Talk:Peripheral
From Wikipedia, the free encyclopedia
I am wondering if this article should be merged with the article "Peripheral device". They seem to mean pretty much the same thing, but the Periphery disambiguation page states that a peripheral is not to be confused with a peripheral device without giving an explanation why. The redirect page for Computer peripheral links here.
Also, Peripheral device and peripheral have a different set of other language links. I linked the Dutch version (nl:randapparaat) to this article, but I did that before I discovered the peripheral device article so I'm wondering if I should have linked to the peripheral device article instead.
- Yes, the two pages should be merged. There are three ways of thinking of peripherals, the "peripheral device" article, my way (the right way of course :), and the "peripheral" article. 1) "in the old days" The veiw of the computer hardware designer, anything but the CPU. 2) Anything that does not attach directly to the main system bus. The motherboard, and all the chips on the motherboard, and anything that plugs directly into a PCI slot are _not_ peripherals, although the CPU designer thinks of them that way. Disk drives, CD drives, DVD drives, keyboards, monitors, mice, and so forth _are_ peripherals. 3) Anything that you don't get with a cheapo computer purchased at Best Buy is a peripheral, what comes in the package you buy is not.
- To my mind 3 is a pretty meaningless definition, even to today's casual computer user.
- In the future there will be confusion as to whether network attached devices are peripherals, things like network attached disk drives that you can share throughout your home network.
- The question to answer regards peripherials is "What does it plug into?" Peripheral to what? 1) says it plugs into the CPU. It must be very close to the CPU. It gets power from the same wires the CPU does. 2) says it plugs into the motherboard (or backplane etc.) or an attached circut board. It must be pretty close to the CPU, attached to a single run of cable, perhaps with power boosters to extend the cable range. (Think USB hubs.) Power comes from different wires than that which powers the CPU. (Maybe not always, but I bet in a good design the keyboard and mouse don't share power with the CPU so that when you drop your mouse in the coffee you don't fry your whole computer.) 3) says nothing. And then there's network attached devices, another sort of peripheral. These may be anywhere on the planet or off it, and traffic to them may be routed, that is travel via multiple paths. The routing is the distinction between things like USB peripherals, bluetooth devices, or even (to my knowledge) fiber channel attached devices, and network peripherals. (There might be an intermediate catagory of storage area network devices in there somewhere, but these seem to me like a long complicated scsi bus -- without (usually) the simultainous sharing and certainly without the routing that you can have in network attached storage.) --kop 20:11, 23 July 2005 (UTC)
- So, there's peripherals that plug into the cpu, peripherals that plug into buses and connectors other than the main CPU bus, and peripherals that plug into the network.
- I don't want to lump the main system bus in with other buses, not because other buses (like USB) are external to the case, but because things that plug into the main system bus are effectivly plugged into the CPU. That's the point. They are peripherals in sense 1 -- things that plug into the CPU. (Keyboards and mice BTW, and for that matter things like IDE drives, may plug directly into the motherboard but there's mediating electronics between them and the CPU.) --kop 20:30, 23 July 2005 (UTC)
[edit] Renaming
Peripheral (this article) should be renamed to Computer peripheral. Also, I have proposed to rename Category: Computer device to Category: Computer peripherals (see Wikipedia:Categories_for_deletion/Log/2005_December_19#Category:Computer_device_to_Category:Computer_peripherals).

Actually I suggests not Cateogrized it or renaming it. The name you give for renaming is incorrect for IT terms. Also peripherials is one of the most commmonly confused term in PC terms, so I guess it should be Computer Device or put it like so: [[Category: Computer Device [Peripherials]]] 23:39, 26 May 2008 (UTC)
Sorry I wrote a bit too much
-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
I propose on deleting the "Peripherial Device," because that articles is almost exactly same as Perpherial in terms of content. The only thing that can be added is possibly the specifications of internal peripherial & external peripherial specifications and portfolio such as ATAPI.
I really doubt, NAS, SAS & Fiber Channel would ever be confused with peripherial, they are only an interface or most technically an architectural system interface for a server. Generally speaking most enterprise buisness consdier them as "Architectural options for SANs."
I don't think you should put the part that you said about "What does it plug into it," because strictly speaking all internal components of motherboard that is irreplaceable by technology uses power from their own internace (CPU, RAM, Graphic Card would almost 98% be limited to their design, no matter how powerful technology is, the only thing you can change is their Gate arrays and nanoarchitectural design for better transfering speeds and the nanotechnology, but no matter what CPU is still limited to the various amount of PLD packaginig avaliable).
While Components that is possibly replaceable by technology, uses power from PSU, such as Hard Drive, because HDD can have multiple interface options, so it wouldn't be too much hassle to reconfigure BIOS all the time, just for power.
PCI Express Graphic Card connnector is an exception and you can't argue about that, because the inital design wasn't intended for easy installation, it was intended for enthusiast.
Transfering power for external I/O are considered more of personal options that is why they are design to plug onto the motherboard in most cases, while portable / mobile external I/O uses port for easier transportation.
I know a lot of you guys might argue that Graphic Card, isn't an essential components, but actually it is consider to be added as one of essential components, since the current CPU-can't be regarded as a true-CPU, because it can't handle a lot of process inefficiently, due to architecture design flaw (see bottom paragraph for summary). One of the reason, is that current CPU design can't handle management efficiently like jsp, cfml applicatons and other object-related operations very well. This research actually lead to a serious of discovery on Microsoft window OS, because much of the Windows OS enviroments is design for Intel. A simple example, is the design flaw in RAM memory protected mode, that causes Buffer Overflow. (If you want to know more, go edit my User Page for questions) see CPU dicussion on CPU Architecture for details and you'll understand why.
CPU in brief In short CPU, the central = management, however, the design today are efficient (because, when you are doing things like abstraction you get 80% ALU, 15%NPU & 5% FPU) usgage, unbalancing management and causes unncessary overheating up to 40~50 degree Celsius is definately not "management" as describe in CPU expectation. Another flaw is CPU rescheduling, since components are already almost at full you can't rescheudle anything, because the more you add the probability of crashing increases. Thus the only true-CPU is MAJC, because the entire components can process anything, thus rescheduling wouldn't be a problem, because each transitor is only using partial usage (also their process in being evenly balanced across each transistor, thus it won't cause overheating and achieveing management).
The reason why MAJC isn't recognized as true-CPU yet, because processors are usually very dependant on chipset technologies stability, but Sun Microsystems (designer of MAJC) hasn't come up that technology. You can see that processor is very dependant on technologies, because Intel Dual Core + Chipset (has a lot of technology, such as speedstep, flex memory access..etc.) While AMD Athlon Dual Core has almost nothing.
Note: the scale / dimension of the components, mostly affect the heat being produced, usually doesn' affect speed, because small volume = larger surface area, but CPU doesn't uses surface area, since they aren't life therefore they don't require to interact any other components, other than the components that they are intended for(in this case is the DDR2, HyperTransport and FSB). --Ramu50 (talk) 17:42, 1 June 2008 (UTC)
[edit] Monitors?
I would like to draw the attention that the definition disagrees with the webopedia definition. Monitors are peripherals. Computers are able to function without the need of a monitor even though u would not be able to view the output :-) ! Maltesedog 12:32, 31 May 2006 (UTC)
[edit] CD/DVD/etc...
Aren't CDs and such storage not peripherals, but rather the individual CD DRIVE? technically aren't the CDs and DVDs used IN/WITH the peripheral? --FranzSS 03:04, 24 August 2007 (UTC)
