toptal vs crossover

straight-through cable means that both ends of the crystal head adopt the T568A or T568B connection method at the same time, while the crossover cable adopts the T586A standard at one end of the crystal head and the T568B standard at the other end, that is, 1 and 2 of A crystal head correspond to 3 and 6 of B crystal head, while 3 and 6 of A crystal head correspond to 1 and 2 of B crystal head. Others remain unchanged. The standard line sequence of T

ISO/IEC 7498, which defines the 7-tier framework for network interconnection, the Open Systems Interconnect Reference Model (OSI model ).A switch is like a neighboring street, and a router is the intersection of a street. (The second layer of the switch , the data link layer, also has four layer, seven layer switch; the router works on the third layer).See (http://www.he.edu.cn/learn/wlxy/netlan/index.html)Crossover and direct-attached network cablesF

This article also introduces several popular broadband networking configurations for ADSL Wireless routers. Recently, due to the migration and adjustment of its ADSL Network Mode, it was found that the original configuration can achieve broadband access to multiple computers. There is a slight difference between different methods. Note: The black line is the telephone line, the red line is the cross network cable, and the Green Line is the direct connection network cable. The first method for co

Normally, the same connector is used in the same system.

equipment manufacturers have adjusted the price of 24-port switches, and also launched some low-end non-Network-managed switches to meet the needs of small and medium-sized enterprises, currently, 24 vswitches of less than 500 RMB can be seen on the market. It is no wonder that some people use "civilian" to describe the 24-port switch products. It can be seen that the 24-port switch will soon become a mainstream product for small and medium-sized enterprises and residential users. In terms of s

simplifies the connection between switches. Uplink port is a dedicated port used to connect to other vswitches. You can use a straight-through jumper to connect the port to any port other than the Uplink port of another vswitch. The connection method is the same as that between the computer and the switch. Note that some brands of vswitches such as 3Com use a common port and Uplink port, and use an MDI/MDI-X switch) to switch between the two types. Cascade switches through Uplink ports using ex

distance is enough for a small network in the same building! Uplink ports are now available, except for more and more Cisco switches. This simplifies the connection between core switches.

But later on the internet to see, in fact, TFTP is also available, and the efficiency may be higher. The following is the way others recover, but I did not practice, because I have not entered the Rommon mode:Install the TFTP server software on a single machine, place the iOS file in the default root of the TFTP server, open the TFTP server,

Frequency divider refers to the different frequency bands of the sound signal to distinguish, respectively, to enlarge, and then sent to the corresponding band of the speakers and then replay.

Design circuit, because the serial line has been done cross, single-chip computer rxd Connection circuit board DB9 RXD, SCM TXD Connection circuit board DB9 Txd, are directly connected.This can explain why some circuits use the direct connection method, some circuits use the crossover method, because the use of the serial l

register.5. Programmable Channel Sampling time:　　The ADC uses several ADC_CLK cycles to sample the input voltage, and the number of sample cycles can be changed through the smp[2:0] bit in the ADC_SMPR1 and ADC_SMPR2 registers . Each channel can be sampled at different times, respectively.The total conversion time is calculated as follows:TCONV = Sample Time + 12.5 Cycle Period6.
