Q: A company has a 190.240.0.0/16 block. They now want to re-organise it into large blocks. They wish to have subnets that can handle at least 1000 hosts each. You can substitute into the formulae 2 S >= subnets required and 2 H -2 >= hosts required - to determine the number of bits required. Please calculate: S = bits used for subnetting H= bits used for the number of hosts in each subnet Also, please calculate the following for the second subnet: subnet mask subnet address first usable address in that subnet last usable address in that subnet broadcast address of that subnet A: Network currently first two octets 16 bits: 11111111.11111111. Host second two octets 16 bits: 00000000.00000000 Subnet = 255.255.0.0 In order to provide a minimum of 1000 hosts per subnet we need to retain 10 host bits of the current 16 - 2 to the power of 10 = 1024 minus 2, 1 for network and 1 for broadcast leaves 1022. We now have 6 bits of the thrid octet that ...

Understanding business users profiles The proposed network must support the users in achieving their goals and supporting the organisation in providing a competitive service to its customers. In order to properly understand the needs the context of the users work needs to be determined. There are two requirements we must understand: - The functional requirements which tell us what the system must do - The non-functional requirements which places constraints on the system  Steps taken to determine requirements: 1. Identifying the business users 2. Establishing users needs  3. Categorizing requirements       The above analysis makes the assumption that laptops will be provided to all employees. This offers flexibility in terms of: - Portability  - Hot desking - Remote working - Flexible work options - Collaborative working  - Presentations and meetings - Run off batteries - Reduce desktop clutter and wires - Can be transforme...

In order to work out the Subnet address  you will need for your local networks you will need two things:  1) your IP address eg:192.168.1.0 2) The Subnet mask 255.255.255.0 If we had a look at the Subnet mask we can see that the network has 3 place holders, which works out to be 8 bits long or  1 octet.  first step we convert both address into their binary form.  The blue  numbers represent the octets dedicated to the network while the orange numbers are put aside for the host machines.  In order to see the subnet address we use an action called the bitwise AND. This works by dropping all the 1's that have both a 1 in the IP address and Subnet mask. This calculation will give us network address : 11000000.10101000.00000001.00000000 or                                                    ...

Dedicated Servers   Prices in USD Budget friendly option:    Value to Performance Option:    Eco Option:   Cloud Servers Price based on spec selected and subject to change:   Although these are initial costs it would suggest that a dedicated server might be a more cost effective option.  For added security a hybrid system might be a better option utilizing a cloud storage solution for back-ups.
