CompTIA A+ CORE 1 220-1201 Course Notes

Flashcards covering key concepts and terminology from Professor Messer's CompTIA A+ Course Notes.

Hypervisor\n\n

A virtual machine manager that allows multiple operating systems to run on a single hardware platform with efficient resource allocation.\n\n

RAID (Redundant Array of Independent Disks)\n\n

A data storage virtualization technology that combines multiple physical disk drive components into one or more logical units for redundancy or performance improvement.\n\n

TCP (Transmission Control Protocol)\n\n

A connection-oriented protocol that establishes a reliable communication channel, ensuring ordered delivery and error recovery.\n\n

UDP (User Datagram Protocol)\n\n

A connectionless protocol that allows for faster data transmission without guarantees of reliability, making it suitable for real-time applications.\n\n

NFC (Near Field Communication)\n\n

A short-range wireless technology allowing data transfer between devices when they are brought within a few centimeters of each other.\n\n

eSIM\n\n

An embedded SIM card that is soldered onto the device's motherboard and cannot be removed, offering a compact alternative to traditional SIM cards.\n\n

S.M.A.R.T. (Self-Monitoring, Analysis, and Reporting Technology)\n\n

A monitoring system integrated into hard drives that detects and reports various indicators of drive reliability.\n\n

BYOD (Bring Your Own Device)\n\n

A policy allowing employees to use their personal devices for work purposes, which poses security challenges for organizations.\n\n

MDM (Mobile Device Management)\n\n

A software solution that enables the centralized management of mobile devices, controlling policy enforcement and security.\n\n

SSD (Solid State Drive)\n\n

A type of data storage device that uses integrated circuit assemblies to store data persistently, offering faster data access compared to traditional hard drives.\n\n

VPN (Virtual Private Network)\n\n

A technology that creates a secure connection over a less secure network, allowing users to send and receive data as if they were directly connected to a private network.\n\n

IoT (Internet of Things)\n\n

A network of interconnected devices that communicate and exchange data over the internet, allowing for smarter and more efficient environments.\n\n

Blockchain\n\n

A decentralized ledger technology that records transactions across multiple computers, ensuring the integrity and security of data without a central authority.\n\n

Cloud Computing\n\n

The delivery of computing services over the internet, allowing for on-demand access to storage, processing power, and applications, without the need for local infrastructure.\n\n
