Contract Analysis
Introduction
People have a usual misconception that contracts are the same as agreements; the only difference is that when an agreement encompasses enforceability by law when is it becomes a contract. The provisions of the law in which the five essential elements should exist in order to consider its validity bind contracts. An enforceable contract must demonstrate offer and acceptance, legal objective, mutual obligations, consideration and competent parties. These elements will be explored by analyzing an actual contract and determine whether it constitutes all the aforementioned elements. For this analysis, the sampled contract will be an actual ...

Discussion 1

I agree that Bash is a good preference for the Linux shell because it has all of the features that an average Linux user would need. Granted that Bash does not have the advanced features that other shells have and that other users may need, I think that for students like us who are beginners with Linux, then the Bash would be a good shell to learn. Moreover, since it is the default shell used on Linux systems, then it will most likely be available from any Linux system that students access. This would save them a lot of ...

First Response

The NFS offers the Linux and UNIX users the ability to share and even transfer information and data from a single PC to another. The NFS system is highly available in the Windows operating system, more than it is in the UNIX system. The NFS, however, can be loaded by the use of the Server Message Block (SMB), which make up the CIFS. The NFS processor makes information readily available. The operation of the NFS system depends on the relationship between the UNIX and the Linux operating systems. For the information to be transmitted from one place to another, ...

Linux distributions have for a long time been associated with enhanced computer security; this is related to the nature of the file format that the Linux kernel implements. Currently, however, security has become a major security concern when dealing with different Linux distribution. Security threats range from malware attacks to denial of services attack. Most Linux distribution provides security features that are used to protect the computer from different attacks. The most fundamental are SELinux.

SELinux

SELinus is a Red Hat distribution is package used to enhance security. This application implements mandatory access control architecture that provides access controls for ...

1. An environment variable enables a program interact with the operating system by helping the program know where to store temporary files, where to install files, where to look for settings etc. Environment variables ultimately create and manage the environment in which a program runs. Environment variables help programs know what directory to install files in, where to store temporary files, where to find user profile settings, and other things. It can be said that environment variables help to create and shape the environment of where a program runs.
Environment variables are typically name-value string pairs that are dynamic ...

Question1.

A Linux distribution for a long time has proven to be best among many when it comes to issues security. The ability mainly due to the different built-in features of safety provided. Secure socket shell communication is one of the many security features provided in Linux. SSH is a UNIX-based command driven interface protocol that is used to get access to remote computers.
Access to the secure socket shell is controlled through the use of digital signatures and password. Both on the client side and server side encryption of the data being transmitted ensure secure communication (Satoh, Nakamura & Ikenaga, ...

Response 1:

The response recognizes /etc/inittab as a critical file and command in the management of Runlevel services. It is true that it has a number of lines, which guide an individual on the default Runlevel that the computer should embrace during normal booting. The response is also careful to explain that there are other significant lines that guide the system on the best commands to run during certain Runlevels (Love, 2007).
Runlevel services are usually managed by a number of commands. Such commands are the init as well as telinit commands for the 3.3.3 Runlevel. The init 1 and telinit ...

Purpose of an acceptable use policy

An acceptable use policy is a policy that a user should agree to follow so that they are allowed to use a computer resource. Many organizations require that employees and other computer resource users sign acceptable use policy before they start use the computer resources. They provide the etiquette in which computer resources will be used in the network. AUP is supposed to define what needs to be followed in the use of computers. They will define the limits that each group has, and the privacy that is to be followed. AUP is meant to protect group members from getting illegal content ...

According to Schoenfield, Stewart & Ransome (2015), information system threats are a major problem facing IT systems globally because of the growth in the use and development of computer networks aimed towards supporting information systems. Information systems are finding use in industries that require to keep their data confidential and away from unauthorized access such as banks, production companies, manufacturers, databases with private information, hospitals, government systems just to mention a few. It is therefore critical to identify threats that may face a system and adopt mitigation strategies aimed towards reducing the impact of such threats when they occur or ...

1. The causes of conflicts in Linux software packages are discussed as follows:
32-bit vs 64-bit conflict: Conflict between 32-bit and 64-bit versions of the same package often arises. Some processors are able to run programs that use different register and pointer sizes as seen in 64-bit X86 processors running in legacy mode 32-bit executables (Artho et al., 2012). For this to happen, all the shared libraries needed by the processor must also be available as 32-bit libraries. The way to go about this is the support by distributions to allow side by side installation of both 32-bit and ...

The Basic Infrastructure Routing

The basic infrastructure n routing refers to the channel in which internet connection is linked and flow. The center of any basic routing is a server computer. The moment the router is connected in an appropriate manner, creation of a basic infrastructure is a very simple thing. Creation of Infrastructure Mode Access Points in a company’s communication system is similar to creating it on a single computer. When using; OS X, Linux, Mac, and Windows is an easy task. In most cases, for most Windows, the operating systems they use creates an ad-hoc network by the means that are default. For instance, ...
