They also allow for a police department to be connected to a local, county, state, and federal network of criminal justice databases (Computer-Aided Dispatch Software Resources, n.d.).
Typically emergency calls for service are automatically routed to dispatchers. When these calls are received the CAD system will recommend a unit assignment based upon a number of factors. These include: the location of the incident in question, they type of call that it is, and the availability of units for dispatch. Another feature that CAD systems have is to keep an online history of all calls that are taken. This history is usually kept for a six-month time period. This allows the dispatcher to have access to any prior calls regarding specific addresses, which may be helpful for the officer that is responding. It also maintains notes about locations that might contain important information for the officer. An additional helpful feature of the CAD system is that of time stamping. The system time stamps a call when it comes in, when it is assigned, and when it is completed. This helps for reporting purposes when trying to figure out how efficiently a police department is running (McEwen, 2002).
A further feature that a Computer Assisted Dispatch system can have is that of a mapping system. A mapping system can help a dispatcher better locate the source of a call along with helping to determine the best route that can be used to get to the scene. This feature allows for law enforcement dispatchers to obtain quicker response time during emergencies. This feature also includes the use of a GIS or Geographic Information System. This provides the dispatcher with geographical analysis and visual references to use in call dispatch (Computer Aided Dispatch (CAD) System Provides Mission Critical Mapping Capabilities for 911 Call Centers, 2008).
In addition to assisting with the dispatching of emergency calls, a CAD system has other functions as well. It helps by providing dispatchers with the status of all...
It also tracks any other activities that an officer might be engaged in, such as traffic stops. Knowing what officers are available to take calls is very important in being able to run a police department efficiently (Computer Aided Dispatch in Support of Community Policing, 2002).
The strategic and tactical applications of an E911 and CAD system are to facilitate the taking and dispatching of emergency calls. The goal is to have a fast and reliable system in place to assist in handling emergency situations as quickly and efficiently as possible. Having the information that is needed all in one place and easily accessible is the key to handling 911 emergency situations effectively. Encompassing E911 into a good Computer Assisted Dispatch system is the best way to make sure that emergency situations are responded to in a timely fashion and that the help that is needed is received as quickly as possible.

Computer Forensic Tools: The use of computers in homes, schools, offices, and other places has increased in the past few years due to technological developments. As computers have become important components of modern communication, their increased use has also led to the emergence of computer crimes. Computer crimes basically involve the use of a computer system to carry out an illegal activity. In attempts to lessen the frequency and impact of
Computer Science Fundamentals Too often the mechanistic are taken for granted in computer science. The technology has been around long enough now, that many take for granted the great powers that computers and computing technology has afforded modern man and his society. The fundamental characteristics of any successful endeavor should be investigated to help identify a pattern and produce learning and gather information. The purpose of this essay is identify and explain
Assisted suicide is a suicide committed by someone with assistance from someone other than themselves, many times a Physician. Assisted suicide is typically delivered by lethal injection. The drugs are setup and provided to the patient and the patient has the choice as to when they deliver them by pressing a button themselves. This is a controversial topic that has both proponents and opponents for various the reasons. The most
"It's a cheaper option than nursing homes -- daily rates are lower," says Redding. "You pay only for what you need, not for what your neighbor needs." Policymakers do have reason to be wary. If assisted living becomes covered by Medicaid, hundreds of thousands of elderly people might take advantage of it, thereby placing an ever greater demand on scarce government resources (Horvitz 1997). As noted above, Sunrise Assisted Living
This Never-Never Land does not seem recognizable as Vietnam anymore, given how much the nation has changed since the cessation of the conflict. Ironically, Herr's portrait of a world-upside down might seem to better reflect the current situation in Iraq, another nation which is torn apart by a confusing array of factions and bloody violence. Of course the terrain, nature of the fighting, and the ideological issues at stake are
In addition statistics indicate that many of those who apply and are hired do not make it though the training for the job. This provides evidence of importance when it comes to choosing the right candidates to begin with so that those who are hired are more capable of making it through the training. According to Furey newly hired dispatchers are also affected by the attitudes of the dispatchers already working therefore
