Safety When Using Public WIFI

How can we ensure the security of our data when using public WiFi?

Most people are unaware that free public Wi-Fi isn’t protected by encryption. Your online actions aren’t always safe, even if you have to provide a password to get in. Your online personal data is at danger if you connect to a public Wi-Fi network without using proper security measures.

Connect to websites using HTTPS, which encrypts all data sent to and received from the website throughout the connection process. The difference between HTTPS and VPN is that HTTPS encrypts all of your communication whereas VPN encrypts only the communication to and from a certain website.

Check the address bar of your browser window to see whether you’re connected using HTTPS; you should see the letters “HTTPS” at the beginning of the site URL if you’re connected using HTTPS. Additionally, in some web browsers, you may notice a lock icon.

On top of that, you can protect your data by using two-factor authentication wherever feasible. This kind of application (such as Authy) mandates the usage of a password as well as a secondary code that is updated on a regular basis for websites and apps. Attackers are constantly on the move, searching for loopholes to access personal information. Thankfully with two-factor authentication, there is no way hackers would get the secondary code even if your password is obtained.

Microsoft Edge 2nd Popular Browser

Despite the fact that Microsoft Edge is not a new browser, many Windows users are only now becoming aware of the most recent version. The Microsoft Edge web browser has a number of unexpectedly brilliant features that should put it in the running to be your primary internet browser.

With a market share of up to 10%, Microsoft Edge has surpassed as the second most popular desktop browser. Chrome is still the most popular browser, with 67 percent of the market, but Safari has slid to third place, just ahead of Mozilla’s Firefox browser. StatCounter provides the data for these stats.

According to WindowsLatest, “As per April 2022 market share report, Microsoft Edge has now crossed the 10% share in browser market. While Google Chrome lost its 0.65 share and its coverage dropped to 66.64%, Edge added 0.42 points and now has 10.07% share.”

It’s worth noting that numerous enhancements have been made to the Microsoft Edge browser in the last several months. Give it a try and see for yourself.

How to Increase Download Speeds

If your computer speeds are lagging, here are a few ways you can try to increase productivity.

You may run a speed test online to find out how fast your download and upload speeds are in reality. If the test results appear to be positive, see that there isn’t anything downloading or uploading in the background that might be affecting the performance speed.

Checking to see whether the manufacturer of your network card has released a new driver and installing it may assist to accelerate downloads. If there is nothing downloading or uploading in the background and there is no network card update, resetting the router and modem may be necessary to resolve the issue. It may be beneficial to disconnect the power cord from the router or modem for 1-2 seconds.

Even if you are still experiencing connectivity issues, you should call your Internet service provider to see whether the problem is on their end or on yours. Your service provider will have the opportunity to re-establish the primary connection if the situation warrants it.

New Windows 11 Feature Available

A new dedicated feature coming to Windows 11 has tech blogs talking. Named “Voice Clarity”, this particular newcomer is being tested to some PC’s, but not all.

According to WindowsLatest, “Unlike Teams noise cancellation, which is baked into the Teams app, Microsoft’s new Voice Clarity feature works at the OS level and it aims to capture the entire audio spectrum of your audio at higher bandwidth.”

For now, it’s said Voice Clarity only works on Surface laptop Studio, but will hopefully start rolling out to other devices soon.

A Brief Insight of File Extensions

Following the last period in a file name, a series of characters known as the file extension, or file name extension, is used to identify the file and locate it in the file system.

For example, the file extension “.txt” is the same as the word “txt” in the dictionary. As soon as you double-click on a file, the extension informs the version of windows about the sort of file you are opening and the software you want to run.

Aside from the fact that it must begin with a period and have at least one letter, there are no additional formatting requirements for an extension. In most cases, file extensions are made up of three characters, which can be either letters or numbers, and which textually describe the type of file being referred in the text. Text files, mp3 files, jpeg picture files, and files compressed using the gzip application are all signified by the file extensions.txt,.mp3,.jpg, and.gz. Text files, mp3 files, jpeg picture files, and files compressed using the gzip application are all denoted by the file extension.txt.

Text files, mp3 files, jpeg picture files, and files compressed using the gzip application are all denoted by the file extensions.txt,.mp3,.jpg, and.gz. The file extensions.txt,.mp3,.jpg, and.gz denote text files, mp3 files, jpeg picture files, and files compressed using the gzip application, respectively.

This information is contained inside the extension’s real name. It shows you what sort of file is being referenced to and where it is located.

Change Default Browser on Windows 11

Microsoft appears to have grown particularly active in pushing its own programs over the default apps installed before to the update in its latest version of Windows. If you updated to Windows 11, you may find Microsoft Edge is the default browser.

Changing Windows 10 default applications are quite easy. However, according to The Verge, “the process for changing your defaults in Windows 11 has become more complicated than it was in Windows 10. So you may not get that handy request — or if you do, it may land you on a complicated-looking page headed App > Default apps.”

Here’s how to change your default browser on Windows 11:

  1. Go to Settings > Apps > Default apps
  2. Type in preferred browser name (Firefox, Chrome, etc.)
  3. Click on “Set default”

If you’d prefer your file and link types to coincide with the same browser, you can change those as well.

What if files or applications are missing?

The fact that something isn’t saved where you expect it to be doesn’t always indicate that the application or document you’re looking for is no longer available to you. Erroneous clicks can cause folders and files to be dropped into locations where they were not intended to be.

First, make sure you haven’t mistakenly deleted any files or shortcuts by checking your Recycle Bin. If the object you’re looking for happens to be in there, delete it immediately before accessing it or saving any modifications to it.

Next, take a quick peek at your taskbar to see if the application or document you’re looking for is already running.

The final option is to simply put the name of the application or file into the Search Box on the taskbar, which is clearly displayed next to the Windows button. If you’re looking for a certain document or spreadsheet, you may also utilize File Explorer to locate it. In Windows, choose the folder icon from your taskbar and type anything into the search box at the top right of the window that appears.

Aside from that, the Word and Excel programs in Microsoft Office also include a “open recent” option that is really useful. All you have to do is click the File tab, then “Open,” and either Recent Documents (in Word) or Recent Workbooks (in Excel) will be the default selection. If your lost file is located somewhere else, such as on OneDrive, you can utilize this navigation window to locate it.

Low Resolution on Desktop

It can be frustrating, indeed!

When you restart your computer, you may notice that the resolution has changed or that desktop icons and text have been shortened. Your workspace is in a bit of a jumble.

It’s possible that it’s due to a problem with your video card. Many times, all that is required is an update to your graphics drivers. You can easily go to the manufacturer’s website and download the most recent software for the device. Look on your graphics card for the make and model.

If completing this step does not resolve the problem, it’s likely that there are more serious problems with your hardware.

You may need to replace the graphics card entirely in order to resolve the problem. However, in the vast majority of situations, the problem is caused by software. Karls Technology can help you figure out the solution to your problem.

Check Out Time Machine on macOS

Time Machine is a tool on Macs that allows you to recover files if you accidentally delete them. Throughout the day, the function takes several photos of your macOS device.

Using this built-in backup feature, you can ensure that all of your personal data is safe and secure.

Time Machine automatically makes hourly backups for the past 24 hours, daily backups for the past month, and weekly backups for all previous months. The oldest backups are deleted when your backup disk is full. The first backup might take a long time, but you can continue using your Mac while a backup is underway. Time Machine backs up only the files that changed since the previous backup, so future backups will be faster.

Source: Apple

Here’s how to access Time Machine:

  1. Go to System Preferences
  2. Search for Time Machine
  3. Checkmark the Back Up Automatically, or set up your preferred backup disk

Resetting Your Computer Without Losing Data

Resetting your PC might be useful for a variety of reasons. It is a smart alternative if you have frequent issues with its performance. If you’re experiencing problems with your computer’s software, a reset may be the best option.

If you’re seeking for a specific remedy for a specific problem, it may not always be effective or generate the desired results. Resetting your Windows 11 machine may be an option in this situation. It is possible to lose all of your data when you reset your computer. However, the truth is rather different. Here’s how to do it:

If you go to Settings —-> System —-> Recovery, troubleshooting can begin by clicking the ‘Fix problems without resetting this PC’ banner, which will open a new window. If you’ve done this and it didn’t work, go to Reset PC. Select “Keep my files” in the popup that appears. Click on “Remove everything” from the menu if you want a fresh start for your computer.
