What is a computer network?
A way to connect devices to share data
Web pages that can be shared globally
A dedicated line from one computer to another
A set of IP addresses needed to access other computers
What are the connected steps between a sending and a receiving location called?
A route
A heuristic
A path
A conduit
What is bandwidth
How long it takes 10 megabytes of data to be sent
The amount of data that can be sent in a fixed period of time
The delay in how long it takes between requesting and loading a web page
The amount of data divided by the latency
Why is Internet routing usually dynamic?
So that if a path on the route is congested or not working, a new path can be assigned
So that it can speed up or slow down as necessary to avoid data congestion
So that new routes can be tested before being available globally
So that as noise on a route becomes louder, traffic can e limited until it reaches acceptable levels
What is the name for the protocol that handles processing at the sending and receiving locations?
Local Area Network Protocol
Point-to-point Protocol
Transmission Control Protocol
Redundancy Protocol
What is the number assigned to devices on the Internet?
Internet Protocol address
Domain number
Host number
Router location
How do packets know how to get to their destination?
The router knows the path and sends it step-by-step to its final destination
Each path has an embedded code that directs the packets to the correct location
The destination location emits pulses that guide the data packets to its location.
The destination IP address is included in each packet.
Why is the Internet considered to be fault-tolerant?
It has dedicated lines between devices
It has duplicate paths to all locations
It is secured against all threats
It is open to anyone with a connection
What is the World Wide Web?
A collection of wires and cables to connect devices
Another name for the Internet
A way to search for and share documents and resources
A browser
What can be determined by comparing the time it takes different systems to complete the same task?
Efficiency
Reliability
Speedup
Validity
A parallel computing system uses multiple computers to run
sections of the data at the same time
the same data to measure the fastest ISP
sections of the program at staggered times to avoid overlap
sections of the program at the same time
Which computing system can process larger datasets when multiple devices are combined because of the additional memory and storage provided?
Distributed
Incremental
Dispersed
Sequential
Which of the following is true about packets?
Packets leave and arrive at their destination at the same time
Packets travel along different paths to their destination
Each router decrypts the packets to confirm their destination
If a packet does not arrive at the destination, the entire message is resent.
Which of the following is false about HTTPS?
HTTPS uses Certificate Authorities (CAs) to verify a site's identity
HTTPS encrypts data before it is separated into packets
HTTPS ensures the secure sharing of data
HTTPS trades faster performance for more security
Why is there a lmit to adding additional devices to a parallel system?
The processor speed is limited and additional devices cannot create additional speedup
There are only so many configurations to connect devices in parallel
Space and connections to power in a building limit the number of devices
The amount of time the sequential part takes to run cannot be shortened by adding devices.
