Chat and instant messaging:sms


  
sms
SMS text messaging is the most widely used data application in the world, with 3.6 billion active users, or 78% of all mobile phone subscribers.
SMS works on a store-and-forward basis. Instead of being sent directly to the recipient, SMS messages travel through several important nodes befor
e reaching the recipient (skip this part if you find it boring; there's more good stuff below).


How does sms work?
  1. The SMS message is submitted to your wireless service provider's SMS Center.
  2. After the message is processed internally, the SMS Center sends a request to the Home Location Register (HLR) and receives the routing information for the recipient.
  3. The SMS Center sends the message to the Mobile Switching Center (MSC).
  4. The MSC collects the recipient's information from the Visitor Location Register (VLR) and, sometimes, proceeds with an authentication operation.
  5. The MSC forwards the message to a Mobile Server.
  6. If the recipient has a Treo or VisorPhone, the SMS is placed on the SIM card until the handheld picks up the message and transfers it to the internal memory on the unit.
    This is how Treos and VisorPhones can store hundreds of SMS messages, unlike ordinary GSM mobile phones that store only a few SMS messages.
    Treo or VisorPhone owners may encounter the error message "Your SIM contains at least one SMS message. Do you want to move the message to your Visor?" See the relatd SMS article in our knowledgebase for details.
  7. The MSC returns the outcome of the Forward Short operation to the SMS Center.
  8. The SMS Center reports delivery status of the short message back to the sender.

Working styles tool man


Working styles tool man


ICT is transforming the way people live in virtually every area of their lives. ICT has affected work styles positively in that it has helped manage and process information faster, conveniently and cheaply. ICT has helped reduce company running costs by reducing paper work, effective time management through better means of communication and faster turn around times in regard to output. This has resulted in higher productivity and effective management styles. In the working population ICT has come as custom to major cooperation's. Shop assistants use EPOS and EFTPOS(payment systems) and stock control systems. EPOS- Electronic point of sale is a computerized till connected to a price look up database, and possibly to the live stock databases. EFTPOS-  Electronic funds transfer at point of sale. A system that allows debit cards to be used to pay for goods. The funds are transferred automatically by the machine at the till from the buyer's bank account to the seller's. Car mechanics use computerized analysis equipment to diagnose many of the faults that they are presented with. Even teachers are expected to use PCs network interactive whiteboards and wide range of software.






 PDA


personal digital assistant (PDA) is a mobile device that functions as a personal information manager. PDAs are largely considered obsolete with the widespread adoption of smartphones.

Features 
 PDA has an electronic visual display, allowing it to include a web browser, all current models also have audio capabilities enabling use as     a portable media player, and also enabling most of them to be used as mobile phones.  Most PDAs employ touchscreen technology.PDA use can access your emails via the internet using WiFi. Most PDAs can synchronize their data with applications on a user's computer. This allows the user to update contact, schedule, or other information on their computer.





 GPS


The Global Positioning System (GPS) is a space-based satellite navigation system that tells you the location and time information in all weather, anywhere on or near the Earth, where there is an unobstructed line of sight to four or more GPS satellites. It is freely accessible to anyone with a GPS receiver. GPS provides specially coded satellite signals that can be processed in a GPS receiver, enabling the receiver to compute position, velocity and time.


 Laptop


Laptops were made for increased convenience to travelling business man or casual surfers. The Laptop is lightweight and portable unlike a desktop computer; however it has the same characteristics. The laptop computer has a built in touch pad so that it can be operated without a mouse. Furthermore it has the processor, memory, operating system, hard drive, and monitor. Laptops are unique from other computers, in that it is difficult to exchange parts between laptops and desktops, and replacement parts for laptops can be pricier than most. However, this disadvantage is greatly out measured by the speed, connectivity, and economical value that laptops possess over standard computer models. 

Disadvantages of having the latest technology
However there are several disadvantages  for him in employing a lot of ICT. Firstly with any new technology at one point in time there will big a possibility that it will break or have a fault because companies build their products in obsolete, so you will buy more of their products, therefore getting more profit. This can be costly replacing or fixing these technology. Another factor could be that the constant use of the internet that you could catch a virus or a Trojan horse. This could damage your computer by corrupting the files, therefore the files wouldn't work and it would be hard for John to work efficient.

4th generation (4G) technology

What is 4g?

In telecommunications, 4g is the fourth generation of mobile technology. A 4g system provides mobile ultra broadband internet access. Here is a useful article that i gathered my information from.
. http://www.pluggedin.co.uk/article/4g-mob. ile-technology-what-you-need-to-know-and-how-to-get-it
















 Whats the difference between 4G and 3G?


4g uses the tc/ip protocools that power the internet.4G system provides mobile ultra-broadband Internet access.  Recently Android and Windows-enabled mobile phone devices have fallen in the 4G category. According to IMT-A, 4G mobile devices must be IP-based and able to provide data speeds of up to 100 Megabits per second (Mbps) when the device is being used while moving and up to 1 Gigabit per second (Gbps) when stationary. 3G guarantees minimum speed of 144 KPS and up to 400 KPS, however in this modern society that is not fast enough. 4g should guarantee no buffering whilst watching videos and instant downloading of music and HD movies. Offcom says it will need to reach 98% of the population and 95% of the country by the end of 2017.

social networking and communication



Social Networking


Social Networking has grown massively in a very short space of time. The first site were set up in 1995 called www.classmate.co.uk.  Also one of the first social networks was friend united in UK in 2000.This area has grown with the development of Facebook, Twitter, Linkedin, MySpace, Google Plus+ etc. The most popular social network sites is Facebook, twitter and Google plus.


Social networks also can be an essential tool for e-commerce as most business use the internet to sell goods for their business. Clever businessman should use social networking as an opportunity to market their business and can send out large batches of messages to people in one hit - this is achieved much more easily sending to members of a group than sending from your individual profile

Social networking allows me to keep in touch with family and friends that live far away by sharing updates, photos, videos, and messages. Family members and friends can stay connected even if they live across the country or the world.
Also a social networking site can be a good way to make connections with people with similar interests and goals. I have personally made new friends on Social network sites by sharing interests that i have in fitness where we have discussed different fitness programs.I find that it can be a way to connect with people that I  may not have had the opportunity to before.
Most importantly, social networking sites offers people the opportunity to create a positive self-image. The profiles gives you a chance to create the image of themselves that you want people to see by putting you best qualities on there. This shows that you care about you reputation and what people think about you.

However a danger to being on a social networking site is that scammers use social networking sites to trick people into downloading malware. A common tactic is to use social engineering. Social engineering plays on human nature to get results. For example you may have a friend send you a link to a video and the link will tell you have to download a type of software to view it. This is the virus that can harm your computer.
Also identity theft can be easily done by gathering information on people’s wall and is very addictive and could be procrastination if you need to do stuff.

Facebook


Facebook is a social networking service launched in February 2004, owned and operated by Facebook, Inc. As of September 2012, Facebook has over one billion active users, more than half of them using Facebook on a mobile device. 
 For a small  business it is important to expose your business, facebook can be stepping stone to do this. It is also a free way to market your business, so If you make use of not only the Pages application, but also many of the other applications, you will find great, user-friendly tools to market your services and products and promote what you do. Facebook offers you the possibility to create ads and target them to a specific age group, gender and location. You can also track your ad’s performance



Here is step by step guide to how to set up your 
Facebook page for a business. 


Choose a category and a Page name that represents your business.
Pick a logo or another image that people associate with your business to use as a profile picture.
Write a short paragraph about your business so people understand what you do.
Set a memorable web address for your          Page that you can use on marketing material to promote your presence on Facebook.

The digital divide

The digital divide

Ict has transformed the way we lived. It has brought enormous, educational, social and economic benefits to those who have it. In Africa it is estimated that in July 2005 less than 1.8 percent of the population used internet, in contrast 68 percent in north america.



This graph shows that the developing country internet usage is slower than western society this could be because of economic factors.  Rich nations can bridge physical obstacles, and for examples take electricity, takes electricity across the mountains and ravine, whereas this may be low priority of for poorer nations. Furthermore economic factors alone do not determine the extent of the digital divide. If there is no steady electricity supply it is not easy to use the digital technologies that are so reliant on. 


This is a map showing internet usage percentage in the united kingdom. It shows you that the south of England have a higher percentage of internet usage, whereas the north have a lower percentage. This could be because the north of England is not as rich as the south. 

Why is there a digital divide?

Economic prosperity is a major factor if a country has a modern technologies in society. A poorer country will be more concerned than survival rather than modern technologies. A developed economy can afford to devote energy and resources to research new developments in technology and has the affluent customers to purchase the new digital economies. On the other hand a poor economy has a poor technological infrastructure, which makes it difficult for them to improve their technology. Furthermore rich countries can bridge physical barriers, for example takes electricity across mountains and ravine, whereas this may not be a priority for a less economic developed country.
