Computer Hardware Guide to Reading
Main Ideas Key Terms
Computer systems are composed of users, hardware, software, and data. The four basic categories of computer hardware are processing components and input, output, and storage.

Computers and the Computer System
A computer system consists of four parts:
hardware
The physical components of the computer. (p. 34) • A user •
Hardware
•
Software
• Data
software
The set of instructions that tells the computer what to do. (p. 34)

Computer Software Guide to Reading
Main Ideas
Operating system software allows users to give instructions to the computer and to execute applications. Applications are software packages that help users perform specific tasks.
Key Terms
basic input/output system (BIOS) operating system (OS) graphical user interface (GUI) application software multitasking

Computer Software
Operating System Software
The
basic input/output system (BIOS)
activates the
operating system
. The OS is divided into four major categories: • Task management • Memory management • Input and output management •
Graphic user interface basic input/output system (BIOS)
Small program that performs basic startup activities, such as activating the computer’s operating system. (p. 40)
operating system (OS)
Software that specifies how the computer receives and processes input; acts as an interface between a user and the computer hardware. (p. 40)
graphical user interface (GUI)
Type of interface that allows users to interact with software by selecting words, symbols, or graphics from a desktop. (p. 41)

Computer Software
Application Software
Most of the time when you use a computer, you are using
application software
.
Today’s operating systems are capable of
multitasking
. This allows you to work with more than one application or document at a time.
application software
Computer programs that allow users to perform a specific task on the computer; also referred to as applications. (p. 41)
multitasking
Working with more than one application or document at a time. (p. 41)

Networks Guide to Reading
Main Ideas
Networks allow computers to share information, messages, and software. Dial-up, broadband, and wireless are three types of network connections.
Key Terms
network local area network (LAN) wide area network (WAN) server client network interface card (NIC) modem

Networks
Types of Networks
A
network
can connect two computers in a home or millions of computers around the world, as in the case of the Internet. Networks can be divided into two basic categories: •
local area networks
•
wide area networks network
A system in which communication lines or wireless connections are used to connect computers together. (p. 43)
local area network (LAN)
Type of network that connects computers in a single location, such as a single department within a company. (p. 43)
wide area network (WAN)
Network that connects computers across a wide geographical area, such as a region of the United States. (p. 43)

Network Interface Cards
•
Modems
• Routers
server
A powerful central computer that manages files and services for a network. (p. 45)
client
In a network, the individual computers that are part of that network. (p. 45)
network interface card (NIC)
Provides the place to plug the network cable into the computer, and it creates and sends the signal from one network component to another. (p. 45)
modem
Hardware device that enables a computer to send and receive signals through telephone wires or cable. (p. 45)

Network Software
Networks are controlled by a specific group of software called a network operating system, or NOS. The NOS is responsible for managing network resources, controlling who can access different network components, and keeping the network running smoothly.

Creating a One Page Web Site
Creating and Saving a Web Page
When saving your Web sites, you need a plan. Develop a system of
folders
and
subfolders
to locate your Web pages easily. FrontPage offers
templates
that simplify creating Web sites. Some templates contain
placeholder
text that you simply replace with your own content.
folder
An item that helps the user organize files. (p. 48)
subfolder
A folder contained within a folder; used to further organize files. (p. 48)
template
A reusable pattern that helps you place information quickly and efficiently on a Web page. (p. 49)
placeholder text
