The answer is "it depends on the nature of the business".

Generally speaking, CRM covers front office business processes, while ERP covers back office business processes. However, these kinds of software are often vertically integrated (i.e. targeted at specific kinds of organisations/industries), and so at times the terms are used interchangeably.

CRM is primarily focused on the sales & marketing processes. ERP is commonly is primarily focused on getting the things you need to sell ready to sell (e.g. purchasing, manufacturing, hiring/developing employees/contractors) and managing the ordering/billing/delivery aspects of the sale. Both typically overlap in capabilities around sales.

CRM and ERP typically have different perspectives. CRM is typically customer-oriented, intended to create and build/maintain relationship with customers through managing the interaction with the customer, both directly and through sales/service partners. ERP is typically product-oriented, intended to make sure the organisation and its suppliers work together efficiently and effectively (from the point of view of being ready to meet market demand).

As a result, while large organisations typically have both, smaller organisations will have a variant of one or the other as their primary system. Smaller organisations where systemising the prepation and delivery of product is the focus will use an ERP (e.g. manufacturing), while smaller organisations where the relationship is the focus (e.g. close collaboration with the customer is required to get the sale and/or deliver the right product so the customer will become a repeat customer) will use a CRM (e.g. professional services).

Getting back to vertical integration, if a particular CRM is targeted at the professional services industry, it may include personnel/project management even though that's normally an ERP function; conversely, if an ERP is targeted at FMCG distributors, it may include sales partner program management so you can manage you distribution channels even through that's a CRM function.

Hope that helps.

Would that mean that the speed of light in our universe is a function of the speed of expansion of the universe's event horizon?

An in-house data centre need not have an automated resource provisioning and usage metering capability, utility fashion (i.e. for SaaS, automated provisioning and deployment of data sets into your application instance(s) and reporting on their usage by relevant metrics such as users or data throughput; for PaaS, automated provisioning and deployment of application components and instances thereof and their usage by relevant metrics such as messages processed or concurrent transactions; for IaaS, automated provisioning and deployment of virtual machines and their usage by relevant metrics such as CPU time or IOPS). It can be automated, it can be manual, or a combination of both.
A real private cloud does.

An in-house data centre is your facility, whether leased, built or bought.
A private cloud need not be. As long as only you are not sharing resources at the level being sold (e.g. for SaaS, nobody else is in your application instance; for PaaS, nobody else is processing transactions on the same transaction processor; for IaaS, nobody else is running VMs on the same physical hardware), you need not be the only customer in the facility/floor/room/cage/aisle/rack.

In short, an in-house data centre is not automatically a private cloud, nor is a private cloud automatically in an in-house data centre.

Maybe this traffic and storage free-riding by other applications has hastened its demise.

So they want to use the single most unreliable hardware component in my PC to identify it and potentially control whether I have access to my online resources?

Over the years, the graphics card is the one thing that consistently ends up cooking itself. Never mind that something as simple and common as a firmware version change or a driver version change can and does modify its behaviour.
