Devices that are commonly jailbroken are the iPhone, iPod touch, and iPad, but many people are now jailbreaking devices like the Roku stick, Fire TV, and Chromecast. Jailbreaking an Android device is normally called rooting. Why People Jailbreak Phones Probably the most common reason to jailbreak a phone is to install custom apps that you couldn’t otherwise use on the phone. Apple blocks some apps from being released on the App Store, but jailbroken iPhones support sideloading or adding an app outside the manufacturer’s app store....
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.

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 ....
Advantages and Disadvantages of a Tweetstorm A Tweetstorm is series of tweets from one person that starts with a number and a slash. The first number is the order in which the tweet appears in a line of tweets covering a single topic. The number after the slash is the number of tweets from the same author. A Tweetstorm lets readers know how many tweets to expect. On the surface, this seems like a great idea, but it has gained some controversy....

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?
