...Exploring the Motherboard and Busses Exploring the Motherboard and Busses The motherboard represents the logical foundation of the computer. Everything that makes a computer must be attached to the motherboard. Answer the following questions: 1. What are the major components of the motherboard? Provide a brief description of each component. 1. Processor (CPU): The processor is the brain of the computer and is the chip where all the computing is done. 2. Memory: This is where the computer stores information while it is working on it. 3. Chipset: The chipset is a link between the processor and the outside world, and handles things like controlling the hard drives, the USB ports, the keyboard and mouse, generates the sounds the computer makes, and sometimes even creates the pictures you see on the screen. 4. Expansion Slots: Expansion slots are connectors that allow you to attach additional cards on the computer, such as video cards, sound cards, modems, and add abilities to the computer that the motherboard doesn’t provide. 5. I/O (Inputs/ Outputs): These are a set of connectors that allows you to connect various devices to the computer, such as the keyboard, monitor, mouse, hard drives, flash drives, printers, and connect the computer to a network. 2. Upgrading only the motherboard will give some performance improvement to a computer system. Why? Upgrading the motherboard will definitely give performance improvement to any computer system...

...Oscar Martinez NT 1110 Lab 4 Task 1: LGA 1156, also known as Socket H[2][3] or H1, is an Intel desktop CPU socket. LGA stands for land grid array. Its incompatible successor is LGA 1155. LGA 1156, along with LGA 1366, were designed to replace LGA 775. Whereas LGA 775 processors connect to a northbridge using the Front Side Bus, LGA 1156 processors integrate the features traditionally located on a northbridge on the processor itself. The LGA 1156 socket allows the following connections to be made from the processor to the rest of the system: PCI-Express 2.0 ×16 for communication with a graphics card. Some processors allow this connection to be divided into two ×8 lanes to connect two graphics cards. Some motherboard manufacturers use Nvidia's NF200 chip to allow even more graphics cards to be used. DMI for communication with the Platform Controller Hub (PCH). This consists of a PCI-Express 2.0 ×4 connection. FDI for communication with the PCH. This consists of two DisplayPort connections. Two memory channels for communication with DDR3 SDRAM. The clock speed of the memory that is supported will depend on the processor. LGA 1156 socket and processors were discontinued sometime in 2012, along with LGA 1366.[4] Supported processors Code name | Brand name | Model (list) | Frequency | Cores/Threads | Max...

...CHAPTER 1 INTRODUCTION TO INFORMATION TECHNOLOGY 1.1 Introduction Modern civilization has become so complicated and sophisticated that to survive one has to be competitive. This compels people to keep themselves informed of all types of happening in the society. And this in turn entails the need for an infrastructure of information. This is the point where information technology or IT becomes most important, as it is the infrastructure that allows us to get information accurately and in time. Before we define information technology, it is important to understand the notion of Data, Information, Technology, and Knowledge. In everyday conversation, people use the terms data and information interchangeably. However, some computer professional make a distinction between the two terms. Data It is the words, numbers, letters, symbol, sound, video and graphics that describe people, events, things and ideas. It is raw facts about people, objects, and events that have little or no meaning. It is the raw material used to create useful information. It becomes information when you use it as the basis for initiating some action or for making a decision. Information It is defined as the words, numbers, letters, symbol, sound, video and graphics used as the basis for human action or decisions. It is data that have been processed and presented in a form suitable for human interpretation, often with the purpose of revealing trends or patterns that can be used in decision-making. It is data...

...INFORMATION TECHNOLOGY FOUNDATION 1 Compiled By: RONKY F. DOH (aka: ronky biggy diggy daddy igp) FU DAME TALS OF COMPUTERS We are living in an information age dependent upon digital information. Digital information is electronic information, the result of computer processing. Every type of job relies upon getting information, using it, managing it, and relaying information to others. Computers enable the efficient processing and storage of information. Do not think of a computer merely as the machine with the keyboard and the mouse, although that might be true for some types of computers. Embedded computers may be inside your household appliances, the video cassette recorder, the automobile, planes, trains, power plants, water purification plants, calculators, and even inside a few toys. These embedded computers are very small. They affect our lives each day. Why, even modern traffic lights operate with computers. They are all around us. Think of additional ways in which computers affect our lives each day. Every organization somehow use(s) a computer to run the organization. Some of the places are hospitals, schools, fire department, banks, stores or supermarkets, stock exchange, police department, insurance companies, transport companies, and government agencies etc. What is a computer? A computer is many things to many people, depending on what it is being used for. At one time the computer can be a machine which processes the payroll, then it can be a machine which tabulates...

...Acknowledgments ix Acknowledgments This book owes a great deal to the mental energy of several generations of scholars. As an undergraduate at the University of Cape Town, Francis Wilson made me aware of the importance of migrant labour and Robin Hallett inspired me, and a generation of students, to study the African past. At the School of Oriental and African Studies in London I was fortunate enough to have David Birmingham as a thesis supervisor. I hope that some of his knowledge and understanding of Lusophone Africa has found its way into this book. I owe an equal debt to Shula Marks who, over the years, has provided me with criticism and inspiration. In the United States I learnt a great deal from ]eanne Penvenne, Marcia Wright and, especially, Leroy Vail. In Switzerland I benefitted from the friendship and assistance of Laurent Monier of the IUED in Geneva, Francois Iecquier of the University of Lausanne and Mariette Ouwerhand of the dépurtement évangélrlyue (the former Swiss Mission). In South Africa, Patricia Davison of the South African Museum introduced me to material culture and made me aware of the richness of difference; the late Monica Wilson taught me the fundamentals of anthropology and Andrew Spiegel and Robert Thornton struggled to keep me abreast of changes in the discipline; Sue Newton-King and Nigel Penn brought shafts of light from the eighteenthcentury to bear on early industrialism. Charles van Onselen laid a major part of the intellectual foundations on...

...الفصل الأول التعريف بتقنيات التشفير وأمنية المعلومات 1-1:المقدمة ( Introduction ): إن أمنية المعلومات ناتجة من الحاجة إلى تناقل المعلومات الخاصة لكل من العبارات العسكرية والدبلوماسيـة. هذه الحاجة هي قديمة بقدم الحضارة نفسها. الأسبان القدماء مثلا, شفروا عباراتهم العسكرية. أما بالنسبة للصين, فانه يكفي فقط كتابة العبارات بلغتهم المعروفة والتي تعبر لغة خاصة, وذلك لان القليل من الناس يستطيعون قراءة الحروف الصينية. كانت قنوات الاتصال في السابق بسيطة جدا وكانت ترتب بأسلوب يعتمد في تامين السري على استخدام مراسلين موثوقين. تعتمد الأمنية لمثل هذا التنظيم على كل من موضع الثقة للمراسل وقابليته في أن يبقى محتفظا بالمواقف أو المواقع التي فيها يمكن أن تتعرض العبارات للانتهاك. بسبب اكتشاف أنظمة الحاسبات واستخدام شبكات الحاسبة الواسعة بين الدول, فان القرن العشرين قد غير بصورة ملحوظة مدى مفاهيم الحماية. في الحاسبات المبكرة ( الأولى), فان الأمنية الفيزيائية ومعها سياسة الاختيار الملائم للكادر العامل في الحاسبة كان كافيا لتامين الأمنية. لكن هذا أصبح غير كاف وغير مرن بعد اكتشاف أنظمة حاسبات المشاركة الزمنية (Time-Sharing) والتي تتألف من عدة محطات طرفية موزعة في مساحة جغرافية واسعة. من الجدير بالذكر أن امن وسلامة اتصال,ت الالكترونية في بدء ظهورها لم يكن هاما لان معظم المعلومات المخزونة فيها لم تكن ذات حساسية كبيرة, بعكس ماهي عليه اليوم, إذ كلما ازدادت وارتفعت قيمة المعلومات المخزونة في الحاسبات الالكترونية كلما ازدادت الرغبة لدى بعض الأفراد لمحاولة الوصول إليها من اجل التخريب أو من اجل الكسب غير المشروع بواسطة بيعها إلى الجهات الراغبة بذلك, لذا فقد أصبح امن هذه المعلومات على درجة...
