TYPES OF RAM MEMORY

 DRAM: DRAM stands for Dynamic RAM, and it is the most common type of RAM used in computers. The oldest type is known as single data rate (SDR) DRAM, but newer computers use faster dual data rate (DDR) DRAM. DDR comes in several versions including DDR2 , DDR3, and DDR4, which offer better performance and are more energy efficient than DDR. However different versions are incompatible, so it is not possible to mix DDR2 with DDR3 DRAM in a computer system. DRAM consists of a transistor and a capacitor in each cell.

SRAM: SRAM stands for Static RAM, and it is a particular type of RAM which is faster than DRAM, but more expensive and bulker, having six transistors in each cell. For those reasons SRAM is generally only used as a data cache within a CPU itself or as RAM in very high-end server systems. A small SRAM cache of the most imminently-needed data can result in significant speed improvements in a system.

DRAM: DRAM का मतलब है डायनामिक रैम, और यह कंप्यूटर में इस्तेमाल होने वाली सबसे आम रैम है। सबसे पुराने प्रकार को एकल डेटा दर (एसडीआर) DRAM के रूप में जाना जाता है, लेकिन नए कंप्यूटर तेज दोहरी डेटा दर (DDR) DRAM का उपयोग करते हैं। DDR DDR2, DDR3 और DDR4 सहित कई संस्करणों में आता है, जो बेहतर प्रदर्शन प्रदान करते हैं और DDR से अधिक ऊर्जा कुशल होते हैं। हालांकि विभिन्न संस्करण असंगत हैं, इसलिए कंप्यूटर सिस्टम में DDR3 DRAM के साथ DDR2 को मिलाना संभव नहीं है। DRAM में प्रत्येक सेल में एक ट्रांजिस्टर और एक संधारित्र होता है।

SRAM: SRAM स्टैटिक रैम के लिए खड़ा है, और यह एक विशेष प्रकार की रैम है जो DRAM से तेज है, लेकिन अधिक महंगी और भारी है, जिसमें प्रत्येक सेल में छह ट्रांजिस्टर हैं। उन कारणों से SRAM आमतौर पर केवल सीपीयू के भीतर या बहुत उच्च-अंत सर्वर प्रणालियों में रैम के रूप में डेटा कैश के रूप में उपयोग किया जाता है। सबसे आसन्न आवश्यक डेटा का एक छोटा SRAM कैश एक प्रणाली में महत्वपूर्ण गति में सुधार कर सकता है।

ANTIVIRUS

Image
One of the most common reasons for failure or problems in computers is the lack of antivirus software, or expired antivirus software. It is an issue which is often overlooked and has dire consequences for the unfortunate computer owner. Antivirus software is a type of program designed and developed to protect computers from malware like viruses, computer worms, spyware, botnets, rootkits, key loggers and such. Antivirus programs function to scan, detect and remove viruses from your computer. There are many versions and types of anti-virus programs that are on  the market. However, the prime objective of any antivirus program is to protect computers and remove viruses once detected. Most antivirus programs incorporate both automated and manual filtering abilities. The instant scanning option may check files - downloaded from the Internet, discs that are embedded into the PC, and files that are made by software installers. The programmed scanning process may likewise check the entire...

COMPONENTS OF A COMPUTER SYSTEM

Image
 There are several computer systems in the market with a wide variety of makes, models , and peripherals. In general, a computer system comprises following four components: 1. Central Processing Unit (CPU): This unit performs processing of instructions and data inside the computer. 2. Input Unit: This unit accepts instructions and data. 3. Output Unit: This unit communicates the results to the user. 4. Storage Unit: This stores temporary and final results.  1. Central Processing Unit (CPU): Central processing unit is the "administrative" section of the computer system. It interprets, coordinates the operations, and supervises the instructions. CPU works with data in discrete form, that is, either 1 and 0. It counts, lists, compares, and rearranges the binary digits of data in accordance with the detailed program instructions stored within its memory.The CPU itself has three parts: (a). Arithmetic Logic Unit (ALU): This unit performs the arithmetical and logical operations...

COMPUTER ARCHITECTURE

Image
 Computer architecture is a specification detailing how a set of software and hardware technology standards interact to form a computer system or platform. In short, computer architecture refers to how a computer system is designed and what technologies it is compatible with. As with other contexts and meanings of the word architecture, computer architecture is likened to the art of determining the needs of the user/system/technology, and creating a logical design and standards based on those requirements. ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- HINDI TRANSLATE कंप्यूटर आर्किटेक्चर एक विनिर्देश है जो यह बताता है कि सॉफ्टवेयर और हार्डवेयर प्रौद्योगिकी मानकों का एक सेट कंप्यूटर सिस्टम या प्लेटफॉर्म बनाने के लिए कैसे इंटरैक्ट करता है। संक्षेप में, कंप्यूटर आर्किटेक्चर से तात्पर्य है कि कंप्यूटर सिस्टम कैसे डिज़ाइन किया गया है और यह किन तकनीको...
