Microcomputers include desktop computers, notebook computers or laptops, tablet computers, handheld computers, smartphones, and netbooks, as shown in the figure below.

Here, we summarized the classification of computers by generation as follow: First-generation computers were based on vacuum tubes.

These machines were large in size, expensive to operate and instructions were written in machine language.

They were smaller in size, less expensive and required less maintenance than the first-generation computers.

Third-generation computers were characterized by the use of Integrated Circuits.

They consumed less power and required low maintenance compared to their predecessors.

These computers marked the beginning of commercial production.

Fourth-generation computers used microprocessors which were designed using the LSI (Large Scale Integration) and VLSI (Very Large-Scale Integration) technology.

They became available both to the home user and for commercial use.

Fifth-generation computers are expected to be capable of learning and self-organization.

The computers use SLSI (Super Large-Scale Integration) chips and have large memory requirements.

They use parallel processing and are based on (AI) Artificial Intelligence.

Classification of computers by Types There are three major classification of computers by type, namely: Analog, Digital, and Hybrid computers.

Analog computers are used for measuring parameters that vary continuously in real-time, such as temperature, pressure, and voltage.

Analog computers may be more flexible but generally less precise than digital computers.

In general, analog computers are extraordinarily fast, since they can solve most complex equations at the rate at which a signal traverses the circuit, which is generally an appreciable fraction of the speed of light.

On the other hand, the precision of analog computers is not good; they are limited to three, or at most, four digits of precision.

Hybrid Computer: Hybrid computers are computers that exhibit features of analog computers and digital computers.

The digital component normally serves as the controller and provides logical operations, while the analog component normally serves as a solver of differential equations.

Hybrid computers can be used to obtain a very good but relatively imprecise seed value, using an analog computer front-end, which is then fed into a digital computer iterative process to achieve the final desired degree of precision.

With a three or four-digit, highly accurate numerical seed, the total digital computation time necessary to reach the desired precision is dramatically reduced, since many fewer iterations are required.

Computers are broadly classified into four based on their size, namely.
