Regarding your question, in the Knowledge Area "Project Communication Management" in the PMBOK
Chapter 10.1.2.4 Communication Methods defines the following:
Push communication
Sent to specific recipients who need to recheive the information. This ensures that the information is distributed but does not
ensure that it actually reached or was understood by intended audience. Push communication include letters, memos, reports, emails, faxes, voice mails, blogs, press releases, etc.
Pull communication
Used for very large volumes of information, or for very large audience, and requires the recipient to acess the communication content at their own discretion.These methods include intranet sites, e-learning, lessons learned database, knowledge respositories, etc.
