Enterprise Architecture is the process of translating business goals and strategy into practical enterprise change by building, communicating and optimising the key requirements, rules and models that describe the desired state of the enterprise and facilitate its change and evolution.
There are many Enterprise Architecture frameworks, each with different strengths and weaknesses. Some focus on modeling existing architecture, others focus on finding solutions to business problems. Here is a list of Enterprise Architecture Frameworks according to category (Wikipedia):
