A Comparative Study of OSI and TCP/ IP Models
Get PDFThe Internet protocol suite is the computer networking model and set of communications protocols used on the Internet and similar computer networks. It is commonly known as TCP/IP, because it’s most important protocols, the Transmission Control Protocol (TCP) and the Internet Protocol (IP), were the first networking protocols defined in this standard. Often also called the Internet model, it was originally also known as the DOD model, because the development of the networking model was funded by DARPA, an agency of the United States Department of Defense. TCP/IP provides end-to-end connectivity specifying how data should be packetize, addressed, transmitted, routed and received at the destination. This functionality is organized into four abstraction layers which are used to sort all related protocols according to the scope of networking involved. From lowest to highest, the layers are the link layer, containing communication technologies for a single network segment (link); the internet layer, connecting hosts across independent networks, thus establishing inter-networking; the transport layer handling host-to-host communication; and the application layer, which provides process-to-process application data exchange. Our aim is describe operation & models of TCP/IP suite in data communication networking
A Study of Distributed Database Management System
Get PDFA Database is a collection of data describing the activities of one or more related organizations with a specific well defined structure and purpose. A Database is controlled by Database Management System (DBMS) by maintaining and utilizing large collections of data. Distributed computer applications built from off the shelf hardware and software are increasingly common at networked computers communicate and coordinate their activity only by-passing messages.[2] Distributed Database System the database is stored/spread physically across computers or sites in different locations that are connected by some form of data communication network. They may be spread over WAN or LAN. The computers may be of different types such as IBM Mainframes, VAXs, SUN workstation, PCs etc managed by different operating systems and each fragment of the data base may be managed by a different DBMS such as Oracle, Ingress, and Microsoft SOL server. This paper presents an overview of Distributed Database System[1
