Today’s Agenda: Computer Basics Review Hardware: The physical components of a computer, any internal or external computer part that you can touch. Software: programs or other "instructions" that a computer needs to perform specific tasks. ( Ex. word processors, web browsers, video games, spreadsheets, operating systems.) Computer- is an electronic device that processes data and converts it into information that people can use. Information- data that is organized, meaningful, and useful manner. Test on Tuesday 5/3

Computer Hardware Some examples of hardware: flash drive head phones keyboard monitor Microphone RAM memory mouse printer scanner Speakers Hard disk Video card

COMPUTER SOFTWARE What is “software?” Software: programs or other "instructions" that a computer needs to perform specific tasks. ( Ex. word processors, web browsers, video games, spreadsheets, operating systems.) What are the major types of software? Application Software: software designed to help the user to perform specific tasks, ex. MS Word Operating System (OS): the programming that makes your computer boot up and run its most basic functions, ex. Windows 7 or Snow Leopard Utility Software: used to perform various tasks like backing up files, or scanning for viruses, ex. Norton Programming Software: used to write computer programs, ex. Scratch, Java

What are the MAIN COMPONENTS INSIDE a COMPUTER? CPU Hard Disk RAM Motherboard Optical Drive Power Supply Video Card

5 What Does A Computer Do? Computers can perform four functions, which comprise the information processing cycle. Input – data is put into the computer Process – data is manipulated Output – data is provided to user Storage – data is stored

Input – enter data or information How do we “input” (put in) information into a computer?

OUTPUT – Computers put out data How do computers output (display) data? "View" Processed Data

STORE – Computers store data (information) Where do computers store information?

PROCESS – Computers manipulate data (information) How do computers process information? CPU

10 What devices are part of a computer system? Printer (output) Monitor (output) Speaker (output) Scanner (input) Mouse (input) Keyboard (input) System unit (processor, memory … ) Storage devices (CD-RW, Floppy, Hard disk, zip, … )

11 Why Is A Computer So Powerful? The ability to perform the information processing cycle with amazing speed. Reliability (low failure rate). Accuracy Ability to store huge amounts of data and information. Ability to communicate with other computers.

12 How Does a Computer Know what to do? It must be given a detailed list of instructions, called a computer program or software, that tells it exactly what to do. Before processing a specific job, the computer program corresponding to that job must be stored in memory. Once the program is stored in memory the compute can start the operation by executing the program instructions one after the other.
