Patch Cables
Short Ethernet or fiber optic cables used to connect devices to a network via a switch, hub, router, or patch panel. Often used in wiring closets or to link components in close proximity.
Patch Management
The process of acquiring, testing, and installing software updates (patches) to correct vulnerabilities, fix bugs, or enhance features. Critical for security and system stability.
Patch Panel
A hardware assembly with a set of ports used to organize and manage network cables in a structured cabling system. It allows for easy connection changes and cable management.
Path
The location of a file or directory in a file system, typically shown as a string of folders leading to the file (e.g., C:\Users\Name\Documents\File.txt on Windows).
Pattern Lock
A screen lock method where the user draws a pattern on a grid of dots to unlock a device. Common on Android smartphones and tablets.
PCI
(Peripheral Component Interconnect). An older expansion bus standard for connecting peripherals (like network cards or sound cards) to a computer’s motherboard. Has been mostly replaced by PCIe.
PCI DDS
(Payment Card Industry Data Security Standard). A security standard for organizations that handle credit card data. It outlines best practices for securing payment information and maintaining secure systems.
PCIe
(Peripheral Component Interconnect Express). A high-speed expansion bus standard used to connect components like graphics cards, SSDs, and Wi-Fi cards to a motherboard. Offers faster data transfer than PCI.
PCIe 6/8-Pin Power Connector
Connectors used to provide additional power from the power supply to high-performance components like GPUs. A 6-pin provides ~75W; 8-pin provides ~150W.
Peer-to-Peer Network (P2P)
A network where each computer (peer) acts as both a client and a server, sharing resources without a central server. Common in small networks and file-sharing systems.
Performance
The overall responsiveness and speed of a system or component. Affected by CPU, RAM, storage, GPU, and other factors. Monitored using tools like Task Manager or Performance Monitor.
perfmon.msc (Performance Monitor)
A Windows utility that provides real-time and log-based data about system performance, such as CPU usage, memory load, disk activity, and network stats.
Performance Options
A section in Windows System Properties that allows you to adjust system settings like visual effects, processor scheduling, and virtual memory to improve performance.
Peripheral
Any external device that connects to a computer to add functionality. Examples include mice, keyboards, printers, monitors, and external drives.
Permission Propagation
The process where permissions assigned to a parent folder are inherited by its child folders and files. Ensures consistent access control across a directory structure.
Personalization (Windows Settings)
A section in Windows Settings that allows users to customize the appearance of their system, including themes, desktop background, lock screen, colors, fonts, and more.
PII
(Personally Identifiable Information). Any information that can be used to identify a specific individual, such as name, Social Security number, address, phone number, or date of birth. Must be protected due to privacy and security regulations.
PGA
(Pin Grid Array). A type of CPU socket or chip package where the pins are on the processor and inserted into holes in the socket. Commonly used by AMD processors.
Phishing
A social engineering attack where attackers attempt to trick users into giving up personal information (e.g., login credentials or financial data) through fake emails, websites, or messages.
Physical Security
Measures taken to protect hardware and facilities from physical threats like theft, damage, or unauthorized access. Includes locks, surveillance, secure rooms, and access control systems.
Ping
A network utility used to test connectivity between devices. It sends an ICMP echo request and waits for a reply, measuring response time and packet loss.
Pinwheel of Death
A nickname for the spinning beachball cursor on macOS, indicating the system or application is unresponsive or stuck in a loop.
Pipe (|)
A command-line operator used to redirect the output of one command as the input of another. Common in Linux and PowerShell (e.g., ls | grep txt).
Pipeline
A technique in CPUs where multiple instructions are overlapped in execution to improve performance. Different instruction stages (fetch, decode, execute) are handled simultaneously.
