Wifi technology and the routers and wifi adapters using it have advanced a lot in recent years. It is difficult to explain the nuances of wifi technology without getting geeky, so bear with me a little as I attempt to explain some of the terminologies as simply as I can. Continue reading →

The use of voice-activated devices, smart TVs, and other smart devices, are becoming more and more common in our daily lives. So much so that we usually do not even give a second thought to reviewing the terms and conditions for privacy and security information when installing them, or bother to look at the relative settings when setting them up. Perhaps we are being a little too trusting of the companies producing the devices to look out for our best interests. Continue reading →

Kansas City area county health departments are all employing technology to help roll out the Covid-19 vaccinations. Below are links to websites and images of the areas for signing up to be notified when it is your turn to be vaccinated and the vaccine is available. Using your computer, tablet, or smartphone to sign up for notification is the most efficient method. Telephone numbers may be available also but may involve long wait times. These surveys are for notification only, not appointments for getting the vaccine. Continue reading →

There are some great free open source programs available that I consider good enough to not only recommend to beginners to try out, but that will satisfy the needs of most professionals. Of course, if you find a program useful and want to support the developer(s), you are encouraged to donate to them. Continue reading →

How fast is my internet connection? Am I getting what I am paying for? These are common concerns for consumers, especially if they think their internet connection is too slow. We will look at this from the top-down, starting with the service from the internet provider to the residence or business, then the modem/router that provides the local network over wire and wi-fi, and finally the adapters in the computer devices connected to the local network.

Solving Video Conferencing Camera and Microphone Problems
Because of privacy concerns, the use of cameras and microphones on electronic devices has become complicated. The operating systems (Windows, macOS, Android, iOS) have settings to either allow or block apps from using the camera and microphone. By default, they are initially blocked until you change the settings. If you access the video conferencing through an internet browser (Edge, Chrome, Firefox, or Safari for example), the privacy settings of the browser will also initially block access until you change the settings in the browser. This is often done when first accessing video conferencing through a browser when a message appears for you to either allow or block access to the camera or microphone (two separate messages). Doing so will change the browser settings for you, but sometimes you just get a message that says you need to change your browser settings to allow access. Continue reading →

Some members have been wanting us to talk about television/internet/phone service providers in the area. It is a very complex subject because they all have advertised promotional prices for bundled packages that do not include a lot of other fees, taxes and other extras that apply, nor do they advertise what the normal price will be after the introductory rate for the first year or two that it typically lasts.

Many of you know that Microsoft Office apps such as Word, Excel, PowerPoint and OneNote are available as individually downloadable apps for free in the Android Play Store and Apple App Store for tablets and phones. If you only use one app, such as Word, that may still be your preference, but if you would rather have more of the Office suite available through one single app, you can now have it that way for both Android and iOS. Just search for Microsoft Office in the store and select the app called Microsoft Office: Word, Excel, PowerPoint & More and make sure it is from Microsoft Corporation. After downloading and installing the app, it will appear as a red on white icon simply called Office. If you have a white on red icon called Office Mobile that looks similar, that was just an old link to get you to download the individual products. I uninstalled that app from my phone to avoid confusion. Continue reading →

Short Message Service (SMS) has been used since 1992 for sending text messages over mobile phone carrier service. It is limited to 160 text characters per message. Some enhanced message services were developed that could handle up to 1600 characters per message, but a real advance in capability came into use after about 2005 with Multimedia Messaging Service (MMS). This expanded the capability of text messages to also contain files such as photos, videos, audio and documents. The data limit per message was initially 300 KB and then later increased to 600 KB, which is not enough for high resolution photos or video so they are compressed into smaller, grainier images. Since internet servers are utilized for storage and transfer of data between carriers, MMS is not real-time. Another breakthrough has begun to be rolled out in 2019 with Rich Communication Services (RCS). Theoretically the data limit per message is over 10 GB, but in practice may be limited to something less by the carrier service used. Continue reading →

Does using HTTPS (secure HTTP) make internet browsing on public wi-fi safe?
Currently just a little over half of websites use HTTPS only in their designs. Others may use it to establish the initial connection with the user and then revert to HTTP for displaying some content to avoid the extra burden of encrypting/decrypting data. Some allow initial connection with HTTP and then redirect to HTTPS. This opens up opportunities for a “man in the middle” interception of the non-secure transmission and redirecting it to the attacker’s own content. Continue reading →

Free Backup & Recovery Software Worth Trying
The File History feature in Microsoft Windows 10 or Time Machine for Apple macOS are fine for automatically backing up user files to another hard disk drive (HDD) or solid state drive (SSD), but should your main drive with your operating system and program files suddenly die, it is very convenient to have a recent backup of your complete system that can be restored quickly and easily onto a replacement drive.
The System Image Backup in Windows can be used, but it is not very simple to get to, often fails to complete when performed, is terribly slow, and a pain to find the backup VHD file to explore the contents. Continue reading →

A friend recently asked what I thought about signing into a site using your Google or Facebook account credentials rather than creating an account for that site. I have not chosen to do that myself because of concerns about the data that could be shared between the sites and what they might do with it. It got me thinking that maybe it would be good to do some research on this and other password security questions that frequently come up. Let’s look at four common questions: Continue reading →

Lately SenCom has been asking members what type of device they think they will be using the most for their computing over the next few years- desktop, laptop, or tablet. Statistics on global sales of computing devices at https://www.statista.com/statistics/272595/global-shipments-forecast-for-tablets-laptops-and-desktop-pcs/ show a shift from desktops to laptops as the main device, while tablets sales have been decreasing. Projections for new sales of each over the next few years are almost flat. Comments by SenCom seniors show preference for devices with larger displays and keyboards, which generally favor desktops.

Most people now use an Ethernet capable printer that is connected to their home network either by wire or wirelessly. There are several easy methods available to also print from a mobile device such as a smartphone or tablet to a printer when both are connected to the same home network. Even if you are using a USB only printer connected to a computer on the home network, your mobile device can still be set up to print to it as long as the computer and printer are on and available when you want to print. I just set up my Android phone to print to a USB printer connected to a desktop computer by using Google Cloud Print. Continue reading →

Windows 10 was released in July 2015. Many older computers manufactured as far back as 2007 were upgraded to Windows 10 during the free upgrade period. All seemed well until the feature updates were rolled out twice per year and difficulties in updating the old computers began to surface. Being stuck at one of the feature update versions for the remaining life of the old computer would be more tolerable if not for the limit of only 18 months of security updates Microsoft provides for each feature update version.

Chromebooks were introduced in 2011 as low cost alternatives to Windows and MacOS computers. They run the Google Chrome OS using either Intel or ARM processors. The goal was to make computers and the internet available to the masses for under $200. The first Chromebooks were a little pricier than that and had very few capabilities as a computer without being connected to the internet. Since then, Chromebooks have become available from sub-$200 models up to $600 or more for high-end models. Continue reading →

Many low budget laptops and small desktop computers are provided with very low performance processors, such as the Intel Celeron or Pentium models or the older pre-Ryzen AMD models. Even some of the older Intel i3 processor models are very low performance. You will probably become aware of the performance limitations when trying to use the computer while it is running a scheduled antivirus or antimalware scan, or when Windows updates are being automatically downloaded in the background. You may notice that the computer becomes painfully slow at doing more than one task at a time. Continue reading →

Point of use surge protectors, usually in the form of a power strip, are probably used by most of us for at least some of the more sensitive or costly electronic items in our households. Did you know that your surge protector has likely been subjected to multiple surges if it is over two or three years old and may have diminished or even no protection left? If it has an indicating light, usually red, to indicate the protection is working, then there is at least some protection left in it. This is different than a light in the on/off or reset switch that only shows if it has power or not. Continue reading →

Microsoft is no longer supporting the System Image Backup feature of Windows 7 that was carried over to Windows 10 and plans to eventually remove it in a future update of Windows 10. Few people were using it and often had trouble using it when they did. There are many third party programs that are easier to use, have more features, and are available in both free and paid versions. We will take a look at some of the best and most popular programs available for Windows and also macOS, as using Apple’s Disk Utility to create a system image backup is no picnic either.

Internet browsers have recently begun displaying red warning pages about potentially unsafe websites you are about to navigate to. Google analyzes keywords and attributes found on the page that might indicate danger and flags the site in a database that is also used by some other browsers for their warnings. It is possible for a site to be flagged as dangerous that is not, and Google will investigate and remove a listed site from the database if requested to do so, though it may take some time for that to happen.
