220-1202

The CompTIA A+ 220-1202 exam, covering the core hardware and operational aspects of computers, focuses on these main points:

I. Mobile Devices:

• Hardware: Understanding mobile device components, including processors, memory, storage, and input/output devices. Troubleshooting hardware issues related to these components.
• Operating Systems: Familiarity with iOS, Android, and Windows Mobile operating systems, including their features, configurations, and troubleshooting.
• Security: Implementing mobile device security measures, such as password protection, encryption, and remote wipe capabilities. Understanding mobile malware and its prevention.
• Networking and Connectivity: Understanding how mobile devices connect to networks (Wi-Fi, cellular, Bluetooth) and troubleshooting connectivity issues.

II. Networking:

• Fundamentals: TCP/IP model, network topologies (bus, star, mesh, ring), network devices (routers, switches, hubs), IP addressing (IPv4 and IPv6), subnetting.
• Wireless Networking: 802.11 standards (a, b, g, n, ac, ax), wireless security protocols (WPA2, WPA3), configuring wireless networks, troubleshooting wireless connectivity problems.
• Network Troubleshooting: Using diagnostic tools to identify and resolve network connectivity issues. Understanding common network problems and their solutions.

III. Hardware:

• Motherboards: Understanding motherboard components, including chipsets, BIOS/UEFI, expansion slots, and connectors. Troubleshooting motherboard issues.
• Processors (CPUs): Understanding CPU architecture, types (x86, ARM), and troubleshooting CPU-related problems.
• Memory (RAM): Understanding RAM types (DDR, SDRAM), memory modules, and troubleshooting memory issues.
• Storage: Understanding different storage types (HDD, SSD, NVMe), RAID configurations, and troubleshooting storage device problems.
• Power Supplies: Understanding power supply components, voltages, and troubleshooting power supply issues.
• Peripherals: Understanding various peripherals (printers, scanners, cameras, etc.), their connection types, and troubleshooting related problems.

IV. Operating Systems (OS):

• Windows: Understanding Windows operating system fundamentals, including file systems, user accounts, permissions, and troubleshooting various Windows-related issues.
• Other OS: While Windows is heavily emphasized, a general understanding of other OS fundamentals (like Linux and macOS) is beneficial.
• Virtualization: Basic understanding of virtual machines and hypervisors.

V. Troubleshooting and Maintenance:

• Diagnostic Tools: Understanding and using various diagnostic tools to troubleshoot hardware and software problems.
• Preventive Maintenance: Performing preventative maintenance tasks to keep systems running smoothly.
• Safety Precautions: Understanding safety procedures when working with computer hardware.

VI. Security:

• Threats: Understanding various security threats such as viruses, malware, phishing, and social engineering.
• Protecting Data: Implementing security measures to protect data, including passwords, encryption, and access controls.
• Software Updates: The importance of installing updates and patches to fix security vulnerabilities.

This list encompasses the key areas. The actual exam will test your practical knowledge and troubleshooting skills through a variety of question types, including multiple-choice, performance-based simulations, and drag-and-drop scenarios.
