Modern SIM cards allow applications to be loaded when the SIM is in use by the subscriber. These applications communicate with the handset or a server using SIM application toolkit, which was initially specified by 3GPP in TS 11.14 (there is an identical ETSI specification with different numbering).
(Redirected from Voltage follower) A buffer amplifier (sometimes simply called a buffer) is one that provides electrical impedance transformation from one circuit to another. Two main types of buffer exist: the voltage buffer and the current buffer.
A voltage regulator module (VRM) is an installable module that senses a computer's microprocessor voltage requirements and ensures that the correct voltage is maintained.oth use 2.8 volts. However, the Pentium Pro and the Pentium with MMX have different voltage requirements for core (2.8 volts) and I/O (3.3 volts). Adding a VRM allows it to regulate the voltage for I/O while the original regulator built into the motherboard continues to regulate core voltage.
