▪ is a common communication network
scheme used for telephone calls

Study These Flashcards
A

Circuit Switching

22
- It offers a dedicated transmission channel that is reserved until is disconnected.
PROS IN CIRCUIT SWITCHING
23
▪ Most data that moves over the internet in an entirely different way. ▪ A mode of transmission in which the message is broken into smaller parts which sent independently, and then resemble at the ultimate destination. ▪ More efficient
Packet Switching (packets)
24
- It offers the capability of storing messages temporarily to reduce network congestion.
KEY FEATURES IN CIRCUIT SWITCHING
25
- Dedicated channels can cause delays because a channel is unavailable until one side disconnects. - It uses a dedicated physical link between the sending and receiving devices.
CONS IN CIRCUIT SWITCHING
26
▪ Packets can be routed around network congestion. ▪ Packet switching makes efficient use of network bandwidth.
PROS IN PACKET SWITCHING
27
▪ Packets can get lost while taking alternative routes to the destination. ▪ Messages are divided into packets that contain source and destination information.
CONS IN PACKET SWITCHING
28
▪ The two types of packet switching are datagram and virtual circuit. ▪ Datagram packets ▪ Virtual circuit
KEY FEATURES OF PACKET SWITCHING
29
two types of packet switching
- Datagram packets - Virtual circuit
30
– independently sent and can take different paths throughout the network.
Datagram packets
31
Computers Do on the Internet
- SERVERS - CLIENTS - AD DS (Active Directory Domain Services) - DNS (Domain Name System) - FILE SERVER - WEB SERVER II - PRINT SERVER - ROUTER
31
uses a logical connection between the source and the destination device.
Virtual circuit
32
▪ computers work like electronic filing cabinets that store information and send it when clients request. ▪ a computer that is designed to process any requests for data and delivers data to other client computers over a local network
SERVERS
33
computer that gets information from a server
CLIENTS
34
A computer that holds the user accounts, computer accounts, organizational units, application services
AD DS (Active Directory Domain Services)
35
▪ machine that helps Dynamic Host Configuration Protocol (DHCP) server ▪ a server that configures IPv4 and IPv6 addresses
DNS (Domain Name System)
36
▪ machine that holds and manages documents
FILE SERVER
36
▪ machine that holds users’ mail services and Web services
WEB SERVER II
37
▪ the internet is made up of a hardware device designed to receive, analyze, and send incoming packets to another network ▪ it can be compared to a simple mailbox placed at the corner of a street and which represents a single point of entry to the worldwide network
ROUTER
37
▪ a device that connects printers to client computers through the internet ▪ it accepts print jobs from the computers, queues these jobs, and sends them to the appropriate printers
PRINT SERVER
37
❑ the collection of public websites that are connected to the internet worldwide, together with client computers ❑ considered to be one of the applications in the internet and computer networks ❑ THREE (3) FUNDAMENTAL TECHNOLOGIES
World Wide Web (WWW)
38
THREE (3) FUNDAMENTAL TECHNOLOGIES IN WORLD WIDE WEB
▪ HTML ▪ HTTP ▪ WEB SERVERS and WEB BROWSERS
38
HTML MEANS
Hypertext Markup Language
39
❑ classified as the set of standards allowing users of the WWW to interchange information seen on the web pages ❑ PORT 80 – standard port for HTTP connections ❑ directs to hypertext document accessible through the internet
Hypertext Transfer Protocol (HTTP)
39
❑ a standard markup language used for creating web pages ❑ classified as the set of markup symbols or codes appended in a file intended for presentation on a WWW browser page
Hypertext Markup Language (HTML)
39
HTTP MEANS
Hypertext Transfer Protocol
39
standard port for HTTP connections
PORT 80
40
a software application for recovering, presenting, and navigating information resources on the WWW
Web Servers and Web Browsers
41
▪ website maintenance ▪ modify the website content as well as add new information
WEB ADMINISTRATOR
42
TWO (2) mainly managed search tools
- subject directories - search engines
43
developed and maintained by human editors and not by electronic spiders or robots that are used to fetch web pages automatically
subject directories
44
Types of search engines
- spiders or bots - GOOGLE
45
uses small programs that polish the internet, follow links, and return information to the search engine’s indicator o example: Googlebot, Yahoo Slurp, MSNbot
spiders or bots
46
most popular search engines
GOOGLE
