This is a server that all computers on the local network have to go through before accessing information on the Internet.  By using a proxy server, an organization can improve the network performance and filter what users connected to the network can access. While your Web browser might save recently viewed items on your computer, a proxy server stores in cache everything accessed from the network.  That means if Arun views a news story at cnn.com at 12:00 and Anitha views the same page at 12:03, she'll most likely get the page straight from the proxy server's cache. Though this means super-fast access to Web pages, it also means users might not be seeing the latest update of each Web page. The other main purpose a proxy server is to filter what is allowed into the network. While HTTP, FTP, and Secure protocols can all be filtered by a proxy server, HTTP is the most common.  The proxy server can limit what Web sites users on the network can access....

 Canvio Connect is  a portable USB 3.0 hard drive that enables personal cloud storage. The Canvio Connect comes preinstalled with software that turns the  p ortable drive into an online file server when it is plugged into a Windows or Mac computer.  As long as the Canvio Connect is connected to an Internet-enabled PC that is powered on, users will have complete access to files, photos, music and movies from any device. The Canvio Connect serves as a portable hard drive but can also be used to back up images and other files from mobile devices.  Toshiba has announced 10-GB of free cloud storage available to Canvio Connect users (via the Pogoplus service). Canvio Connect was announced  on April 30, 2013 by Toshiba's Digital Products Division (DPD), a division of Toshiba America Information Systems, Inc.

A torrent is a file sent via the BitTorrent protocol . It can be just about any type of file, such as a movie, song, game, or application.  During the transmission, the file is incomplete and therefore is referred to as a torrent. Torrent download that have been paused or stopped cannot be opened as regular files, since they do not contain all the necessary data. However, they can often be resumed using a BitTorrent client, as long as the file is available from another server. Torrents are different from regular downloads in that they are usually downloaded from more than one server at a time. The BitTorrent protocol uses multiple computers to transfer a single file, thereby reducing the bandwidth required by each server. When a torrent download is started, the BitTorrent system locates multiple computers with the file and downloads different parts of the file from each computer. Likewise, when sending a torrent, the server may send the file to mu...

A cron job is a script that runs on a web server to perform maintenance tasks on regularly scheduled intervals. web servers need to do weekly, daily, or even hourly, maintenance tasks. This helps them stay tartar free. Cron jobs can do all sort of things. They can backup files or databases, they can clean up data, they can send emails, they can transfer data from one place to another, they can update information from external sources. One of the most common cron jobs is a script that regularly logs onto the Internet and downloads all your email. The only thing that all cron jobs share is that they are scripts that are run automatically on a set schedule.

A technique for  mystifying  the true origin of packets on an IP network in order to preserve privacy and shield a user's online activities from monitoring by government, corporate or other entities.  Onion routing hides online activity by sending p ackets  through a distributed network  of randomly selected  proxy servers  before they are delivered to their final destination. Onion -routed packets are securely encrypted , with the packets unwrapped by a symmetric encryption  key at each server, peeling off the layers of the message a server at a time.  Onion routing was originally developed by the U.S. Navy, and the Navy has financed the development of a second-generation onion routing project known as Tor .

A phrase used to describe a half-smartphone and half-tablet mobile device (a phone/tablet hybrid).  A phablet is a small pocket-sized mobile device that is a bit larger than the size of an average smartphone, with a touch screen ranging in size from 5 inches (e.g. the Sony Xperia Z) to 6.1 inches (e.g. the Huawei Ascend Mate device).  While larger than a smartphone, the phablet is much smaller than most tablets and can be held and used in one hand. Phablets typically use 3G or 4G networks for cellular calls and are Wi-Fi-enabled devices.

A form of DoS attack known as a degradation -of-service attack, as opposed to a denial -of-service attack. Unlike a regular zombie that paralyzes a system by inundating it with a steady stream of attack traffic, the pulsing zombie attacks with irregular small bursts of attack traffic from multiple sources on a single target over an extended period of time. Pulsing zombie attacks are more difficult to detect and trace because since they are slow and gradual they do not immediately appear as malicious.
