The Series 800 (Model 101) consist of various important parts:
The T-800 contains a Neural Net Processor CPU, or "learning computer", contained within the endoskeleton's skull and protected by inertial shock dampers. The CPU, developed by Cyberdyne Systems, is one of the most powerful microprocessors ever built. As part of its vast internal databases, the T-800 contains detailed files on human anatomy and physiology so as to make it a more efficient killer. The CPU could also be updated with multiple database files related to advanced infiltration techniques, basic training for soldiers, emergency medical training, sniper training, an extensive tactical database, and detailed files from other terminators making each unit a combat veteran.
The metal endoskeleton of the T-800 is a microprocessor controlled fully armored hyper-alloy combat chassis and is constructed with frictionless bearings in its joints, and a servo-actuated control system. Its limbs are controlled by axial drive motors and clavicular trailing links, allowing the T-800s to maneuver faster than the Series 600 Terminators, as bursts of speed of up to 22 mph no longer threatened the joint assemblies. The T-800 was also 20% lighter and 40% stronger than the T-600. The armored frame is capable of withstanding most small arms fire and is able to survive being set on fire and being covered in molten steel with only minimal damage and no degradation of capabilities. There are weak spots anyway; Kyle Reese was able to blow the first Terminator in half with a pipe bomb by jamming it in between its joints. However, the upper half torso was still functional albeit with severed left arm. Sharp-edged objects such as metal pipes or shrapnel could penetrate the endoskeleton armor plate if propelled with sufficient force. Energy weapons like those mounted on the T-X could penetrate the armor and momentarily disable the T-800. Enough force could permanently dislocate limbs and disrupt the internal frame.
This is referred as the mold around the endoskeleton. Living tissue grown specially for the T-800's consists of flesh, skin, hair and blood, the synthetic flesh takes approximately 40 days to adequately be attached to an endoskeleton and is capable of limited regeneration over time. As this tissue is living it is warm to the touch and hence T-800's will not show up on thermal scanners as being any different from a real human. The biological components are only grafted onto T-800's which are to be used to infiltrate Resistance bases; T-800's which are deployed straight onto the battlefield usually do not possess biological components. As part of our scientific progression, mankind has unravelled the human genome and we were able to identify the genes which control cell life-span and degradation. Using this information, stored within its vast databases, Skynet has been able to eliminate these unwanted genes from cells prior to industrially growing biological components for the T-800's. This means that the skin and muscles of the T-800's, unlike the human equivalents, do not wear down, degrade or necrotize over relatively short periods of time. It also means that the T-800's biological components will not rot over long periods of time, and do not require a flow of nutrients or anti-bodies. However, if a T-800 is left on the battlefield for too great a period, its biological components will begin to rot, and its cover will be blown. Though it does not need nutrient or blood flow, the T-800 has a circulatory system which is controlled by a tiny pneumatic pump which maintains a constant pressure. This allows the T-800 to bleed convincingly when wounded. However, the living tissue of the T-800's is still prone to necrotizing after a period. Therefore, when not in active service, flesh covered T-800's are stored in special racks in a cryogenic vault to preserve the flesh from deteriorating.
