What is the relationship between a signal’s spectrum and its bandwidth. What is attenuation? Define channel capacity. What key factors affect channel capacity? Problems: Figure 1 shows the frequency domain function for a single square pulse. The signal pulse could represent a digital 1 in a communications system. Note that an infinite number of higher frequencies of decreasing magnitudes is needed to represent the single pulse. What implication does that have for a real digital transmission

What is Data Communications? Next Topic | TOC The distance over which data moves within a computer may vary from a few thousandths of an inch‚ as is the case within a single IC chip‚ to as much as several feet along the backplane of the main circuit board. Over such small distances‚ digital data may be transmitted as direct‚ two-level electrical signals over simple copper conductors. Except for the fastest computers‚ circuit designers are not very concerned about the shape of the conductor or

Review Question: 1. Explain the main differences between a file processing system and a database system ANS: Some main differences between a database management system and a file processing system are: * Both systems contain a collection of data and a set of programs which access that data. A DBMS coordinates both the physical and the logical access to the data‚ whereas a file-processing system coordinates only the physical access. * A DBMS reduces the amount of data duplication by ensuring

02. Compare and contrast between the bus and star topology. A network architecture in which a set of clients are connected by a shared communications line‚ called as a bus. A network consists of one central switch‚ hub or computer which acts as a conduit to transmit messages‚ called as a star. Bus networks are the simplest way to connect multiple clients‚ but often have problems when two clients want to transmit at the same time on the same bus. The star topology is a computer
