This might not be the best answer but, preparing a buffer solution allows one to keep the pH value the same when small amounts of acids or bases are added. Buffer solutions resist change in pH. Source: My Chemistry teacher's PowerPoint
TE buffer contains EDTA, which is a strong chelating agent. It chelates the Mg2+ ions present in the solution. Since endonucleases use Mg2+ for their activity, degradation is slowed or checked using this buffer. This buffer is also maintained at a pH of 8.0 for the same reason. At this pH, the endonucleases show least activity. All in all, the DNA or RNA sample that we have is safe from getting degraded.
The main difference is in composition. In TE common Tris buffer is bring down to pH 8 with HCl and EDTA is involved but in TAE instead of Tris HCl in TE Tris-acetate buffer is used.
The conductivity of the tris buffer 1 is found to be 4.0mmho/cm. The conductivity is achieved at a temperature of 27 degrees.

tris, EDTA (TE solution) and NaCl, TNE buffer is a buffer solution used in molecular biology, especially for DNA and RNA
"Tris" is a chemical compound used as a buffer. The full name is tris(hydroxymethyl)aminomethane. Tris has the ability to absorb counter ions (+H and -OH) so as to help keep the solution that they are in at a stable pH level. When the pH of Tris is set using HCl (hydrochloric acid) the buffer is called Tris HCl.
Tris is most commonly used as a biochemical buffer. It is also known by the names TRIS, THAM, Trisamine, Tromethamine, Tromethane, Trizma and Trisaminol.
