o ηλεκτρονικός υπολογιστής είναι μι

o ηλεκτρονικός υπολογιστής είναι μια μηχανή κατασκευασμένη κυρίως από ψηφιακά ηλεκτρονικά κυκλώματα και δευτερευόντως από ηλεκτρικά και μηχανικά συστήματα, και έχει ως σκοπό να επεξεργάζεται πληροφορίες. Ο ηλεκτρονικός υπολογιστής είναι ένα αυτοματοποιημένο, ηλεκτρονικό, ψηφιακό επαναπρο­γραμ­ματιζόμενο σύστημα γενικής χρήσης το οποίο μπορεί να επεξεργάζεται δεδομένα βάσει ενός συνόλου προκαθορισμένων οδηγιών, των εντολών που συνολικά ονομάζονται πρόγραμμα.

Κάθε υπολογιστικό σύστημα, όσο μεγάλο ή μικρό κι αν είναι, αποτελείται από το υλικό μέρος (hardware) και το λογισμικό (software). Τα βασικά στοιχεία του υλικού μέρους του υπολογιστή είναι η κεντρική μονάδα επεξεργασίας (ΚΜΕ, αγγλ. CPU, Central Prossesing Unit), η κεντρική μνήμη (RAM & ROM-BIOS), οι μονάδες εισόδου - εξόδου (πληκτρολόγιο, ποντίκι, οθόνη κ.α.), οι εσωτερικές (ή εξωτερικές) μονάδες ανάγνωσης και αποθήκευσης δεδομένων όπως σκληρός δίσκος, DVD, SSD (Solid State Drive) και οι περιφερειακές συσκευές όπως εκτυπωτής, σαρωτής, μόντεμ κ.α.).

Υπάρχουν διάφοροι τύποι υπολογιστών οι οποίοι διαφέρουν κατά το μέγεθος, τις δυνατότητες (επεξεργαστική ισχύς) και την αρχιτεκτονική τους, δηλαδή τον τρόπο που τα βασικά τους μέρη συνδέονται και συνεργάζονται μεταξύ τους. Στην πιο διαδεδομένη κατηγορία υπολογιστών ανήκουν οι μικροϋπολογιστές. Στους μικροϋπολογιστές τα βασικά εξαρτήματα, όπως ο επεξεργαστής, η μνήμη κ.ά., βρίσκονται τοποθετημένα σ' ένα τυπωμένο κύκλωμα που ονομάζεται μητρική κάρτα (αγγλ. Motherboard ή MoBo). Εκτός από τον επεξεργαστή και τη μνήμη, πάνω στη μητρική βρίσκονται οι θέσεις επέκτασης στις οποίες τοποθετούνται οι διάφορες κάρτες, γραφικών, ήχου κ.λπ.). Στη μητρική επίσης βρίσκονται υποδοχές για τη σύνδεση διαφόρων άλλων συσκευών (όπως ο σκληρός δίσκος, η οπτική μονάδα ανάγνωσης DVD, card reader κλπ), ή και προς επέκταση των ήδη εγκατεστημένων.

Το λογισμικό του υπολογιστή αποτελείται από τα απαραίτητα προγράμματα που δίνουν τις κατάλληλες εντολές, για να λειτουργεί το υλικό μέρος. Συνίσταται δε από το λειτουργικό σύστημα (το βασικό πρόγραμμα για τη λειτουργία του Η/Υ καθώς και για την επικοινωνία του με τον άνθρωπο) και το λογισμικό εφαρμογών (πακέτα εφαρμογών, γλώσσες προγραμματισμού, εκπαιδευτικό λογισμικό, προγράμματα – εργαλεία κ.α.).

o computer is a machine constructed mainly from digital electronics circuits and secondarily by electrical and mechanical systems, and is designed to process information. The computer is an automated, electronic, digital epanaprogrammatizomeno system for general use which can process data based on a set of predefined directives, mandates referred to collectively as the program.Every computer system, no matter how big or small it may be, consists of the hardware (hardware) and the software (software). The key hardware components from your computer's central processing unit (CPU, Eng. Central Unit CPU, Prossesing), the main memory (RAM & ROM-BIOS), input-output units (keyboard, mouse, monitor, etc.), internal (or external) read and data storage drives such as hard disk, DVD, SSD (Solid State Drive) and peripheral devices like printer, scanner, modem, etc.).There are several types of computers that differ in size, the possibilities (processing power) and their architecture, i.e. the way that their essential parts are connected and work together. The most widespread computer class belong the microcomputers. On microcomputers standard accessories, such as the processor, memory, etc., are mounted on a printed circuit called motherboard (Eng. Motherboard or MoBo). Besides the processor and memory, on the motherboard are the places where expansion placed the various cards, graphics, audio, etc.). The parent also are Sockets for connecting various devices (such as hard disk, optical drive DVD reader, card reader etc), or to an extension of the already installed.Computer software consists of basic programs that give appropriate commands to operate the hardware part. Consists of the operating system (the Basic program for the operation of PCs as well as for communication with humans) and software applications (application packages, programming languages, educational software, programs – tools, etc.).

o computer is a machine built mainly of digital electronic circuits and secondarily by electrical and mechanical systems, and is designed to process information. The computer is an automated, electronic, digital reprogrammable universal system that can process data using a set of predefined directives, orders totaling called program. Each computer system, however big or small it is, consists of the hardware part (hardware) and software (software). The basic elements of computer hardware part is the central processing unit (CPU GATE. CPU, Central Prossesing Unit), the main memory (RAM & ROM-BIOS), the input units - output (keyboard, mouse, screen, etc. .), the internal (or external) readers and data storage such as hard disk, DVD, SSD (Solid State Drive), and peripherals such as printer, scanner, modem, etc.). There are different types of computers that differ size, capabilities (processing power) and their architecture, ie how the key parts are connected and work together. In the most widespread computer category are microcomputers. In microcomputers key components, such as processor, memory, etc., are mounted on a printed circuit board called the motherboard (in English. Motherboard or MoBo). Apart from the processor and memory, on the motherboard are expansion spaces are located in which various cards are placed, graphics, audio, etc.). At parent are also jacks for connecting various other devices (such as hard disk, optical reader DVD, card reader, etc.) or to expand already installed. The computer software consists of the necessary programs that give the appropriate commands , to operate the hardware part. Not recommended by the operating system (the main program on the operation of H / PC and for communication with man) and application software (application packages, programming languages, educational software programs - tools etc).
