File sharing VS client server? Network Application tool process Appl Data icati base Client Server The file sharing model > Network SQL Appl exec icati Data Data Data base base base Interface Interface The client/ server model File sharing Client server - File are shared for a lot of machines - Database are stored in the server in the network(each machine can machines and client machines access to the shared files) can send request for appropriate data - It can create heavy network - traffic(each access to a large file can Only the records matching the potentially block of the file, showing request criteria raresent back to the system amount of information client machines so the sys never temporarily unavailable to other has heavy traffic user) Question 3. Distributed Database Topology?

It provides user with a globol view of the data. - With distributed database, the problems with implementing still exists. - Developing distributed database application requires extensive planning to anticipate the many complex possibilities. - For a large number of transactions travelling across the network the capacity of communication lines and the possible impact a system must be carefully considered. Chapter 12: THE TCP/IP PROTOCOL SUITE. Question 1. The OSI model? - OSI model, adopted in 1983 by IOS , which is a framework for defining standards for linking hetenogenerous computer - The communication function are pastitioned into a vertical set of layers. Each layer performs are lated subset of the functions required to communicate with other sys - The OSI layers  Physical: concerned with transmission of unstructured bit stream over physical medium, deals with the mechinical, electrical, functional, and procedual characteristrics to access the physical medium  Data link: provides for the reliable transfer of information across the physical link, send blocks of data with the necessary synchronization, error control, and flow control.  Network: provides upper layers with independence from the data transmission and switching technologies used to connect systems, responsible for establishing, maintaining and terminating connections  Transport: provides rediable, transparent transfer of data between end points, provide end_to_end error recovery and flow control.  Session: provides the control structure for communicaton between applications, establishes, manages, and terminates connections between cooperating applications.  Presentation: provide independence to the application processes from difference in data representation(syntax)  Application: provide access to the OSI environment for users and also propvides distributed information services User oriented Application Users of transport Presentation service End to end Session connection oriented Transport Network Point to point Data link Network service link oriented Physical Perspectives on the OSI architecture Question 2. Protocols?

W W O O N N y y bu bu to to k k lic lic C C w w m m w w w w o o .c .c .d o .d o c u -tr a c k c u -tr a c k Both OSI and the TCP/IP protocol suite deal with communications among hetrnogenerous computers Both are based on the concept of protocol and have many similarities a. TCP/IP protocol architecture TCP: Transmission Control Protocol IP: Internet Protocol - The TCP/IP protocol architecture is based on a view of communication that involves three agents: processes, hosts, and networks - Communication between processes takes place across networks to which the hosts are attached - A network need only be concerned with routing data between hosts, as long as the hosts agree how to direct data to processes - It is natural to organize protocols into four layer i. Network access layer: contains those protocols that provide access to a communication network ii. Internet layer consists of the procedures required to allow data to traverse multiple networks between hosts iii. Host_host layer: containts protocol entities with the ability to deliver data between two processes on different host computers iv. Process/ application layer: contains protocols for resource sharing and remote access b. Operation of TCP/IP Application Application TCP TCP OS IP OS IP Network access Network access protocol 1 protocol 2 IP Network 1 Network 2 Netwo NAP Communications using the TCP/ IP protocol architecture NAP: Network Access Points - IP is implemented in all of the end systems it keeps track of blocks of data to ansure that all are dilivered veliably to the appropriate application - For successful communication, every entity in the over all sys must have a unique address, two level of addressing are needed  Global Internet Address(for communication)  Ports(for service) Try your best, you will get the best!
