What is microcomputer and block diagram?
A microcomputer is a computer built on the basis of a microprocessor i.e. a processor implemented as an integrated circuit. A more developed block diagram of a microcomputer is shown in the figure below. Besides RAM and ROM memories, more input/output units are connected to the microprocessor.
What is Micro computer with diagram?
A digital computer with one microprocessor which acts as a CPU is called microcomputer….Table: Important Intel Microprocessors.

What are the basic blocks of microcomputer?
A microcomputer has three basic blocks: a central processing unit (CPU), a memory unit, and an input/output (I/O) unit.
What is the function of microcomputer?
Microcomputer was formerly a commonly used term for personal computers, particularly any of a class of small digital computers whose CPU is contained on a single integrated semiconductor chip. Thus, a microcomputer uses a single microprocessor for its CPU, which performs all logic and arithmetic operations.
What are the four building blocks of a microcomputer system?
It consists of four basic elements: the CPU (central proces sing unit), the ROM (read only memory), the RAM (random access memory), and the SR (shift register).
What are the primary function of CPU of microcomputer?
A central processing unit (CPU), also called a central processor, main processor or just processor, is the electronic circuitry that executes instructions comprising a computer program. The CPU performs basic arithmetic, logic, controlling, and input/output (I/O) operations specified by the instructions in the program.
What are the characteristics of microcomputer?
The essential characteristics of these microcomputers are:
- Small size and low cost.
- One user.
- Easy to use.
- Low computing power.
- Commonly used for personal application.
What is a block diagram in geology?
A block diagram is a sketch of a relief model—in particular, a representation of a landscape in a perspective projection. The need for these pseudo-three-dimensional diagrams is, according to Lawrence (1971), often encountered in the interpretation of landforms.
What is operating system and its function?
An operating system (OS) is a program that acts as an interface between the system hardware and the user. Moreover, it handles all the interactions between the software and the hardware. Further, it performs all the functions like handling memory, processes, the interaction between hardware and software, etc.
