Computer memory, a box of memory organized two-dimensionally, is a matrix of information that remains there forever. While computers cannot forget certain information unless it is erased, humans can. Sometimes we forget things intentionally, and sometimes we just repress experiences or memories that we want to forget about. Also, humans can t remember experiences during their first two or three years, a fact known as infantile amnesia. Furthermore humans can distort or construct information.
Humans can change and expand their memory.
Memory is a blessing because without memory we would live minute by minute, with the happenings around us having little, if any, meaning. We would be locked into the present with no past and no future. Luckily, most of us have a good enough memory that makes our existence meaningful. Computers on the other hand are just these big machines, with the limited ability to perform certain tasks. The brain is like a computer.
