FTP stands for File Transfer Protocol. This is a standard network protocol used to transfer files from one host to another over a TCP-based network, such as the internet. It provides a simple and efficient way to transfer files, allowing users to upload, download, and manage files on remote servers. The other options, Fast Text Packet, Frequency/Time Processing, and Federal Trade Program, do not accurately represent the abbreviation FTP in the context of computer networking.

A hard drive is an example of a mass-storage device because it is capable of storing large amounts of data. It uses magnetic storage to store and retrieve data, making it suitable for long-term storage. Unlike a microprocessor, which is responsible for executing instructions and performing calculations, a hard drive is used for data storage purposes. A modem, on the other hand, is a device that enables communication between computers over a network. A read-write head is a component of a hard drive that is responsible for reading and writing data to the storage platters.

The correct answer is the speed of an Internet connection. Mbps is a unit used to measure the rate at which data is transmitted over a network or internet connection. It represents the amount of data that can be transferred in one second. This unit is commonly used to describe the speed of internet connections, indicating how quickly data can be downloaded or uploaded. It is not related to the memory capacity of a chip, the storage capacity of an external hard drive, or the image resolution of a printer.

The main microprocessor in a computer is located on the motherboard because the motherboard is the main circuit board that connects all the components of the computer together. The microprocessor, also known as the central processing unit (CPU), is the brain of the computer and performs most of the calculations and operations. It needs to be directly connected to the motherboard to communicate with other components such as memory, storage, and input/output devices. Placing the microprocessor on the motherboard ensures efficient communication and coordination between all the computer's components.

Protocol ensures that computers can exchange data. Protocol refers to a set of rules and guidelines that govern the communication between computers or devices in a network. It establishes the standards for data formatting, transmission, and error handling, allowing different computers to understand and interpret the data being exchanged. Without protocols, computers would not be able to effectively communicate with each other, hindering data exchange and collaboration between devices.

Web page addresses usually begin with the letters "http," which stands for Hypertext Transfer Protocol. This protocol is used for transmitting and receiving information on the internet. It defines how data is formatted and transmitted between web servers and web browsers. Therefore, the correct answer is protocol.

A telephone modem is a device that allows computers to transmit data over telephone lines. It needs to convert analog signals from the telephone line into digital signals that the computer can understand. This is done by an A/D converter, which stands for analog-to-digital converter. The A/D converter takes the analog signals from the telephone line and converts them into digital signals that can be processed by the microprocessor in the modem. Therefore, the correct answer is an A/D converter.

The correct answer is 1024 KB because one megabyte is equal to 1024 kilobytes. The prefix "kilo-" represents a factor of 1000, so 1 kilobyte is 1000 bytes. However, in computing, data is often measured in binary form, where each unit is a power of 2. Therefore, 1 kilobyte is actually 1024 bytes. By extension, 1 megabyte is 1024 kilobytes.

The character string [email protected] is in the format of an email address, with the username "ako" followed by the "@" symbol and the domain name "mabait.com". This format is commonly used to identify and communicate with individuals through email. Therefore, the character string most likely represents an email address.

The correct answer is "a piece of data sent over the Net." This answer is correct because a packet is a unit of data that is transmitted over a network. In computer networking, data is divided into small packets before being sent over the network, and these packets are reassembled at the receiving end to recreate the original data. Therefore, a packet is specifically associated with the process of transmitting data over a network, making this answer the most accurate.

Cross-referencing among web pages is done with hypertext links. Hypertext links are clickable elements on a webpage that allow users to navigate to other webpages or different sections within the same webpage. These links are an essential component of the World Wide Web, enabling the interconnectedness of web pages and facilitating easy access to related information. By clicking on a hypertext link, users can quickly jump to another webpage or location, enhancing the overall browsing experience and providing a seamless way to navigate the vast amount of information available on the internet.

None of the given character strings represents the proper format for an e-mail address. An e-mail address should have the format "[email protected]" or "[email protected]". The given options do not include the "@" symbol or the proper domain format. Therefore, none of the options are correct.

A flash memory module provides the fastest access time among the given options. Flash memory is a type of non-volatile storage that can be electrically erased and reprogrammed. It has no moving parts, which allows for faster data access compared to magnetic tape drives, CD-R or CD-RW drives, and external hard drives. Flash memory also has a high data transfer rate, making it ideal for applications that require quick access to data.

The sharpness of an image on a computer display can be specified in terms of dot pitch. Dot pitch refers to the distance between the individual phosphor dots on a display screen. A smaller dot pitch indicates a higher resolution and sharper image, as the dots are closer together. Refresh rate refers to the number of times the image is refreshed per second, interlace rate refers to the method of displaying images using alternating lines, and wavelength refers to the length of a wave. However, none of these directly relate to the sharpness of the image on a computer display.

A platter is a correct answer because it refers to one of the main components of a hard drive. A hard drive consists of multiple platters, which are circular disks coated with a magnetic material. These platters store the data in the form of magnetic patterns. The read/write heads of the hard drive access and manipulate the data on these platters, making them an essential part of the hard drive's functioning.

The correct answer is low operating cost. This means that using a dot-matrix printer is cost-effective in terms of maintenance and consumables. Unlike other types of printers, dot-matrix printers use inexpensive ink ribbons and have fewer parts that need to be replaced regularly, resulting in lower operating expenses. This makes them a more affordable option for businesses or individuals who print frequently or in large volumes.

A flatbed scanner can be used to scan magazines or books intact because it has a flat surface where the document can be placed. This allows for the entire document to be scanned without the need to separate or manipulate the pages. On the other hand, a feedthrough scanner requires the document to be fed through a small slot, which makes it difficult to scan larger or thicker items like books or magazines without damaging them. Therefore, the advantage of a flatbed scanner over a feedthrough scanner is the ability to scan larger or thicker items without any damage or manipulation.

During 2:00 a.m. local time on a Tuesday, there is likely to be less internet traffic in New York City. This is because most people are asleep at that time, resulting in lower demand for internet usage. With fewer users accessing the web, the network bandwidth is less congested, allowing for faster internet speeds. Hence, the web should be expected to work fastest for a user in New York City at 2:00 a.m. local time on a Tuesday.

A display that does not use interlacing is best suited for animated graphics work involving fast motion, such as high-end gaming. Interlacing is a technique used in some displays where every other line of the image is displayed at a time, which can result in motion blur and reduced image quality. A display that does not use interlacing will provide smoother and clearer animations, making it ideal for fast motion graphics work.

A thermal printer would be an ideal choice for a salesperson who is on the road because it is portable and lightweight. Thermal printers use heat to transfer ink onto paper, eliminating the need for ink cartridges or ribbons. This makes them convenient for mobile use as they require less maintenance and are less bulky compared to other types of printers. Additionally, thermal printers can print quickly, which is beneficial for a salesperson who may need to print documents or receipts on the go.

A magnetic tape is a serial-access medium because it stores data in a linear manner. To access a specific piece of data, the tape must be sequentially read or rewound until the desired location is reached. This makes it a slower medium compared to others listed, such as a diskette, hard drive, or CD-R/CD-RW, which are all random-access mediums that allow for faster and direct access to data.

When computer data is sent over long-distance telephone circuits, it is generally represented by audio tones. These audio tones are used to encode the digital highs and lows of the data. The tones can be of different frequencies and durations, which allows for the transmission of the binary information. This method of representing data is commonly used in technologies such as modems, where the audio tones are converted back into digital data at the receiving end.

The term "cylinder" in this context refers to a set of tracks in a hard drive. In a hard drive, the data is stored on multiple platters, and each platter has multiple tracks. A cylinder is formed by the collection of tracks that are at the same position on each platter. This means that when the read/write head moves to a particular cylinder, it can access the corresponding track on each platter simultaneously. This organization allows for efficient and quick access to data on the hard drive.
