False, the bigger the word size the faster the computer can process a set of data. Common word sizes inclued; 16, 32, 64 and 128 bits

• RAM  (random access memory)
• Virtual memory
• ROM  (read-only memory)
• CMOS.
• Cache memory

RAM

-some important facts

RAM acts as temp. storage for:

1. user data

2. operating system instructions

3. program instructions

- RAM is volatile, it must be reloaded each time the computer is turned on

- you can purchase additional RAM for more memory

-there are SIMMS/DIMMS = single in-line memory modules/dual in-line memory modules

With more RAM, the computer has to swap less. The hard disk is much slower than RAM, so less swapping makes for a faster/slower computer?

**pick the correct one

ROM

-imp. facts

-read-only memory

-set of chips that contain permanently stored instructions

- tells the computer how to access disk drives and locate operating system

-used when you turn on comp.

CMOS memory

-imp. info.

-a chip that semi-permanently contains data about the computer configuration

-powered by battery to retain its contents

-can be altered as system configuration change

what are the levels of storage?

cost

speed

volume

mobility

memory

floppy/hard disk

CD-Rom

solid state storage flash memory

what is RAID

....and no, its not that shit you use to kill bugs :p

-redundant arrays of inexpensive disks

-used to record redundant copies of information on seperate disks (called disk mirroring)

-online backups

what is optical storage?

data is written in a series of lands and pits on the surface of a disk, which can be read by a laser in a CD-Rom drive.

data is stored in the form of lands (flat areas on the metal surface) and pits (depressions or hollows)

lands reflect the laser light, pits scatter

what are the primary forms of optical storage?

• Compact Disk Read-Only Memory (CD-ROM)
• Write Once, Read Many (WORM )
• drives (CD-R) (R is for recordable)
• Phase-Change Rewritable (Magneto-optical)
• disks (CD-RW) (RW is rewritable)
• DVD-ROM 
• DVD-RAM

what is flash memory?

-used as a permanent storage/hard disk drive

-its very fast

-solid state storage that relies on integrate circuits to hold data (most are nonvolatile)

what does solid state mean?

what is the average access time of a device?

amount of time it takes the device to position its read or read/write heads over any spot on the medium

NORMAL -> permit you to edit/add to your presentation

SLIDE SORTER -> all slides displayed on the screen for rearranging or slide transitions

SLIDE SHOW -> show it to the public

• 
  
• 
  
• -select you slide
• -background styles 
• -format background 
• -select fill and file
• -find your picture file and use it

-insert tab, sound and movie area

-create a web version of the powerpoint presentation

-file, save as, web page (htm) -> if it doesn't fit on your disk just move it to the web folder c:\temp\web -> save as web page there

-open web page in int. expl.

-add navigational option to your presentation 

-first create the arrow by going to insert tab, shaps and action buttons

-go to your slide and the cursor turns to a +, click and drag, the arrow appears

-click on the arrow obj., right click and select action settings

-select one of the options, next slide, click ok

Dir

Delete

Run

Copy

w/ Unix (Linux) -> ls, cd, rm, mkdir

what is OLE?

object linking and embedding

Multitasking Vs Single tasking

-info. slide

single tasking = several tasks alternate using the CPU printing, word processing, downloading from internet, e-mail, etc

multitasking = much more than multiple programs loading into memory. Means being able to perform 2 + procedures (printing a multi-page document, send an e-mail)

what is time sharing?

a technique that enables multiple programs to share processing on a rotating basis, similar to multitasking. A time-sharing computer spends a fixed amount of time on each program and then goes on to the next.

-> commonly used to allow a single computer system to support numerous users at separate work stations

what is multiprocessing?

what is parallel processing?

360K

and

1.2 MB

720 K

and

2.8 MB

• fixed and removable
• fast
• normally store software packages( music, vid)
• curently 100GB-2TB

-All high-capacity floppy disks require a drive made especially for their use

-These disks store data in quantities of 100 MB and 250 MB

-example: Iomega Zip system

there was nothing written for super disk (p.s. i just wrote dicks, hahah wow)

artifical intellegence

program or machine that can solve problems or recognize patterns

1. problem solving
2. pattern recognition

-backup copies of your hard disk needed only if your hard drive malfunctions

-b.c. the tape is a long strip of magnetic material, the tape drive has to write data to it sequentially-one byte after another

-sequential access is inherently slower than the direct access on disks

• Knowing capabilities/ limitations of computers
• informed purchasing decisions
• know advantages of future technology
• ethical legal and social implications

What must one know about a computers capabilities/ limitations

• How to avoid hackers, viruses, protect privacy and maintain upgrades

- compact disk, read-only memory

-most common type of optical storage medium

-stores ~650MB, can't be altered

-slower than hard drive

• helps you with career
• work effectively
• Ethical problems, form educated opinions

-> compact disks - recordable

-CD-R drive can write on CD

-used for storage

-compact disks - rewrittable

computer system that uses database of knowldege to draw conclusions

knowedlge is databse of "if-then" conclusions

ie, diagnosing disease

1. data input
2. data process
3. data output
4. data storage

what is CD-RW?

-can write and overwrite data onto compact disks

-a CD-RW drive can leverage high storage capacity of compact disk but revise the data on them in the same manner as a floppy

-CD use one side of disk only

artfical life

have abiltiy to reproduce

ie vrisus

what is DVD-ROM?

-digital versatile disk

-DVD use both side of the disk

-once called digital video disk

-transfers data faster

-videos/movies are stored on them

-require DVD drive (will read CD's)

like evolution,

where only the best are selected and continue to evolve

front: zip drive, usb drive, DVD player, CD ROM drive

Back: usb, serial ports

Inside: ROM and electric components

-phase-change technology used

-coated with special metal alloy compound (2 diff. appearances)

-one temp. surface reflects, higher temp its not

-before data written to disk, must be reflective

-to record onto disk, pits are burned in surface to make un-reflective areas

-erase disk = appropriate temp. used to change areas to be erased back to original reflective state

virtual reality

we know what that is.

becuase we are smart

and we see it in movies.

1. Social injustice
2. Intelectual property
3. Privacy
4. E-commerce
5. Electronic communications
6. computer abuse

radio frequencey identifier

automatic identifcation methodrelying on storing and remotely retrieving data using decides called RFID tags or transponders

-FMD-ROM = fluorescent multi-layer disk-ROM

-used special fluorescent material in reflective surface of disk

-can contain 10+ data layers (compared to 2 layers in highest-capacity DVD-ROM)

-store ~140 GB of data

-can read standard CD/DVD-ROM disk

-uses lasers to store data on the internal structure of a crystalline or synthetic cube

-could store 1TB(what the fuck is someone going to do with that much space, like seriously) of data in a crystal the size of a fucking sugar cube, whoppty fucking do

-development has been slow, haha

• used for basic tasks at home and at school
• write emails, budget and photos

FUTURE SOFTWARE OF THE FUTURE

name a bunch cuz chances are he'll quizz us on this

antispam software that works

software licnesing

creating good application programs

graphical user interfaces like voice and hand and visal recongition

group computing

data minning/ data warehouses

object oriented programing

affective computing

=D

helps run the computer instructions between application software and hardware

• consists of operating system + utility programs

-contain a sm. chip that stores data

-need special device to read, add/edit data on them

-intelligent smart cards also contain a tiny microprocessor chip and their function like a comp.

-example: hotel key cards and credit card inside the hotel will be used to store digital cash and medical history of you (creepy?)

preform general housekeeping tasks

ie. system maintainence and file compression

name language and dateand sample statment with gen

first gen

second gen

third gen

forth gen

beyond forth gen

first gen - machine language- 1940-00100

second- assembly language- 1950- MVC

third- highlevel language- 1960- READ SALE

fourth- query and databse language- 1970- print employee number

BEYONDDD- natural and intelligent- 1980s- "if-then"

-designed to run on a network SERVER dedicated to providing various service to other comps on the network (EX: windows 2003 server, Linux for servers)

windows

mac

unix

-operating system that is built into an electronic device (stored on ROM)

-for PDA, appliances, cell phones, etc

-smaller version of operating systems required for these products (ex: windows XP embedded, like real world XP operating systems)

graphical user interface (GUI) displays graphics wit point and click technology 

enables interactions with computer

Do u know ur hacker methods o.0

if yes, define:

denial of service

trojan horse

time bomb

logic bomb

denail of service- sends thousands of messages to same site, and tie it up

trojan horse- looks like its doing one thing, but its actully raping u in the ass

time bomb- unnoticed till triggerd. ie HAPPY BDAY on ur bday

logic bomb- triggered by apperace or dissparance of data

UNIX (1970) -> LINUX (1997-9)

info-fucking-mational slide, bitches and hoes

UNIX - could run on a single comp, or a network

-preemptive multi-tasking 

-allows for multiple users, from more then one monitor/keyboard

-supports a multiprocessor systems ->a PC with more then one CPU working at a time

-runs on many types of computers, includes: supercomputers/notebook PCs/everything between

-because it can work with so many kinds of hardware it became backbone for internet

-runs on micro to super computers

-manufacturer independent

-GUI called x-windows (not great)

1. output input system activated by powering CPU
2. checks that all devices are in place
3. OS in loaded in to ram
4. configuration and customization settings are checked

-more difficult to learn

-limited business applications

-hackers -> network attacks

-this is the newer version of UNIX

-full 32-bit, multi-tasking operating system that supports multiple processors

-can run on nearly any comp, support almost any type of application

-driven by command-line interface

-it was created by ppl who believed we should have free operating systems

access to computers main files and folders and common tools applcations

and applications running on the system
