Ultrabook is an Intel specification and trademark for a line of high-end subnotebook computers featuring reduced bulk without compromising battery life
5. WHAT IS THE ULTRABOOK?
It is a new kind of laptop marketed by
Intel, one the leading manufacturers of
computer processors.
Intel seeks to market the ultrabook as
the solution between tablet computers
and small laptops.
6. PHYSICAL CHARACTERISTICS OF AN
ULTRABOOK
Thin
An ultrabook should have a maximum
thickness of 21mm. Ultrabooks released
right now range around 16-18mm thick,
so there might be even thinner models in
the future.
7. PHYSICAL CHARACTERISTICS OF AN
ULTRABOOK
Lightweight
Since Intel seeks to bridge laptops and tablet
computers, an ultrabook should also be
lightweight. As such, an ultrabook should have a
maximum weight of 1.4 kilograms, or 3.1 pounds.
8. PHYSICAL CHARACTERISTICS OF AN
ULTRABOOK
Screen size
Ultrabooks seek to be slim, portable and mobile,
so screen size needs to be trimmed down.
An ultrabook should only come in 11 or 13 inch
screens. Anything smaller than 11 inches, then
it‘s considered a netbook. Anything bigger than
13 inches, then it‘s a normal laptop.
9. WHAT ARE THE OTHER
FEATURES?
An ultrabook doesn‘t have a disc drive. This allows
them to become thin and lightweight.
Ultrabooks seek to be powerful and fast too.
They have Intel processors of at least 1.6
GHz.
at least 5 hours of battery life. They should also
be able to boot up and restart very quickly.
Another thing that Intel states is that an
ultrabook should be affordable.
21. A solid-state drive (SSD) is a data storage device that
uses solid state memory to store persistent data and SSDs
use same I/O interfaces developed for hard disk drives.
SSDs use NAND-based flash memory or DRAM to store
data.
22. FORM FACTOR
Standard HDD form factors – is equal to size of traditional HDD form
factors like 3.5", 2.5”
2.55’’ HDD form factor
23. HOST INTERFACE
Serial ATA (SATA)
SAS - Serial attached SCSI (generally found on servers)
PCI Express
Fibre Channel (almost exclusively found on servers)
USB
Parallel ATA (IDE) interface (mostly replaced by SATA)
