Cum se numeste memoria nevolatila inclusa in sistem ? (How is the permanent memory built into your computer called?)
- A.
ROM
- B.
Cache
- C.
RAM
- D.
CPU
Correct Answer
A. ROMExplanation
ROM stands for Read-Only Memory. It is a type of non-volatile memory that is built into a computer system. Unlike RAM, which is volatile and loses its data when the power is turned off, ROM retains its data even when the power is off. ROM is used to store firmware and other permanent instructions that are essential for the computer to boot up and operate. Therefore, ROM is the correct answer to the question.Rate this question:

Care dintre urmatoarele nu reprezinta un dispozitiv periferic de iesire ? (Which of the following is not an output device?)
- A.
Monitorul (monitor)
- B.
Imprimanta (printer)
- C.
Boxele audio (speakers)
- D.
Tastatura (keyboard)
Correct Answer
D. Tastatura (keyboard)Explanation
The keyboard is not an output device because it is used for inputting data into a computer rather than displaying or producing output. It is used for typing and entering commands, allowing the user to interact with the computer and control its functions. Output devices, on the other hand, are used to display or produce information from the computer, such as monitors for displaying visuals, printers for producing hard copies of documents, and speakers for playing audio.Rate this question:

- A.
Tastatura, mouse, scanner
- B.
Mouse, imprimanta, joystick
- C.
Microfon, mouse, joystick
- D.
Tastatura, mouse, trackball
Correct Answer
B. Mouse, imprimanta, joystickExplanation
The correct answer is "mouse, imprimanta, joystick". A mouse and a joystick are both input devices as they allow users to interact with a computer by providing input. An imprimanta (printer) is an output device as it produces output in the form of printed documents. Therefore, the mouse, imprimanta, and joystick are not input devices.Rate this question:

Unui computer ii pot atasa oricata memorie RAM
- A.
Adevarat
- B.
Fals
Correct Answer
B. FalsExplanation
The statement "Unui computer ii pot atasa oricata memorie RAM" translates to "A computer can have as much RAM attached to it." This statement is false because there is a limit to the amount of RAM that a computer can support. Each computer has a maximum limit of RAM that it can handle, and exceeding this limit can cause compatibility issues or system instability. Therefore, it is not true that a computer can have an unlimited amount of RAM attached to it.Rate this question:

- D.
Read Agree Messages
Correct Answer
B. Random Access MemoryExplanation
RAM stands for Random Access Memory, which is a type of computer memory that allows data to be read or written in almost the same amount of time regardless of the physical location of data inside the memory. It is a volatile memory, meaning it loses its stored information when the power is turned off or interrupted. RAM is an essential component of a computer system as it provides temporary storage for data and instructions that are actively being used by the CPU.Rate this question:

Care dintre urmatoarele reprezinta un slot de expansiune ?
- A.
PCI
- B.
HDD
- C.
CPU
- D.
USB
Correct Answer
A. PCIExplanation
PCI (Peripheral Component Interconnect) este un slot de expansiune care permite conectarea de plăci de extensie la placa de bază a unui computer. Aceste plăci de extensie pot adăuga funcționalități suplimentare, cum ar fi plăci de rețea, plăci de sunet sau plăci video. Prin urmare, PCI este un slot de expansiune, în timp ce HDD (Hard Disk Drive), CPU (Central Processing Unit) și USB (Universal Serial Bus) nu sunt sloturi de expansiune.Rate this question:

Placa de baza este componenta fizica ce reprezinta Unitatea Centrala de Prelucrare
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
The given statement is incorrect. "Placa de baza" in Romanian translates to "motherboard" in English, not "Unitatea Centrala de Prelucrare" which means "Central Processing Unit" (CPU). The motherboard is a physical component that connects various hardware components of a computer, including the CPU. Therefore, the correct answer is False.Rate this question:

1 KB=1000 Bytes
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
The statement "1 KB=1000 Bytes" is incorrect. In the context of computer storage, 1 KB (kilobyte) is equal to 1024 bytes, not 1000 bytes. This is because computers use a binary system, where each unit is a power of 2. Therefore, the correct answer is False.Rate this question:

Numarul 5 poate fi scris in baza 2 ca 101
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
The statement is true because the number 5 can indeed be written in base 2 as 101. In base 2, also known as the binary system, there are only two digits available, 0 and 1. Each digit represents a power of 2, starting from the rightmost digit. So, 101 in base 2 translates to (1 * 2^2) + (0 * 2^1) + (1 * 2^0) = 4 + 0 + 1 = 5. Therefore, the answer is true.Rate this question:

- C.
Dimensiunea memoriei de lucru
- D.
Latimea de banda a procesorului
Correct Answer
A. Capacitatea de stocare a harddiskuluiExplanation
Capacitatea de stocare a harddiskului nu influențează performanțele unui PC deoarece aceasta se referă doar la spațiul disponibil pentru stocarea datelor, nu la viteza de procesare a acestora. Performanțele unui PC sunt influențate de frecvența microprocesorului, dimensiunea memoriei de lucru și lățimea de bandă a procesorului, deoarece acestea afectează viteza de calcul și transferul de date în sistemul computerului.Rate this question:

Suportul pe care microprocesorul se conecteaza pe placa de baza se numeste
Correct Answer
socketExplanation
The correct answer is "socket" because a socket is the interface that allows a microprocessor to connect to the motherboard. It provides a physical and electrical connection between the processor and the motherboard, allowing them to communicate and work together effectively. Without a socket, the processor would not be able to connect to the motherboard and function properly.Rate this question:

- D.
Adresele paginilor web recent accesate
Correct Answer
C. Datele inscripționate în aceastaExplanation
After shutting down the computer, the ROM memory will retain the data that has been written or inscribed into it. This means that any information that has been stored in the ROM will remain intact even when the computer is powered off. ROM is a type of non-volatile memory, which means that it retains its data even without power. Therefore, the correct answer is that the ROM memory will retain the data inscribed into it.Rate this question:
