ROM is an acronym for Read Only Memory. ROM is a type of computer memory that can only be read and not written to. It contains permanent data that is stored during manufacturing and cannot be modified or erased by normal computer operations. This type of memory is used to store firmware and other essential programs that are required for the computer to boot up and perform basic functions.

The correct answer is "a set of program instructions and data that allow the processor to communicate with other hardware components." BIOS, or Basic Input/Output System, is a firmware that is stored on a motherboard and is responsible for initializing and testing hardware components during the boot process. It provides the necessary instructions for the processor to communicate with devices such as the hard drive, memory, and other peripherals.

PCI-Express is the correct answer because it is the current standard for connecting modern graphics cards. PCI-Express provides a higher bandwidth and faster data transfer rates compared to older standards like ISA, EISA, and PCI. Therefore, PCI-Express is the preferred choice for connecting contemporary graphics cards to the motherboard.

Hyper-Threading is the correct answer because it refers to the parallelism technique that allows a processor to execute multiple threads simultaneously. It enables a single physical core to function as multiple logical cores, improving overall performance and efficiency. This technology is commonly found in Intel processors and helps to optimize multitasking and workload management.

The correct answer is L1 cache. L1 cache refers to the first level of cache memory that is integrated within the CPU. It is the closest and fastest memory to the CPU, designed to store frequently accessed data and instructions to improve overall system performance. This cache is smaller in size compared to higher level caches but has the lowest latency, making it ideal for storing critical data that needs to be accessed quickly.

The correct answer is 4.7 GB. This is the capacity of a single side single layer DVD disk.

The correct answer is L1, L2, L3. This is because L1 cache is the fastest and closest to the CPU, followed by L2 cache, and then L3 cache. The closer the cache is to the CPU, the faster it can retrieve data, which is why L1 cache is the fastest. L2 cache is larger than L1 cache but slower, and L3 cache is even larger but slower than both L1 and L2 cache. Therefore, the order of the levels of cache from fastest to slowest is L1, L2, L3.

The correct answer is PCI-Express. PCI-Express is the most common type of universal expansion slots for modern PC computers. These slots are used to connect various types of expansion cards, such as graphics cards, sound cards, and network cards, to the motherboard of the computer. PCI-Express provides faster data transfer rates compared to older slot types like ISA, EISA, and AGP, making it the preferred choice for modern computer systems.

The correct answer is CHIPSET. The chipset is a set of electronic components that manages the flow of data between the CPU, memory, and other peripherals. It is typically located near the CPU on the motherboard. The other options, EU, IU, and AU, are not commonly used terms in relation to computer components.

The correct answer is RJ 45. RJ 45 is the standard connector used for Ethernet networking. It is commonly used for connecting computers, routers, switches, and other network devices to create a local area network (LAN). The RJ 45 connector has eight pins and is designed to be used with twisted pair cables. It is larger in size compared to the RJ 11 connector, which is used for telephone connections. RS 232 and Contronix are not commonly used connectors for network cards.

The ATX 12V connector is used to provide power to the processor. This connector ensures that the processor receives the necessary power supply to function properly. Without this connector, the processor would not be able to operate efficiently or at all. The other components listed, such as the HD, ventilator, and CD drive, may require power as well, but they typically have their own separate power connectors. Therefore, the correct answer is the processor.

SSD diskovi imaju manje vreme pristupa podacima u odnosu na klasične HD diskove. This means that SSD disks have faster data access times compared to traditional HD disks.

The CPU's clock speed is determined by the multiplier and the bus frequency. In this case, the bus frequency is given as 400MHz and the multiplier is given as 8. To calculate the CPU's clock speed, we multiply the bus frequency by the multiplier. Therefore, the CPU's clock speed is 400MHz * 8 = 3200MHz, which is equivalent to 3.2GHz.

The correct answer is 20 pinova. The ATX power connector is a type of power supply connector used in computer motherboards. It typically has 20 pins, which provide power to various components of the motherboard. This connector is designed to ensure proper power distribution and compatibility with the motherboard.

The correct answer is SATA. SATA (Serial Advanced Technology Attachment) is the interface used to connect modern HDDs (Hard Disk Drives). It is a high-speed serial interface that allows for faster data transfer rates and is commonly used in desktop computers, laptops, and external hard drives. SATA replaced the older interfaces such as EISA, ISA, and AGP, which were used in older computer systems.

DRAM memory loses charge over time, causing data to be lost. The process of restoring the charge and preventing data loss is called refreshing. This involves reading and rewriting the data in the memory cells to maintain their charge. Pipelining refers to a technique used in computer processors to optimize instruction execution. Virtual memory management is a technique used by operating systems to allocate and manage memory. Memory extension refers to increasing the amount of memory available in a system.

DDR (Double Data Rate) is the correct answer because it is a type of memory commonly used in quad-core processor systems. DDR memory allows for faster data transfer rates compared to older memory types, making it suitable for high-performance processors. RDRAM, BEDO, and VCM are not commonly used in quad-core processor systems, making them incorrect choices.

The correct answer is "aktivna." In the context of operating systems, the term "aktivna" refers to the active partition from which the operating system is booted. This means that the active partition contains the necessary files and data for the operating system to start up and run. The other options, "extended," "volume boot sector," and "MBR," do not accurately describe the partition from which the operating system is booted.

The correct answer is "lane." In the context of serial data transmission over the PCIe bus, a "lane" refers to a single differential pair of wires that carries data in one direction. The PCIe bus consists of multiple lanes, with each lane capable of transmitting data at high speeds. Therefore, the term "lane" accurately describes the path for serial data transmission over the PCIe bus.

The correct answer is northbridge. The northbridge chip enables the interaction between the CPU and RAM. It is responsible for managing the high-speed communication between the CPU, RAM, and other high-performance components. The northbridge chip also controls the data flow between the CPU and the graphics card.

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.

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.

The correct answer is "DDR3 i DDR2 imaju konektore sa po 240 pinova". This statement correctly states that both DDR3 and DDR2 have connectors with 240 pins.

The correct answer is "potrebe za osvežavanjem" (need for refreshing). DRAM memory is slower than SRAM memory because it requires constant refreshing to maintain the stored data. This refreshing process adds an overhead and slows down the overall performance of the DRAM memory.

The correct answer is 80 because the ATA interface connector has a total of 80 pins. This connector is commonly used for connecting storage devices such as hard drives and optical drives to the motherboard of a computer. The large number of pins allows for the transfer of data and power between the storage device and the motherboard.

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.

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.

The correct answer is "jedino ograničenje je broj konektora na matičnoj ploči" which means the only limitation is the number of connectors on the motherboard. This suggests that the maximum number of SATA devices that can exist on a computer depends on the number of available connectors on the motherboard.

The correct answer is "ograničen broj upisa" which translates to "limited number of writes" in English. This means that one disadvantage of SSD (Solid State Drive) compared to traditional HD (Hard Drive) is that SSDs have a limited number of write cycles. This means that over time, the SSD may become less reliable and may need to be replaced sooner than a traditional HD.

BIOS (Basic Input/Output System) je odgovor koji je tačan. BIOS je firmware koji se nalazi na matičnoj ploči računara i čuva osnovne informacije neophodne za podizanje računara, kao što su postavke hardvera, informacije o uređajima i prva instrukcija koju računar izvršava pri pokretanju. RAM (Random Access Memory) je vrsta memorije koja se koristi za trenutno čuvanje podataka i izvršavanje programa, ali ne sadrži osnovne informacije o podizanju računara. DDR3 i SDRAM su vrste RAM memorije, ali ne čuvaju osnovne podatke za podizanje računara.

The correct answer is "koji omogućava interakciju CPU i periferija." This answer states that the Južni most (South Bridge) is part of a chipset that allows interaction between the CPU and peripherals. This suggests that the South Bridge is responsible for facilitating communication between the CPU and various peripheral devices connected to the computer, such as USB ports, audio devices, and network interfaces.

SDRAM (Synchronous Dynamic Random-Access Memory) is the correct answer because it is a type of DRAM memory that is synchronized with the system clock. This means that data transfers between the memory and the processor occur in sync with the system clock, allowing for faster and more efficient data access. SDRAM is commonly used in computers and other electronic devices due to its high speed and performance capabilities.

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 correct answer is "basic disk i dynamic disk". This is because basic disk and dynamic disk are two methods used for partitioning a hard disk. A basic disk is the traditional disk type that supports primary partitions, extended partitions, and logical drives, while a dynamic disk is a newer disk type that allows for more advanced features such as creating volumes that span multiple disks. Therefore, basic disk and dynamic disk are the correct options for partitioning a hard disk.

The NTC resistor in the base of the CPU is used for measuring temperature.

The correct answer is "gustina staza*linearna gustina." This is because the total data density on a hard disk is calculated by multiplying the track density (gustina staza) with the linear density (linearna gustina). This calculation takes into account the number of tracks and the length of each track to determine the overall data density on the hard disk.

AGP je skraćenica za Accelerated Graphic Port i predstavlja priključak na PCI magistralu. AGP je posebna vrsta priključka na matičnoj ploči koja je bila namijenjena isključivo za grafičke kartice. AGP je bio razvijen kako bi omogućio brži protok podataka između grafičke kartice i ostalih dijelova računala, što je rezultiralo poboljšanom grafikom i performansama u igrama i drugim grafički intenzivnim zadacima.

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.

The correct answer is 650 nm. This refers to the wavelength of the laser beam used in DVD devices. The wavelength of 650 nm falls within the red portion of the visible light spectrum. DVD players use this specific wavelength because it is ideal for reading the microscopic pits and lands on the surface of a DVD, which contain the encoded data. By using a laser with a wavelength of 650 nm, the DVD player can accurately read the information stored on the disc and play it back accordingly.

The correct answer is 8.5 GB. This is the capacity of a single side double layer DVD disc. It means that the disc can hold up to 8.5 gigabytes of data.

The correct answer is "kratkospojnici na samim disk jedinicama" (jumpers on the disk units). When two disks are connected to the PATA interface, the master and slave units are determined by the jumpers set on the disk units themselves. These jumpers control the device's identification and determine its role in the system.

The correct answer is that the voltage levels provided by the power source are within the acceptable range. This means that the power source is functioning properly and supplying the necessary voltage for the PC to operate.

The correct answer is "which enables the interaction between CPU and RAM." This is because a chipset is a set of electronic components in a computer that manages the data flow between the processor, memory, and other devices. The CPU (central processing unit) and RAM (random access memory) are two crucial components in a computer system, and the chipset facilitates their communication and interaction.

The correct answer is "nadomesta sporost čitanja i pisanja podataka" which translates to "compensates for the slowness of reading and writing data". This means that the cache memory in a CD device helps to overcome the slow speed of reading and writing data by storing frequently accessed data closer to the processor, allowing for faster retrieval and processing.

The content of EEPROM memory can be erased without removing the chip from the motherboard.

The correct answer is 9.4 GB. This is because the capacity of a double side single layer DVD disk is typically 4.7 GB per side. Since it is double sided, the total capacity would be 9.4 GB.

After starting the computer, a procedure is initiated to test individual hardware components. This test is called POST (Power-On Self Test).

An HDD can have up to 4 primary partitions. This means that the hard disk can be divided into 4 separate sections, each of which can be used to store data or install an operating system. Having multiple primary partitions allows for better organization and management of data on the hard drive.

The registers in a CPU are used to temporarily store instructions and data. They act as a small, fast storage location that allows the CPU to quickly access and manipulate the information it needs to perform calculations and execute instructions. By using registers, the CPU can efficiently process data without constantly accessing the slower main memory.
