    O operație care NU face parte dintre funcțiile unui sistem de operare este gestionarea:

    • Mesajelor trimise prin e-mail

    • Proceselor

    • Resurselor hardware

    • Resurselor software

    Correct Answer
    A. Mesajelor trimise prin e-mail
    Explanation
    The correct answer is "mesajelor trimise prin e-mail". This is because managing messages sent through email is not a function typically performed by an operating system. The functions of an operating system generally include managing processes, hardware resources, and software resources. However, the management of email messages is usually handled by specific email client software or email servers, rather than the operating system itself.

    O acțiune realizată prin serviciul de comerț electronic (e-commerce) poate fi:

    • Cumpărarea online a unei biciclete

    • Plata on-line a impozitelor

    • Primirea unui e-mail

    • Traducerea online a unui text

    Correct Answer
    A. Cumpărarea online a unei biciclete
    Explanation
    The correct answer is "cumpărarea online a unei biciclete" because it is the only option that directly relates to an action performed through e-commerce. The other options, such as paying taxes online, receiving an email, or translating a text online, are not specific to e-commerce and can be done through other means as well.

    The correct answer is "tastatura" (keyboard). A keyboard is an essential input device for a personal computer. It allows users to input text and commands into the computer. Without a keyboard, it would be difficult to interact with the computer and perform various tasks. Therefore, a keyboard is a necessary component in the minimum configuration of a personal computer.

    • Bit pe secundă

    • Byte (octet)

    • Pitch (punct)

    • Pixel

    Correct Answer
    A. Byte (octet)
    Explanation
    The correct answer is byte (octet). In computer memory, data is addressed and stored at the level of a byte, which is a unit of digital information that consists of 8 bits. Each byte can represent a character or a number, and it is the fundamental unit of storage in most computer systems.

    Indicați dispozitivul a cărui principală caracteristică tehnică este numărul de instrucțiuni executate în unitatea de timp:

    • Modemul

    • Monitorul

    • Placa de bază

    • Procesorul

    Correct Answer
    A. Procesorul
    Explanation
    The correct answer is "procesorul". The main technical characteristic of a processor is the number of instructions it can execute in a given unit of time. The processor is responsible for carrying out all the calculations and operations in a computer system, making it a crucial component for the overall performance of the system. The other options listed, such as modemul, monitorul, and placa de bază, do not directly relate to the number of instructions executed in a unit of time.

    • Ofere informații cu caracter personal

    • Viziteze anumite site-uri

    Correct Answer
    A. Raporteze mesajul la un serviciu online specializat (Spam Alert)
    Explanation
    An unsolicited email (spam) does not aim to make the recipient report the message to a specialized online service (Spam Alert). Spam emails typically have the objective of promoting certain services or products, gathering personal information, or directing the recipient to specific websites.

    Dintre următoarele dispozitive de stocare, cea mai mare viteză de acces la date o are dispozitivul:

    • CD

    • DVD

    • Hard disk

    • Memorie flash

    Correct Answer
    A. Hard disk
    Explanation
    The hard disk has the highest data access speed among the given storage devices. This is because hard disks use magnetic storage technology, which allows for faster read and write operations compared to other devices like CDs, DVDs, and flash memory. Hard disks have spinning platters and read/write heads that can quickly access data from different locations on the disk. On the other hand, CDs and DVDs have slower access speeds because they rely on optical technology, while flash memory has limited access speed due to its architecture. Therefore, the hard disk is the correct answer for the device with the highest data access speed.

    Într-un sistem de calcul, gestionarea resurselor hardware este asigurată de:

    • Hard drive

    • Sistemul de operare

    • Suprafața de lucru (Desktop)

    • Unitatea centrală de prelucrare

    Correct Answer
    A. Sistemul de operare
    Explanation
    Într-un sistem de calcul, gestionarea resurselor hardware, cum ar fi procesorul, memoria și dispozitivele de stocare, este asigurată de sistemul de operare. Sistemul de operare este software-ul care controlează și coordonează toate operațiunile și resursele hardware ale unui computer. El permite utilizatorilor să interacționeze cu computerul și să ruleze diverse aplicații. Deci, sistemul de operare este responsabil de gestionarea și controlul resurselor hardware dintr-un sistem de calcul.

    Transmiterea datelor între componentele unui calculator se realizează prin intermediul:

    • Rețelei de calculatoare

    • Mouse-ului

    • Modemului

    • Magistralei de date

    Correct Answer
    A. Magistralei de date
    Explanation
    The correct answer is "magistralei de date" (data bus). This is because the data transfer between the components of a computer is typically done through the data bus, which is a communication pathway that allows for the transfer of data between the CPU, memory, and other peripheral devices. The data bus acts as a central highway through which information is transmitted, allowing for efficient communication and coordination between different parts of the computer system.
