External case and motherboard, power, etc. that make up the skeleton of the PC with only a skeletal semi-finished computer. A central processing unit (CPU), hard disks, optical drives (CD-ROM, CD-RW), etc. The remaining pt japfa santori indonesia elements of the user PC according to the application by adding to remove parts, thereby to establish economical system. Only recently, with the main feature of a cute little mini-PC concept is strong.
Currently being sold in the smallest form factor motherboards boast. Vertical / horizontal size of 17cm square is the one into the system on a PCB. To reduce the size of one slot is so limited. The DIMM memory or storage also significantly reduced for the port. Instead of a full-size ATX back panel size and availability through features like its own is sufficient. Via Mini-ITX (VIA) is proposed, since the prevalence of Intel processors while advocating create your own floating standard. Intel chips into chipman, rather than creating a comprehensive definition of the various components to come down. ITX small form factor on the market, such as interest, especially while having seized the initiative in the selection of the relevant standard OEM only limited use of the corporate market supply. ITX form factor, however, the market demand is gradually waking up to the G45 chipset motherboard package from the retail market began to supply.
Hard disk initialization (initialize) refers to operations. Manually scan the surface of the hard disk for bad sectors (bad sector) is previously displayed and the track (track) and the sector (sector) is supposed to be a lower work position to specify the format. Current commercially available hard disks are low-level formatted pt japfa santori indonesia at the factory to both HDD user is finished, so again, there are no need to be lower format. The format of the operating system is generally a high level format. (Logical)
NCQ technology control software on the hard disk platter to analyze the state of the data store down the CPU to read and write command sequence is itself changing technology. E-IDE hard disk data down the CPU read and write commands to be processed in the order received. Material pt japfa santori indonesia near the head or read it too bitter, pt japfa santori indonesia but the command does not exist, just past the throw, not the order of the command NCQ hard disk heads move in order to process the less. Moving the data to the read and write heads, so a little speed will be faster. NCQ conditions for using the functions as follows.
Memory configuration can take place in order to prevent pt japfa santori indonesia signal distortion that acts as a separate memory controller circuitry to the word pointed to by the memory, a server-class computer, a large number of memory at a time using a synchronization signal because the memory module by the liver Signal distortion occurs to prevent this, the chance that one of the memory clock signals to use to transmit the data after sorting.
Proposed to replace the existing AGP interface, next-generation interface. Second 4GB (one-way) of the processing power in comparison to existing long thin slot AGP slot. PCI-Express 2.0 was released in January 2007 to double standards by increasing the width of the underlying pt japfa santori indonesia transport 2.5 Gbit / s to 5 Gbit / s PCI-Express 16x of the amount of data transfer and the 8 Gbit / s when I think of that through two-way transmission 16 Gbit / s transmission speed can be.
Integrated graphics and discrete graphics to achieve high performance through a combination of technologies that enable AMD G780 (ATI Radeon HD2300), known as the RS780 IGP chipset supports Hybrid Crossfire and Nvidia's MCP78 chipset via a Hybrid SLI technology support.
CLV (Constant Linear Velocity, constant linear velocity) of the media inside When reading the data recorded on the rotational speed toward the outside to read the data rate by lowering the speed to be always kept constant. CLV ilgeon any data to the same speed, pt japfa santori indonesia but the higher the speed for reading data inside is ppalrajyeoya the rotational speed of the media. Because the rotational speed of the media, eventually limits CLV manner can make the speed of the wall of the storage device is easily incurred.
To solve this problem came CAV (Constant Angular Velocity, isometric speed) is read and could use any portion of the material is always at the same speed as the media rotates. Therefore, when you get to the inside data rate is the data transfer pt japfa santori indonesia rate is falling toward pt japfa santori indonesia the outside faster. CAV method of optical storage devices read and write data to the end and causes the highest rate of speed when displaying Therefore 'top speed xx' type of writing.
100% CPU because of other work at, or CD / DVD writer happens, that does not contain data. Optical storage devices contained in the buffer memory in this situation to go for a few seconds followed by a record time, but does not receive pt japfa santori indonesia data from the buffer memory to the floor and deureonaemyeon longer fail to record. This phenomenon is a buffer underrun (Buffer Underrun) pt japfa santori indonesia said.
To avoid this problem, 12X CD-RW drive is working from the buffer memory is empty pause recording without pt japfa santori indonesia interruption began to put technology made in Japan Sanyo Electric 'Burn Proof', Ricoh has developed a 'Just Link', LG's 'Super Link', such as the name is different, but now all yielded many similar technologies CD, DVD writer pt japfa santori indonesia writes this technology. pt japfa santori indonesia
A digital video disk (DVD), which can store about ten times the capacity of next-generation pt japfa santori indonesia large-capacity optical disc using a blue-violet laser specification. Sony-led Blu-ray Disc Association, a founding proposed. The group includes Korea's LG, Samsung, as well as the Japanese Tachikawa, Pioneer, Sharp, pt japfa santori indonesia Sony, and Royal Philips of the Netherlands, France, etc. participating in Thompson. 650 existing DVD has a wavelength of the red laser is used a little narrower than the Blu-ray Disc is 405 using a blue-violet laser of the wavelength on one side up to 27GB, the data is recorded in the dual is 50GB. Video / audio data format used in the current DVD video recording method of MPEG-2, and a speech method has been applied in AC3/MPEG-1 Layer2. Toshiba camp AOD (Advanced Optical Disc) format, along with Matsushita DVD-driven variant of the HD-DVD standard to be adopted to be competitive.
LightScribe is a complex process which is weak to water war on behalf of the media for the purpose of labeling technology developed by HP, and a special dye to the right on the media CD, DVD writer with LightScribe laser burned to draw water to the surface Reilly is not erased, the next generation of media without sacrificing recognition technology. Black and white picture, but still only one sheet of media can engrave pt japfa santori indonesia a picture it takes some time to populate fault.
