What information is shown in project management software
- Timeline
- Task Breakdown
- Resources required
- Milestone
- critical path
What are the advantages of using design view in Web Authoring Software over Code view
- WYSIWIG
- Reduces Human Error
- No need to learn or memorize any code
- Easier to rearrange items.
Why does a fragmented Hard Drive slow down the system
Some systems store programs and applications wherever there is free space left on the hard drive. This causes data to be fragmented.
Fragmented data can be stored in different locations in a platter, different platters in a cylinder or even different disks. When the data has to be retrieved, it has to be retrieved from these multiple locations, causing a reduced speed of data retrieval and slow down of application loading times.
What does disk defragmentation software do
This type of software re-orders the fragmented data so that they are as close to each other as possible, which increases the data transfer speeds
What is a general purpose computer
These computers are able to perform a range of tasks and run different types of software. Ex : Laptops, tablets or smartphones.
What is a single purpose computer
These computers are able to only run one specific piece of software. Ex : washing Machine, Dish Washer.
What are the different types of software
- System Software
2. Application Software
What is system software
These are types of programs that are able to maintain and operate the computer system
What is application software
These are programs that are used to allow the user to perform specific tasks. Ex : writing essays using word processing software.
What is utility software
These are a form of system software that carries out configuration and maintenance tasks.
What is an Operating System
These allow the user to control and manage the hardware of the system
What are the types of utility software
- Backup software
- Disk defragmentation
- Compression
- Formatting
- Anti-malware
Why is not recommended to defragment an SSD
Because an SSD stores data as electrical charges and they do not have any moving parts. So the computer’s access speeds will not change.
When you defragment an SSD it will also reduce the number of write cycles you will have for the SSD and reduce it’s life span.
This is why many operating systems do not allow the user to defragment their SSDs and offer another utility called trimming, which does not result in a loss of write cycles.
What is compression software
This is a type of software that is used to reduce file sizes and increase storage space on a storage device.
What does formatting utilities ask the user before formatting a storage media
- File system
- File Unit Size
- Name of the disk
- Confirmation from the user to format the media
What are the 2 types Operating Systems
- Single-purpose operating systems
2. Network Operating Systems
What are single-user operating systems
These Operating systems are made for a general user to use it and do not provide the option to customize for different users.
What are network operating systems
These provide additional features like :
- Being able to send usernames and passwords to an authentication server for authentication.
- Separating user accounts so that users cannot access each other’s data.
- Sharing network resources with other clients. Ex : shared network peripherals, network storage, shared applications.
What is the meaning of Authentication
This is the process of CONFIRMING that a user is permitted to access certain computer file, hardware and software.
What are the tasks that an operating system can perform and explain each
- Print Spooling:
This is when the operating system orders the print jobs that a computer sends to a printer into a que so that the printer is not overloaded with print requests. It arranges the print jobs into a queue faster than the printer produces printouts. - Memory Management
This is when the operating system allocates a certain amount of RAM to a particular program. Then after that program closes, that memory space is allocated to a different program. - Resource Management
The operating system also manages resources. These can include internal components like : RAM, CPU or GPU and external components like : printers, scanners. The operating system allocates certain resources to certain programs and if it is already in use by another application then the OS says that it is in use. - Security
The operating system mange security using : logins and passwords, Firewalls, biometrics. They provide secure access to a computer’s hardware. They provide firewalls as software to prevent network data from remotely being accessed by unauthorized users.
Types of application software ?
- Office productivity tools (word processing SW, DBMS, Spreadsheet SW)
- Web Authoring Software
- Image editing software (graphics editors and photo editors)
- Sound editing software
- Presentation Software
- Control software
- Project Management Software
- Communication software (Email, Web browsers, social media)
What are the types of software licenses
- Open source or free software
- Proprietary licenses
What are the key points in opensource software
- Provide source code
2. Free from usage rights, allowing the user to freely distribute the software
What are the key points in proprietary software
- Marketed under a brand name
- Does not give source code.
- Users have to obey usage rights.
