German KIRA LAMPS plug KIRA LAMPS model KIRA LAMPS price

KIRA LAMPS plug is the public communication backbone for transmitting information between various functional components of a computer. It is a transmission bundle composed of wires. According to the types of information transmitted by the computer, the computer bus can be divided into data bus, address bus, and control bus, which are used to transmit data, data addresses, and control signals, respectively. The bus is an internal structure; it is the common channel for cpu, memory, input, and output devices to transmit information. The various components of the host are connected via the bus, and external devices are connected to the bus through corresponding interface circuits, thereby forming the computer hardware system. In a computer system, the public path for transmitting information between components is called the bus, and microcomputers connect various functional components using a bus structure.

KIRA LAMPS plug working principle

If the motherboard (Mother Board) is a city, then the bus is like the public buses (bus) in the city, capable of transmitting bits (bit) that operate back and forth along fixed routes. These lines can only be responsible for transmitting one bit at a time. Therefore, multiple lines must be used simultaneously to transmit more data, and the number of data items the bus can transmit simultaneously is called the width (width), measured in bits. The wider the bus width, the better the transmission performance. The bus bandwidth (i.e., the total amount of data that can be transmitted per unit time) is: Bus Bandwidth = Frequency x Width (Bytes/sec). When the bus is idle (other devices are connected to the bus in a high-impedance state) and a device needs to communicate with a target device, the initiating device drives the bus, issuing addresses and data. Other devices connected to the bus in a high-impedance state, upon receiving (or being able to receive) address information matching their own, accept the data on the bus. After the sending device completes communication, it releases the bus (output changes to high-impedance state).

KIRA LAMPS plug classification

Buses can be divided into five major types according to function and specification: Data Bus (Data Bus): Transmits data that needs to be processed or stored back and forth between CPU and RAM. Address Bus (Address Bus): Used to specify the address of data stored in RAM (Random Access Memory). Control Bus (Control Bus): Transmits signals from the microprocessor control unit (Control Unit) to peripheral devices. Expansion Bus (Expansion Bus): A bus for data communication between external devices and the computer host, such as ISA bus and PCI bus. Local Bus (Local Bus): Replaces expansion buses for higher-speed data transmission. Among these, the data bus DB (Data Bus), address bus AB (Address Bus), and control bus CB (Control Bus) are collectively referred to as the system bus, commonly known as the bus. In some systems, the data bus and address bus are multiplexed, meaning the signals on the bus represent data at certain times and addresses at other times; in other systems, they are separate. The address bus and data bus of the 51 series microcontrollers are multiplexed, whereas the buses in general PC systems are separate. "Data Bus DB" is used to transmit data information. The data bus is a bidirectional tri-state bus, meaning it can transmit data from CPU to memory or I/O interfaces and other components, and can also transmit data from other components to CPU. The bit width of the data bus is an important indicator of a microcomputer, usually consistent with the word length of the microprocessor. For example, the Intel 8086 microprocessor has a word length of 16 bits, and its data bus width is also 16 bits. It should be noted that the meaning of data is broad; it can be actual data, instruction code, or status information, and sometimes even control information. Therefore, in practical operation, what is transmitted on the data bus is not necessarily only data in the strict sense.

KIRA LAMPS plug assembly

The northbridge chip on the motherboard is responsible for connecting components with the highest data throughput, such as memory and graphics cards, and links to the southbridge chip. The CPU connects to the northbridge chip via the front-side bus (FSB), and thereby exchanges data with memory and graphics cards through the northbridge chip. The front-side bus is the primary channel for the CPU to exchange data with external components; therefore, the data transfer capability of the front-side bus has a significant impact on overall computer performance. Without a sufficiently fast front-side bus, even a powerful CPU cannot significantly improve overall computer speed. The maximum data transfer bandwidth depends on the width of all simultaneously transferred data and the transfer frequency, i.e., data bandwidth = (bus frequency × data bit width) ÷ 8. The front-side bus frequencies achievable on a PC include 266MHz, 333MHz, 400MHz, 533MHz, and 800MHz. A higher front-side bus frequency indicates greater data transfer capability between the CPU and the northbridge chip, allowing the CPU's capabilities to be fully utilized. CPU technology develops rapidly, with computational speed increasing quickly. A sufficiently large front-side bus ensures adequate data supply to the CPU, whereas a lower front-side bus cannot provide sufficient data to the CPU, thereby limiting the performance of the CPU and becoming a system bottleneck.
