What is the DHCP Server ? Include installation tutorial

What is DHCP (Dynamic Host Configuration Protocol): DHCP is a network management protocol on Windows servers to automate the process of assigning IP addresses and other network configuration settings to devices on a network. The DHCP server on a Windows server allows clients on the network to automatically obtain an IP address, subnet mask, default gateway, and DNS server information. This helps simplify network administration and eliminates network administrators to manually configure each device on the network. Some of the key roles and functions of DHCP on a Windows server include: IP address management: It automatically assigns IP addresses to…

What is Active Directory? Include Installation tutorial

Network Attached Storage (NAS)

Network Attached Storage (NAS) NAS is a type of data storage that is designed to be accessed and shared over a network. It is a standalone device that can be connected to a network, typically through Ethernet, and provides centralized storage for multiple clients or devices on the same network. NAS devices are often used in homes, small offices, and businesses to store and share files, media, and other data among multiple users or devices. They offer several advantages over other storage solutions, including: Centralized storage: All data can be stored in a specific location, which can be easily accessed and…

Variables in Python

Variables in Programming Language Python The programing languages store data in the form of Variables. Every variable has data type, name, and a value assigned to it. Variables are assigned places in the computer memory to store data in which they can be known or unknown based on the value given to them. Also, they can be used for more than one value. They can tag and store data in memory and we can recall them when we need them. In this section, we want to introduce the most used Variables in Python. In Python, we have four commonly used groups…

Python Standard Library

Python Standard Library With Python Standard Library, we call module code that is ready to use. We cannot use these modules without recall and if we need, we must call them. The Python standard library is very extensive and offers many features. In this library, we see internal modules that are often written in C language. For example, we can access the file input/output system through these modules, without these modules, Python programming will be inaccessible. These modules provide increased programming capabilities. In the installed version of Python in Windows or Mac, usually the entire standard library also install and…
