Software vs Application: Let’s Discuss the Difference How about software vs application? To make it easier we are going to start by knowing a little bit more about what software is. In simple understanding software is a terminology that is used to called computer part which is not tangible. The tangible component of computers. In short everything else in your computer that makes it able to run any data processing is software. So, is application part of software? In fact application is part of software. But, not all software’s are application. Basically application is a particular software that performs particular …
Comparison Between Impact Printer and Non-Impact Printer Impact Printers An impact printer makes contact with the paper. It usually forms the print image by pressing an inked ribbon against the paper using a hammer or pins. Following are some examples of impact printers dot-matrix printer, daisy-wheel printer, Line printers, drum printer, chain printer, band printer. Non-impact Printers Non-impact printers do not use a striking device to produce characters on the paper; and because these printers do not hammer against the paper they are much quieter. Following are some non-impacted printers Ink-jet printers and laser printer. We summarized all the differences between impact printer and non-impact printer regarding to …
Signs Your Hard Drive Lifetime is Ending & What To Do
Every one of us owns precious files like personal documents, photos, videos, or audio files, and we typically store them on hard drives. Few people realize that most electronic storage devices, including hard drives, have a rather limited lifetime when compared to the ancient ways of storing information, such as stone, papyrus, paper, or old school records. The average lifetime of a stationary hard drive today is around 5 – 10 years, depending on the type and manufacturer, and it rapidly declines if the drive is subject to strong variations in temperature, humidity, and motion as in not being stationary.
Since a majority of people today own laptops and external hard drives, which get dragged around quite a bit, a realistic hard drive lifetime is probably around 3 – 5 years. This is an extremely short time to reliably store important data. In the best of cases, hard drives fail gradually, giving you the chance to react, get a copy of your data, and replace the storage device before facing a fatal failure. There are a host of signs that hint to a gradual failure of your hard drive. If you are unsure how much life is left on your hard drive, read this article to find out what signs may reveal an approaching failure.
Slowing Down Computer, Frequent Freezes, Blue Screen Of Death
These are very unspecific signs that can be caused by a million different things. However, regardless of what the issue behind these symptoms is, it is recommended that you immediately make a backup. If these problems occur after a fresh installations or in Windows Safe Mode, it is almost certain that it is due to bad hardware, and possibly a failing hard drive.
If you’re beginning to find files that fail to open and are corrupted even though they saved without errors or if files suddenly disappear, you should get worried. While again this could be due to a multitude of issues, it is also a typical sign for a gradual hard drive failure.
Accumulation Of Bad Sectors
Bad sectors are areas of the hard drive that do not maintain data integrity. They are automatically masked by the operating system and thus hard to identify, especially if large amounts of the disk are currently in use. If you actually run into bad sectors, however, that certainly is a bad sign.
You can run a manual disk check to identify errors that Windows has not spotted, yet. In Windows 7, go to > Start > Computer and right-click on the disk or partition you wish to check. Select > Properties, in the window that opens switch to the >Tools tab and click > Check now… In the Checking Disk window place a checkmark next to > Automatically fix file system errors and > Scan for an attempt recovery of bad sectors.
When you hear strange noises coming from your hard drive, it may be too late already. A repetitive sound also known as the click of death is caused by the head as it is trying to write data and recovers from errors in doing so. Grinding or screeching noises indicate that parts of the hardware, for example the bearings or spindle motor, are failing.
There are tools that aim to predict hard drive failure by reading the S.M.A.R.T. (Self-Monitoring, Analysis and Reporting Technology) data that is recorded by the operating system. Unfortunately, like most other methods listed above, S.M.A.R.T. is notoriously unreliable in predicting hard drive failure and the catastrophe will often happen before the warning of S.M.A.R.T. kicks in. If you have a working hard drive, however, and would like to have a look at its S.M.A.R.T. data, check out this article – 4 Tools To Predict and Prevent Hard Drive Failure
Hard Drive Is Failing, What Shall We Do?
So you are worried that a hard drive failure is just around the corner? The truth is, even if you are not worried, it is! The only thing you can do is always keep backups of your data on a second hard drive. The likelihood that both drives will fail simultaneously are very rare. An exception would be natural disasters like floods or fires. For these cases, I recommend to keep a copy of your most important data in a different physical location, for example at work or with a friend, or possibly on a remote server, for example by using an online backup solution.
Do not rely on signs or software to tell you whether you have a failing hard drive. It is more likely than not that it will fail unexpectedly and without any warning signs whatsoever. Rather than trying to forecast something that is even less predictable than the weather, you should rely on backups.

How to start Windows 7/8/10 in safe mode
What is Windows safe mode?
First, let’s start with what Microsoft has to say about safe mode:
“Safe mode starts Windows in a basic state, using a limited set of files and drivers. It can help you troubleshoot problems on your PC. For example, if the problem doesn’t happen in safe mode, you’ll know default settings and basic device drivers aren’t causing the issue.”
Thanks, Microsoft. However, for the average computer user, that explanation might not make the most sense. Here’s how to understand safe mode in a few points.
