Answer:Protects the local network from outside access
Explanation:Proxy is a type of serves as the mediator in computer network for connecting the network with the user system. These servers are responsible for maintaining the security against any unauthorized access in the system or internet,privacy and other functions.. It helps in protecting the whole network connection by taking the control at the servers .
Three characteristics of an ideal encrytion scheme are:
1. The encryption sheme should be strong: the algorithm is imprevious to direct attack and attempts are derived.
2. The encryption scheme should create unique ciphertext from the same plaintext for each key permutation, among other traits.
3. It should take at least millions of years to break ideal encryption scheme, based on mathematical predictions.
The term “Renaissance man” means for a very clever person to be good at many different things.
Answer:alphabetic keys, numeric keys, function keys and special keys.
Explanation:
Answer:
struct item
{
float previousCost;
float taxAmount;
float updatedCost;
} itemObject;
void calculation(int cost,int quantity,float tax)
{
struct item *itemPointer=&itemObject;
itemPointer->previousCost=(cost) * (quantity);
itemPointer->taxAmount=itemPointer->previousCost * (tax/100);
itemPointer->updatedCost=itemPointer->previousCost+itemPointer->taxAmount;
}
Explanation:
- Define a structure called item that has 3 properties namely previousCost, taxAmount and updatedCost.
- The calculation function takes in 3 parameters and inside the calculation function, make a pointer object of the item structure.
- Calculate the previous cost by multiplying cost with quantity.
- Calculate the tax amount by multiplying previous cost with (tax / 100).
- Calculate the previous cost by adding previous cost with tax amount.
