Twisted wire and shielded ba yung mga wires sa loob ng ethernet cable? I'm wondering kung pwede gamitin sa video signal ito. I don't care about the impedance at this point.

kita ko naman wala naman si palakang toti haha

ok describe konalang kapag hub straight coonect. kapag PC to PC crossover dahil magkatalikod yong 2 rj45 altered natin ang TX+,TX- RX+, RX- ibig sabihin kong ikoconnect natin ang rx+ sa tx+ vice versa ganun rin sa negative (-) sa lahat naman ng mode + man o negative straight parin ang connection ibig sabihin kapag positive sa mode positive parin nakaconnect

noong unanang panahon na wala pa ang auto sensing kinakailangan masunod ang rules about cabling configuration.

kung saan, same devices uses crossover configuration and different devices uses straight.

pero sa panahon ngayon, most devices are designed to work either cross or straight called auto sensing capability.

pero sa mga manageable na cisco routers and switches na naencounter ko, karamihan sinusunod parin ang ganyan concept na, pag same device crossover, pag not same device straight.

I concur master itong nagsabi eh.

agree tama problem lang hinde lahat ng devices ay makabago na ang design meron parin gumagamit ng mga luma, kaya para sure sundin nalang yong cabling configuration

OT:
mga sir ask ko lang po kung mabilis yung file transfer ex: is 32Gb Pc to laptop using crossover cable. kasi po ginagwa ko lang filetransfer gamit yung router(zykel pldt) medyo mabagal lang siya. mas mabilis po kaya or same lang din kung d-direct ko PC to laptop?

basic math sir... wag muna natin tackle si full or half duplex.

100mbps yung connection. that's megabits.. per second. Zero's and Ones.

let's assume yung data is sent in 8bits plus parity... assuming lang ah. ang byte natin.

11,111,111 BYTES per second ang transfer rates nya... or 11 MB/s (Megabytes per second)

now... 32 gigabytes naman ang gusto natin padaanin sa 100megabit connection.

32,000 megabytes... / 11MB/s (Megabytes per second)... 2909 seconds... in about 48 minutes na transfer na yan.

tandaan din na may CRC checking.. acknowlegdge.. encryption... atbp..

bandwidth nang SATA 2 is nasa 3.0Gigabit per second. SATA 3 is 6Gbps... so better na hard disk to hard disk na lang.
or a faster 1gbps LAN.

kya hard disk to hard disk ang mabilis.
