Cathode Ray Tube. Technology used by many monitors that scans an electron beam Across blobs of phosphor to create an image on your screen. The beam scans many times faster than your eye Can perceive creating a "still" image to you. However, you may be Able to notice a "flicker" out of the corner of your eye on some monitors Because the refresh rate, or times the beam moves across the monitor, is slow Enough to be perceived by the more sensitive photoreceptors at the edges of your Eye. A monitor should refresh faster than 72hz in order to have this flicker go Away.

Cathode Ray Tube, what is now called a computer monitor (see VDT).

athode- ay ube] The video monitor component of a terminal.

The CRT is a tube found in most televisions, monitors, and video monitors. Once heated, it creates images by emitting a beam of electrons that hit a phosphor-coated surface. The glow of the surface is dependent on the beam's intensity. Each CRT uses deflection circuitry to control the beam's movement.

CHARITABLE REMAINDER TRUST. The general term used to describe a separate trust arrangement between the donor and the trustee of the donor's choosing, the terms of which must conform to the 1969 Tax Reform Act that established this charitable vehicle. This trust may be either an annuity trust or unitrust (see separate definitions). This trust must have a charitable intent, is irrevocable and receives a partial income tax deduction in the year of the gift. It also produces income from the property transfer; and at the end of the trust, the remaining principal is distributed to the charity (thus the remainder defines what type of charitable trust). This trust allows the donor to choose their trustee, payout rate, term (number of years, life or lives, or combination of the two), investment strategy, frequency of payment and who is the ultimate charitable beneficiary.

Charitable Remainder Trust. The donation of property or money to a charity, whereby the donor reserves the right to use the property or to receive income from it for a specified time. When the agreed-upon period is over, the property belongs to the charitable organization. The donor in turn receives various tax deductions and tax advantages. The most common CRTs are the charitable remainder annuity trust (CRAT) and the charitable remainder unit trust (CRUT).

Chinese Remainder Theorem. A theorem about the unique factorization of integers which can be utilized to speed up the computation of some cryptographic algorithms.

Cardiac Resychronization Therapy

a therapy where electrical pulses are delivered to the ventricles to coordinate the contraction of the heart chambers, thereby increasing efficiency of the heart.

Corneal Refractive Therapy. A process of reshaping the cornea using specially designed gas permeable contact lenses. The patient wears the lenses through the night to shape the cornea, then goes throughout the day without the need for a prescription. Go to Top

Critical Response Team

Combat Repair Team

Casualty Response Team

Change Review Team. A change review team is the group of technical contributors that a particular consolidation team may charter to manage the day-to-day business of evaluating the technical risk and merit of proposed changes". Typical evaluations handled by the CRT are the integration requests for fixes for groups of bugs; project integrations are usually managed by the consoldation's release team.

Criteria referenced testing

Criterion Referenced Tests. Tests which measure an individual's performance against a specific standard or criterion; used to measure actual learning or diagnose instructional needs.

Criterion Referenced Test. Assessment instrument used to diagnose skill levels achieved on each of several specific tasks applicable to a particular situation in a given classroom or school.
