For the given IP address with subnet, identify the number of subnet, the valid host IP addresses for the given problem. Network address : 195.223.50.0 Number of usable hosts needed : 45 Address Class : ---------------- Number of host bits borrowed : ------------------------------ Default Subnet mask : ------------------------------- Custom subnet mask : ------------------------------- Total number of subnets : ------------------------------- Total number of host addresses : ------------------------------- Number of usable address : ------------------------------- i. What is the 2 nd subnet range? ii. What is the subnet number for the 2nd subnet? iii. What is the broadcast address of the 4 th subnet? iv. What are the assignable addresses for the 3rd subnet?

Printers, Inc. is redesigning the network that connects its three locations. The administrator gave the networking team 192.168.11.0 to use for addressing the entire network. After subnetting the address, the team is ready to assign the addresses. The administrator plans to configure IP subnet-zero. As a member of the networking team, you must address the network and at the same time conserve unused address for future growth. With those goals in mind, choose the host addresses on the left to the correct router interface. All the routers interfaces are given below and one of the routers is partially configured. Not all of the host address on the left are necessary.As a computer user, how would you strengthen user authentication? The router interfaces are: Inkjet Fa 0/0 IP : Laser Fa 0/0 IP: Spooler Fa 0/0 IP: Inkjet S0/0 IP: 

Provide the subnet, broadcast address and the valid host ranges for each of the following. i. 172.16.10.65/26 ii. 172.16.10.33/27 iii. 192.168.100.25/30 iv. 192.168.13.40/28 v. 200.10.40.23/25

Your organization network diagram is shown in the figure below. Your company has the class C address range of 199.11.33.0. You need to subnet the address into three subnets and make the best use of the available address space. Which of the following represents the address scheme you would apply to the New York office and Toronto Office?(A) 199.11.33.160/31 (B) 199.11.33.0/25 (C) 199.11.33.128/27 (D) 199.11.33.0/31 (E) 199.11.33.160/30 (F) 199.11.33.128/28

Provide the subnet, broadcast address and the valid host ranges for each of the following. i. 172.16.10.65/26 ii. 172.16.10.33/27 iii. 192.168.100.25/30 iv. 192.168.13.40/28 v. 200.10.40.23/25

1. For each IPv4 network prefix given (with length), identify which of the subsequent IPv4 addresses are part of the same subnet.

(a). 10.0.130.0/23: 10.0.130.23, 10.0.129.1, 10.0.131.12, 10.0.132.7

(b). 10.0.132.0/22: 10.0.130.23, 10.0.135.1, 10.0.134.12, 10.0.136.7

(c). 10.0.64.0/18: 10.0.65.13, 10.0.32.4, 10.0.127.3, 10.0.128.4

(d). 10.0.168.0/21: 10.0.166.1, 10.0.170.3, 10.0.174.5, 10.0.177.7

(e). 10.0.0.64/26: 10.0.0.125, 10.0.0.66, 10.0.0.130, 10.0.0.62

2. Convert the following subnet masks to /k notation, and vice-versa:

(a). 255.255.240.0

(b). 255.255.248.0

(c). 255.255.255.192

(d). /20

(e). /22

(f). /27

3. Suppose an Ethernet packet represents a TCP acknowledgment; that is, the packet contains an IPv4 header with no options and a 20-byte TCP header but nothing else. Is the IPv4 packet here smaller than the Ethernet minimum packet size, and, if so, by how much? What if the packet is IPv6 with no extension headers?

1. Explain cache coherency. 
2. What is the benefit of using sparse addresses in virtual memory?
3. Name and describe the different states that a process can exist in at any given time.
4. Describe two general approaches to load balancing.
5. Describe the differences between physical, virtual, and logical memory.

 Your response must be a complete APA lab report (title page, conclusion and references page) and your own work. The conclusion should be your thoughts. 

Using one of the referenced website articles discuss single-queue versus multi-queue scheduling

You must post your initial response (with references) before being able to review other student’s responses.
