Muaj plaub hom ntawm coding : Cov ntaub ntawv compression (los yog qhov chaw coding ) yuam kev tswj (los yog channel coding ) Cryptographic coding.
Tib neeg kuj nug, dab tsi yog coding system?
1. coding system -a qhov system ntawm cov cim siv los sawv cev rau cov tsiaj ntawv lossis cov lej hauv kev xa xov. code -a coding system siv los xa cov lus xav tau brevity lossis secrecy.
Ib yam li ntawd, koj nkag siab dab tsi los ntawm coding schemes? Coding schemes yog txoj kev categorizing cwj pwm li ntawd koj tuaj yeem code dab tsi koj saib nyob rau hauv cov nqe lus ntawm ntau npaum li cas ib hom kev coj cwj pwm tshwm. Qhov zoo ntawm hom kev soj ntsuam no yog tias yog tias koj yog kawm tej yam kev coj cwj pwm lawv muaj siab ecological validity.
Ib yam li ntawd, nws yog nug, dab tsi yog peb lub tshuab coding nrov tshaj plaws los sawv cev cov ntaub ntawv?
Ntawm no peb yuav kawm txog nrov coding systems , siv rau sawv cev cov ntaub ntawv . Cov coding systems suav nrog Binary, Octal, Hexadecimal, BCD thiab American Standard Code for Information Interchange (ASCII), Grey code, Tshaj. peb cov lej.
Peb hom coding yog dab tsi?
Cov lej yog siv rau cov ntaub ntawv compression, cryptography, yuam kev nrhiav thiab kho, xa cov ntaub ntawv thiab cov ntaub ntawv khaws cia.
Muaj plaub hom coding:
- Cov ntaub ntawv compression (los yog, qhov chaw coding)
- Kev tswj yuam kev (los yog channel coding)
- Cryptographic coding.
- Kab coding.
