What Methods are used for electronic communication channels?

Fax - Fax uses the public telephone system as a way of delivering paper documents from one place to another, for situations where a hard copy isn't essential. This can be used for business to business communication.

Email - E-mail has become the primary means for delivering short text messages within organisations that are networked. E-mail between organisations is has become more common and this method is increasingly take the place of fax, particularly as whole documents can be sent as e-mail attachments. E-mail provides many cost advantages when compared with the use of paper or the telephone. This can be used for staff to staff, staff to customer and customer to staff communication.

Telephone/ Mobiles - Phones are universal and, with the advent of voice mail and mobile phones, it is now possible to reach people practically anytime, anywhere. This can be used for staff to staff communication.

Video Conferencing - Video conferencing uses phone lines to transmit video as well as sound, between two or more groups. Because cameras, microphones, audio playback and special software are required, video conferencing is used only infrequently and on specially-provided workstations. However, as networks become more powerful and the machinery becomes less expensive, it is possible that this will eventually be available to everyone. This can be used for staff to staff communication.

Intranet - An intranet uses the same technology as the Internet, but operates within the confines of a single organisation. Normally an intranet is used to deliver text and images. Information is much less expensive to distribute and maintain with an intranet than with paper copies. This can be used for staff to staff communication.

Who made ps4?

Ps4 or the play station 4 is a gaming console manufactured and designed by a Japanese company named SONY it is debated to be the best gaming console....

Can my playstation 3 slim cech 2501a Blu-ray drive work on a different cech 2501a motherboard. do i have to remarry it or is it just plug and play?

To the best of my knowledge these blu ray drives on the czech-2501a systems are plug and play as long as you have just four ribbon cables to connect.... however some systems have a chip board on the bottom of them..in which case that is the blu ray control board and its married to your ps3 mother board. However its still an easy fix as you just swap the Control Board from your original blu ray to the new blu ray drive and it should solve your issue.

Is siri a boy or a girl?

A girl ask Siri you will be surprised by the answer

Does the electronic ignition system use contact points?

No it doesn't. A magnetic pick-up or a position sensor tells the electronics when to produce the spark.

What is the direction of information flow on the data bus?

The flow of information on the data bus is bi-directional. When status pin S1 is high, it is a read from IO or memory towards the CPU; when S1 is low, it is a write. S1 is present on the 8085. On the 8086/8088 it is inverted and combined with DT and called DT/R-

Can you access your electronic medical record on your own?

There are types of I.D cards available so that you can access your own medical records. This can be helpful in the event of an emergency so that doctors and hospital personnel can know your health immediately.

What is an electronic device that processes data?

There are different types of processing devices. Processing devices with computers are devices that transform computer data into a usable format for the user. The devices can perform many different functions such as store data, analyze and sort data, record and display data, and calculate and summarize data. The device processes the input into useful output. The central processing unit in a computer processes and stores the data inputted into the computer. It works with the motherboard and the random access memory. Other types include microprocessors and multi-core processors.

What is the lead selector switch on a ECG machine?

Eeach electrode connected to the patient is attached to the lead selector of ECG.This will determine which electrodes are necessary for a particular lead and will connect them to the remainder of the circuit. It can be controlled by the operator or by the microcomputer of the electrocardiograph. It selects one or more leads to be recorded.

What do the three circles on a g shock mean?

the circle on the far right with the numbers around it mean the seconds and the middle circle means the minutes and the left on means the hours

Is square wave inverter harmful to electronic devices?

Depends on the device. For instance almost all laptop power supplies use a international (aka universal) switch mode power supply. They don't care about modified sine wave output at all!

Almost all low-cost inverters use a step-wave output that approximates a RMS sine wave (like wall voltage). This is a double square wave with a gap between the negative going and positive going squares. The inverter companies call this "modified sine" which is kind of a misnomer used as a marketing term. The more expensive inverters use a high-frequency Class-D amplifier to produce a more accurate approximation of a sine wave. It's usually not "pure", as it has some amount of harmonic distortion, but for marketing reasons they try to distinguish their product from the "modified-sine" by using the "pure sine" misnomer.

The front end of all switch-mode power supplies rectify the incoming AC into DC as a first step in conversion. Step wave rectifies just as well as a normal sine wave! The ONLY reason to run "pure sine" inverters is if you are running sensitive audio gear with linear power supplies, as step-wave will induce a buzzing noise in the audio signals whereas the smoother approximation will not.

Don't believe the hype that the "pure sine" inverter companies promote, it simply isn't true. The only things that are dangerous to run on step-wave are things with triac devices or capacitor-based power supplies. This includes things like Dewalt power tool chargers, light dimmers, etc. If it's extremely light (feels like there's nothing in it), and/or it has a 120V rating only, then it's probably not safe for step-wave use. Dewalt chargers have been known to fail and overheat on step-wave!

If your power supply has a wide input voltage, such as almost all laptop supplies (100-240v), it is a universal switch mode supply and therefore safe. This includes most small electronics chargers, like for phones, iPods and cameras. If the voltage requirement reads only 120V and it's NOT a heavy "wall-wart" type supply, it's probably not safe. Check your nameplates!

If your device has sound such as a TV or Stereo and it emits a buzzing sound out of it's speaker when you run it on step-wave, then that's not harmful, but is an annoying side-effect. You can buy the more expensive "pure-sine" model if this is undesirable.

What is mean by resolution 1920x1080?

Resolution is the number of pixels that make up the picture on your t.v. or computer screen. 1920x1080 means that there are 1,920 individual colored points of light across your screen's width and 1,080 across its height for a total of 2,073,600 pixels. Each pixel is capable of changing color as needed to display images on your screen. The higher the screen's resolution, the clearer the images it can display.

What are the uses of cables?

Different types of cables are used for different purposes:

  1. Power cables are used for the transmission of electrical power.
  2. Chain cables are used in vehicles like motorbikes.
  3. Optical fibers are used to send signals in the form of electric current over long distances.
  4. Cables are used in the movement of elevators.
  5. Cables such as ropes are used for hauling, most commonly used in ships.
  6. Such cables are designed to connect medical and laboratory instruments and equipment. They transmit power and/or data and usually have an abrasion-resistant jacket that provides relatively low surface friction and mechanical durability.
