We shall study the common bus system of a very basic computer in this article. A basic computer has 8 registers, memory unit and a control unit. The diagram of the common bus system is as shown below.
The input unit provides data to the computer system from the outside. So, basically it links the external environment with the computer. It takes data from the input devices, converts it into machine language and then loads it into the computer system. Keyboard, mouse etc. are the most commonly used input devices.

Generally, computers use many registers for different purposes. We need to transfer the data and instruction between these registers. So, To transfers the data between the registers, the common bus system is used . For this, we connect all registers with a common BUS through Multiplexer.
In this article, we will learn about 4-bit and 8-bit registers architecture but mostly registers are 16-bit in computer architecture. The concept of working of common bus system in 4-bits, 8bits or 16 bits is almost same.
Tmax XT with Ekip Com offers the possibility to choose between more than ten communication protocols. Dedicated Com modules can be snapped directly onto the switch, for example for Modbus RTU, Profibus DP and Devicenet, enabling communication via the most common fieldbuses. The Modbus module ensures fast integration of new products into existing systems. Up to 246 devices can be connected to one line of a master/slave architecture at a communication speed of up to 38,400 kilobits per second. Profibus DP is the perfect choice for automation switchgear where fast data exchange is required. The maximum transfer rate is 12 megabits per second in a master/slave or multimaster architecture that connects up to 125 devices.
SOA, or service-oriented architecture, defines a way to make software components reusable and interoperable via service interfaces. Services use common interface standards and an architectural pattern so they can be rapidly incorporated into new applications. This removes tasks from the application developer who previously redeveloped or duplicated existing functionality or had to know how to connect or provide interoperability with existing functions.
Note that although SOA, and the more recent microservices architecture, share many words in common(i.e. "service" and "architecture"), they are only loosely related and, in fact, operate at different scopes, as discussed later in this article.
The concept of the enterprise service bus is analogous to the bus concept found in computer hardware architecture combined with the modular and concurrent design of high-performance computer operating systems. The motivation for the development of the architecture was to find a standard, structured, and general purpose concept for describing implementation of loosely coupled software components (called services) that are expected to be independently deployed, running, heterogeneous, and disparate within a network. ESB is also a common implementation pattern for service-oriented architecture, including the intrinsically adopted network design of the World Wide Web.

This course covers both, the lecture DM544 and DM548. The first part of the course, the computer architecture part, is common to both courses. The 5 ECTS DM544 course ends around mid-term and will be completed with an oral exam. In this time the course introduces the student to the architecture of general purpose computers, from the logic level over the microprogramming level to the conventional ISA level; also major components in the storage hierarchy, bus architectures and the organization of pipelined CPU's are presented. 2ff7e9595c
