What Is the Main Function of a Modem? A modem is your entrance to the internet. Because it translates the data for you, it’s a form of interpreter converting the signal from your ISP to a universal one your computer and other devices can understand. That applies whether you use a cable provider such as Comcast, fiber optics from FIOS, satellite such as Direct TV, or a DSL or dial-up phone connection....
For example, if a password field is case sensitive, then you must enter each letter case as you did when the password was created. Any tool that supports text input might support case-sensitive input. Where Is Case Sensitivity Used? Examples of computer-related data that is often, but not always, case sensitive include commands, usernames, file names, programming language tags, variables, and passwords. For example, because Windows passwords are case sensitive, the password HappyApple$ is only valid if it’s entered in that exact way....
A file that’s marked as read-only usually implies that it shouldn’t be altered or that great caution should be taken before making changes to it. Other things besides files can also be read-only, like particularly configured flash drives and other solid state storage devices like SD cards. Certain areas of your computer memory may also be set as read-only. What Types of Files Are Usually Read-Only? Aside from the rare situation where you, or someone else, has manually set a read-only flag on a file, most of these types of files you’ll find are important ones that your operating system needs to start properly or, when changed or removed, might cause your computer to crash....
What is a Network Media Player? Many are not familiar with the term “network media player.” To make matters more confusing, manufacturers may give this device different names like “digital media player,” “digital media adapter,” “media player,” “media extender.” TVs and home theater components with added capabilities to find your media and play it, add more confusion. These home theater devices may simply be called a smart TV, internet-enabled Blu-ray Disc player, or networked audio/video receiver....
The Advantages of PCIe SSDs Over SATA Drives Interfaces on a computer motherboard operate at different speeds. Just like the internal components of a computer communicate faster than something connected over USB, there are different bandwidth limits to internal interfaces. SATA has been the main interface used to connect hard drives to a motherboard for several years. It works well, and with conventional magnetic-platter hard drives, SATA can’t max out its transfer capabilities....
The alternative to a bitmap is a vector image, which instead of dots use embedded instructions to draw lines on paths. A vector may be infinitely resized with no loss in image quality. All About Pixels Each pixel on your screen is, in very simple terms, a “bit” of color information used to display the image on a screen. That screen could be as small as the one on an Apple Watch or as large as a pixel board found in Times Square....
By default, when you execute a command, the input comes from the keyboard and the output is sent to the Command Prompt window. Command inputs and outputs are called command handles. Redirection Operators in Windows and MS-DOS The table below lists all the available redirection operators for commands in Windows and MS-DOS. However, the > and » redirection operators are, by a considerable margin, the most commonly used. The clip command is worth mentioning here as well....
The term SATA generally refers to the types of cables and connections that follow this standard. Serial ATA replaces Parallel ATA as the IDE standard of choice for connecting storage devices inside of a computer. SATA storage devices can transmit data to and from the rest of the computer much, much faster than an otherwise similar PATA device. SATA vs PATA Compared to Parallel ATA, Serial ATA also has the benefit of cheaper cable costs and the ability to hot-swap devices....
What Makes Up a Windows Theme? Windows computers ship with a theme already in place. Many users opt for the default configuration during installation or setup, and thus, the most common elements are applied automatically. If changes are made during the setup process, those changes become part of the saved, edited theme. This saved theme and all of its settings are available in the Settings window. Here are a few options as they apply to both the Windows theme and the Windows 10 theme that are applied during set up:...
Types of Cloud Computing Service providers create cloud computing systems to serve common business or research needs. Examples of cloud computing services include: Virtual IT (information technology): Configure and deploy remote external servers as extensions to a company’s local IT network. Software: Use commercial software applications, or develop and remotely host custom-built applications, Network storage: Network storage archives data across the internet to a provider without needing to know the physical location of storage....

What Causes the Screen Door Effect? Displays like computer monitors, televisions, phones, and VR headsets all use pixels to display images. Each pixel is set to a specific color and brightness such that, when viewed together at an appropriate distance, the viewer perceives an unbroken image. If the viewer moves too close to a pixel-based display, they will eventually be able to make out the individual pixels and the space between the pixels....
Before you get started, make sure all equipment is turned off, including the subwoofer. You never want to connect or disconnect any cables while anything is on, lest something incurs accidental damage. If Nothing Works, Consider Replacing Your Subwoofer If the subwoofer doesn’t power on at all, or it powers on but won’t play a thing, then there’s a good chance that it is defective and needs to be replaced....
The complaint accuses Facebook of entrenching itself in the lives of billions of people by absorbing competitors and behaving in a generally anti-competitive way. Alabama, Georgia, South Carolina, and South Dakota are the only states that failed to join. The landmark antitrust suit seeks to split up Facebook, Instagram, and WhatsApp, alleging that Facebook’s acquisition of the latter two was an attempt to quell competitors and keep consumers from more privacy-focused alternatives....
Apple stores are amazingly open, inviting, and easy to use. You can walk in at any time and start trying things out, without having to ask a surly store clerk to take the sole demo unit out of the locked display case. But the same open-plan can also be viewed as a minimum-security venue with high-value, easily-grabbable goods just laid out there on tables, ready to snatch and run. The catch is, most of those devices will be useless if stolen....
The only way to fix it so that your cigarette lighter fuse stops blowing is to check each possible point of failure until you identify the issue. But whatever you do, don’t even think about replacing the cigarette lighter fuse with a higher amp fuse. Depending on the nature of your problem, replacing the fuse with a higher amp version could damage the fuse box, melt wires, or even cause a fire....
Normally, small speakers equal smaller sound. Those little speaker cones just can’t shift as much air as a bigger cone, which usually leads to a thinner sound, with less bass. Or smaller speakers manage to extend their bass with clever tricks, like rear-opening bass ports, or complex sound-shaping tubes inside. This helps, but the result can be flabby, or unfocused. These iLoud speakers use a mixture of clever design, digital processing, and an included room calibration microphone to create a sound that rivals huge speakers with even 8-inch drivers....
With its incredibly slim design, I plan to use the iMac as a gigantic laptop. After all, at only 10 pounds, it weighs about the same as some gaming laptops. And, since, like many people, I’m working from home these days, I don’t need to tote a real portable very often. You Can’t Have Too Much Screen I am a multitasking fiend, often running six programs at once along with dozens of tabs as I switch between emails, messaging, and researching and writing stories....
