Dedicate this device to ReadyBoost vs. Use this device

ReadyBoost is a disk caching software component that was developed by Microsoft to make computers run faster. While running many apps and programs, much cache is generated which slows down your computer.  By using ReadyBoost, USB flash drives, SD cards, CompactFlash can be used to store cache between HDD and RAM, which increases the performance of a computer.

In order to enable ReadyBoost to your computer do this: Plug in your USB flash drive or SD card, open File Explorer, right-click on your device, select Properties and then go to ReadyBoost tab. Choose either Dedicate this device to ReadyBoost to use the whole device storage as cache or Use this device to adjust the amount of storage reserved for ReadyBoost.

WordPress user roles and permissions

WordPress uses a concept of Roles, designed to give the site owner the ability to control what users can and cannot do within the site.

In a WordPress site, there are six pre-defined roles: Super Admin, Administrator, Editor, Author, Contributor and Subscriber. Each role is allowed to perform a set of tasks called Capabilities.

1. Super Admin: Somebody with access to the site network administration features and all other features.

This user role is only available on a WordPress multisite network. Users with the super admin user role can add and delete sites on a multisite network. They can also install plugins and themes, add users, and perform network wide actions on a WordPress multi-site setup. Simply, they have admin access to every single site in the network.

2. Administrator: Somebody who has access to all the administration features within a single site.

Users with the administrator role can add new posts, edit posts by any users, delete those posts, and they can also install, edit, and delete plugins and themes. Apart from that they can add and delete users, and change information about existing users, including their passwords.

3. Editor: Somebody who can publish and manage posts including the posts of other users.

Users with the editor role in WordPress have full control on the content sections of your website. They can add, edit, publish, and delete any posts on the site, including the ones written by others. They can moderate, edit, and delete comments as well. However, Editors do not have access to change your site settings, install plugins and themes, or add new users.

4. Author: Somebody who can publish and manage their own posts.

Users with the author role can write, edit, and publish their own posts. They can also delete their own posts, even if they are already published. While writing posts, authors cannot create new categories, but they can choose from existing ones. They can also add tags to their posts.

Authors can view comments even those that are pending review, but they cannot moderate, approve, or delete any comments. They do not have access to site settings, plugins, or themes.

5. Contributor: Somebody who can write and manage their own posts but cannot publish them.

Users with the contributor role can add new posts and edit their own posts, but they cannot publish any posts. While writing posts they can choose from existing categories and create their own tags, but they cannot upload files, so they can’t add images to their posts. Contributors can also view all website comments, but they cannot approve or delete comments. These users don’t have access to website settings, plugins, or themes, so they cannot change any settings on your site.

6. Subscriber: Somebody who can only manage their profile and has just the “read” capability.

Users with the subscriber role can log in to your WordPress site, update their user profiles, and change their passwords. They can’t write posts, view comments, or do anything else inside your WordPress admin area. This user role is particularly useful if you have a membership sites, online store, or another site where users can register and log in.

What is a computer?

A computer is an electronic device that can be programmed, accepts data (input), processes it using a set of instructions, stores it, and gives information as the output. It is also an electronic device that performs calculations based on a set of instructions. The first computers were huge, room-sized machines that took teams of people to build, manage, and maintain, but the computer systems of today are extremely faster.

What is a computer system?

A computer system is a complete computer that comprises a collection of hardware, software and liveware; that are designed to receive, process, manage and present information in a meaningful format.

Therefore, a computer system consists of hardware, software components and liveware. Hardware is the physical equipment that includes the case, keyboard, monitor, cables, storage drives, speakers, and printers. Software includes the operating system and programs. The operating system manages computer operations such as identifying, accessing, and processing information while programs or applications perform different functions. Programs vary widely depending on the type of information that is accessed or generated. Liveware is the computer user that commands the computer system to execute instructions.
