Basic Management of Computer Systems
What routine tasks keep a computer running well?
- Create and manage a user account
- Use Task Manager to monitor CPU, RAM and disk
- Check for and apply system updates safely
Overview
'Managing' a computer is a set of small routine tasks — creating a user, watching resource use, ending a frozen program, keeping the OS up to date. Each one is easy on its own; done regularly, they prevent most of the problems users complain about.
User accounts
Every person who uses the machine should have their own account with the right level of access. In Windows: Settings → Accounts → Family & other users → Add account. Standard users can work; only administrators can install software.
Monitoring performance
Open Task Manager (Ctrl+Shift+Esc). The Performance tab shows CPU, memory, disk and network use. The Processes tab lists what each program is using. A program that will not respond can be ended here.
Updates
Windows Update patches security holes and fixes bugs. Settings → Windows Update → Check for updates. Updates should be applied regularly — never delayed for months.
Lab practical — three routine tasks
- On a lab PC, create a standard user account named test-user.
- Open Task Manager and record CPU, RAM and Disk % at rest.
- Check for Windows updates and note how many are pending.
- Tick each task on the practical checklist.
- Which shortcut opens Task Manager?
Reveal answer
Ctrl + Shift + Esc.
- Why should each user have a separate account?
Reveal answer
So files, permissions and history are kept private and admin rights are limited.
- Why do updates matter?
Reveal answer
They fix security holes and bugs before attackers can exploit them.
At home, open Task Manager and list the top 3 programs using memory. Which of them do you actually need running?
