  11. 11. CS110 Microcomputer applications – G. Sindoni<br />11<br />What is Information & Communication Technology (ICT)? <br />Processes and technologies to create, gather, process, store, disseminate and share information.<br />Definitions:<br />Communication: the activity of conveying meaningful information.<br />Information: an ordered sequence of symbols that records or transmits a message.<br />Technology: application of science, especially in industry and business.<br />
  12. 12. CS110 Microcomputer applications – G. Sindoni<br />12<br />What is a Computer?<br />An electronic device designed to receive and process data and display the results<br />Computer = Electronic Digital Processer<br />Processer: a machine able to store and process data following a sequence of instructions (program). <br />Electronic: a computer uses electronic components.<br />Digital: a computer processes and stores digital signals made of binary digits (0 and 1). Combinations of bits represent words, sounds, videos, etc.<br />Decisive factors in the development and spread of computers:<br />Miniaturization and reduction in price of electronic components<br />Easier user interfaces<br />Increasing popularity of Internet and the Web<br />
  13. 13. CS110 Microcomputer applications – G.

  17. 17. CS110 Microcomputer applications – G. Sindoni<br />17<br />Main components of a PC<br />In the case:<br />Motherboard: printed circuit board containing:<br />Central Processing Unit (CPU): the key component, which interprets and executes program instructions.<br />Main memory: the memory used during processing (RAM)<br />Support chips (ROM BIOS, Clock)<br />Mass storage (permanent memory): hard disks<br />Ports for connection to external devices<br />Out of the case:<br />Input devices providing instructions and data to be processed <br />Output devices transferring results from computer to user. They allow users to see, listen to, and print the results <br />
  18. 18. CS110 Microcomputer applications – G. Sindoni<br />18<br />Central Processing Unit<br />Central Processing Unit (CPU): microprocessor, the computer’s “brain”<br />Executes instructions from programs loaded in the main memory (RAM)<br />Two main manufacturers: Intel and AMD‏<br />Processor speed: <br />Embeddedclocksmeasure the computer “heartbeats": a heartbeat corresponds to a cycle, approximately one processing step<br />Measured in Hertz (cycles per second). 1 MegaHertz = 1 million cycles per second<br />Today’s CPUs: thousands of Mhz (GigaHertz)<br />Today’s PCs: 800 Mhz to 4 Ghz<br />Comparability: CPU speed can only be compared among computers of the same type<br />

  22. 22. CS110 Microcomputer applications – G. Sindoni<br />22<br />Output devices<br />Monitor: main user interface.<br />Size measured as the length in inches of the diagonal dimension. The most common size is currently 17”. <br />Resolution: number of pixel (points). The most common resolution is currently 1024x768 pixels.<br />The video card connects the computer to the screen. Its performance is very important.<br />Monitor types: CRT (Cathode-Ray Tube), LCD (Liquid Crystal Display).

  23. 23. CS110 Microcomputer applications – G. Sindoni<br />23<br />Data storage - 1<br /><ul><li>Computers use digital signals: data are represented by the digits “0” and “1”
  24. 24. Unit of information is the BIT(Binary digIT), which can have 2 states: 0 or 1 (on/off)</li></ul>OFF ON<br />An 8-bit group is a Byte, the conventional unit of measurement for data quantity. Byte multiples:<br />1 Kilobyte(Kbyte or Kb) = 210 Byte = 1,024 Bytes<br />1 Megabyte (Mbyte or Mb) = 210 Kbyte = 1,048,576 Bytes<br />1 Gigabyte (Gbyte or Gb) = 210 Mbyte = 1,073,741,824 Bytes<br />1 Terabyte (Tbyte or Tb) = 210 Gbyte = 1,099,511,627,776 Bytes<br />
  25. 25. CS110 Microcomputer applications – G. Sindoni<br />24<br />Data storage - 2<br />ASCII (American Standard Code Information Interchange) coding: a byte represents a number or a letter.<br />Needed to represent characters (letters, numbers and symbols) using the binary system. <br />Now being replaced by UNICODE, which uses at least 16 bits (2 bytes)<br />
  26. 26. CS110 Microcomputer applications – G. Sindoni<br />25<br />Main memory<br />RAM (Random Access Memory): the memory used for data processing.<br />Data and programs loaded into the RAM as they are used by the processor.<br />Random access to memory cells, the most efficient way. <br />RAM is temporary. When the computer is switched off, RAM is erased: very important to save current work.<br />Current sizes: from 1 to 4 Gigabytes for PCs, but this can be expanded. <br />
  27. 27. CS110 Microcomputer applications – G. Sindoni<br />26<br />Mass storage<br />Permanent devices where data are stored. <br />The main storage device is the Hard Disk(HD):<br />Sizes currently from Gigabytes to Terabytes. <br />Contains the operating system, application programs, documents and personal data. <br />Magnetic devices: organization. Formatting. <br />Internal and external HDs.<br />Other units (backup): tape units for server backups.<br />Optical devices: Compact Disc (CD) and Digital Versatile Disc (DVD)<br />CD (up to 800 Mbyte), DVD (up to 17 times more). <br />CD and DVD: ROM (read only memory), R (recordable) and RW (rewritable). <br />CD/DVD drive needed to read contents.<br />Burner needed to save (write) to CD/DVD.<br />Rewritable memories (Flash): compact flash, USB drive, SD (Secure Digital), MMC (MultiMedia Card).<br />Network disks (NAS: Network Attached Storage)<br />

  29. 29. CS110 Microcomputer applications – G. Sindoni<br />28<br />Computer performance<br />Depends on many factors:<br />Clock frequency (MegaHertz, GigaHertz). Comparable only between “families” of similar processors.<br />Internal architecture: speed of motherboard and other parameters.<br />Available RAM.<br />Disk access speed and capacity.<br />Video‏ card speed.<br />
