Basic Network CompTIA A+ Guide to Managing & Maintaining Your PC By: JEAN ANDREW Chapter 1: Introduction of Computer Software and Hardware 1 Objectives Purpose and Uses of Personal Computer Local and Network Applications Identify the Motherboard, CPU, RAM, Power Supply, and Case. Identify the type of Adapter Cards Identify the type of Storage Devices Identify the type of Portable Devices Identify the type of Peripheral Devices 2 Purpose and Uses of Personal Computers Computers are used all over the world and in all types of environments. They are used in businesses, manufacturing environments, homes, government offices and non-profit organizations. 3 Purpose and Uses of Personal Computers Hardware - the physical components, both internal and external, that make up a computer. Operating System - a set of computer programs that manages the hardware of a computer. An operating system controls the resources on a computer, including memory and disk storage. An example of an operating system is Windows XP . Application Software - programs loaded on the computer to perform a specific function using the capabilities of the computer. An example of application software is a word processor or a computer game. 4 Purpose and Uses of Personal Computers 5 Local and Network Applications Local application - A local application is a program, such as a word processor, that is stored on the hard disk of the computer. The application runs only on that computer. Network application - A network application is one that is designed to run over a network, such as the Internet. A network application has two components, one that runs on the local computer and one that runs on a remote computer. Email is an example of a network application. 6 Identify the Motherboard, CPU, RAM, Power Supply, and Case Hardware Components 7 Motherboard Mainboard is a large circuit board used to connect the electronics and circuitry Required which comprise the computer system. Mainboard contain connectors which allow major system components such as CPU , RAM ,HardDisk ,Power Supply,CDRom/DVD . 8 Motherboard Components 9 CPU (Central Processing Unit) The CPU or Processor , is the nerve center of computer system. It is the component that processes all of the data. 10 RAM (Random Access Memory) RAM use for store memory Temporary. Type RAM such as SDR RAM,DDR(DDR,DDR2,DDR3) SDR RAM 11 ROM (Red Only Memory) ROM use for store memory permanent. It have in BIOS. 12 Power Supply Power Supply is used to deliver power to all devices. 13 Storage Devices Reads or writes information to magnetic or optical storage media. It have such as : Hard Disk Drives Floppy Drives Zip Drives Tape Drives External Hard Disk Flash Drive CD/DVD 14 Adapter Cards Adapter cards add functionality to a computer system. They are designed to be plugged into a connector or slot on the mainboard. Adapter cards includes : VGA Cards Sound Cards Network Interface Cards (Network Card) Modem Controller cards 15 Adapter Cards 16 Portable Devices There Portable devices very small in size, power and graphic include : Notebook PC Pocket PC PDA (Personal Digital Assistant) Gaming Device Cell Phone 17 Portable Devices 18 Peripheral Devices Peripheral is a device that is added to the computer to expand its capabilities. It have such as printer, scanner, modem. 19 Peripheral Devices Importance of UPS and Surge Protector. 20 Summary Computers are used all over the world and in all types of environments including: government, medical, education, manufacturing, legal and leisure. In order for most computers to perform useful functions, there are three things that have to work together: Hardware, Software and Operation Systems. An application can be classified as local or networked . Things to consider when purchasing a computer: Motherboard, CPU, RAM, Adapter Cards, Storage, Peripherals, UPS, Surge Suppressors. There are many different types of Portable Devices available including: Notebook PC, Pocket PC, PDA (Personal Digital Assistant) ,Gaming Device and Cell Phone. 21.
