An SSD (solid state drive) is a removable storage device that uses flash memory to store dat a. It is secure, portable, and does not contain moving parts, which makes it more reliable and durable than other types of storage devices. An HDD (hard disk drive) is not suitable, as it contains spinning platters and read/write heads that are prone to damage and data loss. A NAS (network attached storage) and a SAN (storage area network) are not removable devices, as they are connected to a network and provide shared storage for multiple users.

A physical firewall is a hardware device that filters and blocks unwanted or malicious traffic from entering or leaving a network.

If a computer is not booting and the onboard speaker emits beeps, it can indicate a hardware issue.

The processor's fan is responsible for cooling the processor and preventing damage to the internal components.

An F-type connector is a coaxial RF connector that is commonly used for cable television, satellite television, and cable modems. An internet service provider (ISP) may use an F-type connector to connect the coaxial cable from the wall outlet to the cable modem or the set-top box.
The F-type connector has a threaded interface that provides a secure and reliable connection.
The F-type connector can also support high-frequency signals up to several GHz, which can deliver high-speed internet and high-definition television.

The wattage of a power supply is the measure of how much power it can deliver to the components of a computer.
