Science Computer Is Amazing

First of all praise to Allah for given me lives to writing my new post.For my new post the topic that is given to me is "What is your favourite subject your mostly like and the topic thah you think is easy?My answer will be it is Science Computer because for me it is not to hard and also not to simple.The topic that is easy for me to understand is Topic 1:Development of Information.The first topic is divided into two that is Development of IT and Application of IT.The first thing that we need to know is to define IT.What do you know about IT?Information Technology can be defined briefly as the use of computer hardware and software to store,retrieve and manipulate information.Other definition of IT is refers to anything related to computing technology such as networking hardware,software,the Internet or the people that work with these technologies.IT divided into 5.

It is Standalone,mainframe,client-server,distributed computing and cloud computing.Definition for standalone is a desktop or laptop computer that is use on its own without requiring a connection to a local area network(LAN) or wide area Network(WAN).Example of standalone is Window,Mac OS X,UNIX and Linux.Advantage and disadvantage for standalone is prevent from hacking activities,protect our privacy and cannot share data with other computer and hardware(rinters with other computer).

Mainframe is a large,expensive,powerful computer that can handle hundred or thousand of connected users simultaneously.Advantage and disadvantage for mainframe is we can save many data because it have huge memory and high security also require backward operating system compatibility with mainframe.

The other It is client-server which can defines as the relationship between two computer programs in which one program,the client make a service request from another program.Advantage and disadvantage of client-server is all data is stored centrally it is easy to backup and it server network can be expensive to maintain and implement.

Distributed computing is a single computer program that is runs in more than one computer at the same time.The advantage and disadvantage is while setup the program run like it would in a single computer and if the network gets saturated or down then the promblems is with the taransmission will surface.

Lastly is cloud computing and it is defined as a technology that uses the Internet and control remote server to maintain data and application.The advantage and disadvantage  is we only pay for what we are use and if you do not have internet connection you cannot use cloud computing.
