REECE VOAKS ( HI GUYS ) BLOG -_-

these are the steps to form a successful installation of a printer

step 1: the first step you do is plug everything in and make sure everything is working

step 2: to the manufacturers website and download the driver.

step 3: this shold allow you to install the printer safely.

step 4: press install or run and it will load and be installed

step 5: you will have to do a test print page and it should work and will be successful.

PRINTERS 

laser printers - 

A laser printer is a high-quality, fast printer that uses a laser beam to create an image this the newest kind of printer that can print up to 200 ppm were as any other printer prints 8 pps and this is how it works:The central part of the laser printer is its electrophotographic drum The drum is a metal cericle that is coated with a light sensitive material.  When a beam of laser light strikes the drum, it becomes a conductor at the point where the light hits itit creates a ink picture you would use this printer at a businessor a school these have diffrent rolls of tonesfor diffrent colours.

 inkjet printers-

Ink jet printers produce high-quality prints. Ink jet printers are easy to use and inexpensive compared to laser printers.The print quality of an ink jet printer is measured in dpi (dots per inch). Ink jet printers use plain paper to make  prints. Special-purpose paper may be used to create high-quality prints of photographs you would use this at home. 

 

dot matrix-

The first high speed printer was developed to use the Uni vac.while the first dot matrix printer was marketed by IBM, in 1957, the same year that the dye-sublimation printer entered the market. and also this old printer were worth about £300 know you see not alot these types of printers its worth about £9000 and also this printer , when it prints pages out it comes out a bit blurry and squished together as it is not rated printer.you would use these at science laboratories.

 

thermal-

 this printer is used for receits so it is a very small printer. it puts data on to the page with selective heat the coating turns black in areas were it is heated producing an image. thermal printers are capable of  printinbg both black and additional colour mostly red by applying heat at a different temperatures.you would use this printer at shops and buisness.

 

chapter 6 was about laptops and building them and taking them apart.It was good we learnt when the first laptops were made and what model they were and who made them tis is some infomation about chapter 6,

they average laptops was worth about $8,000- $10,000 and weighed about 24 lb ( 5 kg ) in 1981 there was no CD Rom’s it was all done by floppy disk until 1991.

smartphone standards:

1G: The first generation (1G) of cell phones began service in the 1980s.

2G:the second generation (2G) of cell phones was marked by a switch from analog to digital standards. Second-generation cell standards included Global System for Mobile (GSM).

3G: As 3G cell phone standards were being developed, extensions to the existing 2G standards were added. These transitional standards are known as 2.5G standards.

4G: (4G) standards have been championed by many users, in response to the availability of increased data rates. Higher data rates will allow users to download files, such as video and music, faster than what was available with standards of previous generations. 

however this cariculem was not only laptops it was smartphones aswell one of the most leading smartphones at the moment are the iphone 3G this device helps you to listen to music email and any other stuff you will need to do. this has been a very big seller in the UK today.

there was also PDA’S which is an american device that is able to use the internet and email but its not a phonebecause it cannot ring or text its a bit like a ipod touch these used to be big and chunky but have become thinner as technology has moved on and components have got much smaller this makes it easyer o carry around and listen to music.

iPhones and DA’S are becoming much cheaper these days because of there reduced costs lighter weights and increased capabilities and hold there power for portability.

PDAS and smart phones are small handheld devices with many of the capabilities of a computer, such as an adress book, calendar,and Internet access.

laptops and desktops have ports have ports that are virtilly the same therefore, the peripherals are changeable. Laptops can use docking stations or port replicators to quickly connect to desktop peripherals and AC power.  

Desktop and laptop components, such as motherboards, are not interchangeable. Additionally, laptop components tend to be proprietary to each manufacturer and designed with unique form factors.

The laptop CPU is designed to use less power and create less heat than the desktop computer. It uses CPU throttling to reduce power consumption and heat.

 

Functionality of the laptop can be expanded by adding components via PC Card or ExpressCard slots and USB, FireWire, or parallel ports.a base station is a device that attaches to AC power and to desktop peripherals.when you plug the laptops into the base station, you have convenient access to power and the attached peripherals. 

The docking station is good for if you work in an office or computerised jobs because it charges and keeps the laptop in one place instead of it keep moving.The back of the docking station contains ports and connectors used to attach to desktop peripherals such as a mouse, a monitor, or a printer. A vent is also necessary to expel hot air from the docking station. Click the 15 highlighted areas in Figure 2 for more information about the components located on the back of the docking station:

Exhaust vent

AC power connector

PC Card/ExpressCard slot

VGA port

DVI port

Line In connector

Headphone connector

USB port

Mouse port

Keyboard port

External-diskette-drive connector

Parallel port

Serial port

Modem port

Ethernet port.                         watch?v=kq_zLXq7ElQ top 10 smartphones in 2009

SMARTPHONE: this type of phone is very clever as they are as well portable and easy to use. the smartphone  have hardley have any componenets in side them but they produce alot of heat caused from circulation they have hardley got any circulation. for example iphone and google phone, the iphone is one of the best smartphones out, they have there own internet and they are touch screen and i think that they get there name from smart because of touchscreen. the cost of a smartphone is about £100 to £600 today .

SO- the computer is on and the cpu is running

S1-the computer is not runnig however the cpu and ram are still recieving power

S2- the cpu  is off but the ram is refreshed. the system is in a lower mode than s1

S3-the cpu is off and the ram is set to a slow refresh rate . this mode is often called save to ram in windows xp this state is known as the standby mode

S4-the cpu and ram are off. the content of ram have been saved to a temporary file on the hard disk. this mode is also called dsaved to disk in windows xp this state is known as the hibernate mode

S5-the computer is off and nothing has been saved.

With laptop components they are portable and easy to take out. but with desktop componenets they are difficult to take out and to replace.Desktops you can use the common portable devices like USB’S, mouse and keyboards but they are not fully portable because you cant take the mother board or computer on the laptop is much smaller than the desktop motherboard because the laptops components have to be more compact and also the laptops motherboard is proprietary. the desktop motherboard  has at, LFX , you can also see what the motherboard holds and compare to the laptop it i think it is a lot of diffrance the expansion slot on the laptop is mini-pci and the desktop is pci , pcie , isa , agp what is alot of difference to each other.
