Now, the rapid development of the network has entered the G era, and gigabit network transmission equipment is not a new thing. However, as high-end equipment, they also have "high-end" price. Just like the following this original imported Lucent Gigabit network cable, 2 meters long, but to hundred yuan price, if it is ordinary hundred gigabit cable, 4 yuan is enough. Today, I reluctantly give it to everyone to a full anatomy, let us see what it is special in the end.

various texts, tables, documents, etc. do not contain executable files. Other programs are required to open the data and are placed in the data partition. This way, even if the system is paralyzed and has to be reinstalled, the available programs and data are not missing, and can quickly resume work without having to worry about recovering data for the program.

Reason: It should
What is the storage unit of a computer?
Computer storage units are generally expressed in bit, Byte, KB, MB, GB, TB, PB, EB, ZB, BB,
We often refer to the byte abbreviation as B and ask K for the KB abbreviation. What a few k, what a few B.
Two, what is their conversion relationship? 1, the smallest unit in which the computer stores information: bit bit (bit) (Binary Digits): holds a binary number, that is, 0 or 1, the smallest storage unit. 2, computer storage capacity basic unit is by
Bit and byte
> The speed is bit, And the size is byte. (It is best to distinguish bit byte from Upper/lower case)
> Bit, bit, basic unit of computer operation, which is the unit of length of the binary number; e.g. 10011001 is an 8-bit binary number; BPS = bits per second number of transmitted bytes per second;Byte bytes, the basic unit of measurement for computer storage space; e.g. 480 standard interface transmission rate MBS: megabits/S = 60 megabits/s;
> One byte is stored in a computer as

MMX: Short for multimedia extensions (multimedia extensions), is an important feature of the sixth generation of CPU chips. MMX technology is added to the CPU with 57 commands specially designed for video signals (video signal), audio signals (audio signal), and image processing (graphical manipulation). Therefore, the mmx cpu greatly improves the computer's multimed

% of the partition capacity, the G1 collector thinks it is a giant object. These mega objects, by default, are allocated directly to older generations, but if it is a short-lived mega-object, it can have a negative impact on the garbage collector. To solve this problem, G1 divides a humongous area, which is used to store giant objects. If an H-zone does not contain a giant object, then G1 will look for cont

So the precise measure is measured by a higher level of technical staff in the industry. The main measures are:
1. Architecture capability of medium system.
2. The relationship between system architecture and division of labor.
3. Software Quality assurance system and methods.

The right thing to do is to install the programs that need to copy files and write data in the System folder and registry into the system partition; For those programs that can be installed in a green installation, files that can be run only by installing folders are placed into the program partition, and the various texts, tables, documents, etc. do not contain executable files.

Bit means "bit" or "bit", which is the basis of computer operation and belongs to the areas of binary system.
byte meaning is "bytes", is the computer file size basic unit of calculation;
The two applications are different. Bit is usually used as the unit of data transmission, because the physical layer, the data link layer transmission is transparent to the user, and this communication transmission is based on binary transmission. In the application tier, it is usually a byte to indicate the si

fiber
Optical fiber by virtue of its small quality, large capacity, transmission frequency bandwidth and other features become the first choice for gigabit Ethernet applications. Although the single mode optical fiber can meet this requirement, it needs to use the laser light source, the corresponding optical transceiver cost is also very high. The common multimode fiber can only meet the following applications, can not meet the requirements of high-speed Ethernet. After research, the industry

At present, more and more manufacturers to enter the Ethernet market, new brands and new products continue to emerge, it seems that there has been a trend of homogenization of competition. However, it is worth mentioning that the Ethernet switch in the market number of expansion, while the quality requirements are also constantly improving. Just to meet the simple connection and data transmission function, obviously can not adapt to future needs. Cisco believes

Use a global optimization method similar to [14] for the texture synthesis work. By stitching overlapping image blocks together to get the super-pixel, each pixel belongs to only one of the overlapping regions. This method has two variants, one for generating compact hyper-pixels (GCA10) and one for constant-intensity hyper-pixels (GCB10). B. Gradient-based approach
