1. Cathode rays (also called an electron beam or e-beam) are streams of electrons observed in vacuum tubes, i.e. evacuated glass tubes that are equipped with at least two metal electrodes to which a voltage is applied, a cathode or negative electrode and an anode or positive electrode

2. Cathode rays are so named because they are emitted by the negative electrode, or cathode, in a tube.

3. To release electrons into the tube, they first must be detached from the atoms of the cathode.

4. In early vacuum tubes (Crookes tubes) this was done solely by the high electrical potential between the anode and the cathode.

5. In modern tubes this is assisted by making the cathode a thin wire filament and passing an electric current through it.

Eye strain - but that's not the only problem

It is not believed that the computer screen, or television screen, damages eyes. There is, however, a condition, "Computer Vision Syndrome", which is associated with the symptoms of eye strain (dry eyes, headache, fatigue, and sometimes some blurring of vision).

While some of these symptoms can occur as a result of prolonged screen viewing, itself; some can be associated with the lighting in the room, the position of the monitor, one's chair height, and other factors that can cause muscles that would otherwise not be tense to be tensed.

Before being too reassured about the monitor's long-term affect on your eyes, however, it is important to know that your eyes may be the least of your problems.

Behind your eyes is the pineal gland. a pea-sized gland that is affected by light and that regulates your body clock, along with your body's chemistry. The pineal gland produces normally produces melatonin (usually at night), and exposure to light (particularly the type of light produced by a computer screen) interrupts this natural process.

Among things said to be affected by too much light, or unnaturally long periods of exposure to it, are the immune system, moods, and even premature aging. Further, there is reason to suspect that the too much exposure to light could result in interfering with the production of a tumor-suppressing hormone.

In a Washington Post article, "Lights at Night Tied to Breast Cancer," by Rick Weiss, the issue of higher rates of breast cancer in women who live in areas that have a high degree of night-time illumination is addressed. Weiss points out that light in the blue part of the spectrum, which is light from computer screens and fluorescent bulbs, is of particular concern.

Computer printer

A computer printer, or more commonly a printer, is a computer peripheral which produces a hard copy (permanent human-readable text and/or graphics) of documents stored in electronic form, usually on physical print media such as paper or transparencies. Many printers are primarily used as local peripherals, and are attached by a printer cable to a computer which serves as a document source. Some printers, commonly known as network printers, have built-in network interfaces (typically wireless or Ethernet), and can serve as a hardcopy device for any user on the network. Individual printers are often designed to support both local and network connected users at the same time.

In addition, a few modern printers can directly interface to electronic media such as memory sticks or memory cards, or to image capture devices such as digital cameras, scanners; some printers are combined with a scanners and/or fax machines in a single unit. Printers that include non-printing features are sometimes called Multifunction Printers (MFP) or Multi-Function Devices (MFD).

A printer which is combined with a scanner can function as a kind of photocopier if so designed. Most MFPs include printing, scanning, and copying among their features. Printers are designed for low-volume, short-turnaround print jobs; requiring virtually no setup time to achieve a hard copy of a given document. However, printers are generally slow devices (30 pages per minute is considered fast; and many consumer printers are far slower than that), and the cost-per-page is relatively high. In contrast, the printing press (which serves much the same function), is designed and optimized for high-volume print jobs such as newspaper print runs--printing presses are capable of hundreds of pages per minute or more, and have an incremental cost-per-page which is a fraction of that of printers.

The printing press remains the machine of choice for high-volume, professional publishing. However, as printers have improved in quality and performance, many jobs which used to be done by professional print shops are now done by users on local printers (desktop publishing). The world's first computer printer was a 19th century mechanically driven apparatus invented by Charles Babbage for his Difference Engine.
