Random Access Memory (RAM)

What is Random Access Memory (RAM)?

The Random Access Memory is a volatile memory or temporary storage device and its use to store working data and machine code and Random Access Memory allows data to read or write in the physical location of data in contact with direct access to storage media such as DVD read/write, CD read/write, and hard disk. Therefore it is a part of the computer’s main memory, which is directly accessible by CPU and it is volatile in nature, it means if the power goes off, the stored information is lost and it is used to store the data that is currently processed by the CPU and most of the programs and data that are modifiable are stores in RAM.

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 connec...

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 ...
