On a computer that is provided with a desktop kind of user interface, wallpaper is the background pattern or picture against which desktop menus, icons, and other elements are displayed and moved around.
A wallpaper image can be in a JPEG or a GIF file format. Wallpaper is commonly used in Microsoft Windows, Macintosh Mac OS, Linux, and in other operating systems as well.
Each operating system provides several pre-installed wallpaper images for the user to choose from. A user can also choose to download and install third-party (Zedge App) wallpapers and use one of these instead.
Typically, a wallpaper image may be centered, stretched, or tiled. When an image is centered, it is placed in the middle of the desktop and is surrounded by a solid color.
When an image is stretched, it is stretched to cover all of the desktop. Only certain images can be stretched or they look distorted.
An image that is tiled is placed on the desktop much like tiles are placed in a shower or a tiled floor. Tiling is commonly used for patterns instead of photos because a pattern is one square image that repeats itself across and down the screen, effectively forming a single image.
What is Wallpaper?
Whenever a PC or a laptop is started, the picture that shows up on the monitor when the OS starts functioning is called the wallpaper. The user has the liberty to use the picture or photograph of his choice so that he does not get bored while working on the system.
It is like a cover of the system when it is in working position, and no file has been opened by you. Wallpaper is also called the desktop background though it is in the forefront, as it keeps on showing all the time on the computer when you are not working on the system.
It is possible to download pictures of almost anything under the sun from the net and to make it your wallpaper. All icons of folders and word files can be seen above wallpapers. Wallpapers serve no specific function apart from soothing your eyes.
What is Screensaver?
You must have observed your computer monitor going dark after there has been no activity on your part for some time. Normally, there is a graphic that is animated and keeps changing its position on the monitor that is visible to you.
This is called a screensaver, and if you have not set a screensaver, there is one by the OS set as default. If Microsoft XP is the OS being used by you, you will see an animated graphic displaying this name and jumping across the screen.
However, it is possible to download screensavers from the net and set them to be visible when the system remains untouched for a period of time that to can be set by the user.
Difference Between Screensaver And Wallpaper
Many new computer users confuse wallpaper with a screen saver, which is the moving picture or animation shown when you are away from your computer.
Screensavers and desktop wallpaper are both ways to personalize your desktop environment. While they have much in common, they fulfill very different tasks.
The most important difference is that a screensaver takes over your entire screen after a specified period of inactivity, temporarily replacing whatever was on your screen with an animation or a slideshow of images.
Desktop wallpaper, however, permanently acts as a background to your desktop, the screen that you see when your computer has finished starting up, or when your workspace is empty.
Screensavers Are Dynamic
The initial purpose of a screensaver was to tackle the problem of screen burn-in, the damage done to a computer display when a non-moving image, if left unchanged for a long period of time, would slowly be burned into the screen, leaving behind a permanent so-called ghost image.
By constantly changing the pixels used on the screen, for example by displaying a sequence of photographs, screensavers would prevent any image from appearing on the screen long enough to cause screen-burn.
As such, screensavers are dynamic by nature. At the same time, they allow you to instantly return to your desktop simply by moving your mouse or pressing a button on your keyboard.
Wallpaper is Static
As the images below demonstrates, your desktop wallpaper, sometimes called a desktop picture or background picture, is generally an unchanging image or pattern.
While it is possible to automatically rotate through multiple backgrounds on some operating systems, such as Windows Vista and 7, there is generally no inherent animation, and you can use practically any image as your wallpaper.
Considering that, for most of the time, you do not even see your wallpaper when you actively use your computer, any animation would be a waste of your computer’s resources
