7. laser printer and other non-impact printers print much faster than impact printers. the print is also clearer. the other ones are noisy and are best for printing documents with just charters on them. also ink jet printers are non-impact and spray the paint as opposed to the impact printers which prints out a series of lines.
8. Storage devices can work as both an input and output devise. For example tape drives, they can write data onto and read data off of a magnetic strip on the tape. these devises are also called secondary devises, a primary device is a ROM.
9. sequential access memory can only access the memory in the order in which it was recorded. it can retrieve information in the middle of the recording without going thru the whole tape. while the RAM can. the RAM is used in everyday computing while we use sequential memory is used for backing up data or other operations that aren't time consuming.

HW DEC 23
http://www.questia.com/read/5021318097?title=It%27s%20the%20Little%20Things%3a%20Cutting-Edge%20Computing%20Accessories%20Improve%20Productivity%2c%20Enhance%20Security%2c%20and%20Refine%20Systems%2c%20Putting%20So-Called%20%27Peripheral%27%20Needs%20Front%20and%20Center
Reading Review DEcember 23
- List five input devices and three output devices that might be attached to a PC. Describe a typical use for each:
input:
Mouse:commands and positions the cursor. it also allows for the user to select applications and basically everything on the computer.
key Bord: enters text and numeric data into the computer and projects it on the screen.
joy stick: used in gaming, the joystick controls the cursor. It is a gear shift device.
track ball: similar to a mouse, but the mouse part stays stationary while you move a ball in the center.
Touch screen: it responds to touch, your finger works as a pointer, rather than a mouse. used in PDAs and places like library and Airports.
Output:
Printer: the printer outputs information on the form of paper. its very nifty.
speakers: speakers let out sound files that are on the PC
Monitor: we SEE things from the PC by the monitor.
- Name and describe three special-purpose input devices people commonly use in public places, such as stores, banks, and libraries.
-touch screens: used in libraries airports as directories and in stores for self check out
-Bar code readers: used in stores to scan prices, also in libraries to scare book codes
scanners: used in banks to fax or copy important documents
- Many people find that the mouse is impractical for use as a pointing device on a laptop computer. Describe at least three alternatives that are more appropriate.
-touch pad: these are Usually attached to a Laptop anyway. its more practical for a devise on the go.
touch screen: this will work nicely you can just touch the application that you want on the computer.
graphic tablet: the computer will then be like a notebook which is more practical than a mouse.

CRITERION G!
criterion G: Identifying a problem within a Social Context
the problem here is that There are many talents that are hidden becuse it is not properly displayed. Some talents include Poetry and art. Fadehlah Fattouh a senior at Alarqam has amazing artistic talents and poetic abilities. Socseity will benifit from her peoms, they have deep and wonderful messages that anyone can realte to. the problem of the current, is that only her immeidate family and firends see her talaent, its not dispalyed anywhere. if i were to make her art known, then she can benefit and maybe get some publicity and attention.
Criterion H: Analysis and Feasibility study
the IT Solution here would be to diplay her art on either a blog,web page, or web gallery or video blog. the most efficient and professional would be the web page/gallery, its display is cleaner and more precise than that of a blog. A video blog would probably be of just recitation of poetry, which would be nice but not to the effect of a online gallery. if i were to display these items on the internet, she may give people the URL and her poetry and art will be more known, also people from all around the world would be able to see her poetry if they searched.

1- is there a significant difference between a pair of glasses and an artificial retina, or between an artificial hip and a lower-extremity exoskeleton?
no there both have always been there in theory for a long time. its always been there but now its is becoming "more organic" by merging it into the body.
2- what are the potential benefits and risks of advanced bionic devices containing embedded microprocessors?
there are many benefits, like help people that have lost their sight, or for people that have lost their hand etc, also in can better human life like make us stronger, or carry heavier things, like the firefighter who can carry a heavier load to save more people etc. it can be a bad thing, of course, if its used in the wrong ways, in violence, and in hate. also it can make us dependant of these sources of strength.
3- if advanced bionic devices are conceivable do you think their development is inevitable?
i think now that its actually possible to create types of machinery, then fore SURE it will be invented, i wont be surprised that in the next couple decades, people will be switching their legs for robotic legs....maybe not that extreme but it will be used!

review Questions page 60
Review Questions:
3) we write it as "123.4" but when the computer sees it they see it as a set of 1's and 0's. this Differs from the usual train of thought, even though we think it seems easier for it to be read as 1234 the computer finds it easier at 10001 or something.
4) because computers can only read the number 1,0. so any other number letter etc cannot be read. this binary system allows to the computer to read the information.
5) because PCs and APPLE computers are built differently, therefore cannot read the same soft wear like the Intel Pentium 4 CPU.
6) it can also be limited by the Architecture of the processor, the design can limit this by the location it has on the chip.
7) internal expansion is used within the computer and external expansion is used when you plug things with information into the computer like a USB or memory chip. wit exanation cards users can customize their computers.
8) multiprocessing is putting multiple CPUs in a single chip. and it speeds up computer, therefore enhancing its performance.
9) RAM-Random Access memery and ROM-Ready only memory. ram is used with temepery files and information is added to it, but when the computer turns off it doesn't save. ROM is set and has information on it, but the computer can only read it and cant add onto it.
10)primary storges are like RAM and ROM and the computers memory. 2ndary storage are storage devices like CDs and hard drives.

Answer the questions December 8
What are the four basic functions of a computer?
-receive input, process information, produce output, store information
What does CPU stand for?
-Central processing unit
Explain what a bit is.
- a bit (binary digit) is the smallest unit of info and computer can read.
Name two codes used to convert words, etc. into bits.
-one code is known as the ASCII (American Standard Code for information interchange)
-Unicode this one is used to compute different languages as well.
Why is information's stored in some kind of binary format in computers?
-because computers cant understand numbers pictures and words, the computer cant process info without dividing it into smaller units which are known as bits.
-receive input, process information, produce output, store information

the inside of a computer: Notes
YouTube computer Tour:
*7 major components
1)mother bored- every part connects to it
2)CPU (central processing unit)- the brain of computer, runs the soft wear, sits under the fan
3)RAM (random access memory)- holds the data or soft were that your running (speeds it up)
4) video card- creates images that appear on monitor
5) power supply- sits on top of case and supplies the power
6) HARD disk- hold the info even when you turn it off...
7)optical drive- sits in the front it reads CD and DVDs

tech reflect: telacommuting
1- Tech Reflect: Discuss the advantages and disadvantages of telecommuting.
there are many advantages of working from home. i want to be a business owner in the future inshllah, but i also have the responsibility of manning the fort, so it would be nice to own an online business at home, or managing the business at home. that way i don't have to leave all the time, and it will also save time and effort., and not to mention gas money!
but there are many disadvantages of telecommuting, one will start to get lazy, and maybe not take their work as seriously as they would when they have to do things face to face. All working form home is very limited and you have a limited amount of clientele.
it all matters on what the profession is and if there are many outlets to it online, but i do prefer the old fashion way, and that is face to face.
also telecommuting can be a threat to security and privacy, because you don't know who is watching your online conference, or who has access to your email and info, but working online also gives equality of access because since its online anyone around the world can access it, while if it was face to face only a limited amount of people can access you.
