Bog'liq Ziyovuddin Tarmoq 4-amaliyVTP da server switch nimani anglatadi?
JAVOB
VTP (Virtual Trunking Protocol) tarmoqlarida, "server" switch VLAN ma'lumotlarini o'zgartirishi, yangi VLAN lar yaratishi va mavjud VLAN lar bo'ylab o'zgartirishlar kiritishi mumkin bo'lgan kommutatorlarni anglatadi. VTP server switch, tarmoqda VLAN ma'lumotlarini boshqarishi uchun to'g'ri holda sozlashlar qabul qilishi va ularga javob berishi mumkin bo'lgan kommutatordir. Ular tarmoqda o'zgartirishlarni amalga oshirishi mumkin va o'zgartirishlarini VTP tarmoqi boyicha barcha qurilmalar bilan sinxronlashtirishi mumkin.Boshqalariga VTP ma'lumotlari tarqatilishi va o'zgartirilishi uchun VTP serveri hisoblanadi. Buning uchun, u tarmoqdagi barcha kommutatorlar bilan aloqani ta'minlaydi va ularga VLAN ma'lumotlarini sinchronizatsiya qiladi. Bu jarayonda, server switch tarmoqdagi VLAN ma'lumotlarini boshqaradi va ularni boshqa kommutatorlarga tarqatadi.VTP tarmoqida, odatda bir nechta VTP serverlari bo'lishi mumkin, lekin ularning soni juda kichik tarmoqlarda ham bo'lishi mumkin, masalan, faqat bir VTP server kommutatori mavjud bo'lishi mumkin. Bu server tarmoqda o'zgartirishlarni amalga oshirishi va barcha qurilmalar bilan VTP ma'lumotlarini sinchronlashtirishi uchun mas'ul bo'ladi.
6. VTP da transparent switch nimani anglatadi?
Javob
VTP (Virtual Trunking Protocol) tarmoqlarida, "transparent" switch (o'qishchi kommutator) VLAN ma'lumotlarini yo'qotadi va tarqatmaydi. U tarmoqdagi VLAN ma'lumotlarini boshqarish uchun mas'uliyatni o'ziga olmaydi, hamda ularni o'zgartira olmaydi va sinxronizatsiya qila olmaydi.VTP o'qishchi switch VLAN ma'lumotlarini qabul qiladi, ammo ularni tarmoq bo'ylab tarqatmaydi. Bular VTP paketlarini qabul qiladi, ammo ularni tarmoqda o'zgartirishlar kiritish uchun VTP serveri yoki clienti sifatida faol bo'lmaydi.O'qishchi switchlar, VLAN ma'lumotlarini o'z o'rtasida sinchronizatsiya qilish yo'lni tanimasdan tarmoqdagi VLAN ma'lumotlarini saqlab qoladi. Bu, bir tarmoqda bir nechta VTP domainlari yoki VTP versiyalari mavjud bo'lganda foydalaniladi, yoki VTP ma'lumotlarini xavfsizlik maqsadida to'xtatish uchun.Bundan tashqari, o'qishchi switch VLAN ma'lumotlarini tarmoqga tarqatmasligi uchun juda keng qo'llaniladi. Masalan, o'qishchi switchlar, qurilma qurilmasini saqlab qolgan holda tarmoqga qo'shilishi va VLANlar sozlashlari ko'rsatilishi talab etiladigan xususiyatli tarmoqlarda foydalanilishi mumkin.

Bog'liq Ziyovuddin Tarmoq 4-amaliyQaysi turdagi switch asosiy tashabbuskor hisoblanadi?
Javob
Asosiy tashabbuskor switchlar odatda "server" switchlar hisoblanadi. Ular tarmoqda VLAN ma'lumotlarini o'zgartirishi, yangi VLAN lar yaratishi va mavjud VLAN lar bo'ylab o'zgartirishlar kiritishi mumkin bo'lgan kommutatorlardir. Bu tarmoqda VLAN ma'lumotlarini boshqarish uchun mas'uliyatni o'ziga oladi va boshqalarga VLAN ma'lumotlarini tarqatish va sinchronizatsiya qilish masalalari uchun javobgar bo'ladi.Asosiy tashabbuskor switch, VTP (Virtual Trunking Protocol) tarmoqida VTP server sifatida faol bo'lishi mumkin.

E-Mail
E-mail allows users to send and receive written messages.
Chat Rooms
Chat rooms allow a number of people to “meet” on the Internet. It is similar to having a telephone conversation with a number of people at one time except that the participants type instead of talk.
The Internet is often described as being like a vast city. It is an exciting place with a great variety of places to visit. There are shops, entertainment areas, educational areas and people to meet. But it also contains dangers. There are areas that we do not want to go to and that we certainly would not want children to visit.

Sicherheit von Datenübertragung und Authentisierungsmechanismen

Sicherheit von Datenübertragung und Authentisierungsmechanismen
Generell wird ein Webserver von außen über die HTTP-Schnittstelle angesprochen. Abhängig davon, welches Ziel das Webangebot hat und welche Inhalte und Anwendungen angeboten werden, sind die folgenden Fragen von Bedeutung:
- Muss die Integrität der Daten bei der Übertragung vom Webserver zum Client geschützt werden?
- Muss die Vertraulichkeit der Daten bei der Übertragung vom Webserver zum Client gewährleistet werden?
- Ist eine Authentisierung des Webservers dem Client gegenüber erforderlich?
- Ist eine Authentisierung der Clients gegenüber dem Webserver erforderlich?
Bei einem reinen Informationsangebot, das öffentlich zugänglich sein soll, werden alle diese Fragen normalerweise verneint werden können. Handelt es sich jedoch um ein E-Commerce- oder EGovernment-Angebot, so werden sicherlich mehrere Fragen bejaht.
Im Wesentlichen betreffen diese Fragen nur Eigenschaften der verwendeten Übertragungsprotokolle HTTP oder HTTPS. Spezifisch für den einzelnen Webserver ist dabei nur, inwieweit der Webserver diese Protokolle unterstützt. Diese Punkte können daher als Kriterien für die Auswahl eines Webserver-Produktes herangezogen werden.

Points for Parents to Consider
It is important to promote Internet Safety in the home and to monitor Internet use.
-
Keep the computer in a communal area of the home.
-
Ask children how the computer works.
-
Monitor on-line time and be aware of excessive hours spent on the Internet.
-
Take an interest in what children are doing. Discuss with the children what they are seeing and using on the Internet.
-
Advise children to take care and to use the Internet in a sensible and responsible manner. Know the SMART tips.
-
Discuss the fact that there are websites which are unsuitable.
-
Discuss how children should respond to unsuitable materials or requests.
-
Remind children never to give out personal information on the Internet.
-
Remind children that people on line may not be who they say they are.
-
Be vigilant. Ensure that children do not arrange to meet someone they meet on line.
-
Be aware that children may be using the Internet in places other than in their own home or at school.

Access to the Internet is provided through a filtered service. All access is provided through the NINE Connect service which is designed to filter out unsuitable material.
Supervision
No filtering service is 100% effective, therefore all children’s use of the Internet is supervised by an adult.
Use of the Internet is a planned activity. Aimless surfing is not allowed. Children are taught to use the Internet in response to a need e.g. a question which has arisen from work in class.
Websites are previewed by teachers and revisited to ensure that they are suitable for children’s curriculum needs and ability levels.
Search engines are used selectively. Teachers will choose the search engine and topic and discuss sensible search words which have been tried out beforehand.

How Valuable is the Internet in Education?
The Internet is a unique and exciting resource. It brings the world into the classroom by giving children access to a global network of educational resources.
-
It encourages the development of ICT skills that are vital to life-long learning.
-
It takes learning beyond the classroom.
-
It allows access to stores of information that might otherwise be unavailable in school.
-
It provides up-to-date information.
-
It is a fast and efficient way of communicating and retrieving information.
-
It encourages independent learning.
-
It is part of their life experience. It is “cool”.
The Internet is increasingly forming part of our work, home, social and leisure activities. There is no doubt that the use of the Internet is an essential skill for children as they grow up in the modern world.

What are the Dangers?
The Internet is an open communications channel, available to all. Anyone can send messages, discuss ideas and publish materials with little restriction. This brings young people into contact with people from all sectors of society and with a wide variety of materials some of which could be unsuitable.
Key Concerns are:
Potential Contact
Children may come into contact with someone on-line who may wish to harm them. Some adults use chat rooms or e-mail to communicate with children for inappropriate reasons
Children need to be taught:
-
That people are not always who they say they are.
-
That “Stranger Danger” applies to the people they encounter through the Internet.
-
That they should never give out personal details or
-
That they should never meet alone anyone contacted via the Internet

Children are not given individual web-based e-mail addresses. In some instances children may have access to a group e-mail address to communicate with other children as part of a particular project. Messages sent and received in this way are supervised by the teacher.
Children are taught to be Internet Wise. Children are made aware of Internet Safety Rules and are encouraged to discuss how to cope if they come across inappropriate material.
Points for Teachers to Consider
Internet use should be planned, task orientated and educational within a regulated and managed environment
-
Supervision is the key strategy. Children should have a teacher or classroom assistant present when using the Internet. Computers should be positioned so that it is possible for adults to see materials on screen.
-
Children should know why they are using the Internet. Aimless surfing should never be allowed. Teach children to use the Internet in response to a need. E.g. to answer a question which has arisen from work in class.
-
Search engines require careful use and planning/supervision. Children can be bombarded with information and yet fail to find the material they need. Teachers should select the search engine and topic and discuss sensible search words which have been tried out beforehand.
-
Children do not need thousands of website addresses. A small appropriate choice is much more effective. Favorites is a useful way to present this choice. Sites should always be previewed and revisited to be checked out. Consider off-line viewing
-
Individual e-mail addresses are not considered suitable for children. Class or project e-mail addresses could be used. All incoming and outgoing mail will be checked.
-
Discuss with pupils the rules for responsible Internet use. It is not enough to protect children from materials, we must teach them to become Internet Wise. Children need to learn to recognise and avoid the risks. Children need to know what to do if they come across inappropriate material or if they are approached by a stranger.
-
Be informed – read e.g. - NGfL Superhighway Safety. http://safety.ngfl.gov.uk
-
Discuss Internet Safety with colleagues and as a staff.

Excessive Commercialism
The Internet is a powerful vehicle for advertising. In visiting websites children have easy access to advertising which is very persuasive.
Children should be taught:
-
Not to fill out forms with a lot of personal details.
-
Not to use an adult’s credit card number to order online products.
If children are to use the Internet in places other than at school e.g. – libraries, clubs and at home, they need to be educated about how to behave on-line and to discuss problems.
There are no totally effective solutions to problems of Internet safety. teachers, pupils and parents must be vigilant.

Bog'liq Neft sanoatida gazlar sarflarini avtomatlashtirish 1.1 Neft sanoatida gazlarni sarflar nisbati boshqariladigan obektlar
Neft sanoatida gazlarni sarflar nisbatni nazorat qilish strategiyasi yondirilgan isitgichlar, qozonlar, pechlar va shunga o'xshash yoqilg'i yoqish jarayonlarining xavfsiz va foydali ishlashida asosiy rol o'ynashi mumkin. Buning sababi shundaki, bu jarayonlarning yonish zonasidagi havo-yonilg'i nisbati yoqilg'ining yonish samaradorligi va atrof-muhit emissiyasiga bevosita ta'sir qiladi.
Nisbatni nazoratni amalga oshirish talabi shundaki, yoqilg'i bilan ta'minlanish tezligi ham, yonish havosi tezligi ham o'lchanadi va jarayon o'zgaruvchan (PV) signallari sifatida mavjud. Quyida ko'rsatilgan havo/yonilg'i nisbatini boshqarishning kontseptual strategiyasidir.
Ushbu vakillik arxitekturasida yoqilg'i oqimi tezligi o'choqdan chiqadigan issiqlik tashuvchisi haroratini saqlab turish uchun o'rnatiladi. Boshqa jarayonlarda yoqilg'i oqimi tezligi bug' sarlavhasidagi bosimni, burnerning quyi oqimidagi kanal haroratini yoki samarali ishlashi uchun tartibga solinishi kerak bo'lgan shunga o'xshash o'zgaruvchini ushlab turish uchun sozlanishi mumkin. Keyin yonish havosining oziqlanish tezligi kerakli havo / yoqilg'i nisbatini saqlab turish uchun oqim fraktsiyasi (nisbati) regulyatori tomonidan o'rnatiladi. Yuqorida oddiy sensor va valf ko'rsatilgan bo'lsa-da, biz ushbu munozarada davom etar ekanmiz, biz ushbu kontseptual arxitekturani kengaytiramiz va o'zgartiramiz, chunki:
Yonish havosi oqimi uchun oxirgi boshqaruv elementi (FCE) valf bo'lishdan ko'ra, odatda o'zgaruvchidir. tezlikni puflagich, ehtimol sozlanishi amortizatorlar yoki panjurlar bilan. Yonish havosi oqimi tezligini o'lchash qiyin va yonish gazining chiqindi oqimi yo'lining bir qismida bosimning pasayishini o'lchashni o'z ichiga olishi mumkin. Turli xil ilovalarda havo oqimi tezligi yovvoyi ozuqa bo'lishi mumkin, yoqilg'i oqimi esa boshqariladigan ozuqadir. Stack gaz analizatorlari yonish samaradorligi va atrof-muhit emissiyasi bilan bog'liq bo'lgan kimyoni nazorat qilgani uchun qiymat va murakkablikni oshiradi.

1.3 Gazlar sarfini rostlasda qo'llaniladigan ijro mexanizmlari
Ikki tomonlama ijro mexanizmlar pistonning ikkala tomoniga havo yoki suyuqlik bilan ta'minlanadi, bu esa valfni ishga tushirish uchun zarur bo'lgan harakatga erishadi. Ushbu konfiguratsiya valfni ochish va yopish uchun havo yoki suyuqlik energiyasining pnevmatik yoki gidravlik bosimidan foydalanadi. Prujinali ijro mexanizmlarda havo yoki suyuqlik faqat pistonning bir tomoniga beriladi va mexanizmlarni harakatlantirish uchun energiya qarama-qarshi tomondan bahordan keladi. Ushbu konfiguratsiya valfni ochish yoki yopish uchun havo yoki suyuqlikning pnevmatik yoki gidravlik bosimidan foydalanadi va kamon teskari harakatga ta'sir qiladi. Pnevmatik ijro mexanizmlar ish energiyasini ishlab chiqarish uchun siqilgan havodan foydalanadi. Ushbu ijro mexanizmlar tez javob beradi, lekin yuqori bosim ostidagi muhit uchun ideal emas, chunki gaz siqiladi. Pnevmatik ijro mexanizmlar prujinali va ikki tomonlama ta'sirli dizaynlarda mavjud.
1.5-rasm Pnevmatik (ijro mexanizmi) ijro mexanizm
Piston tipidagi pnevmatik ijro mexanizmlar pistonga ta'sir qiluvchi havo orqali chiziqli kuch hosil qiladi. Ushbu chiziqli kuchni momentga aylantirish (aylanuvchi valflarda foydalanish uchun) maxsus ijro mexanizm konstruktsiyalari bilan amalga oshiriladi. Skotch-bo'yinturuqli ijro mexanizmlarga piston, birlashtiruvchi mil, bo'yinturuq va aylanuvchi pin kiradi. Bo'yinturuq harakatning ikki uchida piston o'qidan 45 ° ga, o'rta harakat holatida esa piston miliga 90 ° ga siljiydi. Eğimli skotch-bo'yinturuq dizayni ofset kapalak valfini ishga tushirish uchun ideal.
Rack-and-pinion ijro mexanizmlari an'anaviy ijro mexanizmlardan farqli o'laroq, 180 ° burilish chiqaradi, ular pinionning 90 ° burilishini hosil qiladi. Ushbu turdagi ijro mexanizm, ayniqsa, vilka klapanlarini ishga tushirish uchun mos keladi. Diafragma uslubidagi ijro mexanizmlar dumaloq po'lat korpusdagi rezina diafragma va stendni o'z ichiga oladi. Ushbu turdagi ijro mexanizm diafragma klapanlari va globus klapanlari kabi qisqaroq harakat talab qiladigan klapanlar uchun idealdir.
