as the main disk. For a simple example, you had a Ⅱ20GB hard drive (7200 RPM) and later acquired a 60GB Seagate U6 hard Drive (5400 rpm), so you should set the cool fish ⅱ20gb as the main dish because it's faster.
The jumper methods between different hard disks may differ, but they are basically the same. Let's take a piece of Seagate's Cool fish Ⅳ (7200 rpm) and a one-step star-Diamond generation (5400 rpm) to explain how the jumper is
, but according to the board manufacturer's product development plan, a 28, 36-Port Extender will be introduced in the future to connect SAS devices, host devices, or other SAS extenders.
Compared with the traditional parallel SCSI interface, SAS is not only significantly increased in interface speed (now the mainstream ultra-320mb/sec SCSI speed is the same, and the SAS just start to reach 300mb/sec, the future will reach 600mb/sec or more), And because of the use of serial cable, not only can
Sata's full name is serial Advanced Technology attachment (Serial Advanced technology Attachment, an industry-standard serial Hardware driver interface), which is made up of Intel, IBM, Dell, APT, The hard disk interface specification proposed by Maxtor and Seagate Corporation. The Serial ATA 1.0 specification was formally established in 2001 by the Serial ATA Board of Intel, APT, Dell, IBM, Seagate, and th
Seagate Hard Drive, and then upgraded with a 128M memory, configured with a built-in 56KMODEM and TV card, The fault appeared. Specific performance for the system started shortly after the crash, the monitor black screen no signal, the optical drive light long bright. Whether into the WIN98 system, with the system disk boot, or into the CMOS system will appear this fault, once the crash either reset key or power button can not shutdown, only pull the
hurricane.
Two. Implementation of IDE RAID via hardware control chip
RAID 0 and RAID 1 are the most widely used personal computers in a raid family, and there are few individual users willing to use 4 or more hard disks to build a RAID 0+1 or other hard disk array, so we'll just explain these two raid modes here. We choose to support the Ide-raid function of the Kt7a-r aid motherboard, step-by-step to introduce the installation of Ide-raid. The Kt7a-raid integrates the Highpoint 370 chip, whi
BIOS upgrade failed or a virus such as CIH caused the system to fail to start it was terrible. In the PC horn two short screams, floppy drive a strange call, the computer will be black screen to indicate that he now refuses to work.
Let me say one of the safest ways to restore the BIOS without spending a penny.
BIOS upgrades for my computer I've done it no less than 30 times, without fail. But today ... The thing is, one of my classmate's 80G Seagate
:
The current graphics card is divided into independent and integrated graphics, the production of independent graphics chips are mainly 2 manufacturers monopoly, NVIDIA and ATI, production integrated graphics chip has inter,nvidia,ati,sis and so on. Major graphics card manufacturers to use the graphics card chip provided by the GPU graphics card design and assembly .
Memory:
At present all the memory of the particles are made abroad, mainly made in Korea. Domestic production is only PCB bo
, and the idea is equally questionable.
The first recommendation is not that important. I went to Zhongguancun to buy hard disk, on the zol to see the comments said West hard disk is better, the cheapest price, so I went, but to the shop, I found that we all buy Seagate, eventually I also bought Seagate; I am going to spend 500 yuan to buy a mobile phone, see comment say Nokia is good, so go to the handset
Full HD IPS screen, The three main power consumption components are all high-performance products, can have more than 4 hours of performance is very rare. And in the more stringent powermark endurance test, N550 performance is worse, eventually in 166 minutes to consume 81% of the power, the conversion of which means that all 100% power can support about 198 minutes or so, The test system takes into account the actual use of the user and the machine sleep to save data, such as the required powe

original exception point, but the compiler will warn that the defined ex is not used:
View code

Third, without exception parameters, this is the same as the second one. All types of exceptions can be captured without the IDE warning:
View code
Try{}Catch{Throw;}
In fact, the second and third usage are not recommended in the book. Generally, we should start from small-granularity exception capture and adopt multiple catch statements...
