Computer Network notes.docx
A network is a set of devices (often referred to as nodes) connected by communication links. A node can be a computer, printer, or any other device capable of sending and/or receiving data generated by other nodes on the network.
“Computer network’’ to mean a collection of autonomous computers interconnected by a single technology. Two computers are said to be interconnected if they are able to exchange information.
The connection need not be via a copper wire; fiber optics, microwaves, infrared, and communication satellites can also be used.
Networks come in many sizes, shapes and forms, as we will see later. They are usually connected together to make larger networks, with the Internet being the most well- known example of a network of networks.
There is considerable confusion in the literature between a computer network and a distributed system. The key distinction is that in a distributed system, a collection of independent computers appears to its users as a single coherent system. Usually, it has a single model or paradigm that it presents to the users. Often a layer of software on top of the operating system, called middleware, is responsible for implementing this model. A well-known example of a distributed system is the World Wide Web. It runs on top of the Internet and presents a model in which everything looks like a document (Web page).

Data Abstraction and Independance (1).pptx
This document discusses data abstraction and data independence in database systems. It describes three levels of data abstraction: physical level, logical level, and view level. The physical level concerns how data is actually stored, the logical level comprises information stored in tables and relationships between entities, and the view level allows users to view data in rows and columns. Data independence means the ability to modify schemas without affecting other levels - physical level data independence allows changing the physical storage without impacting logical or view levels, while logical level data independence modifies the conceptual view without affecting external applications or user views.
3Tier_Architecture.pptx
This document proposes a three level database architecture. The three levels are the external, conceptual, and internal levels. The external level allows users to view desired data without knowing database schema details. The conceptual level describes the database design, relationships, and implements constraints and security. The internal level describes how data is physically stored and allocates storage space. The goal of this three tier architecture is to separate user applications from the database, support DBMS characteristics, provide program-data independence, and support multiple views of data.

- 1. Prepared by: Asst. Prof. Neha A. Sahuji
- 2. What is Computer Network? Goals of Computer Network. Protocols, Standards, Standard Organizations. Data Flow.
- 3. A computer network often simply referred to as a network, is a collection of hardware components, which are interconnected by communication channels that allow sharing of resources and information with respect to certain set of rules / protocols via OS / software. Elements of Network; 1. Hardware equipments 2. Network OS / software 3. Communication channel 4. Information / Data / Recourse
- 4. Network: a set of devices connected by media links.
- 5. 1. Resource Sharing – Many organization has a substantial number of computers in operations, which are located apart. Ex. A group of office workers can share a common printer, fax, modem, scanner etc. 2. High Reliability – If there are alternate sources of supply, all files could be replicated on two or, machines. If one of them is not available, due to hardware failure, the other copies could be used.
- 6. 3. Inter-process Communication – Network users, located geographically apart, may converse in an interactive session through the network. In order to permit this, the network must provide almost error-free communications. 4. Flexible access – Files can be accessed from any computer in the network. The project can be begun on one computer and finished on another.
- 7. A set of rules governing data communications. 1. Syntax: format of data block 2. Semantics: meaning of each section 3. Timing: speed and sequencing Standards: A common set of rules. 1. De facto (in practice) standards (not approved but widely adopted) 2. De jure (in law) standards (approved by an organization)
- 8. IEEE (Institute of Electrical and Electronics Engineers) ANSI (American National Standards Institute) ITU (International Telecommunications Union – formerly CCITT) ISO (International Organization for Standards) EIA (Electronic Industries Association)
- 9. Transmission mode(Data Flow) means transferring of data between two devices. It is also known as communication mode. Buses and networks are designed to allow communication to occur between individual devices that are interconnected. There are three types of transmission mode.
- 11. In Simplex mode, the communication is unidirectional, as on a one-way street. Only one of the two devices on a link can transmit, the other can only receive. The simplex mode can use the entire capacity of the channel to send data in one direction. Example: Keyboard and traditional monitors. The keyboard can only introduce input, the monitor can only give the output.
- 12. In half-duplex mode, each station can both transmit and receive, but not at the same time. When one device is sending, the other can only receive, and vice versa. The half-duplex mode is used in cases where there is no need for communication in both direction at the same time. The entire capacity of the channel can be utilized for each direction. Example: Walkie- talkie in which message is sent one at a time and messages are sent in both the directions.
- 13. In full-duplex mode, both stations can transmit and receive simultaneously. In full_duplex mode, signals going in one direction share the capacity of the link with signals going in other direction, this sharing can occur in two ways: 1. Either the link must contain two physically separate transmission paths, one for sending and other for receiving. 2. Or the capacity is divided between signals travelling in both directions. Full-duplex mode is used when communication in both direction is required all the time. The capacity of the channel, however must be divided between the two directions. Example: Telephone Network in which there is communication between two persons by a telephone line,
