BULLETIN : COMPUTER ATTACK

HELLO EVERYONE :)
Today im going present you about my new assignment under topic COMPUTER SECURITY RISKS.

 That all for today. see you nice time :))))

NETWORK ARCHITECTURE

HELLO EVERYONE :)))))
TODAY IM GOING TO PRESENT MY GROUP TASK UNDER TOPIC NETWORK ARCHITECTURE. YEAYYY !!

 Let me explain about this model.

• First we use  client server network. 

So client server network is one or more computers act as a server and the other computer on the network request services from the server.
The advantages of this type of network architecture are it work in any size of networks and does not tend to slow down with heavy use and security is more advance that the other one network.

• For the topology, we use star topology.

Star topology is devided into two which is physical and logical star topology. physical star topology uses a central device (hub/switch) where all the nodes box connected to it using cable.
For logical star topology, all data that transfer from one more to another passes through the hub or switch untill it reaches the destination node.
The advantage of this advantages is adding or removing a node doest not effect the rest of the star network. failure of one node usually does not effcect the rest of the star network.
The disadvantages is of the central device fails, the entire star network fails and it is more expensive to setup because of the cost of the switch /hub.

• For the classification of network, we use local area network (LAN)

Local area network is a network that connects computers and devices in a limited geographical area such as home, school or office building. as you can see in our model, we use office building. the network only covered just in the building only. even the computer is on the different floor it's still receive the same network. the advantages is allow users to share all the resources and it reduce cost because the hardware can be share. the disadvantages is area coverage is limited and as the data is shared  there is the greater need for security which is it expose to viruses. so thats all for the explaination of the model. we use the model is because we want to show that only the office building will receive the network. the others surrounding wont receive the network.

That all for todayy. see you next time and have a nice day <3
