Many laptops come with Serial ATA (SATA) drives, which incorporate two connectors: a 7-pin data connector and a 15-pin power connector. The bulk of the storage drives in laptops are 2.5 inches wide, though ultra-small laptops and other small portable devices might use a drive as small as 1.8 inches.

Know that SODIMM DDR3 has 204 pins and SODIMM DDR4 has 260 pins. Understand the pin format differences between them and standard DIMMs (used in PCs).

Laptop drives can be accessed from one of three places. The first, and maybe the most common, is from the bottom; this requires removing either the entire bottom cover or an access panel. The second is from underneath the keyboard. And the third is from the side of the laptop where the drive is located, in some kind of caddy. These last two options are much less common than the first.

Wireless networking connections are made with an internal Mini PCIe card that can potentially connect to 802.11a, b, g, n, ac, and ax networks.

Bluetooth devices, such as headsets and phones, over short distances, thus joining or creating a personal area network (PAN)

Bluetooth/WLAN card. External USB and remote controls are also available.

Some laptops are designed with built-in Mini PCIe or M.2 cellular modules. Some telecommunications providers offer cellular connections via USB-based devices as well.

ptop can be secured through the use of cable locks, biometrics, and by disabling NFC.

ear-field communication (NFC) is a technology that allows two mobile devices to “beam” information to each other wirelessly if they are in close proximity

e liquid-crystal display (LCD) is a flat-panel display that consists of two sheets of polarizing material surrounding a layer of liquid-crystal solution. It connects to the motherboard by way of a flex ribbon cable or an all-in-one power/signal cable and gets its power from an inverter board. Most LCD screens are thin-film transistor (TFT) active-matrix displays
