Keeping secure username and password do not guarranty to provide complete security to your computer system. However, secure username and password offer the first line of defense against unauthorized access to computers. Because no matter how secure a username and password is, it can be stolen and ha-cked.
With the advancement in ha-cking techniques, secure username and password can be easily stolen. However, keeping a secure username and having a strong password gives you some edge of protection but it does not provide you complete protection from unauthorized access.

The bakery has requested the following custom variables:
-customer’s first name
-customer’s last name
-a coupon percentage off
-the date that they became a newsletter subscriber
Create an appropriate variable for each of these four items.
Then create string for the custom newsletter text that will show up before, between, and after each custom variable.
For example, “Hello,” might be the first string, followed by the variable carrying the customer’s name, followed by “Thanks for subscribing to our newsletter!” Your custom newsletter text should greet the person, then offer them a coupon, and then thank them for being a loyal customer.
Add placeholder names and information to populate into the variables for testing purposes by making up data for each. You can use your own name, for example, as this is simply a prototype or proof of concept. To do this, remember that the equals sign = between a variable and its value assigns that value to the variable.
Finally, use the print function to display the final newsletter text that includes all the required variables. This will display a final string that reads like a plaintext newsletter with the variables appropriately replaced by the defaults for each that you set in Step 1.
We can also combine two strings together in a single print function by using the + sign like this:
print(greetingTxt + firstName + bodyTxt1)
Code:
firstName = "Bill"
lastName = "Nye"
coupon = 15
joinDate = "January 14, 1973"
print("Hello, " + firstName + lastName)
print("Thanks for subscribing to our newsletter!")
print("Here's a coupon for " + str(coupon) + "% off for being subscribed since " + joinDate)
Output:
Hello, BillNye

Wants to test a program he suspects may contain malware. what technology can he use to isolate the program while it runs?
If he wants to test a program he suspects may contain malware, then the technology he can use to isolate the program while it runs is, B.Sandboxing.
Sandboxing can be described as a type of technology that uses the phenomenon of isolation to segregate a suspected file or program and then observes that distrustful program. If the program exhibits threatful activity under observation then it is removed so that the system can be protected by inhibiting its spread. Hence, the correct option is Sandboxing
On the other hand, Address Space Layout Randomization (ASLR) does not involve isolation as it just functions by arbitrarily organizing the address space locations to protect the memory contents. Hence, ALR Address Space Layout Randomization is not the correct option.
Process isolation usually is not involved in protection purposes as it just prevents the overlapping of different processes so that they do not intermix with each other. Hence, Process isolation is not the correct option.

The statement " you will be safe from downloading viruses as long as you have software to monitor your computer" is false.
Softwares such as firewalls and different types of anti-viruses play a role in protecting your computer from various viruses and potential hackers by monitoring, detecting, and eliminating the virus. Still, they alone cannot provide the protection as they need the support of the user. The user must show responsibility from his side and use the system wisely by not entering into threatful websites or downloading pirated files. The user must ensure before plugging any device that it is free from any kind of malware and may not be harmful to the computer. The user should use and maintain a secured connection.

Does implementing a trie using a dynamic child pointer array rather than a static child pointer array increase the big- time of lookups? why or why not?
Trie is an efficient knowledge return data format. Using Trie, search complexities can be brought to the optimal limitation (key length).
What is Trie? A trie is a sort of k-array search tree, a tree data structure used for locating particular keys from within a set. It is also known as a digital tree or prefix tree. These keys are typically strings containing isolated characters rather than the complete key defining linkages between nodes. Strings are kept in a unique data structure called a Trie that looks like a graph. There are nodes and edges in it. At most 26 children can be found in each node, and edges join each parent node to its offspring. An excellent matching technique, a trie (pronounced try) gets its name from retrieval thanks to its structure.To learn more about array, refer to:

Why can we have at most one primary or clustering index on a file, but several secondary indexes?
The reason is that there is only one physical way in which the actual data may be structured. A secondary index is a distinct data structure with references to the rest of the data that is arranged around its own keys.
Index structures are used in databases to create an index with identifiers and pointers to the blocks so we can access the block directly or limit the number of blocks that need to be searched, hence reducing the number of block accesses. The key values are the values in the column. The retrieval performance of the table will be enhanced by creating an index for each column that will serve as the foundation for table retrievals.

Describe each of the following types of memory and how they have advanced modern computing.
a. capacitor memory
b. cathode ray tube memory
c. ferrite core memory
d. semiconductor dynamic ram
The types of memory are capacitor memory, cathode ray tube memory, ferrite core memory, and semiconductor dynamic ram.
a. Capacitor memory:
Regenerative capacitor memory is a kind of computer memory that stores data bits using the electrical property of capacitance. These memories must be frequently refreshed (also known as regenerated) to prevent data loss because the stored charge gradually drains away.
b. Cathode ray tube memory:
When a dot drawn on a cathode ray tube (CRT) screen produces a positive charge encircled by a negatively charged region, storage happens. The information can be read by inducing a positive voltage pulse in a metal plate that is attached to the tube's face.
c. Ferrite core memory:
The transformer cores for core memory are toroids (rings) made of a hard magnetic substance, typically a semi-hard ferrite, with each wire passing through the core acting as a transformer winding.
Each core is traversed by two or more wires. Each of the cores has the ability to "remember" or store a state thanks to magnetic hysteresis.
d. Semiconductor dynamic ram:
