electronic literacy
CONNECTOR: name given to those cables that allow combining two elements.
ELECTRIC POWER: is the flow of charge that flows through a conductor.
AC: (Alternating Current) power supply in which the magnitude and direction vary cyclically.
DC: (Direct Current) is that power flowing steadily in the same direction
GROUNDING: is a ground that is made to electronic equipment to prevent damage in case of dangerous transient current.
STATIC: is a type of power that does not move, ie it always remains in the same place. Appears mainly due to the effect of friction between two bodies.
basic computer
PLATE MOTHER: also called motherboard is the place where they are connected directly to all internal components of computers and as such is the largest component of it.
MICROPROCESSOR: is a small chip whose function is to coordinate, execute and process all actions performed on the computer, is the most important component of it, is called "brain computer", because without this the computer can not work.
RAM: ( Random Access Memory) is working memory in the present tense of the computer, which stores temporary data that you need it to work.
ROM: is Read Only Memory, is called firmware because information that is written in it is recorded permanently and can not be changed.
EXPANSION SLOTS: are electrical connectors or slots in which they introduced to the various expansion cards such as video, audio, network, etc.
• PCI SLOTS: are slots for the interconnection of existing peripheral components, are used for the insertion of all expansion cards except video card 3D.
• AGP SLOT: is an Accelerated Graphics Port, is used exclusively for 3D video cards .
RAM memory slots: As its name implies, are slots which are inserted in the computer's RAM
• SIMM SLOTS: slots are old RAM cards, are short, bring few contacts and all the circuits are attached.
• DIMM SLOTS: are slots for RAM cards and modern, are a bit longer than the SIMM and bring separate circuits.
SOCKET: connector is installed on the motherboard which is installed or set the computer's microprocessor.
CHIPSET: are a set of electronic circuits that handle data transfer between the various components of the computer.
SYSTEM CLOCK: Is one that regulates the speed of execution of the instructions of the microprocessor and the various internal peripherals.
CMOS: also known as cell or battery, works like a small memory that stores some important information such as computer configuration, date, time, etc.
BIOS: ( Basic Input / Output ) is a memory that contains software that allows different basic monitoring work at boot time and equipment: tests video devices, management keyboard, device recognition and load the operating system are some of their routine or main tasks.
INPUT / OUTPUT CONNECTORS: are those which connect the input and output devices to the computer, these are:
- SERIAL PORTS: To connect older devices now rarely used.
- PARALLEL PORTS: For connection of printers.
- Universal Serial Bus (USB) port for connecting devices recent.
- RJ45 CONNECTOR: for connecting the computer network.
- VGA CONNECTOR: to connect the monitor.
- AUDIO CONNECTORS: for connecting speakers, headphones and microphone.
HARD DRIVE: is a device that permanently stores data, this data can be deleted when the user so desires. The basic parts of a disc are:
• Face: each one side of a plate. •
Sector: each of the divisions of a track.
• Cylinder: Joint several tracks. •
Track: A circle within a face. • Plato
: each of the disks inside a hard disk.
OPERATING SYSTEM: is the basic software that controls a computer, on which other applications are installed. Its function is to coordinate and handle all the processes that are carried out internally and organize data or files on storage devices.
UTILITY: are applications or programs whose function is to keep the system optimized and stable.
