Network Topologies

• Physical/Logical
• Bus
• Ring
• Mesh DOD and the Internet
• Star (compare to USB and IEEE 1394)
• Hybrid and DUN

23
Network Connectivity

• Firewall technologies
• Gateway protocol or data format converter
• Router
• Brouter/Switch
• Bridge
• Hub passive, active (repeater), smart
• Repeater

24
OS Installation / Configuration

• Organization / Topology
• Naming Conventions Corporate Policy
• How do I know I am done?
• Prove connectivity to a local share.
• Prove connectivity to the Internet.
• IMHO do NOT ANYTHING MORE without prior
  instruction/permission.

25
Addressing a machine

• Computer (NetBIOS) Name
• IP Address with subnet mask
• Default gateway address
• DNS server information
• DHCP client information vs. Static addressing
• Hardware (MAC) address - DHCP reservations
• WINS (if applicable, though legacy)
• or
• DUN speed-rated ISP telephone number, SID

26
Command Line Interface (CLI) Lab 1

• IPCONFIG
• PING
• Use hosts
• an example of NAME RESOLUTION
• View services
• Mapping network drives
• NET USE T \\vegas\public
• NETSTAT n
• NBTSTAT a mycomputer

An Installation Procedure

• Create bootable microdiskette
• Copy utilities from source files
• Copy drivers from source files
• Create system configuration files
• Reboot system from boot diskette
• Confirm OS version, system date time, access to
  storage subsystems like CDROM
• Prepare HDD medium for system installation
• Locate the installation executable
• Install the operating system

32
Networking Scope

• Extent of networked coverage, connectivity and
  function
• Physical/Logical
• LAN/WAN differences in mode of connectivity
• VAN using public utilities AOL
• MAN (campus) fiber optics, FDDI
• PAN personal area networking Bluetooth
• Functional
• SAN dedicated function
• EWN intra-, Inter-, extranet collaborative
  networking

33
Components

• NOS
• Media
• Topology
• Infrastructure
• Client/Server - Servers/Workstations
• Infrastructure - Concentrators, Routers, Switches

34
The Network Stuff

• Organization Workflows
• NOS Services, Interoperability
• Site Topology well-connected
• Media bounded, unbounded
• Hardware including network interfaces

35
Planning Information

• Any one network node
• Nodes role in the organization
• Nodes name, accessibility
• Authentication, authorization, auditing
• Nodes NOS, protocols, storage
• The size of its volumes supported services
• What licenses are required?

36

• Install a multi-boot drive with
• Windows 98SE
• FT9CH-XVXW7-7BFCM-RPR49-VDHYD
• NTWKS
• 040-0048126
