In 1980, established software development company Psion was founded by David Potter. Products from the company was named EPOC. This operating system is more focused on its use in mobile phones. In 1998, there was a collaboration between the companies Ericsson, Nokia, Motorola and Psion to explore further kekonvergensian between PDAs and mobile phones which are named Symbian. In 2004, Psion sold its stake and the results of this cooperation produces EPOC Release 5, which became known as Symbian OS v5. Operatingsystem from Symbian OS v5 it has begun to integrate the needs of the implementation of applications on devices such as PDAs in addition to cellular phones.
Then came the so-called smartphones and also emerged the latest versions of Symbian OS to something called the Symbian v6.0 or better known as the ER6 which is the first version of Symbian OS. Are open because in this system can be installed by a variety of software application developers. In early 2005, appears Symbian OS v9.1 with a new platform security system which is known as a capability-based security. The security system is set up privileges for the application to be installed on the equipment in terms of accessing the API.
Appears also called the Symbian OS v9.2 which do perbaharuan on Bluetooth connectivity technology with the use of Bluetooth v.2.0. While the latest, Symbian Symbian OS v9.3 (released on July 12, 2006) has been carrying the 802.11 WiFi and HSDPA technology as part of standard components.

EPOC
Osaris PDA by Oregon Scientific with EPOC operating system
EPOC is a family of graphical operating systems developed by Psion for portable devices, especially PDAs. EPOC derived from the early era of an era, but backfitted by engineers to "Electronic Piece Of Cheese".
EPOC16
EPOC16, originally simply called EPOC, is an operating system developed by Psion in the late 1980s and early 1990s for Psion's "Sibo" (sixteen bits) perangkat.Semua EPOC16 devices feature a 8086-family processor and 16-bit architecture . EPOC16 is a single-user pre-emptive multitasking operating system, written in Intel 8086 assembler language and C and is designed to be delivered in ROM. It supports a simple programming language called Open Programming Language (OPL) and the integrated development environment (IDE) called OVAL. Sibo devices including: MC200, MC400, Series 3 (1991-1998), Series 3a, Series 3c, Series 3mx, Siena, Workabout and Workabout mx. The MC400 and MC200, a first EPOC16 devices, delivered in 1989.
EPOC16 displaying 1-bit-per-pixel, especially the keyboard-operated graphical user interface (hardware that has been designed to have no input pointer).
In the late 1990s, the operating system is referred to as EPOC16 to distinguish it from the then-new Psion EPOC32 OS.
EPOC32
The first version of EPOC32, Release 1 appeared on the Psion Series 5 ROM v1.0 in 1997. Then, the ROM v1.1 features of Release 3 (Release 2 was never available to the public.) This is followed by a Psion Series 5mx, Revo / Revo Plus, Psion Series 7 / netbooks and netPad (which all the features of Release 5).
EPOC32 operating system, at the time simply referred to as EPOC, later renamed Symbian OS. Adding to the confusion with the name, before changing to Symbian, often referred to as Sibo EPOC16 to distinguish it from "new" EPOC.Meskipun similarity of the names, EPOC32 and EPOC16 completely different operating system, EPOC32 written in C + + from the new code base with the initial development during the mid-1990s.
EPOC32 is a pre-emptive multitasking single user operating system, with memory protection, which encourages application developers to separate their programs into the machine and the interface. Psion line of PDAs come with a graphical user interface called eikon specially designed for handheld machines with keyboard (so it might look more like a desktop GUI from the GUI palmtop). However, one characteristic's EPOC is the ease with which the new GUI can be developed based on a core set of GUI classes, a feature that has been excavated from the Ericsson R380 and so on.
EPOC32 was originally developed for the ARM family of processors, including ARM7, ARM9, StrongARM and Intel XScale, but can be compiled on the target device using some other type of processor.
During the development of EPOC32, Psion EPOC plans to license to third-party device manufacturers, and spin off its software division as Psion Software. One of the first license holder is a brief Geofox, which halted production with less than 1,000 units sold.Psion Series 5mx Ericsson to market his name called MC218, and then create the EPOC Release 5.1 based smartphone, the R380's. Oregon Scientific also released a budget EPOC devices, Osaris (known as EPOC devices only to ship with Release 4).
I n June 1998, Psion Software became Symbian Ltd., a joint venture between Psion and mobile phone manufacturers Ericsson, Motorola, and Nokia. In Release 6, EPOC became simply known as Symbian OS.
EPOC OS Releases 1-5
Work began on the 32-bit at the end of 1994.
The Series 5 device, released in June 1997, using the first iteration of the EPOC32 OS, code name "Protea", and "eikon" graphical user interface.
The Oregon Scientific Osaris is the only PDA to use the ER4.
The Psion Series 5mx, Psion Series 7, Psion Revo, Diamond Mako, Psion Netbook and Ericsson MC218 were released in 1999 using ER5. A phone project was announced at CeBIT, which Illium Phillips / Accent, but did not achieve commercial release. This release has been retrospectively dubbed Symbian OS 5.
The first phone that uses ER5u, the Ericsson R380 was released in November 2000.This is not an 'open' phone - software could not be installed. Notably, a number of released Psion prototypes-never for the next generation PDAs, including a Bluetooth Revo successor codenamed Conan using ER5u. 'The' u in the name refers to the fact that it supports Unicode.
Symbian OS 6.0 and 6.1
OS Symbian OS was renamed and imagined as a basis for a new range of smartphones. This release is sometimes called ER6. Psion provide 130 key staff for the new company and retain 31% ownership stake in the business spin-outs.
The first 'open' Symbian OS phone, the Nokia 9210 Communicator, was released in June 2001. Bluetooth support has ditambahkan.Hampir 500,000 Symbian phones shipped in 2001, up to 2.1 million the following year.
Development of different UIs was made generic with a "reference design strategy" both for 'smartphone' or 'communicator', is divided further into the design of the keyboard-or tablet-based. Two reference UIs (DFRDs it or Device Family Reference Design) shipped - Quartz and combined with the first Crystal.Yang's 'Ronneby' design became the basis for Ericsson and the UIQ interface; last reached the market as NokiaSeries 80 UI.
Then there DFRDs Sapphire, Ruby, and Emerald. Only Sapphire came to market, develop into DFRD Pearl and finally the Nokia Series 60 UI, square 'UI-based' button to the first true smartphone. The first of them is the Nokia 7650smartphone (featuring Symbian OS 6.1), which is also the first with a built-in camera, with 0.3 Mpx VGA = 640 × 480) resolution (.
Despite efforts to be generic, the UI clearly divided between competing companies: Crystal or Sapphire was Nokia, Quartz was Ericsson. DFRD left by Symbian at the end of 2002, as part of an active retreat from UI development to support delivery of 'headless'. Pearl was given to Nokia, Quartz construction is a spin-off as UIQ Technology AB, and working with Japanese companies quickly folded into the MOAP standard.
Symbian OS 7.0 and 7.0
First shipped in 2003. This is an important Symbian release which appeared with all contemporary user interfaces termasukUIQ (Sony Ericsson P800, P900, P910, Motorola A925, A1000), Series 80 (Nokia 9300, 9500), Series 90 (Nokia 7710), Series 60 (Nokia 3230, 6260, 6600, 6670, 7610) as well as several FOMA phones in Japan and Siemens SX1 (VGA camera, MMC, Bluetooth, Infraport, radio) - The first and last Symbian phone from Siemens. It also added EDGE support and IPv6. Java support was changed from pJava and JavaPhone to a standard based on Java ME.
One million Symbian phones shipped in Q1 2003, with the rate increased to one million a month in late 2003.
Symbian OS 7.0 is a specially tailored version 7.0 has more backwards compatibility with Symbian OS 6.x, partly for compatibility between the Communicator 9500 and Communicator 9210 predecessor.
In 2004, Psion sold its stake in Symbian. In the same year, the first worm for mobile phones using the Symbian OS, Cabir, was developed, which used Bluetooth to spread itself to nearby phones. See Cabir and Symbian OS threats.
Symbian OS 8.0
First shipped in 2004, one of the advantages would be the choice of two different kernels (EKA1 or EKA2). However, EKA2 kernel version did not ship until Symbian OS 8.1b. Kernels behave more or less identically from user-side, but very different internally.EKA1 chosen by some manufacturers to maintain compatibility with old device drivers, while EKA2 is a real time kernel. It deproductised 8.0b in 2003.
New APIs as well as to support CDMA, 3G, two-way data streaming, DVB-H, and OpenGL ES with vector graphics and direct screen access.
Symbian OS 8.1
An improved version of 8.0, it is available in versions 8.1a and 8.1b, with EKA2 EKA1 and kernel respectively. Version 8.1b, with a single-chip phone support but there EKA2 extra layer of security, very popular among Japanese phone companies want a real-time support but not allowing open application installation. Perhaps the most famous and the first smartphones featuring Symbian OS 8.1a Nokia N90 in 2005, Nokia's first Nseries.
Symbian OS 9
Symbian OS 9.0 is used for internal Symbian purposes only. It is de-productised in 2004. 9.0 marks the end of the road for EKA1. 8.1a is the final version of the Symbian OS EKA1.
Symbian OS has generally been held reasonable binary code compatibility. In theory the OS was BC from ER1-ER5, then from 6.0 to 8.1b. required substantial changes to 9.0, which relates to tools and security, but this should be a one-off events. Step of requiring ARMv4 to require ARMv5 not break backwards compatibility.
Symbian OS 9.1 and open source development
Released early 2005. It includes many new features related to security, including platform security module facilitating mandatory code signing. The new ARM EABI binary model means developers need to retool and the security changes mean they may have to recode. S60 platform 3rd Edition phones have Symbian OS 9.1. Sony Ericsson M600 and P990 shipping based on Symbian OS 9.1. The previous version had a defect where the phone hangs temporarily after the owner sends a large number of SMS'es. However, on September 13, 2006, Nokia released a small program to fix this flaw.Support for Bluetooth2.0 also added.
Symbian 9.1 Platform Security introduced the ability and the skeleton. To access a particular API, developers had to sign their applications with digital signatures. basic skills is a user-grantable and developers can self-sign them, while more advanced capabilities that require certification and signed through the Symbian Signed program, which uses an independent test house 'and mobile phone manufacturers for approval.For example, writing the file is a user-grantable capabilities, while Access Multimedia Device Drivers require the approval of phone manufacturers. A TC TrustCenter ACS Publisher ID certificate is required by application developers to sign.
Symbian OS 9.2
Released Q1 2006. Support for OMA Device Management 1.2 (was 1.1.2). Vietnamese language support. S60 3rd Edition Feature Pack 1 phones have Symbian OS 9.2.Nokia phones with Symbian OS 9.2 OS include Nokia E71, Nokia E90, Nokia N95, Nokia N82, Nokia N81 and Nokia 5700.
Symbian OS 9.3
Released on July 12, 2006. Upgrades include improved memory management and native support for Wifi 802.11, HSDPA. The Nokia E72, Nokia 5730 XpressMusic, Nokia N79, Nokia N96, Nokia E52, Nokia E75, Nokia 5320 XpressMusic, Sony Ericsson P1 and the other features of Symbian OS 9.3.
Symbian OS 9.4
Announced in March 2007. Provide concepts that demand paging is available from v9.3 onwards. Applications should be started up to 75% faster. Additionally, SQL support is provided by SQLite. Ship with HD Samsung i8910 Omnia, Nokia N97, Nokia N97 mini, the Nokia 5800 XpressMusic, Nokia 5530 XpressMusic, Nokia 5228, Nokia 5230, Nokia 5233, Nokia 5235, Nokia C6-00, X6, Sony Ericsson Satio, Sony Ericsson Vivaz and Sony Ericsson Vivaz Pro. Used as the basis for a Symbian, first ^ Symbianrilis platform. This release also known as the S60 5th edition, because it is the interface for the bundled OS.
Symbian OS 9.5
On March 26, 2007 Symbian Ltd. announced that v9.5 includes native support for mobile digital television broadcasts in DVB-H and ISDB-Tformat and also location services. [15]
Released as a Free and Open Source Software
Symbian Foundation was announced in June 2008 and came into existence in 2009.The aim is to publish the source for the whole Symbian platform under the OSI - and FSF-approved Eclipse Public License (EPL). Dariplatform Symbian releases Symbian OS obsolete as a standalone product.
