Began with launch of Sputnik in USSR President Eisenhower wanted to bring US back to arms race lead created the Advanced Research Project Agency (ARPA) Second head: Lawrence Robert • Wanted to build network system • Used idea of packet switching developed by Paul Baran at RAND • 1969: Created a special computer called the Interface Message Processor which could used the ARPANET (first internet)
First ARPANET protocol was Network Control Program • Later Replaced by Internet Protocol (IP) When ARPANET retired in 1990, it was transferred to the National Science Foundations NSFNET • Connected with research facilities in Europe • Established what is today’s internet
Most common used through the World Wide Web (WWW) • A Database in the form of WebPages that can be search through web browsers Contain URL’s or Uniform Resource Locators used to located different WebPages on the WWW Uses Hypertext in order to quickly navigate from on WebPage to another • A hypertext is a link to another Webpage • Term was coined by Ted Nelson in his book “Literary Machines”
The World Wide Web is made public through Internet Service Providers (ISP) • Company that provides internet services (web browsers) • Ex: Internet Explorer, Mozilla Firefox ISP use IP Addresses to locate and transmit information located on the Internet
A code that defines where a certain piece of information is located on the internet when using an ISP • Usually four sets of numbers separated by a “.” • Numbers can range from 0- 255 an example of an IP address would be 220.127.116.11
Domains are ways to locate IP addresses without needing to know the IP address itself This is done by giving a name to a specific Webpage in order to locate it • Ex: www.bxscience.edu Make browsing the internet a lot more convenient and quicker Domains are split into 3 levels
Top-level includes the end of the web address • www.bxscience.edu There are many top-level domains in a web address • .com- for commercial purpose • .edu- from educational institutions • .gov- provided by the government • .org- provided by a nonprofit organization
The second level of a domain includes the middle portion along with the end portion of the web address • www.bxscience.edu The third level of a domain includes the who web address • www.bxscience.edu
A software program that searches the internet for information though the use of key words Popular Search engines include • www.google.com • www.yahoo.com Search engines can be used to learn more about the different fields of forensic science
Currently the most popular service on the internet Works similar to conventional mail except a lot faster An email is transmitted using an email address • An email address includes a name, word, or phrase that identifies who the email is being sent to followed by an “@” along with the internet webpage address that provides the email service • Ex: firstname.lastname@example.org Makes forensic scientist communicate and exchange information a lot faster
The analysis of events on the internet that can be used to solve a crime Analyze recent activity on the internet even if the internet history has been deleted This is done through Windows Sap Files • Data created while on the internet and deleted when getting offline • Deleted data is stored in an erased file on the computer
Forensic Scientist locate and analyze the deleted data on the internet from these files Also look at recent emails and bookmarks for possible evidence for the crime
Hacking is the unauthorized intrusion of computers and the internet It is considered to be a felony in the United States Hackers are able to do what ever they please on the internet as long as the computer they hack remains online Forensic Scientists track hackers by finding their IP addresses
