The VOO glossary

3G/4G

These terms are used in the field of mobile telephony to define the power of the Internet signal received by your smartphone.
3G refers to the third generation of wireless Internet connection standards. They allow Internet surfing and music streaming at a high speed (384 kbit/sec).
4G, also called "LTE" (Long Term Evolution) refers to the fourth and latest generation of mobile signal. This is the fastest mobile internet connection to date. 4G is comparable to a home WiFi signal and allows the same use: access to multimedia applications and very high speed downloads (100 Mbit/sec).

4K

4K resolution, also called "UHD" (Ultra High Definition) refers to a digital image definition of 4000 pixels or more. Some brands are slowly beginning to market 4K TVs, but this image format is used primarily in the field of digital cinema. 

5GHz or 5G

Currently, modems use the frequency band "2.4GHz” for Wi-Fi. Evolutions in the Wi-Fi standard have given rise to the "5GHz" frequency band. This is available on the Netgear CG37000 and Technicolor modem. This Wi-Fi network is faster and more stable, but it has a smaller reach than the "2.4GHz" network because, at high frequency, waves subside much more quickly. Only the very latest devices support this Wi-Fi network. The 5GHz network is also only visible to compatible devices.

Amplifier

An amplifier is the name commonly given to a NIU (Network Interface Unit) or multiple supply point (MSP). This is a small box used to "split" the signal and power up to 4 TVs and 1 or 2 DATA signals (Internet and telephone).

Anti-virus

An anti-virus is a computer program whose function is to identify, neutralise and/or remove malicious software that might infect your computer (viruses, Trojans, etc.). The VOO Internet Security anti-virus software can also protect your children via a parental control system.

Bandwidth

We use the term bandwidth erroneously to describe the transfer rate of digital data. This rate is expressed in Megabit per second (Mbps). In other words, depending on your Internet use, the bandwidth will be more or less in demand. If you read a simple web page without videos and without images, the bandwidth will not be much in demand. On the other hand, if you download a film, the bandwidth will be in greater demand as more digital data will have to be transferred via the bandwidth. The broader the bandwidth, the higher the connection speed.

Bit/s

In the IT field, a bit is the basic unit for measuring information. The expression “bit per second (bit/s) refers to the data transfer speed in telecommunications. When you perform a speedtest, you obtain a download speed and upload speed expressed in Mbit/s. These are the speeds at which the data from the Internet are loaded onto your computer and at which data are sent from your computer to the Internet. The resulting measurement indicates the number of bits downloaded or uploaded per second. 

Bridge mode

A Netgear modem configured in bridge mode sees its router part deactivated, which means it is only a simple modem. It can then become a relay for an additional router. This will allow other devices (NAS, smart TV, game console, etc.) to connect to it within a local network. The modem will then send the connection codes to the "private" router configured in bridge mode, allowing devices to be connected to the Internet. When the VOO modem is in bridge mode, it no longer has a IPv6 firewall. This will deprive you of a IPv6 for obvious safety reasons.

CGN

Each modem/router connected to the Internet receives a unique IP address from the operator that allows it to identify itself on the network. There are two formats of IP addresses: IPv4 and IPv6. As the possible combinations of IPv4 are starting to be exhausted, operators are therefore encouraged to switch to IPv6, as the number of combinations is much greater. For the time being, sites and applications are not yet all adapted to IPv6. IPv4 thus remain commonplace. A CGN (carrier-grade NAT) is a technique that makes it possible to overcome this global shortage of IPv4. The technique consists of consolidating multiple customers under a single public IP.

CMTS

A CMTS (cable modem termination system) is a device that allows our customers’ modems to communicate with the Internet. This is an element of the network infrastructure that sends requests directly to your modem, and vice versa. A CMTS can supply 4000-15000 modems depending on its size.

Coupler

The coupler is the key link between the street and the customers (up to 4 per coupler). These terminals, often located on the outside of buildings and exterior columns, are used to deliver the signal to the client.

Data

Data refers to information in various forms This is the "data" that you consume when you use the mobile Internet (to consult mails, use applications, search for information, surf on social media, etc.). In other words, when we speak of "consumer data", it is your Internet usage on your mobile.

DHCP

DHCP (Dynamic Host Configuration Protocol) is a network protocol intended to automatically configure the settings of the different IP addresses assigned to computing devices. For example, your VOO router has an internal DHCP that will assign an IP address to every device connected by cable or Wi-Fi (computer, smartphone, etc.)

DLNA

DLNA (Digital Living Network Alliance) is an umbrella organisation for hundreds of electronic brands. This organisation has set up the DLNA system based on communication standards in order to transfer, play and control data (photos, videos, music, etc.) between different media devices (computers, smartphones, home theatre, etc.) of different brands.

Encryption

Encryption is a computer mechanism that secures your sensitive information circulating by Wi-Fi from ill-intentioned spies and potential attacks. The encryption process mathematically scrambles your data using a password. This encryption makes the personal information you store and send on the Internet unreadable and inviolable. Decryption is required for access.

Ethernet cable

An Ethernet cable, also called RJ45, is used to connect your computer (or any other device connected to a network) to your modem, router or server. The network is configured automatically. There are different Ethernet cables: the RJ45 and RJ11.

Firewall

A firewall is your computer’s protection system. The firewall allows you to protect yourself from hackers and all external intrusions by filtering the data exchanged with the network.

Frequency band

A frequency band refers to a set of wave frequencies with similar characteristics. In the field of broadcasting, a frequency band makes it possible to broadcast one analogue channel or up to ten digital channels. It is expressed in megahertz (MHz) and the set of frequency bands is known as the frequency plan.
In the field of wireless Internet, there are two possible frequency bands: the "2.4GHz" and "5GHz".

Full HD or HD Ready TV

Full HD or HD Ready TVs are capable of receiving HD signals (High Definition) carried by the HDMI output of the VOO decoders. High Definition offers several advantages including higher resolution and therefore better image quality.

Gb/Go

GB stands for "Gigabyte". Go stands for "Gigaotet" and is the French translation of "Gigabytes" (1 byte = 1 octet = 8 bits). This is the download volume included in your subscription package. For example, the tatoo subscription allows an unlimited download volume while toudoo allows a volume of 200 Go per month. It is also the transfer speed of your Netgear modem (or Technicolor modem)

Gui

Gui or modem interface is your modem control panel. It gives you access to various features, such as changing your wireless channel, viewing your IP address, activating your 5 GHz network, etc. To access theses features while connected to your modem, type "192.168.0.1" into your browser (in bridge mode, you will need to enter "192.168.100.1"). A web page appears. Enter "voo" (small letters) as user name and your password (capitals). You can find this password under your modem next to "Password (WPA)". Click "OK". 

H+

This term is used in the field of mobile telephony to define the power of the Internet signal received by your smartphone. The H + or DC (Dual-Cell High Speed Packet Access +) is the technology that preceded 4G. It makes it possible to receive and send a large volume of data very comfortably (42 Mbit/sec). 

HDMI cable

The HDMI (High Definition Multimedia Interface) is the only connector that actually carries the HD digital signals. It is used to connect a media feed reader (VOObox, VOOcorder or box .évasion) to a compatible HDTV. It carries a digital signal in High Definition for the image and in different formats for sound (Dolby Digital, DolbyTrue HD, etc.).

Homespot

The VOO Homespot or Wi-Free network is VOO’s Wi-Fi sharing system that makes it possible to surf free at high speeds outside your home, from your computer, tablet or smartphone. Each VOO connection becomes an Internet access point. A broad network is thus created with hundreds of thousands of access points.

IP address

All equipment (computer, modem, router, network printer, smartphone, etc.) connected to a computer network has an IP (Internet Protocol) address. This is a unique identification number at global level. A bit like a postal address, an IP address is therefore an address that makes it possible to identify a device on the computer network. 

IPv4/IPv6

A bit like a postal address, an IP address is therefore an address that makes it possible to identify a device connected to the computer network. V6 means "6th version." IPv6 is therefore the sixth version of the IP addresses. In fact, the IPv4 address is an identification address comprised of digits. As the possibilities for creating different IPv4 addresses is reaching saturation point, operators are encouraged to upgrade to version 6 of the IP addresses, or IPv6. The principle is the same as for IPv4 but the IPv6 address is comprised not only of numbers but also of letters. The number of different IPv6 addresses is therefore much larger and will therefore make it possible to keep step with the growth in the number of devices connected to the Internet. 

Levels of a modem

The levels of a modem are the information sent by the modem on your signal. The levels are comprised of several values: the Tx, Rx and Snr.
Tx means "Transmission" or "Transport", these are the values relating to the “return/uplink" signal strength. In other words, Tx represents the signal used when you make a call or when sending an email. This is the "upstream".
Rx means "Reception", these are the values relating to the "outward/downlink" signal strength. In other words, the Rx represents the signal used when you order a video on demand or when you download a web page. This is the downstream
The Snr is the "signal to noise". Its value must be high and stable. This is an indicator of the quality of your transmission signal, it is the "background noise" that interferes with your signal.

LTE

This term is used in the field of mobile telephony to define the power of the Internet signal received by your smartphone. "LTE" (Long Term Evolution), also called "4G" refers to the fourth and latest generation of mobile signal. This is the fastest mobile internet connection to date. 4G is comparable to a home Wi-Fi signal and enables the same use: access to multimedia applications and downloading at very high speed (100 Mbit/sec).

MB/Mo

MB stands for "Megabytes". Mo is short for "megaoctet" and is the French translation of "Megabytes". It is a unit of measurement of the amount of digital information. 1 Mb = 1 Megabyte = 1 million bytes. Bytes are frequently used to denote the capacity of computer memories or the speed of information transfer (e.g, a CD-ROM is 650 MB).

Micro SIM

A micro SIM card (Subscriber Identity Module) is the equivalent of a SIM card but smaller. The nano SIM, for its part, is even smaller. It is a chip used in mobile telephony. Once you have inserted this card into your mobile phone, it then allows you to store data (telephone numbers) and to communicate within the wireless network with which you have a subscription. 

MMS

A MMS is a message in the form of an image, photo, text or video. It can be sent to a mobile phone from another mobile phone.

Mobile internet

Mobile Internet allows you to access the Internet on a mobile support (e.g. smartphone, tablet) no matter where you are, as opposed to the fixed Internet accessible from desktop computers. When you connect to the 4G network, you use the mobile Internet. The boom in smartphones, tablets and dedicated mobile applications have contributed to the democratization of the mobile Internet.

Modem interface

The modem interface (also called Gui) is your modem’s control panel. It gives you access to various features, such as changing your wireless channel, viewing your IP address, activating your 5 GHz network, etc. To access theses features while connected to your modem, type "192.168.0.1" into your browser (in bridge mode, you will need to enter "192.168.100.1"). A web page appears. Enter "voo" (small letters) as user name and your password (capitals). You can find this password under your modem next to "Password (WPA)". Click "OK". 

NAS

NAS (Network Attached Storage) is a box that contains one or more hard drives and has several features. It can store data (music, photos, videos, films, etc.). It also makes it possible to share data across one or more networks via a wired or Wi-Fi connection. The data are therefore centralised in one location (on the NAS) and are then accessible from different computers. Finally, it makes it possible to secure data.

NAT

The NAT (Network Address Translation) is a method of collecting a set of IP addresses in a private network in a single global IP address. NAT makes it possible to cut down on the number of unique IP addresses used and thus counter the shortage of IPv4. Some functions (such as remote cameras or peer to peer) are however not available in NAT.

Node

VOO uses HFC (Hybrid Fiber Coax) technology. This hybrid Internet network consisting of optical fibre and coaxial cable, can broaden bandwidth and thus the capacity of our network. In an HFC network, a node or "optical connection node" is an entity containing all the lines of subscribers from the same district or town. 

Operating system

An operating system (or OS) is the intermediary between a computer and its software and peripherals. The properties of a computer (main memory, RAM, CPU management, external communication capacity, etc.) are defined relative to the operating system. This is what allows a computer to function. There are different operating systems on the market, such as Windows, Mac OS, Linux and Android.

Optical fibre

An optical fibre is a very thin glass or plastic fibre that has light conducting properties and that is used for data transmission. It offers an information speed that is significantly higher than coaxial cables and supports a "broadband" network through which television, telephone, videoconferencing or computer data can pass. Optical fibre enables communication over very long distances and at very high speeds.

Phishing

Phishing is a technique used by fraudsters to steal personal information. The technique sets out to make the victim believe it is dealing with a trusted third party (bank, administration, etc.) in order to obtain personal and confidential information: password, credit card number, date of birth, etc. It is a form of computer attack that can be done by email, by falsified websites, etc.

POP3

POP3 (Post Office Protocol) makes it possible to receive email. This is the protocol that allows you to connect to your mailbox, read, sort, or delete messages. POP3 is the version currently used worldwide. This is the inverse process to the SMTP (cf. SMTP).

RJ11 telephone cable

This is the mostly commonly used cable for fixed telephony. The RJ11 cable connects the TEL 1 port (or TEL 2, only if you connect a second landline/second number) of the modem to your landline phone. Customers are strongly advised not to connect RJ11 splitters and extenders.

RJ45 Ethernet cable

The RJ45 cable (Registered Jack) makes it possible to carry Internet information. It is used to connect network cards (computer, wired PLC, connected printer, etc.) to the VOO modem. We recommend against using an RJ45 cable of over 10 meters that would generate information loss or significantly slow down Internet surfing.

Roaming

The word Roaming is used when you use your mobile when you are outside your mobile network. This is known as “national roaming”. By extension, we usually talk of "international roaming" when using our mobile phone abroad to call, send a text message, surf the Internet, or to receive calls or text messages. In fact, when you go abroad, you leave the area covered by VOO. You are then automatically connected to the network of a foreign network operator, which may incur additional charges.

SCART cable

The SCART cable makes it possible to directly connect a TV to an audio-video device. It only carries a "false" digital image and stereo sound. This cable does not support HD information, so it is becoming less and less common.

SMTP/server

A SMTP (Simple Mail Transfer Protocol) makes it possible to send electronic mail (email). It is the intermediary between your email and the recipient of your email, the element that will "translate" and send your mail in text format to the server of the host of the mailbox (Outlook, Gmail, Thunderbird, etc. ) This is one of the most common and widely used services on the internet. Its inverse process is the POP.

Spyware

Spyware is a spy program whose function is obtain information about your browsing habits without your knowledge. Spyware is usually installed on your computer as a virus or following the installation of a downloaded program. It runs in the background and is not visible. The collected data are often sold on to advertisers or used to send you targeted advertising (popup, banner, etc.).

Voicemail

Voicemail is the messaging service on which you leave a voice message to your friends when they do not answer the phone. By extension, it is also the service that allows you to record a voice message that is automatically played when someone tries to contact you: "Welcome to the Mr X’s voicemail, I can’t answer your call right now ..."

WAP

A WAP (Wireless Access Protocol) is a communication protocol. This technology allows a wireless device (such as a smartphone) to access the Internet. The WAP is unique to each mobile operator.

Web browser

A web browser is computer software that allows the user to consult the World Wide Web (WWW) or, in other words, to display and surf between different web pages. There are several browsers on the market, such as Internet Explorer, Mozilla Firefox, Safari or Google Chrome.

WEP

The WEP (Wired Equivalent Privacy) is an encryption that makes it possible to secure wireless networks such as Wi-Fi. WEP was replaced by WPA in 2003 and WPA 2 in 2004. These offer a more complex security system that will protect you more effectively against the most experienced attackers.

Wi-Fi

Wi-Fi (Wireless Fidelity) is the technology that allows you to take advantage of a wireless internet connection. With Wi-Fi, your electronic devices (computer, printer, decoder, smartphone, etc.) are interconnected on the same network. It allows the transmission of data by radio waves.

Wi-Free

The VOO Homespot or Wi-Free network is VOO’s Wi-Fi sharing system that makes it possible to surf free at high speeds outside your home, from your computer, tablet or smartphone. Each VOO connection becomes an Internet access point. A broad network is thus created with hundreds of thousands of access points.

WPA/WPA 2

The WPA key and its successor, the WPA2 (Wi-Fi Protected Access) are encryption techniques used to secure wireless networks such as Wi-Fi. They allow better security than the WEP. Moreover, the WPA 2 requires a more elaborate security key and allows you to encrypt your most confidential documents. By default, your device will use WEP, you have to manually enable WPA or WPA2.
