Seasonal decorations of greenery have embellished European Christmas celebrations for centuries. Laurel's association with the season can be traced back even further, however. The Romans celebrated their new year festival, Kalends, by adorning their homes and temples with evergreen branches. Both the Greeks and the Romans crowned the victors of their athletic and other contests with wreaths of laurel, since the laurel branch served as a symbol of victory. In later times northern Europeans gathered laurel, or bay, for their Christmas garlands. In the seventeenth century the English poet Robert Herrick (1591-1674) noted that, according to local custom, "Rosemary and baies [bays] that are most faire were stuck about the houses and the churches as Christmas decorations." Christian authorities explained this use of laurel with reference to its ancient association with victory, declaring that when used in Christmas trimmings the fragrant leaves represented the triumph of Jesus Christ.

a small part of a sea, gulf, lake, or reservoir separated from open water by areas of dry land. Local conditions determine the hydrological characteristics of a bay, which differ somewhat from the characteristics of the nearby waters. Usually bays form good harbors for vessels (Gelendzhik and Novorossiisk bays in the Black Sea, the Golden Horn in the Bosporus Strait, and other bays).

What does it mean when you dream about a bay?

A body of water often represents the unconscious, so the shoreline of a bay indicates the threshold between conscious and unconscious. As an open semi-circle, a bay can also represent female sexuality. Additionally, it might refer to idioms such as to “keep one at bay.” (See also Beach).

(As in an aeroplane "cargo bay") A space in a cabinet into which a device of a certain size can be physically mounted and connected to power and data.

Common examples are a "drive bay" into which a disk drive (usually either 3.5 inch or 5.25 inch) can be inserted or the space in a docking station where you insert a notebook computer or laptop computer to work as a desktop computer or to charge their batteries, print or connect to the office network, etc.

Bay Networks

A networking products company formed in 1994 as a merger of SynOptics Communications, Santa Clara, CA and Wellfleet Communications, Billerica, MA. The name was derived from their locations: the California Bay and the Bay State. At the time of the merger, SynOptics was number #1 in hubs, and Wellfleet was number #2 in routers. In 1998, Nortel acquired Bay and made it a division of the company, then later absorbed it entirely. In addition to an extensive product line for enterprises and carriers, Bay Networks brought thousands of experienced IP professionals into Nortel. The acquisition so profoundly affected the company that it officially added "Networks" to its corporate identity to become "Nortel Networks." See Nortel Networks.

drive bay

A cavity for a disk drive in a computer cabinet. Drive bays today are typically 5.75" wide, which accommodate 5.25" optical drives and 5.25", 3.5" and 2.5" storage drives. See hard disk, SSD and Device Bay.

Half-Height vs. Full-Height
Drive bays today are "half-height" drives that are 1 5/8" high. The half-height designation is because the bays used to be 3.25" high ("full-height") to hold the floppy and hard drives in the first personal computers.

Four Half-Height Drive Bays
This computer has four half-height drive bays, three of which are empty below the DVD drive on top.

Full-Height Drives
CP/M computers in the early 1980s had two full-height drives. The first personal computer hard drives held 5MB. Today's entry-level smartphone has 3,000 times as much storage.
