Failback

Failback is the process of moving services back to the original server when it comes back online.

Failover

Failover is the process of moving services from a failed server to another available server.

FAT (File Allocation Table)

A file system that is required for Windows 95 and MS-DOS based computers.

FAT32

A 32-bit file allocation table which was first shipped with Windows 95. FAT32 supports large volumes and is more efficient than the 16-bit FAT system.

FC (Fibre Channel)

Fibre Channel (FC) is an integrated set of standards developed to provide a reliable method for quickly transferring large amounts of data. FC is the recommended method of implementing a shared disk array because of its high bandwidth and high capacity. FC communication can also be used to link workstations, mainframes, and other peripherals.

FCIP

Fibre Channel over IP (FCIP) is an IP-based storage networking technology developed by the Internet Engineering Task Force (IETF). FCIP enables the transmission of data to and from FC storage devices over standard Ethernet copper cabling and switches.

FD (Feasible Distance)

The Feasible Distance (FD) is the lowest total cost to a destination network.

FDDI (Fiber Distributed Data Interface)

A standard produced by the American National Standards Committee for transmitting data on fiber optic lines. FDDI is based on token ring topology and can support a large network over large geographic areas.

FDISK

An MS-DOS utility you can use to create a primary partition or logical drive on a hard disk.

Feasible Distance (FD)

The Feasible Distance (FD) is the lowest total cost to a destination network.

FHSS (Frequency Hopping Spread Spectrum)

A type of signaling method, used by a wireless networking architecture, where a narrow frequency band 'hops' data signals in a predictable sequence from frequency to frequency over a wide band of frequencies. Because FHSS hops between frequencies, it can avoid interference on one cable as it shifts to another. Hopping between frequencies increases transmission security by making eavesdropping and data capture more difficult. Because FHSS shifts automatically between frequencies, it can avoid interference that may be on a single frequency.

Fiber Distributed Data Interface (FDDI)

Fiber optic cable

Fiber optic cable uses glass strands to transmit light pulses rather than electricity to communicate. Thus, it is not susceptible to most forms of interference or wire taping technologies. The biggest disadvantage to fiber optic cable is the high cost of the cable, its components and installation.

Fibre Channel (FC)

Fibre Channel over IP (FCIP)

File Allocation Table (FAT)

A file system that is required for Windows 95 and MS-DOS based computers.

File and Print Services for NetWare (FPNW)

A software component that allows NetWare clients to access file and print services on a Windows 2000 server.

File transfer protocol (FTP)

This protocol provides bi-directional file transfers between two TCP/IP hosts. These hosts must be running FTP software.

File-level security

Security that is applied to individual files and folders on a local computer.

Final partition

The final partition is the domain naming context partition in Exchange 2007. This is used to hold all of the user accounts, groups, and computer accounts. If mail-enabled context is used, then it is stored in the final partition. The domain naming context stores the largest amount of information in a typical employment.

Finger service

A TCP/IP service that allows you to gather system information from a remote computer.

Firewall

A firewall is the best device to deploy to protect your private network from a public untrusted network. Firewalls are used to control traffic entering and leaving your trusted network environment. Firewalls can manage traffic based on source or destination IP address, port number, service protocol, application or service type, user account, and even traffic content.

Firewire

Firewire is a type of media (cable and connectors) that interface between computers to create a network.

Firmware

Computer instructions contained in programmable read-only memory (PROM). Firmware comes as part of a hardware device such as a printer or modem.

Flash updates

With the triggered update method (also known as a flash updates), routers that receive updated (changed) information broadcast those changes immediately rather than waiting for the next reporting interval. With this method, routers broadcast their routing tables periodically, punctuated by special broadcasts if conditions have changed. This method reduces the convergence time.

Floating static route

A floating static route is a static route whose administrative distance has been manually configured to be greater than the administrative distance of dynamic routes; thus making it less desirable than the dynamic route it supports.

Foreign connector

A Foreign connector is a logical object that controls the sending of messages to non-SMTP mail systems or to fax systems.

Forest

In Windows 2000, a forest is collection of one or more domains linked with two-way transitive trusts and sharing a common schema, configuration, and global catalog.

Format

To set up partitions and volumes on a hard disk that will use file system such as FAT or NTFS.

Forward lookup

The query process in which DNS domain names are resolved to IP addresses. In contrast, reverse lookup is the query process in which IP addresses are resolved to domain names.

Forwarder

Forwarders are designated DNS servers that accept and resolve recursively all queries regarding external or off-site addresses. Other servers are configured to send all such queries to the forwarder.

FPNW (File and Print Services for NetWare)

A software component that allows NetWare clients to access file and print services on a Windows 2000 server.

FQDN (Fully Qualified Domain Names)

Host names inside domains that are added to the beginning of the domain name. For example, any name given that is placed in front of Microsoft.com, such as support.Microsoft.com, is a fully qualified domain name.

Frame type

A setting that controls how a network adapter card formats the data you want to send over the network. Ethernet network can operate using various frame types. Ethernet frames are between 64 and 1518 bytes in length. For two computers to communicate, they must use the same frame type. These are the four Ethernet frame types: Ethernet 802.3, Ethernet 802.2, Ethernet II, and Ethernet SNAP.

Frequency Hopping Spread Spectrum (FHSS)

Front end

The client in the client/server computing model. It provides an interface for the user to enter requests, formats user requests so that the server understands them, and displays data from the server.

FTP (File transfer protocol)

This protocol provides bi-directional file transfers between two TCP/IP hosts. These hosts must be running FTP software.

Full Mesh

A mesh topology exists when there are multiple paths between any two nodes on a network. Mesh topologies are created using point-to-point connections. A full Mesh topology connects every node in a point-to-point connection with every other node. Full mesh topologies are usually impractical because the number of connections increases dramatically with every new node added to the network. However, a full mesh topology becomes more practical through the implementation of an ad-hoc wireless network.

Full-mesh iBGP

Full-mesh iBGP is an iBGP network in which each BGP speaker has a neighbor statement containing updated information for all other iBGP speakers in the AS.

Fully Qualified Domain Names (FQDN)
