In this article, I have tried to collect UART Interview questions that can be asked by your Interviewer. A UART is a chip for asynchronous serial communication. It takes bytes of data and transmits the individual bits in a sequential fashion with the help of a shift register. The shift…
Before understanding the framing in data link layer we need to understand some common terminology. Datagram: The unit of transmission in the network layer (such as IP). A datagram may be encapsulated in one or more packets passed to the data link layer. Frame: The unit of transmission at the…
In this blog post, we will see the difference between SSL and TLS (SSL vs TLS). SSL stands for Secure Socket Layer and TLS stands for Transport Layer Security. Both SSL and TLS are protocols that help you securely authenticate and transport data on the Internet. Because TLS is an…
The basic difference between Http and https is that https is more secured then Http. Before comparing the Http and Https we want to give some introduction of HTTP and HTTPS. What is HTTP? HTTP stands for “HYPERTEXT TRANSFER PROTOCOL” and use to view the web page. When you enter…
Transport Layer Security (TLS) is an upgraded version of the Secure Sockets Layer (SSL). TLS is an encryption protocol intended to keep data secure when being transferred over a network. Client-server applications use the TLS protocol to communicate across a network in a way designed to prevent eavesdropping and tampering….
The major difference between High-level Data Link Control (HDLC) and Point-to-Point Protocol (PPP) is that High-level Data Link Control is the bit-oriented protocol, while the Point-to-Point Protocol is the byte-oriented protocol. HDLC protocol supports half-duplex full-duplex transmission, point-to-point, and multi-point configuration and switched or non-switched channels. While PPP is implemented…
This article is mainly focused on the most repeatedly asked embedded system interview questions. If you are looking for “embedded system interview questions” or “simple questions on embedded systems”, then you at the right place. Here I have tried to create some collection of “embedded system interview questions with answers”…
If you are looking for “SPI interview questions” or “SPI protocol basics, then you at the right place. Previously I have created a list of “embedded c interview questions” that is liked by many people. I have got the response to create a list of interview questions on the “SPI…
Nowadays there are a lot of devices that use the serial interface for data transmission. When I am talking about the serial interface then there are a lot of serial interfaces are available like I2C, SPI, USB and many more. But the two oldest serial interfaces RS232 and Rs475 are…
In this blog post, you will know the difference between UART and USART (UART vs USART). Both UART and USART chips are made by manufacturers to convert incoming and outgoing bytes of data into a serial bitstream. As an embedded engineer it is good to know the actual differences…
