It is only after instantiation that an object of a specified class exists. After an object's reference is cleared, the object also ceases to exist. The memory locations where the object's data was stored are garbage and are reclassified as unused memory available for reuse. The advent of databases introduced a further layer of abstraction for persistent data storage. Databases use metadata, and a structured query language protocol between client and server systems, communicating over a computer network, using a two phase commit logging system to ensure transactional completeness, when saving data. Modern scalable and high-performance data persistence technologies, such as Apache Hadoop, rely on massively parallel distributed data processing across many commodity computers on a high bandwidth network. In such systems, the data is distributed across multiple computers and therefore any particular computer in the system must be represented in the key of the data, either directly, or indirectly. This enables the differentiation between two identical sets of data, each being processed on a different computer at the same time. The Oxford pocket dictionary of current english.

Having a PC or a laptop is an essential part of living in the 21st century. Whether you are using it for work or to stay up-to-date with social media, truth be told, computers have taken over our lives. And to such extent that when we encounter certain issues with our pieces of technology, life itself comes to a standstill for us. In such cases, it is human nature to try and fix things.

Computer science can really help level the playing field in terms of inexpensive solutions. But Hugo also points out that it can be an equalizer in other ways. Though technology as an industry has an under representation of women and racial minorities, Hugo sees computer science as a tool for societal rebalance when it comes to gender identity, background, ethnicity and beyond. Code is code-and if you’ve created something genuinely useful, your background isn’t going to hold you back. “The App Store has the same requirements for all developers,” she points out. Hugo says it is a positive step for society that computers are blind to everything but the code. Healthcare tends to be a pretty high priority when you consider how to improve people’s lives. One of the most exciting facets of computer science is its power to improve and accelerate every other field. Genomics and personalized medicine are an excellent example of how computer science-driven technologies are accelerating healthcare progress.
