Question

1. Programmers at the Application layer use syntax and semantics to make use of a common computer language. One of these things are grammatical structure rules the other is how a computer is going to interpret the programing. Which is Syntax, and which is Semantics?

Syntax: Is the grammatical structure rules

Semantics: Interprets the programming

2. We use the same copper wire to send information from multiple sources what term is used to describe the ability to do this.

Data Transmission

3. Sets of rules used to coordinate messaging between devices across a network are called?

Protocol

4. A computer identifies what service is being used by the 16 bit-identifier signifying what virtual concept?

Convention Port Number

5. The time it takes for a signal to cross a network medium is called what?

6. Electrical radiation that can cause errors in data transfer is called what?

noise

7. True or False: We use electromagnetic waves that can be modulated to transmit data across a network. These waves are called a “carrier”.

False

8. Each host on a network has a unique 32-bit dotted decimal identifier called a what?

IP Address

9. The communication paradigm that uses a sequence of bytes to send information from application to another is called the ________ paradigm?

Stream

10. A high-capacity connection between the Internet Service Provider’s office and each local neighborhood is called a what?

LAN: Local Area Network

11. The error-detection scheme in which each transmitted message is accompanied by a numerical value based on the number of set bits in the message is which, the “Checksum” or the “CRC”?

Checksum

Need help with these ASAP! They need to be correct please. I have gotten some answers from here but they are not correct. Please help and answer all.

Thank you!

Explanation / Answer

1.syntax

explanation: programming languages have specific sytax if programmar doesn't follow syntax it may rises errors

2.Data transmission

explanation:data transmission or digital transmission is way of transforming data from point to point

example:coper wires, optical fibers

3.protocol

explanation:in telecommunications , a protocol is system of rules that allows two or more systems that communicate over a network

5.latency

explanation: time taken by signal to travel from source to destination through medium in one way is called latency, where as in 2ways it is called round trip time

6.jitter:

explanation:Jitter may be caused by electromagnetic interference and crosstalk with carriers of other signals

7.False

explanation:Radio waves are a type of electromagnetic radiation

8.IP address

explanation:every host must have 32bit unique id called ip address

9.stream

explanation: communication provides two types of transmissions: steam and message

stream paradigm uses sequence of transmission of individual bytes

where as message tramsission uses sequence of individual messages

10.LAN

explanation: lan is a computer network that spans a relatively small area within bulding or office and uses at high speed

11.checksum

explanation:Check Sum is a simple error-detection scheme in which each transmitted message is accompanied by a numerical value based on the number of set bits in the message.
