Computer And Media Studies: Quiz 3 '10

RAM is like short term memory because it is used for temporary storage of data that is actively being used by the computer. It allows for quick access and retrieval of information, similar to how short term memory allows us to remember things temporarily. On the other hand, ROM is like long term memory because it stores permanent instructions and data that are essential for the computer's operation. It is non-volatile memory, meaning the data stored in it remains even when the computer is turned off, just like our long term memory retains information for a longer period of time.

This statement is true because on average, a minute of MP3 audio is compressed to about 1 megabyte (MB) of file size. The compression algorithm used in MP3 format reduces the file size by removing some of the audio data that is less perceptible to the human ear. Therefore, it is possible to store approximately 1 minute of MP3 audio in a file that is around 1 megabyte in size.

LAN stands for Local Area Network. A Local Area Network refers to a network that connects computers and other devices within a limited area, such as a home, office, or building. It allows for the sharing of resources, such as files and printers, and enables communication between devices on the network. "Learn About Nematodes," "Large Actual Numbers," and "Large Amphitheater Network" are not relevant or accurate definitions for LAN.

ROM, or Read-Only Memory, is a type of computer memory that stores information that is not meant to be changed or modified. It is used to store infrequently changing data such as saved files and programs that are not currently being used. Unlike other types of memory, the data stored in ROM is permanent and cannot be altered. It is typically used to store firmware or software instructions that are essential for the computer to function properly.

The statement is true because there are 1,000 kilobytes in a megabyte. Therefore, multiplying 1,000 by 10 gives us 10,000 kilobytes in 1 megabyte.

BIOS stands for Basic Input/Output System. It is a firmware that is responsible for initializing and controlling the hardware of a computer system. It provides the necessary instructions for the computer to start up and communicate with the various hardware components, such as the keyboard, mouse, and hard drive. The BIOS also performs a power-on self-test (POST) to check the system's hardware and ensure that it is functioning properly before handing over control to the operating system.

A bit is a fundamental unit of information in computing that represents a binary digit, which can have a value of either 1 or 0. It is the basic building block of digital data storage and processing, allowing computers to represent and manipulate information using binary code. This binary representation enables computers to perform calculations, store data, and execute instructions.

RAM stands for Random Access Memory and it is a type of computer memory that is used to store data that is currently being used by the computer's operating system, applications, and other processes. It is a volatile memory, meaning that its contents are lost when the computer is powered off or restarted. RAM allows for quick and temporary storage of data, allowing the computer to access and process information quickly. It is different from storage devices like hard drives or solid-state drives, which are used to store data for long-term use.

To connect a router to a cable modem, you would use an ethernet cable. An ethernet cable is a type of wired connection that allows for high-speed data transfer between devices. It is commonly used to connect devices such as routers, modems, computers, and gaming consoles. In this case, the ethernet cable would be used to establish a physical connection between the router and the cable modem, allowing the router to receive internet connectivity from the modem and distribute it to other devices on the network.

A network card, also known as a network interface card (NIC), is a piece of hardware that enables computers to communicate with each other over a network. It is inserted into a computer's motherboard and provides the necessary physical connection and protocols for data transfer. The network card allows the computer to send and receive data packets to and from other devices on the network, facilitating communication and enabling access to shared resources such as files, printers, and internet connectivity.

A cable modem is a piece of hardware that is used to connect a computer or a network to the internet through a cable television network. It is a device that converts the analog signal from the cable network into a digital signal that can be understood by the computer. Therefore, the statement "A cable modem is a piece of hardware" is true.

A normal Microsoft Word file is typically much smaller than 30 megabytes (MB). The size of a Word file can vary depending on the content, formatting, and embedded objects, but on average, a typical Word file is usually a few kilobytes to a few megabytes in size. Therefore, the statement that a normal Word file is about 30 megabytes is false.

One megabyte (MB) is equal to 1,000,000 bytes. This is because the prefix "mega" in the metric system denotes a multiplier of one million. Therefore, 1MB contains one million bytes.

A CD ROM can hold approximately 650 megabytes of data. This is the correct answer because CD ROMs typically have a storage capacity of 650 MB, which allows for the storage of a significant amount of data, such as audio files, videos, or documents.

A network card, also known as a network interface card (NIC), is a piece of hardware that allows a computer to communicate on a network. It is responsible for transmitting and receiving data over the network, enabling the computer to connect to other devices and access resources on the network. Without a network card, a computer would not be able to establish a network connection and participate in network communication.

A byte is a unit of digital information that consists of 8 binary digits or 8 bits. It is the fundamental building block of computer data storage and processing. Each byte can represent a single character or a small piece of data. The binary digits within a byte can have two possible values, 0 or 1, which can be used to represent different combinations of data. Therefore, the correct answer is that a byte is a series of 8 binary digits or 8 bits.

The number 1001 has 4 bits because it is a 4-digit binary number. Each digit in a binary number represents a bit, so the number 1001 has 4 bits.

A LAN, or Local Area Network, is a computer network that covers a small physical area, such as a home, office, or building. It allows computers and devices within the network to communicate and share resources, such as files and printers. LANs are typically used in a single location and are often connected to a larger network, such as the internet, through a router or modem.
