While this may seem like a simple, unneeded bit of information, knowing what operating system your Mac computer is using can help when you’re needing certain aspects of features – which often requires a certain version. If you have the wrong version, it may not work for you.
The OS software controls your entire computer, including memory and hardware devices like printers and drivers. It works with the CPU (central processing unit) to make sure your computer runs the best it can. The software and the hardware go hand-in-hand.
From there, you’ll see the overview of information, including the name and version. There are a plethora of names, including Catalina, Mojave, and High Sierra.
In order to get the most out of your Mac, make sure that your operating system is up to date with the newest version. This will allow security to be on top of its game. Simply click on the Software Update button and follow the prompts.

Yesterday, Microsoft began the Windows 10 build 19546 for the Fast ring Insiders. This update will be correcting a handful of known issues, such as Task View and Outlook Search problems. But they’re also launching a beta version of an Indexer Diagnostics app. This app was designed, “to help enhance your understanding of the capabilities of search, as well as increase the troubleshooting ability and support for general Windows Search issues,” according to the Windows Blog. The big deal in this Windows 10 build, though, is the upgraded calculator.
Back in August of 2019, Windows updated their calculator by giving it the capability of allowing it to switch it to “Always on Top” mode. Now, build 19546 is showing Fast ring Insiders the new graphing feature.
“Today, we’re updating Windows Calculator for Insiders with a preview of our new graphing mode. Adding support for graphing is one of our top feature requests in Feedback Hub, and we’re excited to bring this feature to our users. Graphing capabilities are also essential for students who are beginning to explore linear algebra. With this feature, we hope to empower students to learn mathematics by improving their conceptual understanding and attitudes towards math.”

For those Microsoft users who still use Windows 7, tomorrow marks the end of support. It was announced on their blog back in March of 2019, and in an updated post, they stated this:
Microsoft made a commitment to provide 10 years of product support for Windows 7 when it was released on October 22, 2009. When this 10-year period ends, Microsoft will discontinue Windows 7 support so that we can focus our investment on supporting newer technologies and great new experiences. The specific end of support day for Windows 7 will be January 14, 2020. After that, technical assistance and software updates from Windows Update that help protect your PC will no longer be available for the product.
If you’re running an activated copy of Windows 7 or newer, and need Windows 10, head over to the Download Windows 10 website. From there, you’ll click on the Download tool now and Run, shown under the Create Windows 10 installation media header. Simply follow the directions. Once the upgrade is finished, you can go to Settings Update & Security – Activation. You should be able to see a Windows 10 digital license.
Microsoft urges users that in order to have the safest experience, to keep your computer updated to the newest operating system.

In Windows 10, certain apps have the ability to run in the background so you don’t have to worry about them. This feature was put into place by Microsoft to allow notifications and app updates to users. However, there’s a large downside: battery consumption and possible data drainage. Thankfully, there is a way to control your background apps, if you prefer.
Here’s how to get there:
Go to Settings
Click on Privacy
Scroll down and click on Background apps
From here you can choose to turn on or off your option to allowing apps run in the background. Or, you can choose which apps you would rather not run in the background. This works well for those who need certain apps continuing to function.

Windows 10 2004, also known as 20H1, is heavily in the works and being tested within the Windows Insiders Program. The November update was a small update, but this one is planning on including a handful of improvements and features.
The name ‘2004’ was made for this update, instead of 2003. Brandon LeBlanc, the Windows Blog manager wrote, “Eagle-eyed Windows Insiders will notice that that as of this build, 20H1 officially shows it is version 2004. We have chosen to use 2004 as the version to eliminate confusion with any past product names (such as Windows Server 2003).”
Cortana is getting an upgrade! With both a light and a dark mode, you can also communicate with the digital assistant. There are operational improvements all around as well.
The Optional Update feature will be a thing. Next Spring, new drivers will only give you an optional update, and be under the ‘View Optional Updates’ on the Windows Update tab.
In the Optional Features, you will be able to see any information on all installations, along with selecting/cancelling multiple ones.

As an illustration, I’ll describe here in words how the various components in the disk interoperate when they receive a request for data. Hopefully this will provide some context for the descriptions of the components that follow in later sections.
A hard disk uses round, flat disks called platters, coated on both sides with a special media material designed to store information in the form of magnetic patterns. The platters are mounted by cutting a hole in the center and stacking them onto a spindle. The platters rotate at high speed, driven by a special spindle motor connected to the spindle. Special electromagnetic read/write devices called heads are mounted onto sliders and used to either record information onto the disk or read information from it. The sliders are mounted onto arms, all of which are mechanically connected into a single assembly and positioned over the surface of the disk by a device called an actuator. A logic board controls the activity of the other components and communicates with the rest of the PC.
Each surface of each platter on the disk can hold tens of billions of individual bits of data. These are organized into larger “chunks” for convenience, and to allow for easier and faster access to information. Each platter has two heads, one on the top of the platter and one on the bottom, so a hard disk with three platters (normally) has six surfaces and six total heads. Each platter has its information recorded in concentric circles called tracks. Each track is further broken down into smaller pieces called sectors, each of which holds 512 bytes of information.
The entire hard disk must be manufactured to a high degree of precision due to the extreme miniaturization of the components, and the importance of the hard disk’s role in the PC. The main part of the disk is isolated from outside air to ensure that no contaminants get onto the platters, which could cause damage to the read/write heads.
Exploded line drawing of a modern hard disk, showing the major components. Though the specifics vary greatly between different designs, the basic components you see above are typical of almost all PC hard disks.
Here’s an example case showing in brief what happens in the disk each time a piece of information needs to be read from it. This is a highly simplified example because it ignores factors such as disk caching, error correction, and many of the other special techniques that systems use today to increase performance and reliability. For example, sectors are not read individually on most PCs; they are grouped together into continuous chunks called clusters. A typical job, such as loading a file into a spreadsheet program, can involve thousands or even millions of individual disk accesses, and loading a 20 MB file 512 bytes at a time would be rather inefficient:
The first step in accessing the disk is to figure out where on the disk to look for the needed information. Between them, the application, operating system, system BIOS and possibly any special driver software for the disk, do the job of determining what part of the disk to read.
The location on the disk undergoes one or more translation steps until a final request can be made to the drive with an address expressed in terms of its geometry. The geometry of the drive is normally expressed in terms of the cylinder, head and sector that the system wants the drive to read. (A cylinder is equivalent to a track for addressing purposes). A request is sent to the drive over the disk drive interface giving it this address and asking for the sector to be read.
The hard disk’s control program first checks to see if the information requested is already in the hard disk’s own internal buffer (or cache). It if is then the controller supplies the information immediately, without needing to look on the surface of the disk itself.
In most cases the disk drive is already spinning. If it isn’t (because power management has instructed the disk to “spin down” to save energy) then the drive’s controller board will activate the spindle motor to “spin up” the drive to operating speed.
The controller board interprets the address it received for the read, and performs any necessary additional translation steps that take into account the particular characteristics of the drive. The hard disk’s logic program then looks at the final number of the cylinder requested. The cylinder number tells the disk which track to look at on the surface of the disk. The board instructs the actuator to move the read/write heads to the appropriate track.
When the heads are in the correct position, the controller activates the head specified in the correct read location. The head begins reading the track looking for the sector that was asked for. It waits for the disk to rotate the correct sector number under itself, and then reads the contents of the sector.
The controller board coordinates the flow of information from the hard disk into a temporary storage area (buffer). It then sends the information over the hard disk interface, usually to the system memory, satisfying the system’s request for data.
