Answer:
You need to understand all the network typologies and the devices that we use in the Computer networks. You also use the techniques like routing, masking, firewalls, VPN, as well as the network protocol. And recently added is the PKI. And hence you need to make sure that you know all these, and you should also know ipv4 and ipv6. Rest you can consult Tanenbaum for further studies on Computer Network.

Answer:
In assembly language, two instructions control the use of the assembly language procedure.
CALL pushed the control to the return address onto the stack and transferred the control.
RET instruction returns the address that placed on the stack by a call instruction.
Explanation:
Action RET instruction
- The RET instruction pops the address and returns off the stack, which is pointed by the stack pointer.
- The stack is LIFO in memory at a particular location, and the pointer points offset from the stack location.
RET instruction does its job by consulting the register and memory state at the point when it is executed.
In RET instruction, only register and memory state is executed. Call instruction must save that address that figure out in a register and memory location.
Answer:
The formula does not require arguments.
Explanation:
One of the programs or software that runs on a computer is Microsoft Office programs. One of these programs is called Microsoft Excel. It is a spreadsheet program where calculations can be made, graphs, diagrams can be plotted and drawn as well.
In other to utilize Microsoft Excel properly, we make use of what we call FUNCTIONS. Functions in Microsoft Excel are defined as formulas, that have already been prepared or created before hand in the Microsoft Excel program so that we can be able to used Microsoft Excel properly and efficiently. Functions may or may not require ARGUMENTS to carry out necessary calculations.
An ARGUMENT is a number or variable that functions require to carry out or do their calculations.
Examples of the functions found in Microsoft Excel are the TODAY and NOW functions. These two functions are used in spreadsheets on Microsoft Excel with regards to Date and Time.
TODAY function is used to give us or update the current or present date while the NOW function gives us or updated the current date and time.
The uniqueness or similarities between the TODAY and NOW functions is that their formula do not require arguments.
Answer:
#include <iostream>
using namespace std;
class Str{ ///baseclass
public :
string super_str;
string getStr()
{
return super_str;
}
void setStr(string String)
{
super_str=String;
}
};
class str : public Str{ //inheriting Str publicly
public :
string sub_str;
string getstr()
{
return sub_str;
}
void setstr(string String)
{
sub_str=String;
}
bool notstartswith()
{
int n=sub_str.length(); //to find length of substr
bool flag=false;
for(int i=0;i<n;i++) //Loop to check beginning of Str
{
if(super_str[i]!=sub_str[i])
{
flag=true;
break;
}
}
return flag;
}
};
int main()
{
str s; //object of subclass
s.setStr("Helloworld");
s.setstr("Hey");
if(s.notstartswith()==1) //checking if str is substring of Str
cout<<"Str does not start with str";
else
cout<<"Str starts with str";
return 0;
}
OUTPUT :
Str does not start with str
Explanation:
Above program is implemented the way as mentioned. for loop is being used to check the beginning of the str starts with substring or not.
