Makovka662 [10]3 years ago
8 0

Answer:

Let our mask be 1010000...000. Notice that, if we apply XOR operation to any number with this mask, the first and third bits will be complemented and all other bits will be unchanged. Since for each individual bit, XOR with 0 does not change the value of bit and XOR with 1 changes the value of bit.

Explanation:

To give a hexadecimal number, we should know the number of bits in representation of number.

Which daemon manages the physical memory by moving process from physical memory to swap space when more physical memory is neede
Anastasy [175]

Answer:

Swap daemon

Explanation:

Swap daemon manages the physical memory by moving process from physical memory to swap space when more physical memory is needed. The main function of the swap daemon is to monitor processes running on a computer to determine whether or not it requires to be swapped.

The physical memory of a computer system is known as random access memory (RAM).

A random access memory (RAM) can be defined as the internal hardware memory which allows data to be read and written (changed) in a computer.Basically, a random access memory (RAM) is used for temporarily storing data such as software programs, operating system (OS),machine code and working data (data in current use) so that they are easily and rapidly accessible to the central processing unit (CPU).

Additionally, RAM is a volatile memory because any data stored in it would be lost or erased once the computer is turned off. Thus, it can only retain data while the computer is turned on and as such is considered to be a short-term memory.

There are two (2) main types of random access memory (RAM) and these are;

1. Static Random Access Memory (SRAM).

2. Dynamic Random Access Memory (DRAM).
