TEMPERAMENT VA UNING TURLARI. (TEMPERAMENTNI
O‘RGANISH METODLARI)
Tevarak - atrofimizdagi hayot faktlari va hodisalarga bir
xil odamlar tez va engillik
bilan, bir xillari shoshmasdan va qiyinchilik bilan, boshqalari esa
sust va befarq
bo`ladilar, yana bir xillari keskin va g`ayratli, ayrimlari esa bir xil maromda va
mulohazali bo`ladilar. Temperament va xarakter odamning ijtimoiy
munosabatlarida yaqqol namoyon bo`ladigan individual xususiyatlardir.
Temperament - lotincha “aralashma” yoki qismlarning nisbati, degan ma`noni
bildiradi. Temperament - shaxsning hissiy qo`zg`aluvchanligi va umumiy
harakatchanligi bilan sifatlanadigan individual xususiyatlar yig`indisi.
Temperament - inson faoliyatida uning asab tizimi tipining namoyon bo`lishi.
Temperament his -tuyg`ularning paydo bo`lish tezligi va
kuchida hamda kishining
umumiy harakatchanligida namoyon bo`ladigan individual - psixologik
xususiyatlarining majmuidir. Temperamentga taalluqli individual dinamik
xususiyatlarning asosiy belgilari:
1) temperamentning ayni bir xil xususiyatlari, xuddi bir odamning o`zida
faoliyatning har xil turlarida va har turli maqsadlarda namoyon bo`ladi;
2) temperamentning xususiyatlari odam hayotining butun davomida va ma`lum bir
qismida barqaror va o`zgarmasdir;
3) mazkur odamdagi temperamentning turli xususiyatlari
bir - biri bilan tasodifiy
birlashgan bo`lmay, balki bir - biri bilan qonuniy bog`langan bo`lib, bu xususiyatlar
temperament tiplarini ifodalovchi muhim tuzilmani hosil qiladi.
Temperamentning
xususiyatlari deganda
, bir inson
psixik faoliyati tezligini
belgilovchi psixikaning barqaror individual xususiyatlarini tushunamiz. Bu
xususiyatlar turli mazmundagi faoliyatlarda, motivlarda
va maqsadlarda nisbatan
o`zgarmaydi, hamda temperament tipini ifodalovchi tuzilmani tashqil qiladi.
Natija:
Bular bilim uchun yangi bilimga intiladigan nazariy mutafakkirlardir,
ularning
"ilmiy tomiri" ularni nafaqat dunyo muammolari,
balki prozaik, kundalik hayotiy
vaziyatlarga nisbatan ko'proq yoki kamroq asosli
tushunchalarni yaratishga
undaydi. Ushbu turdagi odamlar rejalashtirilgan niyatlar va harakatlarni o'zlarining
farazlarini sinab ko'rish uchun o'ziga xos tajriba sifatida ko'rishadi. Ularning
nostandart, axloqiy va axloqiy jihatdan xavfli xatti-harakatlarga moyilligi shu erdan
kelib chiqadi. Intuitiv-mantiqiy tipdagi odamlar tashqi mezonlarga unchalik e'tibor
bermaydilar, muloqotda ko'pincha yashirin va sovuq, o'zini yuqori baholaydi, lekin
beqaror, o'ziga juda ishonadi, kamdan-kam hollarda etuk emotsionallik bilan ajralib
turadi, nazariy jihatdan o'rganish qobiliyati odatda o'rtachadan yuqori. Ular umumiy
aholining atigi 10% ni tashkil qiladi.

Temperamentni aniqlash uchun qanday testlar mavjud?

1. Harakatlar va tanqidiy ko'nikmalar: Temperament, insonning harakatlarini,
tanqidiy ko'nikmalarni va faoliyatini shakllantiradi. Masalan, sanguviniklar ko'proq
jiddiy, optimistik va faol bo'lib, melanxoliklar esa o'zlarini qisqa qolib, tushunchar
va go'zallikni qidiradilar.
2. Komunikatsiya shakllari: Har bir temperament turi o'z
turli komunikatsiya
shakllarini tanlayadi. Masalan, sanguviniklar ko'proq sodda va aloqaqa bo'lishadi,
melancholiklar esa tushunishlilar, tafsilotchi va ma'naviyatga qiziqarli bo'lishadi.
3. O'z-o'zini tushunish va boshqarish: Temperament insonning o'z-o'zini
tushunishini va boshqarishini ta'sir qiladi. Masalan, koleriklar bo'proq haddbuzar va
boshqaruvchi bo'lishadi, phlegmatiklar esa odob-ahvol va samimiy bo'lib, o'z-o'zini
boshqarishga tayyorlashadi.
4. Stressga qarshi turish: Temperament insonning stress bilan muloqot qilish va
uning ustiga qanday reaksiya ko'rsatishini ta'sir qiladi. Ba'zi
insonlar stress bilan
yaxshi boshqaradilar, ammo boshqalar esa juda negativ o'zgartirishlar ko'rsatishlari
mumkin.
5. Barcha harakatlar sohasidagi o'zgartirishlar: Temperamentning kuchli ta'siri
o'zgaruvchan harakatlar, ko'nikmalar va faoliyatlar bilan bog'liqdir. Bu esa o'z turli
masalalarga qarshi turgan har bir insonni boshqa o'zgaruvchanliklarni o'rganish va
qabul qilishga olib keladi.
Insonning temperamenti individual xususiyatlari bilan bog'liq bo'lib, bu
xususiyatlarni tushunish va boshqarish uning shaxsiy hayoti, ishlari, va aloqalari
ustida katta ta'sir qiladi.
4
. Temperamentning inson o'zini boshqalarga qarshi o'zgartirishi mumkinmi?
Ha, temperament inson o'zini boshqalarga qarshi o'zgartirishi mumkin.
Insonning
temperamenti uning o'zgarib bo'lishini va o'zini boshqalarga qarshi o'zgartirishini
ta'sir qiladi.
About Windows Server 2003 SP1 - Windows Server 2003 R2 Reviewer's Guide Microsoft Windows Server 2003 R2

About Windows Server 2003 SP1
Windows Server 2003 SP1 provides convenient, comprehensive access to the latest updates, enhancements, and new features for Windows Server 2003. Each of these components allows customers to better leverage the enhanced security, reliability, and performance of Windows Server 2003.
Updates
Update management is one of the great challenges of computer security. Despite the inherent management difficulties they present, updates will continue to play a vital role in better securing enterprise IT. While enhancements and new functionality delivered by Windows Server 2003 SP1 make great strides toward more proactive security, reacting to known threats is still a core mission of SP1.
Frequent updating is essential to keeping up with exploits as they are discovered. By providing these updates together in SP1, Microsoft provides customers, both new and old, with the latest protection for Windows Server 2003.
The updates disseminated by SP1 cover some of the most basic functionality—and thus remove some of the most widely exploited attack points—of Windows Server 2003. These updates include:

Enhancements
In addition to finding and updating security holes before hackers can exploit them, SP1 includes improvements to functionality that originally shipped with Windows Server 2003. Such enhancements make a great product better and raise the security, reliability, and productivity of Windows Server 2003. Below are brief descriptions of some of these key enhancements:
Stronger defaults and privilege reduction on services—Services such as RPC and DCOM are integral to Windows Server 2003, but they are also an alluring target for hackers. By requiring greater authentication for RPC and DCOM calls, SP1 establishes a minimum threshold of security for all applications that use these services, even if they possess little or no security themselves.
Support for “no execute” hardware—SP1 allows Windows Server 2003 to utilize functionality built in to computing hardware to help ensure that malicious code cannot launch attacks from areas of computer memory that should have no code running in it. For both 32-bit and 64-bit systems, this enhancement closes the door on one of the broadest and most exploited avenues of information attack.
Network Access Quarantine Control components included—Windows Server 2003 SP1 now includes the Rqs.exe and Rqc.exe components to make deployment of Network Access Quarantine Control easier.
IIS 6.0 metabase auditing—The metabase is the XML-based, hierarchical store of configuration information for Internet Information Services (IIS) 6.0. The ability to audit this store allows network administrators to see which user accessed the metabase in case it becomes corrupted.

With Windows Server 2003 R2 Enterprise Edition, each software license allows you to run, at any one time, one instance of the server software in a physical operating system environment and up to four instances of the server software in virtual operating system environments. These new use rights enable customers to save costs by using virtualization to consolidate their servers. In order to run the additional instances in a virtual operating system environment, you must also license virtualization software, such as Microsoft Virtual Server 2005. The licensing change, allowing up to four instances, is specific to Windows Server 2003 R2 Enterprise Edition. For the Standard Edition of Windows Server 2003 R2, you may only run one instance in either the physical or virtual environment. For the Datacenter Edition of Windows Server 2003 R2, in addition to running one instance of the software in a physical operating system environment per hardware partition on a licensed server, you may run one instance of the software in a virtual operating system environment per licensed processor on that server. For more detailed information on the license terms for Windows Server R2, check the following resources on this page. For licensing questions on the Datacenter Edition of Windows Server, contact your OEM that licenses Datacenter Edition with your server hardware.

To help accommodate the widely varying storage management capabilities found throughout the IT industry, Windows Server 2003 R2 includes new tools designed to provide 1) a centralized view of storage; 2) simplified storage planning, provisioning and maintenance; and 3) improved monitoring and reporting. These benefits are captured in convenient new tools that enable administrators to more efficiently manage storage across IT resources and optimize storage space on those resources. Storage management extends to two key new features contained in Windows Server 2003 R2:
File Server Resource Manager – File Server Resource Manager (FSRM) enables system administrators to understand how storage is being used and to manage the use of their storage by generating storage reports, applying quotas to volumes and folders, and screening files on the server. Using FSRM you can better plan and optimize storage by creating quotas, creating file screens, and scheduling storage reports.
Storage Manager for SANs – Storage Manager for SANs enables customers to provision storage on one or more storage subsystems on a storage area network (SAN). Based on Microsoft Virtual Disk Service (VDS) technology, Storage Manager for SANs allows provisioning on Fibre Channel and Internet SCSI (iSCSI) storage subsystems.

Additional Features - Windows Server 2003 R2 Reviewer's Guide Microsoft Windows Server 2003 R2

Additional Features Web Services for Management
Windows Remote Management Service is Microsoft’s implementation of the new Web Services for Management protocol and allows organizations to use a secure and firewall-friendly remote management protocol.
Web Services for Management include the following benefits:
Allows organization to use a secure and firewall friendly remote management protocol.
Enables cross-firewall remote management of servers using WMI via HTTP and SOAP.
Enables management of remote servers when the operating system is not running in a pre-boot and post-crash scenario such as a change boot order or power-cycle.
Hardware management makes Window Server aware of IPMI instrumentation in the motherboard with a new driver in the following scenarios:
Events raised in the hardware system event log are also displayed in he Windows event log.
Sensor values and probes can be read and set through a new WMI provider such as status of fan speed and temperature.
Allows IPMI to be accessible to all management tools and scripts that use WMI.
Subsystem for UNIX-based Applications
Subsystem for UNIX-based Applications (SUA) is a source-compatibility subsystem for compiling and running custom UNIX-based applications on a computer running a Windows server-class operating system. Administrators can perfect their applications in SUA with little or no change to their original source code.
Subsystem for UNIX-based Applications provides an operating system for POSIX processes. SUA, along with its package of support utilities (such as shells and a Telnet client) available for download on the Microsoft Beta website, provides a complete UNIX environment. The download package includes a comprehensive set of scripting utilities and a software development kit (SDK) designed to fully support the development capabilities of SUA while providing a complete UNIX-based application development experience.
SUA also supports case-sensitive file names, job control, compilation tools, and the use of over 300 UNIX commands, utilities, and shell scripts. Because the subsystem installs separately from the Windows kernel, it offers true UNIX functionality without any emulation.
New features in this release include:

Microsoft Internet Explorer—Updates to this software help prevent unintentional downloads of misrepresented, malicious code and the automatic resizing of browser windows as a ruse to extract sensitive data from employees.
Microsoft Outlook® Express—This update affords users the option of rendering e-mail in plain text rather than HTML. This provides one more barrier against the spread of malicious code through e-mail.
WebDAV Redirector—By updating this behind-the-scenes program, customers can access Web-based Distributed Authoring Versioning (WebDAV) servers, such as Microsoft Windows SharePoint® Services and MSN® Communities, as if they were standard file servers. Moreover, this update helps prevent customers’ credentials (user name, password) from being transmitted over unencrypted channels during such exchanges.
Microsoft addresses update-related server down time with the Hot Patching feature in SP 1. Hot Patching allows customers to apply updates to drivers, DLLs, APIs, or any non-kernel-level component of Windows Server 2003 without restarting the server.

ASP.NET 2.0
ASP.NET 2.0 reduces development and management costs of Web applications with improvements that simplify management, enable high performance solutions, and empower developers.
Efficiently managing ASP.NET 2.0 Web sites and applications is simpler. A new configuration API allows administrators to write scripts that automate provisioning, deployment, and management. Additionally, a new MMC plug-in integrated with IIS 6.0 enables GUI-based administration of all ASP.NET configuration settings giving the user with integrated set of management tools for IIS and ASP.NET administration. With the Health Monitoring API, developers can add granular event-level analysis functionality to their applications which enables real-time tracing and stats of running applications.
ASP.NET 2.0 introduces a number of new features for implementing high performance solutions. First, Web Sites can now be pre-compiled to enhance performance and responsiveness or to protect intellectual property by deploying with source code stripped away. Second, ASP.NET 2.0 offers features like an enhanced logging framework and built-in automated security and database caching which allow developers to build self-managing, self-healing applications on the DSI (Dynamic Systems Initiative) model. Lastly, ASP.NET 2.0 can be customized for any enterprise environment by replacing or extending any of the built-in features or services.
New ASP.NET services and built-in features enable more productive development of richer application scenarios. Forty five new Security, Data, Navigation & Web Part Controls allow developers to write up to 70% less code for faster development of rich web sites and applications. Security is enhanced and streamlined by Membership and Login APIs adding custom authentication and authorization to new applications. Additionally, a new page design framework using Master Pages, Themes, and Skins separates site design from code and content to deliver a consistent, customizable user experience that can be updated and maintained separately from the application’s code and content.

Listni polosalarga qirqish

13.6- rasm. Listni bichish sxemasi: a- bo’ylama; b- ko’ndalang.
Listdan olinadigan buyumlar soni to’liq polosalar sonini polosadan olinadigan to’liq
buyumlar soniga ko’paytirish bilan topiladi, ya’ni :
𝑵 = 𝒏 ∙ 𝒏′
Listni ko’ndalang bichish (13.7 rasm
b). Bu yerda listdan
olinadigan polosalar soni
𝒎 =
𝑳
𝑩
ga teng.
Polosadagi buyumlar soni soni esa:
𝒎′ =
𝑳
𝟏
−𝒌
𝟏
𝑨
(13.3)
Listni bichishni tanlash afzal bo’ladi, chunki bunday holda polosani qirqish unumdorligi
yuqoriroq bo’ladi. Bundan tashqari, polosa uzun bo’lganda (bo’ylamasiga bichishda) materialni
shtampga joylashtirish kamroq bo’ladi, pressni kamroq yoqib-o’chirishga to’g’ri keladi. Biroq η
katta bo’lganda ko’ndalang bichish ko’proq foydali va tejamli bo’lib chiqishi mumkin. Listni
bichish turini tanlash berilgan holda qaysi omil (unumdorlik yoki chiqindilarning miqdori) ko’proq
ahamiyat kasb etishiga bog’liq bo’ladi.
Oksidlanish-qaytarilish reaksiyalari

[ ]
Oksidlanish-
qaytarilish
reaksiyalari
Oksidlanish-qaytarilish reaksiyalari —
elektronlarning atomlardan atomlarga
butunlay yoki qisman oʻtishi bilan bogʻliq
kimyoviy reaksiyalar. Elektronlar
chiqarilishi oksidlanish, elektronlar
biriktirib olinishi qaytarilish deyiladi. O.-
q.r. atamalari dastlab metall
oksidlarining hosil boʻlish va parchalanish
reaksiyalarida qoʻllaniladi. Cu+’/2O2=CuO
metallarning oksidlanishiga,
CuO+H2=Cu+H2O metall oksidlaridan
metall hosil boʻlishi (qaytarilishi)ga misol
boʻladi.
Atom yoki ionlari reaksiya jarayonida
elektron biriktirib oladigan moddalar
oksidlovchilar,elektron beradigan
moddalar esa qaytaruvchilar deb
ataladi.Oksidlovchi reaksiya vaqtida
oksidlanadigan moddadan elektronni
tortib olib,oʻzi qaytariladi,qaytaruvchi esa
elektronlar yoʻqotib, oʻzi oksidlanadi. Har
qanday oksidlanish qaytarilishsiz boʻla
olmaydi, chunki kimyoviy reaksiyada
atomlar oksidlanish dara-jasi (p)ning
yigʻindisi doimiydir. N2+S12=2NS1
reaksiyasida p (N) 0 dan + 1 gacha
oʻzgaradi, binobarin, vodorod (N)
oksidlanadi; p(S1) 0 dan — 1 gacha
oʻzgaradi, binobarin, xlor S1 qaytariladi.
O.-q. jarayoni keng tarqalgan kimyoviy
reaksiyalar jumlasiga kiradi, uning
tabiatda va texnikada ahamiyati katta.
Barcha turdagi yoqilgʻilarning yonishi, turli
metallarning rudalardan ajratib olinishi O.-
q.r. jarayoniga asoslangan. Metallarning
korroziyaga uchrashi, koʻpgina muhim
kimyoviy mahsulotlarning hosil boʻlishi
ularning oksidlanishi tufaylidir. Elektr-
kimyo sanoati O.-q.r.ga asoslangan. Mis,
nikel, oltin, rux va boshqa eritmalardan
elektrolitik qaytarilish yoʻli bilan olinadi
yoki tozalanadi. Kimyoviy tok manbalari
— akkumulyatorlar va galvanik elementlar
O.-q.r. tufayli ishlaydi va h.k.

Bog'liq Oxunjon tizimlar ma\'ruzaProtsessor arxitekturalari (Fon Neyman arxitekturasi, Garvard arxitekturasi)
Garvard Arxitekturasi
Garvard arxitekturasi bu dasturning ma'lumotlari va ko'rsatmalari mustaqil ravishda hal qilinishi mumkin bo'lgan xotiraning alohida katakchalarida joylashgan kompyuterning konfiguratsiyasi. Ya'ni, bu ikkita alohida sohani o'z ichiga olgan kompyuter tizimi uchun ishlatiladigan atama: buyruqlar yoki ko'rsatmalar va ma'lumotlar uchun. Shu sababli, ushbu arxitekturaning asosiy vazifasi ma'lumotni jismoniy ajratilgan holda saqlash, ko'rsatmalar va ma'lumotlar uchun turli xil signal yo'llarini ta'minlashdir.
Dasturlar xotirasi CSEG (ingl. Code Segment) va ma’lumotlar xotirasi DSEG (ingl. Data Segment) o’zaro ajratilgan hamda har biri o’zining manzilli bo’shlig’i va kirish usullariga ega bo’lgan tarzda yaratilgan tuzilish Garvard arxitekturasi deb ataladi (shunday arxitekturani yaratish taklifini kiritgan Garvard Universiteti laboratoriyasining nomi berilgan). Ushbu arxitektura nisbatan murakkab bo’lib, qo’shimcha boshqaruv signallarini talab qiladi. Biroq, u axborot bilan ancha uddaburon harakatlar bajarish, ixcham kodlashtiriladigan mashina komandalari to’plamini joriy etish va qator hollarda mikroprotsessor ishini jadallashtirish imkonini beradi.
Intel firmasining MCS-51 oilasiga mansub mikrokontrollerlar mulohaza yuritilayotgan arxitekturalarning bir vakili sanaladi. Biroq, u axborot bilan ancha uddaburon harakatlar bajarish, ixcham kodlashtiriladigan mashina komandalari to’plamini joriy etish va qator hollarda mikroprotsessor ishini jadallashtirish imkonini beradi. Intel firmasining MCS-51 oilasiga mansub mikrokontrollerlar mulohaza yuritilayotgan arxitekturalarning bir vakili sanaladi.Bugungi kunda aralash arxitekturali protsessorlar ishlab chiqarilmoqda, ularda CSEG va DSEG yagona manzilli bo’shliqqa joylangan bo’ladi, ammo ular turli murojaat mexanizmlariga ega. Bunga aniq misol tariqasida Intel firmasining 80x86 oilasiga mansub protsessorlarni keltirish mumkin.
Garvard arxitekturasi dastur va ma'lumotlar uchun turli xil xotira manzil maydonlariga ega. Buning natijasida sxemani loyihalash qobiliyati paydo bo'ladi, shunda boshqaruv sxemasi yordamida dastur xotirasidan ma'lumot oqimini boshqarish uchun va ma'lumotlar xotirasiga ma'lumot oqimini boshqarish uchun foydalanilishi mumkin. Masalan, ushbu arxitekturaning sodda versiyasida dasturni tiklash bo'limi dastur ketma-ketligidagi navbatdagi ko'rsatmalarni olish bilan band bo'lishi va parallel ravishda oldingi dastur ko'rsatmasining bir qismi bo'lishi mumkin bo'lgan ma'lumotlarni uzatish operatsiyasini bajarish bilan band bo'lishi mumkin. Ushbu darajada Garvard arxitekturasi bazi cheklovga ega, chunki odatda dastur kodini ma'lumotlar xotirasiga joylashtirish va u yerdan bajarish mumkin emas.

With Windows Server 2003 R2, Microsoft has introduced a number of licensing changes to better facilitate virtualization. To begin with, a single license for Windows Server 2003 R2 Enterprise Edition grants the organization that holds it a license to that physical instance of the operating system as well as licenses for four virtual instances of either Windows Server 2003 R2 Standard Edition or Enterprise Edition. Moreover, Windows Server 2003 R2 licenses only apply to running instances of the operating system; an organization with a library virtual machines with Windows Server 2003 R2 installed on them would not pay for a license of for each installed instance (as with the traditional licensing model), rather, the customer would pay for only those instances of Windows Server 2003 R2 that were running at any given time. Thus not only does this new licensing model provide excellent value with Windows Server 2003 R2 Enterprise Edition, it also nurtures the adoption of virtualization by only making organizations pay for what they use.
