(56 cards)
What are the topics for this Module?
- Client and Servers
- Network Components
- ISP Connectivity Options
It is located within the smartphone enable the phone to connect to local networks and the internet.
Wi-Fi transmitters and receivers
are host that has software installed which enable them to provide information to other host on the network
Server
Are computer host that has software installed that enable the host to request and display the information obtained from the server.
Client
What is an example of client software?
Web browser like chrome or edge. Also Outlook for emails.
All computers connected to a network that participate directly in network communication are classified as _________.
hosts
In small businesses and homes, many computers function as the _________ on the network.
servers and networks
This type of network is called a peer-to-peer (P2P) network.
A computer that function as a server and host
Give an example of simplest P2P network
Two directly connected computers using either a wired or wireless connection. Both computers are then able to use this simple network to exchange data and services with each other, acting as either a client or a server as necessary.
What is the main disadvantage of a P2P environment?
The performance of a host can be slowed down if it is acting as both a client and a server at the same time.
In larger businesses, why it is often necessary to have dedicated servers to support the number of service requests?
Because of the potential for high amounts of network traffic.
What are the advantages of peer-to-peer networking?
- Easy to set up
- Less complex
- Lower cost because network devices and dedicated servers may not be required
- Can be used for simple tasks such as transferring files and sharing printers
What are the disadvantages of peer-to-peer networking?
- No centralized administration
- Not as secure
- Not scalable
- All devices may act as both clients and servers which can slow their performance
__________ allows a device to act as both a client and a server within the same communication
P2P Application
_________ require that each end device provide a user interface and run a background service.
P2P Applications
What is a hybrid system in P2P Application?
Where resource sharing is decentralized, but the indexes that point to resource locations are stored in a centralized directory. In a hybrid system, each peer accesses an index server to get the location of a resource stored on another peer.
computer can run multiple types of server software. In a home or small business, it may be necessary for one computer to act as a ____________________________
file server, a web server, and an email server.
A single computer can also run multiple types of client software. There must be client software for ____________ required.
every service
With multiple clients installed, a host can connect to multiple ________ at the same time.
server
For example, a user can check email and view a web page while instant messaging and listening to internet radio.
What are the network infrastructure contains three categories of hardware components?
- End devices
- Intermediate devices
- Network Media
It is often the visible components of the network platform.
Hardware. Devices and media
Some network components are not visible such as?
wireless media, messages are transmitted through the air using invisible radio frequencies or infrared waves.
The network devices that people are most familiar with are called ?
end devices. Which can be classified as hosts
List some end devices
- Computers (workstations, laptops, file servers, web servers)
- Network printers
- Telephones and teleconferencing equipment
- Security cameras
- Mobile devices (such as smart phones, tablets, PDAs, and wireless debit/credit card readers and barcode scanners)
