2. An event or action took place and it caused damage to data, hardware, software and processing capability of the computer. From the statement given, security risks are being described. Any event or action that is capable of causing a problem to a computer system is considered to be a security risk and should be prevented through the use of an appropriate utility software.

3. Virus is a software program that can infect, damage and disrupts the whole computer system.

4. To protect the whole computer system, the software utility which is needed is an Anti-virus.

5. To avoid losing valuable data to your computer, the most important thing to do is to regularly back-up your files.

Difference between implicit and explicit type casting

Lana71 [14]

Answer:

Implicit type casting means the type casting done by the compiler during compilation of program whereas Explicit type casting means the programmer explicitly type casts the variables. This is the difference implicit and explicit type casting.

Explanation:

Type casting means the conversion of one data type into another data type. There are two types of type casting. They are Implicit type casting and Explicit type casting.

Implicit type casting: The type casting which is done by the compiler during the compilation of a program. This occurs when we assigning smaller data type to larger data type and also both the data type are compatible. Below example clears the above concepts.

Ex: $int \, i = 10;$

$long \, l = i;$

In the above example " i " is " int " data type whereas " l " is long data type but as we assigned the value of " i " to " l ". Here " int " and " long " are compatible data types and we assigned smaller data type ( int - i ) to larger data type ( long - l ) implicit type casting occurs.

Explicit type casting: The type casting which is done by the programmer explicitly to convert one data type into other data type. If we want to assign a value of larger data type to smaller data type explicit type casting is required. Below example clears the above concepts.

Ex: $double \, d = 10.4;$

$long\, l = (long) d;$

In the above example " d " is " double " data type whereas " l " is " long " data type. Here we are explicitly type casting to change larger data value ( double - d ) to smaller data value ( long - l ).

Answer:

<h3>SWITCH CASE:</h3>

☆ STATEMENT WILL BE EXECUTED IS DECIDED BY USER.

Suppose you have a 16-bit machine with a page size of 16B. Assume that any unsigned 16-bit integer can be a memory address. Also

irinina [24]

Answer:

2^11

Explanation:

Physical Memory Size = 32 KB = 32 x 2^10 B

Virtual Address space = 216 B

Page size is always equal to frame size.

Page size = 16 B. Therefore, Frame size = 16 B

If there is a restriction, the number of bits is calculated like this:

number of page entries = 2^[log2(physical memory size) - log2(n bit machine)]

where

physical memory size = 32KB which is the restriction

n bit machine = frame size = 16

Hence, we have page entries = 2^[log2(32*2^10) - log2(16)] = 2ˆ[15 - 4 ] = 2ˆ11
