The predecessor of the internet is ARPANET better known as Advanced Research Project Agency
Answer:
C. 14.4 kwhr.
Explanation:
To calculate the energy used by appliance first calculate the power. The formulae for calculating power(<em>P</em>) is 
, where V stands for voltage and I stands for current.
In the given problem, V = 240 volts and I = 15 amp. Therefore,
Now, formulae for calculating energy used i.e. work(W) is 
, where <em>t</em> is the time.
In the given question time is 4 hr. Therefore energy used will be,
Energy used (W) = 
.
Answer:
ip = enrollment + section;
Explanation:
The variable ip has been declared to be a pointer to int.
int * ip;
The variable enrollment has been declared as an array of 20 elements .
int enrollment[20];
The variable section has been declared as an int.
int section;
In order to make ip point to the element in the array indexed by section, we can use the following statement :
ip = enrollment + section;
This will make ip point to enrollment[section].
Answer:
None of the mentioned options
Explanation:
- If we define a method in a derived class with same declaration type as that of base class then it is said to be overriding a function which behaves differently which will depend on the object which is calling the method.
- Option a,b and c are not any kind of methods we implement using coding.
- Option d is done when number or data types of parameters are different than the declaration of the base type.
Answer:
The correct answer for the following question is VLAN.
Explanation:
It stands for Virtue Logical Area Network which allows you to group port on a switch logically. VLANs can be extend across (a period of time) multiple switches means you used to express on port that you're in that VLAN by changing the VLAN number.
We have the ability to improve our security with VLANs by controlling what VLAN is accessing with the other network of VLANs. So that this network is particularly helpful in office situation to create subdomain without wiring physical domain as your network.
