The Parts: An Analysis

The insides of a tablet are quite similar to a typical computer. Here is a list of the general hardware parts of a tablet: touchscreen display, front camera, light sensor, buttons, power key, volume key, USB connector, power connector, external storage unit, SIM card cover, headphone jack, speaker/s, the microphone and sometimes a stylus. Most of these parts should be quite familiar so I’ll go through the parts you might not know. The light sensor is found near the camera and detects light levels. The USB cable is for charging its battery as well as connecting to a computer. The external storage unit is for a memory card to gain extra storage.

The sensors in a tablet are more or less the same as the ones in a phone. The proximity sensor – used for various things, namely: rejecting accidental screen touching, saving battery by reducing light levels if no-one is close by and detecting voice levels. The GPS sensor – helps navigate with the help of GPS satellites. The light sensor, is as mentioned before. Accelerometers – help with detecting the rate of change for orientation. Compass – detects direction. Finally, the gyroscope which is also another directional sensor that detects tilt about an axis. These sensors are essential to tablets in helping them process information. For the CPU of tablets, the idea is that they generally use smaller processors when compared with a computer. It uses a microprocessor, this is mainly to cut down on space and to reduce heat generation. Examples of processors includes Cortex-A series, AMD series and Intel Core series.

The tablet’s output is the same as any electronic screen device. Data is processed within the tablet which can be considered an output. This is shown on the screen, another output. Printing is another form of output, which is physical. Tablets have had the capability of printing ever since Apple’s iPad. It could also be done within a software. For example, if you were to use a calculator and entered ‘3+5=’, then the output in the end would be ‘8’. The tablet also has sound output; music, games or even online. The point is, the tablet’s output capabilities are the same as a typical computer.
