TYPES OF ROM MEMORY

 PROM : PROM stands for Programmable Read-Only Memory, and it is different from true ROM in that while a ROM is programmed (i.e. has data written to it) during the manufacturing process, a PROM is manufactured in an empty state and then programmed later using a PROM programmer or burner.

EPROM : EPROM stands for Erasable Programmable Read-Only Memory, and as the name suggests, data stored in an EPROM can be erased and the EPROM reprogrammed. Erasing an EPROM involves removing it from the computer and exposing it to ultraviolet light before re-burning it.

EEPROM : EEPROM stands for Electrically Erasable Programmable Read-Only Memory, and the distinction between EPROM and EEPROM is that the latter can be erased and written to by the computer system it is installed in. In that sense EEPROM is not strictly read-only. However in many cases the write process is slow, so it is normally only done to update program code such as firmware or BIOS code on an occasional basis.

HINDI TRANSLATE

PROM: PROM का मतलब प्रोग्रामेबल रीड-ओनली मेमोरी होता है, और यह सत्य ROM से अलग होता है जबकि विनिर्माण प्रक्रिया के दौरान एक ROM प्रोग्राम किया जाता है (यानी इसमें डेटा लिखा होता है), एक PROM एक खाली अवस्था में निर्मित होता है और फिर बाद में प्रोग्राम किया जाता है। PROM प्रोग्रामर या बर्नर का उपयोग करना।

EPROM: EPROM का मतलब है इरेज़ेबल प्रोग्रामेबल रीड-ओनली मेमोरी, और जैसा कि नाम से पता चलता है, EPROM में स्टोर किया गया डेटा मिटाया जा सकता है और EPROM को फिर से शुरू किया जा सकता है। EPROM को मिटाने में इसे कंप्यूटर से निकालना और इसे फिर से जलाने से पहले पराबैंगनी प्रकाश में उजागर करना शामिल है।

EEPROM: EEPROM का अर्थ है इरेक्टेबल इरेज़ेबल प्रोग्रामेबल रीड-ओनली मेमोरी, और EPROM और EEPROM के बीच का अंतर यह है कि उत्तरार्द्ध को मिटाया जा सकता है और इसे उस कंप्यूटर सिस्टम द्वारा लिखा जा सकता है जिसे यह स्थापित किया गया है। इस अर्थ में EEPROM सख्ती से केवल पढ़ने योग्य नहीं है। हालाँकि कई मामलों में लिखने की प्रक्रिया धीमी होती है, इसलिए यह आमतौर पर प्रोग्राम कोड जैसे फर्मवेयर या BIOS कोड को कभी-कभार अपडेट करने के लिए किया जाता 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...
