Android P is the ninth generation of the Android operating system for mobile phones. It will succeed the current operating system, Android 8.0 (Oreo) when it is released in the second half of 2018. Google have said that it will launch with the wave of new mobile phones near the end of the year. The new operating system will allow mobile phones to take advantage of some new features that are aimed at improving security for the users, while also streamlining the interface to speed up productivity for the users.

Global System for Mobile telecommunications is the standard digital mobile telephone system used around the world, but particularly in Europe, Asia and Australia. Telstra, Vodafone, Optus and Hutchison all own and operate GSM networks, and they supply numerous resellers with network capacity so they can also compete for customers.

SDRAM – acronym for Synchronous Dynamic Random Access Memory, rated in MHz. SDRAM differs from much slower DRAM in that it allows an improved and more stable method of sending its stored information in sequence with a computer's microprocessor clock speed and system bus, handling multiple commands and improving the overall speed, accuracy and security of transfer. In essence, SDRAM gives a computer or similar device a superior chipset with the ability to process more data at once, in less time.

SD, or "Secure Digital", is a type of memory card format for use in portable devices such as cameras or cellular phones. Standard ranges of SD card capacities are 4 MB to 2 GB. Larger cards are possible for using a newer, high-capacity technology called SDHC, which can only be used with newer, compatible devices. The left side of the card may include a notch which will render the SD card write-protected.

This relatively new technology is a format, technically known as micro secure digital, but most commonly known as a flash memory card that is removable from any compatible mobile phones and several other electronic devices. MicroSD cards can range from 64 mega-bytes(MB) to 16 giga-bytes(GB) in size of capacity, while also being the smallest memory card currently available in the market. It allows users to store more data such as documents, mp3s, video and voice recordings, and/or any other media, that they would not have been able to with the device without the microSD card.

Internal Memory is the main memory in the data storage of a phone or computer. Internal Memory usually refers to the random-access memory which takes form as integrated circuits that store information in some sort of order. This Internal Memory can also be called main or core memory which is used after processing a job and that information is retained in the memory. That information can be accessed and processed again. Silicon chips or semi-conductors are used to store Internal Memory.

MIDI is short for Musical Instrument Digital Interface. The MIDI is a music industry standard file protocol that allows music to be digitally recorded onto an extremely small amount of space and shared with mobile phones, personal computers, or other devices that have MIDI sequencer capabilities. MIDI can both record and play back music in the same manner as an old cassette record/play machine could only MIDI files also include the technology that allows all instruments on the recording to talk to each other as well.

"MPEG means ""Motion Picture Experts Group"" and it's used to encode audiovisual information's as film, music, images etc. with digital compress format. MPEG is using loosy compression where are pieces of audio and/or video splitted then some of them (for example every second) deleted, then quantized and linked again. The first MPEG standard was establishes in 1988 and it's called MPEG-1. This format is used for encode and decode digital support panel with speed from 0,9 to 1,5 Mbit per second. It includes Video CD and MP3 files. There are another capital MPEG formats : - MPEG-2 - used for television broadcast, TV digital cable or DVD Video (speed is from 1,5 to 15 Mbit per second ). - MPEG-3 - used for HDTV but afterwards assigned to MPEG-2. - MPEG-4 - used for low bit speed media format. There are several other MPEG formats : MPEG-A,B,C,D,E used mainly for applications."

Buyer beware! Read the fine print. So often in Telecommunication Contract's fine print, there are hidden or should I say 'hard to find' conditions or extra fees. Eg. You enter a 'No Contract' (term not fixed) agreement, only to find that there is an 'early exiting' or 'cancellation fee' for those wishing to leave prior to 6 months after joining. It's a play on words and these term and conditions are binding. So buyer beware and ask about fees such as early exiting and termination.

WLAN is short language for wireless local area network. This technology gives devices the freedom to send and receive information without being connected to the internet using cables and external modems. The technology behind this breakthrough in computer use is called spread-spectrum or OFDM. A group of large wireless areas are being established that include not only malls and restaurants, but entire cities.

WiMAX or Worldwide Interoperability for Microwave Access is a newer protocol used to transfer data back and forth between communications points for the purpose of Internet access or VOIP (Voice Over IP) calls. WiMAX is the next generation wireless Broadband access protocol and can maintain speeds of up to 10 Mbps (Mega Bits per Second) at a distance of up to 6 Miles. This range and speed make WiMAX a viable alternative to the "Last Mile" where DSL or Cable are not probable. WiMAX uses SOFDMA (scalable orthogonal frequency-division multiple access, which automatically assigns frequency subnets to users) and is contentious meaning that one contends for the WiMAX Access Points attention and therefore may not be a viable solution for applications such as IPTV.

Wi-Fi- specifications in the 802.11 family is a term for certain types of wireless local area network (WLAN) ; products using the 802.11b standard was only applicable; to products that use any 802.11 standard; an evolving set of wireless network standards known as the 802.11 family it was part of ; can be susceptible to access by unauthorized users who use the access as a free Internet connection; unauthorized users who use the access as a free Internet connection can be susceptible to access; technology; different wireless devices; organization called the Wi-Fi Alliance created it; originally founded in 1999 as WECA.

CDMA is short for Code Division Multiple Access. This is a form of digital technology is used on a mobile phone that utilizes a digital-style broadband. It codes messages to be deciphered by the proper receiver. WCDMA is a wideband version of CDMA that increases transmitting rates in all GSM systems. WCDMA is also known by the name of DS or data sequencing mode to some mobile phone users.

WAP is the term used for Wireless Application Protocol. The WAP technology allows worldwide mobile data applications to work on a variety of different levels. WAP gives unique independent access to internet and telephone services by determining the correct application or communication protocols for each wireless device to use.

Mobile phones use frequency bands. A tri-band is a mobile phone that has the capability to use three different frequency bands. The use of more than a single band for a mobile phone allows the user to have better coverage outside of their normal coverage area.

MHz – MHz measures frequency in units of time. It can also be expressed as number of cycles per second. MHz is accepted as the basic unit of frequency and is used worldwide in several different ways. Hertz are used to measure radio, audio and other events which are part of the modern metric system called the International System of Units. The word Hertz is both singular and plural in English, and can be applied to any event in time for measurement. Frequency is energy and the term MHz is used to measure that energy in time.

IEEE or IEEE 1394 technology was developed by Apple in 1986. This multimedia connection allows the high bandwidth data and real-time data to mix with simple devices such as personal computers and units such as VCR players, printers, televisions, or digital cameras all in one connection. The IEEE 1394 technology is the ability to mix low speed and high speed in a manner that all users need today for their multimedia enjoyments.

HSPA or High Speed Packet Access is a collective term encompassing both HSDPA (High Speed Downlink Packet Access) and HSUPA (High Speed Uplink Packet Access). The two protocols provide improved speeds and efficiencies by better utilization of the spectral modulation, giving speeds that are 7 times faster than current 2G networks. With HSDPA, one can attain download speeds of 14 Mbps. HSUPA can reach speeds of 5.76 Mbps. Since most devices receive more downloads than provide uploads, the speed favors the download side.

HSDPA or High Speed Downlink Packet Access is a protocol used in Wireless access networks and will be available with 3G. It is akin to the evolution of the EDGE protocol available on today's 2g networks. HSPDA allows for downlink data rates of 14 MBPS (Mega Bits per Second) which is faster than most home networks. It is clear that today's networks will not be able to satisfy the bandwidth demand much longer. Therefore, more advanced protocols, like HSDPA are being considered. Although HSPDA is most likely the top contender, WiMAX and EV-DO protocols are in the running as well.

HSCSD stands for High Speed Circuit Switched Data, which is an improved wireless data transfer using a dedicated circuit-switch communication channel. With speeds of up to 38.4 Kbps, HSCSD allows for wireless data transfers that are comparable to computer modem speeds. For mobile users, this means that users can access the Internet, fax and transfer data at much greater speeds than with the previous CSD, or Circuit Switched Data.
