How the choice of OS platforms effects hardware design

How the choice of OS platforms effects hardware design:

The choice of operating system: Windows 8 or Android or Linux?

Imagine being able to deliver to your customers a tablet solution that bears your company’s logo as opposed to a standard off the shelf solution. Additionally, Tablet PCs by Cetrix Limited are built for business, which means systems powerful enough to run full desktop applications on Microsoft® Windows® 7/8.1 and Linux or Android and rugged enough to be used day in and day out without failing.
If you need a hybrid or tablets for more demanding work, look for devices running Intel Core processors. These range in performance from low-budget Core i3 processors to the middling Core i5, right through to the expensive but powerful Core i7. Windows tablets do have the undeniable advantage of being able to run the same desktop software you would find on a laptop or desktop PC.

Android OS

Android is popular with technology companies which require a ready-made, low-cost and customizable operating system for high-tech devices. Android’s open nature has encouraged a large community of developers and enthusiasts to use the open-source code as a foundation for community-driven projects, which add new features for advanced users or bring Android to devices which were officially released running other operating systems.
Android devices boot to the home-screen, the primary navigation and information “hub” on Android devices that is analogous to the desktop found on PCs (Android also runs on regular PCs, as described below). Android home-screens are typically made up of app icons and widgets; app icons launch the associated app, whereas widgets display live, auto-updating content such as the weather forecast, the user’s email inbox, or a news ticker directly on the home-screen
Since 2012, Android devices with Intel processors began to appear, including phones and tablets. As of November 2013, Android 4.4 recommends at least 512 MB of RAM together with an OpenGL ES2.0 compatible graphics processing unit (GPU). Android supports OpenGL ES 1.1, 2.0, 3.0 and 3.1. Some applications may explicitly require a certain version of the OpenGL ES, and suitable GPU hardware is required to run such applications.
Since Android devices are usually battery-powered, Android is designed to manage memory to keep power consumption at a minimum, in contrast to desktop operating systems which generally assume they are connected to unlimited mains electricity. When an Android application is no longer in use, the system will automatically suspend it in memory; while the application is still technically “open”, suspended applications consume no resources (for example, battery power or processing power) and sit idly in the background until needed again. Android manages the applications stored in memory automatically.

Windows-powered tablets:

Hybrid devices running Windows 8.1 get the best of both worlds: touchscreen apps from the Windows Store and desktop software such as Word, Excel and Photoshop.
Users’ overall satisfaction with their hybrids seems to have more to do with Windows and various aspects of the hardware than with the basic execution of the hybrid design. One could argue, then, that a convertible would serve just as well, and perhaps even better, given the wider selection of models and configurations currently available.
Cetrix new Windows hybrids fall into two categories based on processor


Windows 8 tablets with Intel Core processors
These are typically higher-powered tablets offering notebook-like performance and larger amounts of memory, supporting both 32-bit and 64-bit Windows 8 Pro and Windows 8 Enterprise operating systems using familiar x86/x64 processors from Intel. These can run existing desktop apps, as well as new Windows Store apps and new Windows line-of-business apps. These tablets can be a full PC replacement for business customers as they are able to run any workload that people require.
Windows 8 tablets with Intel Celeron processors
These also achieve greater mobility since they’re lightweight and have a long battery life, leveraging 32-bit Celeron processor-based system-on-chip (SoC) designs. These tablets come preconfigured with Windows 8 to give people a more predictable experience, both from the moment they are first turned on and over time. Office Home & Word, Excel, PowerPoint, and OneNote are available, although businesses will need to license this properly for commercial use.
tablets also support the new “Connected Standby” capability, and come with come in-box with driver support for the majority of PC peripherals that can be connected though the USB port.
Choosing Windows 8 and Windows RT Devices for Your Business
The capabilities needed are different when considering a new primary device for a user versus a new companion device that will be used alongside existing Windows devices. For example, companion devices typically do not need the same workload or app capabilities, while mobility and connectivity are often even more important.

Factors on Platform and Hardware chosen:

Mobility: Celeron X Light weight X Long battery life
People who are routinely carrying their devices, whether for travel to different cities or for routine meetings in their office building, appreciate tablets that are lightweight and have long battery life, enabling them to operate from wherever they are at that moment. For the best mobility, choose Windows 8 tablets with Intel Celeron processors that are lightweight and have long battery life.
Workload: Core processors X computing power X Larger amounts of memory
Some people are casual users, primarily reading e-mail, browsing the web, and running a variety of other apps that do not require much computing power. Others may be manipulating large spreadsheets, analyzing datasets, developing line-of-business software, or performing other more intensive operations. For heavier workloads, choose Windows 8 tablets with Intel Core processors that are more powerful and support larger amounts of memory.
Apps: Desktop Apps X Intel Core OR Remote App technology X Celeron
For some employees, new immersive Windows 8 line-of-business apps and Windows Store apps will allow them to perform the majority of their work, while others may require access to existing line-of-business desktop apps. These desktop apps can be either run natively on Windows 8 tablets or accessed remotely using the Remote App technology as long as appropriate connectivity is available.
When desktop apps need to be used, choose Windows 8 tablets with Intel Core processors. If connectivity to the corporate network is available, these apps can also be run remotely using the Remote App technology, supported for all types of tablets.
Type of Access: Direct Access or a VPN corporate Access X Intel Core OR Work offline X lighter processors
Some people may need access to the corporate network for their jobs, typically for using line-of-business apps. This can be done using Direct Access or a VPN connection when away from the office but on the Internet. Others need occasional online access, but frequently work offline and synchronize their files with the cloud or other remote computers. For the best corporate connectivity to corporate networks, choose Windows 8 tablets with Intel Core or Intel Celeron processors running Windows 8 Enterprise to leverage Direct Access.
Always On: constant connectivity requires lighter processors
Other users may need the constant connectivity provided by the “Connected Standby” feature so that apps can continue receiving information from networks even while the device is turned off. These apps can even notify people by playing notification sounds in cases of important events. For “always on” connectivity, choose Windows 8 tablets with Intel Celeron processors that support Connected Standby.


Organizations may need to actively manage the devices used by employees. The degree of manageability required may vary: Full manageability: All tablets running Windows 8 Pro or Windows 8 Enterprise can be joined to Active Directory to control all settings using Group Policy. Apps and software updates can be deployed to the devices using System Center Configuration Manager (push model).
Simple manageability: Some key settings can be controlled, and apps and software updates can be made available to the devices, with the users controlling the installation (pull model).
Governance: Basic security settings can be mandated for devices accessing enterprise data or e-mail. When you have specific manageability requirements, choose a tablet that offers the needed capabilities:
For full manageability, choose Windows 8 tablets with Intel Core or Intel Celeron processors that can be managed using Active Directory, Group Policy, and System Center Configuration Manager, allowing granular control and configuration of the device (including the ability to push out new versions of apps).
For simple manageability, all types of Windows tablets can be managed via Windows Intune, with security and VPN settings pushed to the devices and line-of-business apps available for users to install as needed via a self-service portal or app.
For governance, security policies (including those for passwords and encryption) can be configured on all types of Windows tablets via Exchange ActiveSync policies.
Examples of factors put to work:
Company A: a furniture retailer, decided to create a custom line-of-business app for their store salespeople, who will use this app on Windows tablets to interact with their customers to help them make purchasing decisions. For these users, mobility was the primary factor as the salespeople will carry the devices all day through their stores.
Company B: a large airline, built an app to be used by their flight crews to provide the best in-flight experience to their passengers. With Windows OS, they are assured that the devices will meet their primary mobility requirements, while also being fully manageable using Active Directory and related technologies.
Company C: has a wide range of tablet users spread across a variety of office locations and construction sites. As a result, they need devices that offer great mobility and can run a variety of apps, all while having convenient connectivity to the corporate network through the Direct Access capabilities in Windows 8 Enterprise.
University Z: decided to provide new students with Windows 8 tablets with Intel Core processors and notebooks using Windows 8 Enterprise. These students need devices that have great mobility, while still running a variety of desktop apps and workloads that vary greatly across the student body. To ensure the safety and security of their network, they also need full manageability.
When you are a solution developer and you’re keen on flexibility and versatility then your focus will be Ubuntu OS. Ubuntu tablet platform will use the same core technology as the Ubuntu desktop, it’s an easy leap to assume that developer that are after tablet integration are looking for flexibility and versatility that Linux offers. They will have desktop-like power at their fingertips.
This should mean that applications meant to run on the desktop will also run on the tablet. That certainly requires Intel processors and 8GB of RAM. Added the family of developers an interesting set of household brands’ are also looking at putting Ubuntu Touch on their own phones and tablets with Ubuntu 14.04 placing a major focus on honing the Ubuntu tablet experience.
