There are two type of windows users.

Local users: only could be open in one machine.
Every time you log in a computer you have to remember to log off.

Domain users: you can open the same user in a group of computers (domain).

Domain controller: you need to be connected to the network and if the network falls you can’t access.

NIC IP CONFIGURATION

-          Every time you want to configure your computer you need four numbers. Each PC has its own IP ADDRESS.

-          You need another number that is called Network Mask.

-          In the Network Mask all the numbers start with: 255. For example: 255.255.255.0

-          The Network Mask allows you to know how many computers are connected

-          THE GATEWAY: here you should have the internal IP ADDRESS of the router. If the internet wires are not connected, you won’t be able to check your Gateway.

-DNS (Dynamic Name Server): We wouldn’t have internet without the DNS. If you have problems with your DNS, you can take your card and write: 8.8.8.8 on it to fix it. At school we have private DNS because we have our own DNS servers.

IP ADDRESSES

Today, in the ICT lesson we learnt what an IP ADDRESS is and its types, we also learnt how to change your NIC IP Configuration and the most important peripherals.

-          An IP ADDRESS is a group of four numbers separated by dots. The first number shouldn’t be higher than 256. Types of IP: Public and Private, Static and dynamic:

-          PUBLIC: they are the ones that can be found on the internet.

-          PRIVATE: it is something that you have to connect to a router without showing your IP Address on the internet. It usually starts with a 10 or 192, for example: 192.168.X.X or 10.X.X.X

-          STATIC:   it is manually configured.

-          DYNAMIC:  it is an IP ADDRESS that is configured externally and that changes every time you turn your router on.

-          A router has two IP ADDRESSES, one is Public and the other one is an internal IP ADDRESS, the Private one. 

NIC IP CONFIGURATION

NIC IP CONFIGURATION

To configure it you will only need four elements:

• IP Address: 4 numbers separated by dots. The limit is 255.x.x.x

• Network Mask: Its always 255.255.255.0

• Gateway: It's the IP of the router; for example: 10.0.72.254

• DNS (Dynamic Name Server): It's the public IP Address of a machine; for example: 8.8.8.8
