Study Notes
Hardware Lifecycle Stages
- Procurement: Acquiring new hardware
- Deployment: Installing and configuring hardware
- Maintenance: Regularly checking, fixing, and updating hardware
- Retirement: Disposing of old or unusable hardware
IT Infrastructure
- IT infrastructure is essential for any organization
- Without it, employees cannot work and the company cannot function
IT Roles
- Sysadmin: Manages and maintains computer systems and networks
- DBA: Manages database systems
- Network Administrator: Manages network infrastructure
- Security Administrator: Manages security systems
- Web Administrator: Manages web servers and websites
Server Types
- Tower: A server that looks like a desktop computer
- Rack: A server designed to be mounted in a rack
- Blade: A thin, high-performance server housed in a chassis
- Desktop: A server designed to be used on a desk
- Email Server: A server that sends and receives emails
- Web Server: A server that hosts websites
Computing Types
- Local Computing: All data and processing occurs within a company's premises
- Cloud Computing: Data and processing are managed remotely by third-party providers
Benefits of Local Computing
- Complete control: Organizations have full control over their infrastructure
- Potential cost savings: Long-term costs may be lower than cloud solutions
Drawbacks of Local Computing
- Potentially higher initial costs: Building and maintaining infrastructure can be expensive
- Limited accessibility: Access to resources is restricted to the location of the infrastructure
Benefits of Cloud Computing
- Scalability: Easily adjust resources based on need
- Accessibility: Services are available from anywhere with an internet connection
- Cost-effectiveness: Lower starting costs and potentially lower ongoing costs
- Software updates: Updates are handled by the cloud provider
Drawbacks of Cloud Computing
- Security concerns: Data is stored off-premises
- Dependency: Organizations rely on third-party providers
- Potential cost increases: Long-term costs may exceed local computing
KVM Switch
- A device that allows a single keyboard, mouse, and monitor to be connected to multiple computers
Computer Policies
- Establish rules for computer use in the workplace
- Examples:
- Allowing or disallowing users to access non-work-related websites
- Allowing or disallowing users to install software
- Setting password requirements
Offboarding Employees
- Remove access to IT resources
- Wipe the employee's device
- Ensure all company data is removed
IT Infrastructure Lifecycle Stages
- Deployment:
- Setting up user accounts
- Installing software
- Maintenance:
- Replacing hardware with existing inventory
