Mobile devices, what makes a good mobile device?

Mobile devices

We use a wide range of technology devices and systems to communicate and share data. While the components are similar, how the components are used and perform can differ a little. The features on a mobile device can affect both the performance and user experience. More powerful features provide a better experience but reduce the battery life.

Modern mobile devices use a system on a chip (SoC) technology to combine the CPU and GPU onto one chip. This has many benefits, including making the device smaller, easier to manufacture, faster, and needing less power.

The battery life for a mobile device is important, as people need to be able to use it for at least a da and preferably more then a day. Recharging batteries takes time, and inconvenience for the user and reduces mobility. Designers therefore take a lot of care to design mobile devices with just the right mix of processing power and battery life.

The amount of electrical power the processing consumes is not an issue, with a traditional platform such as a desktop PC, as mains electricity is plentiful there is little extra cost involved in running a powerful computer.
The size and weight are also less of a concern then for mobile devices, which needs to be portable and convenient to use.

The main components of a computer with brief descriptions.

Main components of a computer Motherboard – The main printed circuit board (PCB) where all the other system components plug in. CPU – Central processing unit, each computer has at least one CPU or a microprocessor, which runs instructions contained in computer programs and undertakes input/output operations. The CPU has many parts, including arithmetic and logic (ALU) unit, control unit, registers, etc. Arithmetic and logic unit – This completes basic calculations (arithmetic) and comparisons (logic). Comparisons are used in sorting and searching operations. Control Unit – Each machine code instruction is extracted from memory. Decoded and run calling on the ALU when necessary. The output is either written  to the register for fast recall as part of subsequent instructions or back to main memory. The control unit is there to make the rest of the computer hardware do whatever is the result of the completed instruction. Registers – There are several types of register whithin the CPU a

Programming concepts, high-level programming languages, low-level programming languages, machine code, hardware, characteristics of high/low level programming, and flow charts.

Programming concepts Professional programmers use specialised skills and creativity to write programs. Some people find programming easy and fun.  The programming concept you need to understand are described below. Application software package This is the end result of programming. When an application is running, the user interface is what you see and interact with by typing or using buttons. Applications software packages are created by programming with a high-level programming language and are used to solve problems and to entertain. High-level programming language A high-level programming language is one that is quite close to natural human language (rather then computer language, aka machine code). This is what most programmers use to write programs.  Examples of high-level programming language are C# (pronounced ‘C Sharp’), C++, Java, and Visual Basic. Microsoft Office applications, including excel also offer high-level programming functionality using VBA (virtual basic for applic

What is ROM? (Read only memory)

ROM Read-only memory (ROM) is memory that keeps the contents when the power is switched off. PCs have ROM on the motherboard and keep setup information such as the boot sequence to control whether the computer starts with the hard drive (normal) or the DVD drive (to reinstall a operating system).
