The Processor Direct Slot (PDS) was an expansion slot used to connect high-speed peripherals and additional CPUs on some early Mac models. It coexisted with NuBus slots and offered a direct connection to the CPU. Despite being largely CPU-specific, it lasted for numerous CPU iterations on the Mac LC. The premises distribution system (PDS) refers to the cabling, racks, and adapters used to link telephone wires within a building or group of buildings to each other and to the telephone company’s external lines.
FAQs About PDS
Are you familiar with PDS or premises distribution system? Here are some frequently asked questions to help you understand it better:
What is PDS?
PDS or premises distribution system refers to the cabling, racks, and adapters that connect telephone wires within a building or group of buildings to one another and to the telephone company’s external lines. It is responsible for distributing telephone services to different parts of a building or facility.
What are the components of a PDS?
A PDS usually consists of cables, patch panels, distribution frames, and connectors. These components work together to distribute telephone services throughout the building or facility.
What is the purpose of PDS?
PDS serves as the backbone of the telephone system in a building or facility. Its main purpose is to provide a centralized location for connecting telephone lines and distributing services to various parts of the building. This makes it possible for people in different offices or locations to communicate with each other through the phone network.
What is the Processor Direct Slot or PDS in Mac computers?
The Processor Direct Slot or PDS is a single expansion slot that was used to connect high-speed peripherals and additional CPUs on some early Mac models. It served as a direct connection to the CPU and coexisted with NuBus slots on certain devices. The PDS was CPU-specific but lasted across various CPU iterations on the Mac LC.
The gist
Knowing the basics of PDS is important for anyone who wants to understand how telephone networks work in buildings and facilities. Whether it’s for a small office or a large-scale facility, having a reliable PDS is crucial for ensuring uninterrupted telephone services. It’s also interesting to note how the term PDS was used differently in the realm of computer technology, specifically with early Mac models.
