computer can be defined as an electronic device, which manipulates data or information and has the capability and ability to process, store, and retrieve data. It can be used for document typing, internet searching, surfing, and emailing. Computer can also be used in handling accounting, spreadsheets, database management, games, and presentations. The development and production of the present-day computer is credited to the result of advances and progress in technologies and need for quantification. Abacus, which was one of the first counting machines, paved the way for the production and manufacture of computer .
In recent years customers have more alternative options to the Personal Computer such as Laptops, Tablet, etc. Because of the availability and thinness of these items, they have become increasingly popular and making PC more obsolete. In order for the personal computer to compete with these newer alternative options, it must differentiate itself in order to regain market share.
Suppliers: Bargaining Power of Suppliers: Low Suppliers in the personal computer industry can be categorized into three groups:
· Hardware suppliers
· Software suppliers
· Service suppliers
Generally their products are standardized and these companies compete on better price on new products and also they attempt to differentiate by these items. So all companies in this industry can easily switch their suppliers. The main part of the PC is Microprocessor which shows the quality of PC and all software which can install on it. Thus suppliers of hardware and software in this industry play a critical role in the pricing of products.
PC is a compact computer that uses a microprocessor and is designed for individual use, as by a person in an office or at home or school, for such applications as word processing, data management, financial analysis, or computer games. Abbreviation: PC.
A personal computer (PC) is a multi-purpose computer whose size, capabilities, and price make it feasible for individual use. Personal computers are intended to be operated directly by an end user, rather than by a computer expert or technician. Unlike large, costly minicomputers and mainframes, time-sharing by many people at the same time is not used with personal computers.
Institutional or corporate computer owners in the 1960s had to write their own programs to do any useful work with the machines. While personal computer users may develop their own applications, usually these systems run commercial software, free-of-charge software ("freeware"), which is most often proprietary, or free and open-source software, which is provided in "ready-to-run", or binary, form. Software for personal computers is typically developed and distributed independently from the hardware or operating system manufacturers. Many personal computer users no longer need to write their own programs to make any use of a personal computer, although end-user programming is still feasible. This contrasts with mobile systems, where software is often available only through a manufacturer-supported channel, and end-user program development may be discouraged by lack of support by the manufacturer.
Since the early 1990s, Microsoft operating systems and Intel hardware dominated much of the personal computer market, first with MS-DOS and then with Microsoft Windows. Alternatives to Microsoft's Windows operating systems occupy a minority share of the industry. These include Apple's macOS and free and open-source Unix-like operating systems, such as Linux.
Before the widespread use of PCs, a computer that could fit on a desk was remarkably small, leading to the "desktop" nomenclature. More recently, the phrase usually indicates a particular style of computer case. Desktop computers come in a variety of styles ranging from large vertical tower cases to small models which can be tucked behind or rest directly beneath (and support) LCD monitors.
While the term "desktop" often refers to a computer with a vertically aligned computer tower case, these varieties often rest on the ground or underneath desks. Despite this seeming contradiction, the term "desktop" does typically refer to these vertical tower cases as well as the horizontally aligned models which are designed to literally rest on top of desks and are therefore more appropriate to the "desktop" term, although both types qualify for this "desktop" label in most practical situations aside from certain physical arrangement differences. Both styles of these computer cases hold the systems hardware components such as the motherboard, processor chip, other internal operating parts. Desktop computers have an external monitor with a display screen and an external keyboard, which are plugged into ports on the back of the computer case. Desktop computers are popular for home and business computing applications as they leave space on the desk for multiple monitors.
