Complete Guide on 23 main Types of Computer: Names & Pictures

A computer is a programmed machine that automatically carries out arithmetic and logical operations sequences. Modern digital electronic systems have various capabilities to perform generic operations, known as programs. These applications allow computers to perform multiple functions, such as data storage, retrieval, and processing. Computers are multipurpose machines for document production, email communication, gaming, online surfing, spreadsheet manipulation, presentation development, and video editing. Before seeing different types of computers, it’s necessary to know two essential features of computer systems: hardware and software.

Hardware includes the visible parts of a computer, such as keyboards, CPU, keyboard, mouse, and other inside parts.

Software, on the other hand, is a collection of instructions that direct the hardware of a computer by describing actions and execution methods. Web browsers, gaming, and word-processing apps are examples of software.

Types of Computers based on Data Type


Digital computers are a specific class of machines engineered to tackle problems by manipulating discrete data. They operate within binary code, utilizing just two values: 0 and 1.

These devices often fall into the category of personal computers. Binary input is the exclusive language these computers comprehend, and they translate this binary input to generate corresponding output.

Proficient in different logical and mathematical operations, digital computers exhibit their prowess in handling diverse computational tasks. Regardless of the initial language in which data is presented, these machines mandate the initial translation of all data into binary code before processing.

Typical instances of digital computers encompass laptops, desktop PCs, mobile phones, and analogous gadgets.


An analog computer relies on continual alterations in physical qualities such as electrical, mechanical, or hydraulic quantities known as analog signals. These computers are good at jobs that need data with continuous changes rather than discrete values.

Analog computers are the ideal choice for applications that do not require accurate numerical values, such as monitoring characteristics like speed, temperature, pressure, and current.

Analog computers link directly to sensors or measuring devices, eliminating the need for initial numerical code conversion. They record and evaluate the continuing oscillations in physical parameters, often displaying their output on a dial or scale.

A speedometer or a mercury thermometer can be used to demonstrate the functionality of analog computers.


A hybrid computer combines the strengths of analog and digital computing systems to achieve better performance and versatility. This unique combination allows hybrid computers to execute intricate calculations quickly and efficiently.

These computers receive analog inputs, which are later converted into digital formats for processing, resulting in output generation.

Notably, the scientific community has begun adopting hybrid computing for challenging computational tasks, including monitoring patients’ cardiac rhythms within medical facilities and analyzing seismic data related to earthquakes and other natural phenomena within research institutions.

Types of Computers Based on the Purpose



A microcomputer is a small computer, often called a personal computer (PC) or a single-chip CPU-based device. Its design is suitable for individual use in performing fundamental computing tasks.

It is characterized based on its compact form factor and cost-effectiveness. Microcomputers are very inexpensive and require little space.

Furthermore, there is a fair demand for input and output (I/O) devices. Microcomputers are generally designed to integrate all electronic components onto a single printed circuit board (PCB). Microcomputers include tablets, iPads, smartwatches, laptops, and desktop computers.

A minicomputer is a compact computing device using one or more processors to execute tasks. These machines have limited expandability processing power and RAM storage, falling middle to microcomputers and mainframe computers in the computing order.

The primary objective of minicomputers is to provide individuals with efficient computing capabilities without accessing a central mainframe system.

Their applications include controlling manufacturing processes, business transactions, and scientific and laboratory experiments, including processing the resultant data.

Moreover, minicomputers serve as valuable assets in networking by functioning as servers. It helps ease the workload of primary servers and acts as front-end processors for larger mainframe computers.

These devices also suit tasks like file management, database administration, engineering calculations, and creative domains such as entertainment and design work.



Mainframes are powerful computing machines characterized by their high memory capacity and multiple data processors. These computers are good at managing large-scale, straightforward calculations and real-time transactions.

Mainframe computers are pivotal in supporting critical commercial databases, transaction servers, and applications that require exceptional resilience, top-tier security, and adaptability.

Mainframe computers are significant but are less extensive than the supercomputer. However, they have high processing power compared to various other computer categories, including minicomputers, servers, workstations, and personal computers, when it comes to processing capabilities.



Supercomputers are powerful machines in the industry of computational technology. The parts of supercomputers are I/O systems, interconnects, memory units, and processor cores. It has more processing power than regular computers due to having more central processing units (CPUs).

These CPUs are grouped into computing nodes, each of which houses a processor or a group of processors that use symmetric multiprocessing (SMP) methods in collaboration with dedicated memory resources.

Supercomputers can comprise tens of thousands of such nodes on a large scale. These nodes work collaboratively to solve complicated challenges. Furthermore, the interconnect architecture creates communication links with I/O systems like data storage and networking, improving their overall functionality.

Types of Computers Based on the Functionality



Workstations are specialized computer systems designed to meet the refined technological requirements of a wide range of power users. These systems promote superior performance, data integrity, dependability, and administration simplicity.

Unlike regular personal computers, workstations are generally designed for single-user operation while smoothly connected to a local area network and equipped with multi-user operating systems.

Historically, “workstation” referred to a wide range of devices, from mainframe computer terminals to network-connected desktop computers. A workstation is distinguished by its toughness. It has a fast microprocessor, a large amount of RAM, and an innovative graphics card to provide more excellent processing capabilities.



A server is a software program or hardware device responsible for delivering a specific service to another program or its end-users, often referred to as the client. Within the infrastructure of a data center, the physical computing device on which a server program operates is frequently denoted as the server itself.

Servers are designed to offer diverse services, which include sharing data or resources among multiple clients, executing complex computations on behalf of a client, or fulfilling a range of specialized tasks.

Remarkably, a single server can cater to multiple clients; conversely, a single client can engage with numerous servers. The client process may either run on the same device as the server or establish a network connection to interact with a server situated on a different device.

Common examples of servers include database servers, file servers, mail servers, print servers, web servers, game servers, and application servers.


Embedded Computers

An embedded computer, often called an embedded PC, represents a specialized computing system with an essential component of a more extensive, interconnected apparatus or system.

Unlike a conventional desktop computer, an embedded computer is tailored and designated for a singular, well-defined purpose. It is seamlessly integrated within a comprehensive device, often encompassing electrical or electronic components and mechanical elements.

Given its primary role in governing the physical operations of the host machine, an embedded system frequently encounters real-time computational constraints. Embedded systems exert command over an array of widely adopted devices.
