TYPES OF MEMERY

 Although many types of memory in a computer exist, the most basic distinction is between primary memory, often called system memory, and secondary memory, which is more commonly called storage.

The key difference between primary and secondary memory is speed of access.

1. Primary memory includes ROM and RAM, and is located close to the CPU on the computer motherboard, enabling the CPU to read data from primary memory very quickly indeed. It is used to store data that the CPU needs imminently so that it does not have to wait for it to be delivered.

2. Secondary memory by contrast, is usually physically located within a separate storage device, such as a hard disk drive or solid state drive (SSD), which is connected to the computer system either directly or over a network. The cost per gigabyte of secondary memory is much lower, but the read and write speeds are significantly slower.

यद्यपि कंप्यूटर में कई प्रकार की मेमोरी मौजूद होती है, लेकिन प्राथमिक मेमोरी के बीच सबसे बुनियादी अंतर है, जिसे अक्सर सिस्टम मेमोरी और सेकेंडरी मेमोरी कहा जाता है, जिसे आमतौर पर स्टोरेज कहा जाता है।

प्राथमिक और माध्यमिक मेमोरी के बीच महत्वपूर्ण अंतर पहुंच की गति है।

1. प्राथमिक मेमोरी में ROM और RAM शामिल होते हैं, और कंप्यूटर मदरबोर्ड पर CPU के करीब स्थित होता है, जो CPU को प्राथमिक मेमोरी से डेटा को पढ़ने के लिए सक्षम बनाता है। इसका उपयोग उन डेटा को संग्रहीत करने के लिए किया जाता है जो सीपीयू को आसन्न रूप से चाहिए ताकि इसे वितरित होने के लिए इंतजार न करना पड़े।

2. सेकेंडरी मेमोरी, आमतौर पर भौतिक रूप से एक अलग स्टोरेज डिवाइस के भीतर स्थित होती है, जैसे कि हार्ड डिस्क ड्राइव या सॉलिड स्टेट ड्राइव (SSD), जो कंप्यूटर सिस्टम से सीधे या किसी नेटवर्क पर जुड़ी होती है। माध्यमिक मेमोरी की प्रति गीगाबाइट की लागत बहुत कम है, लेकिन पढ़ने और लिखने की गति काफी धीमी 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...
