Pernah kah kalian merasa apa yang kalian jalani dalam hidup sangat membosankan ?
apakah pernah kalian berfikir untuk berhenti belajar?
saat TK kita senang karna hanya bermain dengan teman teman kecil kita, saat akan masuk SekolahDasar kita merasa senang karna merasa sudah besar dan bisa punya lebih banyak teman, saat sudah menginjak kelas 5 sd, kita sudah mulai takut dengan ujian, tanpa terasa kelas 6, kita berhasil melewati EBTANAS/UAN kita senang saat akan mulai kembali di pelajaran baru di SMP, lalu kembali stres saat menginjak kelas 3 dengan tugas yang begithu menumpuk,akhirnya kita melewati lagi masa2 dengan susah payah dan usaha yang keras, Menginjak SMA semakin dewasa jua lah harusnya cara berfikir kita dengan makin banyak pula segala macam tugas, LES, bimbel, band, persahabatan, dan mulai di singgahi oleh 'cinta', yang normalnya akan melanda hati setiap manusia normal ..patah hati..sakit ..bangkit lagi..itulah kehidupan.Dan dari semua itu kita hanya di tuntut untuk belajar! ya hidup adalah belajar..bukan hanya di sekolah bukan hanya orang yang bisa bersekolah tapi belaja dari segala hal yang selalu kita hadapi setiap hari nya ..buat lah hidup ini bermanfaat, hidup tidak akan pernah membosan kan saat kita bisa saling berbagi, berbagi pengalaman, cerita, ilmu, pengetahuan, harta apapun itu!
Karena kebagiaan hidup adalah saat kita melihat orang-orang di sekeliling kita tersenyum dan bahagia.Belajarlah dengan berbagai pengalaman hidup yang setiap hari menguji kita , yakin lah setiap saat kita selesai dan mampu menghadapi ujian itu kita akan memasuki level yang lebih tinggi dalam kehidupan untuk menjadi yang lebih baik. Untuk apa kita menjadi lebih baik?
-Untuk sesama-
Semoga kita bisa menjadi seseorang yang dapat memberikan manfaat bagi sesama...
Information system : The related component that can we use for access a data or informasi quickly and appropriately. . .
BalasHapusHow important information system for business : because in the business the data or information must be access quickly and appropriate so we can use information system for this purpose
i think that's all. . .

BalasHapusInformation Technology defined as the"the study, design, development, implementation, support or management of computer-based information systems, particularly software applications and computer hardware."
BalasHapusAbout the important of information technology i think, on this lately computer and internet is already received by huge line business countries(exp: USA, England, China, Germany, Japan, etc).They're using the internet for advertising, data transferring, goods transaction, etc. As Aryanto explanation "because in the business the data or information must be access quickly" so the information technology must be always up to date for keeping the transferring data smoothly on every business.
That's all for number one explanation,

Knowledge Worker System are professionals who create new information as part of their job. example : an programmer would use a system to help him design a software.
BalasHapusDecision Support Systems (DSS) are information systems that help managers make decisions that are not routine. example : a business manager choosing the amount of a product to manufacture.
Expert Information Systems (EIS) are top executives that involved in high level strategic planning. example : a CEO might need overall sales information for his company.
Management Information Systems (MIS ) are can't involved in details of daily operations. they require information systems that can generate reports and warn them when problems are occuring in their particular area of responsibility. example : division manager that can intervene early to correct problems.
Office Automation Systems (OAS) are support office workers. these employees way create, use, and manipulate data in their work, but they don't typically create new information. examples : word processing, spreadsheet software programs.

BalasHapusHere I'm giving SDLC examples in Theory + Pratice in business environment.
BalasHapusA. System Development Life Cycle (SDLC) Model
This is also known as Classic Life Cycle Model (or) Linear Sequential Model (or) Waterfall Method. This model has the following activities.
1. System/Information Engineering and Modeling
As software is always of a large system (or business), work begins by establishing the requirements for all system elements and then allocating some subset of these requirements to software. This system view is essential when the software must interface with other elements such as hardware, people and other resources. System is the basic and very critical requirement for the existence of software in any entity. So if the system is not in place, the system should be engineered and put in place. In some cases, to extract the maximum output, the system should be re-engineered and spruced up. Once the ideal system is engineered or tuned, the development team studies the software requirement for the system.
2. Software Requirement Analysis
This process is also known as feasibility study. In this phase, the development team visits the customer and studies their system. They investigate the need for possible software automation in the given system. By the end of the feasibility study, the team furnishes a document that holds the different specific recommendations for the candidate system. It also includes the personnel assignments, costs, project schedule, target dates etc.... The requirement gathering process is intensified and focussed specially on software. To understand the nature of the program(s) to be built, the system engineer or "Analyst" must understand the information domain for the software, as well as required function, behavior, performance and interfacing. The essential purpose of this phase is to find the need and to define the problem that needs to be solved .
3. System Analysis and Design
In this phase, the software development process, the software's overall structure and its nuances are defined. In terms of the client/server technology, the number of tiers needed for the package architecture, the database design, the data structure design etc... are all defined in this phase. A software development model is thus created. Analysis and Design are very crucial in the whole development cycle. Any glitch in the design phase could be very expensive to solve in the later stage of the software development. Much care is taken during this phase. The logical system of the product is developed in this phase.
4. Code Generation
The design must be translated into a machine-readable form. The code generation step performs this task. If the design is performed in a detailed manner, code generation can be accomplished without much complication. Programming tools like compilers, interpreters, debuggers etc... are used to generate the code. Different high level programming languages like C, C++, Pascal, Java are used for coding. With respect to the type of application, the right programming language is chosen.
5. Testing
Once the code is generated, the software program testing begins. Different testing methodologies are available to unravel the bugs that were committed during the previous phases. Different testing tools and methodologies are already available. Some companies build their own testing tools that are tailor made for their own development operations.
6. Maintenance
The software will definitely undergo change once it is delivered to the customer. There can be many reasons for this change to occur. Change could happen because of some unexpected input values into the system. In addition, the changes in the system could directly affect the software operations. The software should be developed to accommodate changes that could happen during the post implementation period.

BalasHapusDescribe the Phases of the system Development life cycle!
BalasHapusPlanning Phase
The concept is further developed to describe how the business will operate once the approved system is implemented, and to assess how the system will impact employee and customer privacy. To ensure the products and /or services provide the required capability on-time and within budget, project resources, activities, schedules, tools, and reviews are defined. Additionally, security certification and accreditation activities begin with the identification of system security requirements and the completion of a high level vulnerability assessment.
Requirements Analysis Phase
Functional user requirements are formally defined and delineate the requirements in terms of data, system performance, security, and maintainability requirements for the system. All requirements are defined to a level of detail sufficient for systems design to proceed. All requirements need to be measurable and testable and relate to the business need or opportunity identified in the Initiation Phase.
Design Phase
The physical characteristics of the system are designed during this phase. The operating environment is established, major subsystems and their inputs and outputs are defined, and processes are allocated to resources. Everything requiring user input or approval must be documented and reviewed by the user. The physical characteristics of the system are specified and a detailed design is prepared. Subsystems identified during design are used to create a detailed structure of the system. Each subsystem is partitioned into one or more design units or modules. Detailed logic specifications are prepared for each software module.
Development Phase
The detailed specifications produced during the design phase are translated into hardware, communications, and executable software. Software shall be unit tested, integrated, and retested in a systematic manner. Hardware is assembled and tested.
Integration and Test Phase
The various components of the system are integrated and systematically tested. The user tests the system to ensure that the functional requirements, as defined in the functional requirements document, are satisfied by the developed or modified system. Prior to installing and operating the system in a production environment, the system must undergo certification and accreditation activities.
Implementation Phase
The system or system modifications are installed and made operational in a production environment. The phase is initiated after the system has been tested and accepted by the user. This phase continues until the system is operating in production in accordance with the defined user requirements.
Operations and Maintenance Phase
The system operation is ongoing. The system is monitored for continued performance in accordance with user requirements, and needed system modifications are incorporated. The operational system is periodically assessed through In-Process Reviews to determine how the system can be made more efficient and effective. Operations continue as long as the system can be effectively adapted to respond to an organization’s needs. When modifications or changes are identified as necessary, the system may reenter the planning phase.
Disposition Phase
The disposition activities ensure the orderly termination of the system and preserve the vital information about the system so that some or all of the information may be reactivated in the future if necessary. Particular emphasis is given to proper preservation of the data processed by the system, so that the data is effectively migrated to another system or archived in accordance with applicable records management regulations and policies, for potential future access.

1. What is Information Technology? And why is it important to a business?
BalasHapus- Information Technology is a tool that used to sharing and access information between people that have their own goal.
- The most important in business is communication, without communication, business world will be lack of sharing information. Technology can make it to more and more easier to communicate with the others.
Example :
PAST (before we have internet) : people share their information of a product such as catalog, brochure, they need come to the office to get it or send it by post. We need to wait until receive the catalog. It spend a lot of time just for a detail of a product before dealing.
But NOW (already have internet) : everybody can use internet like mail easily and more comfortable, because it can send detail of product anytime and anywhere, just attach a document / file that describe the product and send it. It save a lot of time. Because we don’t need to wait receiving a document. We receive it directly after they send it.
That why technology information is important to a business.

Information technology is all tool or thing that is use for sharing,spreading,receiving,accesing,duplicating,deleting, information between user.
BalasHapusIT is needless to say IMPORTANT, IT is need to improve all the process in business, thus improve efficiency of the whole business and gain greater gain
3. Describe five type of Information System and give me an example of each!
BalasHapus- OAS (Office Automation System)
A based system that includes and provides applications such as a word processing, spreadsheet, database, or mail.
Ex : in a company they need these application to get information, to searching, to planning a strategy. For instant, a company need a database to keep the data safely and etc.
- MIS (Management Information System)
A system with covering of technology applications to solve a business problems
Ex : in a cycle of business they need reporting periodically from accounts, inventories, purchase to statistic the result of a company and Information System will help and control the company managing enterprise with applications that IS provided to develop.
- KWS (Knowledge Worker System)
An application that designed to help knowledge worker or professionals to use the information or input process.
Ex : an autocad application that design for architecture engineers to develop the design or plan.
- ES (Expert System)
A system that provide software to solve a specific problem.
Ex : when there’s got problem in a company the system attempts to solve a specific problem with their different knowledge from expert system technlogy.
- EIS (Executive Information System)
Is similiar with MIS but this is used for senior executives to support decission making.
Ex : usually a top manager need to analysis both the internal and external information to make a decission and achieve the goal of an organization.

I want to add a lil more to my answer just now.
BalasHapusIT is also make managing and processing the whole data of a company a lot easier,its also enable a company to receive and spread information quickly.
without IT, a business effeciency will drop significantly.
P.S
i also post a answer in the comment section of another post, i see it already being used here. so i post a new answer here.
sorry for all the inconvinience.
P.P.S
Ms. Ayu , can you please dont give us a task for EVERY chapter you teach?!!
i dont mind, if it was once in a while(atleast 2 chapter)but not every chapter please!!
Pretty please with a cheery on top!!!
XD
(The thing above is just a rambling from a selfish,lazy student of yours.If it was in anykind of way bothering you, feel free to ignore it..I once again apologize for the inconvinience)
No.3
BalasHapus1. Decision support system (DSS):
Helps strategic management staff (often senior managers) make decisions by providing information, models, or analysis tools. For support of semistructured and unstructured decisions (structured decisions can be automated). Used for analytical work, rather than general office support.
They are flexible, adaptable and quick. The user controls inputs and outputs. They support the decision process and often are sophisticated modelling tools so managers can make simulations and predictions. Their inputs are aggregate data, and they produce projections.
An example job for a DSS would be a 5 year operating plan.
2. Management information system (MIS) :
Condenses and converts TPS data into information for monitoring performance and managing an organisation. Transactions recorded in a TPS are analyzed and reported by an MIS.
They have large quantities of input data and they produce summary reports as output. Used by middle managers.
An example is an annual budgeting system. Manager can be early to correct problems / could include executive information packets, credit
approval and take-out commitments, and funds management systems.
3. Executive information system (EIS):
Also known as an Executive Support System (ESS), it provides executives information in a readily accessible, interactive format. They are a form of MIS intended for top-level executive use. An EIS/ESS usually allows summary over the entire organisation and also allows drilling down to specific levels of detail. They also use data produced by the ground-level TPS so the executives can gain an overview of the entire organisation.
Used by top level (strategic) management. They are designed to the individual. They let the CEO of an organisation tie in to all levels of the organisation. They are very expensive to run and require extensive staff support to operate.
Example : director of main office / president of Lockheed-Georgia, monitors employee contributions to company-sponsored programs (United Way, blood drives) as a surrogate measure of employee morale CEO of Duracell.
4. Office automation system (OAS) :
OAS provides individuals effective ways to process personal and organisational data, perform calculations, and create documents. e.g. word processing, spreadsheets, file managers, personal calendars, presentation packages. They are used for increasing personal productivity and reducing "paper warfare". OAS software tools are often integrated (e.g. Word processor can import a graph from a spreadsheet) and designed for easy operation.
OAS Subspecies:
Communication systems: helps people work together by sharing information in many different forms
Teleconferencing (including audioconferencing, computer conferencing, videoconferencing), electronic mail, voice mail, fax
Groupware system: helps teams work together by providing access to team data, structuring communication, and making it easier to schedule meetings. For sharing information, controlling work flows, communication/integration of work
Example : Invoice scanning and approval process
Post scanning , OCR and automated distribution to email
Document review and publication work flow
5. KNOWLEDGE WORK SYSTEMS (KWS): are used by technical staff. KWS use modelling functions to convert design specifications into graphical designs. They may include computer-aided design/manufacture (CAD/CAM).
Example : improves workgroup coordination by allowing knowledge workers to retrieve and update milestones, task completion, and priority status information.

What is Information Technology?
BalasHapusInformation Technology or IT, also cited as Information Service (IS) or Management Information Service (MIS), can be defined as the development, design, study, implementation and management of computer related information. It can also be defined as the use of computer (hardware and software) to manage information.
why is it important to a business?
Computer technology has great applications in almost all kinds of businesses. Almost all kinds of businesses are relying on computers for automating their traditional processes. Businesses use wide variety of databases, management information systems, information sharing platforms, data sharing networks, internet, intranets, machines, equipments etc which highly rely on computers. The use of computer technologies is not only in the field of finance or marketing , it is also being used by the medical industry, human resource departments, inventory control management systems etc. Computer technologies help to perform the routine business tasks much quicker as compared to the traditional way of doing things. Some companies use data warehouses, data mining techniques, decision support systems to aid in their decision making processes.

1. The most important component of a computer system is the CPU, or central processing unit, which consists of the Motherboard, hard drive, and connector cables.
Operating Systems
2. The operating system runs the software on your computer, provides security and tracks other programs to ensure compatibility. Examples include Microsoft Windows, Linux or Apple's Macintosh.
The Monitor
3. The next main component is the monitor, or display screen. This screen also helps deliver warnings or messages when there is a problem with the CPU or Operating System.
Keyboard
4. The keyboard allows you to input commands and/or communicate with others on the Internet.
Mouse
5. Using a mouse, you can interact with the Operating System or any variety of programs or software.
Hard Drive
6. Hard drives, where most information is stored, include the internal drives ("C" and "D") as well as the CD/DVD drives. They also allow access to the Operating System and other programs. Other hard drives include pen drives and zip drives.

BalasHapusAnswer the question number 4:
What is the Internet?
The Internet is a global system of interconnected computer networks that use the standardized Internet Protocol Suite (TCP/IP) to serve billions of users worldwide. It is a network of networks that consists of millions of private and public, academic, business, and government networks of local to global scope that are linked by copper wires, fiber-optic cables, wireless connections, and other technologies.

BalasHapusAnswer Question number 3:
Q:What is different between a LAN,a WAN,and a MAN?
A:
LAN(Local Area Network)A group of computers thet share a common connection and are usually in a small area or even in a same building.
For example an office or home network. they are usually connected by Ethernet cables and have high speed connections , If it was a wireless setup it would be called a WLAN, Which would have a lower connection speeds.
MAN(Mertopolitan Area Network) This is a large network that connects computer users in a particular geographic area or region .
For Example a large University may have a network so large that it may be clasified as a MAN. The MAN network usually exist to provide connectivity to local ISPs,cable TV,or a large corporations. It is farlarge than a LAN smaller that a WAN. Also large cities like London and Sydney,Australia have Metropolitan Area Network.
WAN(Wide Area Network)This is a largest network and can interconnect network throughout the worldand is not restricted to a geographical location. The internet is an example of a worldwide puvlic WAN. Mosr WANs exist to connect LANs that are not in use the same geographical location. This technology is higy speed and very expensive to setup.
I hope these definotions helped as i have tried to explain LAN,MAN, and WAN in non technical terms.
