Definition of desktop computer (desktop computer)

The desktop computer is a type of computer of adequate size to be used on an office or home desk.

This classification serves to distinguish them from portable computers such as notebooks or PDAs, or larger computers, such as mainframes.

It is also called: desktop computer or desktop computer, in Spain.

These computers cannot easily move from your location and usually require a support desk.The most typical configuration of a desktop computer is: cabinet, monitor, keyboard, mouse and some peripherals as a printer.Currently all-in-one that combine the cabinet and flat screen monitor, making them a bit more portable.

Desktop computers became very popular in the 1980s and 1990s, used both in offices and at home.They began their decline in 2000 by replacing more portable devices such as notebooks, tablets and smartphones s.

Components of a desktop computer

The components of a computer can be basically divided into two:

-Hardware

-Software

• See: Components of a computer (computer)

• See: Computer peripherals

History of desktop computers

The first computers had the size of an entire room, of course they could not be classified as "desktop." Then came the minicomputers, the size of a refrigerator, some offices of large companies had these computers.

In the 60s there were programmable computers/calculators, such as Programma 101 (1965), of the size of a typewriter, which fit on a desk.

In the 70s they were also introduced other models that could be programmed in BASIC.These were small versions of minicomputers that had a small LED display of a line that showed alphanumeric characters.ian graphics using a plotter.

It was really in the 1980s where desktop computers were they became the dominant type, the most popular being the IBM PCs, followed by the Apple Macintosh and the Commodore Amiga (the latter declining its popularity in the early 1990s).

The first desktop computers, such as IBM Personal Computer of 1981, were encapsulated in a cabinet that fit perfectly on a desk, oriented horizontally and with the CRT screen on top of them.

By the 1990s, desktop computers became increasingly accessible and the monitor cabinet was separated.In this case the cabinet (the vertical tower cabinet began to come) could be located on the floor under the desk.They were increasingly powerful, the monitors d and more inches and even the flat LCD monitors were coming.

The laptops of the moment were too expensive and their LCD monitor had a very short viewing angle.

By the middle of In the decade of 2000, laptops began to become very popular and the purchase of desktop computers began to decline.

In 2007, 109 million notebooks were sold, a 33% increase over the previous year In 2008 there were 145.9 million notebooks, in 2009 it amounted to 177.7 million.The third quarter of 2008 was the first time in history that more notebooks were sold than desktop computers worldwide (38.6 million notebooks vs.38.5 million PCs.) The trend continues to increase.

Some analysts suggest that desktop sales were closely related to the Windows operating system.Versions considered "bad" Windows, they were going to lower sales of these computers, probably because people did not feel the need to change/update them.Windows Vista and Windows 8 are the clearest examples of this phenomenon.

The declining trend in desktop sales is also due to a replacement of these with other more portable and more personal devices such as notebooks, netbooks, tablets and smartphones.

All-in-One Computers

iMac, all-in one

All-in-one computers (all in one), which groups the monitor with the processing cabinet, already existed in the early 1980s, such as the Kaypro II, Osborne 1, TRS-80 Model II and Compaq Portable.Both the Commodore and Atari included the computer motherboard on the keyboard, and usually they were connected to a television.I also made several all-in-one models, such as the original Macintosh from the mid-80s and the iMac in the late 1990s and early 2000s.

By the beginning of 2000, most all-in-one computers used a flat screen and began to include multi-touch screens.

In general, both all-in-one and notebooks are more complicated than extend or customize components compared to classic desktop computers.

Definition of DPI or PPP (print quality)

(dots per inch, dots per inch).The DPI or PPP is a unit of measurement of the resolution of an image (related to quality) of a scanner, a printer, etc.It serves to measure the resolution, which is the amount of dots that enter an inch.It is expressed like this: (number) x (number) dpi. A resolution of 300 dpi will produce a text that will show broken lines visible under a magnifying glass.Even larger resolutions are necessary to obtain reproductions of smooth photographs.Professional graphics use printers with resolutions from 1200 to 2400 dpi. Pixels or resolution of a photo and printing in centimeters There is no direct equivalence between the pixels of a digital image and the centimeter of printing that correspond to it.A very small image can be printed very large on paper, but the pixels of the printed image will begin to be noticed at first glance.There are techniques to "enlarge" the digital image and soften it a bit the pixels, but these do not make ma ravillas. ...

Monoprogramming Definition

Monoprogramming, also called monoexecution, is an operating system in which only one program is executed at a time and no other is executed until the previous one is finished. In other words, only one program is executed at a time within a single address space. This type of execution practically does not exist anymore because it has been replaced by multiprogramming. Monoprogramming vs.multiprogramming In the monoprogramming, the memory only contains one program at any time, while in the multiprogramming the memory contains more than one user program. In the case of monoprogramming, when the CPU is running the program and it find an I/O operation (input-output), then the program goes to the I/O devices, during that time the CPU remains idle.Therefore, in the monogramming the CPU is not used effectively, that is, CPU utilization is poor. However, in the multiprog branch, when a user program contains I/O operations, the CPU changes to the next user program.Therefore, the CPU i...

Network transparency definition

Network transparency refers to the ability of a protocol to transmit data over the network in a way that is transparent (invisible) to those who are using the applications that use the protocol.In this regard, users of a particular application they can access remote resources in the same way they would access their own local resources. An example of this is cloud storage, where remote files are presented as if they were locally accessible; also the cloud computing where the resource in question is the processing. From English: network transparency. X Windows The term is often applied partially correctly in the context of the X Windows system, which is capable of transmitting graphic data over the network and integrating it seamlessly with the applications that are running and displayed locally; however, certain extensions of the X Windows system are not able to work on the network. Firewall In firewall technology, transparency can be defined in the network layer ( or IP) or ...

Web Proxy Definition

A web proxy is used to intercept the navigation of web pages for reasons of security, anonymity, performance, etc. A web proxy can be accessed by an IP address, free or paid, which is added to a browser (also There are proxy programs to avoid the configuration process.) When someone uses the browser, everything that is done in it first goes through the proxy first (the proxy server).That is, if a web page is requested the remote proxy will It is in charge of looking for it and sending it to our computer.In this intermediate step the proxy can be used to: * Anonymous browsing: if the proxy is configured in this way, anyone who navigates through that proxy will do so Anonymously, the destination pages will not be able to know the IP address (identification) of the computer you are browsing; they will only see the IP address of the proxy.If a proxy is not configured to be anonymous it is said to be transparent browsing. * Safe browsing: a proxy is responsible for filtering or alertin...
