TAILIEUCHUNG - Lecture Network + Guide to Networks (5th edition) - Chapter 0: Network operating systems

Lecture Network+ Guide to Networks (5th edition) - Chapter 0 introduce Network operating systems. Objectives of this chapter: Describe characteristics common to all NOSs (network operating systems), compare and evaluate NOSs to select the right one for your Network, define the requirements for and features of the Windows Server 2008 NOS,. | COURSE TECHNOLOGY 1 CENGAGE Learning Network Guide to Networks 5th Edition Network Operating Systems Characteristics of Network Operating Systems Based on client server architecture NOS manages resource sharing NOS provides many other functions - Some built in - Some configured at installation Default customizable settings NOS components vary by NOS version and type 9 7 2011 Objectives Describe characteristics common to all NOSs network operating systems Compare and evaluate NOSs to select the right one for your Network Define the requirements for and features of the Windows Server 2008 NOS Define the requirements for and features of UNIX and Linux NOSs Create users and groups and assign file permissions on systems running Windows Server 2008 and UNIX Network Operating Systems and Servers Networks use servers exceeding minimum hardware Determining optimal server hardware - Questions What kinds of applications will run on the server How many clients will connect to the server How much storage space will each user need How much downtime if any is acceptable What can the organization afford 1 Network Operating Systems and Servers cont d. Determining optimal server hardware cont d. - Applications influence Type of application Resources used Processing burden - Vendor reputation requirements High quality dependability excellent technical support Reliable server - Spend as much as necessary Component failure widespread effects Client server Communication Logon process Redirector - Intercepts requests determines where to handle File access protocol - Windows XP client communication with Windows Server 2008 CIFS Common Internet File System Older protocol SMB Server Message Block - Broad support allows every client type to authenticate access resources 9 7 2011 Client Support Important NOS function - Allows efficient communication resource sharing NOS client support tasks - Creating and managing client accounts - Enabling clients to connect to the network - Allowing clients
