Microprocesorul are rolul de a:
-
Controla activitatea altor echipamente si de a prelucra informatiile
-
Stocheaza informațiile pe termen lung
-
Executa programele
Correct Answer
A. Controla activitatea altor echipamente si de a prelucra informatiileExplanation
The correct answer is "controla activitatea altor echipamente si de a prelucra informatiile." A microprocessor is responsible for controlling the activity of other equipment and processing information. It acts as the central processing unit (CPU) of a computer system, executing instructions and performing calculations. Additionally, it communicates with other hardware components, such as memory and input/output devices, to coordinate and control their operations.Rate this question:

Informațiile din memoria RAM se pierd la închiderea calculatorului?
-
DA
-
NU
Correct Answer
A. DAExplanation
The answer is "DA" because the information stored in RAM (Random Access Memory) is volatile, meaning it requires a constant supply of power to retain data. When the computer is shut down or loses power, the data stored in RAM is lost. This is why it is important to save any important files or data to a non-volatile storage device, such as a hard drive, before shutting down the computer.Rate this question:

Poate fi șters conținutul memoriei ROM?
-
True
-
False
Correct Answer
A. FalseExplanation
The content of ROM (Read-Only Memory) cannot be erased or modified. ROM is a type of non-volatile memory that is programmed during manufacturing and retains its data even when the power is turned off. Therefore, the statement "Poate fi șters conținutul memoriei ROM?" (Can the content of ROM be erased?) is false.Rate this question:

Unitatea de măsură a HDD este:
-
Ns
-
Gb
-
Hz
Correct Answer
A. GbExplanation
The correct answer is Gb. Gb stands for gigabyte, which is a unit of measurement for digital storage capacity. HDD, or hard disk drive, is a type of computer storage device that uses magnetic storage to store and retrieve digital information. The capacity of an HDD is typically measured in gigabytes (Gb), which indicates the amount of data that can be stored on the drive. Therefore, Gb is the appropriate unit of measurement for HDDs.Rate this question:

Care este unitatea elementară de măsură a informației?
Correct Answer
bitulExplanation
The correct answer is "bitul." A bit is the fundamental unit of information in computing and digital communications. It represents a binary digit, which can have two possible values: 0 or 1. Information is stored and transmitted in the form of bits, and they are used to measure the amount of data or information in a system. Therefore, the bit is considered the elementary unit of measurement for information.Rate this question:

Monitorul este caracterizat de :
-
Numărul maxim de culori
-
Rezoluția
-
Nivelul de radiații
-
Claritatea imaginii
Correct Answer(s)
A. Numărul maxim de culori
A. Rezoluția
A. Nivelul de radiații
A. Claritatea imaginiiExplanation
The correct answer includes all the characteristics that define a monitor. The number of colors refers to the maximum number of different colors that the monitor can display, which affects the quality and realism of the images. The resolution refers to the number of pixels that the monitor can display, determining the level of detail and sharpness of the images. The level of radiation refers to the amount of electromagnetic radiation emitted by the monitor, which can have health implications. Lastly, the clarity of the image refers to how sharp and clear the displayed content appears on the monitor.Rate this question:

Care este diferența dintre CD-ROM și CD-R/RW ?
-
CD-ROM citește informațiile, iar CD-R / RW citește, scrie și rescrie informațiile
-
CD-ROM inscripționează informațiile, iar CD-R / RW citește informațiile
Correct Answer
A. CD-ROM citește informațiile, iar CD-R / RW citește, scrie și rescrie informațiileExplanation
CD-ROM is a type of compact disc that can only read information, while CD-R/RW can read, write, and rewrite information. Therefore, the correct answer is that CD-ROM only reads information, while CD-R/RW can read, write, and rewrite information.Rate this question:

Memoria ROM este folosită pentru:
-
Citire - scriere
-
Scriere
-
Citire
Correct Answer
A. CitireExplanation
Memoria ROM este utilizată doar pentru citire. Acest tip de memorie este non-volatilă, ceea ce înseamnă că datele stocate în ea nu se pierd atunci când alimentarea este întreruptă. Deoarece datele sunt scrise permanent în timpul fabricației, utilizatorii nu pot scrie sau modifica datele stocate în memoria ROM. Prin urmare, răspunsul corect este "citire".Rate this question:

Un megaoctet (Mo ) are.................kiloocteți (ko).
Correct Answer
1024Explanation
One megabyte (Mo) is equal to 1024 kilobytes (ko). This is because in digital systems, data is often represented in binary form, and 1024 is the closest power of 2 to 1000. Therefore, when converting between megabytes and kilobytes, we use the factor of 1024.Rate this question:

La care dintre tehnologiile de monitoare de mai jos se regăsește cea mai mare rezoluție și paletă de culori?
-
XGA
-
VGA
-
SVGA
-
CRT
Correct Answer
A. SVGAExplanation
SVGA (Super Video Graphics Array) is the correct answer because it offers a higher resolution and color palette compared to the other options listed. XGA (Extended Graphics Array) has a lower resolution than SVGA, VGA (Video Graphics Array) has an even lower resolution than XGA, and CRT (Cathode Ray Tube) refers to a type of monitor technology rather than a specific resolution or color palette. Therefore, SVGA is the technology that provides the highest resolution and color options among the given choices.Rate this question:

Memoria internă
Correct Answer(s)
A. Microprocesorul
A. Memoria internăExplanation
The correct answer is microprocesorul, memoria internă. On the motherboard, the microprocessor and internal memory are connected. The microprocessor is the central processing unit of the computer, responsible for executing instructions and performing calculations. The internal memory refers to the storage space within the computer, where data and instructions are temporarily stored for quick access by the microprocessor. These components are essential for the functioning of the computer system.Rate this question:

La care dintre următoarele periferice viteza de lucru se măsoară în caractere pe secundă (cps)?
-
Procesor
-
Imprimantă
-
Tastatură
-
Disc dur
Correct Answer
A. ImprimantăExplanation
Perifericele care măsoară viteza de lucru în caractere pe secundă (cps) sunt dispozitivele de intrare/ieșire care permit introducerea și afișarea de caractere. Procesorul este componenta centrală a unui sistem de calcul și nu măsoară viteza de lucru în cps. Tastatura și discul dur sunt dispozitive de intrare/ieșire care permit introducerea și stocarea de date, dar nu măsoară viteza de lucru în cps. În schimb, imprimanta este un dispozitiv de ieșire care tipărește caractere pe hârtie și, prin urmare, măsoară viteza de lucru în cps.Rate this question:

Ordonați crescător următoarele unități d emăsură a capacității de memorare: Go, To, Ko, o, Mo, Eo.
Correct Answer
o, Ko, Mo, Go, To, EoExplanation
The given answer arranges the units of memory capacity in ascending order. Starting with the smallest unit "o" (which represents octet), it is followed by "Ko" (kilooctet), "Mo" (megaoctet), "Go" (gigaoctet), "To" (teraoctet), and finally "Eo" (exaoctet), which is the largest unit.Rate this question:
