What are the different levels of RAID, and what does each do? List at least four different levels with one advantages and disadvantage of each. 2. (10 Points) List the six basic functions of a network operating system. 3. (10 Points) How is a hub similar to a switch? How are they different? Explain briefly. 4. (30 points) Do a web search and list the main responsibility (function) of the following protocols. Also, mention on which layer of the TCP/IP protocol stack following protocols operate. a. IP IP (Internet Protocol) works at the network layer. IP prepares a packet for transmission across the internet. It handles addressing, data encapsulation, fragmentation and reassembly, and routing. b. UDP c. TCP d. ARP e. DHCP f. NAT g. ICMP h. SMTP i. POP3 j. IMAP T 5. (10 points) Do a web search and list the main function of: a. Telnet Telnet is a protocol that allows you to connect to remote computers (called hosts) over a TCP/IP network (such as the internet). Using telnet client software on your computer, you can make a connection to a telnet server (that is, the remote host). b. FTP c. DNS d. Listserv e. VoIP 6. (10 points) What is the difference between IPv4 and IPv6? Write at least four differences. 7. (20 points) One of the addresses in a block is 192.168.32.1/24. Find the number of host addresses available in the network, network mask, the first address, and the last address. Show your work. What are the different levels of RAID, and what does each do?
