The Leader
by Foo Mun Joon
As an ordinary student, life would never live without the Internet. The Internet not merely a place to acquire information and knowledge, it’s also a channel which connects people together. The top site which I most visited is Facebook. The reason is because Facebook not only enable us to communicate and with each others, it also enables us to unwind our stresses because there are a lot of game applications in this site, so it is doubtless that Facebook had became my most visited site. Education is something a student can’t live without. So, UTAR intranet is also one of my most visited site. It is a site which allows students to download lecture and tutorial materials. Besides, it also provides open forum for students and lecturers. They can discuss issues in the forum. This helps students to acquire knowledge more effectively, at the same time; it also helps to enhance the relationship between lecturers and students.
For a business student, having strong general knowledge about the outside world is very vital. Doubtless, updated news is crucially important to me. Star Online has become one of the channels I acquire news from. Unlike newspaper which is inconvenient to carry around, Star Online can easily allows me to update myself with updated news wherever and whenever. I can easily read the news via my mobile device instead of carrying a newspaper with me.

IS Hardware
In information technology, hardware is the physical aspect of computers, telecommunication, and other devices. Hardware implies permanence and invariability. Hardware includes not only the computer proper but also the cables, connectors, power supply units, and peripheral devices such as the keyboard, mouse, audio speakers, printers and others. Hardware is sometimes used as a term collectively describing the physical aspects of telephony and telecommunications network infrastructure.
The Evolution of Computer Systems: Mainframe Computer Systems to Microcomputer Systems
Mainframe
Mainframe is the parent of all computers, which is used mainly by large organizations for critical applications, typically bulk data processing such as census, industry or consumer statistics, and financial transaction processing. Therefore, mainframe can reduces management and administrative costs while providing greatly improved scalability and reliability. Mainframe can replace hundreds of smaller computers because it often supports thousands of simultaneous users who gains access through specialized terminals.
The term originated during the early years of computing and referred to the large mechanical assembly that held that central processor and input or output complex. Since the mid1960's, mainframe designs have included several subsidiary computers which manage the input devices, leaving the CPU free to deal only with high-speed memory. Mainframes commonly have hundreds to thousands of times as much data storage online, and can access it much faster. Mainframe like computing platform, it is dependent on its ability to scale, support mixed workloads, reduce labor costs, deliver uninterrupted service for critical business applications, and several other risk-adjusted cost factors. However, mainframe did not utilize programming languages that were user friendly. It is also huge in size, expensive and difficult to maintain.
IBM 704 Mainframe
Microcomputer
In the mid-1960's minicomputers were selling in the marketplace. Some computers used a micro program, stored in ROM; the inner part of such a computer was called an "engine" or "micro engine" or "microprocessor." In 1970, a microcomputer was normally interpreted as a computer considerably smaller than a mini-computer, possibly using ROM for program storage. By extension, the terms "nano-computer" and "pico-computer" have also been used by computer engineers indicating relative size and performance of computers.
In the late 1960's Fairchild had a logic family called µ-logic, so the prefix was also used for "micro logic". It mentions "the computer on a chip" in 1968, and Scientific American also featured "Computer on a Chip," with 400 gates in 1970. IBM looked for ways of simplifying computers. In 1968, Hitt proposed a 4-b computer with no arithmetic unit and no registers. But this very simple computer was not built and was still called a minicomputer.
The single chip central processor unit (CPU) has been commonly called a microprocessor. With off chip memory, it is usually called a microcomputer. Single chip computers are often called microcontrollers. The 4004 specification was for a microcomputer.
Evolution
In 1940s, the first mainframe computers were developed then several manufacturers also produced mainframe computers.
In 1970s, terminals used for interacting with mainframe systems were gradually replaced by microcomputers. Consequently, demand plummeted and new mainframe installations were restricted mainly to financial services and government.
In the early 1990s, there was a consensus among industry analysts that the mainframe was a dying market as mainframe platforms were increasingly replaced by microcomputer networks. Counselors began to interface with microcomputers much more, it is prompt within the world of business.
As technology advanced the classifications mainframes have become blurred and modern microcomputers are as powerful as the mainframes of twenty years ago.
General Purpose Application Software
Application software, also known as software application, is computer software designed to help the user to perform a singular or multiple related specific tasks. General purpose application software performs common information processing jobs for end users but not in support of a specific purpose. As you can say you can use general purpose application software for more purposes but limited capabilities for each purpose. Because they are significantly increases the productivity of end users, they are sometimes known as productivity packages. General purpose software would be anything that aids in allowing you to accomplish simple computer related tasks. Typical examples are word processors, spreadsheets, media players and database applications.
A spreadsheet is a computer application that simulates a paper, accounting worksheet. It displays multiple cells that together make up a grid consisting of rows and columns, each cell containing either alphanumeric text or numeric values. Spreadsheet program is a general purpose application. It does spreadsheets, but those could be spreadsheets that you use to balance your checkbook, or manage your fantasy football league.
Database software is a database contains a list of information items that are similar in format and/or nature. It is a collection of data for one or more multiple uses. An example is a phone book that lists a name, address, and phone number for each entry. Once stored in a database, information can be retrieved in several ways, using reports and queries. For example, all the names listed for a given area code could be printed out and used for a commercial mailing to that area.
A word-processing software enables you to create a document, store it electronically on a disk, display it on a screen, modify it by entering commands and characters from the keyboard, and print it on a printer. It previously done on typewriters with considerable effort can now be easily completed with word-processing software. Writing tasks such as keying in reports, letters, and tables, as well as merging documents, can be performed easily.
Function-Specific Application Software
Function-specific application software has function to limited end user but they can perform more professional to specific user. It is more limited in what it will do, but it usually goes that one thing much better than a general purpose program. You can use general purpose software for more purposes but limited capabilities for each purpose; but you can use function-specific software for few purposes but with greater capabilities for each purpose. By this function-specific application software is much better then general purpose application software base on application and how it work. For example, business application software, customer relationship management, enterprise resource planning, supply chain management, web-enabled electronic commerce.
TurboTax (a tab preparation package) is a special purpose application. It is one of the most popular income tax preparation software packages. Sure, it adds and subtracts numbers like a spreadsheet, but you can't use it to track your fantasy football league. It does one thing - prepare tax returns.
Customer Relationship Management (CRM) is both a business strategy as well as software. It refers to the applications that help organizations perform activities in three aspects: Operational, Collaborative, and Analytical. CRM as a business strategy is the company’s approach on how to handle its customers and in particular its sales, service and marketing operations. CRM software facilitates the companies to efficiently gather customer information, capitalize customer buying behavior, and leverage technology investments by improving the quality of sales and services.
Business application software supports the re engineering and automation of business processes with strategic e-business application like customer relationship management, enterprise resource planning, and supply chain management. Other examples are software packages that Web-enable electronic commerce applications or apply to the functional areas of business like human resource management and accounting and finance.
Data mining, enterprise information portals, or knowledge management systems are software empowers managers and business professionals with decision support tools.
Prior the emerging of the data warehouse, files and data were stored and recorded by using a traditional file based system. Traditional file based system is basically a file based system, in which we manually or through computer handle the database such as updating, insertion ,deletion adding new files to database. This processing system is no longer to be used in the industry due to its limitations.
The major threat of traditional file based system is lack of integration, it provides data in independent files made it difficult to provide end users with information for ad hoc requests that required accessing stored in several different files. This will caused a waste of time and resources to acquire a specific file for the end user. Besides, the data stored by using this traditional system will cause redundancy. Which means the same data is duplicated into files in different places or department. Problems will occur when there are data had to be updated.
In order to overcome these problems caused by traditional file based system, a new filing system emerged, which named as Data Based Management System (DBMS). DBMS is a set of software programs that controls the organization, storage, management, and retrieval of data in a database. DBMSs are categorized according to their data structures or types. The DBMS accepts requests for data from an application program and instructs the operating system to transfer the appropriate data. The queries and responses must be submitted and received according to a format that conforms to one or more applicable protocols. When a DBMS is used, information systems can be changed much more easily as the organization's information requirements change. New categories of data can be added to the database without disruption to the existing system.
In a nutshell, with no doubt, this new filing system had overcome the problems which caused by traditional file based system. It allows data to be stored in an efficient and compact manner, so that an organization able to operates more smoothly and more effectively.
A telecommunications network is any arrangement where a sender transmits a message to a receiver over a channel consisting of some sort of medium.
Wired technology has been around for ages. It first became popular in the early 1900's with the introduction of the telephone network. The use of wired connections spawned the creation of other technologies. There have 3 types of telecommunications media which are coaxial cable, fiber-optic cable and twisted-pair wire.Coaxial cable is in sturdy cooper or aluminum wire wrapped with spacers to insulate and protect it. This cable commonly used in television cable.Fiber-optic cable is one or more hair-thin filaments of glass fiber wrapped in a protective jacket. It uses pulses of laser-generated light. Besides, it has faster transmission speeds and freedom from electrical interference.Twisted-pair wire is a copper wire that twisted into pairs. It normally uses for ordinary telephone wire.Transmissions via wired technology are more reliable and faster. It is because wired technology does not affected by signal. Moreover, wired technology are cheaper and easier to install.
Wireless isn't really a new technology. Wireless signals were fist used in transmitting AM and FM to television and radios in the early 1950's. This not strictly a transmission media, but rather technologies in which radio signals are through the air. There are many different wireless technologies such as cordless telephones and cellular telephones which are widely used in personal and business communications. Wireless LANS (wi-fi) are uses wireless radio-wave technology to connect PCs. WiMAX is similar to Wi-Fi, but operates over longer distances and at higher speeds. Besides, bluetooth is also a short-range wireless technology. Terrestrial microwave transmit microwave between buildings and communications satellites space stations send and receives microwave signals with earth-based stations.s Wireless technology is more convenient and it can cover larger range compare with wired technology.

Kwan Sook Kwen
My name is Kwan Sook Kwen and I am writing for our IS blog. I am studying Business Administration in UTAR. Well, now I am experiencing my university life but seem that I am not much enjoying into it. Maybe this is because as an Utarian, a lot of matters out there keep reminding me, I am no longer a child.
I do not have any real hobby. As long as it is interesting, then I will do it more often. But in the recent months, I feel fancy watching movies or dramas. It really makes me feel like experiencing all types of lives in the stories. It shows me whatever that is possible to change in order to become anything you want to be, let give it a try!
The most websites that I visited often are websites like www.facebook.com, www.youtube.com, www.google.com.my, www.utar.edu.my, and www.hotmail.com. Facebook and hotmail are my communication tools which connect with others and knowing the latest information. I like to watch funny video clips very much; it gives me an amaze emotion all day long. Watch through Youtube is the easiest way which I no need to wait so long for the clips yet others do. Google is the search engine which I visit most as it is faster and comfortable to search for information. It always provides appropriate websites for me to search information deeply. Lastly, UTAR website is a necessary for me because a lot of lecture notes need to catch up only in the website but no others. Slowly and it becomes my top most favorites website.
I am now possess new skills and immense knowledge in Information System, modern technologies, computers and communicating skills. And above all of them, provide me the chances to knowing IT world and change myself to suit with it. It’s usually my weakness to learn it like all over again, so still now I am training myself. I personally hope that it will be something I really passion about it and not hold on for only three minutes.
In my life, I have been described as weird, funny, over thinking, odd, random, and cool and whatever it will be. I have been called all these different words as I am changing every day, no matter where I am and who I meet. In many times, I think I was born that way though, and as I grow older and bigger, it developed itself, even becomes more grotesquerie. A few years ago, I found that it’s actually a gift to me, simply changes myself to create happiness and satisfaction in my life. However, fun is all around and perhaps it comes after all those hard times. It will be the greatest things of all if I can do in my way followed by my heart.

Lim Pei Yong
I am Lim Pei Yong. My hometown is Taiping, most of the people call it as “rain town”. I joined UTAR, Kampar since year 2008 after I graduated from my secondary school. I am now studying Bachelor of Business Administration in year 1 semester 3.
I am pretty like travelling because when I reach somewhere that I never go before, I can enhance my eyereach by experience their local citizens’ culture and custom. Besides, I extremely like shopping. Because shopping can make me temporary forget any worries in my life. In my dictionary, without shopping, the world is colorless and dark. I like listening music too. When I am moody and feel tension, I would prefer to listen music because it can relax my mind and mood.
The top 5 websites I visited the most are www.google.com , www.facebook.com, www.hotmail.com, www.utar.edu.my and www.blogspot.com. Google is the top international website that use by people to search information. Therefore, I access Google to search information for my assignments and sometimes for my homework. I like Google because its coverage is wide and thus always can provide me much useful information fast and accurate. Currently, facebook is the hottest social communication network especially for the youngsters like us. Certainly, I visit it to keep in touch with my school friends and even with my old friends that are lost contact long time ago. Through facebook, I can know their latest conditions by see about their updated status and life photos uploading by them. We can leave comments and chatting with each other to share our mood and opinions. Furthermore, I often visit my hotmail to check my mails which send by my friends. It’s just like our hand phone short messaging service (SMS). The difference is SMS needs cost charges whereas email is free. Hotmail makes me easy to add new connections. New incoming email messages from my connections and other contacts appear left on my mail home page. I can also filter the messages in my inbox or any other folder to see just those from my connections or from my contacts. Next, I frequently log in to UTAR websites to know current news and even upcoming events that held by our campus so that I can keep in touch with the updated news of UTAR. Via UTAR websites, I can access into the academics, library, ICT facilities, job vacancy and more about UTAR stuffs. Sometimes, I need to log in to UTAR portal to view my billing records and my personal students account to know my examination results. I am not consider an active blogger but occasionally I like to read friends’ blogs to know their currently conditions. People like to share their happiness and sadness in their blog so sometimes I will leave some comments for them if possible.
The top five internet activities that I do are chatting with my friends and family, sending email, search information for my school works, downloading lecturer materials and sometimes read the news around the world.

DBMS is a set of software programs that controls the organization, storage, management, and retrieval of data in a database. DBMSs are categorized according to their data structures or types. The DBMS accepts requests for data from an application program and instructs the operating system to transfer the appropriate data. The queries and responses must be submitted and received according to a format that conforms to one or more applicable protocols. When a DBMS is used, information systems can be changed much more easily as the organization's information requirements change. New categories of data can be added to the database without disruption to the existing system.
In a nutshell, with no doubt, this new filing system had overcome the problems which caused by traditional file based system. It allows data to be stored in an efficient and compact manner, so that an organization able to operates more smoothly and more effectively.
NETWORK COMMUNICATION
Week 7
A telecommunications network is any arrangement where a sender transmits a message to a receiver over a channel consisting of some sort of medium.
Wired technology has been around for ages. It first became popular in the early 1900's with the introduction of the telephone network. The use of wired connections spawned the creation of other technologies. There have 3 types of telecommunications media which are coaxial cable, fiber-optic cable and twisted-pair wire.Coaxial cable is in sturdy cooper or aluminum wire wrapped with spacers to insulate and protect it. This cable commonly used in television cable.Fiber-optic cable is one or more hair-thin filaments of glass fiber wrapped in a protective jacket. It uses pulses of laser-generated light. Besides, it has faster transmission speeds and freedom from electrical interference.Twisted-pair wire is a copper wire that twisted into pairs. It normally uses for ordinary telephone wire.Transmissions via wired technology are more reliable and faster. It is because wired technology does not affected by signal. Moreover, wired technology are cheaper and easier to install.
Wireless isn't really a new technology. Wireless signals were fist used in transmitting AM and FM to television and radios in the early 1950's. This not strictly a transmission media, but rather technologies in which radio signals are through the air. There are many different wireless technologies such as cordless telephones and cellular telephones which are widely used in personal and business communications. Wireless LANS (wi-fi) are uses wireless radio-wave technology to connect PCs. WiMAX is similar to Wi-Fi, but operates over longer distances and at higher speeds. Besides, bluetooth is also a short-range wireless technology. Terrestrial microwave transmit microwave between buildings and communications satellites space stations send and receives microwave signals with earth-based stations.s Wireless technology is more convenient and it can cover larger range compare with wired technology.
