Computer Hardware

Floppy and CD drives are both Output and Input devices based on the context of their usage. For instance, you know that both the drives can read and write their respective media, i.e. input and output. But consider the case where you insert a pre-recorded CD or write-protected floppy into the drive, here the drive falls-back to being an input device. Classifying computer peripherals into I/O devices only is not very efficient now-a-days due to the Hybrid nature of these peripherals. So instead, classifying CD and Floppy drives as Storage Access Devices is more appropriate. The term access here has significance, since the drives itself do not store any data as opposed to common parlance, instead they simply access the Compact Disk and the Floppy Disk for the data.

One option would be to implement your applications in QNX, and use the incredibly powerful networking capability and their IPC capability.

I would like to describe remaining advantages and disadvantages briefly. Mechanical Mouse:Disadvantages * performance and tracking ability depend on the surface the mouse moves * need mouse pad or any special surface * the cursor movement looks not smoother to the end user * When you use mechanical mouse, you need to clean the dirt or debris that comes inside the mouse so that the ball and rollers are able to move freely when the mouse moves * Mechanical mouse are heavy generally. Advantage * Low cost Optical Mouse:Disadvantages * Much expensive than Mechanical mouse * Mouse code is required. Physically should be connected to the computer Advantages * Optical mice usually function trouble-free for years * Early optical mice required a special mouse pad, but today's devices can be rolled over traditional pads like a mechanical mouse as well as over almost any surface other than glass or mirror * precision of optical mice is also much greater than mechanical mice * There are no moving parts to break or otherwise cause problems * Weightless Wireless MouseDisadvantage * Much expensive * battery required for some designs Advantage * Cordless mice are more and more popular because they can be used without physically being connected to the computer, which gives a sensation of freedom. * free up desk space and elimination of mouse cord * not need special surface

Network Interface Cards

It's called plug and pluy (PnP).

Touchscreen. You see them every day on kiosks, cell phones, and PDA devices. The output is what you can see on the screen. The input is when you can control the device by touching images on the screen.

Cable networks use coaxial cables to connect computers to the internet. Their advantages include fast internet connection of up to 15 mbps, not prone to dropout as compared to dial-up internet and ability to support data-heavy online activities. High installation fees, slower speeds than those of fiber optic networks and inaccessibility in other areas fall under the list of disadvantages.

yes i have this laptop and it comes with a built in microphone as well

Personal System 2 (IBM PC and a connector format)

The RAM (Rapid Access Memory) sticks you find on the motherboard store information on running programs to access those programs, or things in those programs quicker. The RAM is automatically cleared once the computer is shut down or restarted. If you look at your motherboard, the RAM sticks will be found usually between the CPU (Usually not mistaken by the fan mounted on it, and just under the power supply box) and the hard drive/CDROM drive, or other devices found in the front slots, and are facing you perpendicular to the motherboard. They can be removed, replaced, and more RAM memory can be purchased in new RAM sticks with more memory built into them.

Also, the computer stores other memory for the RAM to access from the Hard Drive. This is called the Page File. The page file can be deleted or not upon shut down. It just depends on what your computer's setting is set to regarding that.

Generally somewhere on the motherboard.

The electronics inside of the power supply will overheat and cause the power supply to quit working. There might even be a small fire inside, or the semiconductors may crack or explode. So it is best to repair or replace the power supply when the fan starts to malfunction, since it will be easier to fix. If you must operate it that way, you should take steps to reduce power consumption and make sure the fan is running each time. Some even insert things in there to start the fan if it is stalled, though that has its risks.

IDE: An older 'ribbon cable' parralel communication technology. It capped out at 133 MB/s transfer, and could have 2 devices plugged into 1 port (Master and Slave) sharing the same channel. Also known as EIDE (Enhanced IDE), ATA, and PATA (parralel ATA)

SATA: Serial version of ATA (hence SATA) which comes in I, II, and III varieties, which operate at 1.5gbit, 3.0gbit, and 6.0gbit respectively (187.5MB/s, 375MB/s, and 750MB/s respectively). It supports Native Command Queing (NCQ), hotswap, and a few other features. It is noteably lower latency than IDE (quicker response time) and lower power. It's also cheaper and easier to plug in, using a smaller cable.

SCSI: Small Computer Serial Interface (sometimes Small Cheap Serial Interface or similar) is a type of serial communication that predated SATA, and came out alongside IDE. It is now largely used only in servers, and not personal computers. It is an expensive interface (which is ironic for the name) and can provide speeds exceeding IDE and most SATA. Some versions such as SAS (Serially Attached SCSI) and FibreChannel use very high-speed and fiber optic links to acheive maximum speed. However, harddrives rarely exceed 150MB/s even in the world's fastest, 15,000 RPM harddrives. So such interfaces are rarely useful for single-drive soluitions.

The advantage of SCSI is that is has (arguably) superior RAID support, allowing multiple drives to act as one, and combine their power, or to mirror each other for data redundancy backup. It can also be 'daisy chained', connecting one drive ontop of another in a chain to a single port, thus allowing many drives with less individual cables and easier management and organization.

'No modem present' generally means an error with the connection to the internet.

The Modem is the middle component between the router and the internet, it recieves data from a jack that allows internet access, which is passed through the modem to the router so that wireless enabled devices can access internet.

A computer can connect directly to the modem in order to gain internet access and a router is optional not compulsory.. Without a modem, you cannot recieve internet access.

And exactly what is "at" that you are referring to.

When referring to an Edit Suite or Software package, the hardware limiting factors vary greatly and depend on the exact software.

The shinier one.

Dial-Up Internet: A dial-up Internet connection is the most basic and therefore the slowest type of Internet connection that you can get. Connection rates for dial-up modems tend to fall between 2,400 bps & 56,000 bps, which is incredibly slow for today's high speed Internet and applications. Dial-up modems are attached internally or externally to a given computer, and then connected using a standard telephone cable. All in all, dial-up Internet connections are outdated and representative of an older and more basic Internet. ISDN: ISDN (Integrated Services Digital Network) Internet connections are a type of digital telephone connection. ISDN connections straddle the line between basic narrowband Internet connections and more advanced broadband Internet connections due to the fact that Basic Rate Interface (BRI) ISDN connections transmit data right around the broadband cutoff at 100 Kbps. Although a better Internet connection option than dial-up, ISDN connections are still more or less outdated. Digital Cable Broadband: Cable broadband Internet connections are the most common type of broadband service. Connecting to the Internet via your cable television signal, cable broadband Internet connections offer data transfer rates of approximately 1.5 Mbps, far exceeding those offered by either dial-up or ISDN connection types. DSL: Digital Subscriber Line Internet connections are the second most common type of broadband service offering data transfer speeds similar to those of cable broadband (_1.5 Mbps). DSL services connect to the Internet via copper telephone wires. The difference between DSL and dial-up / ISDN is that a DSL Internet connection uses a high speed dedicated circuit filtering out standard phone calls and Internet signals. WI-FI: Wireless Fidelity Internet Connections are currently the hot commodity in high speed connectivity. They boast similar transfer speeds as digital cable and DSL broadband, but they don't require any type of physical connection in order to transmit/receive a signal. T-Carrier Broadband: T-Carrier Internet connections are some of the fastest available in the world and are generally reserved for use by large businesses and universities. T1 and T3 Internet connections are the most common T-Carrier types, and can cost as much as $800 and $15,000 per month respectively. T-1 lines boast speeds of 1.54 Mbps whilst T3 lines boast astounding speeds of around 45 Mbps. OC24: An OC24 (Optical Carrier level 24) Internet connection is a fiber optic connection capable of transferring data at a mind-boggling rate of 1.244 Gbps. This is pretty much the fastest Internet connection that you can get and generally serves as the backbone of various NAPS (Network Access Points).

Some would say yes, and they may be right, but i cant tell the difference on my 21 inch screens.

ATA-33/66/100/133 are speeds at witch the hard drives pass information to each other and other drives CD/zip/ect. 33 denotes a speed of 33 megabytes per second max transfer rate. 66 Mbps and so on. The motherbroad will see both. but may not be able to transfer data at the speeds rated by the drives http://support.intel.com/support/motherboards/desktop/se440bx2/sb/cs-013633.htm When in doubt ASK INTEL. True they don't support everything indefinetly (sp) but they DO SUPPORT THIS BOARD... Answer = "Hell NO!" Below is an excerpt from the page link offerd here. Will my ATA-66 hard drive work on the Intel SE440BX-2 Motherboard? The IDE controller integrated into the Intel SE440BX-2 Motherboard supports Ultra DMA modes 0,1, and 2. Ultra DMA mode 2, also known as ATA-33 or Ultra DMA 33, is the highest transfer mode supported by the Intel SE440BX-2 Motherboard. The motherboard hardware cannot support the maximum transfer rate of the ATA-66 drives. ATA66 hard drives will only operate up to ATA-33 on the Intel SE440BX-2 Motherboard. Please refer to the Technical Product Specification and the Motherboard Specification Update for more complete details on the various transfer modes. I had to look it up myself as I upgraded this very board with a better chip. Bloody thing will run a 550MHz processor and can't pass ATA33

It is possible for a 80486 based computer to access and manage audio and video files, playback of those files is a different matter. Audio files like mp3's and .wav files will play without problems, but there are very few (if any) video codecs which will play reliably on hardware that slow.

Anything 66 mhz or faster should be able to play most mp3's.
Video playback generally requires at least 300 mhz.

No. When you update the USB Host, it updates all the 'ports'. Actually, the physical ports are just places to plug things in. The updating actually happens with the software hardcoded into the USB Root Hub, which controls all the ports.

It would depend upon what you're making a podcast for.

If you spend lots of time on your podcast and use lots of effort, you'll do great.

An example of a good podcast is: Film Flim Flam at filmflimflam.webs.com. Make sure you check it out for some good pointers. (Did anyone notice that is a Freewebs website.?)

Yes.
