LECTURE POST #2: Hardware

My entrepreneurial idea is one for an app that would run on both Apple and Android products, particularly smartphones, ipads and tablets.  The app, called “Connected” is one that allows you to stay in touch with your friends easily no matter where you are.  Using Apple and Android integrated software, this app automatically shows the location of your closest friends via GPS right on your mobile device.  You will never lose your friends again!

This week in class we learned all about computer hardware and the physical units that work together to allow a computer system to work properly.  Some of these hardware units are called the motherboard, the RAM or memory, the hard drive disk, the ethernet card, the video/graphics card, the power supply, the case, the optical drive, the sound card and the CPU/processor.  The case houses all the other units and the motherboard provides the central hub in which all units connect to and take commands from.  The processor or CPU is a small chip with numerous transistors which acts the the brain of the computer system.  The CPU sits on the motherboard and gives commands to each specific units to do any particular task.

The hardware we learned about in class was mainly for a personal computer.  Although, larger more powerful computers like servers and mainframes have a somewhat similar makeup in hardware, they are not exactly like personal computers.  In the same light, mobile phones use similar hardware that is much much smaller than that of a personal computer.  In a smartphone, we can find a processor that is the brain of the operations, just like in the PC.  There is also integrated graphics, sound, and the battery acts as the power supply unit.  Most smart phones do not have an optical drive and the hard drive is in a solid state format (flash memory) which are often much smaller than a typical hard drive with platters.

Because my app will run on mainly mobile phones and mobile devices for usage, it is important that I understand the physical and virtual makeup of the device my app will be running on.  In today's age, we are trying to make the smallest, lightest, thinnest mobile devices that are still very powerful.  In order to do so, we must find new ways to make these hardware units smaller, but still as effective, if not more effective.  Because my app, "Connected" will integrate both Android and Apple OS and use Google Maps to track each mobile device location, I must find employees who know the meticulous details of each phone's physical hardware.
