OCR Cambridge Nationals in ICT (Level 1/2)
R009 Exploring Computer Hardware and Networks
3
Components
Computers are made up of different components
that work together.
  • Inside the average PC or Mac you will find
  • RAM
  • ROM
  • a hard disk
  • a DVD player
  • a main board
  • various cables
  • a screen
  • a keyboard.

When these are all working together, the computer
functions well.
4
Mobile Technologies
Devices such as the Kindle, Nintendo DS and MP4
players allow for mobile entertainment to be
readily accessible.
In recent years, computing has moved away from
the large desktop.
5
Games Consoles
Combine a console with a home network and
services such as Xbox live widen the gaming
experience to a global scale.
Most UK homes have a games console allowing for
streaming video, movement gaming, music playback,
photo displays and online purchasing.
6
Network Topology
Networks are found in the majority of businesses
and many homes have smaller networks now.
Wired networks can be set up in different ways
such as Star and Hierarchical.
Virtual servers and thin client computing have
reduced the cost and increased the speed for
modern networks.
7
Types of Network
Networks are found in homes, offices, schools,
hospitals and in many other places.
Wireless networks are now used to attract
shoppers and the mobile telephone networks grow
larger every year.
Selecting the right kind of network for the
organisation and then setting it up takes
specialist skills.
8
Computer repair
Knowing what to look for is as important as
knowing how to fix the problem.
Like all things, computer hardware fails at
times. Some things can be fixed with a minimum of
technical support whilst others require an IT
expert.
Computer or connection problem?
Repair or replace?
9
Network issues
When a network component fails or is wrongly
configured it can lead to a loss of productivity
and profits.
Completing diagnostics and knowing how to perform
the right tests will help the users get up and
running again quickly.
Which cable? What server? WEP or WPA? Is the
route clear? Are the lights flashing?
10
  • You will learn

Assistive technologies for specified needs.
What it means to be an ICT technician supporting
users.
IP addresses, MAC addresses and network types.
LANs, WANs, IDs, CAT5, WiFi and PING.
Computer hardware components and how they work.
Common computer problems and how to fix them
