Domains are groups of PCs on the same network and also a method to isolate communications between the members in the domain and the other data traffic. A domain controller is a device used to organize and control a domain environment. A domain controller makes use of an active directory to organize all user account in the domain. An frankenstein active directory is a microsoft technology, part of Active platform, which enables applications to find, use, and manage directory resources (such as user names, network printers, and permissions) in a distributed computing environment.

Diagram of a ka-band-Solid-Dish-Antenna.1 isa server/proxy server/gateway the isa server also acts as a proxy server/gateway. A proxy server is a server that acts as an intermediary between a workstation user and the Internet so that the enterprise can ensure security, administrative control, and caching service. A proxy server is associated with or part of a gateway server that separates the enterprise network from the outside network and a firewall server that protects the enterprise network from outside intrusion. An advantage of a proxy server is that its cache can serve all users. If one or more Internet sites are frequently requested, these are likely to be in the proxy's cache, which will improve user response time. A proxy can also do logging. A user on a workstation which is connected to the domain can only view the internet if the address and port number of the isa server is set in the proxy address and port settings. 13.0 how to set the proxy settings: step 1: Click tools then click internet options on the browser. step 2: Click on the connection tab and then click lan settings.
It is mainly used to transmit fm audio services and in social and business network projects. The band requires ku-band lnbf, coaxial cable, and a c/Ku band feed horn antenna. Rg-6 is the perfect coaxial cable for transmission. Diagram of a ku-band-Solid-Dish-Antenna.0 essay ka band Kurtz Above or ka band requires more power to transmit signals. The downlink frequency range.3.2 ghz while uplink frequency range.5 to 31 ghz. The size of the dish for this band is even smaller than C band. It varies from two feet to five feet. It is used extensively in military airplanes and vehicle speed detection.
C band dishes are large in size approximately 6-7feet. Diagram showing C-band dish Antenna.0 ku band ku band or Kurtz Under band is used to transmit signals at high frequencies. The downlink frequency of the band ranges from.7.7 ghz while uplink frequency ranges from 14.5 ghz. Nbc started its transmission services on this band in 1983. The dvb or Digital Video broadcasting service utilizes this band. The north American satellites broadcast ku band signals because they operate in the same range of downlink and uplink frequency. The band consumes more power than c band due to additional data transfers. It also requires 16 to 24 transponders used for broadcasting satellite service.

As for killer wireless connection, a wireless router or access point is placed at every passage way in each building. The wireless access point is either connected to one of the switches in the cabinet or the main 24-port switch. Public port Private port building 1 cabinet lan port workstation image of server for ncaas headquarter image of antivirus server for ncaas headquarter.0 desciption of devices used in ncaa network.1 satellite dish and frequency band ncaa uses a ku-band (Kurtz under band) satellite. Vsat is the equipment used to uplink and downlink using either c, ka or ku band. There are various types of frequency bands, the three primary bands are listed below: C-band Ka-band Ku-band.2 c band c band is the oldest and most frequently used frequency for sending signals to satellite dishes.
The c band consumes.7.2 ghz for sending the signals to earth stations (known as downlink) and.9.4 ghz for vice versa (known as uplink). This frequency band has been found to operate under extreme weather conditions as well. It has been divided into 6 subcategories known as Extended c-band, super Extended, insat, palapa, russian, and lmi band. The band requires business large size prime-focal dishes commonly known as bud to operate. The dishes vary between three feet to nine feet. The band will require specific c-band lnbf (Local noise Block feed). It is mainly used to transmit older channels that operate on this band.
This satellite dish receiver is connected to the private port of the internet modem then the public port of the modem is connected to the isa server which acts as the gateway to internet access. The isa server is connected to a domain controller which controls the domain environment by granting anyone who has a registered account on the domain access to the internet recourse. Anyone who does not have an account or valid log on credentials cannot use the internet. Domain controller can also be used to control the network environment by restricting the rights to chance setting on the workstation so that only administrative rights can alter settings. The isa server is also connected to an antivirus server which monitors the automatic updates and downloading of update for all workstation in the domain with a specific antivirus used for the network installed on them.
The isa server is also connected to a 24 port switch which is connected to the different switch cabinet in each directorate of office buildings (since it is a 24 port switch it take a maximum of 23 directorates, another switch can be connected. Ever building has a cabinet where lan (local area network) connections are distributed to different offices. The cabinet comprises of switches and patch panels. The patch panel is a device that is used as a repeater so that signals dont get loss over a long cable. One of the cables that comes from the main 24 port switch goes to the patch panel then a rj-45 cable is connected from the patch panel to the switch (mostly a 24-port switch) in the cabinet (in case of two switches we have two. The patch panel then distributes the connection in the office or to other offices in the building as lan port where workstations can be connected to by the use of rj-45 cable (workstations can also be connected directly to the switch).

Domains are groups of PCs on the same network and are a method to isolate communications between the members in the domain and the other data traffic. Anyone in a domain can communicate with each other and out bound, however PCs not universities defined in the domain can not communicate with those in the domain. Basically the network starts from when the satellite in space sends radio signals down to the satellite dish receiver (ku-band, ka-band, c-band.
