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

what is storage capacity ?

Assalamualaikum and hi there *smile*

today i would like to share my last thinking map. for the last one, i used circle map to explain the meaning of storage capacity. so i hope my thinking map will clear up all the question about storage capacity.

i hope you guys enjoy with my post, thank you for reading my blog and have a nice day <3

Information Processing Cycle (IPO) model

Assalamulaikum and hi everyone :)

today, i would to share my third thinking map. this time i used flow map to describe about Information Processing Cycle (IPO) model. so here you go :D

Flow Map

so thats all for my post this time. i hope you guys enjoy ! <3

what is computer system ?

Assalamualaikum and hi everyone.
today, i would like to share my second thinking map. this time, the thinking map will explain to you about what is computer system. i used tree map to explain the computer system. so enjoy :)

what is computer ?

Assalamulaikum and hi everyone.
today i would to share my thinking map :))))))) yeayy !
i choose, bubble map for my first thinking map. i used the bubble map design to ease anyone which do not understand what is computer.  so here go ~~

Information Technology (IT)

Assalamualaikum and hi there :)
Today i would like to share my own     handmade    brochure that i did for my assignment a few week ago. So here you go !

page 1 ☺

page 2 ☺

 

click each picture for a very very clear picture hehe :))

I hope my brochure will help you to understand what is actually mean by Information Technology (IT).
Thanks to Madam Moi, my Computer Science lecture in KMS.

what is computer science

WHAT IS COMPUTER SCIENCE ??

Computer Science is the study of computers and computational systems. Unlike electrical and computer engineers, computer scientists deal mostly with software and software systems; this includes their theory, design, development, and application.
Principal areas of study within Computer Science include artificial intelligence, computer systems and networks, security, database systems, human computer interaction, vision and graphics, numerical analysis, programming languages, software engineering, bioinformatics and theory of computing.
Although knowing how to program is essential to the study of computer science, it is only one element of the field. Computer scientists design and analyze algorithms to solve programs and study the performance of computer hardware and software.
