Computer Technology Quiz: Memory And Hard Drives

The correct answer is DARPA- Defense Advanced Research Projects Agency. The internet, as we know it today, developed from the research and development projects funded by DARPA. In the late 1960s, DARPA funded the creation of ARPANET, which was the first network to use packet switching to transmit data. This laid the foundation for the development of the internet. DARPA continued to support and fund various projects that contributed to the growth and expansion of the internet, making it the global network that it is today.

The hard disk drive stores data on the magnetic surface of the platter. The platter is a circular disk made of a magnetic material coated with a thin layer of magnetic material. It is where the data is written and read from using the read/write heads. The platter spins at a high speed while the read/write heads move across its surface to access and store data. Therefore, the platter is an essential component of the hard disk drive for data storage.

Ram stands for Random Access Memory, which is a form of volatile memory. Volatile memory means that its contents are lost when the power is turned off or lost. Therefore, Ram is not a form of memory that is non-volatile.

Data that is deleted from a hard disk is not completely gone and can often be retrieved using specialized software or techniques. When data is deleted, it is typically marked as "deleted" or "free space" in the file system, but the actual data remains on the disk until it is overwritten by new data. Therefore, it is possible to recover deleted data unless it has been overwritten.

The given statement is false. The Hard Disk Drive (HDD) is a form of non-volatile memory, meaning that it retains data even when the power is turned off. Unlike volatile memory, such as Random Access Memory (RAM), which loses its data when the power is disconnected, the HDD stores data magnetically on spinning disks and is able to retain it for long periods of time.

The correct answer is TCP/IP. TCP/IP (Transmission Control Protocol/Internet Protocol) is the protocol used on the internet for packet switching. It is a set of rules that governs how data is transmitted and received over the internet. TCP ensures reliable delivery of data by dividing it into packets and reassembling them at the destination, while IP handles the addressing and routing of these packets across different networks. TCP/IP is the foundation of the internet and allows for seamless communication between devices connected to the network.

Level 1 Cache is located inside the processor. It is a small, high-speed memory that stores frequently accessed data and instructions. It helps in reducing the time it takes for the processor to access data from the main memory. The Level 1 Cache is the closest and fastest cache to the processor, providing quick access to frequently used data, which improves the overall performance of the processor.

The first network refers to the earliest form of communication network, and in this case, it is the Telegraph. The Telegraph was invented in the early 19th century and revolutionized long-distance communication by transmitting electrical signals over wires. It allowed messages to be sent and received almost instantly, making it the precursor to modern telecommunications systems. While the internet, pony express, and Cray super computer are all significant advancements in communication and computing, they came into existence much later than the Telegraph.

The correct answer is "Cache, Ram, Rom" because these three types of memory are commonly found in computer systems. Cache memory is a small, high-speed memory that stores frequently accessed data for faster retrieval. RAM (Random Access Memory) is the main memory of a computer, used for temporarily storing data that the CPU (Central Processing Unit) needs to access quickly. ROM (Read-Only Memory) is a type of memory that stores permanent instructions and data that cannot be modified. Together, these three types of memory play crucial roles in the functioning of a computer system.

The North Bridge is responsible for connecting the RAM and the Processor Cache. It acts as a bridge between the CPU and the memory, allowing data to be transferred between them. The North Bridge handles high-speed communication between the CPU and the RAM, ensuring efficient data transfer. Therefore, the correct answer is North Bridge.
