Software:
It is known as software [1] the logical or support of a digital computer LOGICAL; includes all necessary software components that make possible the realization of specific tasks, as opposed to physical components of the system, called hardware.
These logical components include, among many other computer applications? As the word processor that allows the user to perform all tasks related to the editing of texts? or the system software? such as operating system, which basically allows the other programs work properly, facilitating interaction with physical components and other applications, also providing an interface for the user?.
Random Access Memory (RAM)
There’s too much "stuff" on your computer’s hard disk to use it all at the same time. During the average session sitting at the computer, you’ll probably use only a small amount of all that’s available. The stuff you’re working with at any given moment is stored in random access memory (often abbreviated RAM, and often called simply "memory"). The advantage using RAM to store whatever you’re working on at the moment is that RAM is very fast. Much faster than any disk. For you, "fast" translates to less time waiting and more time being productive.
So if RAM is so fast, why not put everything in it? Why have hard disks at all? The answer to that lies in the fact that RAM is volatile. As soon as the computer is shut off, whether intentionally or by an accidental power outage, everything in RAM disappears, just as quickly as a light bulb goes out when the plug is pulled. So you don’t want to
Database
A database is a "store" that allows us to store large amounts of information in an organized manner so that we can then easily find and use. Here’s a guide that will explain the concept and characteristics of the databases.
The term database was first heard in 1963 at a symposium in California, USA. A database can be defined as a set of related information that is grouped or structured.
From the point of view, the database is a system consisting of a set of data stored on disks that allow direct access to them and a set of programs that manipulate the data set.
Each database consists of one or more tables that store a set of data. Each table has one or more columns and rows. The columns bear a part of the information on each item you want to save in the table; each table row constitutes a record.
Circuit
A circuit is a power supply (interconnection of two or more components such as resistors, inductors, capacitors, sources, switches and semiconductor containing at least one closed path.
Circuits containing only sources, linear components (resistors, capacitors, inductors), and linear distribution elements (transmission lines or cables) can be analyzed by algebraic methods to determine their behavior in direct current or alternating current
A circuit having electronic components is called an electronic circuit. These networks are generally nonlinear and require design and analysis tools more complex
Operating system:
Operating System (OS) is the basic software of a computer that provides an interface between the other computer programs, hardware devices and the user.
The basic functions of the OS are managing machine resources, coordinate the hardware and organize files and directories on storage devices.
The most widely used operating systems are DOS, Windows, Linux and Mac OS Some come with an integrated browser, such as Windows that brings the Internet Explorer browser.
