You are a network administrator, been tasked to create a network connection of 3 different departments. Each department has got 3 pc's. In your network include DNS server, Web server, email server
Discuss how an operating system protects computer
hardware, processor, main memory, and input-output
devices of a computer system; and provide
appropriate practical examples to illustrate your
answer.
You have subnetted your class B network 190.220.1.0 with a subnet mask of 255.255.255.224. Please list the following :
- Number of subnet bits.
- Number of networks.
- Number of hosts per network.
- The full range of first two networks.
- The usable IP address range from those
first two networks.
- The broadcast address for first two
networks.
You have sub-netted your class C network 200.138.1.0 with a subnet mask of 255.255.255.252. Please list the following: number of networks, number of hosts per network, the full range of the first three networks, and the usable address range from those first three networks. Additionally, identify the broadcast addresses for each network.
Let we have 8 nodes in the network. Compare the network performance with different connectivity device's like repeater, hubs, switches, router, bridges and gateway.
Show the contents (in hexadecimal) of register PC, AR, DR, IR and SC of the basic computer when an LDA instruction is fetched from the memory and executed. The initial content of PC is 7FF. The content of memory at address 7FF is AA9F. The content of memory at address A9F is 0C35.The content of memory at address C35 is FFFF. Show the Content of register in tabular format also.
Let we have 8 nodes in the network. Compare the network performance with different connectivity device's like repeater, hubs, switches, router, bridges and gateway.
find the class of each address.
a) 00000001 00001011 00001011 11101111
b) 11000001 10000011 00011011 11111111
c) 14.23.120.8
d) 252.5.15.111
What are the physical and virtual security risks?
Write the following IP addresses in CIDR notation: 135.1.1.25 Mask 255.255. 248.0
