Refer to the worksheet in ITEssentials: PC Hardware and Software Labs and Study Guide, Third Edition (ISBN 1-58713-198-6). You can perform this worksheet now or wait until the end of the chapter.Identify and Describe the Components of aLaptopCommon laptop features include the following:■■■■■■They are small and portable.They have an integrated display screen in the lid.They have an integrated keyboard in the base.They run on AC power or a rechargeable battery.They support hot-swappable drives and peripherals.Most laptops can use docking stations and port replicators to connect peripherals.In the following sections, you look closely at the components of a laptop. You also examinea docking station. Remember, laptops and docking stations come in many models.Components can be located in different places on different models.After completing these sections, you will meet these objectives:■■■Describe the components found on the outside of the laptopDescribe the components found on the inside of the laptopDescribe the components found on the laptop docking stationDescribe the Components Found on the Outside of theLaptopLaptop and desktop computers use the same types of ports so that peripherals can be interchangeable.These ports are specifically designed for connecting peripherals and providingnetwork connectivity and audio access.Ports, connections, and drives are located on the front, back, and sides of the laptop becauseof the compact design.
