Windows Screensavers Explained

Written by Roman Kramar

In this article you will find some background information about screensavers and their history. You will also learn how Windows screensavers differ from other programs and how you can use it to your own advantage. There are also some tips for screensavers users owning laptops, notebooks or CD-burning devices.

Have you ever asked yourself a question like "What is a screensaver actually?" I did. And now I will gladly sharerepparttar results of my investigation. As you can see easily, splittingrepparttar 107849 word "screensaver" into two words will give usrepparttar 107850 phrase "screen saver". This isn't a rocket science and it's clear thatrepparttar 107851 phrase suggests our subject somehow savingrepparttar 107852 screen. Sorepparttar 107853 word "screensaver" can be applied to some sort of good things that saverepparttar 107854 screen of our so much beloved baby-computer. But what does it mean exactly? Who is going to harm our computer's screen? Who could be such a bad person? The answer lies inrepparttar 107855 exact definition ofrepparttar 107856 screensavers.

If you are a meticulous person then you can searchrepparttar 107857 Internet and come up with some ofrepparttar 107858 existing definitions. But don't hurry. I will list some ofrepparttar 107859 most often found. Here they are:

- A moving picture or pattern that appears on your screen when you have not movedrepparttar 107860 mouse or pressed a key onrepparttar 107861 computer for a specified period of time. Screensavers prevent screen damage that is caused whenrepparttar 107862 same areas of light and dark are displayed for long periods of time.

- A program that "wakes up" after a certain amount of time has elapsed with no keyboard or mouse activity and blanksrepparttar 107863 screen or displays various moving objects acrossrepparttar 107864 screen; these are used to prevent your screen from getting "burn in".

- An animated picture or graphic that can be programmed throughrepparttar 107865 Display control panel to come onrepparttar 107866 computer screen after so much inactivity time has elapsed. The main reason for a screensaver is to reduce wear and tear onrepparttar 107867 CRT (Cathode Ray Tube) insiderepparttar 107868 monitor that can burn out or become etched ifrepparttar 107869 same window is left on for extended periods of time.

The picture is getting clearer, isn't it? Let's make it plain. The "burn in" or "damage" used in these definitions refer us torepparttar 107870 time before 90-ies. At that time many cathode ray tubes in TVs, computer monitors or elsewhere were prone to be damaged ifrepparttar 107871 same pattern (e.g.,repparttar 107872 WordPerfect status line;repparttar 107873 Pong score readout; or a TV channel-number display) was shown atrepparttar 107874 same position onrepparttar 107875 screen for very long periods of time. The phosphor onrepparttar 107876 screen would "fatigue" and that part ofrepparttar 107877 screen would seem grayed out, even whenrepparttar 107878 CRT was off.

TIP: Be careful when using a screensaver on a computer with an LCD screen (most laptops and notebooks). A pixel on an LCD screen is on when it's dark; therefore, blackingrepparttar 107879 screen as some screensavers do would cause more damage.

Eventually CRTs which were resistant to burn-in (and which sometimes went into sleep mode after a period of inactivity) were developed. But inrepparttar 107880 meantime, solution was found: home video game systems ofrepparttar 107881 era (e.g., Atari 2600s) would, when not being played, changerepparttar 107882 screen every few seconds, to avoid burn-in; and computer screensaver programs were developed.

The first screensavers were simple screen blankers - they just setrepparttar 107883 screen to all black, but, inrepparttar 107884 best case of creeping featurism ever recorded, these tiny (often under 1K long) programs grew without regard to efficiency or even basic usefulness. At first, small, innocuous display hacks (generally on an almost-black screen) were added. Later, more complex effects appeared, including animations (often with sound effects!) of arbitrary length and complexity.

And now we live inrepparttar 107885 world full of fun and entertaining screensavers. Many of them produce amazing and very attractive effects. You can find a screensaver on any theme you like, download it, install and enjoy.

This means that a typical screensaver is a program. And it really is. But isn't there something different? Is there something that distinguishes a program running as screensaver from other typical programs? You're right, there is a bit of mystery. In order to demystify it we should plunge deeper into screensavers' mechanics. But don't be afraid. It isn't complicated at all.

Backup - How to Avoid a Disaster

Written by Emil Malmberg

Creating backups of important files on a regular basis is probably one ofrepparttar easiest and cheapest ways to protect hours of work and personal files from all sorts of technical disasters. Still, billions of dollars are lost every year because of technical problems and loss of data. WinBackup is a new backup solution from LI Utilities that makes it easier for home users and small companies to create secure and well-organized data backups.

Organizing Backups by Priority When running backups on a daily basis it is very important thatrepparttar 107848 backup process does not interfere withrepparttar 107849 normal tasks performed on your computer. Running a large harddrive backup of all files on your pc can take anywhere from a few minutes to half an hour depending on how fast your computer is andrepparttar 107850 number of files that need to be copied. Since a backup operation will slow down your system considerably while in progress it is often necessary to split your backups into several backup jobs. By running more important jobs more often and by backing up static files less often you can easily reduce interference caused by backup operations by 90% or more. Not only will splitting and prioritising backups make your system run much smoother, but you will also be able to update important backups of emails and other data much more often.

Scheduling Backups In order to keep you pc backups up to date you will probably want to schedule backups to run automatically. WinBackup uses a built-in scheduler that makes this task very easy. Since WinBackup also supports any number of Backup Jobs with separate scheduling settings you can make more important jobs, like emails, run more often while large, infrequently updated, files are backed up only every other week or so. Using WinBackup you can even combine-scheduled backups with manual backups to ensure that important changes gets backed up immediately. Since you userepparttar 107851 same Backup Jobs for scheduled and manual file backups, running a manual file backup can be done with a single mouse click.

Compressing Data Backups In most cases, compressing backups can be a very good idea since many files that are commonly included in backups (emails, text documents or images) can often be compressed to 50% of their original size or less. If you are using WinBackup, compression is enabled by default. In WinBackup you can also find out how largerepparttar 107852 compressed file will be before runningrepparttar 107853 backup by looking atrepparttar 107854 estimated compressed size value. This value is updated in real-time while you add or remove files torepparttar 107855 backup and can be very helpful when determining ifrepparttar 107856 backup will fit onrepparttar 107857 target harddrive or cd.
