1.7. The Types Of PC/Es And Their Characteristics

PCs can be comprehensively ordered by their speed and processing power.

PC (Personal Computer)

A PC (Personal Computer) can be characterized as a little, generally cheap PC intended for a singular client. Laptops depend on the microchip innovation that empowers producers to put a whole CPU on one chip. PCs are utilized in business areas for word handling, bookkeeping, work area distributing, and for running calculation sheet and data set administration applications. At home, the most well known use for PCs is messing around and riding the Internet. The qualities of personal computer are
  • PCs used to be enormous and would at some point occupy the entire room of a room.
  • These PCs were modest and reasonable for people in general.
  • Work station typically have a different screen, console, mouse, speakers and so forth.
  • Can be utilized as an independent PC in your home for individual or work use.
  • Will in general be associated with own printer and web association.


Laptop Computer, known as note pads, are compact PCs that you can take with you where as you like and use in various conditions. They incorporate a screen, console, and a trackpad or trackball, which fills in as the mouse. Since workstations are intended to be utilized in a hurry, they have a battery which permits them to work without being connected to an electrical plug. PC of the relative multitude of parts (screen, console and so forth) are together on a solitary gadget. The fundamental benefits of a PCs they are versatile and they can interface remotely to organize associations.


A Notebook PC is a battery – or AC-fueled PC for the most part more modest than a portfolio that can undoubtedly be moved and helpfully utilized in impermanent spaces like on planes, in libraries, transitory workplaces, and at gatherings. A journal PC, in some cases called a PC, weighs under 5 pounds and is 3 inches or less in thickness. Among the most popular creators of note pad and PCs IBM, Apple, Compaq, Dell, Toshiba, and Hewlett-Packard. A sequential port likewise permits a normal mouse to be joined. The PC Card is embed capable equipment for adding a modem or organization interface card to a note pad. CDROM and advanced flexible circle drives might be underlying or connectable.


A palmtop PC is a PC or other electronic gadget that has a significant number of similar highlights as a PC and fits in the center of your hand. A genuine illustration of an early palmtop PC is the PalmPilot. Due to their size, early palmtop PCs didn’t have a console or a mouse and frequently depended on a pen that pre-owned Graffiti or something almost identical. The expression “palmtop PC” was an early term utilized when PCs were huge and unwieldy and little cells and even cell phones were not yet imagined. Today, this term is seldom used to depict a PC that fits in your grasp as a result of the development of the cell phone.


Workstation is a PC utilized for designing applications (CAD/CAM), work area distributing, programming improvement, and other such sorts of utilizations which require a moderate measure of processing power and generally top notch illustrations capacities. Workstations for the most part accompanied a huge, high-goal designs screen, enormous measure of RAM, inbuilt organization support, and a graphical UI. Most workstations likewise have mass capacity gadget, for example, a circle drive, yet an extraordinary sort of workstation, called diskless workstation, comes without a plate drive. Normal working frameworks for workstations are UNIX and Windows NT. Like PC, workstations are additionally single-client PCs however are commonly connected together to shape a neighborhood despite the fact that they can likewise be utilized as independent frameworks.


  • A PC is an electronic information handling gadget, which acknowledges and stores information input, processes the information input, and produces the result in a necessary configuration.
  • Abacus was the main including gadget which was created in China over a long time back.
  • Napier’s bone is a gadget which contains a bunch of bars made of bones. It was created by John Napier in 1617, a Scottish Mathematician.
  • Slide Rule was a simple gadget developed by William Oughtred in 1620. The slide rule is utilized for the most part for augmentation and division, and furthermore for “logical” works like roots, logarithms and geometry, however typically not really for expansion or deduction. The slide rule depends on the work on logarithm.
  • Pascaline is a working out machine created by Blaise Pascal in 1642, a French Mathematician. It was the main gadget with a capacity to perform increases and deductions on entire numbers.
  • Stepped Reckoner a working out machine planned in (1671) and worked in (1673) by the German mathematician-savant Gottfried Wilhelm von Leibniz.
  • Jacquard Loom is a connection for fueled looms that utilizes a chain of punch cards to teach the loom on the best way to make many-sided materials. It was developed by Joseph Jacquard and first exhibited in 1801.
  • The insightful motor depended on info, cycle and result standard since the cutting edge PCs depend on Babbage’s thought and guideline. In this manner, Charles Babbage is otherwise called the dad of current software engineering.
  • The Hollerith organizing machine, otherwise called the arranging machine, was an electrical counting machine designed by Herman Hollerith.
  • Mark I was planned (1937) by a Harvard graduate understudy, Howard H. Aiken to take care of cutting edge numerical material science issues experienced in his examination. Aiken’s aggressive proposition imagined the utilization of changed, financially accessible innovations facilitated by a focal control framework.
  • Atanasoff-Berry Computer, (ABC) is considered as the principal electronic advanced PC and was the main machine to utilize vacuum tubes (more than 300 vacuum tubes).
  • Electronic Numerical Integrator and Calculator (ENIAC) was the principal electronic PC utilized for general purposes, like tackling mathematical issues.
  • Electronic Delay Storage Automatic Calculator (EDSAC) is an early British PC viewed as the principal put away program electronic PC.
  • The UNIVAC is an electrical PC containing great many vacuum tubes, uses punch cards and switches for contributing information and punch cards for yielding and putting away information.
  • Communication is a method for passing on a message, a thought, an image, or discourse that is gotten and seen obviously and accurately by the individual for whom it is implied.
  • A Special Purpose PC is planned exclusively to meet the necessities of a specific undertaking or application.
  • A General PC are intended to address the issues of a wide range of utilizations. In these PCs, the directions expected to play out a specific errand are wired forever into the inner memory.
  • An Analog PC is a type of PC that utilizes the persistently inconsistent parts of actual peculiarities, for example, electrical, mechanical, orhydraulic amounts to show the issue being tackled.
  • Digital Computers work basically by counting. All amounts are communicated as discrete or numbers.
  • Hybrid Computers:- will be PCs that display highlights of simple PCs and computerized PCs.
  • A microcomputer is the littlest universally useful handling framework.
  • A minicomputer is a medium-sized PC. That is more impressive than a microcomputer.
  • PCs with enormous capacity limits and exceptionally rapid of handling (contrasted with small scale or microcomputers) are known as centralized server PCs.
  • Supercomputers have incredibly huge capacity limit and registering speeds which are commonly quicker than different PCs.
  • PC age is the order of PCs into various gatherings as per their assembling date, other equipment and programming innovation utilized inside those PCs.
  • The PCs of First Generation utilized vacuum tubes as the fundamental parts for memory and hardware for CPU (Central Processing Unit).
  • PCs of Fourth Generation utilized Very Large Scale Integrated (VLSI) circuits.
  • A PC(Personal Computer) can be characterized as a little, somewhat economical PC intended for a singular client.
  • A Notebook PC is a battery-or AC-fueled PC by and large more modest than a folder case it can undoubtedly be moved and helpfully utilized in brief spaces like on planes, in libraries, transitory workplaces, and at gatherings.
  • A palmtop PC is a PC or other electronic gadget that has a large number of similar highlights as a PC and fits in the center of your hand.    
  • Workstation is a PC utilized for designing applications (CAD/CAM), work area distributing, programming improvement, and other such kinds of uses which require a moderate measure of registering power and generally great illustrations capacities.
