What do telecommunications workers do?
A telecommunication mechanician is a trade in the telecoms industry. The term "mechnician" is used for historical reasons and relates back to the days of mechanical exchanges, where the term "mechanician" was more appropriate than "technician".
The telecommunication mechanician trade relates to many aspects of the telecoms industry including the installation, commissioning and maintaining of telecoms equipment like PABX, Exchanges, transmission equipment, telephony devices etc.
At one point, Cingular bought out AT&T Wireless. Then it became AT&T again since it was the stronger name.
A DSL Internet connection is faster than a satellite Internet connection?
It all really depends on which phone company you have that is offering you the DSL. To my knowledge, the fastest satellite Internet connection is 12mBit/s, which is approximately 1 - 1.5 mByte/s. DSL is usually anywhere from 1.5mBit/s to 10mBit/sec. As said before, it is suggested that you check out the website of your local phone company to determine what packages they offer.
What would happen to the world if Morse code wasn't invented?
Who knows? Ships everywhere would be doomed! Morse code required a human ear to interpret the received code since a lot of analysis was needed by he human brain in order to decipher the code.
Machines reading Morse code struggled until advanced electronics could cope with the varying length of each character. The telegraphic 5 unit Baudot code used in telegrams and telexes standardised the code so that every letter and number consisted of an equal length.This simplified the decoding to a point where relays and mechanisms could decode and print the received signal.
To answer your question ? They would have come up with something better. It triumphed because it was first on the scene.
Who developed a code that would communicate messages using a telegraph?
Samuel Morse invented the telegraph and the code that the telegraph used (Morse code).
In which year was telephone discovered?
Alexander Graham Bell invented the telephone in 1876, though he died in 1922. Everyone loved him and we're still using his invention today!
What are the major differences between cable modems and DSL modems?
Cable modem connects through fibre optic DLS through phone line. Cable boasts faster speed than DSL Internet in theory. However, cable does not always deliver on the promise in everyday practical use. Cable modem services can slow down significantly if many people in your neighborhood access the Internet simultaenously. Both cable modem and DSL performance vary from one minute to the next depending on the pattern of use and traffic congestion on the Internet. DSL and cable Internet providers often implement so-called "speed caps" that limit the bandwidth of their services. Some home networks cannot match the speed of the Internet connection, lowering your performance
Can you switch a Samsung phone from ATT to Verizon Wireless?
No, AT&T uses GSM, and Verizon uses CDMA. The two technologies are not compatible.
yes,
every family should have one or somesort of machine to communicate each other with.
Answer
Telephone is the life blood of a business. The right kind of the phone system such as the Virtual PBX system have the ability to unify home and office communication devices . So, the functions and features of telephone is very necessary to run the daily business activities.
Where in North America is area code 205?
North American area code +1 256 is in northern Alabama, including Huntsville, Decatur, and other towns.
International country code +256 is Uganda.
(The plus sign means "insert your international access prefix here." From a GSM mobile phone, you can enter the number in full international format, starting with the plus sign. The most common prefix is 00, but North America (USA, Canada, etc.) uses 011, and many other countries use different prefixes.)
Telephone system developments?
Key system is the basic and traditional phone system we have. Calls are routed through PSTN to establish calls. The newest development which are the PBX and VOIP PBX uses the hi speed broadband
Internet connection to carry over voice or analog signals. It uses gateways to convert analog signal into digital signal.
The terms SDU as well as MDU are used in the context of Broadband connections, and more specifically in the context of Fiber Optics networks.
SDU stands for Single Dwelling Unit, and MDU stands for Multi Dwelling Unit.
When analysing or designing Fiber Optics networks of a technology FTTx (Fiber-To-The-x, e.g. FTTH: Fiber-To-The-Home, FTTB: Fiber-To-The-Building etc.) one needs to know where the fiber optic cable ends: at the basement of a building or inside a house or appartment. The cabling and equipment requirements to connect a single home (SDU) are different than those used to connect all the appartments in a multi-level building (MDU). Hence the need for distinction between the dwelling types of the end users of fiber optic connections.
PDU stands for Power Distribution Unit. This is used inside data centers.
-------------------------Advantages-----------------------------------------------------Disadvantages-------------
- Useful if radio or other technical communicants are compromised.
- No expensive equipment, just flags and a pair of binoculars
- Only trained individuals can understand the message making secure.
- It is cheap to set up the equipment needed to work it.
- It is universally understood by operators in all countries.
- Messages can be sent in Morse code in three basic forms; signaling involving the transmission of pressure, the transmission of light or radio waves.
- People need to be trained to operate the equipment and to use and translate it.
- It requires line of sight which can be hard to find in bad weathers.
- It is time consuming to send, receive and translate the messages.
- Morse code is slow and cumbersome compared with modern communication.
- You cannot be 100% sure that the recipient will understand Morse code.
- It is easily to misread the message as the difference between the length of signals identifying letters and words is very small.
- It is slow to use compared to talking over a telephone.

A periodic signal has two major characteristics: frequency and amplitude. Frequency is the number of times the periodic signal occurs in a set time, and the amplitude refers to how strong the signal is.
What are the advantages of Satellite Internet over DSL Internet?
the information travels faster , dsl travels in a line and depending on where your transfer station is for dsl so yes satellite is faster goes direct into your cable. The main advantage that satellite Internet service has over DSL is that satellite Internet is available virtually anywhere in the US even in rural areas where DSL and Cable don't reach. Generally, satellite Internet service beats cable or DSL Internet when DSL or cable Internet is NOT AN OPTION. Cable or DSL access is almost always cheaper (less expensive) than satellite Internet, but not always faster.
Morse code has improved communication in a lot of ways. Here are just several of the benefits of Morse code out of a whole lot of others:
- In aviation pilots use radio navigation aids. They usually emit a short set of station identification letters in Morse code in order to ensure that the stations they're using is in good service.
- The International Morse code is a favourite with amateur radio operators, as they can quickly key a transmitter on and off (also referred to as 'continous wave' or 'CW').
- Morse code can be used as a signal for help (SOS).
- Morse code has also helped many people with disabilities to communicate.
What are the benefits and limitations of the relational database model for business applications?
In theory, relational databases (RDBMS) probably have no "hard" limits. In practice, existing products tend not to perform very well at certain kinds of processing. RDBMS are optimized to perform many different kinds of queries on the same data fairly well. This keeps them flexible, able to handle unanticipated uses.
But some applications require very specific kinds of queries and need these specific queries to be as fast as possible (or at least have well-known response characteristics). Sometimes niche or custom databases perform sufficiently better than existing RDBMS that it warrants such solutions.
Some also suggest that RDBMS don't fit object-oriented applications very well. This is a contentious topic with no easy answer. RDBMS and object-centric designs tend to use conflicting philosophies such that mixing and coordinating them can be difficult and expensive. Some commercial products claim to bridge the gap.

What was the second telephone invented?
The first and second telephones were made at the same time becasue, unless you had the second one, you could not demonstrate that the first one worked.
