LFO stands for Low-frequency oscillation. The name comes from the fact that it is an electronic signal with a low frequency, which oscillates to create a rhythmic pulse, or wobble. LFO's are common in synths and help vary their sound capabilities.
A number of popular effects are based around low frequency oscillation, namely chorus, vibrato, phasing, flanging and rotary speaker effects.

A MIDI keyboard is a piano-style keyboard used for sending MIDI data to a computer, or other MIDI devices. MIDI keyboards are a type of MIDI controller. You can think of a MIDI keyboard as a dummy keyboard. They don't produce any sounds themselves but rather, via MIDI data, control sounds in other devices, such as a synth on your computer or an external hardware synth.

MIDI (Musical Instrument Digital Interface) is a protocol that allows various electronic instruments and MIDI software to communicate with each other. The standard MIDI connector (5 pin DIN cable) is used to connect MIDI hardware, although some devices can also send MIDI data via USB cables to computers with MIDI software. MIDI software can also communicate using this data, eg. the MIDI sequencer in a program can send this information to a MIDI plugin.
