BASIC MICROCOMPUTER COMPONENTS II. OPERATING SYSTEM OPTIONS III. SELECTING A MICROCOMPUTER SYSTEM GLOSSARY OF MICROCOMPUTERTERMS INTRODUCTION The purpose of the Criminal Justice Microcomputer Guide and Software Catalogue is to assist small- or medium-sized criminal justice agencies, unfamiliar with computer technology, in the selection of an appropriate microcomputer system. Which is the best microcomputer system for your agency? Of course, you want the one that matches your agency's data processing requirements. But how do you know which is the best microcomputer system? The answer to that question is the focus of this book: getting the best system (both hardware and software) for your agency is the result of an org.fmized selection process. The Guide suggests a sequence of steps and provides enough information .for you to establish your own systematic approach to acquiring a microcomputer system. To select the best microcomputer system, you need a basic understanding of the parts of a microcomputer system and how those parts work together. This does not mean that you have to be a technical wizard or that you must understand the circuitry of a silicon chip. You do need to know what happens in the process - we put data into the computer, it undergqes a process of manipulation, and information comes out, answering the problem that we wanted to solve. The explanation of this process and the related questions surrounding microcomputer technology are based on SEARCH's many years of experience training criminal justice professionals in the basics of computer technology. The oft repeated questions posed in our national training classes, and the requests we receive from thousands of technical assistance calls, contributed greatly to the content and format of this publication. The publication is divided into two major parts: Pait One, the Microcomputer Guide, defines the basic components of microcomputers and describes a process for selecting a system. Part Two, the Software Catalogue is a listing of operational criminal justice software applications. The first chapter in Part One begins with a discussion of the basic components of a system - its hardware and software. The chapter briefly describes the computer's microprocessor and memory; input devices (keyboards, mouse and light pens); output devices (printers and monitors); and storage devices (hard and floppy disks and magnetic tape drives). Additional hardware components are discussed under communication devices and local area networks. The first chapter continues with a discussion of system software, including operating systems, utilities, languages and industry standards, and general and highly specialized application software. The chapter also includes a brief explanation of public domain software. ix Once you understand the various microcomputer components, Chapter Two, Operating System Options, moves into a detailed review of four general types of operating systems: 1) single-user, single-tasking; 2) single-user, multitasking; 3) multiuser, single-tasking; and 4) multiuser, multitasking. Each type of operating system offers different capabilities and has specific limitations. Your choice of operating system will determine which hardware components you will be able to link together and which application programs you can operate. Putting the right parts together is the key to success. Chapter Three, Selecting a Microcomputer, highlights the general steps in a systematic acquisition process. Your agency's needs determine the best system for you. Your first step in the process, therefore, must be to define those needs. What do you really want the microcomputer to do for you? How is your current system managing (or mismanaging) the defined tasks? After outlining the key points in a needs assessment, the chapter sets out a process for analyzing, evaluating and scoring software packages and hardware components that should help you navigate your way through dozens of potential systems. Chapter Three also helps you to evaluate computer vendors and the services they provide. Throughout the text, technical jargon is kept to a minimum; we hope to provide only the amount of technical terminology you will need to be conversant in the selection process. To guide the reader whenever technical words do appear, they are in boldface type the first time they are used. All words in boldface are defined in the extensive glossary which follows Part One. There are also many additional technical words in the glossary that you may find helpful as you wind your way through the acquisition process. Finally, with an understanding of computer basics, configuration options, and an organized selection process, you will be able to turn to the software listings in Part Two, the Software Catalogue where over 150 existing proprietary and public domain criminal justice software packages offer the promise of addressing your agency's computer needs.

The aim of this thesis is to identify a suitable communication technology for server and smartphone communication which fulfills the main requirements for transferring real- time data to the handheld devices. For the analysis I selected 3 popular communication technologies that can be used on mobile devices as well as from commonly used browsers. These are client polling, long polling and HTML5 WebSocket. For the assessment I developed an Android application that receives real-time sensor data from a WildFly application server using the aforementioned technologies. Industry specific requirements were selected in order to verify the usability of this communication forms. The first one covers the message size which is relevant because most smartphone users have limited data plan.

Memoir by Douglas S. Gale Preface and Introduction Bill Arms and Ken King have chronicled much of the early history of academic computing. Accordingly, I have tried to focus my contribution to The Early Years of Academic Computing on topics less covered by King and Arms. My contribution is organized into four chronological periods, roughly spanning the last 50 years of the 20th century, and each has an organizational theme: career transitions, the microcomputer revolution, the networking revolution, and the changing role of academic computing and networking. The theme of the first period -- career transitions -- will consider where the early practitioners of academic computing came from. Computer Science was first recognized as an academic discipline in 1962, and the early years of academic computing were led by people who had received their academic training in other disciplines. Many, if not most, came from the community of computer users and early adopters.

  • Classification of Computers
    Chapter-2 Classification of Computers Computers can be classified many different ways -- by size, by function, or by processing capacity. Functionality wise 4 types a) Micro computer b) Mini Computer c) Mainframe Computer d) Super Computer Microcomputers Microcomputers are connected to networks of other computers. The price of a microcomputer varies from each other depending on the capacity and features of the computer. Microcomputers make up the vast majority of computers. Single user can interact with this computer at a time. It is a small and general purpose computer. Mini Computer Mini Computer is a small and general purpose computer. It is more expensive than a micro computer. It has more storage capacity and speed. It designed to simultaneously handle the needs of multiple users. Mainframe Computer Large computers are called Mainframes. Mainframe computers process data at very high rates of speed, measured in the millions of instructions per second. They are very expensive than micro computer and mini computer. Mainframes are designed for multiple users and process vast amounts of data quickly. Examples: - Banks, insurance companies, manufacturers, mail-order companies, and airlines are typical users. Super Computers The largest computers are Super Computers. They are the most powerful, the most expensive, and the fastest. They are capable of processing trillions of instructions per second. It uses governmental agencies, such as:- Chemical analysis in laboratory Space exploration National Defense Agency National Weather Service Bio-Medical research Design of many other machines Limitations of Computer Computer cannot take over all activities simply because they are less flexible than humans.

  • From Social Welfare to Social Control: Federal War in American Cities, 1968-1988
    From Social Welfare to Social Control: Federal War in American Cities, 1968-1988 Elizabeth Kai Hinton Submitted in partial fulfillment of requirements for the degree of Doctor of Philosophy in the Graduate School of Arts and Sciences COLUMBIA UNIVERSITY 2013 © 2012 Elizabeth Kai Hinton All rights reserved ABSTRACT From Social Welfare to Social Control: Federal War in American Cities, 1968-1988 Elizabeth Hinton The first historical account of federal crime control policy, “From Social Welfare to Social Control” contextualizes the mass incarceration of marginalized Americans by illuminating the process that gave rise to the modern carceral state in the decades after the Civil Rights Movement. The dissertation examines the development of the national law enforcement program during its initial two decades, from the Omnibus Crime Control and Safe Streets Act of 1968, which established the block grant system and a massive federal investment into penal and juridical agencies, to the Omnibus Anti-Drug Abuse Act of 1988, which set sentencing guidelines that ensured historic incarceration rates. During this critical period, Presidential Administrations, State Departments, and Congress refocused the domestic agenda from social programs to crime and punishment. To challenge our understanding of the liberal welfare state and the rise of modern conservatism, “From Social Welfare to Social Control” emphasizes the bipartisan dimensions of punitive policy and situates crime control as the dominant federal response to the social and demographic transformations brought about by mass protest and the decline of domestic manufacturing. The federal government’s decision to manage the material consequences of rising unemployment, subpar school systems, and poverty in American cities as they manifested through crime reinforced violence within the communities national law enforcement legislation targeted with billions of dollars in grant funds from 1968 onwards.
