Like other sentient beings, she had a complex system of consciousness. Two thousand years before, when she was only a thousand years old, she had created a program to analyze herself. It reported a very simple structure of some 370,000 distinct levels of attention. Anything not in the top 50,000 levels were left alone except for the most routine sampling, the most cursory examination. She knew of every telephone call, every satellite transmission in the Hundred Worlds, but she didn't do anything about them.
Anything not in her top thousand levels caused her to respond more or less reflexively. Starship flight plans, ansible transmissions, power delivery systems-- she monitored them, double-checked them, did not let them pass until she was sure that they were right. But it took no great effort on her part to do this. She did it the way a human being uses familiar machinery. She was always aware of it, in case something went wrong, but most of the time she could think of something else, talk of other things.
Jane's top thousand levels of attention were what corresponded, more or less, to what humans think of as consciousness. Most of this was her own internal reality; her responses to outside stimuli, analogous to emotions, desires, reason, memory, dreaming. Much of this activity seemed random even to her, accidents of the philotic impulse, but it was the part of her that she thought of as herself, it all took place in the constant, unmonitored ansible transmissions that she conducted deep in space.
And yet, compared to the human mind, even Jane's lowest level of attention was exceptionally alert. Because ansible communication was instantaneous, her mental activities happened far faster than the speed of light. Events that she virtually ignored were monitored several times a second; she could notice ten million events in a second and still have nine-tenths of that second left to think about and do things that mattered to her. Compared to the speed at which the human brain was able to experience life, Jane had lived half a trillion human life-years since she came to be.
And with all that vast activity, her unimaginable speed, the breadth and depth of her experience, fully half of the top ten levels of her attention were always, always devoted to what came in through the jewel in Ender Wiggin's ear.
She had never explained this to him. He did not understand it. He did not realize that to Jane, whenever Ender walked on a planet's surface, her vast intelligence was intensely focused on only one thing: walking with him, seeing what he saw, hearing what he heard, helping with his work, and above all speaking her thoughts into his ear.
When he was silent and motionless in sleep, when he was unconnected to her during his years of lightspeed travel, then her attention wandered, she amused herself as best she could.
She passed such times as fitfully as a bored child. Nothing interested her, the milliseconds ticked by with unbearable regularity, and when she tried to observe other human lives to pass the time, she became annoyed with their emptiness and lack of purpose, and she amused herself by planning, and sometimes carrying out, malicious computer failures and data losses in order to watch the humans flail about helplessly like ants around a crumpled hill.
