Accepted Answer

Once data has been summarized or manipulated, it becomes useful information for decision making. Code refers to instructions given to a computer, input is the raw data entered into a computer, and software is the programs and applications that run on a computer.

Question 4

Computers costing $500 to $5,000 that can fit next to a desk,on a desk,or be carried around are called ________.

Accepted Answer

Personal computers (microcomputers) are designed to be affordable and commonly used by individuals at home or in a small office setting. They are typically small enough to fit on a desk or be carried around, and can range in price from $500 to $5,000. Workstations, mainframes, and minicomputers are typically larger and more expensive, and are designed for use in larger organizations or for specialized tasks.

Question 5

Slower than a supercomputer,but still able to process millions of instructions per second,these computers are often access by means of a terminal and are sometimes called "midsize" computers.

Accepted Answer

The description matches that of a mainframe computer, which typically processes millions of instructions per second and is accessed through a terminal. Workstations and microcomputers can also be accessed through terminals, but typically do not have the processing power to match the description. Netbooks are smaller, less powerful devices that are not typically accessed through terminals.

Question 6

Embedded computers are known as ________.

Accepted Answer

Embedded computers are designed to perform a specific task within a larger system, and they typically consist of a microcontroller, which is a specialized type of microcomputer that includes built-in memory, input/output interfaces, and other features tailored to specific applications. Nanocomputers are a hypothetical technology that has yet to be realized, and supercomputers are high-performance computers used for complex scientific and technical computations.

Question 7

Users access mainframes by means of a ________,which has a display screen and a keyboard.

Accepted Answer

Users access mainframes through a terminal, which functions as an interface between the user and the mainframe system. The terminal has a display screen and a keyboard, and it communicates with the mainframe over a network or via a direct connection. A client is a software application that runs on a computer system and interacts with a server over a network. A server is a computer system that provides services to clients over a network. A local area network (LAN) is a network that connects computers and other devices within a limited area, such as a building or campus.

Question 8

Processing data from the U.S.Census requires what type of computer?

Accepted Answer

Processing data from the U.S. Census involves handling massive amounts of data, which requires a computer with a high processing power and storage capacity. Supercomputers are designed for this purpose, as they are capable of performing complex calculations and data analysis at a faster rate than other types of computers.

Question 9

These computers offer advanced graphics capabilities often used to create three-dimensional effects for movies:

Accepted Answer

Workstations are designed to handle complex graphics and processing tasks, often used in fields such as architecture, engineering, and film production. They offer advanced graphics capabilities including the ability to create three-dimensional effects for movies. Laptops are portable computers and may not have as powerful graphics capabilities as workstations. Mainframes and supercomputers are designed for large-scale data processing and are not typically used for graphics-intensive tasks.

Question 10

Tiny,specialized microprocessors installed in "smart" appliances and automobiles are called ________.

Accepted Answer

The specialized microprocessors used in smart appliances and automobiles are called microcontrollers. They are different from regular microcomputers as they have a specific set of functions and are designed to perform embedded tasks. Mobile Internet devices and personal digital assistants are not the same as microcontrollers.

Question 11

The computer circuitry that temporarily holds data waiting to be processed is known as ________.

Accepted Answer

Primary storage, also known as RAM (Random Access Memory), is the computer circuitry that temporarily holds data waiting to be processed. This type of storage is volatile, meaning that it loses its contents when the computer is turned off. Secondary storage, such as hard drives and flash drives, is non-volatile and is used for long-term storage of data. The CPU (Central Processing Unit) is the part of the computer that performs the actual processing of data, while the motherboard is the main circuit board that connects and controls all the other components of the computer.

Question 12

Devices such as PCs and workstations that are connected to a server are called ________.

Accepted Answer

Devices connected to a server are referred to as clients. The other options are not accurate descriptions of these devices.

Question 13

A central computer that holds collections of data and programs for connecting or supplying services to PCs,workstations,and other devices is called a ________.

Accepted Answer

A central computer that holds collections of data and programs for connecting or supplying services to PCs, workstations, and other devices is called a server. Clients are devices that connect to servers to access data and services, while a master/slave relationship refers to a hierarchical relationship where the master controls the slaves.

Question 14

When a user enters monthly bills into a family finance computer program,these amounts are considered to be ________.

Accepted Answer

The amounts that the user enters into the family finance computer program are considered to be input data, as they are the data that is being entered into the program for processing.

Question 15

Tower PCs are ________ whose case or main housing often sits on the floor,with the keyboard and mouse on top of the desk.

Accepted Answer

Tower PCs are a type of microcomputer, as they are smaller than mainframe or minicomputers and typically used for personal or office use. The other options, supercomputers and nanocomputers, are much larger or much smaller than a typical tower PC.

Question 16
