What is AUTOSAR? AUTOSAR (AUTomotive Open System ARchitecture) is a worldwide development partnership of automotive manufacturers, suppliers, and other companies in the electronics, semiconductor, and software industries. AUTOSAR standards are designed for software standardization, reuse, and interoperability. AUTOSAR has implemented a layered architecture similar to OSI model. It has different layers to handle and abstract different operations ofContinue reading “AUTOSAR”

What Is a Software-Defined Vehicle? A Software-Defined Vehicle is any vehicle that manages its operations, adds functionality, and enables new features primarily or entirely through software. it reflects the gradual transformation of automobiles from highly electromechanical terminals to intelligent, expandable mobile electronic terminals that can be continuously upgraded. To become such intelligent terminals, vehicles areContinue reading “Software-Defined Vehicles – A Forthcoming Industrial Evolution”

Software testing plays a vital role in ensuring the quality, reliability, and performance of software applications. It covers a diverse range of testing types, each designed to address specific aspects of a software system. Based on actions: a. Manual Testing: Manual testing is the process of executing test cases and scenarios without the assistance ofContinue reading “Software Testing Types”

What is Unified Diagnostic Service (UDS) Protocol? With rapid implementation of electronic embedded systems in vehicles, the need to track and control the vehicle’s different parameters was imperative. Thus, diagnostic systems were developed so that the clients (designers, testers, and mechanics) could detect the faults in the vehicle by connecting their diagnostic tester tool toContinue reading “Unified Diagnostic Services (UDS)”

Protocols and Standards A network is basically all of the components (hardware and software) involved in connecting computers and applications across small and large distances. When designing and maintaining a network, remember these factors: cost, security, speed, topology, scalability, reliability, and availability  some of the more common networking applications include e-mail applications for sending mail electronically, FileContinue reading “OSI Model”

ENCAPSULATION AND DE-ENCAPSULATION As this information is passed from higher to lower layers, each layer adds information to the original data—typically a header and possibly a trailer. This process is called encapsulation Generically speaking, the term protocol data unit (PDU) is used to describe data and its overhead. Going Down the Protocol Stack The first thing that occursContinue reading “Encapsulation-Decapsulation & Different Standard Ethernet Frame Formats”

Introduction Internet addresses allow any machine on the network to communicate with any other machine on the network. TCP/IP provides facilities that make the computer system an Internet host, which can attach to a network and communicate with other Internet hosts The TCP/IP protocol stack actually doesn’t define the components of the network access layerContinue reading “TCP/IP Protocol & Frame Structure of IP”

Transmission Control Protocol TCP uses a reliable delivery system to deliver layer 4 segments to the destination. This would be analogous to using a certified, priority, or next-day service with the US Postal Service. For example, with a certified letter, the receiver must sign for it, indicating the destination actually received the letter: Proof ofContinue reading “Transport Layer Protocols TCP-UDP”

ARP (Address Resolution Protocol) is a network protocol used to find out the hardware (MAC) address of a device from an IP address. It is used when a device wants to communicate with some other device on a local network (for example on an Ethernet network that requires physical addresses to be known before sendingContinue reading “ARP (Address Resolution Protocol)”

An IP address is an address used in order to uniquely identify a device on an IP network. The address is made up of 32 binary bits, which can be divisible into a network portion and host portion with the help of a subnet mask The 32 binary bits are broken into four octets (1Continue reading “IPv4 – Addressing”
