Course Content

Introduction to Networking Technology

The makeup of a network, reasons for networking systems, the servers function, the clients function, peer-to-peer networks, client-server networks, network operating systems, the directory services of the major NOSs, network adapters, network cables, cable-less connections, local area networks (LANs), wide area networks (WANs).

The Layout And Access Control Of A Network

Topology and contention methods, bus, star, ring, mesh, combinations of these,

Carrier-Sensed Multiple Access with Collision Detection, token passing and demand priority.

Fault tolerance and High Availability

Disk mirroring, duplexing, striping, volumes and tape backup.

The OSI 7 layer model

• The seven layers of the OSI model,

• The physical layer, NICs, hubs, switching hubs, MAUs, repeaters, transceivers

• The Data Link Layer, bridges, the 802 specs, MAC addresses

• The Network Layer, routers, differences between routers and routers, routable and non-routable protocols, static and dynamic routing, default gateways, unique network Ids.

• The Transport Layer, connectionless and connection transport, the purpose of name resolution.

• Expanding a Network, reasons for expanding a network, gateways.

Network Protocols

How computers communicate, what is a Protocol? NetBEUI, IPX/SPX, TCP/IP

Remote Connectivity

Reasons for using remote connectivity, PPP and SLIP, Public Switched Telephone Network (PSTN), Point-to-point Tunnelling Protocol (PPTP), X.25, Frame Relay, Asynchronous Transfer Mode (ATM), Integrated Services Digital Network (ISDN)Asymmetric Digital Subscriber Line (ADSL), configuring a modem.

TCP/IP Addressing

Comparing TCP/IP addresses with telephone numbers, examining a sample IP address, how a computer views an IP address, why classes of addresses were introduced, class A, B and C addresses, standard subnet masks, how routing works, IP addressing rules, how CIDR works, manually and automatically configuring IP addresses, port number usage.

TCP/IP Host Names

Why host names are used, different types of host names, resolving names with host files, resolving names with DNS and WINS.

TCP/IP Protocol Suite and Utilities

TCP/IP network architecture, TCP and UDP, IP and ARP, ICMP and IGMP, utilities for testing a TCP/IP network, utilities for using a TCP/IP network.

Basic Network Security

User and share level file system security, standard password procedures, data encryption, firewalls and Consoles.
