Function of X plates in cathode ray oscilloscope?
- cathode - emits electrons which will become the beam
- control grid - adjustment of beam current and thus brightness on screen
- focus grids - focusing beam to sharp point on screen to form small dot
- x plates - deflect beam left/right
- y plates - deflect beam up/down
- anode - aquadag coating (baked on graphite applied in water suspension) on the inside of the CRT's cone, both accelerates the beam and collects the electrons that rebound from the screen
Note: the grids in a CRT are different from the grids in ordinary vacuum tubes: in a CRT the grids are just round holes in metal disks that surround the beam, in ordinary vacuum tubes the grids are actual wire grids in the direct path of electron flow.
The H represents your hard drive. This acts like a storage facility. Things you download are stored in there! And you only have a certain amount of memory that can be used, before you can't download anymore. But you can always delete stuff from it.

Did they have computers in the 60's?
In the 1960's there were no personal computers, and computers were used only by large, wealthy organizations, mainly banks and governments. Banks had a form of computerized accounting in which punched cards were used to keep track of individual accounts. Governments needed to do calculations for such things as the Apollo space program. Most people never saw a computer, in that decade. Few people even had calculators, which were just being introduced at the end of the decade. Adding machines existed, but they too were large, expensive, and clumsy to use. It was the dawn of the computer age.
What device changes electrical energy into light and sound energy?
A TeleVision because to produce an image, it needs to have some light shining from the back of the screen, therefore emitting light and it has speakers on it to produce sound all from electricity.
How to Connect two pc's to one monitor?

Can your iPod shuffle work on iHome?
Im pretty sure that your ipod touch will work with ihome ih5 as the speakers are made for ipods they work with any type of ipod out there. If on the cover/box of the ihome ih5 says that it will only work with ipod nano ipod video etc. and ipod touch is not on there it only means that the speakers were made before the ipod touch came out and Im 100% sure that it will work with your ipod. I bought speakers for ipod (i also have an ipod touch) and the information on the box didn't include ipod touch as the electronic that the speakers will work with but my ipod works perfectly with the speakers and I have no problems with it.

What is cool about the telephone?
The telephone is a telecommunications device which is used to transmit and receive sound (most commonly speech). Most telephones operate through transmission of electric signals over a complex telephone network which allows almost any phone user to communicate with almost anyone. Two types of communication are essential - external and internal. · Externalcommunication reaches out to the customer to make he or she aware of your product or service and to give the customer a reason to buy. This type of communication includes your brochures, various forms of advertising, contact letters, telephone calls, Web sites and anything else that makes the public aware of what you do. Image is extremely important in external communication; your telephone message should reflect your professionalism. Professional telephones are a full-service external telecommunications solution for both small and large companies such as, · Telephone Answering Service · Voicemail · Order Taking · Scheduling · Live Chat · Fax · Live voice · Setting Appointments · Outbound Client Surveys · Internalcommunication is essential to attracting and retaining a talented staff. You must provide the direction for the company by consistently communicating that message; you must motivate your staff through various forms of communication, which can include awards, newsletters, meetings, telephone calls and formal and informal discussions.

Linear equations in two variables
A common form of a linear equation in the two variables xand y is
where m and b designate constants. The origin of the name "linear" comes from the fact that the set of solutions of such an equation forms a straight line in the plane. In this particular equation, the constant m determines the slope or gradient of that line, and the constant term b determines the point at which the line crosses the y-axis, otherwise known as the y-intercept.
Since terms of linear equations cannot contain products of distinct or equal variables, nor any power (other than 1) or other function of a variable, equations involving terms such as xy, x2, y1/3, and sin(x) are nonlinear.
Forms for 2D linear equationsLinear equations can be rewritten using the laws of elementary algebra into several different forms. These equations are often referred to as the "equations of the straight line." In what follows, x, y, t, and θ are variables; other letters represent constants (fixed numbers). General (or standard) formIn the general (or standard[1]) form the linear equation is written as:where A and B are not both equal to zero. The equation is usually written so that A ≥ 0, by convention. The graph of the equation is a straight line, and every straight line can be represented by an equation in the above form. If A is nonzero, then the x-intercept, that is, the x-coordinate of the point where the graph crosses the x-axis (where, y is zero), is C/A. If B is nonzero, then the y-intercept, that is the y-coordinate of the point where the graph crosses the y-axis (where x is zero), is C/B, and the slope of the line is −A/B. The general form is sometimes written as: where a and b are not both equal to zero. The two versions can be converted from one to the other by moving the constant term to the other side of the equal sign. Slope--intercept formwhere m is the slope of the line and b is the y-intercept, which is the y-coordinate of the location where line crosses the y axis. This can be seen by letting x = 0, which immediately gives y = b. It may be helpful to think about this in terms of y = b + mx; where the line passes through the point (0, b) and extends to the left and right at a slope of m. Vertical lines, having undefined slope, cannot be represented by this form. Point--slope formwhere m is the slope of the line and (x1,y1) is any point on the line.The point-slope form expresses the fact that the difference in the y coordinate between two points on a line (that is, y − y1) is proportional to the difference in the x coordinate (that is, x − x1). The proportionality constant is m (the slope of the line). Two-point formwhere (x1, y1) and (x2, y2) are two points on the line with x2 ≠ x1. This is equivalent to the point-slope form above, where the slope is explicitly given as (y2 − y1)/(x2 − x1).Multiplying both sides of this equation by (x2 − x1) yields a form of the line generally referred to as the symmetric form:
Intercept formwhere a and b must be nonzero. The graph of the equation has x-intercept a and y-intercept b. The intercept form is in standard form with A = 1/a and B = 1/b. Matrix formUsing the order of the standard form
one can rewrite the equation in matrix form:
Further, this representation extends to systems of linear equations.
becomes
Since this extends easily to higher dimensions, it is a common representation in linear algebra, and in computer programming. There are named methods for solving simultaneous linear equations like Gauss-Jordan which can be expressed as matrix elementary row operations.
Parametric formand Two simultaneous equations in terms of a variable parameter t, with slope m = V / T, x-intercept (VU−WT) / V and y-intercept (WT−VU) / T.This can also be related to the two-point form, where T = p−h, U = h, V = q−k, and W = k: and In this case t varies from 0 at point (h,k) to 1 at point (p,q), with values of t between 0 and 1 providing interpolation and other values of t providing extrapolation. Polar formwhere m is the slope of the line and b is the y-intercept. When θ = 0 the graph will be undefined. The equation can be rewritten to eliminate discontinuities: Normal formThe normal segment for a given line is defined to be the line segment drawn from the origin perpendicular to the line. This segment joins the origin with the closest point on the line to the origin. The normal form of the equation of a straight line is given by: where θ is the angle of inclination of the normal segment, and p is the length of the normal segment. The normal form can be derived from the general form by dividing all of the coefficients byThis form is also called the Hesse standard form,[citation needed] after the German mathematician Ludwig Otto Hesse.shawal is the bestWhich layer is responsible for character-encoding schemes such as ASCII?
I assume you're talking about portion of the OSI model that handles character-encoding such as ASCII. It is the Presentation Layer of the OSI model.
How does computer help or society?
It depends on what decade you want to know about. When electronic computers were first being built, they were useful in that could do long, complex calculations in a short amount of time. This was very critical to space travel, for example. We would not have walked on the moon without computers. In modern times, there are countless different ways computers help society, but in my own opinion, the most useful and socially helpful thing they can do is to run simulations. Lots of new inventions are tested in computer simulations. This is called Computer Assisted Design. Buildings, cars, military weapons, all kinds of things are tested in computer simulations before being built. Just about every car made in the last few years were made using Computer Assisted Design.
