Answer:
The data-link layer
Explanation:
The physical layer and data-link layer are often confused a lot especially in terms of what they do in the TCP/IP 7 layer protocol. The physical layer as the name suggests represents the physical devices like the cables and the connectors that join or interconnect computers together. This layer is also responsible for sending the signals over to other connections of a network. The data-link, on the other hand, translates and interprets these sent binary signals so that network devices can communicate. This layer is responsible in adding mac addresses to data packets and encapsulating these packets into frames before being placed on the media for transmission. Since it resides in between the network layer and the physical layer, it connects the upper layers of the TCP/IP model to the physical layer.
Answer:
Programming & Software Development
Explanation:
Software development life cycle (SDLC) can be defined as a strategic process or methodology that defines the key steps or stages for creating and implementing high quality software applications.
Some of the models used in the software development life cycle (SDLC) are;
I. A waterfall model.
II. An incremental model.
III. A spiral model.
Also, programming refers to a software development process which typically involves writing the sets of instructions (codes) that are responsible for the proper functioning of a software.
In this scenario, Brian is a computer engineer who writes security software for a banking system.
Thus, the pathway in the Information Technology career cluster that Brian's job falls into is Programming & Software Development.
Answer: in C
#include <stdio.h>
int main(){
int num1, num2;
printf("Enter first number :: ");
scanf("%d", &num1);
printf("Enter second number :: ");
scanf("%d", &num2);
if(num1 > num2){
printf("%d is larger than %d\n", num1, num2);
} else if (num2 > num1) {
printf("%d is larger than %d\n", num2, num1);
} else{
printf("Both of them are equal\n");
}
return 0;
}
