What’s This OSI Model all About?
The OSI model (Open Systems Interconnection) is well known by all IT professionals, and is often referred to it by its seven layers. The OSI model characterizes computing functions into a universal set of rules and requirements in order to support interoperability between different products and software. The model uses these seven layers to help give a visual description of what is going on with a particular computing system (networking, hardware, software, etc.). Data must travel down the seven layers of the OSI model on the sending device and then travel up the seven layers on the receiving end. This model helps IT professionals efficiently and effectively troubleshoot a problem. Is it a physical issue, an application issue, or is it somewhere in between?
Why is this important? It’s not particularly interesting if you’re not working in the IT industry, so we decided to make a model that’s more relevant to products and services you’ll get from Compass Consulting – and delivered in a way that sets us apart from other IT providers.
