Osnovni razlog zbog kojeg je DDR2 RAM potencijalno brži od DDR RAM-a je:
Correct Answer
D. Povećana je radna frekvencija kod DDR2 RAM-a
Explanation
DDR2 RAM has a higher operating frequency compared to DDR RAM, which makes it potentially faster. This means that DDR2 RAM can transfer data at a higher rate, allowing for quicker input and output operations. The increased working frequency of DDR2 RAM contributes to its potential speed advantage over DDR RAM.
32.
Koji tip memorije mora da se osvežava da bi sačuvao sadržaj
Correct Answer
A. SDRAM
Explanation
SDRAM stands for Synchronous Dynamic Random Access Memory. It is a type of memory that needs to be refreshed periodically in order to maintain its stored data. This is because SDRAM uses capacitors to store data, and over time, the charge in these capacitors leaks away. Therefore, the memory controller needs to constantly refresh the data in SDRAM to prevent data loss.
33.
SSD tipovi diska za brži pristup koriste
Correct Answer
A. DRAM memorije
Explanation
SSD (Solid State Drive) diskovi koriste DRAM (Dynamic Random Access Memory) memorije za brži pristup podacima. DRAM je vrsta memorije koja omogućava brzo čitanje i pisanje podataka. Uz to, DRAM memorija je volatilna, što znači da se podaci gube kada se napajanje isključi. SSD diskovi koriste DRAM memoriju kao keš memoriju za privremeno skladištenje podataka koji se često koriste, kako bi se smanjilo vrijeme pristupa podacima i poboljšala brzina rada diska.

38.
Registri unutar CPU predstavljaju
Correct Answer
A. Memoriju sa brzim pristupom
Explanation
The correct answer is "memoriju sa brzim pristupom". CPU registers are small areas of memory located within the CPU that provide fast access to data and instructions. They store temporary values and operands that are frequently used by the CPU during its operations. Registers have very fast access times compared to main memory, allowing the CPU to quickly retrieve and manipulate data. Therefore, registers can be considered as a form of memory with fast access.
39.
CPU ima radni takt od 2 GHz a magistrala od 266 MHz. Koliki je mnozilac?
Correct Answer
A. 7.5
Explanation
The CPU has a clock speed of 2 GHz (gigahertz) and a bus speed of 266 MHz (megahertz). The multiplier is determined by dividing the clock speed by the bus speed. In this case, 2 GHz divided by 266 MHz equals 7.5. Therefore, the multiplier is 7.5.

Neke CPU mogu da izvrsavaju vise instrukcija istovremeno. Ovo je omguceno
Correct Answer
A. Primenom pipeline tehnologije
Explanation
Some CPUs can execute multiple instructions simultaneously, and this is made possible by implementing pipeline technology. Pipeline technology allows the CPU to divide the execution of instructions into multiple stages, with each stage handling a specific task. This enables the CPU to overlap the execution of multiple instructions and improve overall performance. By breaking down the instruction execution process into smaller tasks and executing them concurrently, the CPU can achieve higher efficiency and throughput.
42.
Pipeline tehnologija omogucava
Correct Answer
A. Istovremeno izvrsavanje veceg broja instrukcija
Explanation
Pipeline tehnologija omogućava istovremeno izvršavanje većeg broja instrukcija. Ova tehnologija omogućava da se instrukcije procesora izvršavaju u paralelnim fazama, što rezultira bržim izvršavanjem instrukcija. Umjesto da se instrukcije izvršavaju jedna po jedna, pipeline tehnologija omogućava da se nekoliko instrukcija izvršava istovremeno, smanjujući vrijeme izvršavanja programa. Ova tehnologija je posebno korisna za procesore s visokim radnim taktom, jer omogućava efikasnije korištenje resursa procesora.
43.

The external data bus is responsible for carrying data between the CPU and other devices such as memory, input/output devices, and peripherals. It allows for the exchange of information and instructions, enabling the CPU to communicate and interact with other components effectively.
46.
Koja je najveća dozvoljena duzina internog SATA kabla(priblizno)?
Correct Answer
A. 0.5 metara
Explanation
The correct answer is 0.5 metara. The maximum allowed length for an internal SATA cable is approximately 0.5 meters. This limitation is due to the signal degradation that can occur over longer cable lengths, which can result in data transmission errors. Therefore, it is important to keep the cable length within this range to ensure optimal performance and reliability of the SATA connection.
47.
Nedostatak SSD u odnosu na klasični HDD je
Correct Answer
A. Ograničen broj upisa
Explanation
The correct answer is "ograničen broj upisa" (limited number of writes). This means that one disadvantage of SSD compared to traditional HDD is that SSDs have a limited number of times that data can be written to them before they start to degrade. This is known as the "write endurance" of the SSD. In contrast, traditional HDDs do not have this limitation and can be written to an unlimited number of times.

The SCSI interface supports parallel data transfer.
49.
Dve faze za pripremu HDD za rad su
Correct Answer
A. Particionisanje i formatiranje
Explanation
The correct answer is "particionisanje i formatiranje." This is because when preparing a HDD for use, the first step is to partition it, which involves dividing the disk into separate sections. This allows for better organization and management of data. The next step is to format the partitioned sections, which involves setting up the file system and structure on the disk. This prepares the HDD to store and retrieve data efficiently.
50.
RAID 1 predstavlja povezivanje diskova na takav način da se
Correct Answer
A. Isti podaci zapisuju na više diskova
Explanation
RAID 1 is a method of connecting disks in such a way that the same data is written to multiple disks. This means that the data is duplicated across the disks, providing redundancy and ensuring that if one disk fails, the data can still be accessed from the other disks. This increases data reliability and availability as well as providing some level of fault tolerance.
