The computer is highly advanced in its ability to communicate with others, often choosing to speak in a more casual tone. Although the computer often gives its master advice, Zim usually ignores it, even shouting out "I don't pay you to contradict me!" in Walk for Your Lives, to which the Computer responded with "You don't... pay me at all." It often becomes very exasperated with Zim, occasionally ignoring him, being sarcastic or blatantly refusing to do things for him. On occasion it will hold information from him, such as in Backseat Drivers From Beyond the Stars, when the Computer casually blurted out, "P.S.; I've located an alien monitoring device within the base." In the cancelled episode Nubs of Doom, the Computer flatly said "I don't want to" when Zim demanded it bring him ear plugs. Sometimes instead of responding to Zim's harkening with its actual voice, it will reply with a few small beeps.
The computer is prone to defects, seen in Invasion of the Idiot Dog Brain. When the computer is proven to be defective, the Artificial Intelligence Brain is replaced with a new one. The Brains resemble human brains, and are plugged into the center of base, after which the new AI flows through data conduits. However, the computer seems to be functional most of the time, save for a fit of unexplained coughing in Walk for Your Lives. Unlike GIR, the Computer is everything but dysfunctional. However, it gets annoyed with its master frequently.
Computer: Something is happening at the front door. Something...horrible!
Computer: Shield in place. PS: I've discovered an alien monitoring device inside the base.
Computer: (Grouchily). Whaaat?
Zim: I don't pay you to contradict me!
Computer: You don't... pay me at all.
Computer: Explosion must expand to it's (Coughs) inevitable size
Zim: What is that size, and why is my computer coughing?
Computer: Master, the Tallest cut the transmission an hour ago.
Zim: My latest plan-
Computer: The latest plan is about to explode.
Gaz: Do you have any video games around here?
Computer: No... not really.
