Computer Systems
Presented by: Abigail Atiwag
Computer systems refer to the combination of hardware,
software, networks, and data that work together to perform
various computing tasks and functions. Here are some key
topics related to computer systems:
Operating Systems
An operating system (OS) is software that manages computer
hardware and provides services for computer programs.
Examples of operating systems include Windows, macOS, Linux,
Unix, iOS, Android, and others. Operating systems handle tasks
such as memory management, file management, process
scheduling, device management, and user interface interaction.
Software Applications Software applications, also known as programs or apps, are designed to perform specific tasks or functions on a computer system. They can be categorized into system software (e.g., operating systems, device drivers) and application software (e.g., word processors, spreadsheets, web browsers, games, multimedia players, productivity tools).
Data Storage Data storage refers to the methods and technologies used to store and retrieve digital data. This includes primary storage (RAM, cache memory) for temporary data storage during processing, and secondary storage (hard drives, SSDs, optical disks, cloud storage) for long-term data storage. Data storage systems may use file systems, databases, and data backup solutions for data management and protection.
Computer Architecture
Computer architecture deals with the design and organization of
computer systems, including CPU architecture (processing units,
instruction sets, pipelines, cache memory), memory hierarchy (RAM,
cache, virtual memory), input/output systems, bus architectures,
parallel processing, and computer performance evaluation.
Cloud Computing Cloud computing refers to the delivery of computing services (such as storage, processing, applications) over the internet on a pay-as-you-go basis. Cloud computing models include Infrastructure as a Service (IaaS), Platform as a Service (PaaS), Software as a Service (SaaS), and cloud deployment models (public cloud, private cloud, hybrid cloud).
Artificial Intelligence (AI) and Machine Learning (ML) AI and ML technologies enable computers to perform tasks that typically require human intelligence, such as speech recognition, image recognition, natural language processing, pattern recognition, predictive analytics, and autonomous decision-making. AI and ML algorithms are used in various applications, including robotics, virtual assistants, recommendation systems, and data analysis.
Computer Programming Computer programming involves writing code and instructions that tell computers how to perform tasks and algorithms. Programming languages include high-level languages (such as Java, Python, C++, C#, JavaScript) and low-level languages (such as assembly language). Programmers use integrated development environments (IDEs) and software development kits (SDKs) for writing, testing, and debugging code.
