All You Need to Know About File Associations

A computer knows how to use tens of thousands of different document types because it has an index that tells it which applications are associated with file types. More than one application can be related to each file format. For example, PhotoShop and Microsoft Paint are equally useful for opening .jpeg documents. But only one of them could be the “default program”. Depending on the Windows version, you can use a utility called “Standard Programs” to manage file relationships on your computer. Some people want to change the file associations in their windows. By doing some research, you can learn How to Change File Associations in Windows 7, 8, 10. In this article, we will talk about the things you need to know about file association.

Why Do File Associations Break?

Computers are all living machines that are continually changing. It is not unusual to install a new program and accept its default settings. The only problem is that some installers are programmed to change the computer settings so that the new program becomes the default application for certain types of documents. For example, when a new image editing program is installed, it can suddenly become the default setting for almost any image type. This might be fine if you want the program and want to use it widely.

How Do You Fix Broken File Associations?

On the other hand, it might not be very pleasant if you prefer to use another program most of the time. Besides, your computer might not have the ideal applications to open certain types of documents. In this case, you’ll have to convert the document into a format that your PC can manage or find applications that can work with it.

How to Set the Default Application?

Setting the default application is relatively easy. You can right-click on a document with the desired length and follow some simple instructions to change the default application or launch the “Default Applications” utility directly. If you work with only one document, right-click it and select Open from the list that appears. Find the correct application, select it, and then check the box to create the selected program by default for that type of file. Confirm your selection by clicking OK, and the institution will be created.

The next technique would be to start the default programs directly. Once found, click on the link “Assign a document type or protocol to a specific program.” In the list, find the extension you need to connect to and then select it. In addition to this standard application, you will find a short description. If you want to change the default setting, click on the “Change program” button and scroll to the desired program.

What You Probably Don’t Know about UHF Shortwave Radio

What You Probably Don’t Know about UHF Shortwave Radio

Various types of the radio have been invented throughout times. The aim of developing the radio relates to helping humans work. There is a radio type that has a certain frequency, called UHF. UHF has the frequency 430 MHz corresponds to a radio wave of 70 centimeters. UHF has less than other high-frequency waves as a radio. The frequency 144 MHz corresponds to a radio wave of two meters in length. The UHF radio spectrum is about one gigahertz. It makes this type of radio can have more impacts on humans.

The frequency paid by UHF radios has been extended from 400 to 470 MHz. The primary UHF radios appeared in the 512 MHz bands, then 800-960 MHz. UHF radios usually have a load capacity of several watts. UHF radios have long been a widely used long-range medium.

UHF Radio

Benefits of UHF

One of the main advantages of UHF portable radios is their portability. Also, its signal can be transmitted by an external antenna. However, portable radios are not as suitable for handling interference in the same frequency group.

Mobile radios that can be mounted on a person’s dashboard have frequency scanning capabilities similar to those of a portable radio. UHF radios are not affected by solar activity. They operate only in all weather conditions.

This type of radios is very famous because they are sometimes mounted around a ring antenna that can be several inches in diameter and several meters in diameter. It is why UHF radios are very popular among amateur radios.

Restriction of UHF

The lower end of the UHF bands, unlike other frequencies, is less susceptible to digital sound; for example, the lower UHF bands are less vulnerable to interference from nearby power lines or microwaves. The same is especially true for television broadcasts in mountain regions. It makes it almost impossible for most companies to use UHF radios without a frequency license.

Many government agencies and courses have allocated UHF for some functions. Other districts have been delegated the entire range of UHF frequencies in the United States, except for a few rings reserved for amateur radio.

Another restriction of UHF frequencies is that they are often in the line of sight. If someone comes to a pond, his portable UHF radio may not work until he receives it from the canyon. However, UHF signals can go further if they bounce off the ionosphere.

Progression of UHF

UHF radios have difficulties with interference from local TV stations, which rely on UHF and RFID, which use UHF and other frequencies. For example, UHF radios use the 400-470 MHz frequency range, but 433 MHz is unique to RFID.

UHF portable radios are gradually being replaced by VHF radios in public safety with the development of technology. The FCC is taking advantage of this “narrow band” by rejecting new systems that do not meet the narrowband requirements.

Any portable radio, repeater, or base station that does not meet these narrowband requirements loses its operating license; the only alternative is redesign and replacement with attenuated hardware.

Pros of Buying Li-Ion Batteries

Most devices, like laptops and smartphones, can’t function with no batteries. Lithium-ion batteries also have become crucial in electro-mobility since it’s currently the battery life of choice. There are various sorts of lithium-ion cells; one example is the samsung green. The principal difference between them lies in their cathode materials. Different lithium-ion batteries provide various attributes between power, lifespan, price, and functionality. In this guide, we’re likely to acquire an insight into the benefits provided by these batteries.battery icons

Voltage Density

Greater energy density is just one of the significant benefits of purchasing this kind of battery. Many of today’s electronics, such as cellular phones, call for constant voltage supply, and such devices use up a great deal of energy. So, for all these devices, you will need batteries that contain a greater energy density. The greater energy density of those batteries is the significant benefit you’ll be able to use your device for long hours before the battery drains out.

Self-Discharge

Self-discharge is among the usual issues that lots of rechargeable batteries have. The fantastic thing about lithium-ion batteries is they feature a lesser rate of release compared to other batteries. Normally, their self-discharge speed is only 5 percent during the first two or three hours after charge. Thus, you do not need to be worried about their release rate.

No Major Maintenance

batteriesAnother benefit of those batteries is they require little to no upkeep for optimum performance. On the flip side, Ni-Cad cells need to be recharged periodically. Because this does not impact lithium-ion cells, so you do not have to stick to any maintenance procedure.

Some rechargeable cells have been made that they must get primed for initial usage. Nonetheless, this isn’t true with lithium-ion cells and batteries. Thus, you do not need to fret about priming cells. In brief, if you’re thinking about purchasing a battery to satisfy your particular requirements, we recommend that you get lithium-ion batteries since they offer you a good deal of benefits.
