A search engine is a software program or script available through the internet that searches documents and files for keywords and returns the results of any files containing those keywords.Today,There are thousand of different search engines available on the internet, each with their own abilities and features. The first search engine ever developed is considered.Archieve , which was used to search for FTP files and the first text -based search engine considered veronica. today,The must popular and well known search engine is Google. Type of search engine: Google All the web  Teoma Inktami Yahoo Uses of search engine: Results are the hyperlinks to websites that show up in the search engine page when a certain keyword or phrase is queried. When you type in a search term, the crawler runs through the index and matches what you typed with other keywords. Algorithms created by the search engine designers are used to provide the most relevant data first. Each searc...

Welcomec to techusers. Nearly every computer and related device needs RAM. Let's Take a look at your favourite device (e.g. smart phones, tablets, desktops, laptops, graphing calculators, HDTV, handheld gaming systems, etc.), and you should find some information about the RAM. Although all RAM basically serves the same purpose, there are a few different types commonly in use today: Static RAM (SRAM) Dynamic RAM (DRAM) Synchronous Dynamic RAM (SDRAM) Single Data Rate Synchronous Dynamic RAM (SDR SDRAM) Double Data Rate Synchronous Dynamic RAM (DDR SDRAM, DDR2, DDR3, DDR4) Graphics Double Data Rate Synchronous Dynamic RAM (GDDR SDRAM, GDDR2, GDDR3, GDDR4, GDDR5) Flash Memory What Is RAM? RAM stands for Random Access Memory, and it gives computers the virtual space needed to manage information and solve problems at the moment. You can think of it like reusable scratch paper that you would write notes, numbers, or drawings on with a pencil. If you run out of room on the paper, you...

All of us hear these terms on daily basis. We had GPRS earlier. Then came 3g, then 4g and now people are talking about 5g. What exactly these are & what do they specify. Let us see. The ‘G’ here,  refers to the " generation " of wireless network technology. 1G networks  (NMT, C-Nets, AMPS, TACS) are considered to be the first analog cellular systems, which started early 1980s. There were radio telephone systems. 1G networks were conceived and designed purely for voice calls with almost no consideration of data services. 2G networks  (GSM, CDMAOne, D-AMPS) are the first digital cellular systems launched early 1990s, offering improved sound quality, better security and higher total capacity. GSM supports circuit-switched data (CSD), allowing users to place dial-up data calls digitally, so that the network's switching station receives actual ones and zeroes rather than the screech of an analog modem. 2.5G n...
