Unix definition

Multiplatform, multi-tasking and multi-user operating system originally developed by Bell employees of AT&T.

UNIX can now refer to: * UNIX family: generic group of operating systems that share certain criteria in their design and are therefore called from the family (or type) UNIX.They are more than 100 operating systems that are considered of their family.

* UNIX operating system: subfamily of operating systems that descend from the first version created by Bell.This means that they share codes and intellectual property.

* UNIX Brand: Unix as a brand is owned by "The Open Group", a standardization organization that allows the use of that brand to any operating system that meets its standards.This is independent of whether the operating system in question is from the UNIX family or descended from the original.

Definition of Macrocomputer (macrocomputer)

A macrocomputer is a large, powerful and expensive computer used primarily in companies that need to process large amounts of data or support large numbers of users.It contrasts with the concept of microcomputer (or microcomputer).Sometimes called macrocomputers. In English: mainframe and macrocomputer. For more information see: Mainframe What is a macrocomputer or mainframe? A large and powerful computer capable of managing a large number of simultaneous tasks and of communicating with a large number of connected terminals; used by large and complex organizations (such as banks and supermarkets) in which continuous operation is vital. Characteristics of macromputers Macrocomputers are a type of computer that are generally known Due to their large size, storage quantity, processing power and high level of reliability, they are mainly used by large organizations for critical mission applications that require large volumes of data processing.In general, there are some characte...

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...

Floppy disk drive definition

The floppy disk drive is a physical device or drive that is responsible for reading/writing to floppy disks.In English, floppy disk drive (FDD) or floppy disk drive. In IBM PCs, they are used to write or read on floppy disks.5 1/4 or 3 1/2 inches.They are usually represented with the A: or B units: They are removable storage devices. The floppy drives were invented by the IBM company, being the versions of 8, 5¼ and 3½ inches (and all its variants) the most popular forms for the storage and exchange of data from the mid-70s to the end of the 90s.Computers gradually stopped bringing floppy drives, being replaced by readers of optical disks (CDs, DVDs...), flash memories, external hard drives, etc. Operation of the floppy drives Basically the floppy drives have a small motor that rotates a floppy disk at a controlled speed, while a second engine operates a mechanism that moves a Magnetic read-write head on the surface thereof.Both read and write operations require the head to ph...

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...

Definition of Cognitive Computing (CC)

Cognitive computing (CC) describes technology platforms that, in general terms, are based on the scientific disciplines of artificial intelligence and signal processing.These platforms cover machine learning, reasoning, natural language processing, voice recognition and vision (object recognition), man-machine interaction, dialogue and narrative generation, among other technologies. At present, there is no widely accepted definition of cognitive computing. In general, the term computation Cognitive has been used to refer to new hardware and/or software that mimics the functioning of the human brain and helps to improve people's decision-making.In this sense, CC is a new type of informatics with the aim of obtaining more models precise how the human brain/mind detects, reasons and responds to the stimulus. Uses of Cognitive Computing -Voice Recognition -Analis is of feelings -Face detection -Risk assessment -Fraud detection -Behavioral recommendations Characteristics of...

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 ...
