## 3.4. Meeting Minimum Hardware Requirements

Once you have gathered information about your computer's hardware, check that your hardware will let you do the type of installation that you want to do.

Table 3.2. Recommended Minimum System Requirements

Install Type | RAM (minimum) | RAM (recommended) | Hard Drive
--- | --- | --- | ---
No desktop | 128 megabytes | 512 megabytes | 2 gigabytes

The actual minimum memory requirements are a lot less than the numbers listed in this table. Depending on the architecture, it is possible to install Ubuntu with as little as 60MB (for amd64). The same goes for the disk space requirements, especially if you pick and choose which applications to install; see Section D.3, “Disk Space Needed” for additional information on disk space requirements.

It is practically impossible to give general memory or disk space requirements for server installations as those very much depend on what the server is to be used for.

Remember that these sizes don't include all the other materials which are usually to be found, such as user files, mail, and data. It is always best to be generous when considering the space for your own files and data.

Disk space required for the smooth operation of the Ubuntu system itself is taken into account in these recommended system requirements. Notably, the `/var` partition contains a lot of state information specific to Ubuntu in addition to its regular contents, like logfiles. The dpkg files (with information on all installed packages) can easily consume 40MB. Also, apt-get puts downloaded packages here before they are installed. You should usually allocate at least 200MB for `/var`.
