Computer Technology in Transportation- Certain safety features or luxuries, such as airbags, cruise control, anti-lock brakes and automatic transmission, all rely on computer technology to function.
- 13. Introduction to Computing What are the types of computing? A computer system uses many devices, arranged in different ways to solve many problems. This constitutes a computing environment where many computers are used to process and exchange information to handle multiple issues.
- 14. Introduction to Computing What are the types of computing?
- 15. Introduction to Computing 1. Personal Computing Environment In the personal computing environment, there is a single computer system. All the system processes are available on the computer and executed there. The different devices that constitute a personal computing environment are • laptops, • mobiles, • printers, • computer systems, • scanners • etc.
- 16. Introduction to Computing 2. Time Sharing Computing Environment 1. The time-sharing computing environment allows multiple users to share the system simultaneously. 2. Each user is provided a time slice and the processor switches rapidly among the users according to it. Because of this, each user believes that they are the only ones using the system. • Example • UNIX server OS. • Linux server OS. • Windows NT server. • Windows 2000 server.
- 17. Introduction to Computing 3. Client Server Computing Environment 1. In client-server computing, the client requests a resource and the server provides that resource. 2. A server may serve multiple clients at the same time while a client is in contact with only one server. 3. Both the client and server usually communicate via a computer network but sometimes they may reside in the same system.
- 18. Introduction to Computing 4. Distributed Computing Environment 1. A distributed computing environment contains multiple nodes that are physically separate but linked together using the network. 2. All the nodes in this system communicate with each other and handle processes in tandem. 3. Each of these nodes contains a small part of the distributed operating system software.
- 19. Introduction to Computing 5. Cloud Computing Environment 1. The computing is moved away from individual computer systems to a cloud of computers in cloud computing environment. 2. The cloud users only see the service being provided and not the internal details of how the service is provided. 3. This is done by pooling all the computer resources and then managing them using a software.
- 20. Introduction to Computing 6. Cluster Computing Environment 1. Cluster computing is a collection of tightly or loosely connected computers that work together so that they act as a single entity. 2. The connected computers execute operations all together thus creating the idea of a single system. 3. The clusters are generally connected through fast local area networks (LANs)
- 21. Introduction to Computing What Is the Purpose of the Computer? The purpose of the computer is to : • perform calculations. • store information • retrieve data • and process information. • A computer has programmed data or computer language that tells the computer how to fulfill its purpose.
