Information Technology Essays (Examples)

In the early days of information technology, some of the industry’s leading professionals were self-taught people who mastered computers as they became increasingly common in the modern workforce. Today’s information technology professionals may have the same independent spirit, but also need to be well-versed in the common computer technology and programs that are used in a variety of organizational settings. Whether you want to work in education, business, government, healthcare, or another type of organization, the best way to start a successful career in modern information technology is through a formal information technology or computer science degree program.

Information technology professionals have to start with the basics of computer programming. Though many people in the field will never actually have to write any programs, but will, instead, work with existing software, understanding programming is a critical part of any information technology job position. Therefore, students must be familiar with C++. This computer language is considered a hybrid language and is general-purpose object-oriented programming language with the convenience of having pre-defined classes. It is used in a wide variety of programming scenarios.

While you may not ever tackle programming in your professional life, there are three areas of information technology study that every computing professional will have to understand: hardware, software, and security. Computer hardware refers to the physical components of a computer or computing system. You are probably already familiar with the hardware that most users have on or in their own computers: motherboards, central processing units (CPU), random access memory (RAM), hard drives, solid state drives, optical drives, video cards, power supplies, monitors, keyboards, mice, heat sinks, data cables, fans, battery backups, webcams, flash drives, printers, speakers, tablets, sound cards, and modems. However, as an IT professional, you will be expected to understand network hardware like: routers, network switches, repeaters, bridges, access points, printer servers, firewalls, and cables or wireless communication devices that allow network computers to communicate with one another.

Software refers to computer data or instructions and is subdivided into two groups: system software and application software. System software runs the computer or network, while application software is task-specific. IT professionals are expected to be proficient with today’s most commonly used software, which includes Microsoft applications for general office usage, but may also include very industry-specific programs in some areas.

Computer security refers to protecting a computer or computer system. Many people think of computer security strictly in terms of protecting the software or the data stored on a computer or network from virtual attacks. While this type of security is important, it is equally important to consider the physical security of hardware; if hardware is accessible, then the data on the computer is vulnerable.

If you explore systems analysis and design, the you will need to combine all three of those components to create a system that balances the need for user-friendliness with the need for security. System designers must be able to anticipate the needs for a system, design the system components, chose the software to run on the system, and possibly design databases that can manage data and help coordinate between users.

Access Control Methods for Information Systems

Words: 1339 Length: 4 Pages Document Type: Essay Paper #: 43513414

Introduction
In the field of information security, access control refers to the selective restriction of access to a resource. It is a security technique that is used to regulate who or what can use or view a resource within a computing environment. Basically, there are two main types of access controls namely logical and physical. Physical access control will limit the physical access to buildings, and IT assets, while logical access will limit connection to computer networks, data, and system files (Younis, Kifayat, & Merabti, 2014). Access control systems are charged with performing identification, authorization, authentication, approval, access, and accountability of the entities by using login credentials. There are three main types of access control that will be discussed in this paper namely mandatory access control, discretionary access control, and role-based access control.
Elements of Access Control
Mandatory access control (MAC) is a security strategy where only the administrator has…… [Read More]

Warehouse Management System

Words: 1069 Length: 3 Pages Document Type: Essay Paper #: 52013195

Warehouse management is the control and optimization of the various processes in a warehouse. A warehouse management system (WMS) is an internal tool used to control and optimize the flow of materials. The functionality of the WMS is broken down into three operations; put-away, replenishing, and picking (Novák & Kraj?ovi?, 2011; Sahuri & Utomo, 2016). The basic principle for the WMS is directing the three operations to the relevant locations as per user defined criteria. A WMS can be a standalone or integrated with the organizations enterprise resource planning (ERP) system. This paper will focus on a standalone WMS and the discussion will seek to establish both software and hardware requirements for the server-end and client-end, then determine the competitive advantage for using WMS, provide recommendations for improvement and lastly, draw a conclusion.

Designing Compliance Within the LAN to WAN Domain

Words: 1148 Length: 4 Pages Document Type: Essay Paper #: 86952279

In order to ensure compliance within the LAN-to-WAN domain it is vital to have protective and security layers. Firewalls, intrusion detection systems, virus scanners, and other protective software would provide assurance that the security policies for the organization are implemented and adhered. Having multiple locations, there will be huge amounts of data that is transmitted between the four locations and this should not be interfered with in order to ensure that employees are able to perform their duties. Therefore, the security solutions implemented should also have a public key to encrypt and decrypt the data. Securing the four locations and allowing for data transmission will require an innovative and secure layout at all locations. Compliance within the four locations will ensure that the facilities are secure and they are operating within the laid-out security policy.
Proposed Solution
The firewall will act as the first layer of protection and filtering for…… [Read More]

Poor Quality Data and Equifax

Words: 1035 Length: 3 Pages Document Type: Essay Paper #: 15761488

Data in information systems allows for businesses to process various actions in a way that is seamless. If one imagines a business as a factory, many businesses main product is data. From hospitals to banks, data is created, stored, transferred, and viewed every single, work day. If this data is of poor quality, it may slow down a business’ processes. For example, a hospital’s medical records are still on paper and have not been transferred to a digital copy. Such an event can trigger easier data breaches and longer wait times for information to be retrieved, copied, and transferred.
What makes data quality poor? There are collectively defined standards that define data quality. They are accuracy, completeness, consistency, uniqueness, and timeliness (Kimball, Ross, Thornthwaite, Mundy, & Becker, 2011). When poor quality data is inaccurate like for example, the last name of a customer in a bank, this leads to service…… [Read More]

Application of Lean to a Help Desk

Words: 1264 Length: 4 Pages Document Type: Essay Paper #: 76076022

Lean
Overview of the Company
IT All-Stars is a managed service provider targeting small- and medium-sized enterprises. The service desk is the typical point of contact with customers, and a basic workflow begins when a customer has a problem. The customer submits a ticket, and then a technician works to solve the problem (i.e. Internet not working, person forgot password, etc.). The business model is that the company proactively manages the IT function for the client, so also does things like managing the hardware (i.e. replacing it when the warranty expires, servicing, managing domains, etc.).
Justification for Lean
A lean approach in services is utilized in order to streamline the delivery of routine processes. The objective of implementing lean is to ensure consistent service delivery through consistent process delivery, which in turn means that delivery will be faster, and more accurate. Faster response times mean happier customers, and when techs…… [Read More]

Compare the two managerial roles associated with successfully managed systems projects: the project sponsor and project champion.

The project sponsor is typically a senior executive who has the responsibility of accomplishing certain strategic objectives that are so wide in scope they require synchronization of many different parts of the organization. An example would be the development of an entirely new Customer Relationship Management (CRM) system that is capable of reporting back the contact and selling histories by each customer account. The project sponsor in this specific instance would typically be the Vice President of Sales, or the Vice President of Marketing. The project sponsor is also responsible for working with the broader organization to ensure the project has enough resources, both from a staffing standpoint in addition to support at the upper levels of management to ensure the project gets continued funding.

Further, midrange systems can support a few thousands users, and often have operating systems more focused on distributing resources throughout a network vs. being a computing-intensive system. While there is increasingly a focus in midrange systems to provide both distributive support for networks and computing power, the predominant use of these systems is in synchronizing the many databases a small to mid-size organization up to a few thousand users need. Mid-range systems have also become pervasively used throughout a variety of specialized uses, sometimes called vertical markets. The IBM as/400, one of the most popular midrange systems, has literally hundreds of thousands of applications that have been created just for a specific vertical market need.

Mainframes on the other hand are used for much more compute-intensive tasks including the completion of massive transaction sets and database calculations. A mainframe is typically used for also managing the entire array of integration…… [Read More]
