The key difference between hub and bridge is that hub works on the physical layer, but bridge runs on the data link layer of OSI model. Hubs and bridges have different uses. Hubs send data to each device connected to them, and it broadcasts data. On the other hand, the bridge is more intelligent, checking and filtering data before forwarding data. This mechanism can significantly reduce network traffic and improve security. Hubs can connect two LAN segments, while bridges can connect two different LANs. Differences between Hubs and Bridges BASIS FOR COMPARISON HUB BRIDGE Basics Used to connect a number of devices. Facilitates in the segmentation of the larger network. Types Active and Passive Transparent, translational and source route. Data filteration Not performed Conducted Uses Multiple ports Single incoming and outgoing port Links Segments of LAN Two different LAN employing same protocol. What is the hub? Hub is a basic network device because it provides a very simple function of establishing connections between several devices. In addition, the device can also be used as a connector for different LAN segments. These devices are connected to the hub by twisted pair cables. The main purpose of hubs is to transmit data packets to each device connected to them. It does not perform any filtering, which means that each block of data is transmitted to all connected terminal devices, even if it is not the target device. That's why it's considered a non-intelligent device. Hubs work in a single conflict area, which means that transmission lines should run at the same speed.…

DDR2 and DDR3 are DDR RAM memory versions, among which DDR3 is a more advanced version with higher functions, such as high data transmission speed, low power consumption, memory reset options, more memory, etc. But the main difference is that DDR3 provides data rates twice as fast as DDR2. As technology advances, faster memory versions, such as DDR (double data rate) memory, have also been developed. The main concept behind DDR memory is to simultaneously access a large number of bits in the chip by applying row addresses to the chip. There are several technologies that can improve bit transfer speed from pin to chip. In order to effectively utilize clock speed, data is transmitted externally to the rising and falling edges of the clock, which is why these memories are called double data rate memory. BASIS FOR COMPARISON DDR2 DDR3 Clock frequency (theoretical) 400 - 800 Mhz 800 - 1600 Mhz Transfer data rate 400 - 800 Mbps 800 - 1600 Mbps Supply voltage 1.8 volts 1.5 volts Prefetch bit width 4 bit 8 bit Memory reset option No provision of reset options Provided Power consumption High Low Speed Slower comparatively Faster Latency 2 - 5 7 - 11 Performance Better than DDR3 Average Cost Less More Definition of DDR2 DDR2 is the second version of DDR (double data rate) memory. These versions of RAM were developed to achieve high data rates for block transmission. It can transmit data at a clock rate of 400 to 106 Mhz. DDR version 2 is a follow-up version of DDR, which mainly…

Some email clients might require that you use the full address. If using just the username doesn't work, try attaching the end to the address also, to include the "@yahoo.com" section. Yahoo Mail POP password: Your Yahoo Mail password Yahoo Mail POP port: 995 Yahoo Mail POP TLS/SSL required: yes It's easy for you to type in a wrong password, which is a common reason why you can't access YAHOO mail.
