Types of Computers Based on Data Handling Capabilities

Based on the data type handling, computers can be categorized as Digital, Analog, and Hybrid.

Digital

Personal computers are an example of a digital computer. These computers accept input in the form of 0s and 1s. The computer processes binary input and provides the output. These computers perform all the logical & arithmetical operations. Any input given in any language is first converted into binary language and then the computer processes the information. Examples – laptops, PCs, mobile phones, desktops, etc.

Analog

These computers process analog data. Analog data keep varying. Hence, it does not have any discrete value. They read the continuous change in the input, process it, and then provide the output. Analog computers perform with equal diligence and accuracy. They are however slower than digital computers. They are also slightly less precise.
Analog computers are for a Speedometer, thermometer, frequency, and signal of voltage, measuring the resistance of a capacitor.

Hybrid

Hybrid computers are a mix of both analog and digital computers. These computers perform a high level of calculations. Hybrid computers are quick and efficient. They take input in analog form, convert it into digital form, and then process it to produce an output. scientists are also using hybrid computers for complex calculations. For example, in hospitals to measure the heartbeat of the patients, and at research institutes to measure earthquakes and other natural calamities.

Types of Computers Based on Size

Based on the purpose of a computer we can classify the types of computing devices as micro, mainframe, super and mini computers.

Microcomputer

Microcomputers are nothing but personal computers. These are single-chip systems. These are useful for personal use and can perform all the basic functions of the computer. Microcomputers require very little space and are comparatively inexpensive. Such computers have the most minimalistic requirement in terms of I/O devices. And have all the circuitry mounted on a single PCB. For example tablets, I pads, smartwatches, laptops, desktops

Minicomputer

Standing in between a microcomputer and a mainframe computer is the minicomputer. These computers are useful if people around 5 to 300. Those who want to operate the system at the same time. You can see such computers at the billing counters of malls or large institutions.

Mainframe

Mainframe computers are useful when a large number of people are involved. Like in the health care or retail sector who want to access data simultaneously. These computers process large amounts of data.

In addition, mainframe computers have evolved a lot over the years in terms of speed, size, and efficiency. These computers are just below the supercomputers. And sometimes are even more useful than a supercomputer. Examples – IBM z Series, System z9, etc.

Supercomputers

The biggest and fastest computers are supercomputers. Such computers can process trillions of functions within a few seconds. We generally use MPIS( Million Instructions Per Second) to measure their performance. These computers are specifically designed for scientific applications such as –

1. Encryption decryption of passwords
2. Weather forecasting
3. Testing of nuclear weapons
4. Scientific research of earth and other planetary systems, etc.

Examples – PARAM supercomputer series, Gravity Pipe for astrophysics, Deep Crack for deciphering codes, etc.

Types of Computers Based on the Functionality

Workstations

Workstation computers are for single usage and professional purposes. These are like our basic laptops and desktops but with added superior features. For example, double-processor motherboard, added graphic card, ECC RAM, etc. The workstations are more powerful as compared to generic PCs. These can handle heavy-duty functions. Like animation, CAD, audio & video editing, professional gaming, etc.
Examples: Apple PowerBook G4, SPARC CPU, MIPS CPU, etc.

Servers

These are hardware components or software programs that are built to assist other computers termed as clients. Together this architecture is called the client-server model. The client sends a request to the server and the server responds in return with a result or a solution. This proves that these server computers are more powerful than standard computers. The main purpose of these computers is to share data and resources with other computers.
Different types of servers are useful for different needs and applications. For example, cloud server, application server, database server, file server, etc. Each of these servers has a different purpose for different client needs.

Embedded

These computers are mainly microcontroller-based systems. Used for processing specific tasks. Embedded computers have a combination of software and hardware components. But, are usually a part of a larger system. Each of its components is designed from scratch to serve a specific purpose or complete a specific task. Another characteristic that distinguishes them from a standard PC is that all of its components are integrated into a single PCB or motherboard. They are most helpful for industrial use. this is because of their ruggedness.
Examples: GPS systems, centralized heating systems, fitness trackers, digital watches, electronic calculators, etc.

Information appliances

Mostly portable devices designed for specific functions come under this category. They can perform very restricted tasks for which they are built like text editors, music players, photography, videography, etc. The most common example is mobile phones. Many wearable devices are also available in the market.

This completes our article on the different types of computers. To sum up, it can be said that there is everything for everyone.
