Computer System.ppt Watchamacallit?! : Watchamacallit?! Hardware Computer System.ppt Information - the physical components of the computer, including the computer itself and matched peripherals. Software - the programs that run the computer. Data - are facts, or unorganized raw materials, which can be made up of words, numbers, images, or sounds. – data that has been processed. Watchamacallit?! : Watchamacallit?! Bit - the smallest unit of data that a computer uses. It can be used to represent two states of information, such as Yes or No. Computer System.ppt Byte - is equal to 8 Bits. A Byte can represent 256 states of information, for example, numbers or a combination of numbers and letters. 1 Byte could be equal to one character. Bits on Bytes : Bits on Bytes 1 byte = 8 bits 1 kilobyte (K / Kb) = 1,024 bytes 1 megabyte (M / MB) = 1,048,576 bytes 1 gigabyte (G / GB) = 1,073,741,824 bytes 1 terabyte (T / TB) = 1,099,511,627,776 bytes Computer System.ppt How big is BIG?? : How big is BIG?? Fact 1: Kilobyte 1 Kilobyte would be equal to this paragraph you are reading, whereas 100 Kilobytes would equal an entire page. Computer System.ppt How big is BIG?? : Fact 2: Megabyte One of those old 3-1/2 inch floppy disks can hold 1.44 Megabytes or the equivalent of a small book. How big is BIG?? Computer System.ppt How big is BIG?? : Fact 2: Megabyte 100 Megabytes might hold a couple volumes of Encyclopedias. Computer System.ppt 6 650 Megabytes is about the amount of data that will fit on a CD-ROM disk. How big is BIG?? How big is BIG?? : Fact 3: Gigabyte 1 Gigabyte of data is almost twice the amount of data that a CD-ROM can hold. How big is BIG?? Computer System.ppt 1 Gigabyte could hold the contents of about 10 yards of books on a shelf. 100 Gigabytes could hold the entire library floor of academic journals. How big is BIG?? : Fact 4: Terabyte To put it in some perspective, a Terabyte could hold about 3.6 million 300 Kilobyte images or maybe about 300 hours of good quality video. A Terabyte could hold 1,000 copies of the Encyclopedia Britannica. Ten Terabytes could hold the printed collection of the Library of Congress. How big is BIG?? Computer System.ppt HARDWARE : HARDWARE Computer System Components : Input Devices – enable users to get data into the computer for processing Computer System Components Input - getting data into the computer Computer System.ppt Computer System Components : Microprocessor is simply a small processor fabricated on a chip of silicon Computer System Components Processing - transforming data into information Computer System.ppt Computer System Components : Output devices – enable users to see and/or produce processed informations Computer System.ppt Computer System Components Output – displaying the information Slide 15: Computer System.ppt SOFTWARE : SOFTWARE What is a Software? : What is a Software? Software – refers to any program that tells the computer system what to do. Computer System.ppt Categories of Software : Categories of Software System Software – programs that take control of the PC on start-up, and then play a central role in everything that happens within a computer system by managing, maintaining, and controlling computer resources. Application Software – designed and created to perform specific personal, business, scientific processing tasks. Computer System.ppt System Software : System Software Operating System (OS) Monitors and controls all input / output and processing activities within a computer system. It is a program that controls the PC hardware and the operation of all other programs Computer System.ppt PC Platforms : Platform is defined by a processor and an operating system. PC Platforms Computer System.ppt Software created to run a specific platform won’t run on other platforms. Most personal computer users choose the Wintel platform, which combines one of the Microsoft Windows operating system with an Intel-compatible processor. PC Platforms : PC Platforms Modern Wintel platforms, such as Windows ME and Windows 2000, are backward compatible, allowing programs written for earlier Microsoft platforms to be run on modern systems. Computer System.ppt PC Platforms : PC Platforms Before choosing a platform, consider the following: Availability of appropriate commercial applications software for the platforms. Compatibility of platform with existing hardware, software, and expertise Computer System.ppt Application Software : Application Software Word Processing – a text editing program, which allows the user to type, compose and correct manuscripts without the need to re-type, when errors changed. Computer System.ppt Application Software : Application Software Types of Word Processors WordStar Word perfect Microsoft Word Computer System.ppt Application Software : Application Software Electronic Spreadsheet – is a program replacing the traditional financial modeling tools that offer modern improvements in ease of creating, editing, and using of financial models and graphical representations. Computer System.ppt Application Software : Application Software Kinds of Electronic Spreadsheet Lotus 1-2-3 MS EXCEL QUATTRO FRAMEWORK Computer System.ppt fin : fin This presentation is available now at the yahoo group You do not have the permission to view this presentation.
