Study Notes
CompTIA A+ Technician Roles
- Install and configure personal computer (PC) hardware, attracting many to IT support careers.
- Set up desktop computers and help users select appropriate system configurations and peripheral devices.
- Connect peripheral devices via correct cables and connectors, ensuring efficient communication with the motherboard.
- Distinguish between modern and legacy connection interfaces to support various environments.
Components of a Personal Computer
- Personal computers comprise user-handled peripheral devices and dangerous internal components.
- Peripheral devices include input devices (keyboard, mouse), output devices (monitor, speakers), and external storage.
- Internal components housed in the system case/chassis are the motherboard, central processing unit (CPU), system memory, adapter cards, fixed disks, and power supply unit (PSU).
- Tower form factor cases are oriented vertically, while all-in-one units contain components within the monitor case.
PC Maintenance
- Understand how to open the desktop computer case; tower cases have removable side covers secured by screws or clips.
- Always consult system documentation for proper maintenance steps.
- The front panel provides access to removable media drives, power switches, and status LEDs.
- The rear panel grants access to PSU sockets and I/O ports for peripheral device connection.
Peripheral Device Connectivity
- Input/output (I/O) ports connect devices via peripheral cables; some ports are device-specific, while others are versatile.
- External ports are located on the front or rear of the PC and may be situated on the motherboard or as expansion cards.
Interfaces, Ports, and Connectors
- Hardware ports serve as external connection points for bus interfaces, enabling data transfer to and from devices.
- Connectors are components of peripheral cables that fit into corresponding ports, utilizing designs that prevent incorrect insertion.
- USB ports and various connector types exemplify this versatility in connecting devices like portable hard drives.
Data Measurement and Transfer Units
- Binary data storage and transfer are fundamental in computing; binary digits (bits) represent values of one or zero.
- Storage is often indicated in bytes, where one byte equals eight bits.
- Transfer rates are critical metrics, expressed in units per second, influencing the performance of data transmission between devices.
