Introduce to the student the importance 1. of DOS principles for any work on IBM P.C's. B. Instructional Topics and Key Points TOPIC KEY POINT 1. Hardware Definition - Anything you can la. touch. Components of a basic computer lb. system: computer - microprocessor, power supply, data buses, RAM, and ROM. Microprocessor - brains of computer (8086,80286,80386 & also mention math co- processors). Power supply - 3.20VAC to 5 VDC. Data buse9 - serial and parallel. RAK - random access memory, volatile, where your program is stored, measured in kilobytes and megabytes where 1 byte = 1 character = 8 bits. ROK - read only memory, nonvolatile, where a portion of DOS is stored, contents of memory can only be read from and not written to. Keyboard - input device, looks like a typewriter ( explain differences). Monitor- aka screen, VDT, CRT. output device similar to a tv. (explain differences between screen and tv. Printer - output device, makes makes a hardcopy of output to paper. (explain different types of printers). Edsk Drives - nechaniem which allows for the storage and retrieval of files to and from disks. (go over types of disk drives). Also include hard drives. Othet Hardware components: lc. Mouse, digitizer, magnetic tape plotters, light pens, modem, etc. 2. Hardware and soft- Hardware - see la. 2a. ware definitions Software 2b. - a computer program. -3- Instructional Topics and Key Points B. TOPIC KEY POINT 3. Disk Operating 3a. NS-DOS - IRK pc's and clones systems 3b. PC-DOS - IBK pc's and clones (slight differences between it and MS-DOS). 3c. UNIX -another type of DOS. 3d. OS/2 - new DOS for IBM's allows programs to run concurrently. - old DOS. 3e. C1414 4. Bootstrap Procedure 4a. Power is applied. 4b. POST - power on self test. Checks memory and hardware. 4c. A certain portion of OS begins to run. 4d. Tries to find DOS first at A: and then at C: if it can't find (old machines start cassette BASIC; newer machines state "non-system disk error"). 4e. If DOS is found, it is loaded into the top end of RAM. This part of DOS is contained in a file called "command.com". 4f. DOS searches for a file called AUTOEXEC.BAT, and it found, commands wlthin it are executed. 4g, Finally, DOS prompt is executed. 5. DOS Command 5a. Turo types of DOS commands: Types resident - those commands which are contained in command.com; these commands are available to the user at all times. programa - those "commands" which must be loaded into RAM prior to executing. Factors to programs: how big, how often). 6. Common Filenames 6a. Filenames - command.com E and extensions autoexec.bat 6b. Extensions - .BAT - batch files .EXE & .COM - programs .TXT .ME .DOC .DAT - text or ASCII files. 7. Gsaeral Format 7a. <Command-Verb>, parameters, for DOS commands switches. -4- Instructional Topics and Key Points B. KEY POINT r----TopIc 8. Disk and Disk 8a. Three sizes of disks/disk Drives drives: 8 1/2", 5 1/4", 3 1/2". 8b. Two types of disk drives for each slze of disks: high and low density. 9. FORMAT 9a. FORMAT command - program which performs the following functions: 1. Writes empty tracks on disk. 2. Creates an empty directory. 3. Creates a FAT 9b. /S - switch to include system files on disk when formatting (2 hidden files and command.com). 9c. 5 1/4" 360K LO T:40 N:9 1.2M N:15 HI T:80 720K LO 3 1/2" Ns9 T:80 N:18 HI T:80 1.4414 9d. Rules for formatting disks: I. Low density drives can only format a disk to low density; high density drives can format both. 2. A high density drive will format a disk to hi density (default). 3. If a disk is low density in a hi deusity drive, disk will default format to 1.211; can't reformat later on. 10. Disk Handling 10a. Don't bend disks. Techniques 10b. Don't expose disk to extreme temperatures. 10c. Don't wTite on disk with a hard pen or pencil. 10d. Don't touch exposed areas of disk. 10e. Keep disk away from ashes, dust, etc. 10f. Keep disk away from magnetic fields. 10g. Keep disk in protective jacket when not in use. 10h. Do not remove disk from drive when drive red indicator light is illuminated. _5_ Instructional Topics and Key Points B. TOPIC KEY POINT 11. Changing Logical lla. To change from one logical Drives drive to another, at the prompt enter the drive letter followed by a semicolon. 12. DIR Command 12a. DIR - Lists the current or specified directory contents, if any, and the number of free bytes of space on the specified drive. 12b. /P - switch for partial listing. 12c. /W - for width of screen listing. 12d. Accepts wildcards but does not display hidden files. 13. TYPE Command 13a. TYPE - Displays the contents of a ASCII file to the screen. To pause hit pause or CTRL S. 13b. Will work with .RAT files, but not with .COM and .EXE files. 13c. Doesn't accept wildcards. 14. Creating and 14a. HD or MXDIR - makes a Deleting Sub- subdirectory at the specified directories place. 14b. RD or EMIR - removes a subdirectory at the specified place. Can't remove subdirectory unless directory is empty. 15. Changing 15a. CD or CBDIR - Changes from the Directories current directory to the specified directory. 15b. CD\ - puts you @ root. 15c. CD displays the current path. 15d. Include path to specify new a directory. 16. Copying Files 16a. COPY - will copy one or more files from one disk or directory to another. Accepts wildcards. /V - verifies copy /B - ignores ASCII EOF and uses file size instead. _6_ B. Instructional Topics and Key Points TOPIC KEY POINT 16. Copying Files 16b. XCOPY will copy files - (continued) selected by date, archive setting, or directory. /A - only copies files whose archive bit is set. /D - only copies files dated on or after the date specified. /E - copies empty subdirectories to target disk. /P - prompts with Y/N before each copy. /S - Creates subdirectories as needed and copies all subdirectories and contents as required. pauses XCOPY so you can /W insert source and target disks. 16c. DISXCOPY nakes an exact copy of one disk to another. Replaces the contents of the target disk with the contents of the source disk. Al empty tracks on source are also written. - copies only the first /1 side of the disk. 17. Erasing Files 17a. DEL or ERASE - erases on or more files from a disk. Agcepts wildcards. Cannot erase hidden or read-only files. 18. Proper File 18a. Explain the importance of Management proper management techniques Techniques when working with computer files. Such techniques should include grouping of logically related files and programs, backing up files/programs and systems, and removing unwanted or old files. 19. The Prompt Line 19a. Displays where you are in the logical drive and subdirectories. May be turned off. Followed with a > sign. B. Instructional Topics and Key Points TOPIC KEY POINT 20. COMMAND.COM & 20A. CWIMAND.COM - file which AUTOEXEC.BAT contains all of the resident DOS commands. 20b. AUTOEXEC.BAT - file which, if present, will automatically run during the bootstrap procedure. 21. COM: and LPT1: 21a. Standard I/0 devices: 21b. COM: indicates the screen during output, and the keyboard during input. 21c. LPT1: indicate the printer during output. 22. Redirection of 22a. Done with > sign. Standard 1/0 22b. Specifies other places for I/0 to go other than the default places. 23. Batch Files 23a. File which contains DOS commands to execute. Must use extension .BAT. may include comments with REM statements. Can enter a batch file directly from the keyboard, or using EDLIN or some other editor. 24. How to run 24a. Insert disk into drive. an unknown 24b. Do a directory. program 24c. Change to subdirectories as required. 24d. Find documentation files. 24e. Print out documentation files. 24f. Read documentation. 24g. Find program. 24h. Run program. 25. Other DOS 25a. SYS - Transfers the hidden DOS Commands files to a specified disk. 25b. RENAME - Changes the name of the file. 25c. VER - Displays the version number of the DOS presently being run. 25d. CHXDSK - Checks the integrity of a disk or file and displays a status report. - will fix errors if /F detected. /V - will display all file and subdirectory names. -8.
