenario, assume the message M = x#####auth(x). (Message integrity) Rina has the textual data x = “Transfer $1000 to Mark” to send to Naseem. To ensure the integrity of the data, Rina generates auth(x), forms a message M, and then sends M in cleartext to Naseem. Oscar intercepts the message and replaces “Mark” with “Oscar.” Will Naseem detect this in the case of either DS or MAC? If yes, how will Naseem detect it? If not, why? (Replay) Rina has the textual data x = “Transfer $1000 to Mark” to send to Naseem. To ensure the integrity of the data, Rina generates auth(x), forms a message…arrow_forward
