An analog signal is digitized and stored in a file. For digitizing with 8 bits, if data rate is 134,4 Kbps and the total time of the signal is 10 min, which answer is correct? O a. Frequency = 8,40 KHz File Size = 1,48 Mbit O b. Frequency = 16,80 KHz File Size = 2,96 Mbit O c. Frequency = 4,20 KHz File Size = 1,29 Mbit O d. Frequency = 10,00 KHz File Size = 1,61 Mbit O e. Frequency = 9,80 KHz File Size = 739,2 kbit Which term is related to LAN communication? O a. Point to point communication O b. Direct link O c. All O d. Shared link O e. Dedicated link Which one is not defined correctly? O a. Internet is basically having nodes and end points O b. Intranet is used connecting the network of companies with other companies O c. Internet is the combination of networks O d. Connection between a distributor and seller can be considered as extranet O e. None In an asenkron transmission a character size is 6 bits. When 2600 characters are transmitted, if total amount of data transmitted is 26 kbit, which answer is correct? O a. Stop Bit = 1 Parity = "Even" Total Overhead = 8,10 Kbit O b. Stop Bit = 1,5 Parity = "No" Total Overhead = 6,25 Kbit O c. Stop Bit = 1 Parity = "Even" Total Overhead = 9,00 Kbit O d. Stop Bit = 2 Parity = "Even" Total Overhead = 9,20 Kbit O e. Stop Bit = 2 Parity = "Odd" Total Overhead = 10,40 Kbit
