Packet switching vs Circuit switching

What is the key characteristic of circuit switching?

• Data packets are sent separately and take different paths

• The connection is established dynamically depending on network load

• A dedicated path is established before communication begins

• The connection remains open until the communication ends

What is one of the advantages of circuit switching?

• High efficiency in bandwidth utilization

• Provides real-time communication without packet reordering

• Dynamic routing allows for faster transmission

• More scalable for handling large volumes of traffic

What is the main disadvantage of circuit switching?

• All bandwidth is used even when no data is being transmitted

• Packets can take different routes, causing delays

• Data packets require complex protocols for delivery

• High potential for packet loss due to congestion

How does packet switching handle data transmission?

• A dedicated path is established for all data

• Data is broken into packets, each of which follows independent routes

• Packets are always received in order without delays

• All data follows the same path, as in a telephone network

Which protocol is usually associated with packet switching?

• UDP

• HTTP

• FTP

• TCP

In what situation is packet switching preferable compared to circuit switching?

• When real voice communication is required

• When a fixed, continuous connection is necessary

• When it is necessary to efficiently process large volumes of data

• When bandwidth must be reserved for a single user

Which of the following steps is NOT a step in channel switching?

• Establishing a channel

• Data transmission

• Packet fragmentation

• Disconnecting the connection

What problem can occur in packet switching but not in circuit switching?

• Bandwidth reservation

• Packet loss due to congestion

• High cost of maintaining a connection

• Low latency in real-time applications

How does packet switching improve network efficiency?

• It reserves bandwidth for each user

• Packets dynamically share network resources

• Each packet is assigned a fixed route

• It establishes a dedicated connection for the entire transmission

Why is packet switching unsuitable for real-time applications such as voice calls?

• It guarantees bandwidth reservation for each session

• It can cause delays and out-of-order delivery of packets

• It always follows a pre-established route

• It does not require routing or switching devices
