ITN 101 MIDTERM EXAM REVIEW
1. network
Answer A group of computers and other devices (such as printers) that are connected by and can exchange data via some
type of transmission media, such as a cable, a wire, or the atmosphere.
2. topology
Answer how parts of a whole work together
3. Physical Topology
Answer The physical layout of the media, nodes, and devices on a network. It does not specify device types, connectivity
methods, or addressing schemes.
4. logical topology
Answer A characteristic of network transmission that reflects the way in which data is transmitted between nodes,
including how access to the network is controlled and how specific resources are shared on the network. May ditter from its physical
topology.
5. P2P (peer-to-peer) network model
Answer A network in which every computer can communicate directly with every other computer. By default, no
,computer on a P2P network has more authority than another.
6. scalable
Answer The property of a network that allows an administrator to add nodes or increase its size easily.
7. server
Answer Any computer or application that provides a service, such as data or other resources, to other devices.
8. client-server network model
Answer A network where resources are managed by the NOS via a centralized directory database.
9. domain
Answer In the context of Windows Server NOSes, a group of users, servers, and other resources that share account and
security policies.
10. AD (Active Directory)
Answer The centralized directory database that contains user account information and security for the entire group of
computers on a network.
11. AD DS (Active Directory Domain Services)
Answer The Active Directory service that manages the process allowing a user to sign on to a network from any
computer on the network and get access to the resources that Active Directory manages.
,12. client
Answer A computer or application that makes a request from another computer or application.
13. network services
Answer A resource the network makes available to its users, including applications and the data provided by these
applications.
14. client-server applications
Answer Data or a service requested by one computer from another.
15. protocols
Answer A standard method or format for communication between network devices.
16. TCP/IP
Answer A suite of networking protocols that includes TCP, IP, UDP, and many others. TCP/IP provides the foundation
for data exchange across the Internet.
17. web service
Answer A web server serves up web pages to clients. Many corporations have their own web servers, which are available
privately on the corporate network. Other web servers are public, accessible from anywhere on the Internet. The primary protocol
used by web servers and browsers (clients) is HTTP (Hypertext Transfer Protocol). When
, HTTP is layered on top of an encryption protocol, such as SSL (Secure Sockets Layer) or TLS (Transport Layer Security), the result
is HTTPS (HTTP Secure), which gives a secure transmission.
18. email services
Answer Email is a client-server application that involves two servers. The client uses SMTP (Simple Mail Transfer
Protocol) to send an email message to the first server, which is sometimes called the SMTP server (see Figure 1-4). The first
server sends the message on to the receiver's mail server, where it's stored until the recipient requests delivery. The recipient's
mail server delivers the message to the receiving client using one of two protocols
Answer POP3 (Post Oflce Protocol, version 3) or IMAP4 (Internet Message Access Protocol, version 4). Using POP3, email is
downloaded to the client computer. Using IMAP4, the client application manages the email while it's stored on the server.
19. FTP Service
Answer FTP is a client-server application that transfers files between two computers, and it primarily uses FTP (File Transfer
Protocol). FTP does not provide encryption and is, therefore, not secure.
20. Telnet service
Answer The Telnet protocol is used by the Telnet client-server command-line application to allow an administrator or other
user to "remote in" or control a computer remotely. Telnet is included in many operating systems, but transmissions in Telnet are not
encrypted, which has caused Telnet to be largely replaced by other, more secure programs, such as the ssh command in the Linux
