  • Council Workshop Item
    COUNCIL WORKSHOP ITEM ITEM: Public Safety System Upgrade DATE: July 7, 2002 PREPARED BY: The Technology Commission The Public Safety System Project Team PURPOSE: To seek the Village Council’s approval of the agreement with H.T.E. BID AMOUNT: $1,425,539 (Option One) Recommended $1,168,598 (Option Two) DISCUSSION The task of updating the Village’s public safety system has been on village staff’s desks for several years. In the last year, village staff has evaluated public safety systems from five vendors through an RFP process. Each vendor’s system was evaluated based on a demonstration provided by the vendor. Village staff also contacted other towns that use that vendor’s system, and in some cases, visited other towns to see how the system performed in a live environment. Earlier this year, the staff and the Technology Commission rejected all RFP responses and requested of council that we be allowed to evaluate the possibility of upgrading our current public safety system (H.T.E.). For details, please refer to the report presented to the Village Council on February 12, 2002 (www.vil.downers-grove.il.us/govt/mmemo/02-12- 02/readindex.PDF). As indicated in that report, the project team would now look at upgrading the current public safety system manufactured by H.T.E. Following the same process followed in the RFP portion of the project, the team reviewed H.T.E’s products. Again site visits to other government agencies where H.T.E.’s system is used were conducted. In addition, the Technology Commission helped conduct a financial background analysis on H.T.E.

    Unit I: Computer Fundamentals I) Introduction to Computers What is a computer? A computer is an electronic data processing device, capable of accepting data, applying a prescribed set of instructions to the data, and displaying the processed data in a desired manner as output. Characteristics of a Computer • Automatic • Speed and accuracy of computing • Diligence • Power of remembering ( Mass Storage) • Versatility Basic Computer Organization Almost all computer systems perform following basic five operations 1. Inputting 2. Storing 3. Processing 4. Outputting 5. Controlling The internal architecture of computers differs from one computer model to another; however, the basic organization remains the same for all computers. 1/18 A BLOCK DIAGRAM is shown below which displays the five building blocks (functional units) of a computer. These five units correspond to the five basic operations performed by all computes. Applications of Computers Computers have their application or utility everywhere. We find their applications in almost every sphere of life–particularly in fields where computations are required to be done at a very fast speed and where data is so complicated that the human brain finds it difficult to cope up with. Computer now-a-days are being used almost in every department to do the work at a greater speed and accuracy. They can keep the record of all the employees and prepare their pay bill in a matter of minutes every month. They can keep automatic checks on the stock of a particular item.

  • MICROCOMPUTERS a Microcomputer Is a Small, Relatively
    MICROCOMPUTERS A microcomputer is a small, relatively inexpensive computer with a microprocessor as its central processing unit (CPU). It includes a microprocessor, memory, and input/output (I/O) facilities. Microcomputers became popular in the 1970s and 80s with the advent of increasingly powerful microprocessors. microcomputer contains a microprocessor (a central processing unit on a microchip ),memory in the form of read-only memory and random access memory , I/O ports and a bus or system of interconnecting wires, housed in a unit that is usually called a motherboard . Monitors, keyboards and other devices for input and output may be integrated or separate. Computer memory in the form of RAM, and at least one other less volatile, memory storage device are usually combined with the CPU on a system bus in one unit. Other devices that make up a complete microcomputer system include batteries, a power supply unit, a keyboard and various input/output devices used to convey information to and from a human operator (printers, monitors, human interface devices). Microcomputers are designed to serve only one user at a time, although they can often be modified with software or hardware to concurrently serve more than one user. Microcomputers fit well on or under desks or tables, so that they are within easy access of users. Bigger computers like minicomputers, mainframes, and supercomputers take up large cabinets or even dedicated rooms. A microcomputer comes equipped with at least one type of data storage, usually RAM. Although some microcomputers (particularly early 8-bit home micros) perform tasks using RAM alone, some form of secondary storage is normally desirable.

  • Categorizing Computer Systems
    CATEGORIZING COMPUTER SYSTEMS Section 5 CATEGORIES OF COMPUTER SYSTEMS Contemporary computers can be categorized as mainframes, midrange computers, PCs, workstations, and supercomputers. Managers need to understand the capabilities of each of these types of computers, and why some types are more appropriate for certain processing work than others. Classifying Computers A personal computer (PC), which is sometimes referred to as a microcomputer, is a computer that can be placed on a desktop or carried from room to room. Smaller laptop PCs are often used as portable desktops on the road. PCs are used as personal machines as well as in business. Handheld computers as well as newer pen-based PCs fall into this category. PCs are constantly evolving. For example, the latest generation of tablet PCs recognizes handwriting and handles multimedia much better than previous generations. A workstation also fits on a desktop but has more powerful mathematical and graphics- processing capabilities than a PC and can perform more complicated tasks than a PC in the same amount of time. Workstations are used for scientific, engineering, and design work that requires powerful graphics or computational capabilities. A midrange computer is more powerful, more expensive, and larger than a PC but is capable of supporting the computing needs of smaller organizations or of managing networks of other computers. Midrange computers can be minicomputers, which are used in systems for universities, factories, or research laboratories, or they can be servers, which are used for managing internal company networks or websites. Server computers are specifically optimized to support a computer network, enabling users to share files, software, peripheral devices (such as printers), or other network resources.

  • ITRM Standards Update 2008
    Enterprise Architecture Standard ITRM Standard EA 225-04 Section 7 – ETA Platform Domain Update: October 29, 2007 Section 7. ETA Platform Domain The Platform Domain addresses personal and business computing hardware systems and related software. The hardware platforms include servers, storage systems, server appliances, personal computing devices (desktops, notebooks, and hand-held computing devices), and peripheral devices (e.g., printers). Software is limited to personal computing software, operating systems and utility system software used to meet basic platform infrastructure needs. Software examples include Windows operating system, word processing software, email server software, storage directors, and server backup software. The Platform Domain addresses the hardware and software issues, requirements and recommended practices under three technical topics: personal computing, servers, and utility services. In 2003, the General Assembly mandated that the Virginia Information Technologies Agency (VITA) consolidate information technology infrastructure (platforms and networks) and its management across executive branch agencies except higher education agencies. The General Assembly also placed procurement of information technology under VITA. Because of these changes, VITA is referenced here instead of agencies whenever the requirement addresses a consolidation-related strategy or information technology procurement strategies.
