MB vs GB
MB thiab GB yog cov ntsiab lus uas niaj hnub no txawm siv los ntawm cov txiv neej uas tsis paub lub ntsiab lus tiag tiag ntawm nws. Yog tias koj xav tias baffled los ntawm cov lus KB, MB thiab GB, tsis tas yuav tsum yog vim lawv tsuas yog cov lej uas qhia cov ntaub ntawv ntau lossis lub peev xwm ntawm lub computer khaws cov ntaub ntawv. Tawm ntawm peb chav nyob ntawm kev ntsuas qhov loj ntawm cov ntaub ntawv, KB (Kilo bytes) yog qhov tsawg tshaj plaws thiab GB (Giga bytes) yog qhov loj tshaj plaws txawm tias niaj hnub no muaj cov chav loj dua xws li TB (Tera bytes) tau siv nrog puas tau nce lub cim xeeb. ntawm computers. Qhov sib txawv ntawm MB (Mega bytes) thiab GB yog qhov yooj yim to taub yog tias koj sim nkag siab nws ib yam li koj tau kawm kev ntsuas hauv SI system.
Hauv lej, peb muaj tus lej uas yog 0-9 thiab siv tus lej lej. Tab sis nyob rau hauv computers, hluav taws xob Cheebtsam yog nyob rau los yog tawm, thiab li no tsuas muaj ob tug lej 0, thiab 1. Yog li nws yog ib tug binary system nyob rau hauv lub computer. Ntsis yog chav tsev me tshaj plaws hauv computers thiab nws tuaj yeem muaj ob qho txiaj ntsig 0 lossis 1.
Byte yog ib txoj hlua ntawm 8 khoom (8 qhov muag teev ua ke). Qhov no yog qhov chaw me tshaj plaws uas cov ntaub ntawv ua tiav hauv computers. Tus nqi loj tshaj ntawm byte yog 2X2X2X2X2X2X2X2=256, thiab los sawv cev cov lej loj dua, peb yuav tsum siv KB.
Tom ntej los KB uas yog 2X2X2X2X2X2X2X2X2X2=1024 bytes. Qhov no kuj tseem hu ua 1000 bytes hauv metric system. Kom meej meej binary KB loj dua kaum KB.
MB yog 2 muab 20 npaug lossis 1048576 bytes. Hauv cov lej lej nws yuav yog 10000000.
GB yog 2 muab 30 zaug lossis 10737741824 bytes lossis 1 billion bytes. Qhov no yog thaum zoo li muaj qhov sib txawv ntawm binary thiab decimal system.
Qhov laj thawj vim li cas tib neeg tsis meej pem ntawm MB thiab GB yog tias qee cov tuam txhab siv binary system thaum lwm tus siv cov lej lej. Thaum koj yuav ib lub hard disk, lawv qhia koj tias nws yog 100GB, tab sis thaum koj nruab thiab muab faib rau hauv A, B, C, thiab D, koj lub computer tsis qhia lawv lub peev xwm li 25 GB txhua tab sis me ntsis tsawg dua qhov no. Qhov no tshwm sim vim tias koj lub khoos phis tawj suav cov peev txheej khaws cia hauv binary system thaum cov neeg muag lub hard drive suav nws hauv cov lej lej. Qhov no tsuas yog txhais tau tias yog tias koj muaj 100GB ntawm cov ntaub ntawv khaws cia hauv koj lub computer, koj xav tau tsawg kawg 110 GB ntawm qhov chaw hauv lub hard drive.
Summary
MB thiab GB yog cov ntsuas ntsuas uas ntsuas lub peev xwm ntawm cov ntaub ntawv. Lawv yeej qhia koj tus lej ntawm cov ntaub ntawv uas lawv muaj.
MB hais txog ib lab bytes hauv cov lej lej thaum nyob hauv binary system nws sawv ntawm 1024576 bytes.
GB hais txog ib txhiab bytes hauv cov lej lej thaum nyob hauv binary system nws txhais tau tias 10737741824 bytes.
Kev nkag siab yooj yim dua, koj tuaj yeem xav txog MB li ib grams thiab GB li ib kilo.
