To copy data from a main source to another device. The term is often used to describe the process of copying a file from an online service or bulletin board service (BBS) to one's own computer. Downloading can also refer to copying a file from a network file server to a computer on the network. Source:

DSL (Digital Subscriber Line)

Refers collectively to all types of digital subscriber lines, the two main categories being ADSL and SDSL. DSL technologies use sophisticated modulation schemes to pack data onto copper wires. They are sometimes referred to as last-mile technologies because they are used only for connections from a telephone switching station to a home or office, not between switching stations. Source:

DSLAM (Digital Subscriber Line Access Multiplier)

A mechanism at a phone company's central location that links many customer DSL connections to a single high-speed ATM line. Source:

Gb (Gigabit)

Gigabit (Gb) is a data measurement unit applied to digital data transfer rates (DTR) and download speeds. One Gb equals one billion (1,000,000,000 or 109) bits. Source:

ISDL (ISDN Digital Subscriber Line)

A method of providing DSL technology over existing ISDN lines. Even though the transfer rates for IDSL are about the same as ISDN (144kbps v. 128kbps), and IDSL circuits typically only carry data (not voice), the major benefits of switching to IDSL from ISDN are always-on connections, thus eliminating call setup delays; flat rate billing, instead of per minute fees; and transmission of data over the data network, rather than the PSTN. Source:

ISDN (Integrated Services Digital Network)

An international communications standard for sending voice, video, and data over digital telephone lines or normal telephone wires. ISDN supports data transfer rates of 64 Kbps (64,000 bits per second). Source:

IP Telephony (Internet Protocol Telephony)

An IP telephone system uses packet-switched Voice over IP (VoIP), or internet telephony, to transmit telephone calls over the internet instead of the circuit-switched telephony used by the traditional Public Switched Telephone Network (PSTN). Also known as VoIP phone systems. Source: 

ISP (Internet Service Provider)

Short for Internet Service Provider, it refers to a company that provides Internet services, including personal and business access to the Internet. Source:

LAN (Local Area Network)

A local-area network (LAN) is a computer network that spans a relatively small area. Most often, a LAN is confined to a single room, building or group of buildings, however, one LAN can be connected to other LANs over any distance via telephone lines and radio waves. A system of LANs connected in this way is called a wide-area network (WAN). Source:

Mb (Megabit)

Megabit (Mb) is a data measurement unit applied to digital computer or media storage. One Mb equals one million (1,000,000 or 106) bits or 1,000 kilobits (Kb). Source:

Mbps (Megabits Per Second)

Megabits Per Second (Mbps) is a measurement unit applied to digital data transfer rates (DTR) related to any type of media or computer. One Mb equals one million (1,000,000 or 106) bits or 1,000 kilobits (Kb). One Mbps is capable of downloading one million bits of data per second. Source:

Mobile Internet Device (MID)

A Mobile Internet Device (MID) is a small multimedia-enabled mobile device that provides wireless Internet access. MIDs facilitate real-time and two-way communication by filling the multimedia gap between mobile phones and tablets. Source:

Naked DSL

A naked DSL (a.k.a. standalone or dry loop DSL) is a digital subscriber line (DSL) without a PSTN (analogue telephony) service — or the associated dial tone. In other words, only a standalone DSL Internet service is provided on the local loop. Naked DSL is the same as standard DSL, except that there is no voice service. Telephone service is not required for DSL to operate correctly. Source:

Ping is a network diagnostic tool used primarily to test the connectivity between two nodes or devices. To ping a destination node, an Internet Control Message Protocol (ICMP) echo request packet is sent to that node. If a connection is available, the destination node responds with an echo reply. Ping calculates the round-trip time of the data packet's route from its source to the destination and back, and determines whether any packets were lost during the trip. Source:

PSTN (Public Switched Telephone Network)

Refers to the international telephone system based on copper wires carrying analog voice data. This is in contrast to newer telephone networks base on digital technologies, such as ISDN and FDDI. Telephone service carried by the PSTN is often called plain old telephone service (POTS).


A router is a device that analyses the contents of data packets transmitted within a network or to another network. Routers determine whether the source and destination are on the same network or whether data must be transferred from one network type to another, which requires encapsulating the data packet with routing protocol header information for the new network type.

Satellite Broadband

Satellite broadband is network connectivity provided through low-earth-orbit (LEO) or geostationary satellites, with the latter providing much faster data rates. Satellite broadband enables Internet access via satellite in two steps:

  1. A personal computer broadcasts requests via satellite modem to a satellite dish placed on top of a home or business.
  2. The dish sends and receives signals from the orbiting satellite. If the dish is able to get a clear view of the southern sky, a user can receive satellite Internet access.

Satellite broadband is also known as satellite Internet access. Source:

SHDSL (Single-pair high-speed digital subscriber line)

SHDSL is a form of symmetric digital subscriber line (SDSL), a data communications technology for equal transmit and receive (i.e. symmetric) data rate over copper telephone lines, faster than a conventional voiceband modem can.  Source


Data streaming is the process of transferring a stream of data from one place to another, to a sender and recipient or through some network trajectory. Data streaming is applied in multiple ways with various protocols and tools that help provide security, efficient delivery and other data results. 


Uploading refers to the process of copying files from a smaller peripheral device to a large central system. Source:

VoIP (Voice over Internet Protocol)

Voice over Internet Protocol, or VoIP, telephone products connect to VoIP, or Internet telephony, systems, which use packet-switched telephony to transmit calls over the Internet as opposed to the circuit-switched telephony used by the traditional Public Switched Telephone Network (PSTN).

VPN (Virtual Private Network)

A network that is constructed by using public wires — usually the Internet — to connect to a private network, such as a company's internal network. 

WAN (Wide Area Network)

A computer network that spans a relatively large geographical area. Typically, a WAN consists of two or more local-area networks (LANs).Computers connected to a wide-area network are often connected through public networks, such as the telephone system. They can also be connected through leased lines or satellites. The largest WAN in existence is the Internet.

Wireless Broadband Ethernet

Wireless internet enables wireless connectivity via radio waves rather than wires on a person's home computer, laptop, smartphone or similar mobile device. Source:
