Question 1

Clock speed on a computer is measured most recently in:

Accepted Answer

Clock speed on a computer, which indicates how many cycles a CPU can perform per second, is most commonly measured in Gigahertz (GHz) in modern computers. This reflects billions of cycles per second.

Question 2

Higher clock speeds usually mean ________ performance.

Accepted Answer

Higher clock speeds generally mean faster performance because the CPU can execute more cycles per second, leading to quicker processing of instructions.

Question 3

_____ temporarily locates data and instructions before processing.

Accepted Answer

Memory is used to temporarily store data and instructions before they are processed by the CPU.

Question 4

Computers have long-term memory called:

Accepted Answer

ROM (Read-Only Memory) is considered a type of long-term memory in computers because it retains its contents even when the power is turned off, unlike RAM (Random Access Memory), which is a type of short-term memory.

Question 5

____ contains instructions and data that only special devices can alter.

Accepted Answer

ROM (Read-Only Memory) contains instructions and data that are permanently written during the manufacturing process, and only special devices can alter this information, unlike RAM (Random Access Memory) which can be read and written to by the CPU during normal operation. KB (Kilobyte) and GB (Gigabyte) are units of digital information storage and do not pertain to the characteristics of being alterable or not.

Question 6

____ stores data only until they are no longer needed, or until you shut down the computer.

Accepted Answer

RAM (Random Access Memory) is a type of computer memory that stores data temporarily and is volatile, meaning it loses its contents when the power is turned off.

Question 7

Keyboards, pointing devices (such as a Wii, mouse, or touchpad), scanners, and digital cameras are examples of:

Accepted Answer

Input devices are hardware components used to enter data or instructions into a computer system. Keyboards and pointing devices like a mouse or touchpad allow users to input data directly. Scanners and digital cameras capture images or documents and convert them into digital data that the computer can process.

Question 8

Examples of _____ include the computer hard drive, CDs, DVDs, USB flash memory, and external hard drives

Accepted Answer

These are all examples of storage devices, which are used to store data for long-term access.

Question 9

_______, both wired and wireless, allow you to connect to a remote network over a telecommunications line, such as the telephone or cable TV service.

Accepted Answer

Modems are devices that modulate and demodulate signals for transmission over telephone lines or cable systems, allowing computers to connect to the internet or other remote networks either through wired or wireless connections.

Question 10

The digital signals going out from your computer into an analog signal appropriate for the connection medium used is called:

Accepted Answer

Modulation is the process of converting digital signals from a computer into analog signals suitable for transmission over a particular medium. This is necessary for sending data over traditional phone lines or other analog transmission systems.

Question 11

Converting an analog signal back into a digital signal that your computer can recognize is called:

Accepted Answer

Demodulation is the process of converting an analog signal back into a digital signal that a computer can recognize. Modulation is the opposite process, where a digital signal is converted into an analog signal for transmission.

Question 12

You can think about _____ as information that specifies how a hardware device should work with other data, information, and knowledge:

Accepted Answer

The answer of You can think about _____ as information...

Question 13

The _____ software coordinates and handles the details of working with the computer hardware.

Accepted Answer

The operating system (OS) is the software that coordinates and manages the hardware of a computer, acting as an intermediary between applications and the physical components of the device.

Question 14

_____ software provides additional tools that you can use to maintain and service your system

Accepted Answer

Utility software is designed to help analyze, configure, optimize, or maintain a computer. It provides tools for system maintenance and services beyond the basic functionalities of the operating system.

Question 15

A(n) ____ application is an example of utility software that helps guard your computer against unauthorized access when connected to a network.

Accepted Answer

A firewall is specifically designed to monitor and control incoming and outgoing network traffic based on predetermined security rules, thereby helping to protect your computer from unauthorized access.

Question 16

_____ software is a complete, self-contained program or set of programs for performing a specific job.

Accepted Answer

Application software is designed to perform a group of coordinated functions, tasks, or activities for the benefit of the user. It is a complete, self-contained program or set of programs that help users perform a specific job or task.

Question 17

Microsoft Word is an example of:

Accepted Answer

Microsoft Word is primarily used for creating, editing, and formatting text documents, making it an example of document preparation software.

Question 18

Microsoft Access is an example of:

Accepted Answer

Microsoft Access is a database management system (DBMS) that allows users to store, retrieve, manage, and manipulate data.

Question 19

Microsoft Outlook is an example of:

Accepted Answer

Microsoft Outlook is primarily an email client that also includes calendar, task manager, contact manager, note taking, journal, and web browsing functionalities. It does not fit into the categories of document preparation, electronic spreadsheet, presentation graphics, or database management system software.

Question 20

An example of a Personal Information Management system is:

Accepted Answer

None of the options listed (Microsoft Word, Excel, PowerPoint, Access) are primarily designed as Personal Information Management systems, which are typically used for managing personal data like contacts, calendars, and emails.
