Computer hardware
Computer hardware refers to the collection of the physical components that constitute a computer system. It consists of the tangible parts that can be seen and touched, in contrast to Software, which is the set of instructions that tell the hardware what to do. The hardware provides the fundamental electronic and mechanical infrastructure on which software runs.
All computers, regardless of their size or purpose (from smartphones to supercomputers), rely on hardware to perform input, processing, storage, and output operations.

Overview and Purpose
The purpose of computer hardware is to execute instructions provided by software. Hardware components perform the actual computations, store data, and handle the physical interaction with the outside world (through input and output devices) and other systems (through networking hardware).
The performance, capability, and cost of a computer system are largely determined by its hardware components. Hardware must be compatible and work together, orchestrated by system software like the operating system.
Key Categories of Hardware
Computer hardware can be broadly categorized by its function within the system:
- Processing Components
- These are the components responsible for executing instructions and performing calculations.
- - CPU (Central Processing Unit): The main processor that executes most of the instructions.
- - GPU (Graphics Processing Unit): Specialized processor for rendering images, video, and animations; also used for parallel processing tasks.
- Memory and Storage
- These components store data and instructions.
- - RAM (Random Access Memory): Volatile primary memory used for temporary storage of data and programs currently in use. Data is lost when power is off.
- - ROM (Read-Only Memory): Non-volatile memory containing permanent instructions (like firmware).
- - Storage Devices (Secondary Storage): Non-volatile storage for long-term data retention.
- :: - HDDs (Hard Disk Drives): Use spinning magnetic platters for high-capacity, lower-cost storage.
- :: - SSDs (Solid-State Drives): Use flash memory for faster, more durable storage.
- Input and Output Devices
- Hardware that allows interaction with the user or the external environment.
- - Input Devices: Keyboard, mouse, scanner, microphone.
- - Output Devices: Monitor, printer, speakers, projector.
- Motherboard
- The main printed circuit board that connects all other components, allowing them to communicate with each other. It contains the CPU socket, memory slots, storage connectors, and expansion slots.
- Networking Hardware
- Components that enable the computer to connect to networks.
- - Network Interface Card (NIC): Allows a computer to connect to a wired or wireless network.
- - Routers, Switches (Often external to a single computer, but part of a larger network system).
- Power Supply Unit (PSU)
- Converts electrical power from the wall outlet into the voltages required by the computer components.
Computer Hardware in Pulsed Media Services
Pulsed Media, as an internet hosting service provider offering seedboxes, VPS, and dedicated servers, operates data centers filled with various types of computer hardware. The specific hardware used varies depending on the service type and plan, but it generally consists of enterprise-grade components designed for performance, reliability, and efficiency in a server environment.
Based on publicly available information, the hardware used in Pulsed Media services includes:
CPUs (Processors): Pulsed Media utilizes processors such as Intel Core i5/i7 (often 'T' series for efficiency in some server lines) and AMD Ryzen and EPYC processors.
Usage: These CPUs execute the operating system, run application software (like torrent clients, web servers, media servers), handle network connections, and perform data processing tasks. More powerful CPUs (like AMD EPYC in dedicated servers) provide greater processing power for demanding applications or multiple users/tasks. Intel CPUs with Quick Sync are mentioned for their hardware transcoding capabilities, beneficial for media streaming. RAM (Memory): Servers are equipped with DDR4 and DDR5 RAM.
Usage: Provides temporary, high-speed storage for the OS, running applications, and data being actively processed by the CPU. Sufficient RAM is crucial for multitasking and application performance. Storage Devices: Pulsed Media uses both HDDs and SSDs.
HDDs: Utilizes 3.5" 7200 RPM SATA HDDs (e.g., 8TB, 12TB models). These are typically enterprise-grade drives, designed for 24/7 operation and often used in RAID configurations. Usage: Primarily used for providing large-capacity, cost-effective bulk data storage, which is essential for seedboxes where users store significant amounts of files. SSDs: Uses NVMe SSDs (e.g., 480GB, 2000GB, 4000GB models) and potentially SATA SSDs in some configurations. These offer significantly faster read/write speeds than HDDs. Usage: Often used for the operating system, system files, applications, or performance-sensitive data storage tiers where rapid access speeds are critical (e.g., for databases or high-IOPS workloads). NVMe provides higher performance than SATA SSDs. Networking Hardware: Provides high-speed network connections.
Usage: Enables fast data transfer to and from the internet. Pulsed Media mentions offering connections ranging from 1 Gbps up to 10 Gbps and 20 Gbps, indicating the use of high-capacity network interface cards and related networking infrastructure in their data centers. Motherboards, Power Supplies, etc.: Standard, often enterprise-grade server motherboards, power supply units, chassis, and cooling systems are used to house and power the components reliably.
Usage: Provide the essential physical framework and power distribution needed for the servers to operate continuously and efficiently in a data center environment. The specific configuration and combination of these hardware components determine the performance characteristics of individual seedbox, VPS, or dedicated server plans. Pulsed Media emphasizes the use of enterprise-grade hardware for reliability and performance tailored to hosting services.
