Computer Systems Flashcards
Name The 6 Types Of Computers?
- Desktop
- Tablet/Hybrid
- Mainframe
- Quantum
- Embedded System
- Smartphone
3 Desktop Advantages (ANY 3 OF THE 7)
- Lots of memory space
- Easy to upgrade
- Fast processors
- No battery
- Large screen ( depending on the monitor)
- Cheaper than laptops and tablets
- The monitor, keyboard, mouse, etc
3 Desktop Disadvantages (ANY 3 OF THE 5)
- Large carbon footprint
- Need keyboard, mouse and monitor (As separate devices)
- Big and heavy
- can be noisy
- not portable
What Is the Purpose Of A Desktop?
is to have a personal computer in a centralised location.
Tablet/Hybrid Definition & 2 Advantages & 3 Disadvantages
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
- 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:
- Hard To Use For Beginners
- Might Misplace the display
- The Battery is implemented into the display making it heavy to hold as a hybrid tablet
What Are The Features Of A Smartphone, 3 Advantages and 3 Disadvantages
What Is A Smartphone Used For?
Display, Camera and Video, Hardware Sensors, Wireless Data Access
Advantages (LEARN 3)
1. It usually small
- Designed for a specific purpose
- Has one or more micro-processor/controller
- It may or may not be part of a larger system
- Based on the application may or may not have
input/output, memory, connectivity - It’s everywhere from your home to space shuttles
- Some are designed to perform time critical operations like in aircrafts, where a small delay can cause a disaster.
- Depending on application it may or may not contain an operating system. Commonly used operating system, embedded linux
Disadvantages:
- Cost - Phones are becoming really expensive
- Smartphone Addiction
- Sleep Deprivation has been linked directly to heavy use of smartphones
- Repairs to smartphones can be expensive
Embedded System Definition?
An embedded system is a computer system with a dedicated function
Embedded System Advantages?
- Low Cost
- Ease Of Use
- High Reliability
- Easy To Manufacture
- Fewer Interconnections
Embedded System Disadvantages?
- Hard To Maintain
- Does Not Evolve With Technology Improvements
- Hard To Backup embedded files
- Hard To Carry Files From One Machine To Another
Quantum Computer Definition?
Quantum Computing uses the Quantum physics to increase the horsepower beyond a traditional computer could ever achieve
Advantages Of Quantum Computing
- The Time and Processing Speed Of A Quantum Computer is super fast
- (AI) Artificial Intelligence will allow large amount of operations to happen in a short amount of time
- We can create complex algorithms and sequences
Disadvantages Of Quantum Computing
- Hard to control quantum particles
- Lots Of Heat Expensive to cool down
- Expensive
- Difficult to build quite niche
Mainframe Definition?
A large powerful computer used to handle company wide information
In the form of databases
Mainframe Advantages?
- Can Calculate millions and millions of problems each second
- Can process huge amounts of data very fast
- Can Manage huge amounts of computers at once.
- Great for big business with huge databases like airlines eg. Emirates (EK), British Airways (BA)
Mainframe Disadvantage?
- Mainframe Systems are extremely expensive
- You will need to hire trained professionals to keep an eye on the system
- Mainframe Systems are very large and are not meant to be moved around
- 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.
