Front Running is the unethical practice of a broker trading an equity based on information from the analyst department before his or her clients have been given the information.
For example, analysts and brokers who buy up shares in a company just before the brokerage is about to recommended the stock as a strong buy are practicing front running, or if a broker who buys himself 200 shares in a stock just before his or her brokerage plans to buy a large block of 400,000 shares.
Frontrunning is the illegal practice of a stock broker buying a security for his own account (and thus driving up prices) before filling buy orders previously submitted by his customers.
Similarly, frontrunning may involve the broker selling for his own account (and thus driving down prices) before filling customer sell orders.
"Frontrunning" is sometimes used informally for a broker's tactics related to trading on proprietary information before his or her clients have been given the information.
In computers, the front side bus (FSB) is a term for the physical bi-directional data bus that carries all electronic signal information between the central processing unit (CPU) and other devices within the system such as random access memory (RAM), the memory containing the system BIOS, AGP video cards, PCI expansion cards, hard disks, etc.
Most modern front side buses serve as a backbone between the CPU and a chipset.
With bus speeds increasing rapidly, it may be necessary to run the RAM at a lower frequency than the system bus in order to stay within the limitations of the DRAM modules on the memory stick.
