Week 13: 3.2.4 Videos.

I’ve saved a number of videos on this section in my delicious, so in order to access them easily, and in the order in which we cover them in this topic, (Find them under the tag bundle ‘networks’.) I’ve listed them below: (There will be some content overlap between them.)

1. Network basics: hardware including references to NIC, cable, hub. 

2. Several on other hardware: router_modem and a bridge.

3. Topologies. (Which includes reference to cable, or transmission media.)

4. Two separate videos on routing and protocols. (Animated – Warriors of the net)

5. Some cover network software: concept_of_AD&Extranets. (AD is short for Active Directory, a software service which enables the management of identities and relationships in a network.) AD domain software, creating groups & users and add_client. (The quality of the latter are not too good, but they’re still useful.)

6. Intranet_firewalls.

7. There are another few on: internet basics, TCP/IP, email_basics and email_basics2.

8. A number of videos cover VOIP, (Skype) WAP and wi-fi, including its potential dangers.

9. Satellite technology and the Russian answer to GPS.

Notes on this section can be found here, but you will definitely have to add current technology to the content. As you watch the videos, have the notes to hand and underline key words. Add notes and explanation to any topic or area not covered.

3.2.4 Hardware and Software

Today we’re going to spend some time looking at the different hardware and software which allows connectivity – cabled or wireless. Students should look for images to update many of the traditional pictures found. Discussion will include: network nodes, (computers, laptops, pdas, fax, plotter, printer etc.) servers, network cards and adapters, hubs, switches, modems, routers, bridges and repeaters. We’ll also discuss how the terms ‘proxy’ and ‘gateway’ have meaning in a  network.

We’ll have a brief discussion of networking software, and then on Monday take a look at what software our WGS Systems Manager Mr. Hancox has used to set up the network. He can develop a little further what the role and importance of this software is.

Network Construction

Today we’ll start by selecting the link in the previous post, ‘network construction’ and taking the ‘step by step’ approach to building a network. This will aid you in preparing for the main task for today:

  • Print off a copy of the schematic map of Wolverhampton Grammar School. 
  • Put on your coats and walk around the school, noting where and how many computers or ‘nodes’ (including printers and scanners) are in the various buildings or rooms around the campus.
  • Note where the Hubs or Switches are positioned – think of which computers they link up.
  • Using the schematic map, positioned in the centre of an A3 piece of paper, draw and label all the segments of the WGS network. 

Week 12: 3.2.4 Transfer of data in ICT systems

This week we’re going to begin a topic more commonly known as computer networking. It will take us the two weeks (12 & 13) to get through it. initially, we’ll look at the teach-ict website and discuss the following:

  • What is an ICT Network?
  • What is the difference between a LAN and a WAN?
  • What are the advantages and disadvantages of computer networks? 
  • Protocols, Topologies and Transmission modes
  • Hardware and Software for networks. (Consider mobile phones, pdas and other portable devices.)
  • The Internet and the WWW, including email and other methods of electronic communication.

A series of short videos on my delicious will illustrate some of the above, (dated 23rd November) and when they’ve been watched, you should attempt the interactive network construction on this link.

The powerpoint summary can aid revision of this section, as will the set of notes originally from fatmax and North Chadderton. Always use current textbooks as well, to update these for the new specification.

IT Professions

Using the link on the previous post, today we’ll look at and discuss various jobs in the IT industry. We’ll consider the skills, both personal and professional, one would need for the positions. Students should then draw up a table listing a range of jobs, salaries and descriptions.

Post lesson: Table 1 and Table 2. Have another look at the two job tables and see how many require working in a team, and how many reference personal traits or skills. If they haven’t, think what personal traits might be required.

Week 11: 3.2.3. Information and the Professional

We’re going to start the week by looking at notes on HCI (courtesy of North Chadderton) and by completing a short worksheet on this topic. 

The next topic under 3.2.3 looks at the different jobs, personal qualities and teamwork associated with being an ICT professional. We’ll follow this link and explore the different opportunities for those interested in pursuing a career in ICT and then complete another short worksheet on the topic. Use your textbooks as references, but a set of notes is also available.

The future of GUI

We’re going to have a look at a couple of short Youtube videos (dated 12th November) tagged under ASICT and future_gui on my delicious. They’re very interesting, but we’ll discuss whether they’re gimmicks or effective GUI’s which could assist users in the future.
