Computers' consciousness

It is said that computers lack consciousness, lack awareness of what they are doing, and that is largely so but how much do humans and animals have consciousness then? If one is doing something with a foggy head or likewise low capacity to handlke many things at the same time, like is typical if one's capacity to handle seen information is low, concentrated only to the central points of the things at hand, then one just does some step of the thing to be done and then next and so on and has some points in use of what one is doing but some are obscure or just stored in some place in one's memory. If a computer has a goal and does the steps it is commanded to do then it does quite much the same. Is the difference in whether one has a seen picrture of the thing in question or not. One's picture of the things in question is not always well understood: maybe one is bored and staring absentmindedly, waiting for some certain things. Or the one has a good picture of the environment and one knows what the phenomena in it are and what one is oneself going to do and how. Often one has something in between, like standing somewhere where people pass by every now and then, one's posture may reflect the last passerby, her/his style and where he/she went, and who is near or where the different routes lead, but that information isn't well analyzed, it is something which comes to use when the phenomena come near, come to be central themes of the happenings, like when choosing a certain road to travel and entering that sphere of life that is in that direction. So it is much like a computer storing information on it's memory places and fetching it when the subject is at hand. The difference to fully capable human in consciousness is largely the understood picture of the environment and one's own mode of action being tuned to all the sides of the situation in right proportions and in ways that make sense also from the point of view of how humans and the things in the environment work and what is the idea in each thing.
