The National Research Council (2002) associates the indicators of self-management (self-control, perseverance, stress management and goal-setting) with personal and social assets that facilitate positive youth development in the area of psychological and emotional development.
A Petabyte is approximately 1,000 Terabytes or one million Gigabytes. It's hard to visualize what a Petabyte could hold. 1 Petabyte could hold approximately 20 million 4-door filing cabinets full of text. It could hold 500 billion pages of standard printed text.
By this standard, 8 bits still equal 1 byte, but 1,000 bytes make a KB. This means that a 1 terabyte hard disk holds 1,000 GB or 10 12 bytes. Though the terabyte represents an enormous amount of storage, the petabyte is waiting just beyond. The petabyte is made up of 1,024 (or 1,000) terabytes.
