Windows NT security summary :: essays research papers

Winders NT Security NT was introduced in 1993 and quickly became a popular platform for client-server environments. NT is based on 32-bit architecture so it provides many features like multi-tasking, resource sharing and high availability of resources. NT provides increased security over older operating systems like Windows 9x and UNIX.   Ã‚  Ã‚  Ã‚  Ã‚  NT has both server and client versions. The client version of NT does not have as many features or capability. The Server version can handle 256 connections while client version can only do one. Global security management functions are not supported by client version either.   Ã‚  Ã‚  Ã‚  Ã‚  NT gives an administrator the ability to control user accounts and groups. Domains are used to contain machines in groups. This can be used as an administrative tool to control users privileges and access to system resources and data. It can also be useful for updating and stuff like that. One machine in a domain is set as the controlling system and from that machine a security policy can be created and enforced on the entire domain. Backup domain controllers are recommended. Machines on a domain share a user database which allows a user to have a single ID and easily sign on to any machine as long as its in the domain. NT uses the ideal of trusted domains. If a user authenticates to his primary domain, he is free to access any other sub domains as long as that domain trusts the primary domain. (Pass through validation) Domain trusting allows for a user who does not have an ID on a given domain to still gain access to it as long as the user is validated on the primary domain, however, what permissions the user has is dictated by the Admin of the domain he is a guest in. Domains make it easier to control users, machines, and what goes on. It is useful in enforcing policies on groups and restricting the rights of users. Security issues are minimized in remoter applications because there is no need for someone at each site to be in charge of security and policy enforcement. One Admin can group remote sites into their individual domains and provide increased security from his desk. User accounts come in both local and Domain flavors. This means a user can be restricted to using only the local machine or any machine on the domain. NT has a guest account, recommended password protecting it.

Lexington and Concord: Who Fired First? Essay

The purpose of this Essay is to investigate and state my opinion on who fired first at the Battle of Lexington and Concord. As for every story, there are two sides to this important timepiece. There are many sources of information for this subject. Many provided for me were affidavits, or accounts, of key people in the conflict. Some are more credible than others. As for the affidavit of John Parker, it seems believable. On the other hand, it lacks detail. His account is very short and simple. Not many details are present compared to others. In this legal document, he states he ordered them to disperse and to not fire upon the enemy (British Troops). According to him, the British troops approached and rushed with fury and fired without any previous provocations. In my opinion, this may seem like a good source, but when compared to others it is not the greatest. I believe that the affidavit of Edward Thoroton Gould is the second to the last most credible group of statements of the six pieces of evidence/ information that were given to me. He testified that on April 18th of 1775, he embarked with the light infantry and grenadiers of the line commanded by Colonel Smith, proceeding to Lexington. â€Å"On our arrival at that place, we saw a Body of provincial troops armed, to the number of about sixty or seventy Men; on our approach, they dispersed, and soon after firing began, but which party fired first, i cannot exactly say, as our troops rush’d on shouting , and huzzaing, previous to the firing, which was continued by our troops, so long as any of the provincials were to be seen.† As you can see, Edward Thoroton Gould is very clear and detailed in his description. He seems to know what he is talking about, and has no doubts that it happened that way. Simon Winship of Lexington speaks for the opposing side of Edward Thoroton Gou ld. They are both clear and detailed, and have well-written descriptions. He was passing the public road in Lexington, peaceably and unarmed, when he was met by a Body of the Kings regular  Troops. Also being asked to dismount, he was forced after asking why. Ordered to march in the midst of the Body, he was being examined as to whether he was or was going to warn the Minute Men. He came within about an eighth of a mile of the meeting-house, when he saw an officer commanding his troops to halt, prime and load their firearms. They marched a little further, within a few rods of Captain Parkers Company , when Winship â€Å"observed an Officer at the head of said troops, flourishing his sword, and with a loud voice, giving the word fire!† If Winship is honest, this is the most believable story. He even has the details of the word â€Å"Fire!’† being said. He declares in the most solemn manner that there was no discharge of arms until the word fire was given by the British Officer. In the diary of British Officer Lt. John Barker, he makes the most detailed description of what happened ikn his eyes. Since this is a diary/primary source, this may be the most credible for me to believe. According to him at 2 o’clock they began marching through a very long ford up to their middles, where they took 3 or 4 people who were going to give intelligience. â€Å"About 5 miles on this side of a town called Lexington, which lay in our road, we heard there were some hundreds of people collected together intending to oppose us and stop our going on. At 5 o’clock we arrived there and saw a number of people, I believe 2 and 3 hundred, formed on a common in the middle of the town; we still continued advancing, keeping prepared against an attack tho’ without intending to attack them, but on our coming near them they fired one or two shots, upon which our men without any orders rushed in upon them, fired and put ‘em to flight.† Their missioon was to destroy a magazine of stores collected in Concord. Of all the legal documents, the diary entry of British Officer Lt. John Barker is the most credible. Bits and pieces of all the affidavits could be true, but as a whole piece the diary entry in my belief is the best. The reason for this is because it is a actual written entry, and has the greatest of details. The colonial troops fired first, in my opinion. Only someone who experienced it firsthand and documented it could have given that credible piece of evidence. He even stated that were actually a few people trying to sneak intelligience, otherwise stated by Simon Winship. This is my opinion of who fired first at The Battle of Lexington and Concord.

Gallons to Liters - Unit Conversion Example Problem

This example problem demonstrates how to convert gallons to liters. Gallons and liters are two common units of volume. The liter is the metric volume unit, while the gallon is the English unit. However, the American gallon and the British gallon are not the same!  The gallon used in the United States  is equal to exactly 231 cubic inches or 3.785411784 liters. The  Imperial  gallon or UK gallon is equal to approximately 277.42 cubic inches. If youre asked to perform the conversion, make sure you know which country its for or you wont get the correct answer. This example uses the American gallon, but the set-up for the problem works the same for the Imperial gallon (just using 277.42 instead of 3.785). Key Takeaways: Gallons to Liters The unit conversion between (American) gallons and liters is 1 gallon 3.785 liters.British and American gallons are not the same. The American gallon is a smaller unit of volume and has a different conversion factor.There are about four liters per gallon. Gallons to Liters Problem What is the volume of a 5 gallon bucket in liters? Solution 1 gallon 3.785 liters Set up the conversion so the desired unit will be cancelled out. In this case, we want liters to be the remaining unit. volume in L (volume in gal) x (3.785 L/1 gal) volume in L (5 x 3.785) L volume in L 18.925 L In other word, there are about 4x more liters when you convert from gallons. Answer A 5 gallon bucket contains 18.925 liters. Liters to Gallon Conversion You can use the same conversion factor to convert liters to gallons or you can use: 1 liter 0.264 US gallons To find how many gallons are in 4 liters, for example: gallons 4 liters x 0.264 gallons/liter The liters cancel out, leaving the gallon unit: 4 liters 1.056 gallons Keep this in mind: there are about 4 liters per US gallon.
