The document discusses the information technology tool of the internet and world wide web. It provides background on information technology and defines hardware and software. It describes the evolution of computer sizes from mainframe to mini to microcomputers and how their roles and capabilities have changed. It also discusses operating system roles, computer hardware components like primary storage, input/output devices, and communication devices.

- 1. Learning Activity 2 THE INFORMATION TECHNOLOGY TOOL (THE INTERNET) AND THE WORLD WIDE WEB Presented to DR. MARILYN M. ESCOBAR EMGT-340 MANAGEMENT INFORMATION SYSTEM (MIS) By AILEEN H. BANAGUAS Ph. D Student Cavite State University July 20, 2013
- 2. Due Date: July 13, 2013 AILEEN H. BANAGUAS Ph.D Student Cavite State University, Indang, Cavite EMGT 340 – MANAGEMENT INFORMATION SYSTEM DR. MAYLIN M. ESCOBAR LEARNING ACTIVITY 1 Computer Hardware and Software: A Quick Tour of Technology Information technology refers to the collection of tools that make it easier to use, create, manage and exchange information. The Internet is the latest of a long series of information technologies, which includes printing, mail, radio, television and the telephone. Hardware is a comprehensive term for all of the physical parts of a computer, as distinguished from the data it contains or operates on, and the software provides instructions for the hardware to accomplish tasks. It consists of programs and applications that run on computers. We’ve already seen how large the computers were and these days we are using very small computers If we look at the computers from this perspective, we can group them into three categories – Mainframe, Mini and Microcomputers.Mainframe are very huge computers. It is very powerful computers with large memory and processing capabilities. It can support hundreds of users simultaneously. Mini computers are medium sized computers, much larger than the personal computers we are using and smaller compared to the mainframe computers. These computers can support multiple users simultaneously and is less powerful than mainframe computers. Microcomputers are often called personal computers (PCs) because they are intended to be used by a single person at a time. While mainframe and mini computers can support multiple users simultaneously, it can support only one user at a time. Micro computers can further be classified into desktop laptops.
- 3. The role of productivity is to assist the people in becoming more productive, effective and efficient. A vertical market is a particular industry or group of enterprises in which similar products or services are developed and marketed using similar methods. Horizontal Software, is application software that is useful in a wide range of industries. Operating system roles may be defined to provide users access to computer resources, such as files, computer setup and configuration tasks, application programs and specific features within applications, separately from the permissions associated with the user's login. Permission levels may be designated directly to roles, providing a level of abstraction beyond user login access permissions. Role members may gain access to a resource through the permissions of a role, and similarly, other authorized users will not be denied access to a resource based on a change to the role. The Computer hardware interprets and executes the program (software) instructions and coordinates how all the other hardware devices work together. Primary Storage, are The computer’s main memory, which consists of the random access memory (RAM), cache memory, and the read-only memory (ROM) that is directly accessible to the central . processing unit (CPU)Input Devices, output Devices, CPU and RAM. The Secondary Storage Equipment designed to store large volumes of data for longterm storage (e.g., diskette, hard drive, memory card, CD. Equipment used to capture information and commands (e.g., keyboard, scanner). Output devices Equipment used to see, hear, or otherwise accept the results of information processing requests (e.g., monitor, printer). Communication devices Equipment used to send information and receive it from one location to another (e.g., modem). END… It’s the journey not just the destination that’s important.
