Describe the functions of ALU, resisters, CU, BIU, Cache and FPU.
Answer:
ALU :An arithmetic logic unit (ALU) is a digital circuit used to perform calculations and logic operations
Registers:register holds the address of memory where CPU wants to read or write data.
CU:The control unit (CU) is a component of a computer's central processing unit (CPU) that directs the operation of the processor.
BIU:BIU takes care of all data and addresses transfers on the buses for the EU like sending addresses, fetching instructions from the memory, reading data from the ports and the memory as well as writing data to the ports and the memory.
Cache:Cache is used to temporarily hold instructions and data that the CPU is likely to reuse.
FPU:A floating-point unit (FPU, colloquially a math coprocessor) is a part of a computer system specially designed to carry out operations on floating-point numbers.

2.2-2 Consider sorting numbers stored in array by first finding the smallest element n A of and exchanging it with the element in . Then find the second smallest A AOE1 element of A, and exchange it with . Continue in this manner for the firs AOE2 1 elements of A. Write pseudocode for this algorithm, which is known as selection sort. What loop invariant does this algorithm maintain? Why does it need to run for only the firs elements, rather than for all elements? Give the best-case n 1 n and worst-case running times of selection sort in ‚-notation.
Answer:
Follows are the explanation of the choices:
Explanation:
Following are the Pseudocode for selection sort:
for j = 0 to k-1 do:
SS = i
For l = i + 1 to k-1 do:
If X(l) < X(SS)
SS= l
End-If
End-For
T = X(j)
X(j) = X(SS)
X(SS) = T
End-For
Following are the description of Loop invariants:
The subarray A[1..j−1] includes the lowest of the j−1 components, ordered into a non-decreasing order, only at beginning of the iteration of its outer for loop.
A[min] is the least amount in subarray A[j.. l−1] only at beginning of the each loop-inner iterations.
Following are the explanation for third question:
Throughout the final step, two elements were left to evaluate their algorithm. Its smaller in A[k-1] would be placed as well as the larger in A[k]. One last is the large and medium component of its sequence because most and the last two components an outer loop invariant has been filtered by the previous version. When we do this n times, its end is a repetitive, one element-sorting phase.
Following is the description of choosing best-case and worst-case in run- time:
The body the if has never been activated whenever the best case time is the list is resolved. This number of transactions are especially in comparison also as a procedure, that will be (n-1)(((n+2)/2)+4).
A structure iterator at every point in the worst case that array is reversed, that doubles its sequence of iterations in the inner loop, that is:(n−1)(n+6) Since both of them take timeΘ(n2).

Write a program that reads the subtotal and the gratuity rate, then computes the gratuity and total.For example, if the user enters 10 for subtotal and 15% for gratuity rate,the program displays $1.5 as gratuity and $11.5 as total.Sample RunEnter the subtotal and a gratuity rate: 10 15The gratuity is $1.5 and total is $11.5Class Name: Exercise02_05
Answer:
Using Javascript,
function calTotal( subtotal, gratuity){
gratuityValue = subtotal * (gratuity/100)
total = subtotal + gratuityValue
console.log( "gratuity: ", gratuityValue , "\nTotal: ", total)
}
Explanation:
The javascript function above is able to collect two parameters subtotal and gratuity rate in percentage and calculate the total and gratuity value, and displays it on the console.
Where do today's computers store almost all motherboard configuration data?A) BIOS ROMB) CMOS RAMC) DIMM RAMD) Solid State Disk
Answer:
In the CMOS RAM
Explanation:
It's the only answer that is available. New computer's store the data in TPM (Trusted Platform Module) is an international standard for a secure cryptoprocessor, a dedicated microcontroller designed to secure hardware through integrated cryptographic keys.
Today's computers store almost all motherboard configuration data in CMOS RAM (Complementary Metal-Oxide-Semiconductor Random Access Memory). (Option B)
How is this so?CMOS RAM is a type of non-volatile memory that retains data even when the computer is powered off. It is typically powered by a small battery on the motherboard.
The configuration data stored in CMOS RAM includes settings such as system date and time, boot order, hardware settings, and other BIOS (Basic Input/Output System) configurations.
