4.19.2. Bluetooth Antenna Interface (Only SIM800H) The SIM800H module provides a Bluetooth antenna pad named BT_ANT.
The external antenna must be matched properly to achieve best performance, so the matching circuit is necessary,
the connection is recommended as in the following figure:
Figure 51: Bluetooth antenna matching circuit R201, C201, C202 are the matching circuit, the value should be defined by the antenna design. Normally R201 is
1.2nH, C202 is 1.5pF and C201 are not mounted.
There are some suggestions for placing components and RF trace lying for GSM and Bluetooth RF traces:
z The RF connector is used for conducted test, so keep it as close to pin GSM_ANT as possible;
z Antenna matching circuit should be closed to the antenna;
z Keep the RF traces as 50Ω;
z The RF traces should be kept far away from the high frequency signals and strong disturbing source.

4.19.1. GSM Antenna Interface
There is a GSM antenna pad named GSM_ANT for SIM800H&SIM800L, the connection of the antenna must be
decoupled from DC voltage. This is necessary because the antenna connector is DC coupled to ground via an
inductor for ESD protection.
The external antenna must be matched properly to achieve best performance, so the matching circuit is necessary,

5.2 Principle of PCB Layout
During layout, attention should be paid to the following interfaces, like Antenna, power supply, SIM card
interface, audio interface, and so on.
5.2.1 Antenna Interface
z The length of trace between pin output and connector should be as short as possible;
z Do not trace RF signal over across the board;
z The RF signal should be far away from SIM card, power ICs.
Power Supply - Sim800l simcom

|
Sim800l simcomBog'liq SIM800L5.2.2. Power Supply
z Not only VBAT but also return GND are very important in layout;
z The positive line of VBAT should be as short and wide as possible;
z The correct flow from source to VBAT pin should go though Zener diode then huge capacitor;
z Pin 2, Pin 43, Pin 44 and Pin45 are GND signals, and shortest layout to GND of power source
should be designed;
z There are 12 GND pads in middle of module; these pads could enhance the GND performances. On
the upper layer of these pads, do not trace any signal if possible.
5.2.3 SIM Card Interface
z SIM card holder has no anti-EMI component inside. Thus SIM card interface maybe interfered,
please pay more attention on this interface during layout;
z Ensure SIM card holder is far way from antenna or RF cable inside;
z Put SIM card holder near the module, as nearer as possible;
z Add ESD component to protect SIM_CLK, SIM_DATA, SIM_RST and SIM_VDD signals which
should be far away from power and high-speed-frequency signal.
5.2.4 Audio Interface
z The signal trace of audio should far away from antenna and power;
z The audio signal should avoid to parallel with VBAT trace.
5.2.5 Others
It is better to trace signal lines of UART bunched, as well as signals of USB.

yong'in o'chirish vositalarining fotosurati
Asosiy talabni yongʻinga olib kelishi va inson va moliyaviy yoʻqotishlarga olib kelishi mumkin boʻlgan barcha jarayonlarni nazorat qilish va tekshirish deb atash mumkin.
Biroq, yongʻin paydo boʻlishining oldini olishga yordam beradigan bir qator talablar mavjud, xususan:
mehnat muhitida yonuvchi moddalarning ruxsat etilgan kontsentratsiyasi uchun belgilangan me'yorlarga muvofiqligi;
materiallarning yonuvchanligini kamaytiradigan qo'shimchalardan foydalanish (ingibitor va flegmatizatsiya);
havo muhiti tarkibini kuzatish va nazorat qilish;
Yonuvchi va portlovchi xavfli ish muhitining oldini olish;
sanoat binolarini to'g'ri ventilyatsiya qilishning mavjudligi;
favqulodda vaziyatlarda xabar berish uchun ish holatida yongʻin signalizatsiyasining mavjudligi.
Yong'in xavfsizligi tizimlarini yaratish muayyan ishlab chiqarish jarayoni uchun me'yoriy-texnik hujjatlar talablariga muvofiq amalga oshirilishi kerak. Bundan tashqari, darajani hisobga olish kerakmuayyan ishlab chiqarishda ishlatiladigan materiallarning yonuvchanligi.
Amaliyot shuni koʻrsatadiki, yongʻin sodir boʻlishining toʻliq oldini olishning iloji yoʻq, ammo yaxshi rejalashtirilgan ogohlantirish tizimi orqali salbiy oqibatlarni kamaytirish uchun hamma narsani qilish bizning qoʻlimizda.

Agar goto operatori bo‘lmaganida dasturning ichki qismidan chiqish uchun yuqoridagi dasturda uchta ifvabreak ko‘rsatmalariga murojaat qilish kerak edi.Bundayholda,gotooperatori kodni soddalashtiradi. Yuqoridagi misol faqat goto operatoridan foydalanishni ko‘rsatish uchun bo‘lsa-da, goto operatori foydali bo‘lishi mumkin bo‘lgan holatlar juda ham ko‘p.

# Takrorlash operatori (While, Do While)
C# tilidagi yana bir sikl ifodasi while ifodasidir. Quyida ushbu operatorning umumiy shakli keltirilgan:
2.2 while (shart) operator;
bu yerda operator bitta operator yoki operatorlar bloki bo'lib, shart siklni boshqarish uchun maxsus shartni bildiradi va har qanday mantiqiy ifoda bo'lishi mumkin. Bu siklda, shart rost bo'lsa, operator bajariladi. Shart yolg’on bo'lishi bilan dasturni boshqarish sikldan keyin darhol kod qatoriga o'tkaziladi.
For siklida bo'lgani kabi, while sikli ham sikl boshida ko'rsatilgan shartli ifodani tekshiradi. Bu shuni anglatadiki, siklning tanasidagi kod umuman bajarilmasligi mumkin, shuningdek, siklning o'zidan oldin alohida tekshirishni amalga oshirish zaruriyatini yo'q qiladi.
C# tilidagi uchinchi sikl operatori do-while operatoridir. Shart sikl boshida tekshirilgan for va while operatorlaridan farqli o'laroq, do-while operatorida siklning bajarilishi sharti eng oxirida tekshiriladi. Bu shuni anglatadiki, do-while sikli har doim kamida bir marta bajariladi. Quyida do-while sikl operatorining umumiy shakli keltirilgan.
do {
operatorlar;
} while (shart);
Agar faqat bitta operator bo'lsa, bu belgida sistemali qavslar ixtiyoriy. Biroq, ular ko'pincha do-while konstruktsiyasini while sikli konstruktsiyasi bilan adashtirmaslik qavslarni qo’yib ishlatiladi. Do-while sikli shartli ifoda yolg’on boʻlguncha ishlaydi.
C# dagi goto operatori shartsiz o'tish operatoridir. Dasturda goto operatoriga duch kelganda, bajarilish to'g'ridan-to'g'ri ushbu operator ko'rsatgan nuqtaga o'tadi. Goto operatorining dasturlash nuqtai nazaridan asosiy kamchiligi shundaki, u dasturni chigallashtiradi va uni deyarli o'qib bo'lmaydi. Ammo ba'zida goto iborasidan foydalanish dastur oqimini chalkashtirib yuborishdan ko'ra aniqlashtirishi mumkin.

Shuni yodda tutingki, Bu yerda, case bo‘limlari break operatori bilan tugamaydi. goto operatori bir case bo‘limidan ikkinchi case ga ketma-ket o‘tishga to‘sqinlik qilganligi sababli “xatolik” keltirib chiqarmaydi va shuning uchun bu holatda break operatoridan foydalanish zarurati yo‘q.

1-rasm. “Nuqtalar” metodikasi
Bunda o‘quvchilarga o‘qituvchi tomonidan mavzu bo‘yicha avvaldan tayyorlab qo‘yilgan savol
o‘rtaga tashlanadi. 1-rasmda keltirilgan yoki ixtiyoriy shaklda bosh savol atrofida nuqtalar qo‘yiladi. Har bir
nuqtada o‘rtaga tashlangan muammoning kelib chiqishiga yoki uning yechimiga ta’sir ko‘rsatgan omillar
o‘quvchilar ishtirokida belgilanadi. Misol uchun berilgan savolda 2-jahon urushining yakuniga ta’sir qilgan
voqea-hodisalar sifatida o‘quvchilar tomonidan Germaniyaning 1941-yil 22-iyundagi SSSR ga hujumi,
1941-yil dekabrda AQSh ning Germaniya va uning ittifoqchilariga urush e’lon qilinishi, 1943-yil fevraldagi
Germaniyaning 6-armiyasining Stalingraddagi mag‘lubiyati, 1944-yil 6-iyundagi 2-frontning ochilishi,
1945-yil 6-9-avgustda AQSh tomonidan Yaponiyaning Xirosima va Nagasaki shaharlariga tashlagan atom
bombalari kabi javoblar berildi. Bu kabi metodlardan foydalanish tarix fanini o‘qitishda o‘quvchilarning
tahliliy kompetensiyasini shakllantirish orqali o‘quvchilarning mantiqiy va tizimli fikrlashi, maʼlumotlarni
qayta ishlash hamda tahlil qilish kompetensiyalarini shakllantirishga yo‘naltirilgan bo‘lishi muhim
hisoblanadi. Umuman olganda, tarix fanidan ta’lim jarayonida o‘quvchilarning tahliliy kompetensiyasini
shakllantirish metodikasi quyidagi bosqichlarda amalga oshirildi [9]:
1) o‘quvchilarning mantiqiy fikrlashini ko‘p funksiyali topshiriqlar tizimini ishlab chiqish asosida
takomillashtirish;
2) o‘quvchilarning tizimli fikrlashini Blum taksonomiyasi asosida rivojlantirish;
3) o‘quvchilarning ma’lumotlarni qayta ishlash, tahlil qilish ko‘nikmalarini didaktik birliklarning
semantik tizimini qurish va pedagogik shart-sharoitlarni ta’minlash asosida takomillashtirish.
Xulosa. Yuqorida ko‘rsatilgan usullarni qo‘llash umumtaʼlim maktablarida tarix fanini o‘qitishning
interfaol metodlari va klaster metodidan foydalanish o‘quvchilarning tahliliy kompetensiyasini
shakllanganlik darajasini oshirishga xizmat qildi. Bundan tashqari umumtaʼlim maktablarida tarix fanini
o‘qitish asosida o‘quvchilarning tahliliy kompetensiyasini shakllantirish metodikasi tarix fanini o‘qitishda
ustuvorlik beruvchi innovatsion taʼlim metodlaridan biri sifatida “Nuqtalar” metodi ishlab chiqildi. Bunda
tarix fanini o‘qitish jarayonida o‘quvchilarning tahliliy kompetensiyasini shakllantirish metodikasi mantiqiy
va tizimli fikrlash, ma’lumotlarni qayta ishlash, tahlil qilish ko‘nikmalarini vitagen ta’lim integratsiyasini
ta’minlashning ustuvor yo‘nalishlari vositasida shakllantirish asosida takomillashtirildi.
Tadqiqot natijalari asosida umumtaʼlim maktablari yuqori sinf o‘quvchilarida tahliliy
kompetensiyalarni shakllantirishda elektron taʼlim vositalaridan foydalanish bo‘yicha metodik qo‘llanmalar
yaratish, tarix fanini o‘qitishda o‘quvchilarda tahliliy kompetensiyalarni shakllantirish va rivojlantirish,
mustaqil ishlash ko‘nikmalarini rivojlantirish bo‘yicha ilmiy-tadqiqotlar olib borish kerakligi bo‘yicha ilmiy-
metodik tavsiyalar ishlab chiqildi.

Jurnal 001-yilda tashkil etilgan. Jurnal yilda 12 marta chiqadiBog'liq 11-son PM Ped PsixoloMetodlar. Ma’lumki, jamoat xavfsizligini ta’minlash yo‘nalishi kursantlarida aholi bilan muomala,
muloqot, munosabatga kirishishda yuqorida ko‘zga tashlangan qator muammolar yuzaga kelishi ularning
yechimi bilan bog‘liq masalalarni ilgari surish imkoniyatini beradi. Shu nuqtai nazardan olganda
kursantlarda kommunikativ kompetentlikni shakllanganlik darajasini o‘rganish maqsadida L.Mixelson
tomonidan ishlab chiqilgan “Kommunikativ malakalar” testidan foydalanildi. Ushbu metodika kursantlarda
kommunikativ ko‘nikmalar va kommunikativ kompetentlikni shakllanganlik darajasini aniqlashga imkoniyat
yaratadi.
Natijalar. Mazkur metodika tanlab olingan sinaluvchilar guruhida o‘tkazilib, natijalar miqdor va sifat
jihatidan tahlil qilindi. Natijalarni ko‘rgazmali ifodalash maqsadida jadvallarda aks ettirildi.

Jadvalda ko‘rsatilgan natijalarga ko‘ra, sinaluvchilar guruhida kommunikativ kompetentlikning
tarkibiy komponentlari o‘rtasida ahamiyatli aloqadorlik mavjudligi aniqlandi. Natijalarga asoslanib, tobelik
agressivlik bilan yuqori darajada ahamiyatga ega ekanligi ma’lum bo‘ldi (r=0,18; p≤0,01). Ta’kidlash joizki,
kursantlarda insonlarga nisbatan tobelikning ortib ketishi ularda agressivlikni ham kuchayishiga sabab
bo‘ladi. Ma’lumki, kursantlarda tobelikning ortishi ularda o‘zidan va o‘zgalardan qoniqmaslik hissini yuzaga
keltirishi bilan birga atrofdagilarga nisbatan tajovuzkor munosabatni ham paydo bo‘lishiga olib keladi. Shu
o‘rinda ta’kidlash joizki, agressivlik insonning salbiy xulq-atvoridan bo‘lib vaziyat va sharoitga qarab turli
shakllarda namoyon bo‘ladi.
Metodika bo‘yicha natijalarga e’tibor qaratadigan bo‘lsak, kompenentlik alohida mustaqil hodisa
sifatida namoyon bo‘lishini ko‘rishimiz mumkin. Haqiqatdan ham, kompetentli inson har qanday holatda
ham o‘zini o‘zi boshqarishi, nazorat qilishi hamda salbiy ta’sirlarda himoya qila olishi bilan tavsiflanadi.
Bunday toifaga kirgan shaxslar doimo muloqot va munosabatga kirishishlari jarayonida suhbatdoshning har
bir fikrini qo‘llab-quvvatlashlari, diqqat bilan tinglash ko‘nikmalari shakllanligidan dalolat beradi. Shu bois,
ularda muloqot jarayonida o‘zga insonlarga nisbatan tobelik va agressivlik holatlari kuzatilmasligi tabiiy
hisoblanadi.

ORACLE MA'LUMOTLAR BAZASINI SAQLASH ARXITEKTURASI
Kategoriya: Oracle arxitektura ma'lumotlar bazasining tarkibiy qismlari
Oracle ma'lumotlar bazasini tashkil etadigan fayllar bir nechta turlarni o'z ichiga oladi.
Oracle ma'lumotlar bazasini saqlash arxitekturasini tashkil etuvchi ushbu fayllar quyidagicha tashkil etilgan:
Boshqaruv fayllari : to'g'ridan-to'g'ri ma'lumotlar bazasi to'g'risidagi ma'lumotlarni o'z ichiga oladi (ya'ni ma'lumotlar bazasining fizik tuzilishi to'g'risidagi ma'lumotlar). Ushbu fayllar ma'lumotlar bazasi uchun juda muhimdir. Ularsiz ma'lumotlar bazasi ichidagi ma'lumotlarga kirish uchun ma'lumotlar fayllarini ochib bo'lmaydi.
Ma'lumotlar fayllari : foydalanuvchi yoki ma'lumotlar bazasi ilova ma'lumotlarini, shuningdek metadata va ma'lumotlar lug'atini o'z ichiga oladi
Onlayn operatsiyalar jurnali fayllari : ma'lumotlar bazasi nusxasini tiklashga imkon beradi. Agar ma'lumotlar bazasi serveri ishdan chiqsa, lekin ma'lumotlar fayllarini yo'qotmasa, misol ularni ushbu fayllardagi ma'lumotlar bilan qayta tiklaydi.
Ma'lumotlar bazasi muvaffaqiyatli bo'lishi uchun quyidagi qo'shimcha fayllar muhimdir:
Zaxira fayllari : ma'lumotlar bazasini tiklash uchun ishlatiladi. Odatda, ommaviy axborot vositalarining ishlamay qolishi yoki foydalanuvchi xatosi shikastlanganda yoki asl faylni o'chirib tashlaganida siz zaxira nusxadan faylni tiklaysiz.
Arxivlangan jurnal fayllari : nusxada hosil bo'lgan ma'lumotlarning doimiy o'zgarishi (tiklash ma'lumotlari). Ushbu fayllar va ma'lumotlar bazasini zaxiralash orqali yo'qolgan ma'lumotlar faylini tiklashingiz mumkin. Shunday qilib, arxivlangan jurnallar tiklangan ma'lumotlar fayllarini tiklashga imkon beradi.

" Jismoniy saqlash tuzilmalari "
Mantiqiy saqlash tuzilmalari Oracle Database-ga disk maydonidan foydalanishni nozik boshqarish imkoniyatini beradi.
Ushbu mavzu mantiqiy saqlash tuzilmalarini muhokama qiladi:
Ma'lumotlar bloklari
Ma'lumotlarning eng aniq darajasida Oracle ma'lumotlar bazasi ma'lumotlar bloklarida saqlanadi. Bitta ma'lumotlar bloki diskdagi ma'lum baytlarga mos keladi.
Miqdori
An darajada axborot muayyan turini saqlash uchun foydalaniladigan yagona ajratish olingan mantiqiy qo'shni ma'lumotlar bloklar muayyan soni, deb.
Segmentlar
A segment (masalan, bir stol yoki indeks), bir foydalanuvchi obyekti uchun ajratilgan darajada, bir qator ma'lumotlarni bartaraf yoki vaqtinchalik ma'lumotlar.
Stollar maydoni
Ma'lumotlar bazasi jadval maydonlari deb nomlangan mantiqiy saqlash bloklariga bo'linadi. Bir jadval uchun maydon - bu segment uchun mantiqiy idish. Har bir jadval maydoni kamida bitta ma'lumot faylidan iborat.

" Saqlashning mantiqiy tuzilmalari "
Oracle ma'lumotlar bazasi ma'lumotlar bazasini boshqarish va kirish uchun xotira tuzilmalari va jarayonlaridan foydalanadi. Barcha xotira tuzilmalari RDBMS ni tashkil etuvchi kompyuterlarning asosiy xotirasida mavjud.
Ilovalar Oracle ma'lumotlar bazasiga ulanganda, ular ma'lumotlar bazasi nusxasiga ulanishadi . Masalan, SGA-ga qo'shimcha ravishda boshqa xotira maydonlarini ajratish va fon jarayonlaridan tashqari boshqa jarayonlarni boshlash orqali ilovalarga xizmat ko'rsatadi.

Ko'p tomonlama arxitektura
Oracle Database 12 c- dan boshlab , multitenant arxitektura Oracle ma'lumotlar bazasiga multitenant konteynerlar bazasi (CDB) bo'lishga imkon beradi.
A CDB nol, bir, yoki bir qancha foydalanuvchi tomonidan yaratilgan takılabilir bazalarini o'z ichiga olgan bir jismoniy bazasi hisoblanadi. A takılabilir bazasi (PDB) jadvallarini, diagramma ob'ektlarini ko'chma yig'ish, va nonschema bir uchun paydo e'tiroz Oracle Net bo'lmagan CDB sifatida mijozga. A non-CDB PDBs o'z ichiga olmaydi an'anaviy Oracle ma'lumotlar bazasi hisoblanadi.
Oracle Database 12 c- dan boshlab, CDB yoki CDB bo'lmagan holda ma'lumotlar bazasini yaratishingiz kerak. CDB bo'lmagan CD-ni CD-diskka PDB sifatida ulashingiz mumkin. PDB-ni CDB bo'lmagan joyga ko'chirish uchun siz Oracle Data Pump-dan foydalanishingiz kerak.
Ayrim kompyuterlardagi bir nechta fizik ma'lumotlar bazalarini bitta kompyuterda yagona ma'lumotlar bazasiga birlashtirish orqali, ko'p funktsiyali arxitektura quyidagi afzalliklarni beradi.

Kirish (Introduction). Jahonda oliy ta’limni rivojlantirishda ta’limni individuallashtirish,
kompyuterlashtirish va standartlashtirish kabi umumiy tendensiyalarga e’tibor berilmoqda. Shu bilan birga,
hozirda yangi avlod ta’lim resurslariga, birinchi navbatda, axborot resurslariga alohida e’tibor qaratilmoqda.
Ta’lim haqidagi zamonaviy tushunchada “Ta’lim resurslari” tushunchasi ommalashib bormoqda [1].
Mamlakatimizda 2019-yilning oktyabrida “O‘zbekiston Respublikasi oliy ta’lim tizimini 2030-
yilgacha rivojlantirish konsepsiyasi” qabul qilindi [2]. Konsepsiya mazmuni mamlakatimiz oliy ta’lim
tizimini isloh qilishning ustuvor yo‘nalishlarini aks ettiradi. Unda ta’lim jarayonlarini raqamli texnologiyalar
asosida individuallashtirish, masofaviy ta’lim xizmatlarini rivojlantirish, ta’lim jarayonlarida «bulutli
texnologiyalar»dan foydalanish, milliy elektron ta’lim resurslari yaratilishini jadallashtirish, ta’lim
jarayonida elektron resurslar salmog‘ini bosqichma-bosqich oshirib borish, elektron o‘quv adabiyotlar
yaratish kabi aniq yo‘nalishlar belgilab berilgan.
Shu nuqtayi nazardan, “Amaliy mexanika” umumkasbiy fani laboratoriya mashg‘ulotlarini o‘qitishda
turli elektron ta’lim resurslarini ishlab chiqish zaruriyati mavjudligi maqolaning dolzarbligini belgilab
beradi.
