  We investigated the main prompt and afterglow emission parameters of
gamma-ray bursts detected by the Burst Alert Telescope (BAT) and X-Ray
Telescope installed on the Swift satellite. Our aim was to look for differences
or connections between the different types of gamma-ray bursts, so we compared
the BAT fluences, 1-sec peak photon fluxes, photon indices, XRT early fluxes,
initial temporal decay and spectral indices. We found that there might be a
connection between the XRT initial decay index and XRT early flux/BAT photon
index. Using statistical tools we also determined that beside the duration and
hardness ratios, the means of the \gamma- and X-ray--fluences and the
\gamma-ray photon index differ significantly between the three types of bursts.
