VANET:
Vehicular Ad Hoc Network (VANET) is a type of MANET that allows vehicles to communicate with roadside equipment. While the vehicles may not have a direct internet connection, the wireless roadside equipment may be connected to the internet, allowing data from the vehicles to be sent over the internet. The vehicle data may be used to measure traffic conditions or keep track of trucking fleets.
VDU:
Visual Display Unit (VDU) is another term for monitor or screen, but may also refer to a projector or other type of display. VDUs may be peripheral devices or may be integrated into a computer system. While early VDUs were mainly CRT displays, today most monitors are flat panel displays that use LCD or LED technology.

Viasat Data Allowance Policy:
All Viasat Internet plans come with the fastest speeds available in your local area. The main difference between each plan is how data usage is managed. Viasat’s Liberty plans have a fixed amount of data you can use monthly. With Viasat’s NEW unlimited data plans, there are no limits to how much data you can use during your monthly billing cycle. However, during high traffic hours when the network is busy, we may prioritize your unlimited plan data behind other Viasat customers after you exceed 150 GB of data usage. This may result in occasional slower speeds.

Video Data Extender:
All older Exede Essential 10, Evolution, Liberty, Freedom, Basic 12 and the Exede Classic plans include the Video Data Extender. This is a feature that streams video at DVD quality (optimized for 480p), which allows you to get more out of your monthly data allowance. This feature is turned on by default. Not all video sources are identifiable and available to benefit from the Video Data Extender. You can turn the Video Data Extender off or on at any time by visiting your Viasat account.
Video Screen Resolution:
This term describes how many pixels a monitor or TV screen can display. The number of horizontal and vertical pixels on a display screen. The higher the resolution, the more that can be displayed on the screen. The more pixels, the clearer the image. Pixelation is defined by the number of horizontal lines a video has from top to bottom. For example, a 360p video is made up of 360 lines stacked one on top of another, with each line being 480 pixels wide. In other words, a 360p has a video screen resolution of 480 × 360 pixels.
A small monitor may have a video screen resolution or 640 x 480, which means there are 640 pixels horizontally across the screen and 480 pixels vertically. Some other common monitor resolutions are 800 x 600, 1024 x 768, and 1280 x 1024.
Visasat offers video screen resolution plans available in 360p, 480p, 720p or 1080p pixelation. With 360p being standard size, 480p is considered DVD quality, 720p is HD video and 1060p is full HD.
Video Streaming:
An online technology that allows video to be viewed on a computer, laptop, smart device or TV through the internet as a continuous media stream, instead of saving it to the hard drive. Sites like Amazon Prime Video, Hulu & Netflix use video streaming technology. When streaming media online, a user does not have to wait to download and save a video file before playing it. Because the media is sent in a continuous stream of data, users can pause, rewind or fast-forward, just as they could with a downloaded file, unless the content is being broadcasted live in real-time.
Media is usually streamed from prerecorded files but can also be distributed as part of a live broadcast feed. In a live broadcast, the video signal is converted into a compressed digital signal and transmitted from a web server as multicast, sending a single file to multiple users at once. Streaming video is transmitted by a server application and received and displayed in real-time by a client application called a media player. A media player can be either an integral part of a browser, a plug-in attachment, a separate program or a dedicated device, such as a smartphone or TV. Frequently, video files come with embedded players. YouTube videos, for example, run in embedded Flash players. While video streaming media technologies have improved significantly, the quality of streamed content is still dependent upon the user’s connection speed.
Virtual Private Network (VPN):
A VPN allows you to use public connections with the security of a private network. A VPN is often used by at-home remote workers (telecommuters) who need a secure connection to their work servers. Some VPNs may be slow with Viasat internet, while others may work just fine. Additionally, while many VPN systems work, some VPNs may not work at all. SSL-based VPN systems like Cisco are our most commonly successful VPN customers. However, for use of a IPsec VPN you will need to upgrade to a Viasat Business plan. The average latency per customer feedback is 650ms and download speeds are up to 100 Mbps / Upload 3 Mbps. You should check with your company’s tech support or IT department to confirm whether your system uses a SSL-based or IPsec-based VPN and confirm that Viasat’s service will meet your requirements.
Virus:
Computer viruses are small programs or scripts that can negatively affect the health of your computer system. These malicious programs can create hidden files, move files, erase files, corrupt files, consume your computer’s memory and cause your computer not to function correctly. Some viruses can duplicate themselves, attach themselves to programs and travel across networks. Opening an infected email attachment is the most common way to get a virus.
The best offense is a good defense and it is better to prevent an attack than to try and cure it. There are many antivirus programs available that scan incoming files for viruses before they can cause damage to your computer. Some of these programs include McAfee AntiVirus, Norton AntiVirus and Webroot AntiVirus. It is recommended that you install one of these programs on your computer to prevent a virus or malware attack. It is also important to update your virus definitions file at least once a month so that your anti-virus program can check for all the latest viruses and online threats.
Visual Display Unit (VDU):
Another term for monitor or screen, but may also refer to a projector or other type of display. VDUs may be peripheral devices or may be integrated into a computer system. While early VDUs were mainly CRT displays, today most monitors are flat panel displays that use LCD or LED technology.
Voice Over Internet Protocol (VoIP):
Voice over Internet Protocol (VoIP) is a technology that turns sounds (your voice) into data so it can be sent over the internet. The data is sent digitally, using Internet Protocol (IP) instead of analog telephone lines, allowing people to talk to one another long-distance without having to pay long distance phone charges. This is the technology behind Viasat Voice home phone service, which provides high-quality local and long distance phone service.
Viasat Voice ;is optimized specifically for your Viasat satellite network and includes unlimited local & long-distance calls in both the U.S. and Canada. Plus when you bundle Viasat Voice with your Viasat internet services, you will save off your monthly Viasat bill. See the Viasat VoIP Voice page for more information & pricing.
NOTE: If you already have VoIP service with another provider, typically other VoIP services work fine with Viasat internet, but you will enjoy better quality with Viasat Voice. Plus, with Viasat Voice, your calls do not count toward your monthly data allowance.

However, for use of a IPsec VPN you will need to upgrade to a Viasat Business plan. The average latency per customer feedback is 630ms (millisecond), with download speeds are up to 100 Mbps. You should check with your company’s tech support or IT department to confirm whether your system uses a SSL-based or IPsec-based VPN and confirm that Viasat’s service will meet your requirements.
