CISC VS RISC computers (all details)

By
CISC Introduction            The term "CISC" (complex instruction set computer or computing) refers to computers designed with a full set of computer instructions that were intended to provide needed capabilities in the most efficient way. Intel's   Pentium   microprocessors are CISC microprocessors. CISC is a   processor design   where single   instructions   can execute several low-level operations (such as a load from   memory , an arithmetic   operation , and a   memory store ) or are capable of multi-step operations or   addressing modes   within single instructions. The primary goal of CISC architecture is to complete a task in as few lines of assembly as possible. This is achieved by building processor hardware that is capable of understanding & executing a series of operations, this is where our CISC architecture introduced. The CISC approach attempts to minimize the number of instructions per program, sacrificing

DHCP principle , DHCP server and client communication process

By
1. Explain with principle: the DHCP server and client communication process DHCP stands for Dynamic Host Configuration Protocol. It handles the automatic assignment of IP addresses and other configuration settings for devices on your network. DHCP automates Network and Sharing Center in your control panel. This is especially good for people who have laptops, aren't hooked up to the Internet all the time and often move from place to place with their portable devices. They can simply get a new IP address as needed without having to do it manually. DHCP is designed to make the assignment of IP addresses and other network configuration information faster and easier. DHCP is a protocol that uses Level 4 on the OSI model. It communicates using User Datagram Protocol (UDP) datagrams through UDP Port 68. DHCP works with most current and past Windows clients, and also Linux, Macintosh, and many network-capable printers. DHCP is desi

Recommendation System literature review | Building a recommendation system

By
People have always relied on the recommendations from their peers or the advice of experts to support their decision making. Amazon.com has been using collaborative filtering for a decade to recommend products to their customers, and Netflix valued improvements to the recommender technology underlying their movie rental service at $1M via the widely published Netflix Prize [6]. Research on recommender algorithms garnered significant attention in 2006 when Netflix launched the Netflix Prize to improve the state of movie recommendation. The objective of this competition was to build a recommender algorithm that could beat their internal CineMatch algorithm in offline tests by 10%. It sparked a flurry of activity, both in academia and amongst hobbyists. The $1 M prize demonstrates the value that vendors place on accurate recommendations [8]. Recommender Systems provide the users with the suggestions of information that may be useful to the users to make their decisions on various sit

Windows 10 Preview Build 14257 for PC Available for insiders

By
If you are using Windows 10 Insider Preview (previously known as Technical Preview) in your computer, here is a good news for you.
Microsoft has released a new update Build 14257 of Windows 10 to public which comes with many bug fixes and improvements. This is the 5th Insider Preview build of Windows 10 released after the November Update build 10586 (Threshold 2). This new build also comes via new "RS1" (RedStone1) development branch.
This build doesn't contain big noticeable changes or exclusive features. It is basically focused on bug fixes and general improvements.
WHAT'S FIXED:
  • The issue of periodic app crashes or other memory related app errors due to a memory management change has been resolved. If you were having issues launching the Git client for Windows, you should now be able to launch it in this build.
  • The Connect button now shows up again in Action Center.
  • F12 Developer Tools will now load correctly in Microsoft Edge web browser.
  • [Fixed] Suggested apps were being shown on the Start menu even though "Occasionally show suggestions in Start" option was disabled under Settings -> Personalization -> Start page.
  • [Fixed] If you try to change the Lock screen picture with "Get fun facts, tips, tricks and more on your lock screen" option enabled, it will revert back to the default.
  • [Fixed] The positions of desktop icons get jumbled up after switching DPI settings from 100% to 150% or 175%.
  • [Fixed] Pasting files into a new .zip file (compressed folder) in File Explorer by either right-clicking or Ctrl+V hotkey would not work. You should be able to paste tiles into new .zip files just fine now.
KNOWN ISSUES:
  • You might see a WSClient.dll error dialog after logging in. Microsoft is working on a fix for this but as a workaround, you can run following command in Command Prompt as Administrator:schtasks /delete /TN "\Microsoft\Windows\WS\WSRefreshBannedAppsListTask" /F
  • If you choose "Reset This PC" from Settings -> Update & Security -> Recovery page, your PC will be in an unusable state. There is no workaround if your PC gets into this state and you will need to reinstall Windows. This issue will be fixed in the next build. You can still rollback to the previous build if for some reason this build doesn't work out for you. This bug also existed in previous build 14251 so avoid resetting your PC on these builds.
  • The front-facing camera is unusable on PCs with Intel RealSense resulting in being unable to use Windows Hello or any other apps that utilize the front-facing camera.
  • After logging in to your PC, you may hit a UI issue in which Airplane Mode will incorrectly show as ON even though your PC's Wi-Fi is powered on. This is due to a timing issue between how the UI communicates and waits for the underlying platform to respond. The UI for Airplane Mode essentially does not wait long enough for the device's physical radios to power on before reporting the current state. You can toggle the Airplane Mode on and off to get Airplane Mode back to showing the correct state.
HOW TO INSTALL:
The new build is available for download via Windows Update, so it'll be automatically downloaded and installed in all computers running Windows 10 Insider Preview soon.
If you want to manually download and install the new build ASAP, you can do this using following simple steps:
1. Open Settings app from Start Menu.
2. Click on Update and security icon.
3. Once you open Windows Update section, it'll automatically start checking for new builds. Otherwise you can click on "Check for updates" button.
4. Click on "Download now" button to start downloading the new update build of Windows 10.
After downloading the build, your computer will automatically restart to install the new update.
The download size will be around 2 or 3 GB depending upon the computer architecture (32-bit or 64-bit) and system language.
