SubnettingAdvantages of network bridges
- Self configuring
- Primitive bridges are often inexpensive
- Reduce size of collision domain by microsegmentation in non switched networks
- Transparent to protocols above the MAC layer
- Allows the introduction of management - performance information and access control
- LANs interconnected are separate and physical constraints such as number of stations, repeaters and segment length don't apply
- it also helps minimize high bandwidth
Disadvantages of network bridges
- Does not limit the scope of broadcasts
- Does not scale to extremely large networks
- Buffering introduces store and forward delays - on average traffic destined for bridge will be related to the number of stations on the rest of the LAN
- Bridging of different MAC protocols introduces errors
- Because bridges do more than repeaters by viewing MAC addresses, the extra processing makes them slower than repeaters
Kemarin saya bingung artinya /24 di belakang ip tuh apa. Ternyata itu jumlah bit yang dipakai untuk mengidentifikasi ip network. Jadi klo ada tulisan /24 artinya net masknya: 11111111 11111111 11111111 0000000 = 255.255.255.0
Coba lihat, bit satunya ada 24 bit. Untuk menghitung jumlah host, tinggal di ubah aja bit-bit nol menjadi 1 dan bit 1 menjadi nol, ya itu lah total host yang tersedia. Jadi /24 akan menhasilkan jumlah host 255 (254 available)
