Communication and information technologies

It’s inconceivable to think of our world without communication and information systems. They influence almost every aspect of our lives and develop at a pace that’s difficult to keep abreast of. This module will teach you to understand the fundamental technologies that underpin these systems and introduce you to a range of issues that arise from their deployment. You’ll develop management and information technologies skills, proficiency in communicating ideas and information, and your ability to keep up-to-date with new technological developments.

Modules count towards OU qualifications

Study level

Across the UK, there are two parallel frameworks for higher education qualifications, the Framework for Higher Education Qualifications in England, Northern Ireland and Wales (FHEQ) and the Scottish Credit and Qualifications Framework (SCQF). These define a hierarchy of levels and describe the achievement expected at each level. The information provided shows how OU module levels correspond to these frameworks.

What you will study

The module consists of three blocks – each covering a key area in communication and information technologies – and an individual project:

Block 1: Enquiring and communicating
The first block covers technologies that enable wireless and mobile communications such as Wi-Fi, mobile cellular networks and for the Internet of Things. You’ll develop study skills such as finding information online and reading, evaluating and writing technological materials. You’ll use and further develop these study skills in Blocks 2 and 3. You’ll also learn some practical skills through using network simulation software.

Block 2: Protecting and prying
Block 2 covers technologies for computer security and discusses privacy and ethical issues around the use of these security technologies. You’ll further develop your writing skill, especially for writing reports. You’ll also learn practical skills through activities on computer security.

Block 3: Interacting and collaborating
This block covers principles and technologies for collaborative work and interaction design. You’ll work in a group on a collaborative project: using the collaboration and interaction design principles studied in this block, you’ll design and build a web site. Collaborative work is the key study skill you’ll develop in this block.

Individual project
This project will form part of your final assessment. Using the knowledge and skills you’ll develop in Blocks 1–3, you’ll create a small web site explaining new developments in an area of communication and information technologies. This will include conducting a small literature survey to keep yourself updated with developments in the given topic.

You’ll develop digital and information literacy skills – which are very important for your study – throughout the module. You’ll develop academic and technical writing skills progressively from Block 1 to Block 3. You’ll also develop some practical skills in using specialist software, which can improve your employability.

You will learn

This module will:

  • increase your knowledge of the basic principles of communication and information systems and technologies, and the issues relating to their use
  • develop your ability to apply your understanding of communication and information technologies to learn about new or unfamiliar systems and technologies
  • develop a variety of skills appropriate to a practitioner in information and communication technologies
  • teach you work as a group, where the collaboration is via communication technologies.

Vocational relevance

The practical activities require the use of specialised software. The practical skill developed has a high vocational relevance.

In addition, the module develops important skills that are particularly relevant to the workplace, such as written communication, information literacy, numeracy, independent learning, critical analysis and team working.

Teaching and assessment

Support from your tutor

Throughout your module studies, you’ll get help and support from your assigned module tutor. They’ll help you by:

  • Marking your assignments (TMAs) and providing detailed feedback for you to improve.
  • Guiding you to additional learning resources.
  • Providing individual guidance, whether that’s for general study skills or specific module content.
  • Facilitating online discussions between your fellow students, in the dedicated module and tutor group forums.

Module tutors also run online tutorials throughout the module. Where possible, recordings of online tutorials will be made available to students. While these tutorials won’t be compulsory for you to complete the module, you’re strongly encouraged to take part.

Ways to pay for this module

Open University Student Budget Account

快猫视频 Student Budget Accounts Ltd (OUSBA) offers a convenient &/courses/modules/tm255/39;pay as you go&/courses/modules/tm255/39; option to pay your OU fees, which is a secure, quick and easy way to pay. Please note that 快猫视频 works exclusively with OUSBA and is not able to offer you credit facilities from any other provider. All credit is subject to status and proof that you can afford the repayments.

You pay the OU through OUSBA in one of the following ways:

  • Register now, pay later – OUSBA pays your module fee direct to the OU. You then repay OUSBA interest-free and in full just before your module starts. 0% APR representative. This option could give you the extra time you may need to secure the funding to repay OUSBA.
  • Pay by instalments – OUSBA calculates your monthly fee and number of instalments based on the cost of the module you are studying. APR 5.1% representative.

Joint loan applications

If you feel you would be unable to obtain an OUSBA loan on your own due to credit history or affordability issues, OUSBA offers the option to apply for a joint loan application with a third party. For example, your husband, wife, partner, parent, sibling or friend. In such cases, OUSBA will be required to carry out additional affordability checks separately and/or collectively for both joint applicants who will be jointly and severally liable for loan repayments.

As additional affordability checks are required when processing joint loan applications, unfortunately, an instant decision cannot be given. On average the processing time for a joint loan application is five working days from receipt of the required documentation.
