The utility model belongs to the field of electrotechnical products, and relates to a novel fire-resistant and flame-retardant computer cable. According to the fire-resistant and flame-retardant computer cable, a cable core consists of at least one pair of insulated wire cores which are twisted with each other, and the insulated wire core consists of a conductor and an insulating layer wrapped at the periphery of the conductor; an independent metal shielding layer is arranged outside each pair of insulated wire cores; a total metal shielding layer and low-smoke halogen-free and flame-retardant polyolefin outer protective layer are arranged outside the cable core; and a core fire-resistant heat-insulating layer which consists of a ceramic fiber heat-insulating belt and a ceramic silicon rubber fire-resistant layer is arranged between the cable core and the outer protective layer. Due to the adoption of the technical scheme, the computer cable has high performance of low smoke, non-halogen, flame retardance and
