LOGO Drawing Programming Language

LOGO Drawing Programming Language

LOGO Drawing Programming LanguageLOGO Drawing Programming Language - LOGO Language was designed in 1967 by Wally Feurzeig, Seymour Papart and Cynthia Solomon at Bolt, Beranek and Newman (BBN), a Cambridge, Massachusetts research firm. Logo is popularly known for its use of turtle graphics, in which commands for movement and sketching produces line graphics on screen or with a small robot called turtle. Logo programming language is so designed that it help kids to learn programming easily. Instead of learning theory or going through complicated programming structures, users can learn programming basics with simple words and directions. The logo Programming Language is also called as a dialect of Lisp, was designed as a tool for learning.

What are features of LOGO Programming language?

  1. Most known features is the turtle, as an on screen 'cursor' that showed output from commands for movement and small pen together developing line graphics.

  2. Interactivity – It helps out the programmer at the time of debugging and learning process by prompting Error message in descriptive form. It also provide immediate feedback to user during processing.

  3. Flexibility – It is flexible in terms of words and lists following strict rules regarding integrity of data.

  4. Enhancements – it contains enhance features while working for different works. These are Object oriented Concepts, Multi-tasking, language features etc.

  5. Modularity and Extensibility – It usually contains a number of small procedures which are used with the special word 'TO' followed by the name of procedure.

  6. A Turtle robot, which is controlled by users workstation that is designed to carry out drawing functions allocating to it using a small retractable pen which are set into or attached to the robots body.

The language is modular, extensible, interactive, and flexible. The experienced programmers can perform complex tasks and build sophisticated projects by using features of LOGO Programming Language. It provides the student with a rich set of numerical and symbolic proto types as an element for complex program structures. The creation of these structures is greatly influenced by a procedure-oriented programming heuristic and by recursive programming.

One of the two major properties which were designed into Logo is turtle graphics. A turtle composed of a triangle or symbol which are controlled by commands from the keyboard or from within a Logo program. For example, the command FORWARD 60 RIGHT 80 will tell the turtle to move forward 60 units and turn right 80 degrees. The advantages of using turtle graphics are obvious to anyone to use logo. Logo language is procedural language.

When Task Scheduler gets Infected by Malware

When Task Scheduler gets Infected by Malware

When Task Scheduler gets Infected by Malware - We are familiar with malware attacks on Computer. The hackers infect one or more files and thereby attaining full control on the System. There are millions of victims who had loosen either data or dollars in this respect. In this article we see a System file which is infected by these hackers at first stage. The System file infected by malware at first stage is Task Scheduler Engine (Taskeng.exe). The Task Scheduler Engine is a system file located in C:\Windows\System32 folder. This location is the default location for Taskeng.exe.

The Task Scheduler Engine is responsible for keeping track of tasks set to run at a time predefined by the user of the PC. As said earlier, the original location of this scheduler is C:\Windows\System32 folder. But it is suspicious if the location of scheduler gets change. If it is found in some other folder then it must be infectious. As a result, you constantly get a…

How to Project Android Phone Screen on Windows PC

Project Android Phone Screen on Windows PC - Four out of Five of us have Smartphones in our Pocket. We spend lots of time on Smartphone utilities like Facebook, Twitter, WhatsApp, YouTube and other interesting Apps. These Smartphones are tremendously used due to Android Operating System installed in it. Android OS is one the successful mobile based OS running in the market.

On the Other side, Microsoft is emphasizing on features to ease Android user's connectivity with it. Microsoft has done lots of improvement for mobile utilities to the Windows 10 version 1809. With this upgradation, we can easily project Android phone screen on Windows PC. The extensive use of such features is seen on Digital Smart TVs Today. The introduction of Wi-Fi feature makes more reliable and user friendly.

So, if you are boredom with 5-6-inch Android Screen and want to mirror it on Computer screen, then read the full article to know the process, how to proj…

Fix Windows could not find a driver for your network adapter error

Fix Windows could not find a driver for your network adapter error

A Computer run smoothly with the coordination of Software & Hardware. In the absence of any one it will not run at all. Software being the Master utilizes each hardware attached to the System. And each hardware is operated with the help of Device Drivers installed in it. Operating System (OS) uses these device drivers to control & utilize each hardware when needed. Each hardware connected to the system must have their own Device Driver installed. A device driver is a program to initiate a hardware when required by Operating System.

Suppose, you want your PC to connect to the Network, it can only be possible when your PC has network related Device Driver. These Device Drivers are easily downloaded from Manufacturer Websites. In this article we focus on Network related problem. Suppose, your PC not obtaining Network connectivity. And each time you are getting an error message saying "Windows could not find a d…
