In its efforts to stand out from the rest of the pack, the Vivaldi browser now includes a full-fledged email client built directly into the web browser. The email client is complemented with a calendar and a feed reader, making the web browser more useful than ever. “The use of email is only increasing, and the way we use it is evolving,” wrote Jon von Tetzchner, co-founder and CEO of Vivaldi, in a blog post announcing the release....

With social distancing measures making it hard to get to open houses, virtual reality (VR) could be the next best thing to experiencing a new home in real life. Even before the pandemic, about 35% of buyers in 2017 made an offer on a home without seeing it in person, according to a report. The interest in new housing only has increased since then, as millions of people have fled large cities during the pandemic....

The particular case will depend on how the iPad is going to be used. The best minimum protection case is the Smart Case sold by Apple. It will protect the iPad from drops and help save battery life by putting the iPad in sleep mode when the cover is closed. This is a good case if the iPad will rarely leave home or is generally used in an office, airplane or hotel when traveling....

Overview of Formulas Formulas perform calculations in Excel. They always begin with the equal ( = ) sign, which is where you want the answer or results to appear. Formulas are great for working out “what if” scenarios that compare calculations based on changing data. Once you enter the formula, change only the amounts you need to calculate. You don’t have to keep entering “plus this” or “minus that,” as you would with a regular calculator....

How Does Lane Departure Warning Work? There are three primary types of lane departure warning technologies. While they all have the same general purpose, they achieve this goal in slightly different ways: Early lane departure warning systems typically used a single video camera to monitor lane markings, but modern systems can use visual, laser, or radar sensors. The methods that these systems use to provide corrective actions also differ from one situation to another....

How Frame Rate Works Digital video files, like film, are a collection of still images. The webcam’s frame rate determines how many still images go into making a video file. Higher frame rates deliver smoother video recording and streaming. However, these higher rates take more processing power and increase the file size of streamed and saved video content. Webcams with an fps rating of 15 or lower create a JPEG file of each still image and transmit these images in rapid succession....

Getting the Terms Right The term “cellphone” is interchangeable with the terms “cellular phone” and “mobile phone.” They all mean the same thing. The term “smartphone” means a cellphone that offers advanced features beyond calls, SMS messages, and basic organizer software. When people talk about mobile phones, “cellphone” is typically used to describe a simple feature phone. In contrast, “smartphone” describes advanced touch-screen phones. History of Cellphones Motorola developed the first commercially available cellphone between 1973 and 1983 and went on sale in the U....

Relational database management systems (RDBMS) implement the relational model of tables and relationships. Background on Database Management Systems The term DBMS has been around since the 1960s when IBM developed the first DBMS model called Information Management System, in which data were stored in a computer in a hierarchical tree structure. Individual pieces of data were connected only between parent and child records. The next generation of databases were network DBMS systems, which tried to solve some of the limitations of the hierarchical design by incorporating a one-to-many relationship between data....

The floppy disk was the primary method to transfer data between computers and back up files externally, from the late 1900s all the way up to the early 21st century. For the most part, the floppy disk drive is now completely obsolete. This older storage device has been replaced by other portable devices and built-in computer hardware not only because they’re more common and therefore compatible with other devices, but because they’re more capable and can store much more data....

Manual Retweets Explained A manual retweet involves copying and pasting another user’s tweet into the Compose new Tweet box and then typing ‘RT’ (which stands for retweet) before the tweet text, followed by the Twitter handle of the user who initially tweeted it. A manual retweet is a friendly way to give someone credit for a great tweet that gets reposted by someone else. For example, a manual retweet might look something like any of the following:...

What Are MoCA Networks? If you’ve ever streamed a TV show from your cable box or used a cloud-based DVR provided by your cable company to watch something you’ve recorded, you’ve already seen how a MoCA network works. The devices wire your router into your home’s coaxial networks. Then you can connect a second adapter to a media player directly to another coaxial port or a network extender to the port....

What Is a Text File? A text file is a file containing text, but there are several ways to think about that, so it’s important to know the kind of text document you have before dealing with a program that can open or convert it. Types of Text Files In the general sense, a text file refers to any file that has only text and is void of images and other non-text characters....

Web Directory vs Search Engine While the two are used to find content on the web, the primary difference is that links discovered through a search engine are gathered automatically while a web directory involves humans adding the links. The result of a web directory is an easily digestible list of links organized within common categories. A directory makes it easy to find websites by subject, whereas a search engine is useful for finding websites through keywords (or images if it’s an image search engine, or audio, etc....

One way to think of an external hard drive is as if it were a regular, internal hard drive that has been removed, covered in its own protective casing, and plugged into the outside of your computer. About External Hard Drives Internal hard drives can even be converted into external hard drives via what’s called a hard drive enclosure. External hard drives come in varying storage capacities, but they all connect to a computer either by USB, FireWire, eSATA, or wirelessly....

More Information on IP Packets The two main functions of the IP protocol are routing and addressing. To route packets to and from machines on a network, IP (the Internet Protocol) uses IP addresses which are carried along in the packets. The brief descriptions in the picture are meaningful enough to give you an idea of the function of the header elements. However, some might not be clear: The identification tag helps reassemble the packet from several eventual fragments....

Customers with an AT&T unlimited plan can talk, text, and use their plan data when traveling in Mexico or Canada with no roaming charge. Travelers to other countries receive roaming charges unless they turn off data roaming on their phone’s settings or if they sign up for an international calling and data plan....

Although a hard drive is usually the main device a user may want to boot from, other devices like optical drives, floppy drives, flash drives, and network resources are all typical devices that are listed as boot sequence options in the BIOS. How to Change the Boot Order in BIOS On many computers, the hard drive is listed as the first item in the boot sequence. Since the hard drive is always a bootable device (unless the computer is having a major problem), you’ll have to change the boot order if you want to boot from something else, like a DVD or a flash drive....

The terms IEEE 1394 and FireWire usually refer to the types of cables, ports, and connectors used to connect these types of external devices to computers. USB is a similar standard connection type for devices like flash drives and printers, cameras, and many other electronic devices. The latest USB standard transmits data faster than IEEE 1394 and is more widely available. Other Names for the IEEE 1394 Standard Apple’s brand name for the IEEE 1394 standard is FireWire, the most common term you hear when someone is talking about IEEE 1394....
