2. A tablet computer, or simply a tablet is a onepiece mobile computer.Available in variety of sizes tabletscustomarily offer a screen diagonal more than7(18cm), differentiating themselves throughsize from functionally similar smart phones orpersonal digital assistants.Tablet personal computers are mainly basedon the x86 IBM-PC architecture and fullyfunctional personal computers employing aslightly modified personal computer OS(suchas Windows or Linux) supporting their touchscreen, instead of a traditional display, mouseand keyboard. 3. Tablets have also appeared in foldable Bookletformat that offer the user dual touch screens, andcan be used as a notebook by displaying a virtualkey board on one of the displays.A typical tablet personal computer needs to bestylus driven, because operating the typicaldesktop based OS requires a high recession toselect GUI widgets, such as a close windowbutton.OPERATING SYSTEMS IN TABLET1.

It's the largest installed base of any mobileplatform and growing fastevery day anothermillion users power up their Android devices forthe first time and start looking for apps, games,and other digital content.Android gives you a world-class platform forcreating apps and games for Android userseverywhere, as well as an open marketplace fordistributing to them instantly. 5. A processor is the logic circuitry that respondsto and processes the basic instructions that drivea computer The processor is the component that physicallytells these devices what to do and when to do it.THE JOB Though the processor is the key to verycomplicated devices, what it physically does isactually very simple. It carries out a few simpleinstructions that tell whatever device it isembedded in how to work. 6. The most amazing feature of processing chipsis how small they are. The side of a chip can beup to 1 inch long, but the chip itself can containthousands of components. The material used tomake the chip is silicon, sliced wafer-thin.The physical composition of silicon makes it theperfect material on which to build the circuitsthat make up a processor chip. Using laserlight, the circuit design is etched onto thesurface of the silicon. Once drawn, thetransistor portions, or wiring, are built onto thechip. The spacing between transistors can beas narrow as 60 nanometers, which is just a 7. Boolean logic is the processing language used bythe chip to communicate bits ofinformation throughout the computer. In its simplestform, Boolean logic uses a two-value logic system of"true" and "false" to translate electrical currents intoinformation that can be used by the system.As technology becomes more advanced, theprocessor chip continues to decrease in size. Thecompartmentalizing of processor capabilities meansreduced cost and greater efficiency.As such, nanotechnology explorations are well ontheir way. Current research attempts are focusing onapplying the processor chip model on the molecularlevel. Once achieved, the speed and efficiencystandards we see today become painfully slow bywill comparison. 8. Intels cofounder, Mr. Gordon Moore, predicted thatthe processing power could be doubled every 18-24 months. This is measured by doubling thetransistor counts in a microprocessor. Thisprediction is now known as Moores Law.Pn = Po 2nWherePn = processing power in future yearsPo = processing power in the beginning year 9. n = number of years to develop a newmicroprocessor divided by 2, i.e., every two years 10. In 1988, the number of transistors in the Intel 386SX microprocessor was 275,000. What were thetransistor counts of the Pentium II Intelmicroprocessor in 1997?SOLUTION: If Intel doubles the number of transistorsevery two years, the new processor would havePn = 275,000 2n (where n = 9/2 = 4.5)= 275,000 22.63= 6.2 million transistorsIn 1997, the Pentium II had 7.5 million transistors.In other words, in the last 9 years, Intel has beendoubling the number of transistors in itsmicroprocessors in less than every two years. 11. COMPUTER SCIENCEAndroid is an OS based on Linux. Hence, deepinside, Android is pretty similar to Linux. 12. The diagram shows four basic apps (App 1, App 2,App 3 and App 4), just to give the idea that there canbe multiple apps sitting on top of Android.Scratching further below the applications, we reachthe application framework, which applicationdevelopers can leverage in developing Androidapplications.The framework consists of certain entities; majorones are:1. Activity Manager2. Notification Manager3. Views4. Resource Managers5. Content Provider 13. LibrariesThis layer holds the Android native libraries.Android RuntimeThe Android runtime consists of the Dalvik VirtualMachine. It is basically a virtual machine forembedded devices, which like any other virtualmachine is a bytecode interpreter.KernelThe Android OS is derived from Linux Kernel 2.6 andis actually created from Linux source, compiled formobile devices. The memory management, processmanagement etc. are mostly similar. The kernel actsas a Hardware Abstraction Layer between hardwareand the Android software stack. 14. ENGINE TESTING USING TORQEANDROID APPLICATIONTechnical information about an engine while runningcan be viewed with the help of an android tabletapplication called torqueA Bluetooth OBD2 adapter is connected t diagnosticssocket on the car and paired to a tablet via Bluetoothcontaining the torque app.Torque is a vehicle/car performance/diagnostics tooland scanner that uses an OBD2 Bluetooth adapter toconnect engine management/ECU.The app needs Bluetooth OBD2 adapter to work.The adapter is small and plugs into the diagnosticsocket on the car which gives your phone access . 15.
