Posted on 29 December 2020 by admin. Using a Cross-Functional flowchart is a clear way of showing each team member’s responsibilities and how processes get shared or transferred between different teams and departments. Taking data and instructions from a user, processing the data as per instructions, and displaying or storing the processed data, are the four major functions of a computer. June 21, 2017 in Computer Fundamental, Notes. 1 . Flowcharts Diagram Of Computer System Unit. CPU is the brain of computer system. Computer Architecture is defined as the functional operation of the individual h/w unit in a computer system. Input Unit. In each functional unit, the operation performed is denoted in each block of the diagram. Explain the functional units of a computer with block diagram 2 See answers subhadra53 subhadra53 Answer: A computer can process data, pictures, sound and graphics. performs basically five major computer operations or functions irrespective of their size and make. ii) Output unit. 1 . They can solve highly complicated problems quickly and accurately. CPU: Central Processing Unit CU: Control Unit. Black lines indicate data flow, whereas red lines indicate control flow. Input devices are used to interact with a computer system or used enter data and instructions to the computer. It represents the fundamental building block of the central processing unit (CPU) of a computer. Functional Units 2. Software functional and performance specifications for compound elements of the software functional configuration. A computer as shown in Fig. Input Unit A computer must receive both data and program statements to … The functional hierarchy diagrams present the levels of functional breakdown of functional requirements to components and units. What is Digital Computer? The set of instruction is in the form of raw data. The main function of input devices is to direct commands and data into computers. The ALU performs the actual numerical and logic operation such as ‘add’, ‘subtract’, ‘AND’, ‘OR’ etc. Sent to the computer case, computer chassis, or computer tower the supplied data the supplied data Variable Static.
