 Output unit  is used to communicate the results of data processing carried out by the processing unit to the outside world. The example of output devices are:
Printer - produces a permanent human-readable text or graphic documents.

An example of audio input device is microphone, which provides input by converting sound into electric signals.

Webcam - low resolution video camera used to provide visual input that can be easily transferred over the internet

Monitor - A monitor is the screen on which words, numbers, and graphics can be seem.  The monitor is the most common output device.

Floppy Disk - A floppy disk is used to record information on.  The information is stored on the floppy disk and can be used later or used on another computer.

Compact Disk - Some compact disks can be used to put information on.  This is called burning information to a CD.
NOTE:  A CD can also be an input device.

Computer output devices deliver data that has been processed by the computer to the user. There are a variety of devices that produce data in different forms including audio, visual and hard copy. Computer output devices are types of peripheral hardware connected to a computer, using cables or over a wireless network.

As the assignments get more complex, I found myself begging for a simpler coding environment. So, this week, I made my own fabduino, so I can now use Arduino libraries. That is up and working well. I had a little problem programming it since my USB port was acting up, but after trying it on Ed Baafi’s computer, things worked great.

Manufacturer: Jobo
Model: Spectator
Price: £199

Jobo may be traditionally known for darkroom equipment, but recent years have seen its fortunes resurrected thanks to image storage.
Joining portable image viewers and hard drives such as the GigaVu, the Jobo Spectator is the latest addition to the range. This tough-looking device is rather more pedestrian in design than the curvy Giga Vu, with a small 2 inch LCD screen and card slots for CompactFlash, SD and Sony’s Memory Stick media.

 ATX motherboards usually have up to 7 expansion slots. The type of the slots depends on the chipset, some have 7 PCI-Express 16X slots, while others just one and offer more backwards compatibility for PCI. ATX motherboards are based on expansion cards, so very few have on-board graphics (as part of the chipset). The chipset consists of the two larger chips on the motherboard, covered with relatively large heat sinks. These create the interface between all components installed in slots and sockets on the motherboard. The industry is slowly moving towards integrating everything into the processor, Intel successfully included the memory controller and graphics processor on the processor while AMD integrated just the memory controller into the CPU.

 

 

 

 

 

While this specific motherboard has almost all the features of a complete computer system, it lacks the  PCI-Express 16x slot for a gaming graphics card. There are a few models out there that have exactly on PCI-Express 16x slot, but the big majority has only a PCI or PCI-Express 1X-4X (or none at all). These very small motherboards also have fewer memory slots, usually two, but there are some models with only one memory slot.
In conclusion the size of the motherboard directly influences speed and maximum memory capacity, but not the other features. Even with no expansion slots at all, most type of components (TV-Tuner, Wi-Fi/Bluetooth module, additional network card, sound card …etc) can be connected through USB ports.

Some manufacturers don’t see it as a bad thing, they managed to implement two PCI-Express 16X slots for gaming computer systems. Two such slots are enough for most gamers, because the most extra horsepower you get with the second graphics card, while the third and fourth offer far less advantages. This specific board doesn’t have IDE nor FDD controllers, just SATA. As you can see all parts of this motherboard are much closer to each other, but that’s not a bad thing as long as proper cooling is insured. When we look at benchmarks, mATX boards are just as fast as their ATX cousins, that have the same chipset of course. Please note that some chipsets are made exclusively for mATX or just for ATX motherboards.
