TOPIC 5

Simply put, Internet is all about network. Internet is the largest network in the world that connects people or organization all over the world. 
     
In this 21st century, the internet has helped humans a lot by making work easier and faster. Internet can be used for the following checking information and finding informationr,sending or recieving files, share resources, shop for product, send emails, interact and socialize with people. In 1960, the US Defense Advanced Research Project(DARPA) began to study ways to interconnect network in various kinds.“ARPANET”- Advanced Research Project Agency Network (1969). Below is a diagram which illustrates the services provided by internet.

  
Actually, there are several services provided by the internet.This internet applications includes Email,World Wide Web(WWW), Protocol,Chat rooms,Instant messages etc.Furthermore, web browsers depend on URL to identify exact web pages thus URL-Uniform Resource Locators is a four part addressing scheme that tells the web browser the domain name, the transfer protocol, the name of the file and lastly the path name of the folder or directory on the computer on which the file resides.In other to access the web ,one needss an internet connection, an interent network service provider and any web browser be it Mozilla,Torch,Google ,Internet Explorer etc.Also, the transfer protocl is the set of rules or software that the computers use to move files from one computer to another on the internet whiles chat room is a channel/location on the internet that allow people to chat with eachother. Eg.Facebook, gmail, whatsapp, waplog, etc.Moreover, VOIP-voice over internet protocol allow users to make phone call and video calls over the internet. eg. are viber calls, line,skype,facebook video calls, Yahoo voice etc.

 

This was the end of the lesson for Topic 5

TOPIC 3

In this week session, I learnt about Information System. Information System is a set of elements of component, eg. Input,Processing , Output. Also, CB Information is a combination of  hardware , software,telecommunication networks that people build and use to collect, create, distribute,data or information. Below is a diagram of  basic system model.

CBIS is used in an organization to support business operation, support competitive advantage and also to make a business  decision.Furthermore, there are three types of Information needed in an organization namely: Strategic, Tactical and Operational. Below is a diagram to illustrate how it is used.

The components of CBIS include procedure, Telecommunications, database, Software, hardware, people etc. hence the components of Information hardware are Input device, processing device,output device, storage device. The storage holds data, instructions, and Information for future reference.  The categories of software are system software, Application software and programming language. A programming language is a set of words,abbreviation,and symbols that enables a programmer to communicate instructions to a  computer. This   includes COBOL,etc. Moreover, an IS database is an organized collection of interrelated data(records).The  TPS is the backbone of an organization's information system.TPS components involves people,the user, participants, hardware and software.

 

The types of information system include TPS,MIS,DISS,ESS/EIS. Actually,ISD or System Development is a process of defining, designing,testing and implementing a new software application or program. ISD methodologies is a collection of procedures,techniques,tools and documentation aids which will help the system developers in their efforts to implement a new information system.There are also three types of ISD methodologies namely SDLC,Prototyping and Stradis. The SDLC stages involves system investigation,system analyst,system design,system implementation and system maintenance and review. Finally, the stages in STRADIS are design study,designing alternatives, physical design and implement system.

This is among some of the lessons learnt in Topic 3.

TOPIC 2

At the previous week, we were ask to form a group of six (6) and then given a task.At the beginning beginning of week 2, we were asked to present  about our topics. In Topic 2, was ICT and IT. During this topic lessons I learn about the differences between ICT and IT. ICT refers to Information Communication Technology whiles IT(Information Technology) is a term that refers to all forms of technology used to create, store,exchange,and use info .   

 We have two types of Concepts Information Technology namely:

• Information Technology Architecture:

1. A map or plan of the information assets in an organisation.
2. Integrates entire organisation’s business needs for information, infrastructure and applications. 

       

Information Technology Infrastructure refers to the physical facilities, IT Components, IT services and IT personnel that support an organization.

Information System (IS) is the study of complementary networks of hardware and software that people and organizations use to collect, filter,process,create and distribute data.

The week topic followed the uses of ICT in our daily life  ICT can be used in different industrial sectors like in the hospitals, Homes, Schools, Banks,Shops,Government agencies, etc.

   

       
We also did a classwork on bibliography citation. Below is an example of mine.

This   is among some of  the lessons learnt in Topic 2.

TOPIC 1

During the first week of Information Technology ,our lecturer brush through what we learnt at Computer and
Internet in the likes of definition of computer, the categories of computer namely:
Embedded computers,Mobile devices/ computers,Personal computers,Mid range servers,Mainframes, Supercomputers, and Hybrid computers.Also, the generation of computers, the basic operations a computer can perform etc. Actually, we have five generation of computers that is from the First generation(Vacuum Tube) to the fifth generation(Artificial Intelligence-Now and the future). Further from the week lessons, I learnt about Data and Information and below is a summary:

Data is a collection of facts, figures and statistics related to an object and  can be processed to

 create useful information whiles Information is the manipulated and processed form of data. 

Much more, computers process data into information.     

             Much more Information plays three role which are:

1. Information is used to influence and persuade.
2. Information can be a capital resource, especially for companies that produce information-based products and services.
3. Information is used in decision-making.

Furthermore, information has two basic elements namely Richness and Reach. The richness has further three(3) components known as Bandwidth, Customization and Interactivity. A computer uses the "IPO" method to convert Data into Information, hence "IPO" stands for Input ,Processing and Output. An input device is any hardware component that allows users to enter data and instructions into a computer whiles An Output device  is any type of hardware component that conveys information to one or more people. Below is an examples of input device:

         

Below is also an example of output device:

     

The CPU is main brain of the computer. It is where all the calculation in a computer takes place. It consists of three basic part namely Arithmetic and Logical Unit, Control Unit,and  Registers. Below is a diagram view of the parts.

A      Actually, we did learn what is Information Management,Problems associated with IM, and the necessary solutions. We were also given an assignment to find the problems of IM and the solutions. This task broaden my mind since it was a group assignment where I had numerous discussion with my group mates. IM is the the discipline that covers the definitions, uses, value and distribution of all data and information (organization OR whether processed by computer). Some problems of IM includes Data Lost,Lack of Storage, Unreliable Information,Hacking,Virus,Unreliable Information,Incomplete Information etc.

This  is among some of the  knowledge I acquired in  Topic 1.Thank You.

Topic 4

 
From TOPIC 4 lessons, I learnt about Database System. After the week lesson, we did a text on the topic.Database is an organized collection of data or a collection of information arranged and presented in alphabetical order.Database performs the functions as follows to store data,organize data and control data.They are also two components of database namely Data Item and Schema.the types of database include Individual database,Company shared database and Distributed Database.Furthermore, the types of database model are Hierarchical and Network,Rational and   Object-relational database. Actually, Data base management System is a software package for manipulating databases.ed includes Microsoft access,clipper, Filemaker, dBASE, Oracle etc. Also DBMS users are End users,Application users and Data Administrator users. Moreover, modern  database architecture consists of actual database contents,hardware to process and store data, software to manipulate the contents and people to administer the access control and modification of data. The features of a DBMS includes allowing users to create new databases, giving users the ability to query and modify the data using appropriate language and provides information to the decision makers that they need to make important decisions. The components of DBMS includes Field,Record,Table, Key field etc.the Hierarchical model organizes data in a tree structured (upside down tree) whiles the network model is represented by records using links among them.Among the language database uses are DDL- data definition language ,DML-data manipulation language AND SQL- structured query language.

    

This and among other things is what i learnt in topic 4.

TOPIC 6

         

The last topic of the subject was web application. Previously, I thought the internet is the same as the web, but the the topic lessons, my point of view changed totally. During the weeks lessons,I learnt that Internet is not the same as a WEB hence Internet is a network whiles Web is created by someone. Furthermore, architecture web application use a combination of Cript- Sintex,  Client-User and  Server- Mainframe. Also, I did learn about the characteristics, differences and examples of Webs.
  
 Below is visual view of the characteristics and difference between Web 1.0 and Web 2.0

        

The web 2.0 offers many interactive software choices,many of which have become household names. Here are some examples: free web-based email, online banking, project management tools, word processing, spreadsheet, online radio,video hosting etc. Actually, to summarize it all, web 1.0 information is displayed hence one can not edit . eg. is an educational website, whiles web 2.0 is the poppular term for advanced internet.With web 2.0 , one can edit,the content of the page. eg. Wikipedia, thus web 3.0 is about semantic web. eg. DSS,ESP, Intelligent application. This means that web 2.0 is dynamic whiles web 1.0 is static. 

Below is a diagram to the difference between the three webs.

This are some of the lessons I learnt  on the topic.
