Premium Internet Protocol Suite OSI model Transmission Control Protocol
TCP/IP for IP version 4 (IPv4) is a networking protocol suite that Microsoft Windows uses to communicate over the internet with other computers. It interacts with Windows naming services like DNS and security technologies‚ such as IPsec primarily‚ as these help facilitate the successful and secure transfer of IP packets between machines. Ideally‚ TCP/IP is used whenever Windows-based computers communicate over networks. This subject describes the components of the TCP/IP Protocol Suite‚ the protocol
Premium IP address Transmission Control Protocol
Transmission Control Protocol (TCP) and Internet Protocol (IP) are the two main protocols that the internet uses. A protocol is a rule that governs how data moves through the internet and how network connections are established and terminated. TCP/IP‚ as it is commonly called addresses separate issues that allow the use of the internet. They complement each other. TCP is in control of accurate delivery of a message. How does this happen? First it controls the disassembly of the message or file

An IPv6 address is 128 bits rather than the 32 bits in an IPv4 address. This length increases the number of possible addresses from about 4 billion in IPv4 to 3.4 x 1038 addresses (that’s 34 followed by 37 zeros!) in IPv6. Unless IP addresses are assigned to every star in the universe‚

Networking Topologies and TCP/IP protocol Bus Topology It just doesn’t get much simpler than the physical bus topology when it comes to connecting nodes on a Local Area Network (LAN). The most common implementation of a linear bus topology is IEEE 802.3 Ethernet. All devices in a bus topology are connected to a single cable called the bus‚ backbone‚ or ether. The transmission medium has a physical beginning and an end. All connections must be terminated with a resistor to keep data transmissions

The main benefits of the OSI model include the following: • Helps users understand the big picture of networking • Helps users understand how hardware and software elements function together • Makes troubleshooting easier by separating networks into manageable pieces • Defines terms that networking professionals can use to compare basic functional relationships on different networks • Helps users understand new technologies as they are developed • Aids in interpreting vendor explanations of product

of an IP address does which of the following? The subnet mask defines network and host portions of an IP address. 3. If a protocol is routable‚ which TCP/IP layer does it operate at? A routable protocol operates at the Internetwork layer of TCP/IP. 4. Which of the following is a private IP address and can’t be routed across the Internet? The IP address 172.19.243.254 falls within one of the IP address ranges reserved for private uses by Internet standards groups. 5. Which TCP/IP model

Exercise 2 LAB REPORT Q:What is the default directory when you open a new command window? What is your working directory? A: /home/guest/ /home/guest/fangyuliu Exercise 3 LAB REPORT Q:Is the Internet service daemon‚ xinetd‚ started in your system? Is inetd started in your system? Why? A:xinetd(extended Internet daemon) is started in my system rather than inetd (internet service daemon). Both of them are super-server daemon started only under request. Because xinetd is more secure than

TCP/IP LAN Check Point #8 Answer: C Explanation: The network address 150.50.0.0 that was originally assigned is a class B‚ so it has a default subnet mask of 255.255.0.0. Then you need to divide this network into 7 subnets and only the net work address 255.255.240.0 provides enough networks because it will provide 16 - 2 = 14 subnets (-1 for the network address and -1 for the broadcast address‚ which gives a -2 from the total of subnets). #9 Answer: C Explanation: The network address 209
