the 1960s and 1970s, the US Department of Defense funded programs where computer scientists were paid to develop Internet protocols. The evolution of the Internet continued in the early 1980s when the National Science Foundation funded a program at many colleges and universities aimed at creating connected computer networks across the United States. Electronic mail and instant messaging joined the WWW as part of the public "Internet" in the mid-1990s. 2. What is the World Wide Web (WWW)?
TCP is the transport layer protocol that links the application layer to the network layer. TCP breaks the data into smaller packets, numbers the packets, ensures each packet is reliably delivered, and puts the packets in the proper order at the destination. IP is the network layer protocol and performs addressing and routing. IP software is used at each of the computers through which the message passes through; IP routes the message to the final destination. TCP/IP is the transport & network layer protocol used on the Internet.
The remaining 28 bits are used for individual IP multicast addresses (Shimonski & Alpern, 2009). RFC 1918 is a standard that reserves several addresses within each of the classes A, B, and C and are commonly used for home,
Microsoft was formed as a partnership in 1975 by Bill Gates and Paul Allen, they started out as a small company and they envisioned that every home would eventually have a desktop computer (Microsoft, 2013). Little did they know how their little company would “take off” and revolutionize the world of computers and help put computers in virtually every home and business. Microsoft has even reached out globally, I have seen versions of windows in a third world country where there is barely any infrastructure. Although it was an older version of windows than what we use today it is still windows none-the-less. Gates and Allen’s vision starts to become a reality in 1980 when they enlist Steve Ballmer to help run the company.
Steven Michael Stepien TB143 Week 2 6/25/2011 HISTORY OF INTEL CPUs USED IN PCs That was the year Intel created the 8086, a 3-micron chip chugging along at 4.77MHz, while later versions would run at up to 10MHz. The 8086 had just 29,000 transistors, which was still nearly four times as many as the 8085 released in 1976, and was Intel's first 16-bit microprocessor and responsible for kicking off the 16-bit era (note that the 8086 wasn't the first 16-bit chip). Backwards compatibility with software written for the 8008, 8080, and 8085, and the ability to address 1MB of memory natively made the 8086 a near instant success. Intel entertained the computing world with the 80286 in 1982, a 1.5-micron part with a mind-boggling 134,000 transistors and 16MB of addressable memory. The first 286 pedaled along at 6MHz and, like the original 8086, would later double in speed.
Background The FBI first sought to embrace technology in the 1980s during the onset of computer availability and hoped to have a paperless office where agents could quickly pull up case files, information, and photographs at the comfort of their desks without having to sift and sort through numerous paper files. The infrastructure in that time was limited to text based search engines and there were no provisions for photo storage or the ability to scan written reports. As a result, the FBI found its agents decided not to rely on the existing technology and were reverting back to paper. After the attacks on September 11, 2001, the FBI was placed under scrutiny for being ineffective and inefficient in its operations due to the time it would take to share information with other law enforcement agencies, locate reports, and transmit them from one location to another (usually done via fax or by mailed CDs). To combat this, the FBI developed a plan known as Trilogy, which aimed for three primary goals: A new computer network, personal computers for most agents, and an online criminal database that would be titled Virtual Case File (VCF).
There are 4 residence halls that house a total of 2,000 students. Suppose the university has the 128.100.xxx.xxx address range on the Internet. How would you assign the IP addresses to the various subnets? How would you control the process by which IP addresses are assigned to individual computers? You will have to make some assumptions to answer both questions, so be sure to state your assumptions.
10.10.0.10 Question 12 What value is configured in the DNS Servers: line? 10.10.0.10 Question 13 What is the default location for DHCP server backups? C:\windows\system32\DHCP\co-occurrence\ Question 14 What IP address is configured on the SEA-SVR2computer? 169.254.209.252 Question 15 What appears in the IP address text box? 10.10.0.55 Question 16 From which DHCP server are you receiving an IP address?
You are a consultant working on a site plan for a medium-sized organization. The organization consists of a main office and three branch offices. Two of the locations have standard IP links to the main office, while the third branch office is a separate domain and uses an Internet connection for e-mail. How should you configure the site links for the three branch offices to the main office? A: RPC over IP for the two standard link branch offices and use SMTP for the remote site.
Did the targeted IP host respond to the ICMP echo- request packet with an ICMP echo- reply packet? If yes, how many ICMP echo- request packets were sent back to the IP source? Yes, the targeted IP host did respond to the ICMP echo request packet.There was a total of 8 packets. 6. Find a TCP three- way handshake for a Telnet, FTP, or SSH session.
