Question 5

Tablet/Hybrid Definition & 2 Advantages & 3 Disadvantages

Answer 5

Definition:
Tablet/Hybrid
Sometimes referred to as convertible or hybrid notebooks, a hybrid is like a regular notebook, but has a removable display that functions independently as a slate.

Advantages:
1. Hybrid Computers are very fast making them useful for numerical calculations and flight simulation

2. A hybrid computer combines the desirable features of analog and digital computers. It is mostly used for automatic operations of complicated physical processes and machines.

Disadvantages:

1. Hard To Use For Beginners
2. Might Misplace the display
3. The Battery is implemented into the display making it heavy to hold as a hybrid tablet

Question 6

Advantages (LEARN 3)
1. It usually small

2. Designed for a specific purpose
3. Has one or more micro-processor/controller
4. It may or may not be part of a larger system
5. Based on the application may or may not have
   input/output, memory, connectivity
6. It’s everywhere from your home to space shuttles
7. Some are designed to perform time critical operations like in aircrafts, where a small delay can cause a disaster.
8. Depending on application it may or may not contain an operating system. Commonly used operating system, embedded linux

Disadvantages:

1. Cost - Phones are becoming really expensive
2. Smartphone Addiction
3. Sleep Deprivation has been linked directly to heavy use of smartphones
4. Repairs to smartphones can be expensive

Answer 14

1. Can Calculate millions and millions of problems each second
2. Can process huge amounts of data very fast
3. Can Manage huge amounts of computers at once.
4. Great for big business with huge databases like airlines eg. Emirates (EK), British Airways (BA)

Question 15

Mainframe Disadvantage?

Answer 15

1. Mainframe Systems are extremely expensive
2. You will need to hire trained professionals to keep an eye on the system
3. Mainframe Systems are very large and are not meant to be moved around
4. Quite a lot of money needs to be spent on keeping the mainframe systems cool to make them stop overheating, if this is not done the room where the system is located becomes a fire risk.
