how to check if serial interface is dte ot DCE?
If you can see the DTE/DCE cable, you can tell by looking which router has the DCE interface connected to it - the letters "DTE" or "DCE" will either be molded into the connector itself, or if it's an older cable there should be a little piece of tape on the cable that tells you what the interface type is.
Assume the data link protocol used by NDAS has the following associated characteristics:
An 8-bit ASCII code is used. Each frame has a size (length) of 11936 bits. A half-duplex circuit with a speed of 1 million bits per second is used for transmission. There is a 30-millisecond turnaround time on the half-duplex circuit. Each frame contains 20 overhead (non-user-data) bytes. Assume that the probability of a frame requiring retransmission due to error in transmission is 1 percent. A millisecond is one-thousandth of a second. Also, 8 bits = 1 character = 1byte
Fill in the blanks
K= _________ bits per bytes
M=_________ bytes
C= _________ overhead bytes
Answer:
The transmission speed = 0.278 MB/s
Explanation:
K = 8 bits
M = 11936/8 bits = 1492 bits
transmission rate R = 1000000/ 8 = 125000 bps
overhead bytes C = 20
probability = 0.01
time T = 30 ms = 30 x10^-3 s
The data transmission speed formula = K(M-C)(1-p) / (M/R) + T
= 8( 1492 - 20)(0.99)/ (1492/125000) + 30 x10^-3
= 0.278 MB/s

Group of answer choices.
a. web surfing.
b. email, texting, and social networking.
c. e-shopping.
d. word processing.
e. management of finances.
Answer:
b. email, texting, and social networking.
Explanation:
Communication can be defined as a process which typically involves the transfer of information from one person (sender) to another (recipient), through the use of semiotics, symbols and signs that are mutually understood by both parties. One of the most widely used communication channel or medium is an e-mail (electronic mail).
An e-mail is an acronym for electronic mail and it is a software application or program designed to let users send texts and multimedia messages over the internet.
Also, social media platforms (social network) serves as an effective communication channel for the dissemination of information in real-time from one person to another person within or in a different location. Both email and social networking involves texting and are mainly done on computer.
Hence, the leading use of computer is email, texting, and social networking.

Driving is expensive. Write a program with a car's miles/gallon and gas dollars/gallon (both doubles) as input, and output the gas cost for 20 miles, 75 miles, and 500 miles. Output each floating-point value with two digits after the decimal point, which can be achieved by executing cout << fixed << setprecision(2); once before all other cout statements.
Answer:
Explanation:
The following is written in C++ and asks the user for inputs in both miles/gallon and dollars/gallon and then calculates the gas cost for the requested mileages using the input values
#include <iostream>
#include <iomanip>
using namespace std;
int main () {
// distance in miles
float distance1 = 20.0, distance2 = 75.0, distance3 = 500.0;
float miles_gallon, dollars_gallon;
cout << "Enter cars miles/gallon: "; cin >> miles_gallon;
cout << "Enter cars dollars/gallon: "; cin >> dollars_gallon;
cout << "the gas cost for " << distance1 << " miles is " << fixed << setprecision(2) << (float) dollars_gallon * distance1 / miles_gallon << "$\n";
cout << "the gas cost for " << distance2 << " miles is " << fixed << setprecision(2) << (float) dollars_gallon * distance2 / miles_gallon << "$\n";
cout << "the gas cost for " << distance3 << " miles is " << fixed << setprecision(2) << (float) dollars_gallon * distance3 / miles_gallon << "$\n";

Consider the regular expressions:
R1 = (01)* (0*1*) (10)
R2 = (101)* (01)*
R3 = (10) (01*)*(01)
R4 = 10(R2*)|R3
Recall that, for a list of regular expressions, the function getToken() returns the next token from the input that matches one of the regular expressions. If there is more than one match, the longest match is returned. If there is more than one longest match, the token with the longest match that appears first in the list is returned. If there is no match, ERROR is returned. If the function getToken() is called once on input 1000101, it will return:
a. R1
b. R2
c. R3
d. R4
e. ERROR
Answer:
c. R3
Explanation:
For R1;
there are 10 matches, after these 10 no matches occur again
for R2;
this also does not match more than 10 as we have in R1
for r3;
R3 has the longest match. Its matching can be done 1000101 times.
for r4;
The whole of r4 can be matched.
Error;
we cannot have an error because matches exist.
so in answer to this question we pick R3 as the solution because there are more than one longest march and the one returned in the list is that which appeared first. R3 came first
In this exercise we have to use computer knowledge to identify which is the correct sequence of code that best corresponds to the given question, in this way we have that the correct alternative is:
[tex]c. R3[/tex]
So analyzing the first alternative, we find;
For R1, there are 10 matches, after these 10 no matches occur again.
So analyzing the second alternative, we find;
For R2, this also does not match more than 10 as we have in R1
So analyzing the third alternative, we find;
R3 has the longest match. Its matching can be done 1000101 times.
So analyzing the fourth alternative, we find;
For R4, the whole of r4 can be matched.
So analyzing the fifth alternative, we find;
Error; we cannot have an error because matches exist.
So in answer to this question we pick R3 as the solution because there are more than one longest march and the one returned in the list is that which appeared first.

Your co-worker who went to UCLA tells you that DHCP is not enabled at your new job, so you should just use the same IP address that you have at home to connect to the internet. He told you it should work because your computer is communicating with a unique public IP address at home, so no other computer in the world would have it. When you try this, your computer does not have internet access. Give two reasons why?
Answer:
1. internet connection is not enabled on the computer.
2. The DHCP server in the company is not enabled as well.
Explanation:
For a user to access the internet, the computer must have a public IP address that is either assigned to it by a service provider or dynamically from the DHCP server in the computer. In the case of the former, the user just needs to enable the internet connection to obtain the unique IP address.
If the DHCP server or the internet connection is not enabled, the user would not have access to the internet.
differentiate between a university and a TVET college in terms of what each offers and explain the stigma associated with TVET colleges
Answer: See explanation
Explanation:
The main focus of a Technical Vocational Education and Training (TVET) college is to prepare the students and train them so that they'll be functional in a skilled trade. It focuses on vocational training and education. University isn't really concerned about transfer of skills but rather more concerned with the transfer of knowledge to the students
The Technical Vocational Education and Training (TVET) qualification is also faster, cheaper and easier to get than the university certificate which is costlier and takes longer period to get.
The stigma associated with TVET colleges has been created by both the society and the government. Firstly, people believed that only those from poor backgrounds or those that couldn't gain university admisson go to TVET colleges.
Also, the government isn't helping matters as public funding for education are allocated more to universities and not really allocated to TVET colleges. These has brought about the stigma to the TVET.
The difference between a university and a TVET college in terms of what each offers is university impact knowledge while TVET college is more of practical.
University and TVET collegeThe major difference is University provide students with knowledge the need based on the course they are studying while TVET colleges is more of practical as they provide the students with practical skills they need because they render technical and vocational education and training.
The stigma associated with TVET colleges is because people think that University student has higher opportunities when in labor market than TVET colleges student.
Inconclusion the difference between a university and a TVET college in terms of what each offers is university impact knowledge while TVET college is more of practical.

X274: Recursion Programming Exercise: Cannonballs Spherical objects, such as cannonballs, can be stacked to form a pyramid with one cannonball at the top, sitting on top of a square composed of four cannonballs, sitting on top of a square composed of nine cannonballs, and so forth.
RequireD:
Write a recursive function that takes as its argument the height of a pyramid of cannonballs and returns the number of cannonballs it contains.
Answer:
The function in C is as follows:
#include <stdio.h>
int C_ball(int height){
if(height == 1) {
return 1;}
return (height * height) + C_ball(height - 1);}
int main(){
int n;
printf("Height: ");
scanf("%d",&n);
printf("Balls: %d",C_ball(n));
return 0;
}
Explanation:
The function begins here
#include <stdio.h>
This defines the function
int C_ball(int height){
If height is 1, return 1
if(height == 1) {
return 1;}
This calls the function recursively
return (height * height) + C_ball(height - 1);}
The main begins here
int main(){
This declares the height as integer
int n;
This prompts the user for the height
printf("Height: ");
scanf("%d",&n);
This calls the function
printf("Balls: %d",C_ball(n));
return 0;
}
Bugs always seem to creep into programs and code. What strategies have you learned to find bugs more easily and crush them with a fix?
The process involves in finding bugs as well as crushing them in a debugging process is extensive and this can consist of following process;
Examination of the error symptoms
identifying the cause of it
fixing of the error.
This process is usually required a large amount of work, Although no precise procedure that is set in for fixing all error, but some useful strategies that use in reducing the debugging effort.
One of the significant part of this process is localizing of the error, which is figuring out the cause as well as the symptoms. Strategies that I have learnt in finding and fixing the error in the process of debugging includes;Incremental as well as bottom-up program development; development of the program incrementally remains one of the most effective ways that can be used in localizing the error, often testing as the piece of code is added, so with this it will be easier to find the error since any error is from the last piece of code added.And also since the last fragment of the code will be small then searching for bugs won't take much time to find and debug.Bottom-up development helps in maximizing the benefits that comes from incremental development. With bottom-up development, after successful testing of a code, it's behavior will not change once another piece is added to it, since existing code will never replied on new part so it will be easier to trace error in the new code and fix it.Instrument program can be used to log information and there can be insertion of print statements.Instrument program using assertions; Assertions can be used in checking if the program actually maintains the properties or those invariant that the code relies on, Because the program will definitely stops once the assertion fails, and there is actuality that the point where the program reached and stops is closer to the cause, as well as good indicator of how the problem looks like , then the bug can then be fixed.breakpoints can be set in the program as well as stepping and over functions, then watching program expressions, as well as inspection of the memory contents at a particular point during the execution can give the needed run-time information.Backtracking: this option works in a way whereby one will need to start from the point that the problem occurred then go back through the code to to detect the issue, then the bug can then be fixed.Binary search: this is exploration of the code by using divide and conquer approach, so that the the bug be pin down quickly.Therefore, Bugs are treat to programs and they can be dealt with using discussed methods.

Def locate_substring(dna_snippet, dna): This function takes in two strings, dna_snippet and dna, where dna_snippet is a substring of dna, and returns all locations of the substring as a list of integers. In other words, dna_snippet may exist in multiple locations within dna; you should return the beginning index position of each occurrence of dna_snippet inside of dna. Example: * Sample DNA snippet (substring): "ATAT" * Sample DNA string: "GATATATGCATATACTT" * The returned position list: [1, 3, 9]
Answer:
In Python. The function is as follows:
def locate_substring(dna_snippet, dna):
res = [i for i in range(len(dna_snippet)) if dna_snippet.startswith(dna, i)]
print("The returned position list : " + str(res))
Explanation:
