private static void add() {
int b = a+20;
System.out.println(b);

What is the decimal equivalent of 11BA?
allsm [11]

Answer:

To convert hexadecimal number 11BA to decimal, follow these two steps:

Start from one's place in 11BA : multiply ones place with 16^0, tens place with 16^1, hundreds place with 16^2 and so on from right to left

Add all the product we got from step 1 to get the decimal equivalent of 11BA.

Using the above steps, here is the work involved in the solution for converting 11BA to decimal number (Don't forget that we start from ones place to so on...)

Decimal equivalent of "A" = (A) 10 × 16^0 = 10

Decimal equivalent of "B" = (B) 11 × 16^1 = 176

Decimal equivalent of "1" = 1 × 16^2 = 256

Decimal equivalent of "1" = 1 × 16^3 = 4096

Decimal equivalent of "11BA" = 409625617610

11BA = 4538

Here is the final answer, The hexadecimal number 11BA converted to decimal is therefore equal to:

4538

ruslelena [56]

Answer:

The five rules are described as follows:

Rule A permits the inbound Simple Mail Transfer Protocol (SMTP) connection.

Rule B permits the inbound Simple Mail Transfer Protocol (SMTP) connection.

Rule C permits the outbound Simple Mail Transfer Protocol (SMTP) connection.

Rule D permits the outbound Simple Mail Transfer Protocol (SMTP) connection.

Rule E does not perform any action. Thus it is when the action is denied.

Explanation:

Rule A allows information transfer of the incoming email from the external server to the internal remote server, thus this allows an inbound connection.

Rule B allows information transfer of the incoming email from the remote server to the external remote server, thus this allows an inbound connection.

Rule C allows information transfer of outgoing email from the external server to the internal remote server, thus this allows an outbound connection.

Rule D allows information transfer of the outgoing email from the remote server to the external remote server, thus this allows an outbound connection.

Rule E does not allow any action in either direction thus it is when action is denied.

prisoha [69]

Answer:

Abstraction is the process of removing or taking away certain characteristics to reduce or hide several very important characteristics.

In OOP (Object Oriented Programming), to increase efficiency and reduce complexity, a programmer hides certain vital data about an object. This is abstraction in programming.

For further clarification, a programmer ensures that the name given to an entity makes sense and most importantly, that it carries relevant aspects, and non essential parts are not included.
