The optical disk system is a hierarchical system with primary storage on magnetic disk and secondary storage on the optical disks. New files are written to the write cache. Periodically the optical disk archiver copies the files from the write cache to the optical disk. This process also copies the files to the read cache and deletes them from the write cache. The PPPL utilities and libraries that access this data first check the magnetic cache. If the file is not found, the optical disk indices are searched; if the file is found, it is copied to the read cache. The data on the read cache is skimmed by access date.

A physical loop topology, either open or closed, employing two optical fiber signal paths, one in each direction (i.e. counter-rotating) forming a sequence of peer connections between FDDI nodes. When the trunk forms a closed loop, it is sometimes called a trunk ring.

Optical interconnect is a way of communication by optical cables.[1] Compared to traditional cables, optical wires are capable of a much higher bandwidth, from 10 Gb/s up to 100 Gb/s.[2] The technology is currently being researched as a way to link computers to mobile devices,[3] as well as on motherboards and devices within computers

Converts optical signals transmitted via fiber to electrical signals. These electrical signals are then sent to individual subscribers. ONUs are commonly used in fiber-to-the-home (FTTH) or fiber-to-the-curb (FTTC) applications. Silicon Laboratories' proven SLIC and Power over Ethernet solutions offer a one stop shop for high voltage ONU solutions.

In telecommunication, an optical switch is a switch that enables signals in optical fibers or integrated optical circuits (IOCs) to be selectively switched from one circuit to another.

An all-optical fiber-optic switching device that maintains the signal as light from input to output. Traditional switches that connect optical fiber lines are electro-optic. They convert photons from the input side to electrons internally in order to do the switching and then convert back to photons on the output side.

In a telecommunications network, one begins at the terminal site at the customer premises; the access part of the process is the first mile. In essence, it is the part that connects the end user to the first piece of equipment in the network.

It refers to the distribution of the sample across strata by strata size, variance and cost.

The optimal number of people in what can be achieved in a given year compared to the number exceeding the limit and the number that is less than the limit.

A deliberate melding of biological, economic, social, and political values designed to produce the maximum benefit to society from a stock of fish.

A contract giving the holder the right to buy or sell a stated number of shares (normally one hundred) of a particular security at a fixed price within a predetermined period. The Paris market has three main types of option: prime, option and stellage Prime is a call option. If the purchaser decides not to exercise his option (because the price has gone down), he merely has to pay the seller a fee, called a don't, the rate of which is fixed by the Chambre syndicale des agents de change. Option is more similar to the U.S. system and can be a put or call option. The purchaser pays a premium (avec), which is negotiated, whether he exercises the option or not. Stellage is the equivalent of the U.S. straddle.

Option benefits are those derived from the continued existence of elements of the environment that may one day provide benefits for those currently living.

Transaction involving the purchase or sale of options on financial instruments/commodities. They are not true swaps as they primarily entail a series of option trades but are usually treated as swaps.

Options are contracts that give the purchaser of the option the right, but not the obligation, to buy (a call option) or to sell (a put option) a particular financial instrument or commodity at a predetermined price (strike price) within a specific time span (American option) or on a specific date (European option).

Options are contracts that give the purchaser of the option the right, but not the obligation, to buy (a “call” option) or to sell (a “put” option) a particular financial instrument or commodity at a predetermined price (the “strike” price) within a given

There are basically three options as concerns the value of the income element of the resource rent to be taken into account for the calculation of depletion: the whole resource rent is income, the whole resource is depletion and the income element is zero, the income element equals to the rate of return of the natural asset times the value of the stock.

Is a professional certification program offered by the Oracle Corporation. There are three levels of Oracle Certification in several disciplines: Oracle Certified Associate (OCA), Oracle Certified Professional (OCP), and Oracle Certified Master (OCM).

Is a multinational computer-technology corporation that specializes in developing and marketing enterprise software products — particularly database management systems. Headquartered in Redwood City, California, United States, Oracle employs more than 73,201 people worldwide as of 2009[update]. It has enlarged its share of the software market through organic growth and through a number of high-profile acquisitions.

ORT is given to prevent and treat dehydration during episodes of diarrhea by giving a child fluids by mouth. ORT is a threefold strategy that combines administration of a simple solution of sugar and salt with continued feeding through a diarrhea episode and referral when appropriate.

The price quoted at the time the order is placed by the purchaser.

Bilateral arrangement whereby an exporting country (government or industry) agrees to reduce or restrict exports without the importing country having to make use of quotas, tariffs or other import controls.

Ownership share with full voting rights, commonly known as “equities.” Ordinary shares are usually issued in registered form.

Bulk carrier strengthened for the carriage of ore cargoes.

Holistic production management system which promotes and enhances agro-ecosystem health, including biodiversity, biological cycles and soil biological activity.
