Additional news and announcements included: F8 2011 was held on September 22, 2011. Various things Facebook introduced at the conference included a new profile redesign named 'Timeline' that showed a history of user's activity on their profile, and a broader, more advanced version of the 'Open Graph' protocol. The F8 2011 event was mainly focused on introducing new products, transforming industries, building and growing social applications and product
Fairchild F8 on designing support logic circuits. These goals resulted in a microcomputer with a multiplexed bus architecture, with just two buses for all functions: the time-multiplexed data bus and a 7-bit control bus for synchronizing the system's components relative to the data bus. The functions of the F8 were distributed among several devices resulting in system simplification. In the F8 the control bus regulates the use of the data bus through the use of timing signals and state controls. The phi clock divides the machine cycle into discrete phases depending on the instruction being executed. The five state control lines are
