  • An Internet Service Provider is a company that lets you access the Internet from your home or office by using a DSL modem, a cable modem or any other device (including sattelite links, etc.).

    They are a gateway between the connection that goes into your home/office and the rest of the Internet.

  • A modulator-demodulator is a device used to transmit digital data over an analog channel. It modulates/demodulates a carrier signal in order to encode digital information onto it.

    A modem is typically used to transmit computer data over POTS phone lines.

  • An image type that simulates grayscale by varying the density of dots in a given area.

    Highly colored areas consist of a large density of dots, while lighter areas consist of a lower density of dots.

  • Wired Equivalent Privacy (WEP) is a security protocol specified in the IEEE 802.11 standard to provide the same level of security as the one of a wired LAN.

    WEP provides security by encrypting data sent wirelessly so that it is protected as it is transmitted from one end point to another.

    WEP is not regarded as very secure in the industry.

  • The CTA is the primary usier interface element (button, link, form...) that asks the user to take the action the website would like its visitors to take. This results in a "Conversion".

    Examples: "Buy now" button, "Sign up", "Download now", "Subscribe here"...

  • WPA-PSK (WPA Pre-Shared Key) is special mode of WPA for small business or home users.

    A shared key, or password, is configured in the wireless access point (WAP) and any wireless laptop or desktop devices. WPA-PSK generates a unique key for each session between a wireless client and the associated WAP for more advanced security.

  • Frame-based computer networking technology used in local area networks (LANs). Ethernet defines wiring and signaling for the physical layer, and frame formats and protocols for the media access control (MAC)/data link layer of the OSI model. Ethernet is mostly standardized as IEEE 802.3.

    It has become the most widespread LAN technology since the 1990s.
