Overall Findings Vector and bitmap images are both pictures on a screen, but they have different compositions and focuses. Bitmaps are made of pixels, while vector images are software-created and based on mathematical calculations. Bitmaps are not only more common in everyday life but are easier to use. You can quickly convert one format of bitmap image into another, and you can’t turn a bitmap into a vector without special software....
Why Is Waymo Developing Self-Driving Cars, and Who Will Use Them? Waymo’s stated mission is to “make it easy and safe for people and objects to move around.” The basic idea is that some people are really good drivers but a lot are not, and a world full of self-driving cars could potentially be much safer than a world full of human drivers. Whether or not that’s true, self-driving cars from companies like Waymo can be a tremendous asset for elderly or disabled drivers, as well as people who do not have a driver’s license....
What Are Animoji and Memoji? Animoji are an Apple feature that transforms specific emoji icons into short, customized animations using your facial expressions and voice. What’s particularly cool about these moving emoji is that they aren’t just animations. They scan your facial expressions and map them onto the emoji, so that an Animoji displays your behavior. For example, frown and your Animoji frowns. Shake your head, laugh, and close your eyes, and the Animoji does the same....
Generally, it refers to the types of cables (PS/2 cable), ports (PS/2 port), and other connectors used with these types of keyboards and mice. These ports are round and consist of 6 pins. In most cases, purple PS/2 ports are intended to be used by keyboards, while green ones are to be used by mice. This connection type was first introduced in 1987 with the IBM Personal System/2 series of personal computers....
There are a number of benefits torrent-based file sharing has over traditional file sharing. Expensive server equipment isn’t necessary to send files to many people at once, and low-bandwidth (slow) networks can just as easily download large sets of data. The most common way to use torrents is through a special file that uses the .TORRENT file extension. Within the file are directions for how to share specific data with other people....
Lithium-Ion Batteries Most modern laptops use lithium-ion batteries, the same as in many smaller consumer devices like watches and flashlights. These batteries charge hundreds of times without affecting battery life. Lithium-ion batteries feature an internal circuit that stops the charging process when the battery is fully charged. The circuit is necessary because, without it, the Li-ion battery could overheat and possibly burn as it charges. Nickel-Cadmium and Nickel Metal Hydride Batteries Older laptops use nickel-cadmium and nickel-metal hydride batteries....
What’s the Deal With Certain Numbers? Locations outside of the Americas use the number 14 and others to contact police, fire, and ambulance services in the case of an emergency. Not every country or region uses 911. Along with the number 14, numbers 15, 17, 18, and 19 are also used to contact emergency services in countries and regions such as Albania, Chad, Mali, Martinique, Morocco, Tahiti, etc. Other numbers like 01, 02, and 03 are used in Ukraine, Latvia, and Belarus for their emergency services....
What Is a DLL File? A DLL file, short for Dynamic Link Library, is a type of file that contains instructions that other programs can call upon to do certain things. This way, several programs can share the abilities programmed into a single file, and even do so simultaneously. For example, several different programs might all call upon the veryuseful.dll file (that’s made that up, of course) to find the free space on a hard drive, locate a file in a particular directory, and print a test page to the default printer....
In other words, a DNS cache is just a memory of recent DNS lookups that your computer can quickly refer to when it’s trying to figure out how to load a website. The Purpose of a DNS Cache The internet relies on the Domain Name System to maintain an index of all public websites and their corresponding IP addresses. You can think of it as a phone book. With a phone book, we don’t have to memorize everyone’s phone number, which is the only way phones can communicate: with a number....
The purpose of a hub is to form a single network segment on which all devices can communicate directly with each other. Until the early 2000s, Ethernet hubs were widely used for home networking due to their simplicity and low cost. While broadband routers have replaced them in homes, hubs still serve a useful purpose. What Is the Speed of a Hub? Ethernet hubs vary in their speed (network data rate, or bandwidth)....
Smartphones use battery capacities measured in milliamp hours. These capacities range between 2,000mAh and 5,000mAh, though there are occasional differences. Typical battery banks used for powering phones and laptops also have battery capacity measured in milliamp hours, which makes it easy to determine which size charger you need for a specific device. How Portable Chargers Work Instead of charging your phone, tablet, or another device from a wall outlet, you charge it from the power stored in the portable charger by inserting the charger (or charger cable) into the device that needs power....
All keys that are considered hives begin with “HKEY” and are at the root, or the top of the hierarchy in the registry, which is why they’re also sometimes called root keys or core system hives. To use a more common term, a hive is like a starting folder in the registry. Everything in the registry is ultimately contained in various hives. Where Are the Registry Hives Located? In Registry Editor, the hives are the set of registry keys that appear as folders on the left-hand side of the screen when all other keys have been minimized....
What Does a Server Do in a Computer Network? Although any computer running the necessary software can function as a server, the most typical use of the word references the enormous, high-powered machines that push and pull data from the internet. Most computer networks support one or more servers that handle specialized tasks. As a rule, the larger the network in terms of clients that connect to it or the amount of data that it moves, the more likely it is that several servers play a role, each dedicated to a specific purpose....
For example, the top-level domain of lifewire.com and google.com are both .com, but the TLD of wikipedia.org is .org. What Is the Purpose of a Top-Level Domain? Top-level domains serve as an instant way to understand what a website is about or where it’s based. For example, seeing a .gov address, like in www.whitehouse.gov, will immediately inform you that the material on the website is centered around government. A top-level domain of ....
What Is an ICS File? An ICS file is an iCalendar file. These are plain text files that include calendar event details like a description, beginning and ending times, location, etc. The ICS format is typically used for sending people meeting requests but also a popular means for subscribing to holiday or birthday calendars. Although ICS is much more popular, iCalendar files may instead use the ICAL or ICALENDER file extension....
LZMA files are similar to other compression algorithms like ZIP that compress data to save on space. However, LZMA compression is known to provide faster decompression times than other algorithms like BZIP2. LZMA2 is a container format that can hold both LZMA data and uncompressed data. There’s some more information below on their differences. TLZ is short for a TAR file that’s been compressed using LZMA. It uses the TAR....
Devices that you might think of as strictly hardware such as an optical drive, network card, TV remote, router, media player, camera, or scanner all have software that’s programmed into a special memory contained in the hardware itself. Where Firmware Updates Come From Manufacturers of CD, DVD, and BD drives often release regular firmware updates to keep their hardware compatible with new media. For example, let’s say you buy a 20-pack of empty BD discs and try to burn a video to a few of them, but it doesn’t work....
What Is mysqldump Used For? The mysqldump tool has you covered for both the server compromise and migration situations. Its basic function is to take a MySQL database and dump it out as a text file. But not any text file; the file is a set of SQL statements. These statements, when executed, reconstruct the database to the precise state it was in when the dump was executed. Use mysqldump to create exports of a database as backups, or when moving the database to a new host....
The Oculus Touch controllers are traditional controllers in their own right, complete with the analog sticks, buttons, and triggers needed to play most games. How Does Oculus Touch Work? Oculus Touch combines traditional game controller functionality with the motion tracking technology of the Oculus Rift. Each controller includes an analog thumbstick similar to those found on Xbox or PlayStation controllers, two face buttons that can also be pressed with a thumb, a trigger designed for the index finger, and a second trigger that is activated by squeezing the rest of the fingers against the controller grip....
This method of software delivery has risen to prominence alongside cloud computing. Even if you aren’t clear on what SaaS is, you probably use programs that fall under its definition. Some examples include Google Drive, Dropbox, and Microsoft Office 365. Here’s everything you need to know about SaaS, including how it works, why it won’t replace all of your software, and some of its risks. What Is SaaS? In SaaS systems, the software that runs on your computer—assuming it exists in that form—ties to a centralized host in the cloud....
