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 ...

Summary

Cyber laws are established to ensure safe, fair and responsible use of the internet by all the users whether they are common internet using citizens or law enforcement agencies. These laws have been designed and have been evolving ever since because of the ever expanding canvas of the ethical considerations involved in the use of the internet. The law is confined to logic and debate, and anything that has not been debated on or legislated cannot be made a law and is hence the responsibility of the user as their ethical and moral duty. The common internet ...

Introduction

The advancement in computing technologies has been accompanied by increased exposure of the users to ethical violations including software threats, immorality, legal issues, confidentiality, and trust. The use of computers affects people’s decisions as well as how they make them. Computers persuade, facilitate, and enable various human cognitive processes, attitudes or processes while inhibiting and discouraging others. For example, while performing an internet search, internet search engines usually prioritize and provide information in a given order. As such, they influence what internet users see. These technological artifacts become “active mediators” because they shape people’s actions and perceptions, ...

Introduction to IT security

A set of hardware, firmware or software components that are critical to computer security can be termed as trusted computing base. These set of hardware and firmware are suitable in the sense that vulnerabilities occurring inside the system can jeopardize the functioning of the system. The security policy determines the security standard of the systems. All parts of the computers outside the trusted computing base must to at any cost be able to function in a way that would probably leak any more privileges than as specified in the policy specification In each security mechanism, there is a need for ...
