Reading Exercises:
Exercise 1. Read and memorize using a dictionary:
multiplexing, time slot, consecutive, temporary, auxiliary, dial-up connection, data stream, rate |
Exercise 2. Answer the questions:
Why does the receiving end have to separate the individual signals?
What are two main types of multiplexing methods?
Why are the processing and storage capacities of computer hardware usually given in kilobytes, megabytes, gigabytes, and terabytes?
What do auxiliary storage units include?
How can be data transferred?
Exercise 3. Are these sentences true or false?
Most digital computer systems have four types of memory.
A byte consists of a string of ten consecutive bits and makes up the basic information processing unit of a computer.
Frequency-division multiplexing is typically used for analog signals.
One kilobyte eqauls 1,024 bytes.
One gigabyte eqauls 1 trillion bytes.
Exercise 4. Match the left part with the right:
1. ISDN connections are used |
a) very small. |
2. The range of DSL signals, however, is
|
b) dense wavelength-division multiplexing. |
3. Optical-fibre networks can use
|
c) to provide a variety of digital services to customers, including digital voice telephone, fax, e-mail, digital video, and access to the Internet. |
4. ISDN is faster than |
d) an ordinary dial-up connection (at about 56 kbps) |
