Nowadays, everybody has a mobile phone. Whether they’re on a contract or a pay as you go tariff, the mobile phone has become an essential item for many people. this article will be taking a look at the the mobile phone’s history – as well as its future – in order to find out more about the now essential telecommunications device.
Mobile phones started life as the two way radio, which was also called mobile rigs. these were installed in vehicles such as minicabs, police cars and ambulances, but were not strictly mobile phones as they were not normally connected to the telephone network. while the very first mobile phones were installed permanently in vehicles, later versions such as the transportables, also called bag phones, could also be carried, and can be used as either portable or as mobile two-way radios.
The first generation of mobile phones are often called 1G. These mobile phones are the analog devices that were introduced in the eighties & continued until being replaced by 2G mobile phones, which ran on digital networks. in fact, even though 1G & 2G systems use digital signals to connect the radio towers to the rest of the telephone network, the voice itself during a phone call encoded to digital signals in 2g while voices on 1G phones aren’t.
Second generation, also called 2-g, mobile telephones were introduced in the nineties. 2-g phone systems were characterised by their use of digital transmission and the introduction of advanced and fast phone to network signalling.
The birth of 2-g systems saw telephones move from friendly 1g telephones to little handheld items, which were much more portable. this change was possible through technological developments including more advanced batteries and energy saving electronics.
The second generation mobile telephones had severaladvantages over 1g items. These included text messaging, which became possible on gsm networks initially and eventually on all digital networks. the earliest machine-sent message was sent in 1991 in the uk. the earliest person to person sms text message was sent in 1993 in finland. sms text messaging soon became the preferred method of communication and the public now prefer sending text messages to placing voice calls.
3-g is the term applied to the third generation of mobile phone standards & technology. 3g follows 2g mobile phone technology.
The birth of 3-g technologies allow network operators for instance Vodafone give their users a larger range of more advanced services. These include video calls& wireless internet.
Even though 3-g was successfully introduced throughout the world, issues have been raised by both 3-g providers & users, comprising of costly phones. in addition to this, there’s numerous differences in the licensing terms.
Ever since the launch of 3-g mobile phone technology. people have been talking about 4g. 4g technology will signify the future of mobile telephones, creating the most sophisticated handsets and best services yet. in actual fact, one of the next services to be developed is thought to be live streaming of radio and tv shows to 3-g handsets is and shops including real and disney recently announcing that they’ll be offering services like these.
In conclusion, even though the history of mobile phones they have come a long way in the past few years, it also indicates that they’ll go even further still.

Upstairs Solutions LTC announces the expansion of its online learning materials specifically developed for senior care staff in Assisted Living (AL) communities. The Upstairs Solutions library is the most robust in the industry and features unique content, language, examples, and visuals specific to the Assisted Living sector.
Assisted Living facilities train staff not only to provide best practices in care, but also to assist with regulatory compliance management. According to Maria Schmidt, RN, BSN, Director of Clinical Education at Upstairs Solutions, it’s difficult for Assisted Living residences to train and remain up-to-date in the regulations because they’re constantly changing and are governed differently in each state. In the past, AL communities only had access to training that was developed for Nursing Homes, or at best, modified from Nursing Home content. With the Upstairs Solutions AL Library, Assisted Living facilities can access online information that is specifically developed for their needs.
The Upstairs Solutions AL Library has over twenty topics available for online learning including resident rights, neglect and exploitation, safety and fire, infection control and other subjects.
Upstairs Solution’s Maria Schmidt formerly owned an AL facility and has over 25 years of experience in long term care with a focus in quality assurance and training. She was part of a team of 22 subject matter experts who developed the AL Library. Schmidt explains that “other training companies typically have a staff nurse writing all the topics. At Upstairs Solutions, we use subject matter experts combined with instructional designers to develop AL-specific content that makes learning easy.”
Upstairs Solutions helps AL residences optimize their training by incorporating eLearning, allowing facilities to train anyone, anytime, from anywhere that they have computer access. The Upstairs Solutions Learning Management System documents compliance requirements and helps residences select the appropriate Upstairs Solutions learning modules and/or seek blended approaches with supplemental learning sources.
Tamar Abell, MA, CCC-SLP, LNHA, Principal of Upstairs Solutions adds, “The Assisted Living Library joins the Upstairs Solution portfolio of over 70 Nursing Home learning modules. We developed this AL Library because we’re committed to excellence in serving both Assisted Living communities and Nursing Homes, and to improving the quality of life and care of their residents.”

UpstairsSolutions.com currently offers more than 100 online learning modules for the elder care community as well as a sophisticated learning management system to help track employee training. Two nursing home administrators formed Upstairs Solutions originally to train their own staffs, and today the fast-growing company provides e-Learning to facilities in 24 states.
The concept of e-learning is still vague to many of us in India. But it is catching up real fast in keeping with the West. E-learning is essentially electronic learning and is delivered through a computer. In different sectors and with different people the meaning of e-learning differs. For instance, in the field of business it refers to the strategies used by a company network to give training to its employees. In many Universities, the term is used to mean a specific method to convey contents of course or program to the students online. Many higher education systems now a days are offering e-learning to their students. Online education is fast developing in the education system and is widely used in many universities and many research areas.
E-learning is undoubtedly a more flexible way of learning. Sometimes it is also used in combination with face to face learning. As e-learning initiate Bernard Luskin states “E” has a broad meaning in order it to be effective that “e” should be inferred to mean exciting, expressive, educational, extended, and excellent in addition to “electronic” that is understood widely.
Many higher education institutes prefer education to be imparted online through a Learning Management System (LMS) in which all aspects of a subject are dealt with through a consistent standard process throughout the institution. Many Universities and Colleges are now offering academic degrees and certificate courses by way of internet of which many are delivered wholly online. In addition to this many educational institutions are also offering online support services to students, like online advising, e-counseling, online buying of valuable study material, etc. Thus e-learning with its more active and interesting opportunities is gradually replacing the traditional form of teaching.
With most teenagers now using the internet everyday for supporting their school studies with easy access to web pages, students now expect technology to play a strong role in their learning. This system is not only interesting for students but also enables students to work and learn at the same time, thereby making education more flexible. This makes communication with students easier. E-learning makes the students realize their responsibility in their own learning. It is an interactive mode of learning, where the instructor plays the role more of a guide and a facilitator than of a teacher. The students get promptly involved in the process for they get quick feedback. Learners can easily access the correct and updated information whenever they want. Moreover it enables the learners to advance at a speed that suits them. The students continue getting their learning no matter where they are. Moreover there is also a discussion forum where learners can participate and discuss topics of their course with one another.
Apart from educational institutions there are many educational websites that offer such valuable services on a particular course. Such educational sites use LMS or Learning Management System to cater education to the learners. A learning management system (LMS) is a software application or Web-based technology used to plan, implement, and assess a specific learning process. The Advanced Distance Learning group, sponsored by the United States Department of Defense, has created a set of specifications called Shareable Content Object Reference Model (SCORM) to encourage the standardization of learning management systems.
LMS allows instructors to create a course, convey course content, examine students’ participation and evaluate student performance. The system also enables the learners use threaded discussion forums and also video conferencing.
It now seems, the only way to get a really good tattoo that you will always love is to design your own tattoo online. Unlike in the nineties, tattoos are now very popular these days and it seems more people are now into getting at least one tattoo on their bodies.
As with everything where there is high demand there is also a need for a high supply. In this case, the high demand for tattoos is directly proportional to the high demand for unique tattoo designs. Most people want a tattoo that is different to everyone else’s, and the only way to really do this is to design your own tattoo.
You may be asking, do I really have to go through the whole trouble of actually designing my own tattoos. Can’t you just walk into your local tattoo parlour and select from a couple of tattoo designs you like? Well, of course you could do that, but do not be disappointed when you walk in the mall the next day and see someone with exactly the same tattoo as yours.
Yes, tattoo shops usually only have a small selection of tattoo designs you could choose from, but you should really not limit yourself to these only. Do not forget a tattoo is something that is going to stay on your body for the rest of your life, unless you want to shell out extra dollars to get it removed by laser treatment.
Alright then, so what can you do to increase the chances of having a unique tattoo on your body? You could simply find a couple of tattoo designs you like and then take small parts from each one of them to create your own unique tattoo design. Access to a huge database of tattoo designs, will definitely make it easier for you to come up with your own cool tattoo idea.
Where can you get a huge database of tattoos? Glad you asked, and thanks to the internet a quick search on Google will reveal a number of online tattoo databases you can use in just a few minutes from now. I would stay away from the free databases, if you are looking for a super unique tattoo.
Once you have created your tattoo, the next thing is to make sure you get a good tattoist to replicate your design. You might want to shop around a couple of places, observing the tattoists at work and then make your informed decision based on their work.
In this article I will explain how to configure a Cisco ASA 5505 firewall to connect to dual ISPs for redundancy purposes. Suppose that we have a primary high-speed ISP connection, and a cheaper DSL line connected to a Secondary ISP. Normally all of our traffic should flow through the primary ISP. If the primary link fails, the secondary DSL connection should be utilized for Internet access. Please note that the above scenario is valid only for Outbound traffic (i.e. from our internal network towards the Internet). The functionality that I will describe below works for ASA 5505 version 7.2(1) and above.
Assume that we are assigned a static Public IP address of # from Primary ISP and another static Public IP address of # from our Backup ISP. We will use Ethernet 0/0 for connecting to Primary ISP, Ethernet 0/1 for connecting to our Internal LAN, and Ethernet 0/2 for connecting to our Backup ISP. We will create three VLANs to support our configuration. VLAN1 (the default Vlan) will be assigned to Ethernet 0/1 (inside), VLAN2 will be assigned to Ethernet 0/0 (primary-isp) and VLAN3 will be assigned to Ethernet 0/2 (backup-isp). We also have to configure two static default routes pointing to the ISP gateway address. The primary ISP default route shall have a metric of 1 and the backup ISP default route shall have a metric bigger than 1 (let’s say 2). Let us see the configuration below:
ASA5505(config)# interface ethernet 0/0
ASA5505(config-if)# switchport access vlan 2 ASA5505(config-if)# no shutdown
ASA5505(config)# interface ethernet 0/1
ASA5505(config-if)# switchport access vlan 1
ASA5505(config-if)# no shutdown
ASA5505(config)# interface ethernet 0/2
ASA5505(config-if)# switchport access vlan 3
ASA5505(config-if)# no shutdown
ASA5505(config)# interface vlan 1
ASA5505(config-if)# nameif inside
ASA5505(config-if)# security-level 100
ASA5505(config-if)# ip address # .255.0
ASA5505(config-if)# no shutdown
ASA5505(config)# interface vlan 2
ASA5505(config-if)# nameif primary-isp
ASA5505(config-if)# security-level 0
ASA5505(config-if)# ip address # 55.255.0
ASA5505(config-if)# backup interface vlan 3
ASA5505(config-if)# no shutdown
ASA5505(config)# interface vlan 3
ASA5505(config-if)# nameif backup-isp
ASA5505(config-if)# security-level 1
ASA5505(config-if)# ip address # 55.255.0
ASA5505(config-if)# no shutdown
ASA5505(config)# route primary-isp # #
ASA5505(config)# route backup-isp # #

Network monitoring is a very wide topic, since there are many facets of tis topic that we could choose to discuss; however the material this article will focus on just one of the many areas of network monitoring that could be addressed via a myriad of off-the-shelf network monitoring software available on the market.
To get a better idea this subject, you need to have a basic understanding of what the term “network monitor” actually means and to which facets of a network it would typically be applied.
What is Network Monitoring?
The phrase “Network Monitor” is not to be confused with a “Network Packet Analyzer”, which monitors your network at a lower level than the typical network monitor; network packet analyzers make it possible to perform very detailed inspections of the various types of data passing through the network. Since the focus of this article is on network monitoring, network packet analyzers are outside its scope.
The term Network Monitor, falls under the heading of “network management”, and is the term applied to a computer that is used to constantly monitor one or more other computers, or network devices on a network for predefined events, of which you would like to be notified. These events could define circumstances like a hard drive failure, high CPU usage, loss of network communication or intrusion detection; in such cases the system could be configured to automatically notify you, or whomever is the designated network administrator via various methods such as email, pager or other alarms.As you will have gathered by now, network monitors can be used in many ways depending on which particular aspects of a network are of interest to you.
Our focus will be restricted one particular network monitoring application named Spiceworks which is completely free; it allows you to perform a network inventory of computers and other active network devices in a matter of minutes. The data collected is also ideal for doing audits of both small and large scale enterprise networks.
The following is a small list of its network management features:
* Software inventory,* Network inventory* PC inventory* Network monitoring* Exchange monitoring* License monitoring
This article is not comprehensive step-by-step guide on how to use Spiceworks, but it will provide a very useful overview on how to get started with Spiceworks, by using it to take an inventory of all the active devices on your network.
Today, outsourcing website design has taken the internet world by storm. Everyone from small to large-scale organizations is outsourcing their web design requirements to a website design company. Here are some reasons why it works so well.
One of the biggest factors to make organizations outsource design to a website design company is the cost effectiveness. The cost of designing a website is a fraction of what it would cost in countries like the US or UK. In addition, the quality of the website design company need not be compromised as there are many small sized firms, who are delivering high quality work to clients.
Highly skilled talent pool:
Today, one can avail high quality services from a website design company. Countries such as India and China have many top-notch designers, who are well-versed with the English language. Many of the designers in a website design company have high-level qualifications and many years of experience in designing. Therefore, entrusting them to do a design job means a superior finished product.
Many a website design company today can boast of high-end infrastructure and facilities to conduct its design projects. These firms have access to the latest software and technologies needed to produce stunning website design. You can easily find a good quality website design company,which has excellent facilities, technology, robust infrastructure etc., which can help sustain innovative website design activities.
In terms of business principles, it is always a better idea to share risk across multiple sectors. The same concept applies when you outsource design services to a website design company. If you get the design done through only internal staff or one particular firm, there are chances it can backfire. That means all the design and website elements would suffer as a result. In contrast, if you outsource parts of your web design to each different website design company, there are lesser chances of risk.
One of the most significant advantages of outsourcing to a website design company is that your projects have scalability. That means, in future, when there are more peak loads on the website, your design will accommodate it easily. Many a website design company incorporates these tactics to ensure a more robust design.
Thus outsourcing design to a website design company has several advantages. You can find the proper website design company after assessing rates and service portfolios.

Finding an available port for your computer peripheral could be very difficult, particularly if you need several ports for your numerous devices. And the difficulty gets more challenging if what you are looking for are ports with serial, parallel and non-USB connectors, because modern computers have either reduced or removed the use non-USB ports.
If you cannot find any available non-USB ports, you can still your non-USB devices to use. Simply get yourself a USB adapter. You may ask, is a USB adapter better than the conventional expansion card? Here are the advantages of employing a USB adapter:
1. Compatibility. Whether you wish to connect the serial, parallel port, or any other non-USB ports to your computer using the USB adapter, you won’t have any problem getting them to work properly. The USB adapter allows your devices to work if connected to a USB port.
2. Price. Buying an expansion card is more costly than buying a USB cable.
3. Universality. In the past, there were certain ports that were compatible with only specific devices like printers and modems, particularly for printer ports. USB Adapter accommodates all (depending on the sort of USB adapter) non-USB connectors of any computer peripherals. This short list would include joysticks, keyboards, modems, and mouse with 9- or 25-pin serial connectors.
4. Availability. USB adapters are more plentiful than expansion cards and, in turn, are easier to locate. A local computer store or online store could be a rich resource.
5. Practicality. While most of the devices on the market have USB connectors, computers and other host systems also have USB ports. And because non-USB ports are harder to find, you can resort to a USB adapter to connect your non-USB devices to your computer.
6. No extra expansion cards required. Normally, when you link devices with a non-USB connector to your computer you would need additional expansion cards for each of these. If you would add a joystick and a modem or any peripheral with non-USB connectors, you would have to add an equal number of expansion cards for each use. With a USB adapter, all you require is a USB port to link any non-USB device to your computer.
7. Multipliable. Because a single USB port can accommodate up to 127 devices (including hubs), you can attach several non-USB devices without the need of expansion cards. This means that if you have numerous non-USB devices, all you need to do is to provide each with USB adapter and a hub to connect them to the source.
8. Simple installation. If you prefer to use an expansion card for your single device, you have to open up the computer casing in order for the expansion card to be installed on your motherboard. But that is not the end of it. You still have to turn on your computer to reboot it before the card will start working. With a USB adapter, all you have to do is to attach the connector of your non-USB device to the adapter, insert the adapter into the USB port of your computer and in no time, your device is working–even while your computer is turned on.
With all these advantages, would you still prefer using expansion cards for your non-USB devices? Definitely not! The availability of USB adapters has made connecting devices to your computer quicker, cheaper, and easier.
