What should you do with a swollen lithium-ion battery?

Stop using it and arrange qualified service. Do not press, puncture, or attempt an improvised repair.

How does a docking station differ from a port replicator?

A docking station may provide power, networking, displays, and peripheral connections through one connection; a port replicator primarily expands available ports.

What does a USB-C connector alone not guarantee?

USB-C identifies a connector shape; it does not guarantee specific data, display, or charging capabilities. Check the device and accessory specifications.

What role does a SIM or eSIM play in cellular service?

A SIM or eSIM identifies the subscriber. Cellular service also depends on coverage, account status, device compatibility, and the data plan.

What should you verify before using a phone as a hotspot?

Tethering or hotspot shares a phone’s internet connection. Check that the carrier plan permits it and monitor mobile-data limits or charges.

Why is synchronization not necessarily a backup?

Synchronization keeps selected information consistent across devices, but it can also propagate deletions or unwanted changes. It is not automatically a backup.

Where does a Type 1 hypervisor run?

A Type 1 hypervisor runs directly on the physical host hardware.

Where does a Type 2 hypervisor run?

A Type 2 hypervisor runs as an application on a conventional host operating system.

How do containers differ from full virtual machines?

Containers package applications and dependencies while sharing the host operating-system kernel. Full VMs each run a guest operating system.

What does Infrastructure as a Service (IaaS) provide?

IaaS provides virtualized resources such as VMs, networks, and storage; the customer manages much of the operating system and software stack.

What does Platform as a Service (PaaS) let a customer do?

PaaS provides a managed application-development or hosting platform. The customer deploys applications without managing the underlying servers and operating systems.

What characterizes Software as a Service (SaaS)?

SaaS provides a provider-hosted application, usually accessed through a browser or app, while the customer manages relatively little of the underlying infrastructure.
