Explain what a lookup table is (assembly). Write pseudo code
Answer: Lookup table
In computer science, a lookup table is an array that replaces runtime computation with a simpler array indexing operation. The savings in terms of processing time can be significant, since retrieving a value from memory is often faster than undergoing an "expensive" computation or input/output operation.[1] The tables may be precalculated and stored in static program storage, calculated (or "pre-fetched") as part of a program's initialization phase (memoization), or even stored in hardware in application-specific platforms. Lookup tables are also used extensively to validate input values by matching against a list of valid (or invalid) items in an array and, in some programming languages, may include pointer functions (or offsets to labels) to process the matching input. FPGAs also make extensive use of reconfigurable, hardware-implemented, lookup tables to provide programmable hardware functionality.
If Peyton Manning, a professional football player, wanted to remember his 16-digit credit card number, which of the following memory techniques would you recommend? Group of answer choices He should think of the numbers as a sequence of football statistics. He should picture each of the numbers in his head printed in a bright color. He should first memorize a few other sequences of 16 digits to gain some practice. He should visualize the front of his credit card showing a picture of him dribbling a basketball.
Answer:
He should think of the numbers as a sequence of football statistics.
Explanation:
One of the most common mnemonic devices that researchers suggest is that of trying to link the thing we want to memorize to something that is relevant to our own life. In this example, Manning would benefit from linking the numbers to something that he finds revelant, such as football statistics. This increases the probability of him remembering these numbers.

Restart the tabletRestart the projectorExplanation:
When such problems occur, the basic and quick troubleshooting step is to restart the device or devices involved.
Restart the tablet: This could come in handy regarding this problem. The inability to connect to the projector could be due to the inability of a specific service or driver needed for the projector. Restarting the tablet will load up the drivers and services again to enable smooth connections. When a restart is done, bugs are fixed, internet connection is rectified, memory leaks are stopped, performance is aided, the RAM (Random Access Memory) is flushed or cleaned. This should resolve the problem, however, if not, try number 2.Restart the projector: There are driver software on projectors, and due to one system failure or another, these software may fail to load. This could affect its connection to another device. As done in (1), restarting the projector will fix those bugs and load up, which should solve the connection issue.What is the system that consists of nonproprietary hardware and software based on publicly known standards that allow third parties to create add-on products to plug into or interoperate with the system?
Answer:
Open systems
Explanation:
Open systems are very different from Open Source applications or software, it should not be confused.
Open systems work with the blend of open software standards, portability, and interoperability. Computer systems that interoperate among multiple standards and vendors to ensure that computer resources (hardware and software) are not allotted to a particular vendor. Such computer systems are considered as open systems.
For instance, computer systems that run a Microsoft Windows OS can be considered as an Open system. This is because of their capability to run different versions of the Microsoft Windows OS on that particular computer system. More clearly, A computer with Windows 10 OS, can be used to install Windows 8 OS without any issue. That same computer system can run the Windows 7 OS. This makes the computer system and open system.
Sara is writing a program to input her monthly phone bills and output the month name and amount for the month with maximum amount. She has defined an array to hold the month names. Complete the pseudocode program. [6] # Program to output maximum month's phone bill MonthName ["January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December"] # Define an array to hold the phone bills for each month
Answer:
double [] phoneBills = new double[12];
Explanation:
Since the question has requested that an array be difined to hold phone bill for each month. Above declares an array that will hold floating point number (double) and it has been created to hold 12 values representing the months January to December
Values can be added in the array as shown in the program below.
public class PhoneBill {
public static void main(String[] args) {
String [] MonthName = {"January", "February", "March", "April", "May", "June", "July", "August",
"September", "October", "November", "December"};
double [] phoneBills = new double[12];
phoneBills[0] = 4.5;
phoneBills[1] = 4.5;
phoneBills[2] = 5.5;
phoneBills[3] = 6.5;
phoneBills[4] = 3.5;
phoneBills[5] = 5.5;
phoneBills[6] = 6.5;
phoneBills[7] = 7.5;
phoneBills[8] = 8.5;
phoneBills[9] = 4.5;
phoneBills[10] = 3.5;
phoneBills[11] = 7.5;
System.out.println("Months and corresponding phone bill");
System.out.println(Arrays.toString(MonthName));
System.out.println(Arrays.toString(phoneBills));
}
}
The output of this program is attached:
Final answer:
To complete Sara's pseudocode for identifying the month with the highest phone bill, an array to hold the phone bill amounts is defined and iterated through to find the maximum bill and its associated month.
Explanation:
Sara is trying to write a program to track her monthly phone bills and identify the month with the highest bill. To complete Sara's pseudocode, you would need to define an array to hold the phone bill amounts for each month, similar to how she has defined an array for MonthName.
The pseudocode might look something like this:
Define an array PhoneBills to hold the monthly phone bill amounts
Initialize a variable maxBill to hold the maximum bill amount
Initialize a variable maxMonth to hold the month of the maximum bill
Use a loop to iterate through the PhoneBills array
Inside the loop, compare each bill to maxBill and update maxBill and maxMonth if the current bill is higher
After the loop, output maxMonth and maxBill
Here is a more detailed version:
maxBill = 0
maxMonth = ""
For i = 0 to PhoneBills.length - 1
If PhoneBills[i] > maxBill Then
maxBill = PhoneBills[i]
maxMonth = MonthName[i]
End If
Next i
Output "The month with the highest bill is " + maxMonth + " with an amount of $" + maxBill
This pseudocode will identify the month with the highest phone bill and output the result.
