Study Notes
Computing Platforms
- A computing platform is a complete environment that combines hardware and software, enabling applications to run and be developed.
- It is the foundation for all computing activities.
- Key platform components include:
- Hardware: Physical computer components providing processing power.
- Operating System: Manages hardware resources, provides user interface and essential services for applications.
- Runtime Environments: Platforms that allow specific applications to run.
- Development Tools and Libraries: Software supporting application creation.
- Application Interfaces: APIs and SDKs allowing software applications and services to communicate.
- Platform characteristics:
- Compatibility: Ability to run specific applications.
- Scalability: Adaptability to increasing workload or resource demands.
- Security: Features and practices to protect applications and data.
- Performance: Efficiency and speed of operation.
- User Interface: Design and usability of the platform.
- Computing platforms are used for application development and service hosting.
IT Infrastructure
- IT Infrastructure refers to the physical and virtual resources that support an organization's IT services.
- It comprises the foundational components required to deliver, manage, and support information technology systems and services.
- IT infrastructure includes:
- Computing platforms: Provide computing services connecting employees, customers, and suppliers.
- Telecommunications services: Offer data, voice, and video connectivity.
- Data management services: Store and manage corporate data, enabling analysis.
- Application software services: Provide enterprise-wide capabilities like ERP, CRM, SCM, and knowledge management.
- Physical facilities management: Develop and manage physical installations for computing, telecommunications, and data management services.
- IT management services: Plan, develop, and coordinate infrastructure, manage accounting, provide project management.
- IT standards services: Set policies for technology use.
- IT education services: Provide training for employees in system use and managers in IT investment planning.
- IT research and development: Explore potential future IT projects and investments.
Hardware Platforms
- Hardware platforms are the physical components that form the basis for running software applications.
- Hardware components include:
- Central Processing Unit (CPU): Executes instructions, performs basic operations.
- Storage: Provides long-term storage for data and software.
- Motherboard: Houses CPU, memory, and other vital components, including connectors for peripherals.
- Power Supply Unit (PSU): Converts electrical power for internal components.
- Networking components: Hardware connecting devices, like Network Interface Cards (NICs), routers, and switches.
- Expansion Cards: Cards that can be added for additional functionality.
- Peripheral Devices: External devices connected to a computer.
- Enclosures and Cooling: Cases that house and protect components, including cooling systems like fans.
- Memory (RAM): Provides temporary storage for data and instructions used by the CPU during processing.
- Input Devices: Hardware for entering data into a computer.
- Output Devices: Hardware for displaying or conveying data from a computer.
- System Bus: Pathway for data transfer among components for efficient communication.
- Examples of hardware platforms:
- Personal Computers (PCs)
- Servers
- Mobile Devices
- Embedded Systems
- Workstations
Software Platform
- Software platforms run on top of hardware and provide services and interfaces for applications.
- Software platform components:
- Operating Systems (examples are Windows, macOS, Linux, Android, iOS)
- System Libraries
- Runtime environments (examples are Java Virtual Machine,.NET)
- APIs (Application Programming Interfaces)
Development Platforms
- Development platforms are specifically designed for software development.
- Components include:
- Code editors (Examples: VS Code, Sublime Text)
- Debugging tools
- Build systems (Example: Apache Maven, Gradle)
- Frameworks and Libraries (Examples: React, Angular, Django)
- Integrated Development Environments (IDEs) (Examples: Visual Studio, Eclipse)
- Version Control Systems (Examples: Git, GitHub, GitLab)
Virtualization
- Virtualization is the creation of virtual instances of physical computing resources.
- Multiple virtual environments or virtual machines (VMs) can run on a single physical machine.
- VMs operate independently, running different operating systems and applications.
- A software layer called a hypervisor enables virtualization, sitting between the hardware and the virtual machines.
