Read-only memory is computer memory on which data has been prerecorded. Once data has been written onto a ROM chip, it cannot be removed and can only be read. The POST beep codes make troubleshooting a computer start-up problem easier because without the codes a user would not know what was wrong with computer. There are so many different problems that can occur when your computer breaks down. Having beep codes to help decipher the problem makes the repairs easier.
Viruses and Worms Operating system security is at the core of a safe, secure operating system. Our computers are vulnerable to corrupt files, compromised data, and system crashes. There are many attack methods used to uncover your personal information. Two of the methods are viruses and worms. A virus is an executable code usually sent in an e-mail attachment or hidden in audio clip, video clip, or game.

Almost any system administrator of a large network has been probed more than once before. Network probes are technically not infringements themselves, they should not be taken lightly they could lead to actual invasions in the future. There is a saying better be safe than sorry. The most commonly use network probe is the port scan. A port scan is a technique used by intruders to discover the services running on the object machine.
Case Study Week 1 Katherine Vega DeVry University SEC 280 Ahmed Azam November 4, 2012 Ping Sweeps and Port scans are related programs or tools, called network probes, which allows a person to not only gain access to online computers, but also to determine what services are being run on them furthermore to get an edge on compromising information. This network probes aren’t inherently malicious on their own as they are used by network administrators for the aforementioned diagnostics, however in the wrong hands they could pose a security threat. This is not meant to cause fear but to bring about awareness to computer users. As the programs are most commonly used for network diagnostic and determining other network problems. To begin

To be clear, it is not acceptable to copy and paste sentences or a paragraph or more into a student paper, and then include an intext citation to the source at the end of the copied material. The objective of papers for the class is to develop student awareness of the content and to improve student ability to think and present material about fraud cases in a professional way. Use of the student’s own wording and explanations is very beneficial. That is the

Officers should gather intelligence and conduct surveillance. Intelligence like what kind of computer is being used, where is the house, name of internet provider what time of software, what is the user name and password? Any information related to the interior of the residence is also helpful, not only at the time of writing the affidavit but especially at time of execution, so the proper tactics can be used when making entry. These questions can reveal valuable information and provide additional leads that would be beneficial to the search team and forensic examiner, saving both time and effort while preserving evidence.
