Computer Hardware
Hardware refers to the physical components of an IT infrastructure. This includes everything from the internal parts of a computer to the external devices that connect to it and the facilities that house it.
End-User Devices
Electronic machines that interact directly with users, such as laptops, desktops, tablets, and mobile phones.
Internal Hardware
Key components inside a computer, including the microprocessor, RAM, hard drive, and motherboard.
External Peripherals
Devices that connect to a computer, such as keyboards, monitors, printers, scanners, and network cards.
Infrastructure Housing
The physical facilities like data centers that contain the hardware, including security and climate control systems.
Network Infrastructure
Network infrastructure enables connectivity and communication between devices. It's defined by its physical layout (topology) and the rules it uses for communication (protocols).

Cloud Computing
Cloud computing allows organizations to rent computing resources—like servers, storage, and software—over the internet instead of owning and managing them on-premises. This offers elasticity and efficiency. Click on a service model to see how responsibilities are shared.
Cloud Service Models: IaaS vs. PaaS vs. SaaS
IaaS
(Infrastructure-as-a-Service)
