Binary numbers:
- Binary number is a number which is expressed in base-2 numeral system or binary numeral system.
- It uses only two symbols zero and one.
- It is mainly used by all modern computers and computer based devices.
- Each digit in binary numeral system is referred to as bit.
Hexadecimal numbers:
- Hexadecimal number system is a number system which consists of 16 digits and it is also known as base 16 number system.

Which statement regarding SGA_MAX_SIZE is true?
SGA_MAX_SIZE is modifiable after an instance is started, only when Automatic Memory Management is used.
SGA_MAX_SIZE is not dyamically modifiable.
SGA_MAX_SIZE is ignored when MEMORY_TARGET > 0.
SGA-MAX_SIZE must be specified when SGA_TARGET > 0

Missing one of the above might correspond to a non sufficient score for the project. More in details: 3.1 Separation of Logics The separation of logics has to be realizse by using…arrow_forward
- Write a C program to calculate the function sin(x) or cos(x) using a Taylor series expansion around the point 0. In other words, you will program the sine or cosine function yourself, without using any existing solution. You can enter the angles in degrees or radians. The program must work for any input, e.g. -4500° or +8649°. The function will have two arguments: float sinus(float radians, float epsilon); For your own implementation, use one of the following relations (you only need to program either sine or cosine, you don't need both): Tip 1: Of course, you cannot calculate the sum of an infinite series indefinitely. You can see (if not, look in the program) that the terms keep getting smaller, so there will definitely be a situation where adding another term will not change the result in any way (see problem 1.3 – machine epsilon). However, you can end the calculation even earlier – when the result changes by less than epsilon (a pre-specified, sufficiently small number, e.g.…arrow_forwardWrite a C program that counts the number of ones (set bits) in the binary representation of a given number.
