Study Notes
What is Computing?
- Computing is the study of how computers and computer systems work, including their construction and programming.
- It involves using computer technology to complete a given goal-oriented task.
- Computing includes the design and development of software and hardware systems for a broad range of purposes.
History of Computing
- The history of computing is longer than the history of computer hardware and modern computing technology.
- It includes the history of methods intended for pen and paper or for chalk and slate, with or without the aid of tables.
- The earliest known tool for use in computation was the abacus (invented in Babylon circa 2400 BC).
- Calculators were also a popular computation tool used in recent centuries.
Modern Day Computing
- Modern day computing is usually performed with the help of computers.
- A computer is a machine that manipulates data according to a set of instructions called a computer program.
- A computer program provides instructions to the computer hardware.
Types of Computing
- Cloud computing: the provision of computing resources on-demand over the Internet.
- Quantum computing: a type of computing that uses quantum mechanics to perform calculations.
- Ubiquitous computing: a type of computing where computers are integrated into everyday objects.
- Edge computing: a type of computing where data is processed at the edge of the network.
- Parallel computing: a type of computing where multiple calculations are performed simultaneously.
- Grid computing: a type of computing where multiple computers are connected to form a grid.
Cloud Computing
- Cloud computing is a virtual environment that delivers hosted services such as servers, databases, networking, analytics, and intelligence over the internet.
- Cloud computing architecture consists of two major parts: Front End and Back End.
- Front End: everything with which the end user interacts – UI, Browser, PC or phone.
- Back End: everything the user does not usually see and everything that processes the data.
Cloud Computing Architecture
- Client infrastructure: provides GUI for users to interact with the cloud.
- Application: any platform, such as an app or software, provided by a company through which clients can access the cloud.
- Service: manages the type of service a client uses.
- IAAS (Infrastructure as a Service): delivery of technology infrastructure as an on-demand scalable service.
- PAAS (Platform as a Service): provides runtime environment for application development and deployment tools.
- SAAS (Software as a Service): provides licensed access to the software and its functions remotely as a web-based service.
Cloud Computing Services
- Runtime cloud: offers virtual machine implementation and runtime environment.
- Storage: provides storage space in the cloud for managing and storing data.
- Infrastructure: provides services on three levels: the host, the application, and the network.
- Management: manages backend components such as storage services, applications, runtime cloud infrastructure, and security issues.
- Security: ensures data security in the cloud.
- Internet: the medium through which the frontend and backend components communicate and exchange data.
