The speed, power and flexibility of computers are increasing dramatically ever since then, with junction transistor counts increasing at a fast pace (as foretold by Moore’s law), resulting in the Digital Revolution throughout the late twentieth to early twenty first centuries.

Central Process Unit (CPU)

Conventionally, a contemporary laptop consists of a minimum of one process part, generally a central process unit (CPU) within the kind of a silicon chip, at the side of some sort of computer storage, generally semiconductor memory chips. The process part carries out arithmetic and logical operations, and a sequencing and management unit will amendment the order of operations in response to keep data. Peripheral devices embody input devices (keyboards, mice, joystick, etc.), output devices (monitor screens, printers, etc.), and input/output devices that perform each functions (e.g., the 2000s-era touchscreen). Peripheral devices permit data to be retrieved from Associate in Nursing external supply and that they modify the results of operations to be saved and retrieved.

What are the types of computer?

A computer System is a device that transforms data into the meaningful information. It processes the input according to the set of instructions provided to it by the user and gives the desired outputs. Computers are of various types and they can be categorized in two ways on the basis of size and on the basis of data’s handling capabilities.

It runs swimmingly for an extended time and contains a long life.

3. Minicomputer:

Minicomputer could be a medium size parallel processing laptop. during this form of laptop, there ar 2 or a lot of processors, and it supports four to two hundred users at only once. Minicomputers ar employed in places like institutes or departments for various work like request, accounting, inventory management etc. it’s smaller than a mainframe however larger as compared to the PC.

Characteristics of minicomputer:

Its weight is low.
Because of its low weight, it’s straightforward to hold anyplace.
less expensive than a mainframe.
It is fast.

4. Workstation:

Workstation is meant for technical or scientific applications. It consists of a quick silicon chip, with an oversized quantity of RAM and high speed graphic adapter. it’s a single-user laptop. It typically accustomed perform a particular task with nice accuracy.

Characteristics of Workstation:

It is pricey or high in value.
They are solely created for complicated work functions.
It provides giant storage capability, with higher graphics, and a a lot of powerful mainframe in comparison to a laptop.
It is conjointly accustomed handle animation, knowledge analysis, CAD, audio and video creation, and writing.

5. laptop (Personal Computer):

It is conjointly called a PC. it’s essentially a all-purpose laptop and designed for individual use. It consists of a silicon chip as a central process unit(CPU), memory, input unit, and output unit. this sort of laptop is appropriate for private work like creating associate degree assignment, observation a motion picture, or at workplace for job work, etc. as an example, Laptops and desktop computers.

Characteristics of laptop (Personal Computer):

In this restricted range of software system will be used.
It is smallest in size.
