Telephone History

Tuesday, January 31st, 2012

With six billion people on the planet today using some form of telephone, it is probably the most widely used piece of technology in the world.

The invention of the telephone is often attributed to Alexander Graham Bell, who in 1876 was the first to obtain a patent on a sound transmitting “apparatus.” But truth be told, many other inventors had been working on similar technologies ever since the 1830’s.

The same year that Bell got his patent on the telephone, a Hungarian engineer named Tivadar Pusks created the telephone switchboard, an essential component for the creation of a telephone network.

From the 1870’s until the 1890’s, telephones were sold in pairs that would be connected over a distance for personal or business use, e.g. between a factory and the residence of its owner.

The creation of a telephone network through the use of switchboards began in Lexington, Massachusetts, in 1894. The operators were almost exclusively women, and for the next half-century, this was how all long-distance phone calls in the United States were relayed.

The ability to place direct long-distance phone calls was introduced only in 1951, when eleven cities across the U.S. were assigned “area codes.” Those cities were: Boston (617), Chicago (312), Cleveland (216), Detroit (313), Milwaukee (414), Oakland (415), Philadelphia (215), Pittsburgh (412), Providence (401), Sacramento (916), and San Francisco (318).

Since this introduction of area codes and automatic long-distance calling in the 1950’s, technical advances were made and signal transmission became digitized (as opposed to analogue) but the way we used telephones remained pretty much unchanged for four decades. Only in the 1990’s did VoIP get introduced, and Mobile Phones experience their boom.

Voice over Internet Protocol (VoIP)

The most recently invented major telephone technology is called VoIP, which stands for “Voice over Internet Protocol.” VoIP was invented in 1994 by Alon Cohen and Lior Haramaty. However, the technology could not be put to practical use until the first software was released by VocalTec in 1995.

Dozens of companies today offer VoIP telephone services at low cost compared to traditional landlines; two of the most successful being Vonage and Skype.

While extraordinarily price competitive, three disadvantages commonly mentioned with VoIP phone services are, 1) You cannot make emergency calls (911) through your VoIP service, 2) Your number will be unlisted, which may make you more difficult to find, 3) Your phone will not function when there’s a power outage.

Mobile Phones

Mobile phones experienced an explosion in popularity in the 1990’s, driven by lower cost and expanded networks. However, it may surprise you to know that the first successful mobile phone took place in 1946, from a car in St Louis, Missouri.

Ten years later, the first automatic car phone was introduced in Sweden. That contraption, constructed with vacuum tubes and relays, weighed close to 90 lbs.

Even though the technology transmit phone calls wirelessly is old, the use of cell phones did not take off in earnest until the 1990’s. At the end of the 1980’s, only one in seventy Americans use some kind of mobile phone, and many of those were the kind installed into automobiles. Ten years later, the number of American mobile phone users had jumped to one in three. Take another leap to the year 2011, and the number of cell phone subscriptions surpassed the population; which means that on average, every American now uses a mobile phone.

Worldwide today, there are 5.9 billion mobile phone subscribers out of a world population of 7 billion. Compare that to a mere one and a quarter billion landline telephones. The mobile phone revolution is complete.

China IPad Clone Wars 2010

Saturday, October 16th, 2010

Either you lead or follow and Chinese manufacturing houses have been chasing Apple’s designs for years. The iPad is just their latest victim. You can’t blame them, really. It’s the hottest device since the rotary phone.

A steady stream of China iPad Clone has been flowed into market for months since iPad was released. Here is Top 7 China iPad beginning with three well-powered iPad knockoffs.

It boasts Android 2.1 operating system, 10.1-inch touch screen, ARM Cortex-A8 1GHz processor, 512MB DDR2 memory. Seems to be a good iPad alternative, right?

[I:http://www.uniquearticlewizard.com/extras/pics/vostrostoneimage8.jpg]M1touch – You might have ever seen something like this China iPad somewhere? This iPhone-styled tablet PC packs 10.2-inch capacitive multi-touch screen, Windows 7 Ultimate system, Intel Atom N450 1.66GHz processor, 2GB of DDR2 RAM, Wi-Fi and optional 3G module, 1.3MP web camera and three USB2.0 interfaces.

iPed – The iPed is the first China iPad to hit the scene. It packs the usual Android build into a casing that looks a lot like the real thing. It even ships in a box that’s nearly a photocopy of the iPad’s retail box besides the iPod label is replaced with iPed. Sneaky.

Meizu Mbook – Meizu Mbook is rolled out by the manufacturer Meizu that became very known in China due to its successful copy of Apple iPhone.

Ink Refills For The Smart

Thursday, September 9th, 2010

Who says you have to spend more money than you have to when you’re printing out hundreds of pages regularly? Brand new cartridges are really costly to buy even the cheapest ones in the market. For a fraction of the price of the new one, you can extend the life of your cartridge with refills. One or two refills are recommended. You don’t have to be throwing out too many cartridges that will cause a lot of garbage anyway. You can buy ink refills online pretty easily so why pay too much for a cartridge when these would work just the same and save you a lot more money in the end? You can opt for this cheaper means but you’ve got to know what you’re doing so you don’t break your printer.

Get refill kits that are compatible with the printer model you’re using. You can’t just swap refills with a totally incompatible cartridge. That would just compromise the quality of your printouts. Printer ink would vary in formula depending on the brand and model and a couple of other things that aren’t worth looking into.

Don’t let your cartridge run empty. I’ve made this mistake a few of times and it just totally messed up the printer. You’d have to run the printer maintenance program a hundred times every time you print something out just so it would temporarily correct the damage done to it by a clogged cartridge outlet.

All ink refill kits come with instructions on how to properly refill your cartridge so do follow it instead of doing guesswork. You will be running the risk of doing damage to your cartridge or your printer head. In case you’ve made this mistake, don’t make things worse by running a few prints. When it’s damaged, contain it within the cartridge so it doesn’t get passed on to your printer. Get a new cartridge in this case.

Don’t make the mistake of putting the wrong colors in the wrong cartridges. That would obviously give very different results in your printouts. Once you’ve done it, you’d have to replace the cartridge. You also want to keep your work area clean so just like painting the walls, cover enough space with a lot of papers or some cloth so your furniture won’t get stained.

What happens now when you get some ink on your hands? They don’t come off with soap alone. You will have to wash it off with a mild bleach solution mixed with water and then wash the bleach off with the soap.

Take advantage of the huge savings to be had in using ink refills. It’s fairly simple how to refill cartridges and it will benefit you in the long run.

Which Printing Device Is The Most Suitable For One’s Printing Requirements

Tuesday, September 7th, 2010

Printers may be purchased relatively low-priced nowadays, based on one’s requirements. If you only require something compact for producing documents in the home, then one of the compact, less expensive printers might be all that you require. If, however, you have a business or company, your needs might be diverse and so you will most likely require one of the bigger, higher priced kind of printers.

You may additionally need to have extras such as more printer trays. They are practical if you have to print on various size sheafs of copy paper or when you have an organization that does a large amount of printing. Should it be simply for home use, then it would be silly to purchase these additional features.

Generally if the computer printer is likely to get used by a lot of employees, you’ll need to acquire a computer printer that has the capacity of being networked. This prevents you needing to acquire a computer printer for every single work station. Their computers can easily be networked into the main computer printer, which saves a bunch of money and space on workstations – not having them cluttered up with a computer printers. Your employees can easily wander over to the principal computer printer to get hold of their printed pages.

For those who only print text, then there’s no need to have to acquire a color computer printers. Even though it is nice to get a color printing device in the event you now and again want to print an item in color, the drawback with this is that if you won’t print in color often, the color cartridges are inclined to dry out. Then when you do wish to print something in color, you will need to change the color cartridges.

And it may prove costly if you’ve got to dash off and obtain replacement color ink cartridges every few months. This does not matter a great deal if you use color often – at the least you are getting your money’s worth; it may just get a little costly once the cartridges just dry up and require to be changed, simply because they haven’t been made use of for a couple of months.
