More Description

The pages in a notebook are often lined, so that you can write neatly. You might keep one for writing to-do lists or thoughts (like a journal), or your notebooks might all be large binders full of class notes and math problems. Notebooks can be bound like books, or with a spiral metal or plastic binding, or consist of loose pages in a three-ring binder. Another, newer kind of notebook is a slim, lightweight laptop computer.

A laptop computer that weighs roughly from four to seven pounds. The term originated when laptops were routinely more than 10 pounds, and lighter models were placed in a special "notebook" category. In practice, notebooks and laptops are synonymous. Portable computers that weigh less than four pounds may be called a "subnotebook" or "mini laptop." For features of a portable computer, see laptop. See subnotebook, netbook, MacBook and Ultrabook.
