Peer-to-peer (P2P) file sharing is a system of sharing files directly between network users, without the assistance or interference of a central server. Files reside on computers of users all over the world and are shared bit by bit between those users directly. The decentralized nature of peer-to-peer file sharing removes the need for a central server, and removes the possibility of centralized control. Because peer-to-peer file sharing networks do not require a central server, they are more scalable and more redundant than centralized file sharing schemes. Peer-to-peer file sharing Read More

Group Policy Objects (GPOs) containing Group Policy settings can be linked to sites, domains, and organizational units (OUs), so that they are applied to user objects or computer objects located in the particular site, domain, or OU in Active Directory. Because of numerous Group Policy settings that exist, and the flexibility of group policies, Group Policy management can be an intricate task. GPOs can be linked, filtered, inherited and blocked, and are cumulative when they are applied to the local computer, site, domain or OU. Resultant Set of Policy (RSoP) Read More

ASIO (Audio Stream Input/Output) is a sound card driver protocol designed for professionals with the goal of reducing latency (a delay between input and output audio signals). Steinberg, a company very well known for its premium music production software such as Cubase, created ASIO. Steinberg also invented the VST plugin standard used in almost all digital audio workstations today. In a nutshell, ASIO bypasses standard Windows intermediaries and allows more direct access to the sound hardware. Reducing the number of “hoops” through which the signal has to pass results in Read More

A High Definition Multimedia Interface (HDMI) signal is sent through an HDMI cable. It is designed to be used with extra high resolution video feeds coming from DVD, Bluray, etc., which are then routed to a compatible viewing screen such as a television or computer monitor. HDMI cables are capable of different speeds based on the materials used to create them. HDMI uncompressed digital signals can be carried through a cable with resolutions of up to 1080 pixels in vertical size (which is commonly set to 1920 pixels horizontally), although Read More

EAP, LEAP, PEAP, and TTLS are competing protocols for securely transporting authentication data. EAP EAP (Extensible Authentication Protocol), defined in RFC 2284 — PPP Extensible Authentication Protocol (EAP), is the original 802.11 standard. LEAP LEAP (Lightweight Extensible Authentication Protocol) is a proprietary protocol which was developed by Cisco. Cisco is phasing out LEAP in favor of PEAP. EAP-TLS EAP-TLS (Extensible Authentication Protocol – Transport Layer Security) was created by Microsoft and accepted by the IETF as RFC 2716: PPP EAP TLS Authentication Protocol.. PEAP PEAP (Protected Extensible Authentication Protocol) is Read More

Computers provide excellent resources and capabilities for millions of users around the world that are not presented in any other technology. Computers require extensive maintenance, however, and begin to exhibit many different problems when not taken care of properly. Computers must be cleaned virtually and physically in order to keep the computer at an optimal performance. By using the following programs and performing the tasks written out below, the user will be able to increase the overall processing speed of their computer, increase virtual memory, and avoid expensive computer repair Read More

An outdoor TV antenna is one that receives radio signals from satellites or Earth-based radio transmitters. Outdoor TV antennas often receive a better signal than indoor TV antennas because they are in direct sight of a transmitter without interference from walls, electrical wiring, or any electronic devices. Outdoor TV antennas range dramatically in design and usually receive VHF (Very High Frequencies) or UHF (Ultra High Frequencies). How Outdoor TV Antennas Work An outdoor TV antenna, like every other type of antenna, is a transducer that converts electromagnetic waves into electricity Read More

Desktop themes are an extremely easy and usually a fun way to customize the look and feel of your computer's desktop. Desktop themes are usually referred to as a preset package or complete package of graphical tools and interfaces that one experiences visually when using their computer desktop. There is also another term used called a "skin". While a skin does customize the look and feel of a desktop object, a skin is usually for one specific object such as a media player, a desktop theme on the other hand Read More

PATA is an abbreviation for Parallel Advanced Technology Attachment. It is a regular interface that is used within PCs to connect all kinds of storage devices like hard disks, CD or DVD drives and solid state disks to the motherboard. The PATA interface connector is made up of thirty four pins and is connected to a ribbon-like flat cable nearly two inches broad. It does not support hot swapping. PATA was earlier known as just Advanced Technology Attachment. But with the introduction of SATA (Serial Advanced Technology Attachment) a few Read More
