The different external components are:
They are used to input information: keyboard (text input), scanner or camera (image input), microphone (sound input).
Due to the lack of direct vocal encoding, the keyboard is THE input device for text.
The best of the keyboards: 10 years of hard working
before death ;-)
The worst ADB Apple has never produced: awfull key rendering, noisy, ADB connector on the rear... :-(
USB keyboard of the early iMacs: connectors on left and right... back to user friendly design :-)
The transparent PRO one: big function keys... but very quickly dirty.
A Macally keyboard. Very good.
And now, one can find wireless keyboards or one can use USB PC keyboards.
From left to right: a MacPlus mouse, one of the last Aplle ADB mouse, the first Apple USB mouse and the Apple basic optical mouse.
If you have to change your mouse, I would suggest the
optical choice... but not the Apple one.
... here it is.
One can alos find wireless mouses. Either optical one
(infrared) or Bluetooth based (radio frequency).
A USB trackball.
A USB graphic tablet. Many people who has one does not use the pen... and are happy: (1) not have a wire to the mouse and (2) not be forced to use batteries!
This peripheral is used to scan a image lied down on a
glass and memorises it in the computer.
In the past, they had a SCSI connector. Now they use USB or Firewire.
Several points can help to select a scanner to buy:
Such devices help you to enter images/fims or sound form
several sources (TV, camera, ..) into the computer.
They allow to extract information from the computer and send it on the screen, on a printer, on a fax, on a modem or a network.
At the very beginning, Apple use a proprietray DB 15 connector system which forces mac lovers to pay expensive prices for display monitors. For instance, in '91, a 13'' display monitor cost 800 euros. i.e. the actual price of a low end eMac !
Then next, Steve starts to think... -> the VGA connector, the same as the Empire has, is used on Mac. More, the DVI one is also used: this Digital Video Interface transmits numerical signal and not analogic one!
Then, Apple comes back to its bad "proprietray" pratices:
the ADC strikes back -> so to connect a modern display
monitor to a (?modern?) Mac, we have to insert a DVI ->
ADC adapter (150 euros).
-> So, before using a new monitor, check the connectors!
Fortunately, on modern Apple monitors, standard DVI
Printers were first connected through a serial cable (mini-din 8) or through a LocalTalk network. With iMacs, arrives the USB standard...while the ethernet was still wisdzly used;-). Once upon a time, on Mac machines, one cwas able to use infrared connection to print, but now this type of connection has disappeared: Bluetooth connection is the "up-to-date" fashion.
We have inkjet or laser printers:
In the past, they were external devices, connected on the serial port and expensives (let's say, 8 years ago, 250 euros for a 14.400 bauds modem... 4 times slower than the standard RTC modem you can fine in iMacs). Now, all of the modems are connected to the USB: either they are really USB ones, either they need a USB to serial adapter.
To send a fax, you need a modem but also a standard phone line: fax cannot be sent through a DSL or cable modem!
Always, the Mac was a communicating machine. First we have AppleTalk protocol in a localtalk network: easy but not quick, one can share files or printers.
Then come network cards, first in BNV with coaxial
Then the base-10 RJ-45 , followed by the base-100 and
Now, we have wireless networks: with airport 802.11b (11 Mbps in theory..6 in pratice !) and airport extreme 802.11g (54 Mbps in theory... 30 in reality !). They are based on radio frequencies in the range of the 2.4 GHz. Machines in a radius of 300 meters can be connected to the same station.
There is also the Bluetooth system (1 Mbps in theory) but not so far network minded: more for cellular phones, peripherals (printers,..), ...
And now Apple is focusing its attention onto FW-based networks.
To store data for backup, exchange data from one machine to another or simply to have an extra capacity.
Short description. There are 3 types of external hard disks:
SCSI: very expensive.
Note that, in general, USB & FW external drives are not totally USB & FW but contain a EIDE-> USB/FW internal bridge !
4 types of external disks: from top to bottom: an 2.5'' in a FW box, a 3.5 '' EIDE in a FW/USB1 box, an SSCI one in a powered box and finally anothe SCSI disk.
Face view. About capacity:
The most commonly used removable storage devices (tapes drives, less used for domestical purposes, are not shown):
The only removable storage devices which has survived is the ZIP... despite all its weaknesses.
Compact Flash USB reader (with a 64 Mb card). That's the tendency of the moment: FLASH memories within keys, cards,... 32/64/428/256/512 M are common; 1 G are still expensive.
I would prefer the card+reader choice: less expensive, reader is faster, you can use the card directly in modern PCs or laptops... not in Macs!
No mechanics inside -> more resistant, less cumbersome... but more expensive.
The most widely used storage support is the CD-R. 700 Mb on it, quick to burn (modern burners run at 52 X) and all the actual machines have one.
-> the solution for transfering data (files, music, games,... ).
Bigger is the DVD (4,7 gigas). Unfortunately, the big
problem of the DVDs is the disparity of their formats.
Modern burners are now of the USB2 and FW types.
In the past, they were SCSI: 500 euros for a 4X CD-R
burner. Yes. Really ;-).
