Fundamentally, digital communication involves the transfer of information between two people on the internet, or through a digital format. The message appears in the form of bits that has to decoded by a program before being able to get the message as intended by the sender. When sending a message, the sender puts it in bits. Each particular message has a specific number of bits, including start and stop bits (Martini and El-Aawar 344). When the receiver of the message reads it, he or she has to interpret all the bits so that the message could come out as ...

I/O modules are normally the third most vital constituent of computer systems after the memory and the CPU. The requirements for computer systems are to have an efficient means for receiving inputs and delivering outputs. Computer systems have a variety of peripherals that deliver data at different speeds, in a wider variety of sizes and at different formats. External devices are generally not connected to the expansion or the systems bus structure of computer systems (Tarnoff 350). The problem arises in that I/O modules are slower than the RAM and the CPU, but a handful are actually faster. The ...

Abstract

A look at the problems that face the world which include wars, disease, and injustice among others would prompt a re-evaluation of the social system that is in place. It is evident that the system has not led to an overall improvement in humanity. The common underlying factor among the various social ills that face the world today is the adoption of capitalism as the predominant mode of production and social ordering. The need to outdo the competition and maximize productivity in order to increase profits as the primary motivation for capitalism makes the system susceptible to abuse hence ...

A History

How the past is perceived and how the many stories we pass on from generation to generation are preserved has a great deal to do with what religion holds sway in that time and of course, how popular culture chooses to depict historical events. Many upon many visions of the past have likely been skewed to serve a greater purpose or expunge qualities and practices of a culture that do not paint a pleasant picture of those who are descended from those who participated in such events. Religion tends to give voice to the past in a manner that ...

a) Can a printer, printing 40 characters per second, keep up with a string of ASCII characters (one byte per symbol) arriving serially at the rate of 300 bps?

1 Bytes = 1 symbol

The number of bits per character is usually 10 thus using 10 bits per word.

Therefore 300 bytes per second = 30 characters per second

So if a printer is printing 40 characters per second and the string of ASCII characters is 30 characters per second according to the above explanation, then the printer can keep up with that number.

What about 1200 bps?

1200 bytes per second implies 120 characters ...
