Answer:

Full back up

It creates complete copy of the source of data. This feature made it to the best back up with good speed of recovery of the data and simplicity.However, because it is needed for backing up of a lot of data, it is time consuming process,Besides it also disturbs the routine application of the technologist infrastructure. In addition large capacity storage is needed for the storage of the large volume of back up with each new creation.

Incremental back up: back up work at high speed thus saves time, Little storage capacity is needed. This type of back up can be run as many time as wished.

However, the restoration of data takes time, due to the time spent for restoration of initial back up and the incremental.

Differential Back up has very fast back up operation, because it only requires two pieces of back up.This is however slower compare to the Incremental.

The selective back up enable selection of certain type of file or folders for back up.

it can only be used to back up folders only when important data are needed only.Thus the storage capacity is low.

CPD eliminates back up window and reduces the recovery point objective.However, it has issue of compatibility with the resources to back up.,it is also expensive because its solutions are disk based.

Cloud based is affordable and save cost,It is easier to access. it is efficient,it can be access remotely for convenience.

However, Internet sources and some bandwidth must be available for access., always depends on third party providers,There is also problems encountered when switching providers.

Select the two true statements about functions with parameters:

kondor19780726 [428]

Answer:

Option (B) and (C) is the correct option to the following question.

Explanation:

Because the function is the module of the program and we call that function again and again anywhere whenever we need that function in the program.

Function is used to carry out any operation which is used in the program many times and it creates the program short and simple.

<u>For example</u>: if we need to add or multiply two numbers many times in the program then, we create one or two functions for addition and subtraction or one program for both, when we need them we call them.

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).
