big advantage of parallel transmission is the factor of speed. All else being equal, parallel transmission can increase the transfer speed by a factor of n over a serial transmission. But there is also a very significant disadvantage of parallel transmission. And that is the factor of cost. It can be proved from the fact that the parallel transmission requires 'n'

Att is a Internet , Cable , and Home phone company. There is no 1 thing that att does

Answering the phone when all others are occupied.

You should review the job description of the position for which you are applying. Think about how what the company needs parallels with your skills. Those will be the areas in which you will be able to make contributions to the company.

It had been used to communicates

Morse Code allowed letters, numbers, and punctuation to be transmitted as long and short 'clicks' over railroad telegraph lines to quickly communicate information before the telephone was invented.

By RogerTango:

Also, the tone of a CW signal is much easier to identify with weak signals or a lot of interference. A Morse code tone only needs about 50 hertz of audio bandwith, a human voice requires about 1,000 hertz to be understandable. Morse Code is also a much more efficient mode of transmitting on radio when using limited RF power. HTH, Andrew

The major disadvantage of fiber optic versus metal cable is that it is difficult to make connections to fiber optic cable. Single-mode optical cable (the type used for communications) has a core as fine as a human hair (although the entire fiber is thicker). When making splices, the fiber cores must be perfectly aligned. Also, the ends of the optical fiber must be highly polished to allow light to pass with little loss. There is also the problem of converting back and forth from a light signal to an electrical signal. However, the advantages of fiber-optics far outweigh the problems. One single mode fiber can replace a metal cable that is thousands of times larger and heavier. Multi-mode optical cable has a larger diameter and can be used to carry signal over short distances.

1. You wrote your message on a telegraph form.
2. You handed the telegraph form to the clerk at your local telegraph office.
3. The clerk would count the words of the message and tell you how much it would cost.
4. You would pay the clerk.
5. The clerk would put your telegraph form in the stack of outgoing telegrams.
6. The telegraph operator at your local telegraph office would send the telegrams on the telegraph forms in the stack of outgoing telegrams using the telegraph key.
7. The telegraph operator at the recipient's local telegraph office would listen to the telegraph sounder and write the telegrams down on telegraph forms and put them in the stack of incoming telegrams.
8. Telegraph delivery boys/men would take the telegraph forms in the stack of incoming telegrams and go around town delivering them to the recipients.

Morse Code provides a letter-based method of communication by means of any type of signal that can be switched on and off ... light, sound, etc. As such, it can accomodate messages in any language that uses the familiar Roman (English) alphabet. While using the simplest possible transmitting and receiving equipment, it is highly immune to noise, and can succeed over very noisy 'channels'.

Many DSL connections are broadband, but not all broadband is DSL. Broadband is a type of telecommunication that uses multiple data channels to send large volumes of information. The term broadband is an abbreviation of "broad bandwidth." Broadband Internet services such as DSL and cable are considered to be high-bandwidth connections. Bandwidth is the amount of data that can be sent along a given channel per second.

There are three popular types of broadband Internet service: satellite, DSL and cable. Satellite Internet uses a satellite that's in orbit around the Earth to facilitate the transfer of data. DSL transfers data along unused bandwidth on ordinary telephone cable. Cable Internet uses a coaxial television cable to provide Internet service.

The slowest of all broadband services is DSL. It is also the least expensive service. It offers speeds up to 6 megabits per second (Mbps). Cable is faster, but it's less reliable and more expensive. Although cable Internet service providers often advertise download speeds up to 30 Mbps, cable users rarely achieve these speeds. Satellite is the most expensive of all commonly used broadband Internet services. Satellite speeds can range anywhere between 1 and 3 Mbps. The Federal Communications Commission now defines a broadband connection as having speeds of 768 Kbps. Therefore, not all DSL connections are considered broadband

The pioneer for this is Nikola Tesla, who holds the patent for this invention. It was he who laid down the fundamental principles of wireless data transmission for the first time in his lectures.

Yes, you can connect a PC wirelessly to a DSL connection. You will need a wireless access point/router and connect that to the DSL modem via USB or ethernet. Configure your PC to attach to the wireless access point/router using the wireless (802-11a,b,g) or eithernet.

Networking and telecommunications are responsible for keeping computer network systems running and secure

The emergency code "SOS" was chosen not because it means anything, but because its Morse Code is very simple to remember and transmit: dot dot dot dash dash dash dot dot dot. This combination of letters was established in 1906 by the International Radiotelegraphic Convention in Berlin. It is still used as an international distress signal, especially by ships and aircraft. Many people have made up acronyms for SOS, such as "Save Our Souls," "Save Our Ship", "Sink Or Swim", "Send Out Sailors", "Save Our Skins", and "Send Out Someone", but these were invented after the fact. SOS is also the theme of the Song "Message in a Bottle" by The Police.

A DSL (Digital Subscriber Line) is a telephone line that carries digital data from end to end, and can be leased from the telephone company for individual use. Telephone technology. Broadband refers to a networking technology that carries more than one type of signal such as DSL and telephone.

The main function of a phone is to communicate with people, but a phone has multifarious functions. The phone allows people to do many things such as text, find directions, Call, go on the internet, take pictures, have access to the internet, go online as in social networks.

The acquisition of an ability in Morse Code is a significant accomplishment for most people, just as any other representational language. Animals don't use it.

All over the internet are international calling cards, but the cheapest advertised prices comes from TEL3, BixDial.com, Comfi.com, Zaptel.com. The rates they advertise from is as low as 1 cent.

For AT&T: Send it to: your number with the area code @txt.att.net. If your sending pictures, music, or videos, it's @mms.att.net. If your cell number is (123)-456-7890, sent the email to 1234567890@txt.att.net or 1234567890@mms.att.net

Some guy who wanted a better calling system.
