  Designing a SOHO network with DHCP Network requirements for the office Sales department – 4 computers Finance department – 3 computers Networking devices requirement: ·          1 router ·          2 switches (one for each department) ·          1 DHCP server Documentation I started by setting up the network topology and used the automatic connecting cable to connect all the devices together. Then I configured the server with IPv4 address and a subnet mask. to do this you have to press on the server and then go to desktop. Then I filled in all the parameters as seen below. Then I had to configure the DHCP server. To do this I clicked on the server > services > DHCP. Then I turned on the serves and configured the server as seen in this screenshot. For the next step I configured the router with the IPv4 address and subnet mask. To a...

Types of network adapters in virtual box

  Types of network adapters in VirtualBox In VirtualBox there’s multiple types of network adapters that can be used to configure virtual machines for different networking needs. Down below will give you a brief overview of each type. NAT (network address translation) The VM is placed behind a VirtualBox-managed router. This allows the VM to access the external network via the networks host’s IP, but the VM itself remains invisible to the outside. Its most suitable for simple internet access with minimal configuration NAT network This is like NAT, but it allows multiple VM’s to communicate with each other in the same NAT network all while sharing the host’s internet connection. Its commonly used when you want to simulate a small, isolated network of VM’s that can also access the internet. Bridged adapter This VM is connected directly to the physical network as if it is a separate device, it also receives its own IP address from the same network as the host. This is ide...

CAT cables

  CAT cables Theres many types of CAT cables, and they are commonly used for Ethernet and other networking purposes.   Types Theres 5 main types of CAT cables: ·           CAT5e (Category 5e): This is an enhanced version of the CAT5 cable, offering improved performance and support for higher data transfer rates. It is suitable for most home and small business networking needs. ·           CAT6 (Category 6): CAT6 cables provide even higher data transfer rates and reduced crosstalk compared to CAT5e. They are commonly used in professional installations and are suitable for gigabit Ethernet and some 10-gigabit applications. ·           CAT6a (Category 6a): The "a" stands for "augmented." CAT6a cables are an enhanced version of CAT6, offering even higher data transfer rates and better performance, especially in terms of crosstalk and signal quality...
