Introduction What is the purpose of using a computer? If we ask this simple question, we will realize that we use it to do tasks. But those tasks are done using computers because of their ease of use. For example, we do our assignments or document our work using various programs like Microsoft Office, OnlyOffice, LibreOffice, Google Docs, etc. Well, those are programs or applications we use. Those programs or applications are made using programming languages. As humans, we speak different languages. Similarly, there are different programming languages. But why are there so many different languages? Won’t it be easy if there is only one programming language? Well, it surely would be. But different languages have different strengths and weaknesses. Some languages are better suited for front-end development, others for back-end development, still others for application development, and so on. ...

Powershell What exactly is PowerShell? Powershell is a task automation solution as well as a command line shell. Similar programs include bash, zsh, and others. PowerShell, on the other hand, is now cross-platform. It is now available for download on Windows, Mac, and Linux. This increases its versatility. But one thing people are afraid of is the command line. Powershell can only be run from the command line. So why not make it more appealing to use? We are drawn to beautiful things as humans. Furthermore, rather than using a graphical user interface, powershell allows you to perform many tasks quickly. So, if we make the terminal more appealing, we will be able to encourage more people to use it. We can now start thinking about how to improve it. ...

Introduction Latches and flip-flops play important roles in the building of digital CMOS circuits. Timing elements such as flip-flops and latches in addition to the building blocks of any clocking system, form the most important components in synchronous VLSI system. Moreover, the key signal in all synchronous systems is the apparent clock and clock signal is normally heavily loaded by all the latches and flip-flops in the chip, and by the clock distribution network that covers the whole chip. Lastly, although the activity ratio of the clock signal is unity, the interconnection length of the clock trees has been increasing radically. The design trend is thus to increase the pipeline stages for high throughput, and this has prompted the increased in the number of latches and flip-flops in a chip. ...

Introduction Nowadays, the use of private vehicles is very common, so the number of vehicles on the road is increasing exponentially. Roads without supervision or guidance can lead to traffic jams and accidents. Traffic lights are signaling devices used to control the flow of traffic. The traffic lights will provide directions to users (drivers and pedestrians) through lights displaying standard colors. The three colors used for traffic lights are (red, yellow and green). This system should be used to control traffic lights to ensure smooth and safe traffic. ...

Introduction The Water Level Indicator employs a simple mechanism to detect and indicate the water level in an overhead tank or any other water container. The sensing is done by using water sensor . There are a lot of water sensor models available in the market like water sensor(china) model SEN-00235, Grove- water sensor model SEN-00042, water flow sensor model SEN-00043 etc. For this project we’ll use the water sensor (china) model SEN-00235 because it’s cheap & economical. The arduino uno is used for the project to run through coding. Water level indicator will inform the user about different level of water that a container is containing i.e, high/ average/ low . there is also a buzzer system attached to the circuit to let an user know when the container is full. ...
