Chapter 1 Intro to
Networking
 Beginnings of networking
 Stand alone computers
 Sneakernet
 Why network?
 Reduce Redundancy
 Enhance Capabilities
 Share Resources
• Data
• Devices
• Internet
 Communicate

Types of networks
 P2P (Peer-to-Peer)
 Client-Server
Client – a computer that requests
resources from another computer
Server – a computer that provides
resources to other computers and
manages those resources.

Peer to Peer
 Advantages
 Easy to install
 No server needed
 Each user has control
 No administrators
needed
 Less expensive
 Disadvantages
 Security & backups
must be applied
individually
 Many passwords
needed
 Reduced password
security
 Reduced machine
performance
 No central control
 Not flexible (hard to
change things)

Client Server
 Advantages
 Centralized
security &
backups
 Faster access
 Single password
 Better password
security
 Disadvantages
 Central point of
failure
 Administrator
required
 Server and server
software required
More expensive

NOS (Network Operating
System)
 Controls user and application access
to resources
 Restricts user access times and
locations
 Controls communication between
networked computers
 Lets name a few…

NOS (Network Operating
System)
 Microsoft Windows
 Novell Netware
 UNIX
 Linux
 BSD (Berkley Software Distribution)
 Sun Solaris
 IBM OS/2
 Mac OS

Network Scope
 LAN (Local Area Network) – group of
machines in one or many closely
located buildings that are all
connected together with high speed
links.
 MAN (Metropolitan Area Network)
 WAN (Wide Area Network)

Terms
 NIC (Network Interface Card)
 Node – A device that can communicate with
a network. Identified by a unique number.
 Segment – part of a network consisting of a
number of nodes that all use the same
communication type
 Backbone – connects segments together.
 Protocol – the standard for communications
 Topology – the layout of the network

Types of Servers
 DC (Domain Controller)
 File & Print Server
 Communication Server
 Mail Server
 Web Server
 Network Management Server
 Name server (DNS, WINS)
 Addressing server (DHCP)
 Licensing server
 Software distribution server (SMS)
 Backup server
 Patch Management server (SUS)

Skills of the Network
Professional
 Basic Technical skills

configuration
 Network design
 Protocols, topologies, media types
 Other Technical skills
 Security
 Voice & Data integration
 NOS’s indepth
 Network device configuration (Routers…)
 Data warehousing

Association)
CWNP (Certified Wireless Network
Professional) program
 Vendor Certifications
Microsoft, Novell, Oracle, Sun, Cisco

Acronyms
 DC, Domain Controller
 CompTIA, Computing Technology Industry Association
 LAN, Local Area Network
 MAN, Metropolitan Area Network
 WAN, Wide Area Network
 MCSE, Microsoft Certified Systems Engineer
