This report is approximately Operating system found in lightweight devices like PDA and laptop computers etc. As the passage of time consumer needs are becoming more and more demanding and life is becoming compact so as devices are also becoming more powerful and their Operating-system also more advanced and complicated we will discuss some those most commonly used OS and their different uses and the devices they are being used made by different manufacturers and a short introduction to OS and its types.
Operating system is the most important program which allows hardware to communicate with each other and humans also. Every program needs an operating-system to run on pcs or portable devices. It is responsible of handling inputs given by user and moving them into desired outputs by using devices like keyboard, mouse, printers and monitors etc. attached to motherboard. Operating-system usually exists in hard disks of personal computers or in portable devices in flash rom storage area.
OS also organize, manage organize all file and folders on computers. The greater systems are bigger the more technical the process in those system becomes therefore the OS found in these systems are better and the task they perform are also exponential. They are capable of doing many responsibilities simultaneously without interference of one another and providing expected performance at the same time.
Different kind of OS designed for desktop or notebook computers are Glass windows which is dos established and Mac OS which is Unix structured, Ubuntu which is Linux established etc. and then for handheld there are many selections as well like Symbian Operating-system, Android, Glass windows mobile and apple iOS etc.
Real time OS
This OS is developed for devices which have limited memory and make them effective and fast less coding is used as resources are necessary and execution time needs to be little. Example is Windows CE.
Single user solitary Task
It is a advanced version of previously mentioned Real-time OS. In this kind one user is capable of doing one process at one time. The palm top or PDA fits in this kind. Example is Screen mobile.
Single end user multi Task
This is the most commonly used Operating-system type nowadays. These Operating-system can handle Multitasking and with the capacity of performing all customer tasks as multimedia system, internet, games and all commonly used tasks Example of this kind could be Windowpane 7, Mac Operating-system etc.
These will be the most powerful Operating-system of most. They are capable of controlling many users at same time and providing all of them with the resources they need. These OS are not like single end user multi activity where only 1 user can perform task at a particular time in this kind many consumer can login at same time. Example is UNIX, Linux etc.
The increasing demand of portable or lightweight devices created a new era in computing background as from calendar year 2000 and onwards the procedure of individuals regarding mobile devices changed and life started becoming fast and small day by day therefore the need of business and entertainment devices and so the mobile OS started out become popular and lots of computer hobbyist and coders started expanding faster and useful mobile OS and its own applications. The usage of internet, messages and messaging began becoming popular in devices and these facilities started out becoming a part of portable devices plus some of these are reviewed below.
PDA stands for Personal Digital Equipment usually called pocket personal computers or pocket personal computers it is an handheld device which has functionalities like phone, internet, multimedia system etc. all in pocket able size. User interact with these by having a stay called stylus or nowadays largely fingers a few of these also have built-in QWERTY keyboards for quick and better source. PDA likewise have features like hand recognition, voice popularity and gesture response.
1. 1) Types of PDA
1. 1. 1) Palm
It is kind of PDA which runs its own OS called Hand Operating-system example could be Palm TX, Hand Pilot etc. Hand became a very renowned name in portable processing industry. It played out a major role in the development of PDAs it created a variety of different editions of devices in market. Palm OS can even be found in Sony Clie, Handspring Visor and Tapwave Zodiac.
1. 1. 2) Pocket PCs
These varieties of PDA are usually based on Microsoft Glass windows Mobile Operating-system which uses Glass windows CE core. They can handle all sorts of functionalities like video recording and music playback, Web looking at built in web browser, fax mailing, and email etc. There are various manufacturers of pocket personal computers in market some of which are HP, HTC, Motorola, Dell etc.
These are smaller, lighter and generally evenly powerful in performance personal computers in comparison to desktops. They can be meant to do computing on the road. laptops received large capacity, more memory space and better processors when compared with other mobile computing devices. They run Windows Xp, Vista or 7, Macintosh OS and Ubuntu etc.
2. 1) Netbooks
These are a more recent kind of notebooks that happen to be much smaller in proportions as well as computation. They include all components as normal notebooks but in scaled down version there size is generally of the A4 size page and qwerty computer keyboard with a lttle bit less keys then normal laptops. They are capable of performing normal daily task as searching web, using word seeing HD YouTube widows (newer types only). There electric battery life change from 8 to 9 hrs. That is 4 to 5 times more than standard size laptops. Mostly Ubuntu, Google android, OR WINDOWS 7 and Glass windows 7 starter are being used as Operating-system in netbooks.
3) Other Mobile OS
3. 1) Symbian OS
This Operating-system is the most renowned in the industry and more than 85 percent of mobiles maker utilize this as standard in their devices and a lot of developers acquired become interested in growing their applications which totally changes an individual connection with Symbian jogging devices. Symbian has released different versions of its OS like Symbian series 20 or 30 for low end handsets, Symbian series 40 and 60 for mid-range and series 90 for top quality business communicators and uses 2. 5G and 3G.
3. 2) Android
This is the one of the very most promising and respected OS in comparison to others. It is verily found in devices like 3G internet tablets, cell phones and lately released a 4G version of these google android also installed in HTC EVO 4G. It is mainly based on Linux kernels therefore the development is quite easier and a lot of applications already are in market for this OS.
3. 3) iOS
It is established and developed by apple Inc. It was understands as iPhone OS before it uses apple OS X also UNIX like Operating-system. The brand new version iOS 4 is a cross types system and it uses kernel type from Darwin groundwork uses 4 abstraction tiers. It also helps multitasking and features like training video getting in touch with, VoIP (Tone over internet protocol), vocals playback etc.
Operating System of devices like PDA and Notebooks solves many individual problems as the passage of time these cellular devices are more and more compact and high performance so their Operating-system is also becoming a lot more complex to build up. As we can see from this research that lots of cellular devices companies are paying more focus on their OS because if its inadequately designed whole device no matter how best the hardware is changes whole end user view about device. If the device is sacrificing its internet connection every second or dangling or giving surprising mistakes means its Operating-system is not properly developed and examined after implementation on device under different situations and environment. The very best types of well-designed OS in mobile industry are Android os, iOs, Symbian etc. as mentioned in this survey. Notebooks on the other side can run any desktop version OS according to their hardware capacities and netbooks usually use lighter version of these OS as we have observed in this survey.
