Client-server Model

What is Client-server Model?

It is a distributed application structure that partitions tasks or workloads between the providers of a resource or service called servers, and service requesters called clients. The connection is established through a local network or over the internet. Therefore in a client-server architecture, when the client requests a service or resources to the servers through the internet, the servers accept the client's request and delivers the resources or services to the client. For example, the Servers include web servers, database servers, chat servers, email servers, and file servers and the clients include email software, web browser, files, and chat application. The client devices are such as laptops, desktop computers, tablets, and smartphones.

Virtual Private Network (VPN)

What is Virtual Private Network (VPN)? A virtual private network (VPN) is a secure connection between two private networks over a public network (in other words, over the Internet). All the data that flows over the VPN is encrypted. So anyone who steals packets from the VPN will find them unintelligible; only the parties on either end of the VPN are able to decrypt the packets. VPN connections are often called tunnels. Because they provide an isolated pathway from one point to another through the Internet. The only way to gain meaningful access to a VPN tunnel is at either end. Example for VPN Connections VPNs are used for There are two common uses for VPNs: To provide remote workers with secure access to your company network: To do that, you set up a VPN on the router, and then provide your remote workers with the credentials necessary to access the VPN. The remote workers can run a software VPN client on their home computers or laptops to connect to

Motherboard

What is Motherboard? Motherboard If the processor is the brain of the computer, the motherboard is the heart of the computer. The motherboard is the main circuit board inside the computer and however, all the components and peripherals are attached to it. Therefore the most of the compute features like scalability and upgradeability depend on the motherboard. Computer Motherboard Components Components of Motherboard Key Assessable Parameters of Motherboard Form factor Chipset CPU Memory Audio Ports and Slots Headers and Connectors BIOS Form factor The root mean square value ratio to the average value ratio of the alternating current is called Form Factor and it is the ratio of the root mean square value to the average value is also known as the absolute value of the waveform. Measurements of Form Factor, Form Factor Formula Where RMS is Root Mean Square Value, AV is Average Value Ir.m.s is the root main square value of current, therefore Iav are
