  2. Friending and following - Wikipedia

    en.wikipedia.org/wiki/Friending_and_following

    Following is a similar concept on other social network services, such as Twitter and Instagram, where a person (follower) chooses to add content from a person or page to their newsfeed. Unlike friending, following is not necessarily mutual, and a person can unfollow (stop following) or block another user at any time without affecting that user ...

  3. Parasocial interaction - Wikipedia

    en.wikipedia.org/wiki/Parasocial_interaction

    Twitter can provide a direct connection between followers and celebrities or influencers that gives access to everyday information. It is an entertaining way for most fans since Twitter enables them to be a part of life that they enjoy. [69] The more followers one has on Twitter, the greater perceived social influence one has. This is ...

  4. Current-mode logic - Wikipedia

    en.wikipedia.org/wiki/Current-mode_logic

    The difference of principal between CML and ECL as a link technology is the output impedance of the driver stage: the emitter follower of ECL has a low resistance of around 5 Ω whereas CML connects to the drains of the driving transistors, that have a high impedance, and so the impedance of the pull up/down network (typically 50 Ω resistive ...

  5. Lead and follow - Wikipedia

    en.wikipedia.org/wiki/Lead_and_follow

    Traditionally, the male dance partner is the leader and the female dance partner is the follower, though this is not always the case, such as in Schottische danced in the Madrid style where women lead and men follow (although this is not totally true: during the dance there is an exchange of roles, the leader becomes the follower and vice versa [3]).

  6. Buffer amplifier - Wikipedia

    en.wikipedia.org/wiki/Buffer_amplifier

    The difference between the non-inverting input voltage and the inverting input voltage is amplified by the op-amp. This connection forces the op-amp to adjust its output voltage to simply equal the input voltage (V out follows V in so the circuit is named op-amp voltage follower).

  7. Common collector - Wikipedia

    en.wikipedia.org/wiki/Common_collector

    Conversely, a voltage follower inserted between a small load resistance and a driving stage presents a large load to the driving stage—an advantage in coupling a voltage signal to a small load. This configuration is commonly used in the output stages of class-B and class-AB amplifiers.

  8. Precision Time Protocol - Wikipedia

    en.wikipedia.org/wiki/Precision_Time_Protocol

    An ordinary clock is a device with a single network connection that is either the source of or the destination for a synchronization reference. A source is called a leader, a.k.a. master, and a destination is called a follower, a.k.a. slave. A boundary clock has multiple network connections and synchronizes one network segment to another. A ...

  9. Social connection - Wikipedia

    en.wikipedia.org/wiki/Social_connection

    Social support is the help, advice, and comfort that we receive from those with whom we have stable, positive relationships. [11] Importantly, it appears to be the perception, or feeling, of being supported, rather than objective number of connections, that appears to buffer stress and affect our health and psychology most strongly.
