Bog'liq X. K. Aripov, A. M. Abdullaev, N. B. AlimovaIMS komponentasi deb uning diskret element funksiyasini bajaradigan, lekin avvaliga mustaqil mahsulot kabi montaj qilinadigan qismiga aytiladi.
Asosiy IMS konstruktiv belgilaridan biri bo‘lib asos turi hisoblanadi. Bu belgiga ko‘ra IMSlar ikki turga bo‘linadi: yarim o‘tkazgichli va dielektrik.
Asos sifatida yarim o‘tkazgichli materiallar orasida kremniy va galliy arsenidi keng qo‘llaniladi. IMSning barcha elementlari yoki elementlarning bir qismi yarim o‘tkazgichli monokristall plastina ko‘rinishida asos ichida joylashadi.
Dielektrik asosli IMSlarda elementlar uning sirtida joylashadi. Yarim o‘tkazgich asosli mikrosxemalarning asosiy afzalligi – elmentlarning juda katta integratsiya darajasi hisoblanadi, lekin uning nominal parametrlari diapazoni juda cheklangan bo‘lib ular bir - biridan izolyatsiyalanishni talab qiladi. Dielektrik asosli mikrosxemalarning afzalligi – elementlarning juda yaxshi izolyatsiyasi, ularning xossalarining barqarorligi, hamda elementlar turi va elektr parametrlari tanlovining kengligi.
7.2. Pardali va gibrid mikrosxemalar
Pardali IS – bu dielektrik asos sirtiga surtilgan elementlari parda ko‘rinishida bajarilgan mikrosxema. Pardalar past bosimda turli materiallardan yupqa paradalar ko‘rinishida cho‘kmalar hosil qilish yo‘li bilan olinadi.
Parda hosil qilish usuli va unga bog‘liq bo‘lgan qalinligiga ko‘ra yupqa pardali IS (parda qalinligi 1 – 2 mkmgacha) va qalin pardali IS (parda qalinligi 10 – 20 mkm gacha va katta) larga bo‘linadi.
Hozirgi kunda barqaror pardali diodlar va tranzistorlar mavjud emas, shu sababli pardali ISlar faqat passiv elementlar (rezistorlar, kondensatorlar va x.z.) dan tashkil topadi.
Gibrid IS (yoki GIS) – bu pardali passiv elementlar bilan diskret aktiv elementlar kombinatsiyasidan tashkil topgan, yagona dielektrik asosda joylashgan mikrosxema. Diskret komponentlarni osma elementlar deb atashadi. Qobiqsiz yoki mikrominiatyur metall qobiqli mikrosxemalar gibrid IMSlar uchun aktiv elementlar bo‘lib hisoblanadilar.
Gibrid integral mikrosxemalarning asosiy afzalligi: nisbatan qisqa ishlab chiqish vaqtida analog va raqamli mikrosxemalarning keng turlarini yaratish imkoniyati; keng nomentkaluturaga ega bo‘lgan passiv elementlar hosil qilish imkoniyati; MDYa – asboblar, diodli va tranzistorli matritsalar va yuqori yaroqli mikrosxemalar chiqishi.

Synchronous Versus Asynchronous Processing
In Windows 2000, Group Policy application is synchronous by default. There is no logon screen until computer policy is applied and no desktop until user policy is applied.
You can change to asynchronous (via policy), but this can cause unpredictable side effects.
If You Can’t Manage Group Policy
There are several issues to check if you cannot manage Group Policy including:
Required permissions for Group Policy Snap-in.
Delegating control of Group Policy.
Consistency/Performance problems: Where are GPOs managed?

Investigating Core Failures
To investigate these errors:
Turn on Userenv logging or turn on verbose event logging, as explained in the previous section.
View history of applied policies: HKLM or HKCU\Software\Microsoft\Windows\CurrentVersion\GroupPolicy\History\{extension GUID}.
Client Side Extension (CSE) Processing Failures
These types of failures are limited in scope to a single extension failure. Depending on the extension, failures may be limited to failure of a specific policy. These are typically logged in the Event Log under the extension source name.

|
Required Permissions for Group Policy Snap-in
|
bet | 37/50 | Sana | 22.07.2021 | Hajmi | 296 Kb. | | #15617 |
Required Permissions for Group Policy Snap-in
To have policy applied, you must have Read and Apply Group Policy permissions. To use the Group Policy Editor snap-in, you must have Read and Write permissions.
Note: Domain administrators are covered for all Active Directory-based GPOs and local administrators are covered for local GPOs.
Creating a Site GPO
To create a site GPO, use the Active Directory Sites and Services snap-in. Note: You must be a member of Enterprise Administrators.
Delegating Control of Group Policy
If organizational unit administrators have trouble managing Group Policy, check the following permissions:
Manage Group Policy Links.
Create GPO.
Edit GPO.
Manage Group Policy Links
This permission is required for an organizational unit administrator to link a GPO created by another administrator. It is assigned using the “Manage Group Policy Links” in the delegation wizard. This permission:
Allows a user to add, remove, and reprioritize linked GPOs.
Does not allow user to create or edit GPOs.
Actually grants read/write access to GPLink and GPOptions properties of SDOU.
To verify existing permissions, from the Active Directory Users and Computers snap-in:
From the menu bar, click View, then click Advanced Features.
Right click on the desired container and select Properties.
Select the Security tab. You can now view and edit the ACEs on that container.
|
| |
Resolving Replication Problems

To check the status of each GPO on each domain controller, use the Group Policy Verification Tool as explained earlier in this paper.
If the Group Policy container is not synchronized, use Active Directory Replication Monitor (as explained earlier) to force synchronization.
If the Group Policy template is not synchronized, troubleshoot file replication by placing a file in SYSVOL.
If an SDOU is linked to a GPO in another domain, access to the GPO is via a trust.
If the trust fails, access to the GPO fails, and so does Group Policy processing in its entirety. Prevent this scenario by having multiple domain controllers per domain, or by creating explicit trusts.
|
GUID for Group Policy Extensions

To locate the GUID for each Group Policy extension look under:
HKLM\Software\Microsoft\WindowsNT\CurrentVersion\WinLogon\GPExtensions
Some examples of the GUID for Group Policy extensions that ship with Windows 2000:
Application Management.{C6DC5466-785A-11D2-84D0-00C04FB169F7}
Folder Redirection.{25537BA6-77A8-11D2-9B6C-0000F8080861}
IP Security.{E437BC1C-AA7D-11D2-A382-00C04F991E27}
Scripts. {42B5FAAE-6536-11D2-AE5A-0000F87571E3}
Security. {827D319E-6EAC-11D2-A4EA-00C04F79F83A}
Once you have confirmed that policy did not fail due to a Group Policy core error, examine the extensions.
Use the Userenv log to find out:
If the extension failed or ran successfully.
If an extension saw any changes to policy.
If policy was applied to a site, the log can identify the site the computer belongs to.
For individual extensions, see the detailed information below.
|
Did You Move the User or Computer Object?

Did You Move the User or Computer Object?
Client computers cache the directory service location for 30 minutes. When user or computer objects are moved from one organizational unit to another, the client may not “know” right away.
If policy refreshes before the client’s cached directory service location is refreshed, the new policies will not be applied.
Note: If you move a computer to a new container or put it in a new group, you should reboot the computer to make sure the change takes effect immediately.
If you move a user to a new container or put it in a new group, you should logoff and back on to ensure the change takes effect immediately.

Security CSE - White Paper Abstract

Error info can be found in the Event Log. See entries with the source SceCli.
To create a detailed log file for the Security Extension use the following registry key:
HKLM\Software\Microsoft\WindowsNT\CurrentVersion\CurrentVersion\Winlogon\GpExtensions\{827d319e-6eac-11d2-a4ea-00c04f79f83a}\
Set ExtensionDebugLevel = REG_DWORD 0x2
Note: The log file can be found at: %windir%\security\logs\winlogon.log
Scripts processing contains two steps:
Group Policy script processing processes a policy and stores the script information in the registry (for Windows 2000 this is the directory where the scripts.ini file is stored as a hidden file):
HKCU\Software\Policies\Microsoft\Windows\System\Scripts (User Scripts)
HKLM\Software\Policies\Microsoft\Windows\System\Scripts (Machine Scripts)
Script is run via a Userinit process. (Hung scripts timeout in 10 minutes by default)
Note: The timeout is the time allotment for all scripts to run. This can be modified using the Computer policy setting: “Maximum wait time for Group Policy Scripts.”
Common script errors include:
Bad script path.
Hung script.
Access to script is restricted via ACLs (usually for startup/shutdown scripts which run as machine, not user).
Failure of individual scripts may be limited to the individual scripts and not impact the total script processing.
To investigate, check the Application Event Log for entries with Userinit as the source.
|
Administrative Templates CSE

Typical errors include:
Missing or corrupted ntuser.pol file.
Missing or corrupted registry.pol file.
Unable to read policy information from the SYSVOL.
Failure in individual registry policies will cause all registry processing to fail.
To investigate:
Turn on Userenv log or verbose event logging.
Folder redirection processing contains five steps:
Determine which folders to redirect based on changes to policy at logon time.
Determine desired redirected location and verify access.
If folder does not exist: create folders, set access control lists (ACLs).
If folder exists, check ACLs and ownership.
If desired, move contents.
Best practice: Let system create folders and set ACLs for you.
Folder redirection failures only affect the folder redirection extension on a per-folder basis.
If you’re not following the best practice as noted above, typical errors include:
Redirecting to a folder that is incorrectly ACL’d.
User is not the owner of the folder.
Destination does not exist.
To investigate:
Turn on fdeploy logging to verify policy was processed.
Error info can also be found in the Event Log. See entries with the source name folder redirection.
To create a detailed log file for folder redirection use the following registry key:
HKLM\Software\Microsoft\Windows NT\CurrentVersion\Diagnostics
Set: FdeployDebugLevel = Reg_DWORD 0x0f
Note: The log file can be found at: %windir%\debug\usermode\fdeploy.log

Are You Migrating from Windows NT 4.0?

Are You Migrating from Windows NT 4.0?
If the client computer is running Windows 2000 Professional, and if the computer and user accounts both belong to Windows NT 4.0-based domains you should continue to receive system policy. If the domain is Windows 2000, the computer/user will only receive Group Policy.
If the user account is in Active Directory and the computer account is in Windows NT 4.0, then the computer gets system policy and the user gets Group Policy—and vice-versa.
In addition, if you are planning on using sites, a site which is determined by which IP subnet a machine is in, Group Policy will only get defined if the machine is running Windows 2000 in a Windows 2000 domain with Active Directory.
Note: The local GPO processes regardless of the configuration. For details about how Group Policy is applied with various configurations, see Table 2 below. If your computer/user account is in a Windows 2000 domain that cannot be reached (for example, you are logging on with cached credentials), then all Group Policy processing, including the local GPO, will not be processed.

Resolving Group Policy Inheritance Conflicts
To resolve inheritance conflicts, start the search at the top of the Active Directory tree and check:
The order of precedence for each site, domain, or organizational unit (SDOU).
Any user or computer conflicts.
Settings for No Override or Block Policy Inheritance.
Note: No Override wins over Block Policy Inheritance. You can use the GPResult tool or the FAZAM tool, as explained earlier, to help determine order of precedence.
Resolving Group Policy Security/Permissions Issues
To resolve permissions issues, check the following:
Group Policy filtering.
Read and apply Group Policy access control entries (ACEs).
Deny ACEs.
Security group membership.
Disabled GPOs
Check the properties of the GPO and confirm that the user and/or computer portion have not been disabled.
Check the Group Policy links and make sure they are not disabled.

O‘zbekiston Respublikasida dasturiy mahsulotlar bozorini shakllantirish borasida bir qator amaliy ishlar olib borilmoqda. Toshkent davlat iqtisodiyot universiteti «Informatika, menejment va iqtisodiy ta’lim pedagogikasi» fakulteti qoshidagi «Yosh tadqiqotchi olimlar markazi»da «Iqtisodiy informatika» fanidan akademik S.S.G‘ulomovning umumiy tahriri ostida elektron darslik yaratildi. Ushbu darslikning bosh menyusi 1.28-rasmda keltirilgan.
Elektron darslik yo‘naltiruvchi (navigatsion) tizim bilan ta’minlandi. Ushbu tizim foydalanuvchilarga elektron darslikning istalgan betiga to‘g‘ridan-to‘g‘ri o‘tishini ta’minlaydi, bunda butun matnni boshdan – oyoq ko‘zdan kechirishning hojati yo‘q. Har bir mav-zudan keyin test savollari berilgan va foydalanuvchi o‘z bilim darajasini ushbu testlar orqali tekshirsa bo‘ladi. Multimedia vositalari orqali foydalanuvchilar bilan interaktiv aloqa o‘rnatalishi mumkin. Elektron darslik har xil dasturlash tillari orqali tuziladi, lekin hozircha dasturlashning ma’lum bir standarti mavjud emas. Har bir elektron darslik o‘ziga xos bo‘ladi. Ushbu darslikning ham bir necha qulayliklari mavjud, jumladan:

Dastlabki bosqich
Dastlabki bosqichda multimedia – texnologiya asosida ishlab chiqilishi kerak bo‘lgan kursni tanlash kerak bo‘ladi. Bu eng ma’suliyatli bosqichlardan biri sanaladi. Avvalambor, bu sohadagi mavjud kurslarni tahlil qilish kerak. Ushbu kursni ishlab chiqish sarf-harajatlar miqdori hisoblanib chiqilib, uni qancha kengay-tirish va qanday auditoriyaga mo‘ljallangani belgilab olinadi. Kompyuterlarda o‘qitish kurslari maktabgacha bo‘lgan yoshlar, maktab o‘quvchilari, kasb – hunar kollejlari va oliygohlar talabalari va malaka oshirish maskanlari tinglovchilari uchun mo‘ljallangan bo‘lishi mumkin. Shulardan kelib chiqqan holda kompyuterda o‘qitish tizimlarining murakkablik darajalari aniqdanadi.

Tayyorlash bosqichi - Toshkent davlat iqtisodiyot universiteti

Tayyorlash bosqichi
Ushbu bosqichda kompioterda o‘qitish tizimining matni, unda qo‘lla-niladigan rasm jadval va animatsiyalar tanlab olinadi. Amaliyot shuni ko‘r-satmoqdaki, bunday tizimlarni yaratishda matnni oldin chop etilgan darslik yoki o‘quv qo‘llanmalariga asoslanib tanlash kerak ekan, chunki bunda imlo xatolar yo‘q matnning mazmuni ham ancha yuqori saviyada bo‘ladi.
Kompyuterda o‘qitish tizimining matnini shakllantirishda quyidagi bosqichlarga rioya qilish maqsadga muvofiqdir:
maqsadni aniqlash va matnlar manbalarini tanlab olish;
o‘quv matnining tarkibini aniqlash;
dastlabki manbalarni kompyuterda o‘qitish tizimining mundarijasi-dan kelib chiqib tarkiblashtirish;
tarkibiy tahrir qilib chiqish;
nazorat;
matnni ekspertiza qilish.
Asosiy bosqich
Kompyuterda o‘qitish tizimini yaratishning asosiy bosqichida tez-tez ishlatiladigan animatsiya elementlari, ovoz kabilar ishlab chiqiladi. Buni quyidagilar bilan izohlash mumkin. Birinchidan, matnning yonida biror bir illyustratsiyaning bo‘lishi uni qabul qilish darajasini yuksaltiradi. Ikkin-chidan, illyustratsiya qilinayotgan rasm animatsiya yoki videofragmentga nisbatan ko‘p xotirani egallamaydi.
Multimedia muhitida o‘qitish tizimlarini yaratishda animatsiyalardan foydalanish katta o‘rin tutadi. Animatsiyadan o‘quvchiga o‘quv mate-rialining mazmunini to‘liq yetkazish va ayrim ob’ektlarni ichki holatlarini ko‘rsatib berishda samarali foydalanish mumkin. Animatsiyalarni ishlab chiqishda kompyuter grafikasi vositalaridan keng foydalanilib, unda ikki (2D) va uch o‘lchamli (3D) fazoda ob’ektlar taqdim etiladi.
O‘quv jarayonida kompyuterda o‘qitish tizimlaridan foydalanishda video elementlari ham keng qo‘llaniladi, chunki video orqali dunyoning mavjud ob’ektlarini to‘liq aks ettirish mumkindir. Bundan tashqari amali-yotda o‘quv kurslariga ovoz va musiqaviy elementlar ham kiritilmoqda. Bu ham o‘quv materiallarini o‘quvchining xotirasida uzoq muddatda saqlanib qolishida katta o‘rin tutadi.
Axborot-kommunikatsiyalar texnologiyalarining ta’lim sohasida keng ko‘lamda qo‘llanilishi, avvalambor ta’lim tizimi sifati, ilmiy-texnikaviy axborotlarning tezkor olinishi, zamonaviy peda-gogik texnologiyalarning joriy qilinishi va masofaviy o‘qitish tizimini shakllantirishni ta’minlab beradi (1.16 – jadval).

1.28-rasm. “Iqtisodiy informatika” elektron darsligining bosh menyusi
o‘rganilishi kerak bo‘lgan materiallarni talabalarga qulay ko‘rinishda taqdim etish;
elektron darslikning talaba bilan interaktiv usulda muloqotda bo‘la olishi;
talabalarning o‘quv materiallarini mustaqil ravishda o‘rganishi va olgan bilimlarini test sinovlari asosida sinab ko‘rish imkoniyati (1.29-rasm).
1.29-rasm. Elektron darslikda test topshirish tizimining qo‘llanilishi.
Ushbu elektron darslikda navigatsiya tizimidan tashqari translitera-tsiya (boshqa tilga o‘girish) tizimi ham ishlab chikdlgan. Transliteratsiya – kirill alifbosidan lotin yozuviga o‘tishini ta’minlaydi. Har bir betda transliteratsiya tugmachasi mavjud. Shu tugmachani bosgandan keyingi betdagi matn lotin yozuviga avtomatik ravishda o‘giriladi. Ushbu darslik yaratilgan tizim asosida boshqa mavzudagi elektron darsliklarni yaratish mumkin, chunki ushbu tizim juda ham keng qamrovli, universal hisoblanadi.
Elektron darslikni yaratishda kelajakda ayrim muammolarni yechish lozimligi ayon bo‘ldi. Shulardan asosiysi, bu – o‘zbek kirill alifbosidagi «q», «g‘», «o‘», «h» harflarini to‘g‘ridan-to‘g‘ri matnga kiritishdir. Bundan tashqari, texnikamiz hozirchalik mavjud bo‘l-magani sabab «tirik video» elementlarini elektron darslikka kirita olmadik. Tajribamiz shuni ko‘rsat-moqdaki, elektron darslikni oldin biror bir nashriyotda chop etilgan darslik asosida yaratish lozim, chunki, foydalanilayotgan materiallarni tahrir qilish talab etilmaydi va ulardan skaner orqali foydalanish mumkin bo‘ladi. Shu-ning uchun ham, ushbu elektron darslikni yaratishda «Iqtisodiy informatika» («O‘zbekiston» nashriyoti, 1999) va «Axborot tizimlari va texnologiyalari» («Sharq» nashriyoti, 2000) darsliklaridan keng foydalanildi.

CSMA / CA protokollari - Tarmoq xavfsizligi fanidan mustaqil ish

CSMA / CA protokollari. CSMA / CA vaqtni ajratish yoki ommaviy axborot vositalariga
kirish so'rovini yuborish kabi sxemalardan foydalanadi. Vaqtni kesishdan foydalanganda,
har bir stantsiya ma'lumotni faqat ushbu stantsiya uchun qat'iy belgilangan vaqtda uzatishi
mumkin. Bunday holda, tarmoq vaqt bo'laklarini boshqarish mexanizmini joriy qilishi
kerak. Tarmoqqa ulangan har bir yangi stansiya o'zining tashqi ko'rinishi haqida e'lon qiladi
va shu bilan axborot uzatish uchun vaqt bo'laklarini qayta taqsimlash jarayonini boshlaydi.
Etkazish muhitiga kirishni markazlashtirilgan nazoratdan foydalanganda, har bir stansiya
nazorat qilish stantsiyasiga yuboriladigan maxsus uzatish so'rovini yaratadi. Markaziy
stansiya barcha tarmoq ob'ektlari uchun uzatish muhitiga kirishni tartibga soladi.
CSMA / CA ga misol sifatida Apple Computer -ning LocalTalk protokoli keltirilgan.
Poyga asoslangan tizimlar nisbatan kam foydalanuvchilarga ega bo'lgan tarmoqlarda
(katta hajmli fayllarni uzatish) tez harakatlanish uchun eng mos keladi.
Markerlarni uzatish tizimlari. Token o'tish tizimlarida kichik ramka (token) ma'lum
tartibda bir qurilmadan boshqasiga o'tkaziladi. Token - ommaviy axborot vositalarini
vaqtincha boshqarishni tokenga ega bo'lgan qurilmaga o'tkazadigan maxsus xabar. Token
transferi tarmoq qurilmalari o'rtasida kirishni boshqarishni taqsimlaydi.
Har bir qurilma tokenni qaysi qurilmadan olganini va uni qaysi qurilmaga yuborishi
kerakligini biladi. Odatda, bu qurilmalar token egasining eng yaqin qo'shnilari hisoblanadi.
Har bir qurilma vaqti -vaqti bilan tokenni boshqaradi, o'z harakatlarini bajaradi (ma'lumot
uzatadi) va keyin tokenni keyingi qurilmaga o'tkazadi. Protokollar har bir qurilma
tomonidan tokenni nazorat qilish vaqtini cheklaydi.
Bir nechta tokenlarni uzatish protokollari mavjud. IEEE 802.4 Token Bus va IEEE 802.5
Token Ring belgilaridan foydalanishda ishlatiladigan ikkita tarmoq standarti. Token Bus
token-pass kirish nazorati va jismoniy yoki mantiqiy avtobus topologiyasidan foydalanadi,
Token Ring esa tokenli kirishni boshqarish va jismoniy yoki mantiqiy halqa
topologiyasidan foydalanadi.
Raqamli audio yoki video ma'lumotlari kabi vaqtga bog'liq bo'lgan ustuvor trafik mavjud
bo'lganda yoki foydalanuvchilar juda ko'p bo'lsa, tokenli tarmoqlardan foydalanish kerak.

Tarmoq xavfsizligi fanidan mustaqil ishBog'liq tarmoq xavfsizlik lll4) transport qatlami(transport) - nomidan ko'rinib turibdiki, bu aniq ma'lumotni qabul
qiluvchiga etkazib berish va yuborish uchun kerak. Bizning sabr-toqatli pochtamiz bilan
taqqoslaganda, IP-manzil-bu etkazib berish yoki qabul qilish manzili, transport protokoli-
bu xatni o'qishni biladigan va etkazib berishni biladigan pochtachi. Turli maqsadlar uchun
turli xil protokollar mavjud, lekin ular bir xil ma'noga ega - etkazib berish.
Transport qatlami - bu oxirgi, tarmoq muhandislari va tizim ma'murlari uchun katta
qiziqish. Agar quyi darajadagi barcha 4 daraja kerakli darajada ishlagan bo'lsa, lekin
ma'lumotlar belgilangan joyga etib bormagan bo'lsa, muammoni ma'lum bir
kompyuterning dasturiy ta'minotida izlash kerak. Yuqori darajadagi protokollar
dasturchilarni va ba'zida tizim ma'murlarini juda xavotirga soladi (agar u serverga texnik
xizmat ko'rsatsa). Shuning uchun, men bu darajalarning maqsadini o'tmishda tasvirlab
beraman. Bundan tashqari, agar siz vaziyatga xolis qarasangiz, ko'pincha, amalda, OSI
modelining bir necha yuqori qatlamlarining funktsiyalari bitta dastur yoki xizmat
tomonidan qabul qilinadi va uni qaerga tayinlashni aniq aytish mumkin emas.
5) sessiya(sessiya) - ma'lumotlarni uzatish seansining ochilishi va yopilishini boshqaradi,
kirish huquqlarini tekshiradi, uzatish boshlanishi va oxiri sinxronizatsiyasini nazorat qiladi.
Masalan, agar siz faylni Internetdan yuklab olsangiz, u holda sizning brauzeringiz (yoki u
erdan yuklab olganingiz orqali) fayl joylashgan serverga so'rov yuboradi. Bu vaqtda, faylni
muvaffaqiyatli yuklanishini ta'minlaydigan sessiya protokollari yoqiladi, shundan so'ng,
nazariy jihatdan, variantlar mavjud bo'lsa -da, ular avtomatik ravishda o'chiriladi.
6) ijrochi(taqdimot) - ma'lumotlarni oxirgi ilovaga qayta ishlashga tayyorlaydi. Masalan,
agar bu matnli fayl bo'lsa, siz kodlashni tekshirishingiz kerak ("kryakozyabrov"
ishlamasligi uchun), uni arxivdan ochish mumkin .... lekin bu erda siz yana bir bor aniq
ko'rishingiz mumkin. Men ilgari nima yozgan bo'lsam - vakil qayerda tugaydi va keyingisi
qaerda boshlanadi, ajratish juda qiyin:

Bog'liq 8-sinf Informatika fanidan dars ishlanmalarHTML-hujjat – ―html‖ yoki ―htm‖ kengaytmali matnli fayl bo‗lib, u oddiy matn muharririda teglar qo‗llab yozilgan matn. HTML-hujjat va teglari orasida yozilgan bo‗ladi. HTML-hujjat xotiraga yuklansa, u ekranda web-brauzer yordamida web-sahifa ko‗rinishida aks etadi.
HTML-hujjat, odatda, ikkita bo‗limdan iborat bo‗ladi. Birinchisi HEAD (ing. bosh qism yoki sarlavha) bo‗limi bo‗lib u va teglari orasida joylashadi. Ikkinchi BODY (tana) bo‗limi hujjatni mazmuni aks etadi va u va juft teglarini yozish tavsiya etiladi, lekin majburiy emas.
Web-sahifaga kiritilishi lozim bo‗lgan yana bir element – web-sahifa nomi bo‗lib, nom kiritish uchun juft tegi qo‗llaniladi. Web-sahifada bu teg bir marta ishlatiladi. Web-sahifa nomi web-brauzerning sarlavha satrida aks etib, web-sahifaning ichida ko‗rinmaydi. Shu sababli uni web- sahifaning istalgan joyiga yozish mumkin. Web-sahifaga istalgan nom, masalan, o‗z ismingizni berishingiz mumkin.
HTML tili muttasil rivojlanib bormoqda. O‗z navbatida web-brauzerlar ham yangilanib turibdi. Hozirgi kunda web-sahifa tayyorlash uchun asosan HTML-4 tilidan foydalaniladi. Uning ba‘zi buyruqlarini ―eski‖ web-brauzerlar (Internet Explorer-3, Internet Explorer-4) bajara olmaydi. M‘alumki, turli web-brauzerlar, masalan, Internet Explorer va Netscape ham bir biridan farq qiladi. Shu sababli bitta HTML-hujjat turli web-brauzerlarda biror farq bilan aks etishi mumkin.
Eng sodda web-sahifa faqat matndan iborat bo‗ladi. Biz ham web-sahifa tayyorlashni matn joylashtirishdan boshlaymiz. Buning uchun Windowsning Bloknot matn muharririni ishga tushiramiz (boshqa matn muharriridan foydalansa ham bo‗ladi). Web-sahifa, odatda, matnlar kabi sarlavhadan boshlanadi. Bu bizning birinchi web-sahifamiz bo‗lgani uchun, unga ―Bu mening birinchi web- sahifam‖ – deb, sarlavha yozamiz. Buning uchun Bloknot dasturining ishchi maydoniga rasmdagi matn kiritiladi.
Bu matnda , , , , ,

Rasmning kengaytmasi, odatda, web-sahifaga yuklanishi tez bo‘lishi uchun JPEG yoki GIF formatiga mos bo‘lishi kerak, ammo BMP formatli rasm ham ishlatilishi mumkin. Bu haqida keyingi darslarda ma‘lumot beriladi.
