Understanding computer networks and their conventions can be overpowering, which is why a computer arrange cheat sheet can be useful. This article points to supplying a cheat sheet for computer systems, counting the distinctive sorts of systems, conventions, and innovations utilized. Types of Networks Local Area Network (LAN) A LAN could be an arrangement that interfaces gadgets inside a little geographic zone, like a building or small office. It consists ... Read More

Network Topology Topology defines the interconnection of the components to each other in a network. When a network connection is made between computers with the help of nodes and links then it is defined as network topology. These are broadly classified into a logical and physical topology. Logical topology represents data flow within the network and physical topology represents the connection between computers and one another within the network. In this article, we will discuss the concept of hybrid topology and its advantages and its disadvantages. Hybrid Topology Hybrid topology can be created by combining any two or more different ...

Seeders and leechers are two separate sorts of BitTorrent users. BitTorrent is a peer-to-peer (P2P) file-sharing technology that allows users to download and upload files from and to other users. People who have already downloaded the complete file and are now sharing it with other people are known as "seeds." Leechers are those who are currently downloading the file but haven't finished it yet. Read this article to find out more about Seeds and Leechers and how they are different from each other. What are Seeds? Seeds are users who have already downloaded the complete file and are now sharing ... Read More

RS-232 and RS-485 are two serial communication technologies that are frequently used to transfer data between devices through a serial connection. While both standards are used for serial communication, their properties and applications are quite different. RS-232, commonly known as EIA-232, is a serial communication standard for data transmission between devices. RS-485 is a serial communication standard for data transmission between devices. Read this article to find out more about RS-232 and RS-485 and how they are different from each other. What is RS-232?

PPPoE and PPPoA are two protocols for connecting to the internet through DSL technology. Both protocols allow you to authenticate and connect to your internet service provider (ISP) over a phone line. PPPoE is a protocol that encapsulates PPP frames in Ethernet frames so that they can be carried over Ethernet networks. PPPoA encapsulates PPP frames in ATM cells and allows them to be sent over ATM-based networks. Read this article to find out more about PPPoE and PPPoA and how they are different from each other. What is PPPoE? PPPoE is a protocol that encapsulates PPP frames in Ethernet ... Read More

ITX and ATX are two motherboard form factors used in personal computers. The primary differences between the two are their sizes, compatibility with various components, and number of expansion slots. ITX (or Mini-ITX) is a smaller form factor for motherboards than the standard ATX form factor. ATX (Advanced Technology eXtended) is the standard motherboard form factor and is larger than ITX. Read this article to find out more about ITX and ATX and how they are different from each other. What is ITX? ITX (or Mini-ITX) is a smaller form factor for motherboards than the standard ATX form factor. VIA ... Read More

ADSL (Asymmetric Digital Subscriber Line) and SDSL (Symmetric Digital Subscriber Line) are two digital subscriber line technologies that are used to deliver high-speed Internet access. The main difference between ADSL and SDSL is the way bandwidth is allocated for upstream and downstream data transfers. ADSL is asymmetric, which means that it has different bandwidths for upstream and downstream data transmission. SDSL is an abbreviation for Symmetric Digital Subscriber Line, a form of digital subscriber line technology that is used to deliver high-speed internet access over standard copper telephone lines. Read this article to find out more about ADSL and SDSL ... Read More
