UV-visible absorption spectroscopy probes electronic transitions due to electronic excited states, where as absorption of IR radiation excites molecular vibrations and no electronic excited states. However, UV-visible radiation can also excite the molecular vibrations as well, and so what is observed is the superposition of the electronic absorption in addition to the vibrational absorption spectra. IR spectra are broadened by molecular rotations, which are caused by the absorption of lower energy microwave radiation (and rotational spectra can be extremely sharp). If the species you are probing are atoms only, than they do not have any vibrations (because there are no bonds) and so the UV-visible spectra of atoms is very sharp.
A broad-spectrum antibiotic acts against many different kinds of disease-causing bacteria, including both gram-positive and gram-negative bacteria. A narrow-spectrum antibiotic acts only against specific families of bacteria.
In the field of spectroscopy absorption a peak means the wavelength of radiation where a sample absorbs. Different molecules absorb radiation of different wavelengths. An absorption spectrum will show a number of absorption bands, each one corresponding to structural groups within the molecule. Each band is represented by peak if you plot absorbance vs wavelength. By knowing which structural groups correspond to which peaks, you can often identify a compound by it's spectrum. For many molecules, the spectrum has been characterized, and you can use the spectrum to determine the purity, concentration, or other properties of the molecule by looking at the position and intensity of the peaks in the absorption spectrum.

There are a lot more. Each element has several possible absorption lines. In fact the element iron has several hundred lines.
They are related by they are both spectrums that give the color(s) that the element is. The Emission Spectrum shows what color(s) it gives off, and the Absortion shows what color it absorbs and doesn't show. They also fit together and make a continuous spectrum.
"Emission Spectrum" can mean a number of things... Many objects emit light and they all have an emission spectrum, that is a set of wavelengths of light that they give out. The emission spectrum for an L.E.D. bulb for instance is pretty narrow, just one visible colour. The emission spectrum of a star is very wide, encompassing non-visible light as well. It is probably these stellar emission spectra you are referring to, so I'll go on from that assumption. The fusion processes within a star (at most levels from core to surface, but mostly in the core) create most of a spectrum, but some of this light is absorbed by the outermost layers. That is why we see gaps, and molecules of certain types absorb certain parts of the spectrum, so we use the spectrum to determine composition. We also see spectra from diffuse bodies like nebulae. These are, broadly, of 2 types, emission and absorption. Absorption spectra occur when we observe a known star through the cloud, and extra lines missing beyond what we expect of the star will be emblematic of the constituents of the cloud. Emission spectra from clouds can also occur, that is when the light falling on them is not aligned with us, what we see is several narrow bands of light, which has been absorbed and re-emitted by the cloud.

Are you talking about silly bands? Silly bands are shaped rubber bands that many kids wear around their wrists. Hope that helps.
