TPM stands for Trusted Platform Module, which is a hardware component that securely stores encryption keys and other sensitive data12. TPM can be used to enable hard drive encryption, which is a technology that encrypts the data stored on a hard drive using sophisticated mathematical functions34. Hard drive encryption protects the data from unauthorized access in case the hard drive is lost, stolen, or tampered with.

To terminate an RJ45 port, a technician should use a punchdown tool. This tool is specifically designed to insert and cut (terminate) the wires into a patch panel, keystone jack, or a network surface mount box. The punchdown tool ensures that the wire is properly seated in the terminal block and that the connection is secure. It also trims the excess wire during the termination process, which is not a function that cable testers, toner probes, or cable strippers are designed to perform.

In the SaaS (Software as a Service) model, the service provider manages the infrastructure, platforms, and software applications, including maintenance tasks such as application patching. Users access the applications over the internet, and the provider is responsible for ensuring the software is up to date, secure, and performing optimally. This model contrasts with IaaS (Infrastructure as a Service) and PaaS (Platform as a Service), where the customer has more control and responsibility over the environment and may need to manage patching for applications they develop or install.

For laptops, the most common type of RAM used is Small Outline Dual Inline Memory Module (SODIMM) due to its smaller size compared to DIMMs used in desktops. DDR5 is the latest generation of RAM, offering higher speed and efficiency. ECC (Error-Correcting Code) DIMM DDR5 and Registered DIMM DDR5 are typically used in servers and high-end workstations for error correction and stability, not in standard laptops. High latency DDR5 is not a desirable specification for RAM as lower latency is preferred for faster performance.
