Virtual Learning Environments
Disadvantage of VLE:
The disadvantage of VLE's is that for a non technical teacher they can sometimes appear be complicated to use.This can put some teachers off using them although many schools now require teachers to place work for their students on the school VLE.
If the VLE is run 'in house'then it usually needs to be maintained and regularly backed up.This adds to the cost of running the VLE and some schools might not have network staff or a teacher who is willing to undertake this extra work.
Another problem with VLEs are that if the internet or networks is down,then the VLE cannot be accessed.

How Mobile Phones have changed over time?
The cell phone has greatly improved over the ages. Before it was very big, larger than the usual handset for your house phones. Plus connection and sound quality wasn't as good. Today, we have color screens, texting, voicemail, internet access, built-in cameras, and so on.
Another advancement made possible by 2G was the introduction of SMS messaging, with the first computer generated SMS sent in 1992 in the UK. A year later in Finland, the first person-to-person SMS was delivered using GSM technology. As popularity grew, pre-paid mobile phones and plans emerged in the late 1990s which further popularized SMS amongst all ages.
NTT DoCoMo pioneered the first mobile Internet service in Japan in 1999 on existing 2G technologies, but it was soon replaced with their launch of the world’s first 3G network in October 2001.
While 3G was still being developed a number of “2.5G” services appeared in an attempt to bring older technologies up to speed. Unfortunately speed was the lacking factor, and while technologies like GPRS and EDGE provided improvements over standard 2G, they did not match the speed of existing 3G technologies.
Native IP or “4G”:
While no official standards exist for 4G, a few technologies have laid claim to the title. The first was WiMAX, offered by Sprint in the US but perhaps the most successful has been LTE, which is popular also in North America but non-existent in some territories such as Australia. 4G marks the switch to native IP networks, bringing mobile Internet more in-line with wired home Internet connections.

The analog technology with the first being built in Chicago in 1977.Known as the Analong Mobile Phone System (AMPS), it was built by AT&T and it took the FCC 11 years to approve AT&T’s initial proposal in 1971 before they were assigned the 824-894MHz range on which to operate AMPS.
Five years later it was the first 1G network to cover an entire country. Then came the Nordic Mobile Telephone (NMT) network in 1981. Operating in Denmark, Sweden, Finland and Norway, it was the first to feature international roaming.
Digital Cellular Networks or “2G”: Another advancement made possible by 2G was the introduction of SMS messaging, with the first computer generated SMS sent in 1992 in the UK.

Speed is of course the big advantage, with potential advancements of ten times over 3G rates. The fourth generation of mobile communication is still evolving, and we’re bound to see new standards, speed increases and coverage benefits in the next few years.

Using Mobile phones in Public
Using Mobile Phones in Public
Pros:
In airplanes and hospitals, cell phones can interfere with the functioning of delicate instruments, a serious consideration. Many states have banned cell use while driving, citing a relationship between phones and traffic accidents.
Pros: Peace and Quiet:
Many people go to places such as libraries specifically to focus and do work. Others attend church or religious services for time to worship and reflect. People who use their "cell yell" in such a setting distract others.
Pro: Inconveniencing Others:
Often cell phone users will multitask, attempting to carry on a conversation while using an ATM, driving or completing a store transaction. Their divided attention becomes an obstruction to the cashier and an inconvenience to those behind them, who must wait longer.
Cons:
Cell phones have greatly influenced society. Safety, for certain, is one benefit that they provide. If you are in an accident, you can call for help. If you are lost, if your car breaks down, wherever you go you have access to another person unless you are out of range of service. They have also been beneficial to business and industry. Because they do not charge for domestic long distance calls, communication with people across the country has been made more affordable. Business can be conducted anywhere a cell tower can reach, and today's smart phones can also help you navigate with GOS, can allow you to look up information on the Internet, and can even let you check e-mails and do work on your phone.
Con: Emergencies

Con: Emergencies
Genuine emergencies do occur, and some calls truly cannot wait. People who have sick or elderly family members, parents expecting an important call from their child, and those in the midst of a crisis believe it's acceptable to leave their phones on in public.

Email-Protocols
Email -Protocols
What is IMAP4?
IMAP4:
Abbreviation for Internet Message Access Protocol, which is a standard protocol for accessing e-mail on a remote server. It allows users to check headers of the emails; create, delete and rename mailboxes; check for new messages; permanently remove messages; search for certain parts or an entire note remotely without having to download the mail on their local hard drive. IMAP requires more Internet time as it needs continual access to the server, while handling the mail. It was developed in 1986. Its latest version is IMAP4.
What is POP3?
POP3:
POP3, which is an abbreviation for Post Office Protocol 3, is the third version of a widespread method of receiving email. Much like the physical version of a post office clerk, POP3 receives and holds email for an individual until they pick it up. And, much as the post office does not make copies of the mail it receives, in previous versions of POP3, when an individual downloaded email from the server into their email program, there were no more copies of the email on the server; POP automatically deleted them.
POP3 makes it easy for anyone to check their email from any computer in the world, provided they have configured their email program properly to work with the protocol.

What's in an image?
What's in an image?
Monochrome Bitmap (*.bmp;*.dib):
A monochrome bitmap is a type of digital image that displays only a single color, usually black. This is a type of one particular file format, which is referred to as a bitmap (BMP), and is often used in the creation of simple graphics. In a bitmap, each pixel or “picture element” of an image is represented by a particular number of bits, which are units of information. A monochrome bitmap has pixels that are only one bit, allowing each pixel to either display a single color or no color, often seen as black and white.
16 Color Bitmap(*.bmp;*.dib):
16 Color bitmap file is the same as a Monochrome bitmap fil
except it uses a range of 16 Colors instead of black and white.
256 Color Bitmap(*.bmp;*.dib):
It's a rectangular grid of pixels and each pixle is represented by a singla bit.Eight pixles are in each bitb of the bitmap.The format is often used for bitmopped text or single_colored images.This particular file uses 256 different colors.

4G Networks
4G NETWORKS
What is 4G ?
What is 4G ?
A 4G network is the fourth generation of wireless, mobile communication. The overall goal for the network is to provide a comprehensive and secure network communication solution with much faster data speeds than previous generations. While still in development, the foundations for upgrading from 3G to 4G service started in the early 21st Century as companies began to introduce new technology. New standards such as WiMax and Long Term Evolution (LTE) have been referred to as 4G, though there is some debate regarding their status.
What effect 4G will have on what we can do with our mobile phones?- In telecommunications, 4G is the fourth generation of cell phone mobile communications standards. It is a successor of the third generation (3G) standards. A 4G system provides mobile ultra-broadband Internet access, for example to laptops with USB wireless modems, to smartphones, and to other mobile devices. Conceivable applications include amended mobile web access, IP telephony, gaming services, high-definition mobile TV, video conferencing and 3D television. Recently, Android and Windows-enabled cellular devices have fallen in the 4G category. One base advantage of 4G is that it can at any point of travelling time provide an internet data transfer rate higher than any existing cellular services (excluding broadband and Wi-Fi connections).
- When 4G networks become standard, users should notice a difference. 4G technology has some persuasive benefits, which are helping accelerate the industry's push in its direction. Peak times might still be a little pokey (by the standards of people spoiled by superfast Internet service), but overall, it should be a step up from the service most cell phone users are familiar with today.

Bluetooth:
Bluetooth is a wireless technology standard for exchanging data over short distances (using short-wavelength radio transmissions in the ISM band from 2400–2480 MHz) from fixed and mobile devices, creating personal area networks (PANs) with high levels of security.
Memory card:
A memory card or flash card is an electronic flash memory data storage device used for storing digital information. They are commonly used in many electronic devices, including digital cameras, mobile phones, laptop computers, MP3 players and video game consoles. They are small, re-recordable, and able to retain data without power.
USB port:
Universal Serial Bus is a power supply between computer and electronic devices such as keyboard,digital cameras and printer.
Alarm:
An alarm device gives an audible ,visual or other form of alarm signal about a problem or condition.
Voice recorder:
A digital,handheld device that is used to record short reminders.Very lightweight and typically using AAA batteries, such devices use flash memory to hold up to 100 messages and more.
MMS:
Multimedia messaging service or MMs is a standard way to send messages that incluide multimedia content to and from mobile phones.
WiFi:
WiFi is a popular technology that allows an electronic device to exchange wirelessly including high_speed internet connection.
Hands-free device:
A hands free device is an apparatus used with cell phones that permits the user to talk on the phone without holding it. Through the assistance of this device, the user can let the phone sit in one area while talking into a microphone attached to his or her lapel. Alternatively, it may incorporate a headband that places the microphone in front of the user's mouth. In order to listen to the person on the other end, the user has an earbud speaker placed in one ear.
3G:
3G refers to the third generation of mobile telephony technology. The third generation, as the name suggests, follows two earlier generations.
Third generation wireless service, designed to provide high data speeds, always-on data access, and greater voice capacity. The high data speeds, measured in Mbps, enable full motion video, high-speed internet access and video-conferencing.
TouchScreen:
A touchscreen is a display that also serves as an input device.Some touchscreens require a proprietary pen for input though most modern touchscreens detect human touch. Since touchscreen devices accept input directly through the screen, they do not require external input devices, such as mice and keyboards. This makes touchscreens ideal for computer kiosks, as well as portable devices, such as smartphones.
GPS:
GPS stands for Global Positioning System and is a satellite-based radio navigation system that allows land, sea, and airborne users to determine their exact location, velocity, and time 24 hours a day, in all weather conditions, anywhere in the world. The capabilities of today’s system render other well-known navigation and positioning “technologies”—namely the magnetic compass, the sextant, the chronometer, and radio-based devices—impractical and obsolete. GPS is used to support a broad range of military, commercial, and consumer applications.
Video calling:
A visual communication between two people such as skype,yahoo etc.
Email:
Elextronic also known as email or e-mail , is a method of exchanging digital messages from an author to one or more recipients.
Internet:
The Internet is a global network connecting millions of computers. More than 100 countries are linked into exchanges of data, news and opinions.
SMS:
In wireless telecommunications, roaming is a general term referring to the extension of connectivity service in a location that is different from the home location where the service was registered. Roaming ensures that the wireless device is kept connected to the network, without losing the connection.
Camcorder:
A camcorder (formally a video camera recorder) is an electronic device that combines a video camera and a video recorder into one unit; typically for out-of-studio consumer video recording. Equipment manufacturers do not seem to have strict guidelines for the term usage; for instance marketing materials may present the device by its colloquial term camcorder, while full name on the package and manual is often video camera recorder
MP3 player:
A digital music player that supports the MP3 audio format, which started a revolution in online music downloads and distribution (see MP3). All portable music players, the iPod being the leading brand, support MP3 along with one or more other audio formats. CD players, whether shelf units or portable, may also play back MP3 files. For more details, see digital music player and iPod. See MP3, audioblog, podcast, codec examples and peer-to-peer network.
Predictive Text:
Predictive text is an input technology used where one key or button represents many letters, such as on mobile phones and in accessibility technologies. Each key press results in a prediction rather than repeatedly sequencing through the same group of "letters" it represents, in the same, invariable order. Predictive text could allow for an entire word to be input by single keypress. Predictive text makes efficient use of fewer device keys to input writing into a text message, an e-mail, an address book, a calendar, and the like.
voice recorder:
A digital, handheld device that is used to record short reminders. Very lightweight and typically using AAA batteries, such devices use flash memory to hold up to 100 messages and more. Messages can be retrieved sequentially or by direct access by message number. See microcassette.

It is a network of networks that consists of millions of private, public, academic, business, and government networks, of local to global scope, that are linked by a broad array of electronic, wireless and optical networking technologies. The Internet carries an extensive range of information resources and services, such as the inter-linked hypertext documents of the World Wide Web (WWW) and the infrastructure to support email.
Personal organiser:
A personal organizer, day planner, personal analog assistant, personal planner or year planner is a small book or binder that is designed to be portable. It usually contains a diary, calendar, addressbook,blank paper and other sections.
A personal organizer may also include pages with useful information, such as maps and telephone codes. It is related to the separate desktop stationery items that have one or more of the same functions, such as appointment calendars, rolodexes, notebooks, and almanacs.
Games:
A game is structured playing, usually undertaken for enjoymen and sometimes used as an educational tool. Games are distinct from work, which is usually carried out for remuneration, and from art, which is more often an expression of aesthetic or ideological elements. However, the distinction is not clear-cut, and many games are also considered to be work (such as professional players of spectator sports/games) or art (such as jigsaw puzzles or games involving an artistic layout such as Mahjong, solitaire, or some video games).

A digital music player that supports the MP3 audio format, which started a revolution in online music downloads and distribution (see MP3). All portable music players, the iPod being the leading brand, support MP3 along with one or more other audio formats. CD players, whether shelf units or portable, may also play back MP3 files. For more details, see digital music player and iPod. See MP3, audioblog, podcast, codec examples and peer-to-peer network.
Predictive Text:
Predictive text is an input technology used where one key or button represents many letters, such as on mobile phones and in accessibility technologies. Each key press results in a prediction rather than repeatedly sequencing through the same group of "letters" it represents, in the same, invariable order. Predictive text could allow for an entire word to be input by single keypress. Predictive text makes efficient use of fewer device keys to input writing into a text message, an e-mail, an address book, a calendar, and the like.
voice recorder:
A digital, handheld device that is used to record short reminders. Very lightweight and typically using AAA batteries, such devices use flash memory to hold up to 100 messages and more. Messages can be retrieved sequentially or by direct access by message number. See microcassette.
Designing Mobile Phone
This inevitably places high demands on the mobile phone's battery, and some smartphones are notorious for running out of battery power after barely a day's use.
This form of battery is favoured in consumer electronic devices, particularly portable ones, due to its energy-to-weight ratio.
They're particularly good for mobile phones as they have no memory effect, meaning that they don't lose large amounts of their maximum charge capacity, like some nickel cadmium batteries.
Mobile phone battery:
Modern mobile phones and smartphones are much more powerful devices than their predecessors and require a lot of power to run.This inevitably places high demands on the mobile phone's battery, and some smartphones are notorious for running out of battery power after barely a day's use.
What is a mobile phone battery?
Most modern mobile and smartphone batteries are Lithium-ion batteries, or LIBs.This form of battery is favoured in consumer electronic devices, particularly portable ones, due to its energy-to-weight ratio.
They're particularly good for mobile phones as they have no memory effect, meaning that they don't lose large amounts of their maximum charge capacity, like some nickel cadmium batteries.

Mobile phone designs
The design and user interface of a device is extremely important to consider.Mobile phone manufacturers have to take into account all of thier users and try to meet thier needs.This is why there are are many different types of phones available.
There are different phones available for different purposes.
1.Fashion phones:
The mobile phone has moved away from being just a tool of communication. It’s become a style statement that allows individuals to define themselves by extending their "fashionable" personality. The trend, at least for those who can afford them, is to have a phone that may not necessarily be feature-rich but which boosts one's ego when flaunted. The mobile phone that's increasingly making a statement as a fashion accessory.
These can be different shapes and have the ability to be customized,e.g.change the fascias.Buttons may be in odd places and may be inconvenient to use.They can be bright colours and highly designed,appealing to the fashion-conscious person.
Features often include high-spec cameras,the ability to store large amounts of data like photos and videos, and speakers that allow music to be played out loud.The batteries are designed to last longer but can be bulky,often making the phone larger.
2.Business phones:
The business phones are slim,sleek design,usually in black or metallic colours.They have large screens and an integrated,full qwerty keyboard.
Business phones often include speaker phone,voice activated dialling,the ability to synchronise it with other devices like netbooks and laptops etc.They also include large screens to enable work on data files,GPS to get the user to unfamiliar destinations with camera,personal digital assistant(PDA),and 3G compatibility for internet access... allowing users to carry one device rather than many.
Multifunctional phones:
Multifunctional phones are those that combine both style and business features.They have the best of both worlds e.g: high-spec features, large amounts of storage,high-speed processing, slim design with touch screens and access to the internet.

Types of Computer
TYPES OF COMPUTER
There are three different types of computers according to the principles of operation. Those three types of computers are
Computer:
Analog Computer is a computing device that works on continuous range of values. The results given by the analog computers will only be approximate since they deal with quantities that vary continuously. It generally deals with physical variables such as voltage, pressure, temperature, speed, etc.
2.Digital computer:
With these types of computers operation are on electrical input that can attain two inputs, states of ON=1 and state of OFF = 0. With digital type of computers data is represented by digital of 0 and 1 or off state and on state. Digital computer type recognizes data by counting discrete signal of (0 0r 1), they are high speed programmable; they compute values and stores results. After looking at the Digital computer type and how it functions will move to the third computer type as mentioned above.
3.Hybrid computers:
A hybrid computer combines the desirable features of analog and digital computers. It is mostly used for automatic operations of complicated physical processes and machines. Now-a-days analog-to-digital and digital-to-analog converters are used for transforming the data into suitable form for either type of computation.
Digital computer:
Deskktop computers: A desktop computer is a personal computer (PC) in a form intended for regular use at a single location, as opposed to a mobile laptop or portable computer. Early desktop computers are designed to lay flat on the desk, while modern towers stand upright. Most modern desktop computers have separate screens and keyboards.
Laptop:
Portable and compact personal computer with the same capabilities as a desktop computer. Laptop computers have an L-shape design and the screen can be lowered and closed to allow for easy transportation of the machine. The primary feature that attracts users to laptops over desktops is their portability. Laptop computers provide users the ability to run the machine using an internal battery or an outside power adaptor. Laptops have dramatically decreased in size since their introduction in 1979. Laptops are usually more expensive than standard desktops and do not have the same life-span as fixed personal computers.
Notebook:
A notebook computer is a battery- or AC-powered personal computer generally smaller than a briefcase that can easily be transported and conveniently used in temporary spaces such as on airplanes, in libraries, temporary offices, and at meetings.
Netbook:
Netbook computers are small portable computers with limited capabilities as compared to standard PC notebooks. Their small size and low weight allows them to be easily transported. However, their limited capabilities on storage and computing power restrict the user to certain applications and functions.
Personal digital assistant(PDA):Powerful handheld computing device without a keyboard, but with a screen that reads the words written (drawn) on it with a pen -like stylus. Most PDAs (like the Palm Pilot) have built-in (or accessible through attachable modules) capabilities to take notes, write letters, keep records, perform spreadsheetfunctions, read bar codes, connect to internet and other networks to download and upload data, and synchronize its data with data in a desktop computer. Wireless PDAs can connect to remote computers or databases within the range.
IPAD:
The iPad is a tablet computer developed by Apple. It is smaller than a typical laptop, but significantly larger than the average smartphone. The iPad does not include a keyboard or a trackpad, but instead has a touchscreen interface, which is used to control the device.
