BASIC MEMORY ARCHITECTURE INTRODUCTION

BASIC MEMORY ARCHITECTURE

INTRODUCTION 
        Computer data storage, often called storage or memory, refers to computer components, devices, and recording media that retain digital data used for computing after some interval of time. Computer data storage provides one of the core functions of the modern computer, that of information retention. It is one of the fundamental components of all modern computers, and coupled with a central processing unit (CPU, a processor), implements the basic computer model used since 1940s. 

    People often confuse the terms memory and storage, when describing. The term memory refers 
to the amount of RAM installed in the computer, whereas the term storage refers to the capacity of the
computer’s hard disk so we can define memory as the place where computer holds programs and data 
that are in use. Although memory is technically any form of electronic storage, it is used most often to 
identify fast, temporary forms of storage. If computer’s CPU had to constantly access the hard drive to 
retrieve every piece of data it needs, it would operate very slowly. When the information is kept in 
memory, the CPU can access it much more quickly. Most forms of memory are intended to store data 
temporarily. Historically, memory and storage were respectively called primary storage and secondary 
storage.

BIOS

BIOS       BIOS is a software which resides in a small flash EEPROM memory on the motherboard. It is a  form of read only memory (ROM), but may be rewritten or programmed when the right tools and  techniques are applied. It works as an interface between the computer hardware and operating system  and communicates between computer and devices.       The BIOS is very important part of your computer that makes its home on the motherboard. The BIOS provides an interface between the raw PC hardware and the standard operating system, it is usually stored in ROM. As you can see, BIOS is important; every computer needs it. And like CPU's, it comes in different versions. BIOS versions are based on years. These chips are typically the biggest chips on your motherboard other than the CPU and math-coprocessor. There is usually a big sticker on it that says BIOS. The sticker also says what kind of BIOS it is and what year the BIOS were published...

What is Software ?

What is Software ?   What is Software ?   The programs that tell the hardware what tasks are to be done and how. it is the general terem which describes all forms of programs associated with the computer. software is the set of programs that is  essential  to perform any task on the computer. Type of Software Operating System      The program that communicates between all components of a computer is known as operating system computer must have an operating system to run other programs. Operating systems perform basic tasks, such as recognizing input from the keyboard, sending to the display screen, keeping track of directories on the disk, and controlling devices such as disk drives and printers Operating systems can be classified as follows:  Multi-user : Allows two or more users to run programs at the same time. Some operating systems  permit hundreds or even thousands of concurrent users. Windows server 2003, Unix etc are the example ...

What is Computer ? कम्प्यूटर क्या है?

WHAT IS A COMPUTER?       Computer is a device which accepts input, processes it, stores the data, if required and gives desired output as per user requirement. The term computer is used to describe a device made up of a  combination of electronic and electromechanical (part electronic and part mechanical) components. By itself, a computer has no intelligence and is referred to as hardware. In general the computer does the  following.  1. Accept user supplied data and instructions.  2. Stores large volume of information given at high speed as per the instruction given.  3. Process the information given at a high speed as per the instruction given.  4. Output the results according to user specifications 5. Transfers Data, Images, Sound and Graphics through cables at a very fast rate       In other words, we supply to the computer; the data to be processed and the instructions to  process the data with. The compute...

Computer Generation/कंप्यूटर निर्माण की पीढियां

 पहली पीढ़ी कंप्यूटर (1946-1954)     इलेक्ट्रॉनिक वाल्व (वैक्यूम ट्यूब) का उपयोग करने वाले डिजिटल कंप्यूटर को पहली पीढ़ी के रूप में जाना जाता है। पहली पीढ़ी के कंप्यूटरों के कुछ उदाहरण हैं इंटरनेशनल बिजनेस मशीन की IBM-700 श्रृंखला IBM-701, IMB-709, EDVAC (इलेक्ट्रॉनिक डिस्क्रीट वेरिएबल ऑटोमैटिक कंप्यूटर), और UNIVAC (यूनिवर्सल ऑटोमैटिक कंप्यूटर)। पहली पीढ़ी के कंप्यूटर आमतौर पर सीपीयू घटकों के रूप में वैक्यूम ट्यूबों का उपयोग करते थे। वैक्यूम ट्यूबों की उच्च लागत ने मुख्य मेमोरी के लिए उनके उपयोग को रोक दिया। MIT में निर्मित बवंडर I, फेराइट कोर मेमोरी का उपयोग करने वाला पहला कंप्यूटर था। पहली पीढ़ी के कंप्यूटर प्रोग्रामिंग के लिए विधानसभा भाषा का इस्तेमाल किया। वे निश्चित-बिंदु अंकगणित का उपयोग करते थे। दूसरी पीढ़ी  कंप्यूटर (1955-1964)     दूसरी पीढ़ी के कंप्यूटरों में सीपीयू घटकों के लिए उपयोग किए जाने वाले ट्रांजिस्टर, मुख्य मेमोरी के लिए फेराइट कोर और द्वितीयक मेमोरी के लिए चुंबकीय डिस्क, ड्रम और टेप होते थे। उन्होंने प्रोग्रामिंग के लिए उच्च स्तरीय भाषा...

ईथरनेट शब्दावली /Ethernet Terminology

           ईथरनेट   शब्दावली   ईथरनेट नियमों के एक सरल सेट का अनुसरण करता है जो इसके मूल संचालन को नियंत्रित करता है। इन नियमों को बेहतर ढंग से समझने के लिए, ईथरनेट शब्दावली की मूल बातें समझना महत्वपूर्ण है।  मध्यम   (Medium) ईथरनेट डिवाइस एक सामान्य माध्यम से जुड़ते हैं जो एक रास्ता प्रदान करता है जिसके साथ इलेक्ट्रॉनिक सिग्नल यात्रा करेंगे। ऐतिहासिक रूप से, यह माध्यम समाक्षीय तांबा केबल रहा है, लेकिन आज यह अधिक सामान्यतः एक मुड़ जोड़ी या फाइबर ऑप्टिक केबलिंग है।   खंड ( Segment ) हम ईथरनेट खंड के रूप में एकल साझा माध्यम का उल्लेख करते हैं। नोड डिवाइस जो उस सेगमेंट से जुड़ते हैं वे स्टेशन या नोड होते हैं। ढांचा नोड्स छोटे संदेशों में कहे जाते हैं, जिन्हें फ्रेम कहा जाता है, जो सूचनाओं के भिन्न आकार होते हैं।  फ़्रेम ( Frame )  मानव भाषा में वाक्यों के अनुरूप हैं। अंग्रेजी में, हमारे वाक्य बनाने के नियम हैं: हम जानते हैं कि प्रत्येक वाक्य में एक विषय और एक विधेय होना चाहिए। ईथरनेट प्रोटोकॉल फ्रेम के निर्माण के लिए नियमों क...

Ethernet/ईथरनेट

         ईथरनेट (Ethernet)  ईथरनेट एक ऐसा प्रोटोकॉल है जो सभी डिवाइसों को सभी साझा किए गए एकल केबल की मदद से नेटवर्क पर अन्य सभी उपकरणों के साथ संचार करने में सक्षम बनाता है। यह मूल रूप से दो सरल पर काम करता है प्रधान अध्यापक:- 1. एक निश्चित समय पर केवल एक उपकरण संचारित होगा और बाकी सभी वाहक के सुनने में होंगे। पैकेट सभी को भेजा जाएगा लेकिन केवल सही नोड द्वारा प्राप्त किया जाएगा। बाकी सभी नोड इस पैकेट को अस्वीकार कर देंगे। एक बार पैकेट को अग्रेषित करने के बाद अगला उपकरण समाप्त हो जाएगा और अन्य सभी सुनने में होंगे। 2. यदि दो डिवाइस एक ही समय में अग्रेषित करना शुरू करते हैं तो पैकेट की टक्कर होगी और संवेदन के बाद दोनों उपकरण प्रसारण बंद कर देंगे और फिर से एक-एक करके प्रसारण शुरू कर देंगे।   1973 में, ज़ेरॉक्स कॉरपोरेशन के पालो ऑल्टो रिसर्च सेंटर (जिसे आमतौर पर PARC के रूप में जाना जाता है) में, शोधकर्ता बॉब मेटकाफ ने पहले ईथरनेट नेटवर्क का डिजाइन और परीक्षण किया। ज़ेरॉक्स के "ऑल्टो" कंप्यूटर को प्रिंटर से लिंक करने के तरीके पर काम करते समय, मेटकाफ ने केब...

TYPES OF RAM AND ROM

TYPES OF RAM AND ROM  Common RAM Types  • SRAM       Static random access memory uses multiple transistors, typically four to six, for each memory cell  but doesn't have a capacitor in each cell. It is used primarily for cache. These types of memory are physically bulky and somewhat limited to its capacity.       In Static RAM, a form of flip-flop holds each bit of memory. A flip-flop for a memory cell takes four or six transistors along with some wiring, but never has to be refreshed. This makes static RAM significantly faster than dynamic RAM. However, because it has more parts, a static memory cell takes up a lot more space on a chip than a dynamic memory cell. Therefore, you get less memory per chip, and that makes static RAM a lot more expensive      Static RAM is fast and expensive, and dynamic RAM is less expensive and slower. Static RAM is  used to create the CPU's speed-sensitive cache, while dynamic RAM...
