DPI (Dots per inch), which is the resolution/detail that the printer can print.
Paper size, as you may want to print on a large range of media
Paper type, as conventional printers would print on standard paper, whilst different uses, such as photography, would benefit from printing on higher quality photo paper.
Connectivity, this can range from wireless over WiFi or Bluetooth, wired over Ethernet or USB, or even where you may have to connect a USB/SD card directly into the printer. All of these data transmission solutions would result in their own constraints and benefits.

Importance of backup in system administration:
Backups are crucial in system administrations for preserving continuity and protecting against specific types of hardware failures, service interruptions, and human mistakes. To aid a company in recovering from an unexpected catastrophe, backup copies make it possible to restore data to a previous point in time. To safeguard against primary data loss or corruption, it is essential to save a copies of data on a different media. When a system administrator create a backup, he makes a copy of the data that you can restore if your main data is lost. These errors may be the consequence of faulty hardware or software, corrupted data, or a human error like a targeted attack or an unintentional deletion. System backup and recovery is therefore a crucial skill for system administrators as well as the companies they work for.
Three methods for performing backup:
- Disk image: A efficient method to back up not only the files and directories but also everything else on the system is by creating a disk image. If a user have a disk image, the user can restore everything, including the operating system, applications, data, and more, so the user won't have to worry about any difficulties. Placing the disk image-containing DVD into the DVD-ROM to restore the backup. Additionally, just attach an external HDD to the computer if the user have a disk image that they made.
- External hard drive: The most common backup method is to use an external hard drive or even a USB flash drive. An HDD can be easily, quickly, and affordably backed up. It is effective since consumers may carry their portable backup with them wherever they go.
- Cloud backup: Cloud backup or Online backup has been around for a while, but not many people really utilize it. But the greatest backup technique by far is cloud backup. The user does not have to worry about hardware problems because their files are saved in the cloud and can be accessed from anywhere because the backups are automatically produced and everything is synchronized. It is one of the greatest methods to backup, especially when you consider that the contents are encrypted and stored securely.
Answer:
1. The output is 0
2. Each element in the array is initialized to 0.0
Explanation:
Solving (a): The output of the code
We have:
<em>int numbers[4] = { 99, 87 }; </em>
<em>cout << numbers[3] << endl;</em>
<em />
The first line initializes the 0 and 1 index of the array to 99 and 87, respectively.
Other elements will be 0, by default.
So, the following code segment will output 0
<em>cout << numbers[3] << endl; </em>
<em />
Solving (b): What the given code will do?
The first and second line declares an array of 5 elements
However, the following iteration will only initialize the array with 0.0 starting from the second
<em>for(int i = 2; i <= SIZE; i++) { x[i] = 0.0; }</em>
<em />
Because, the counter is initialized to start from the second index.
<h2>This function will land up in infinite function call</h2>
Explanation:
first time when the function gets invoked,
f(6,8), so k=6 & n=8, inside the function it checks k==n, ie. 6==8, returns false, then one more if is available, so 6>8 is check for , once again it is false and else loop is executed, the function is called recursively using f(k-n,n), that is f(6-8,8), it means f(-2,8) is passed.
Second time,
if(-2==8) is false, so if(-2>8) is again false and function f(-10, 8) is called
if(-10==8) is false, so if(-10>8) is again false and function f(-18,8) is called
if(-18==8) is false, so if(-18>8) is again false and function f(-26,8) is called
So this goes recursively and ends in an infinite function call.
