Fast Ethernet is a local area network (LAN) transmission standard that provides a data rate of 100 megabits per second (referred to as "100BASE-T"). Workstations with existing 10 megabit per second (10BASE-T) Ethernet card can be connected to a Fast Ethernet network.

Fiber Connectivity (FICON) is a high-speed input/output (I/O) interface for mainframe computer connections to storage devices.

Flash memory is a special type of EEPROM (electrically erasable programmable read-only memory) that can be erased and reprogrammed in blocks instead of one byte at a time. Many modern PCs have their BIOS stored on a flash memory chip so that it can easily be updated if necessary. Flash memory is used in digital cellular phones, digital cameras, LAN switches, PC Cards for notebook computers, digital set-up boxes, embedded controllers, and other devices.

A system designed to prevent unauthorized access to or from a private network.

Basically, a firewall, working closely with a router program, examines each network packet to determine whether to forward it toward its destination.

Firewalls can be implemented in both hardware and software, or a combination of both. Firewalls are frequently used to prevent unauthorized Internet users from accessing private networks connected to the Internet, especially intranets

A firewall is a set of related programs, located at a network gateway server, that protects the resources of a private network from users from other networks.

Flow Control is the process of adjusting the flow of data from one device to another to ensure that the receiving device can handle all of the incoming data. This is particularly important where the sending device is capable of sending data much faster than the receiving device can receive it.

Flow control can be implemented in 3 ways

1. Hardware flow control using RTS/CTS signal
2. Software flow control using XON/XOFF signal
3. Combination of above two

FreeBSD is a popular and free version of UNIX that runs on Intel microprocessors. It is distributed in executable and source code form. The source code enables ambitious users to actually extend the operating system.

For an oscillating or varying current, frequency is the number of complete cycles per second in alternating current direction. The standard unit of frequency is the hertz, abbreviated Hz.

File Transfer Protocol (FTP), a standard Internet protocol, is the simplest way to exchange files between computers on the Internet. Like the Hypertext Transfer Protocol (HTTP), which transfers displayable Web pages and related files, and the Simple Mail Transfer Protocol (SMTP), which transfers e-mail, FTP is an application protocol that uses the Internet's TCP/IP protocols.
