How is it used in a computer: The device plugs into the computer, usually by USB, and takes an image of the information under the lid. The image is sent to the computer for the user to trip up. Why it is necessary: This device is not necessary but can be useful to have adept at work or at home, to preserving and duplicating information. Scanners can also be useful when a part of pri nters or fax machines.

This means that the computer can be by past. If the user wanted to trust the information rather than make a copy of it. immortalise pickup armsWhat is it: A put down Cartridge is information stored on a magnetic mag tape for example a video tape, cassette tape and floppy disks are examples of tape cartridges. This technology is out dated but some state still use them as they had a better quality and most times last longer than the technology that replaced them. What is its purpose: tape measure Cartridges hold information, to transport or to store for individual(prenominal) use. Also some types of tape cartridges have very pocketable and limited memory they can still be useful for storing such things as word doc uments. How is it used in a computer: A tape cartridge needs a tape drive to read it, also known as a streamer. Tape cartridge such as a floppy disk needs a floppy disk drive to read the information. The drive attaches inside the computer and has an impertinent interface where there disk is inserted. Other tape cartridges such as video tapes (VHS) need a video record-keeper to read them, they use a television instead of a computer to see what?s on the tape. Why it is necessary: Like most other peripheral devises it is not necessary but useful to have to transport data and information to one place to another. Multimedia KitsWhat is it: Multimedia devices can be anything uniform mp3 players, portable DVD players or a computer with speakers, really anything that entertains mass.

PalmtopWhat is it: A palmtop i s a handheld computer (H/PC) little than a normal laptop computer. The first palmtop was made in 1991 by Hewlett Packard. What is its purpose: They can be useful to people who need a computer to do basic things and need to be portable, such as a sales man that moves around a lot. How is it used as a computer: They are used like a normal laptop although much smaller, they even have their own operating systems, Microsoft windows CE. Why it is necessary: It can be useful to have to take aim values and store small amounts of data on. arrangerWhat is it: A PDA is a personal digital assistant device it is a handheld computer, it is another form of a palmtop. I can be used to check emails, call and text people, surf the net, watch movies, listen to music, view pictures as well as store information. What is its purpose: A PDA replaces a phone, it is used in the same way but has many more features such as able to use the net profit and check emails. How is it used with a computer: Like a mobile phone a PDA can be synced with a computer b! y Bluetooth or a cable, so transfer information and data across from one to the other. Why it is necessary: Like a phone it should be kept at hand at all times, it can be used for many different things such as storing phone numbers to street addresses throughout the day. Bluetooth DevicesWhat is it: Bluetooth is a form of wireless data transfer from on device such as a mobile phone to another, creating a personal cranial orbit mesh or PAN for a short place of time (until the information has reached its destination). What is its purpose: Bluetooth is useful as there is no need for cables, it easily to transfer data such as songs and pictures form phone to phone when out and about. How is it used in a computer: It can also be used for internet, wirelessly connect to a modem with Bluetooth. This can be done from a computer, phone or PDA. Why it is necessary: It is a useful thing to have on a phone on a computer. There are also USB Bluetooth devices available for computer if the re is not Bluetooth built in. This is useful as it means that users that want Bluetooth do not have to alter the inside of their computer to have access to it. Fire wireWhat is it: Firewire is form of transferring date, like USD except firewire is a lot faster, used by personal uses to copy big files across from once place to another. It transfers at ?real-time? compared to mid-speeds. What is its purpose: Firewire is designed for file transfer. It can also be used for peripherals devices such as a printer, this allowed the data to be sent from the computer to printer. The printer has a faster reaction time as it receives the data quicker. How is it used in a computer: Firewire is connected to the computer with a firewire cable, it looks similar to a USB cable but with one end rounded. It can be used with portable hard drives other devices for data transfer. Why it is necessary: It is useful to use because oftentimes big(a) files take hours to copy across.
