A computer appliance is an electronic device that provides resources for software applications. It can supplement the capacity of a computer with additional memory, or it can serve as a replacement for an old system. Some of these devices are directly connected to the hard drive, while others require a network connection or are powered by an internal battery. Some of the more common appliances are discussed below. They all share similar functions, but may differ a bit in function. One example of a computer appliance is a computer printer. These devices are usually powered by a wall outlet, and…

A data hierarchy is a system for organizing and storing data. The organization of data typically takes a hierarchical format, with fields, records, and files arranged on a level higher than the lowest. Using a data hierarchy as a starting point for understanding data is essential to the successful management of information systems. There are many benefits of this system, including the ability to manage and share large amounts of data, as well as its many applications when combined with a data bottleneck solution. A data hierarchy starts with a general top level of categories and works downwards to a…

A video game emulator is software that simulates the capabilities of a video game console. It lets you play games that were developed for one system on another, without having to buy the original console. Typically, these programs are free and easy to use, and can be set up in a matter of minutes. There are emulation programs for almost every type of gaming console. The older the console, the more likely there will be an emulation program for it. An emulator works by emulating the hardware of a particular gaming system and is often used to relive classic games.…

A flexible keyboard is ideal for mobile users, and can even be used in places where you don't want your computer to be visible. This type of keyboard is bendable and can be connected to your notebook without having to worry about a plastic case. It also has a natural feel and can easily be cleaned with a damp cloth. It's also a good choice for people who prefer typing on a flat surface. A flexible keyboard can be folded or rolled up to fit any space and type. When folded, they're designed to add very little depth to your…

What is a legacy port? It's a type of connection that's old or obsolete. Most modern computers still have legacy ports but only one. These ports were developed for specific hardware and are considered to be partially superseded by newer types of interfaces. USB technology was introduced in 1998 and replaced many of the older ports. USB is a universal hardware connection standard that offers faster data transfer rates and better power. Most desktop computers have one or two legacy ports. A legacy port is obsolete. A replacement port will provide the same functionality that legacy ports did, but in…

What is cloud computing? Cloud computing is a type of internet architecture that makes computer systems available on-demand, especially data storage and processing power. This means that the user does not have to manage the resources directly. Large clouds typically have functions distributed across many locations, each of which serves as a data center. For example, a business might need a server in New York City, but would like to have the same service anywhere. Cloud computing allows organizations to easily move their workloads and services to the cloud without affecting existing infrastructure. This is a great benefit because it…

A network relay is a device that separates a larger network into multiple smaller networks. This allows one-way broadcasting of variable changes between them. This device is often used in modular YOLOL systems, where a single wireless network connects to several wireless networks. The concept behind a network relay is very simple. It consists of a number of smaller, connected computers that are linked together by a shared physical interface. A relay network functions like a chain of people. The sender is at the beginning of the chain and the recipient is at the end. The people in between are…

On-The-Fly encryption is a method for converting data without the need to decrypt it before sending it. It is particularly useful in situations where transparency is important and there's a need to prevent unauthorized access to confidential information. It is a powerful encryption tool that's commonly used on mobile devices and portable storage devices. However, it isn't widely used because the majority of users don't know much about computers or cryptography. On-the-Fly encryption works by automatically encrypting and decrypting files when they're stored on a hard drive, SSD, or other type of removable storage device. Unlike the traditional encryption method,…

Naked DSL is a type of internet connection that does not require a phone line. Generally, people will need a landline for their internet connection before they can apply for Naked DSL. This type of internet connection does not have a phone line. Some providers offer bundled packages with landline phone service. If you are interested in getting this type of internet service, you must first check with your local ISP. Naked DSL is not suitable for everyone. If you are totally dependent on your phone line, then this option is not for you. However, it is suitable for people…

What is Gigabit WIFI router? Simply put, a gigabit wifi router is a high-speed wireless router that is able to deliver upload and download speeds that rival those of a standard wired internet access connection. A gigabit wifi router is simply a networking device that creates a virtual private network (VPN) that connects to the local area network (LAN). Nowadays, almost all modern computers will support gigabit technology - meaning that any PC which has a motherboard that supports USB 2.0 also supports a gigabit wifi router. There are two primary types of gigabit wifi routers available; these are wired…
