...Course: Date: Chapter Two Journal Entry: Fundamentals of Information Systems Organizations spend huge chunks of money in computer software and hardware installation to ensure that they increase revenue, cut on costs, increase worker productivity and provide a working customer support. Thus, the persons concerned in identifying and selecting computer hardware and software must recognize the business needs of the organization at present and in future. Firms that do not take advantage of advances in information systems will have a weak competitive advantage (Stair and Reynolds 117). The physical components of a computer perform input, storage, processing and output. Since they make up well performing hardware, they must be carefully selected to suit the murky nature of the technology industry and the evolving business needs. As the computer hardware manufacturers implement green computing designs to conserve the environment, hardware requirements will reduce. Similarly, disposal of products relating to information systems ought to be done carefully. Green computing aims to lessen the use of harmful material, allow companies to cut on power costs and ensure safe disposal of waste products. For instance, in a bid to reduce data-storage facilities, developers created cloud data centers. On the other hand, software is vital to controlling the working of computer hardware. An operating system allows users to interact with the computer through tasks and user control access...

...Hardware and software share responsibility for managing I/O operations and devices. Why is this hardware support required for this activity? Answer the question in a journal entry The fundamental operation of the operating system (OS) is to abstract the hardware to the programmer and user. The operating system provides generic interfaces to services provided by the underlying hardware. In a world without operating systems, every programmer would need to know the most intimate details of the underlying hardware to get anything to run. Worse still, their programs would not run on other hardware, even if that hardware has only slight differences. Hardware definition-It refers to the physical elements of a computer. This is also sometime called the machinery or the equipment of the computer. Examples of hardware in a computer are the keyboard, the monitor, the mouse and the processing unit. However, most of a computer's hardware cannot be seen; in other words, it is not an external element of the computer, but rather an internal one, surrounded by the computer's casing (tower). A computer's hardware is comprised of many different parts, but perhaps the most important of these is the motherboard. The motherboard is made up of even more parts that power and control the computer Software definition-It refers to all the electronic instructions that tell the hardware how to perform a task. These instructions come from a software developer in the form that will be accepted by the platform...

...Have you ever wondered how using a computer actually accomplishes tedious tasks? Tasks including connection to the internet, moving a file from one location to another, or having the ability to use a video application that helps interact with family in remote locations. If the needs of a computer were adequate enough to produce one specific function, such as typing, than the technologies we have now would not exist. The computers of today need to perform expeditious data processing for extensive data tasks. That’s approximately three billion calculates per second on just your average household computer. (Tymann 2008). This is all accomplished by programmable chip sets known as central processing units. Programmable codes within the central processing units are known as complex instruction set computing and reduced instruction set computing. Technologies in the present and the future depend on these architectures for expedited growth, without them society will halt in technological advances. These computing architectures provide the foundations of computer processing, although each having their specific advantages, disadvantages, pros, and cons. Information technology is rapidly growing, providing users and businesses a means to share digital data. Businesses gear towards investing money in all aspects of information technology systems to provide services for their customers. Users use computers as a means to communicate with family or watch the latest movie over the internet...

...Hall Prof. White ITE 221 January 18, 2016 Chapter 1 * A computer architecture is basically made up of four different elements. The first one being data(fundamental facts of data and observations), hardware(executes instructions and stores data), software(controls the operations of the system), and communication(capability to share info with other computers). * An IT systems consists of one or more computer systems that go by protocols to communicate messages between one another. Hence Use, URL, Web Browser, Page request message, Communication Channel, PGM, Web Server which all goes back to HTML file. * Work that is performed by an individual computer system is called IPO. It is an input, process, and output. Above the processing system is the storage for the system to keep it. * Input is the data that you yourself put into the computer, output is the data that the computer spits out, Calculations and other operations are operated by the CPU. * Arithmetic/logic unit(ALU) where arithmetic and Boolean logical calculations are performed, Control Unit(CU) movement of internal CPU data from one part of the CPU to the other. Interface Unit moves instructions and data between the Cpu and other hardware. * Overall the chapter discusses the functions of different parts of a computer and what they can do when they can communicate with eachother.

...The information technology course module has been designed with more of software part in the course whereas Computer Science includes more of computer hardware part like networking, chip level knowledge etc. Although some of the subjects are same in both the streams. Answer Information Technology is the business side of computers - usually dealing with databases, business, and accounting. The cs engineering degree usually deals with how to build micro processors, how to write a compiler, and is usually more math intensive than IT. One way to think of it is one is dealing with information - data which would be the IT and the other is dealing with the "science" or "how to make it" of computers. Answer The exact answer depends heavily on the college or university in question, as each tends to split things slightly differently. As a generalization, there are actually three fields commonly associated with computers: Information Technology - this sometimes also goes by the names "Information Systems", "Systems Administration", or "Business Systems Information/Administration". This is a practical engineering field, concerned primarily with taking existing hardware and software components and designing a larger system to solve a particular business function. Here you learn about some basic information theory, applied mathematics theory, and things like network topology/design, database design, and the like. IT concerns itself with taking building blocks such...

...Computer Organization The dictionary definition of the term “organizing” is “to put together into an orderly, functional, structured whole”. Therefore, this term applies to Computer Organization because it tries “to put together into an orderly, functional, structured whole” the main components of computers and the way computers are organized. Modern computer technology requires professionals of every computing specialty to understand both hardware and software. The interaction between hardware and software at a variety of levels also offers a framework for understanding the fundamentals of computing. Whether our primary interacts is hardware or software, Information Technology, Computer Science or Electrical Engineering, the central ideas in Computer Organization is the same. Thus, the emphasis of this is to show the relationship between hardware and software and to focus on the concepts that are the basis for current computers. The computer lies at the heart of computing. Without it, most of the computing disciplines today would be a branch of theoretical mathematics. To be a professional in any field of computing today, one should not regard the computer as just black box that executes program by magic. We, students of computing should acquire some understanding and appreciation of a computer system’s functional components, their characteristics, their performance, and their instruction. There are practical implications as well. In describing computer systems, a distinguishing...

...We live in an advanced age. Some of us can't even remember a time when we didn't use a computer on every basis. Technology has been developing rapidly, compare to the past 20 years. In this new era of technology, computers and laptops have the most critical outcome in our lives. It is changing the way we connect, communicate, share data and interacts. But most importantly, the Operating System has a huge impact on any type of PC and smartphones. According to (Capron, 2001), “An Operating System is the fundamental software that has the access to control all other software and hardware resources” (p. 65). It has control of every file, processes, session of memory and device. (Nickerson, 2001) stated, “The most centralized system software is the OS. Without it, PCs would be extremely hard to utilize.” (p. 31). It is specially designed to work for different types of computers. For example: desktop computer, laptop, tablet PC, handheld PC, etc. Generally, a personal computer (PC) is all-purpose computer. The size and the capabilities make it convenient for individuals, and which is intended to be operated directly by an end user. The different types of operating systems are, Windows, Linux, Mac OS, etc. and each of them have different versions. These advances in hardware and software technologies have increased demands for more advanced and better operating systems.
