Internet comes from the word Interconnection Networking is of significant relationships with various types of computers that form a network system that covers the entire world (global computer network) by means of telecommunications such as telephone lines, radio links, satellite and others.In regulating the integration of computer networks and communication protocols are used is TCP / IP. TCP (Transmission Control Protocol) ensures that all links work properly, while the IP (Internet Protocol) which transmits data from one computer to another. TPC / IP is generally the best route for data transmission, selecting an alternative route if a route can not be in use, manage and deliver packets of data transmission.

To be eligible to use the Internet facilities, you usually have to subscribe to an ISP (Internet Service Provider) that exist in your city. ISPs are usually called Internet service providers or you can use the facilities from Telkom Instant Telkomnet.By utilizing the Internet, computer usage around the world possible to each other communicating and sharing information with each other how to send e-mail, connect to other computers, send and receive files, discuss certain topics on the newsgroup and others

   Equally as important as hardware in the operation of computers is software. This term refers to the programs and procedures that make it possible to use the computer. A Program is a detailed set of instructions that tells the computer what to do, how to do it, and the proper sequence of steps to follow. Programs are written in special computer languages by trained people called computer programmers.Programmers must be familiar with the computer language used in each program. There are a number of different computer languages used in data processing;COBOL (Common Businesss Oriented Language) is the one used most frequently in business computer applications.
    If the architect had to start from scratch. Writing all software, he would be a mason not an architect. Two important trends brighten the picture. First,some very powrful languages such as PASCAL,and Euclid are becoming available on small and inexpensive machines,formerly,small machines had only something like basic plus available. Now sophisticated system languages are becoming common on small as well as on large systems. The second trend is the conversion of powerful operating system, developed for larger (i.e.more expensive) machines,to smaller systems. By providing the operating system,the software engineer givesthe a powerful environment.
   A host use full software tools have also been developed over the years by generations of users. The architect may have to do some searching to find the software, or design some enhancements to adapt the software to his environment,but he should not have to write a software support system from the scratch, althrough he should be capable of choosing, installing, modifying, and operating the system.

The Role Of Computers In Business

   Now days the role of computers is very important in the world business. For example payroll is just one of many routine computer operations. There has been a rapid increase of computer usage into almost every aspect of business; and even assistance in problem-solving and decision making.
   Computers handle large amounts of date rapidly and can effciently categorize, process, and report information for a variety of business operations. Computers, in fact, have a virtually unlimited capacity for processing business data.However, since computers can't think, their role in business is limited to those areas in which they can process information more effectively then human beings. At the administrative level, managers decide how computers and human beings can be used moct effectivaly to perform a particular business task.
   Computers have become an integral part of daay-today business transactions as well as analytic tools for long-range planning, research, and development.Even a small business can utlize computers by either purchasing a small unit know as a minicomputer, leasing one, or by time-sharing. In a time-sharing system, each user is regulary and individuals (for example, college students, engineers, and lawyers)participate in time-sharing computer system.

   Today ,the computer plays avital role in the lives of many Americans and is seeen as one of greates technolgical developments of all times.
   Basically a computers is an electronic machine that is capable of performing mathematical task to slove scientific or clerical problems in a relativey short period of time.There are to main elements of any compter system. They are hardware and software element. Hardware is the physical equipment ,i.e.the machinery and electronic components. Certain task are performed by the hardwar. In very simple terms,these tasks can be described in following.
   Properly prepared pieces of information known as dates are into the computer is called input. They put away for future use that is called storage,and handled for a specific purpose is called manipulation. Finally,the result are made available to the users is called output. The combination of these tasks is known as data procssing .

A computer is a machine with an intricate network of electronic that operate switches or a magnetize tiny metal cores.The switches,like the cores are capable of being in one of two possible states that is on or off magnetized or demagnetized.The machine is capable of storing and maniplating numbers lettters ad characters.The basic idea of computer is that we can take the machine for what we want by inputting signals that turn certain switches on and turn the others off,or that magnetize or do not magnetize the cores.
The basic job of compiters is the processing of information. For the reason computers can be defined as devices which accept information in the from of instruction called a program and characters called data perform matheamatical and/or logical operations on the information ,and than supplay result of these opertoion.The program tells the computers what to do and the data,which provide the information needed to slove the problem,are kept inside the computers in a plcae called memory.

The objective of information system is to provide information to all levels of management at the most relevant time, at an acceptable level of accuracy,and at an economical cost.

These produce the working documents of the business, such as invoices and statments. These are the first systems which a company will install. Above thre transactions level systemare decision support systems. These take external information, market trends and otherexternal financial data, and processed internal information, such as sales trends, to produce strategic plan, forecasts, and budgets. Management information system lie at the top of the hierarchy of information need. The MIS takes the plan and information from the transaction level system to monitor the performance of the business as a whole.
