2. Exactly what is personal computing?
Personal computing affords the user the ability to carry on with their
computational responsibilities in the office or on the go; wherever one happen
to be. These tasks can be personal , business or as so often the case, a
combination of both. Activities include writing papers or creating exams;
checking and sending emails or Tweets, checking, setting or conducting
calendar activities such as exams, office hours or student support

3. Getting to Know Your Computer

•
Desktops vs. Laptops vs. Tablets vs. Smartphones
CPU’s-Central Processing Units
Memory-RAM-Random Access Memory
Storage-HDD-Hard Disk Drive
Display-Monitor-Computer Screen LCD vs CRT
Operating System-Microsoft Windows
– Windows 8
– Windows 7
– Windows Vista
– Windows XP
– Windows 2000, ME, 98 & 95

4. Definitions-CPU
• CPU(Central processing unit)- This is the brains
of the computer and its power is generally
measured in clock speed (cpu cycles). Today’s
CPU’s clock speeds will exceed 3 GHz on
desktops and 2 GHz on laptops.
• Caveat-Rated clock speeds are not linear
measurements- a 3.4 GHz Core 2 is actually
less powerful than a 3.2 GHz i5

5. Definitions- Memory
• Memory (RAM)- non permanent storage
measured in megabytes (MB) or preferably,
gigabytes (GB). Desktops should have at least 4-8
GB of RAM while laptops may have 1 GB but
should have 4+ GB of RAM
• Caveat- Windows XP can only recognize 3.28 GB
of RAM. Anything more is wasted. Windows 7 & 8
(32 bit) can recognize 4 GB and Windows 7 & 8
(64 bit) can recognize 192 GB

6. Definitions-Storage
• Permanent Storage (Hard drive) – Unlike RAM,
data stored in permanent storage remains
after the power is turned off. Storage, like
RAM, is measured in gigabytes (GB). Desktops
should have at a minimum 1 TB of storage
while laptops may suffice with 500 GB
• Caveat- If you plan to store pictures, videos or
music, you should opt for as much storage as
possible (terabyte plus)

7. Operating System
• Windows is the predominant operating system found on
PCs
– Windows XP-released October 30, 2001 and is currently the
most widely installed PC operating system (est. >400 million
worldwide)
– Windows Vista-released January 30, 2007 and has been plagued
by problems ever since its release
– Windows 7- released October 22, 2009 purportedly to fix all
past mistakes (installed on all new, major brand computers)
– Windows 8-released on August 1, 2012 is a touch-centric
operating system designed with mobile device integration in
mind. The lack of the Start button drew such criticism that
Microsoft released an update, Version 8.1 on October 13, 2013
which returned certain Windows 7 features such as the Start
button

8. Definitions-Desktop
• Desktop computer-May consist of five or more
components; but may also be of an all-in-one design
– Main frame or box which houses the CPU, memory,
permanent storage, DVD or CD drive, video adapter, sound
adapter, Ethernet connector, keyboard, mouse, speakers
and display
– Non-portable configuration whose components may weigh
more than twenty pounds

10. All-In-One Desktop Computers
Acer, HP, Lenovo and Samsung

11. Netbooks, Notebooks and Laptops
• While tablets and smartphones are in and of
themselves wonderful mobile devices, some
applications require the power, capacity and
flexibility of a classic desktop. Presently
netbooks, notebooks and laptops offer these
desktop features in a mobile mode.

12. Netbooks
Typically netbooks are set apart from tablets by the presence
of a tactile keyboard and a folding case. The processing
power, storage capacity and peripheral devices are limited by
their size

13. Notebooks

14. Laptops
• Laptops tend to be the largest and most
powerful of the portable computers often
boasting processing power, memory, storage
capacity and displays rivaling those of many
desktops.

15. Tablet Computers
• Tablet computers are an evolution of the
portable-laptop-notebook computer and have
been around for several years. Lately,
innovations in technology have allowed for an
extreme compression of computing power
into previously unheard of smaller sizes.
Improved computing circuitry, more efficient
heat release and greater storage capacity have
all melded together to create this new breed
of computer.
