Study Notes

Smart Card Readers

Two types: Contact readers require physical insertion of the card; contactless readers utilize radio frequency for communication.

SODIMM Memory

Laptops use Small Outline Dual In-line Memory Modules (SODIMM), unlike desktops which use DIMM.
SODIMMs are classified by DDR version; compatibility varies by laptop model.
RAM is accessed via slots located under the laptop's cover, sometimes necessitating removal of the keyboard.

Laptop Hardware Replacement

Customer-replaceable units (CRUs) include components like batteries and RAM; field-replaceable units (FRUs) include motherboards and displays.
Common repairs include diagnostics, data recovery, keyboard and fan replacements, and internal cleaning.

Battery Replacement Indicators

Signs for battery replacement: failure to hold charge, overheating, or leakage.
Replacement batteries must meet or exceed original specifications regarding form factor, voltage, and power ratings.

Internal Storage and Optical Drives

Laptop drives are smaller than desktops, typically 1.8 in. or 2.5 in. wide.
Most storage devices are CRUs and accessed through removable covers or by removing the keyboard.

Cell Phone Parts

Field-replaceable parts in cell phones include memory, SIM cards, and batteries.
SIM cards authenticate devices and store user data; Secure Digital (SD) cards expand memory.

Wired Connectivity for Mobile Devices

Mini-USB, USB-C, micro-USB, and Lightning cables facilitate charging and data transfer across devices.
USB-C allows connection in either direction.

Wireless Communication Methods

Wireless options include Wi-Fi, NFC for short-range communication, IR for remote control, and Bluetooth for short-distance data exchange.
Smartphones can share internet connections through tethering.

Basic Troubleshooting Steps for Laptops and Mobile Devices

Problem-solving sequence: Identify the issue, theorize causes, test theories, enact resolutions, verify functionality, document findings.
For laptops: look for issues with battery charge, cable connections, or RAM; for mobile devices, consider battery function and dirt in ports.

Key Terms and Commands

New terms include smartwatch, tablet, smartphone, fitness tracker, Bluetooth, SIM card, SD card, and various generations of cellular technology (1G to 5G).
Important commands include application commands for email processing like SMTP, POP3, and IMAP.

Summary of Essential Features

Understanding the features, configurations, maintenance, and troubleshooting methods of laptops and mobile devices is crucial for effective device management.
