Answer: It is used to map MAC addresses to IP addresses.
Explanation: <3
Using An assembly code
Read a 3 digit number from one row, then a 1 digit number from the second row. Subtract the 1 digit number from the 3 digit number, and display the result. Make sure you print your name first, then your output.
Sample Input
123
1
Output
Name Last name
122
Sample Input
100
1
Output
Name Last name
099 (or you can display 99 without the 0, either one is fine)
Sample Input
001
1
Output
Name Last name
0 (or you can display 000, either one is fine by me)
An example implementation of the algorithm you described in x86 assembly language using NASM syntax:
The Assembly Language Programsection .data
; Define your data here if needed
section .text
global _start
_start:
; Print your name here
; Read the 3-digit number
mov eax, 3 ; number of characters to read
mov ebx, 0 ; file descriptor (stdin)
mov ecx, buf ; buffer to store the input
mov edx, eax ; maximum number of characters to read
int 0x80 ; invoke the read system call
; Convert the input to a number
mov eax, buf
sub eax, '0' ; convert the hundreds digit
mov ebx, 10
imul ebx
mov ecx, buf+1
sub ecx, '0' ; convert the tens digit
add eax, ecx
imul ebx
mov ecx, buf+2
sub ecx, '0' ; convert the units digit
add eax, ecx
; Read the 1-digit number
mov eax, 1 ; number of characters to read
mov ebx, 0 ; file descriptor (stdin)
mov ecx, buf ; buffer to store the input
mov edx, eax ; maximum number of characters to read
int 0x80 ; invoke the read system call
; Convert the input to a number
mov ebx, 10
mov ecx, buf
sub ecx, '0' ; convert the digit
mul ebx
; Subtract the 1-digit number from the 3-digit number
sub eax, ecx
; Convert the result to a string
mov ebx, 10
div ebx
add edx, '0' ; convert the units digit
mov [result+2], dl
div ebx
add edx, '0' ; convert the tens digit
mov [result+1], dl
add eax, '0' ; convert the hundreds digit
mov [result], al
; Print the result
mov eax, 4 ; system call for write
mov ebx, 1 ; file descriptor (stdout)
mov ecx, result ; address of the string to print
mov edx, 3 ; number of characters to print
int 0x80 ; invoke the write system call
; Exit the program
mov eax, 1 ; system call for exit
xor ebx, ebx ; exit status
int 0x80
section .bss
buf resb 4 ; buffer for input (3 digits + newline)
result resb 4 ; buffer for output (3 digits + null terminator)
Note that this implementation uses system calls for input/output and assumes that the input is terminated by a newline character. You may need to modify it to suit your specific requirements or platform.

You have just purchased a new Dell PowerEdge R820 Rack Server. The server is equipped with four Xeon E5-4650 CPUs, 128 GB of RAM, four 1 TB SAS hard drives, and two 750-watt power supplies. You have a 21-inch LCD monitor connected to your server. You want a UPS to keep your server running for up to 20 minutes in the event of a power failure. You prefer a rackmounted solution. Use the UPS selector tool at APC's Web site (a well-known UPS vendor). The UPS selector is at https://www.apc.com/shop/us/en/tools/ups_selector/
Determine which model of UPS will work well for this server, and state your reasons. Write a one-page memo explaining your choice and why this would work for the above situation. Upload the document here.
Answer:
To: Management
From: [Your Name]
Subject: UPS Recommendation for Dell PowerEdge R820 Rack Server
This memo is to recommend a UPS solution for the Dell PowerEdge R820 Rack Server. After considering the specs of the server and the desired use, I recommend the APC Smart-UPS RT 8000VA RM XL3U.
The Smart-UPS RT 8000VA RM XL3U is a rack mounted UPS designed for large applications. It has an output of 8000VA/5600W and can provide battery backup for up to 20 minutes. It has eight output receptacles, which should be enough to power the server, monitor, and any other peripherals that may be connected. The UPS also has a built-in web/network management interface, which allows you to monitor the UPS and its connected loads, as well as control the UPS remotely.
In addition, the Smart-UPS RT 8000VA RM XL3U can be configured with an optional external battery pack, which can provide up to 90 minutes of backup power. This is ideal for situations where an extended period of time without power is expected, such as during a blackout.
Overall, the Smart-UPS RT 8000VA RM XL3U is an excellent choice for the Dell PowerEdge R820 Rack Server. It is a powerful, reliable, and feature-rich UPS that can provide up to 20 minutes of battery backup and can be configured with an external battery pack for extended backup times.
If you have any questions or concerns about this recommendation, please do not hesitate to contact me.
