Working principle of a laptop
CHAPTER ONE
1.0
INTRODUCTION
A computer can be defined as an electronic device which accepts data from the user, processes the data to become an information, share or memorize and later release them to the user.
In education, business, manufacturing, communication, scientific research, medicine, entertainment and home, the change brought by the extraordinary innovation and proliferation of information technology have been swift, and profound. Computer as a basic tool in the world has evolved in so many ways which facilitates high efficiency in all the sectors mention above.
A laptop can also be called notebook because it is a personal computer for mobile use. A laptop integrates most of the typical components of a desktop computer, including a display, a keyboard, a pointing devices (a touchpad, also known as a track pad), and speakers into a single unit. A laptop is powered by mains of electricity via and A.C adapter and can be used away from an outlet using a rechargeable battery.
Portable computers, originally monochrome CRT based and developed into the modern laptops and were originally considered to be a small inch market,

mostly for specialized field applications such as the military, accountants and sales representatives. Portable computer become larger and of better quality, laptops became very widely used for all sorts of purpose.
1.1
BACKGROUND OF THE STUDY / PROJECT
Laptop computer is based on two parts which are hardware and software.
They are the background of a laptop computer.
1.1.1 HARDWARE
Hardware refers to the mechanical, electrical and electronic parts of the computer.
In short, they are physical parts of the computer i.e parts that you can see, touch, and hold.
Hardware includes: keyboard, V.D.U or screen, the C.P.U, mouse, modems, cables, to mention a few.
Computer hardware could be divided into three basic units.
- Input unit
- Central processing unit
- Output unit
