笔记本 is written with 20 strokes (笔: 10, 记: 5, 本: 5). The animation replays automatically.
笔记本 (bǐjìběn) is a noun meaning 'notebook' — literally a 'pen-notes book' for writing in.
In modern usage it has a second, now-dominant meaning: 'laptop,' short for 笔记本电脑 ('notebook computer'). Context decides which is meant, and when it matters speakers add the qualifier: 我买了一台笔记本 (a laptop, counted with 台) versus 我买了一个笔记本 (often a paper one, counted with 本 or 个).
English speakers should note that the everyday word for a small paper notebook is more often 本子 (běnzi); 笔记本 sounds slightly more specific or, increasingly, points to the computer. It is neutral in register and common in student, office, and shopping contexts.
Note: Neutral. In everyday speech 笔记本 alone increasingly means a laptop; when clarity is needed, people say 笔记本电脑 for the computer and 本子 for the paper notebook.

本子 is the casual, everyday word for a paper notebook or exercise book, and never means a computer. Use 本子 for the physical writing pad; use 笔记本 when you want the fuller word or mean a laptop.
笔记本电脑 is the full, unambiguous term for a laptop. Say it when 笔记本 alone might be misread as a paper notebook.
笔记 (without 本) means 'notes' — the content you write down, as in 记笔记 ('take notes'). 笔记本 is the physical notebook or laptop that holds them.
课本 is a 'textbook' — a printed book you read from. 笔记本 is blank for writing in, or a laptop. Both end in 本 but serve opposite purposes.
