Android is a mobile operating system based on a modified version of the Linux kernel and other open-source software, designed primarily for touchscreen mobile devices such as smartphones and tablets.

Android is developed by a consortium of developers known as the Open Handset Alliance, though its most widely used version is primarily developed by Google.

It was unveiled in November 2007, with the first commercial Android device, the HTC Dream, being launched in September 2008.

iPhone is a line of smartphones produced by Apple Inc. that use Apple's own iOS mobile operating system.

The first-generation iPhone was announced by then-Apple CEO Steve Jobs on January 9, 2007.

Since then, Apple has annually released new and iOS updates.

As of November 1, 2018, more than 2.2 billion iPhones had been sold.

As of 2022, the iPhone accounts for 15.6% of global smartphone market share.

A blockchain is a distributed ledger with growing lists of records (blocks) that are securely linked together via cryptographic hashes.

Each block contains a cryptographic hash of the previous block, a timestamp, and transaction data (generally represented as a Merkle tree, where data nodes are represented by leaves).

Since each block contains information about the previous block, they effectively form a chain (compare linked list data structure), with each additional block linking to the ones before it.

Consequently, blockchain transactions are irreversible in that, once they are recorded, the data in any given block cannot be altered retroactively without altering all subsequent blocks.

Mobile app development is the act or process by which a mobile app is developed for one or more mobile devices, which can include personal digital assistants (PDA), enterprise digital assistants (EDA), or mobile phones.

Such software applications are specifically designed to run on mobile devices, taking numerous hardware constraints into consideration.

Common constraints include CPU architecture and speeds, available memory (RAM), limited data storage capacities, and considerable variation in displays (technology, size, dimensions, resolution) and input methods (buttons, keyboard, touch screens with/without styluses).

These applications (or 'apps') can be pre-installed on phones during manufacturing or delivered as web applications, using server-side or client-side processing (e.g., JavaScript) to provide an "application-like" experience within a web browser.

A service is an act or use for which a consumer, firm, or government is willing to pay.

Examples include work done by barbers, doctors, lawyers, mechanics, banks, insurance companies, and so on.

Public services are those that society (nation state, fiscal union or region) as a whole pays for.

Using resources, skill, ingenuity, and experience, service providers benefit service consumers.

Services may be defined as intangible acts or performances whereby the service provider provides value to the customer.
