Web browser, linux, bit & bytes, files

  1. 1. REVIEW
  2. 2. TRUE OR FALSE <ul><li>Software is a single program or a collection of programs which performs many task and/or system related functions. </li></ul><ul><li>Software is the detailed instructions that control the operation of hardware. </li></ul><ul><li>Without software, hardware can not extend its capabilities or utilities. </li></ul>
  3. 3. TRUE OR FALSE <ul><li>Software manage the computer resources of the organization. </li></ul><ul><li>Software provide tools for human beings to take advantage of these resources. </li></ul><ul><li>Software act as an intermediary between organizations and stored information. </li></ul>
  4. 4. TRUE OR FALSE <ul><li>Software is intangible. </li></ul><ul><li>Software is easy to reproduce. </li></ul><ul><li>Untrained people can hack something together. </li></ul><ul><li>Software is easy to modify. </li></ul>
  5. 5. IDENTIFY THE FOLLOWING SOFTWARES ACC. TO TYPE <ul><li>COBOL </li></ul><ul><li>MAC OS </li></ul><ul><li>PASCAL </li></ul><ul><li>MS WORD </li></ul><ul><li>WINDOWS XP </li></ul><ul><li>MS EXCEL </li></ul><ul><li>WORD PERFECT </li></ul><ul><li>UNIX </li></ul><ul><li>MS POWERPOINT </li></ul><ul><li>OPENOFFICE WRITER </li></ul><ul><li>C AND CC+++ </li></ul><ul><li>MS DOS </li></ul><ul><li>WINDOWS 7 </li></ul><ul><li>OPEN OFFICE IMPRESS </li></ul><ul><li>LINUX </li></ul>
  6. 6. WEB BROWSER, LINUX, BITS AND BYTES, AND FILES
  7. 7. WEB BROWSER <ul><li>-IS A PROGRAM THAT YOU USE TO VIEW WEB PAGE. </li></ul><ul><li>Examples </li></ul><ul><li>A. Internet Explorer </li></ul><ul><li>B. Netscape Navigator </li></ul><ul><li>C. Mozilla FireFox </li></ul>
  8. 8. LINUX <ul><li>IS A FREE UNIX-TYPE OF OPERATING SYSTEM ORIGINALLY CREATED BY LINUS TORVALDS WITH THE ASSISTANCE OF DEVELOPERS AROUND THE WORLD. DEVELOP UNDER THE GNU General Public License- the source code for Linux is freely available to everyone. </li></ul>
  9. 9. BITS AND BYTES <ul><li>The computer only understand two things, those two things are. </li></ul><ul><li>ON- is represented by the number 1. </li></ul><ul><li>OFF-is represented by 0. </li></ul><ul><li>This is based on the BINARY NUMBER SYSTEM, this digits are known as bits. </li></ul>
  10. 11. <ul><li>Bit:  A bit is a  b inary dig it . It's the most basic unit of information. It has a value of either 0 (zero) or 1 (one). </li></ul><ul><li>Byte:  A group of eight bits. A byte can hold 256 values, from 0 to 255. Generally, a byte holds one character (A through Z, 0 through 9, etc). </li></ul>
  11. 12. BITS AND BYTES <ul><li>BIT- is a contraction of the words… </li></ul><ul><li>B inary d I gi T </li></ul><ul><li>In order for the computer to save information it saves in terms of Bytes. </li></ul>
  12. 13. BITS AND BYTES <ul><li>BYTE- is a contraction of the words… </li></ul><ul><li>B inar Y digi T s E ight </li></ul><ul><li>This means that one byte consists of eight bits. A byte is necessary in order for the computer to store a character of information. So in terms of storage space a byte can be considered to be the size of a character. </li></ul>
  13. 14. <ul><li>Kilobyte:  You guessed it: A thousand (actually, 1024) bytes. </li></ul><ul><li>Megabyte:  A million bytes </li></ul><ul><li>Gigabyte:  A billion bytes </li></ul>
  14. 16. Here's how the decimal base number 217 is represented in binary form. Note that because it's less than 255, it &quot;fits&quot; within a single byte (which contains only 8 bits). Isn't that neat?   The rightmost bit represents 2 to the zero power, or 1. The bit to its left represents 2 to the first power, or 2. The third bit from the right represents 2 squared (2 2 ), or 4. The fourth bit from the right represents 2 cubed (2 3 ), etcetera.   Add all eight values together; the sum is the value of the byte.  
  15. 17. KILOBYTES 1 K 1 Thousand bytes MEGABYTES 1 MB 1 Million bytes GIGABYTES 1 GB 1 Billion bytes
  16. 19. FILES <ul><li>Files are clumps of computer data stored somewhere in your computer. Each file has… </li></ul><ul><li>NAME </li></ul><ul><li>LOCATION </li></ul><ul><li>LENGTH </li></ul><ul><li>DATE </li></ul>
  17. 20. WHAT DO FILES DO? <ul><li>Files hold and store information that can be read by the computer. </li></ul>
  18. 21. KINDS OF FILES Name Inside Does/html .com instructions It runs or execute .exe instructions It runs or execute .txt Readable info. To read .gif Graphical info. To see .htm/html Textual info. To see using a browser.
  19. 22. WHAT DO YOU DO WITH FILES? <ul><li>RUN THEM- if they hold program. </li></ul><ul><li>LOOK INSIDE THEN- if they hold graphics information or text. </li></ul>
