HFTPWAN
Connections type and speed: ISDN (128Kbs)- Integrated Services Digital
Network offers the lowest overall circuit cost type of
service for connection of remote network sites to a central location.
T1* (1.5Mbps) and T3* (up to 45Mbps) The standard speed is NOT 100Mbps.
NOT Associated Technologies NIC’s, Repeaters, Hubs & Apple Talk
* These are U.S. centric terms

HFTPNetwork Security
Network Login and Passwords Promptly change your password on initial
login for proper security procedures for user-level passwords
Single Sign-on Components of a single sign-on system
include authentication and a directory service.
HFTPNetwork Security
PGP - Pretty Good Privacy Software that implements public key
cryptology that requires a key pair of both a public key and a private key
SSL – Secure Socket Layer Is built upon Public key encryption, Digital
Signature, and Digital Certificates, but NOT Single Key system using substitution encryption.
To defeat SSL and PGP you would utilize Cryptanalysis, Reverse engineer of the implementation, and Pass phrase attack, but NOT insider security information.

HFTPNetwork Security
SNMP – Simple Network Management Protocol
an application layer protocol that facilitates the exchange of management information between network devices.
Network File Access controls security rights for users files
Biometric Technology Is capable of enhancing physical security
such as guest and employee entry.
HFTPFirewalls
Software and hardware that filters and secures
your private network, allowing only authorized
access and transmissions of your internal data.
HFTP
Malicious computer programs: Virus Unauthorized set of programmed code that
attaches itself to other programs. Worm Independent programs that may replicate itself
throughout the network. Trojan Horse Masquerades as a legitimate program but has
malicious software inside
Are computer bugs a virus??
Computer Viruses

Poll
HFTPTCP/IP
TCP/IP – Transmission Control Protocol/Internet Protocol Is NOT a telecommunication communications protocol.
TCP Packets: Are numbered so they can be reassembled in the correct sequence
at the destination. Are transmitted over the network as capacity becomes available. Forwarded across the network separately and do not necessarily
follow the same route. Do not contain destination addresses only. Header information includes
Total length of the packet, destination IP address, Source IP address, and Error checking information. DOES NOT include sender’s login information.
HFTPTCP/IP
Packet Switching Checking for valid packets, destination address, best
route, assembling packets in order, but NOT for data compression.
Static verses Dynamic Addresses DHCP: Dynamic Host Configuration Protocol is used
to assign dynamic IP addresses on an as-requested basis.
3 Classes of IP Addresses
HFTPIP Address Classes
Class A ###. xxx .xxx . xxx (ex. 26.x.x.x)
(1-126).(1-254).(1-254).(1-254)
Class B ### .###.xxx .xxx (ex. 172.16.x.x)
(128-191).(1-254).(1-254).(1-254)
Class C ### .###.###.xxx (ex. 192.168.1.x)
(192-223).(1-254).(1-254).(1-254)
IP Classes
HFTPParallel Transmission
Multiple channels to transmit several bits of data at a time
Timed pulses sent on other wires within the same cable to coordinate the flow of data
Parallel ports, parallel cable, user configuration of controller
Over short distances -LAN
HFTPSerial Transmission
Single channel to transmit bit by bit
Bits travel as a sequence over a single wire with start and stop bits to coordinate data flow
Serial cable, serial ports, user configuration of controller
Long distances - telephone transmission
HFTPModems
Converts on and off digital pulses of computer data into on-and-off analog tones that can be transmitted over a normal telephone circuit.
Uses:
Allow computers to communicate over distances
E-mail, internet, bulletin boards
Polling, file transfer, system support

Bluetooth Distance Limitations 30 feet (10 meters)
New Technology Communications between
any electrically powered device or appliance
HFTPVPN – Virtual Private Network
Allow for secure connections that “tunnel” through the Internet to connect 2 private LAN’s or Computers, which reduces costs overall.
HFTPVoIP – Voice over Internet Protocol
Set of facilities used to manage the delivery of voice information over the Internet. VoIP involves sending voice information in digital form in discrete packets rather than by using the traditional circuit-committed protocols of the public switched telephone network
HFTP
HSIA – High Speed Internet Access Acceptable methods for providing HSIA
service to guest rooms: Wireless proximity Telephone network Electrical wiring system Cable system
HFTP
Bandwidth DSL ISDN Frame-relay T-1 T-3: OC-3/DS-3
HFTPASP – Application Service Provider
Is the server model in which hardware is housed and maintained off-site, yet users can access the application and data via a web-based Internet connection.
HFTPTelephone Switches
Trunking Trunk lines are defined as a telecommunications
line between 2 switching systems. Incoming call routing Uses caller ID Automatic Number Identification
(ANI) information to retrieve customer records from a database and send the records and call to a specific call center operator.
DeMarc The point where responsibility for telecom services
into a building transfers from the carrier to the end user organization.
HFTPTelephone Switches
Voice over IP Place voice and fax calls over internet
connections. Does not provide HSIA or In-room internet connectivity, hotel operators to receive free telephone services.
Automated Call Distributor (ACD) Useful for Reservations, PBX and Room Service
departments. ACDs would not be used to automatically generate
Express Checkout reports. Automatic check out is not a function of a
PBX system.
HFTP
Guest Room Telephones Features that may be included Data port sets 2 line capability ADA hearing impaired feature handset Hands free speaker phone capability One button dialing and redialing
HFTPDatabase Management Software
Allow users to catalog and store information for future use
Collection of related facts and figures designed to serve a specific purpose
Possible Uses: Preparing mailing lists for marketing and
promotional activities. Help managers sort through personnel records to
identify performance review dates for employees that correspond to the dates on which they were hired
HFTP
Database StructuresFiles organized in ways that facilitate
searching for data, updating data, and generating accurate, timely and useful reports for management.
HFTPFiles, Records, and Fields
Files “THE” Database i.e... Inventory, purchases, suppliers
Records individual information contains “key” field
Fields identified by type of info. Text, Calculated, Logical, Date, etc.
HFTPDatabase Structures
Hierarchical Resembles that of the root of a tree
Arranges Files, Records, and Fields Master Records and Subordinate Records Data inherit attributes, or rights, from it’s parent
Relational Tables are related to each other through key field
Tabular Structure Data appears only once and not replicated multiple times
Flat One Large Table (Flat File) Files are stand-alone collections of data.
HFTPData Management Concepts
Data Warehouse Collection of data from different sources Provides input for decision making The repository of all data Data is received and stored following specific validation rules
Data Mart Separate database designed for specific group of users
(e.g. marketing, group sales, etc.) Data is extracted from Data Warehouse to
protect its integrity
Data Mining Statistical and rule-based reasoning to find
patterns in data (e.g. forecasting occupancy) Should be performed against the Data Mart
HFTPOther Terms
File Server - Computer that controls the flow of information along a network and stores files created by application programs, has large storage hard drive with space to share, and provides the capability to simultaneously access the same file.
Application server - Enables several users to offload specialized tasks onto a shared computer.
Secondary storage devices - Refers to Hard drives, CD-RW, DVD-RW, Zip Disks, Removable storage devices, but NOT RAM.
High Availability - Options include Multi-processors, disk arrays, redundant power supplies, but NOT Spare Memory Modules.
