Q

What are the 3 types of secondary storage devices?

Study These Flashcards
A

Magnetic storage- hard disk drives.
Optical storage- CD, DVD and Blu-ray
Solid state- USB memory sticks and solid state drives

23
Q

What are magnetic hard disk drives?

Study These Flashcards
A

They store data by representing bits as a magnetic polarity. They are mechanical so are relatively slow and are easily damaged because of moving parts which are likely to malfunction.

24
Q

What are the benefits of magnetic hard disk drives?

Study These Flashcards
A

The company servers will have backup and security in place. If the laptop is lost the data isn’t lost. It would allow the employee to do their work on different computers.

25
What are the drawbacks of magnetic hard disk drives?
The servers may only be available in the company building so work done outside won’t be saved immediately. The company would have to invest in specialist servers and IT support staff.
26
What is solid state (Flash) storage?
Used logic gates to store data. No moving parts so it’s faster and more robust than traditional hard disk storage. However, it is more expensive. Mobile devices tend to use this type of storage although laptops can use a combination of solid state and hard drive storage.
27
What are the advantages of solid state (flash) storage?
There is no need to be connected to a network. SSDs are robust so would be less prone to damage or loss if the laptop is dropped.
28
What are the disadvantages of solid state (flash) storage?
If the laptop is lost, stolen or seriously damaged, the data may be lost if no backup has been made. The drive may reach capacity if a lot of work is stored. If there is no security then the data could be stolen or copied.
29
What is cloud storage?
Your mobile provider: Apple, google, etc. often provide you with the option of storing data online. The servers themselves will use a combination of hard drive and solid state storage to actually store the data.
30
What are the advantages of cloud storage?
Provider takes care of security and backups. Allows you to store more data than your device can hold. Makes it easier to share and collaborate on work. Data stored off site. Access remotely.
31
What are the disadvantages of cloud storage?
Requires access to the internet. Reliant on third party company to keep data safe. Cloud services are more visible and therefore prone to hackers trying to attack and steal data. May be expensive.
32
What are peripheral devices?
Devices that are not the computers core architecture.
33
What are some examples of input peripheral devices?
Mouse, keyboard, webcam, microphone and games controller.
34
What are some examples of storage peripheral devices?
Hard drive, SSD, external disc drive, optical drive and graphics card.
35
What are some examples of output peripheral devices?
Monitor, printer, speakers, headphones and projectors.
36
What is manual data processing?
When the data is processed manually by a human.
37
What are some examples of technology that requires manual data processing?
Keyboard, numeric keypad, joystick, pointing device, remote control, touchscreen, scanner, graphics tablet, microphone, webcams, light pens and a digital camera.
38
What are the advantages of manual data processing?
Can enter lots of different types of data at once. Likely to spot avoidable errors. Job creation/retention. Ideal for certain types of jobs where accuracy is essential.
39
What are the disadvantages of manual data processing?
Slow speed of data entry. Easy to make mistakes. High cost of training staff. Possible system security issues.
40
What is automatic data processing?
When the data is performed by a digital device/ electronic machine.
41
What are the advantages of automatic data processing?
More accurate as not prone to human error. Much faster as data can be processed in large quantities. Saves money (over time).
42
What are the disadvantages of automatic data processing?
Makes people redundant. Initial investment costs. Can be limited to processing one type of data e.g. text.
43
What are some examples of automatic data processing devices?
Barcode scanner, RFID reader, RFID emitter, optical mark reader, QR codes, GPS devices.
44
What is RFID?
All contactless cards have a small microchip inside them and the tag contains an integrated circuit and an antenna which are used to transmit data to the RFID reader. The reader then converts the radio waves to a usable form of data. Commonly used for fobs, cards, smartwatches and contactless payment.
45
What is magnetic ink character recognition (MICR)?
The numbers at the bottom of the cheque are written in special ink which contains iron particles. This ink is magnetised and commonly called 'magnetic ink'. It can be read by a special machine called a magnetic ink character reader (MICR). Commonly used in banking.
46
What is an optical mark reader (OMR)?
A scanning device that reads carefully placed pencil marks on a specially designed form or document. The completed documents are scanned by an OMR which detects the presence of a mark by measuring the reflected light. Less light is reflected where a mark has been made. Common use in exam papers and lottery tickets.
47
What is optical character recognition (OCR)?
Enables the computer to identify written or printed characters. It consists of a normal scanner and some special software. The scanner is used to scan the text from a document into the computer. The software then examines the page and extracts the text from it, storing it in a form that can be edited or processed by normal word processing software.
48
What is a Global Positioning System receiver (GPS)?
A GPS receiver is constantly listening for signals from 30+ GPS satellites that orbit the earth. The receiver figures out how far they are away from some of them. Once the receiver calculates its distance from four or more satellites, it knows exactly where you are within a few feet. Common uses such as for navigation on cars and smartphones.
49
What is application software?
Software to help the user get jobs done; e.g. a word processor would be an example of application software.
50
What are some examples of types of application software?
Word processors (word, docs), spreadsheet, presentation, database, graphics, games, web browser, social media.
51
What is system software?
Software to help control the computer- operating system, utility programs are examples of system software.
52
What is general purpose software?
Software such as word processor, spreadsheet or graphics packages can be used for many different purposes. E.g. Graphics produce animation or manipulate photos.
53
What is special purpose software
Performs a single specific task or set of tasks. Examples include payroll and accounts packages, hotel booking systems etc.
54
What is off the shelf software?
