Qhov zoo ntawm LANs:
- Cov peev txheej kim xws li tshuab luam ntawv tuaj yeem muab faib los ntawm txhua lub khoos phis tawj.
- Central thaub qab khw tuaj yeem muab rau hauv ib qho chaw (cov neeg rau zaub mov tshwj xeeb) yog li txhua txoj haujlwm tau txais kev cawmdim ua ke.
- Software tuaj yeem sib qhia, thiab kev hloov kho dua tshiab tau yooj yim dua thiab.
Tsis tas li ntawd, qhov zoo ntawm LAN yog dab tsi?
Qhov zoo ntawm LAN : Cov chaw ua haujlwm tuaj yeem faib cov khoom siv peripheral xws li tshuab luam ntawv. Qhov no yog pheej yig dua yuav lub tshuab luam ntawv rau txhua qhov chaw ua haujlwm. Cov chaw ua haujlwm tsis tas yuav xav tau lawv tus kheej hard disk lossis CD-ROM drives uas ua rau lawv pheej yig dua los yuav dua ib leeg PCs.
Tsis tas li ntawd, cov kev txwv ntawm LAN yog dab tsi? Ib yam LAN thev naus laus zis tuaj yeem hla, feem ntau, ob peb puas meters. LANs tsis yog tsim los rau kev deb. Qhov xav tau kev ncaj ncees nkag mus rau hauv cov xov xwm sib koom xws li Ethernet thiab token nplhaib txwv qhov loj ntawm a LAN . - CSMA / CD tsis ua haujlwm txaus siab thaum lub network loj dhau.
Ntawm no, qhov zoo thiab qhov tsis zoo ntawm LAN thiab WAN yog dab tsi?
Qhov kev ncua deb ntxiv, lub network qeeb qeeb. Ib tug loj qhov tsis zoo kom muaj ib WAN yog tus nqi nws tuaj yeem tshwm sim. Muaj tus kheej WAN tuaj yeem kim.
| Qhov zoo | Qhov tsis zoo |
|---|---|
| Tso cai rau ntau qhov loj dua thiab sib txuas ntau dua tuaj yeem npog ze ntawm thaj chaw tsis kawg | Tus nqi nrawm yooj yim ntawm kev siv |
Vim li cas LAN tseem ceeb?
LAN yog qhov tseem ceeb rau kev sib koom nrog cov ntaub ntawv servers, cov tshuab luam ntawv thiab cov ntaub ntawv khaws cia. LAN kho vajtse xws li ethernet cables thiab hubs yog pheej yig kom tau txais thiab tswj. Me me LANs tswj 2 lossis 3 lub computer thaum loj LANs host ntau txhiab tus servers. Kev sib txuas hauv Is Taws Nem tuaj yeem yog wired lossis wireless.

Dab tsi yog qhov piv txwv ntawm qhov zoo nrog rau qhov zoo network sab nraud cuam tshuam?
Cov piv txwv classic yog xov tooj, qhov twg ntau tus neeg siv nce tus nqi rau txhua tus. Qhov zoo sab nraud yog tsim thaum lub xov tooj tau yuav yam tsis muaj nws tus tswv xav tsim kom muaj txiaj ntsig rau lwm tus neeg siv, tab sis ua li ntawd txawm tias
Dab tsi yog qhov txawv ntawm kev sib raug zoo unary kev sib raug zoo binary thiab kev sib raug zoo ternary?
Kev sib raug zoo tsis sib xws yog thaum ob tus neeg koom hauv kev sib raug zoo yog tib lub koom haum. Piv txwv li: Cov ncauj lus yuav yog qhov yuav tsum tau ua ua ntej rau lwm yam kev kawm. Kev sib raug zoo ternary yog thaum peb lub koom haum koom nrog kev sib raug zoo
Dab tsi yog sparse kem Dab tsi yog qhov zoo thiab qhov tsis zoo?
Koj poob 4 bytes tsis yog ib zaug ib kab; tab sis rau txhua lub cell hauv kab uas tsis yog null. Qhov zoo ntawm SPARSE kem yog: Qhov tsis zoo ntawm SPARSE kem yog: SPARSE kem tsis tuaj yeem siv rau ntawm cov ntawv, ntext, duab, timestamp, geometry, geography lossis cov neeg siv cov ntaub ntawv teev tseg
Dab tsi yog qhov qub txeeg qub teg Dab tsi yog qhov sib txawv ntawm qhov qub txeeg qub teg piav nrog piv txwv?
Inheritance yog ib txoj hauv kev kom tau txais cov yam ntxwv thiab kev coj cwj pwm ntawm ib chav kawm los ntawm lwm chav kawm. Cov chav kawm uas cov tswv cuab tau txais qub txeeg qub teg yog hu ua chav kawm hauv paus, thiab chav kawm uas tau txais cov tswv cuab tam sim no hu ua chav derived. Inheritance siv IS-A kev sib raug zoo
Dab tsi yog qhov zoo sib xws thiab qhov txawv ntawm relays thiab PLC yog dab tsi?
Relays yog electro-mechanical keyboards uas muaj coil thiab ob hom kev sib cuag uas tsis yog NO & NC. Tab sis Programmable Logic Controller, PLC yog lub khoos phis tawj me uas tuaj yeem txiav txim siab raws li qhov kev zov me nyuam thiab nws cov tswv yim & tso tawm
