1 Ubiquity of English
2 The ubiquity of the aforementioned is spread in all domains and not mastering this language
3. Things you don’t know about the origins of English
1 Ubiquity of English
Wide spread use of English today is obvious, and the fact of its becoming a global language is inevitable. Presently, it has spread its roots all over the world. In the field of politics, economics and diplomacy English became an essential skill. Hence, students of all directions and specialties are highly interested in language acquisition. The environment itself supports learners, providing them with language bits from all around.
The Internet makes learning process incredibly easier, in ways that were not possible before. It makes it easier to connect with people who speak different languages. An enormous amount of information is processed in English, and more than half the world’s technical and scientific papers are published in English as well.
The widespread use of English has been a great argument. The Chinese government is promoting the teaching of Mandarin in order to establish Chinese as the new international language. Yet the difficulty in means of writing Chinese characters, and the tonal nature of the language, make it unlikely to come out as a preferred language for not native speakers of Chinese. Another case is French. French used to be the language of diplomacy and the preferred language of international exchange. Educated people in Europe, as well as the Americas, Africa, Asia and the Middle East were proud to speak French. However, this is much less so the case today. And subsequently Esperanto is offered up as an alternative. It was offered as a politically neutral international language. It also has been constructed quite rationally and easy to learn, but in the foreseeable future no society is likely to change English as a highly convenient means of international communication to any other language.
The same is about our own country. Wherever you go or whatever you deal with you surely stumble on something in English. Not only in capital Tashkent but in distant regions you can come across English expression. For instance, here in Tashkent even in some areas like Chorsu, Chopon ota or Kukcha where national bias are favored, one may count out lots of English words used in ads, brand names, tabloids and so on. Therefor language acquisition is now less laborious owing to the whole environment contributes its improvement. Also less actual is the argument of lacking due environment, because basic words are mostly known for inveterate housewives as well.

Cellular signal
Depending on your model, ARES will operate on either a 3G or LTE CAT-M1 network. ARES must have decent signal
strength to successfully connect to a nearby cellular tower and communicate with the Fracsun cloud. A site survey is
highly recommended before installation.
5.2.1 Site survey
There are several ways to perform a site survey for the best cellular connectivity. The most
convenient way is to use a smart phone on a AT&T or T-Mobile network. Verizon uses a
different carrier frequency, therefore will not work for performing a site survey. An Android
phone is recommended to perform the site survey if available. Apple devices have a built-in
“Field Test” mode that allows you to see the signal strength, which may or may not work on
certain iPhone versions. Apps on Android devices have many options, like selecting the carrier
frequency (3G or 4G/LTE) and visualizing the signal level on a gauge or a chart.
• Android devices: open the Play Store and download any of the following apps:
o
Network Cell Info Lite by M2Catalyst, LLC.
o
Signal Strength by Lakshman
• Apple devices: Open the call dialer and type in: *3001#12345#* to enter Field Test mode.
o
Go to the “Serving Cell Measurements” page to view the Measured RSSI.
5.2.2 Signal strength
The device’s signal strength is in a “healthy” range when the RSSI is greater than -100 dBm (the closer to 0, the
stronger the signal). The signal quality, which measures relative noise in the connection, should be greater than 35%
(the closer to 100%, the better the quality). Both signal strength and quality impact the health of the connection. For
example, a site survey measuring an RSSI of -92 dBm at 45% quality would be “Fair” for the 3G band and “Good” for
the LTE CAT-M1 band, making it a good candidate for an install location.

SMA antenna connection
A gold-plated SMA RF connector is located on the bottom-side of ARES. The
supplied
cellular di-pole whip blade antenna must be threaded onto the
SMA connector to
send/receive cellular data.
If the antenna is not connected, ARES will not output data or
functional properly.
The antenna is omni-directional with uniform power in all directions. The
optimum
antenna orientation is
straight (not bent)
for highest signal power and quality, as seen
in Figure 8-1.

11.0 Finalizing the installation
Solar is often located in extremely rugged environments, therefore it’s important to “tidy up” the soiling station
before leaving the site. Following these simple steps will protect the equipment from damage and reduce the number
of maintenance events over the life of the soiling station.
11.1 Zip ties and strain relief
Follow these simple tips to protect the station:
• Add zip ties to both ends of the corrugated sheathing – near the
ARES and Wash Extension connections – approximately 3-5” from
the connectors.
• Add strain relief to the corrugated sheathing near the ARES side. Coil
the corrugated sheathing in 1-3 loops and attach to a
rigid structure
using zip ties.
• Do not allow the corrugated sheathing to lay directly on the ground,
as weed abatement tools could cut the tube or cable.
• In environments with grazing sheep or other animals, consider
adding a small fence around the Wash Extension so the
animals
don’t knock it over.
Note: Never over-tighten the
zip ties, as doing so could restrict water flow in the flex tubing.
11.2 Completed installation
The image showcases a completed ARES installation:

Where to install
Measuring soiling is a new area of study for solar asset owners and operations teams. Every solar plant has a unique
soiling profile based on several environmental factors like dominant wind direction, agricultural activity, dirt roads,
mowing operations, pollen, wildfire ash, and air pollution. Knowing where to install soiling measurement stations, like
ARES, is a not a well-studied field and there is no single location that will capture an accurate soiling model of the
entire array. For this reason, it is beneficial to have multiple measurement locations within an array field to capture
non-uniform soiling phenomena and improve statistical significance of the soiling loss data.
The key is to install at locations on the array that are representative of the entire system, or the specific area that you
are studying. The pins in the image below show potential locations of ARES devices across a solar plant.
Figure 5-1: Potential ARES device locations across an entire solar plant.
5.1.1 Uniform or non-uniform soiling
Every site has a unique soiling profile. Often, due to local site conditions, soiling levels throughout a single array can
vary greatly. By creating measurement zones within a single array, the ARES device can empower a team to focus on
areas of highest soiling first.
5.1.2 Placement on the array
To generate a representative soiling loss value, the ARES device must be installed adjacent to the array in the same
tilt and orientation as the modules themselves. This is achieved by attaching the ARES unit to a structural component
of the racking system. This can be a torque tube, Z-purlin, aluminum module rack or any other member that matches
the array tilt. It is ideal to install the ARES hardware while the array is clean to achieve a matching baseline. This can
be achieved after a significant rain even or an array cleaning. If neither of these are possible nor convenient, the
ARES unit can be installed while taking note that the soiling loss measurement will not match. The daily accumulated
soiling loss (soiling rate) can still be used in the Fracsun portal to calculate an estimate of current soiling loss at the
site by extrapolating back to the most recent cleaning event.

6.0 Preparing the ARES device before mounting
6.1.1 Automatic wake in the sun
ARES devices are shipped in a deep-sleep mode state, which preserves the battery for up to 45 days while in the
box. When placed in the sunlight (specifically greater than 250 W/m
2
), ARES will wake from deep-sleep within 15
minutes (sometimes less) and start connecting to the nearest cellular tower. Once
a connection is established, ARES
will begin normal operation.
This feature allows ARES to startup without opening the unit and connecting the internal battery. Just place ARES in
the sun, and it will power up.
6.1.2
Low battery
If more than 45 days has passed, the battery may be in a low-power state. If this occurs, give ARES at
least 20 minutes in full sun (or 40 minutes with clouds) to recharge the battery. Once
the battery is at a
nominal level, ARES will automatically wake (if in the sun) and begin normal operation.

Kompyuterda vektorli tasvirlar bilan ishlash nuqtali tasvirlar bilan ishlashga qaraganda ancha oson. Hozirda vektorli tasvirlar yaratuvchi amaliy dasturlar mashina grafikasining asosini tashkil qiladi.
Fraktal grafika - bu tasvirni chizish yoki jihozlash emas, balki uni matematik hisoblashlarga asoslangan dasturlar asosida qurishdir, ya'ni bunda tasvirlar formulalar yordamida ko'riladi.. Fraktal grafikada esa tasvirlarni matematik hisoblashlar yordamida avtomatik o’zgartirib ko’paytirish yo’li chiroyli manzaralar hosil qilinadi. Fraktal kompozisiya yaratish chizish yoki shakl berish emas, balki dasturlashga asoslanadi. Teleko’rsatuvlar va reklamalarni badiiy bezashda ishlatiladi.
Fraktal grafika odatda o’yin dasturlarini yaratishda ko’proq qo'llaniladi.
Fraktal grafika matematik hisoblashlar asosida tasvirlarni avtomatik yaratish uchun qo'llaniladi. Shuning uchun ham uning asosi sifatida rasm, shakl, tasvir hosil qilishning dasturlash usuli tanlangan.
Bu grafika, odatda, turli jarayonlarni modellashtirish, tahlil qilish, turli qiziqtiruvchi dasturlar yaratishda keng qo'llaniladi.
Kompyuter grafikasining quyidagi turkumlarini ajratib ko'rsatish mumkin:
• tijoratga oid
• namoyishlarga oid;
• injenerlikka oid;
• ilmiy;
• ko'rgazmaviy;
• animatsion;
Tijoratga oid grafika elektron jadvallarda yoki berilganlar bazasidagi axborotlarni aks ettirish uchun xizmat qiladi. Bu axbo-rotlar ShEHM monitor ekranida grafik, gistogramma, diagramma va xohlagan boshqa ko'rinishlarda aks ettirilishi mumkin. Bunda grafiklar matn izohlari va ma 'him joylarda shartli belgili izohlar bilan ta'minlanadi.
Tiiorat grafikasiga tegishli bo'lgan amaliy dasturlar paketi tasvirni ekranda tezda va qulay ifodalashga qaratilgan, chunki tijoratchiningsiy maqsadi axborotlarni qayta ishlash jarayonidagi o'zgarishlarni tezda muhokama qilib, tegishli qarorlar qabul qilishdan iboratdir. Tasavvurni yanada oshirish uchun ushbu paketlarda tasvirni turli xildagi grafika shaklida tasvirlash imkoniyati kiritilgan. Bu esa, o'z navbatida, barcha turdagi tasvirlarni ekranda birgalikda ko'rib, tahlil qilish imkoniyatini oshiradi. Bu paketlarning eng ahamiyatli tomoni shundaki, ular tasvirlarni turli xil shaklda berishdan tashqari aks ettirilgan grafikalarni tahlil qilish imkoniyatini ham beradi. Shu sababli bu paketlarga turli xil matematik tahlil usullari, jumladan statistik tahlil, ehtimollar nazariyasi, iqtisodiy jarayonlar bashorati kabi usullar kiritilganki, ular berilgan axborot to'plamini tahlil qilish

Bog'liq Reja Kompyuter grafigi tushunchasi-fayllar.orgRang modellari.
RGB modelining nomi Red - qizil, Green – yashil va Blue – ko’k birlamchi ranglarning bosh xarflaridan olingan bo’lib, ushbu ranglarning turli proporsiyalarda aralashtirish natijasida ko’rinuvchi spektrning turli hil boshqa ranglarini olish mumkin. Birlamchi ranglarning aralashmasidan ikkilamchi moviy (cyan), pushti (magenta) va sariq (yellow) ranglar xosil bo’ladi.
Rasm. 1.1. RGB modeli.
RGB modelining tashkil etuvchilari 0 dan 255 gacha qiymat qabul qilishlari mumkin. R=255, G=255, B=255 bo’lganda oq rang, R=0, G=0, B=0 bo’lganda esa qora rang xosil qilishimiz mumkin.
CMYK modeli bo’yoqlarning nurni yo’tish qobiliyatiga asoslangan. Oq rangning nur o’tuvchi bo’yoqdan o’tishida spektrning bir qismi yutiladi. Yutilmagan nur qaytadi va odam ko’ziga tushadi.
Rasm. 1.2. CMYK modeli.
Ranglar moviy (Cyan), pushti (Magenta) va sariq (Yellow) ranglar aralashmasidan paydo bo’ladi. Ularning to’liq aralashmasidan qora (blacK) rang xosil bo’ladi. Modelining tashkil etuvchilari 0 dan 100 gacha qiymat qabul qilishlari mumkin.
HSB(HSV) modeli. Model nomi o’nga asos bo’lgan uch komponentning bosh xarflaridan olingan: Hue - rang toni; Saturation - to’yinganlik; Brightness - yorqinlik. Model odam ko’zining rangni xis qilish qobiliyatiga asoslangan.
Rang toni 0 dan 360 gradusgacha diapszondagi burchak kattaligi bilan tavsiflanadi.
To’yinganlik (yoki xromatiklik) rangning tozalik darajasidir. U kul rangning boshqa rangga nisbati bilan aniqlanadi (0% – kul rang, 100% – to’la to’yingan rang).
Rangning yorqinligi 0 dan 100 gacha o’zgarishi mumkin.

Bog'liq Norboyeva Shoxsanam O’quv amaliyotining maqsadi : Talabalarni maktabgacha ta’lim muassasasi hayoti, ta’lim – tarbiyaviy va pedagogik jarayonlar, ota – onalar bilan olib boriladigan ish usul – uslublari va tarbiyachi faoliyati bilan yaqindan tanishtirishdan iborat.
Men nima uchun ekanligini bilaman ta'lim amaliyoti maktabgacha ta'lim muassasasida. Olingan nazariy bilimlarimni tizimlashtirishga, amaliyotda qo‘llashga hissa qo‘shdi.
Ushbu amaliyot tufayli men o'quv jarayonini qurish bo'yicha tahlil qilish va xulosa chiqarishni o'rgandim bolalar bog'chasi.
Men amaliyotga psixologik jihatdan tayyor edim, shuning uchun ham men bolalar bilan muloqot qilish, bolalarni u yoki bu faoliyatga qiziqtirish kabi ko'plab turli ko'nikma va ko'nikmalarni egallashga muvaffaq bo'ldim.
Men ham professional - pedagogik jihatdan mashq qilishga tayyor edim, buni o'quv jarayoniga osonlik bilan jalb qilganimdan dalolat berdi.
Men o'zimga yuklangan vazifalarni hal qilish algoritmini professional tarzda o'zlashtirdim - pedagogik faoliyat.
Men kasbiy-pedagogik faoliyat jarayonida qanday kompetensiyalarni shakllantirganimni bilaman. - Men kasbiy-pedagogik faoliyat jarayonida qanday kompetensiyalarni shakllantirganimni bilaman.
- Amaliyot davomida men maqsadimga erishdim va muammolarni hal qildim.
- Men o‘tkazgan diagnostik tadqiqot ham psixologik, ham pedagogik sifatlarni shakllantirishda katta ahamiyatga ega edi. Bu vazifa oson emas, lekin juda qiziqarli bo‘lib, suhbatlashish qobiliyatimni rivojlantirdi, turli faktlar, hodisalar, shaxsning turli ko‘rinishlarini kuzatish, tahlil qilish, tushuntirishlar berishga o‘rgatdi.
LOREM IPSUM DOLOR SIT AMET, CONSECTETUER ADIPISCING ELIT. MAECENAS PORTTITOR CONGUE MASSA LOREM IPSUM DOLOR SIT AMET, CONSECTETUER ADIPISCING ELIT. MAECENAS PORTTITOR CONGUE MASSA
Diagnostik tadqiqot tufayli men quyidagilarga erishdim:
- - umumiy psixologik qonuniyatlarni aniqlash, tahlil qilish va hisobga olish qobiliyatini rivojlantirish;
- - bolalarda paydo bo'ladigan pedagogik aralashuvni talab qiladigan muammolarni payqash va tahlil qilish qobiliyatini rivojlantirish.
Katta yoshdagi maktabgacha yoshdagi bolalarning kognitiv oltingugurtini tashxislash uchun men beixtiyor xotira, o'z-o'zini nazorat qilish, e'tibor va idrok etishning rivojlanish darajasini aniqlash usullarini tanladim. Menimcha, bolalarning kognitiv oltingugurtning ushbu tarkibiy qismlari ushbu yosh toifasi uchun asosiy hisoblanadi. Chunki ular boshqa komponentlarning rivojlanishidagi kamchiliklarni qoplashlari mumkin.
Masalan, xotira va e'tiborning rivojlanishi fikrlash faol rivojlana boshlaydi.
Amaliyot natijalarini o'z-o'zini tahlil qilish va amaliyot rahbari, maktabgacha ta'lim muassasasi xodimlari tomonidan mening ishimni ekspert baholashi mos keladi.
Umuman olganda, men qo'yilgan vazifalarni bajardim va "a'lo" bahoga loyiqman deb ayta olaman.
Спасибо за внимание!

1. MBBTning nazariy asoslari 1.1 Asosiy tushunchalar, komponеntlar va modеllar
Informatsion tizimlarni yaratish bo’yicha jadal harakatlar ma'lumotlar hajmining tеz suratlar bilan oshib borishi sharoitida 60 yillar boshida maxsus “Ma'lumotlar bazasini boshqarish tizimi” (MBBT) dab ataluvchi dasturiy komplеksning yaratilishiga olib kеldi.
MBBT asosiy xususiyatlari - bu protsеduralar tarkibi bo’lib, ular faqat ma'lumotlarni kiritish va saqlashda ishlatilmasdan, ularning strukturasini ham tasvirlaydi. Ma'lumotlarni o’zida saqlab va MBBT ostida boshqariladigan fayl, oldin ma'lumotlar banki dеb atalib, kеyinchalik esa “Ma'lumotlar bazasii” dab yuritila bosladi.
Ma'lumotlarni boshqarish tizimi, quyidagi xossalarga ega:
fayllar to’plami mantiqiy kеlishuvni quvvatlaydi;
ma'lumotlar ustida ish yuritish tili bilan ta'minlaydi;
har xil to’xtalishlardan kеyin ma'lumotlarni qayta tiklaydi;
MBBT bir nеcha foydaloanuvchilarning parallеl ishlashini ta'minlaydi.
MBBT funktsiyalari tarkibiga yanada aniqroq qilib quyidagilar qabul qilingan:
Tashqi xotirada bеvosita ma'lumotlarni boshqarish.
Bu funktsiya MBga bеvosita kiruvchi ma'lumotlarni saqlash uchun kеrakli strukturani ta'minlab tashqi xotiraga qo’shadi. MBBT ishlatishda mavjud fayl tizimi imkoniyatlari aktiv ravishda ishlatiladi. Rivojlantirilgan MBBTda foydalanuvchi istalgan holda MBBT fayl tizimini ishlatayapdimi bu haqda bilishi shart emas, va agar ishlatsa, u holda fayllar tashkil qilingan bo’ladi. Xususiy holda MBga bеrkitilgan ob'еktlarni MBBT quvvatlaydi.

1-mavzu: Ma’lumotlar bazasi, ularning turlari Reja: Asosiy tushunchalarBog'liq 1-mavzu. Ma’lumotlar bazasi, ularning turlari Reja Asosiy tushuMB tillarini quvvatlash
Ma'lumotlar bazasi bilan ishlashda ma'lumotlar bazasi tili dеb ataluvchi maxsus til
ishlatiladi. Zamonaviy MBBT MB bilan ishlash uchun barcha kеrakli vositalarni
yagona birlashgan til qo’llab quvvatlaydi. Hozirgi kunda rеlyatsion MBBT uchun
kеng tarqalgan standart til - bu SQL (Structured Query Language) tilidir.
o
SQL tili rеlyatsion MB sxеmasini aniqlaydi va ma'lumotlar ustida
(manipulyatsiya) ish yuritadi. Unda MB ob'еkti nomlariga (rеlyatsion MB uchun –
jadval nomi va uning ustunlari) o’zgartirishlar kiritish SQL tili kompilyatori
yordamida amalga oshiriladi. Bundan tashqari uning ichki idеntifikatorlariga
o’zgartirishlar kiritishni ham amalga oshiradi. MBBT ning ichki qismi (yadrosi)
jadval nomlari va uning ustunlari bilan umuman ishlamaydi.
o
SQL tili o’z ichiga MB butunlik chеgarasini aniqlashning maxsus vositasini
oladi. MBning butunligini tеkshirishni ta'minlaydi. MBni modifikatsiya qilish
uchun kompilyatsiya vaqtida SQL kompilyatori mos dasturiy kodni gеnеratsiya
qiladi.
o
SQL tilining maxsus opеratorlari MB «ko’rinish»lari dеb ataladigan
jadvallarni aniqlashga imkon bеradi. Bu «ko’rinish»lar MB da nomlangan
ustunlardan iborat so’rovlar shaklida saklanadi (rеlyatsion MB ga nisbatan
ixtiyoriy so’rovning natijasi jadval bo’ladi). Foydalanuvchi uchun «ko’rinish»,
xuddi MB saqlanadigan ixtiyoriy bazaviy jadvaldеk, jadvaldir, lеkin «ko’rinish»lar
yordamida konkrеt foydalanuvchi uchun MB ko’rinishini chеgaralash yoki
kеngaytirish mumkin. «Ko’rinish»larni ko’llash SQL tili darajasida ham amalga
oshiriladi.
o
MB obеktiga avtorizatsiya ruxsati SQL tilining maxsus oprеatorlar to’plami
yordamida amalga oshiriladi.
o
MB ob'еktlariga ostuplar SQL opеratorlarining maxsus tuplami asosida
yaratiladi. Bu еrdagi goya, xar xil foydalanuvchilar turli polnomochiyalarga ega
bulishi kеrak. MB sining jadvalini yaratgan foydalanuvchi, shu jadval bilan ishlash
polnomochiyalarini tulik tuplamiga ega. Bu tuplamga boshka foydalanuvchilarga
barcha yoki ba'zi polnomochiyalarni bеrish xam kiradi, xudi shunday
polnomochiyalarni bеrish polnomochiyasi xisobga olgan xolda. Foydalanuvchi
polnomochiyalari maxsus jadval-kataloglarda yozilgan buladi va ularning kontroli
SQL tili darajasida xam amalga oshiriladi.

Et kompas kan hjælpe med at finde vej. Kompasset kan fortælle dig retningen mod jordens nordpol. Ved at holde en fast kompaskurs kan du bevæge dig i en lige linje. Det er en god ting at kunne, hvis du skal navigere. Du kan nemt lave dit eget kompas. Et kompas består af en magnet, som kan bevæge sig frit og rette sig ind efter Jordens magnetfelt.
Stærk magnet
Lille flamingo- eller træplade, omkring 7 gange 7 cm (skær evt. en lille plade ud af en stor flamingoplade)
Skål eller balje med vand - så stor, at flamingopladen kan dreje rundt nede i den
Stor synål
Sådan gør du
Fyld skålen eller baljen med vand.
Synålen skal magnetiseres ved at stryge den hen over magneten.
Læg synålen på pladen.
Læg pladen ned i skålen med vand.
Pladen vil nu lægge sig sådan, at synålen peger mod nord-syd.

19-amaliy ish. MS Excel dasturida ma’lumotlar bilan ishlash.
Ishning maqsadi: Excel dasturida ma’lumotlar bilan ishlash ko’nikmasini oshirish.
Kerakli asbob va jihozlar: komyuter, kompyuterning asosiy qurilmalari
Nazariy qism: Excel dasтurida ma’lumotlar bilan ishlash
Microsoft EXCEL dasturida matnlar — bu raqamlar, bo’sh joylar va boshqa belgilardan iborat bo’lgan ixtiyoriy ketma-ketlikdir. Kiritilayotgan ma’lumotlarimiz yacheykaga sig’magan holda sig’may qolgan qismi ekran yachey-kasining o’ng qismiga o’tkaziladi (agar u bo’sh bo’lsa). Bunday hollarda quyidagi usullardan foydalanib, yacheyka kengligi va balandligini o’zgartirish mumkin. Bir necha so’zdan iborat va yacheykaga sig’magan matnni ko’rish uchun «Format Yacheyki» (Yacheyka bichimi) buyruqlarini tanlash
va bayroqcha (flajok) belgisini «perenosit po slovam» degan ibora ustiga joylashtirish kerak. Yacheykada yangi satrni boshlash uchun ALT+ Yenter tugmalarini bosish kerak.
Ustun kengligini o’zgartirish. Bir yoki bir nechta ustun kengligini o’zgartirish usullarini qarab chiqamiz. Buning uchun o’zgartirish kerak bo’lgan ustunlarni belgilab olish kerak, Ular bir xil uzunlikdagi yacheykalar bo’lishi lozim.
• Sichqoncha ko’rsatkichini ustunning o’ng chegara chizig’iga olib kelib, ustun kengligini keraklicha uzaytirish. Bu ish sichqoncha tugmasi bosilgan holatda amalga oshiriladi.
• «Format»—«Stolbets» (Ustun) — «Shirina» (Kenglik) buyruklarini ketma-ket tartib bilan tanlab, «Shirina stolbsov» (Ustun kengligi) muloqot oynasida parametrga kerakli qiymat beriladi va OK tugmasi bosiladi.
• «Format»—«Stolbets» (Ustun) — «Avtopodbor shirinы» (Kenglikni avtomatik tanlash) buyrug’ini bajarish.
Bunda ajratib ko’rsatilgan ustun kengligi shunday tanlanadiki, unga eng uzun ma’lumotlar qatorini kiritish mumkin bo’ladi.
Ustunning’ o’ng chegarasiga sichqoncha ko’rsatkichini olib kelib, sichqonchaning chap tugmasi ikki marta tez-tez bosilsa, kiritilayotgan qatorning eng uzun ma’lumoti sig’adigan ustun kengligi avtomatik ravishda tanlanadi.
