A Shield is an energy barrier.


Shields typically differ from Force fields by encompassing an object rather than forming a single barrier, but the terms are often interchanged. (SG1: "The First Commandment", "Evolution, Part 2") Shields will protect from projectile and energy weapons but can only withstand a certain amount before they can be overcome. (SG1: "The Nox", "Bounty", "Unending") Shields cycle through various frequencies to match incoming energy-based attacks and when close they are able to withstand more energy. (SGU: "Gauntlet")


The Ancients possessed some of the most advanced shields, capable of resisting massive amounts of energy for long periods, often due to the power sources the shields used, such as Zero Point Modules. (SGA: "Rising", "Echoes", "The Siege, Part 3") The shields on the Taonas outpost had lava flow over it for years but maintained long enough for the lava to harden. (SG1: "Lost City, Part 2") The shield on Atlantis was capable of running for over 10,000 years with the constant pressure of the ocean on it, attenuating to a thin shell over time but mostly remaining intact. (SGA: "Rising") Atlantis' shield was also capable of resisting a direct hit from a Nuclear bomb as well as a Coronal mass ejection. (SGA: "The Siege, Part 3", "Echoes")


The Asgard shields were more advanced than the Goa'uld, often being unaffected by Goa'uld weapons until they were upgraded. (SG1: "Revelations") Their shields were able to withstand fire for Ori Warships longer than most others. (SG1: "Camelot")


Goa'uld shields were powerful enough to withstand Nuclear bombs and most energy weapons, except those used by the Asgard and Tollan. (SG1: "The Serpent's Lair", "Revelations", "Pretense") Their smaller shields were designed to protect mostly from energy, such as Staff weapon blasts, but also from faster moving projectiles, meaning that slowing projectiles like darts would pass right through them. (SG1: "The Nox", "Secrets") They had shields that operated like solid walls. (SG1: "Into the Fire", "Upgrades")


The Ori shields were able to resist fire from almost all types of energy weapons but were bypassed eventually by Asgard Plasma beam weapons. (SG1: "Camelot", "Unending") The shields fluctuated when the Ori Warships fired their beam weapons. (SG1: "Camelot")


The Tau'ri based their first shields off of Goa'uld designs. (SG1: "Prometheus") The Asgard later provided them with shields of their own design. (SG1: "Disclosure") The Tau'ri obtained full designs of Asgard shields when the Asgard gave them all their technology. (SG1: "Unending")
