Along with models and brief price explanations!


HDD stands for hard disk drive and is a computer's main means of storage. Designed in the 1980, most computers have a HDD. The HDD consists of a disk that stores bits of data and constantly spins. It also consists of two heads, one to write the bits onto the disk and one to read the data. The HDD is non volatile meaning it will still store memory through it's magnetic strips even when electricity is not present.

Attributes of the HDD

The disks in the HDD constantly rotate. Depending on the RPM(revolution per minute) we can tell which HDD model is faster. The faster the RPM, the faster the HDD can access stored data.

Size of the HDD is also important. Some smaller HDD can only hold up to a couple hundred GB while others can hold up to several TB.


Solid State drive is a more modernized component of a computer that is also used for storage like the HDD. The SSD however does not include a moving disk, hence the name solid state and thus is quieter during the startup of the computer, faster during startup and faster at reading stored data. The short way of putting it, SSDs are improved version of the HDD.

Attributes of the SSD

Size and storage of the SSD can vary from a couple GB to several hundred. Unlike the HDD, most SSD including the expensive models will not hold as much as a TB

Shock resistance is the resistance against physical damage against the SSD and is measured in g units. The calculation of the shock resistance involves the science of gravity and acceleration. To be explained simply, a good SSD will have a shock resistance of around 1500g which means it can survive a 6 foot fall and most physical abuse it goes through over the course of it's life.

SSDs are replacing HDDs as the primary storage device that comes with any computer.

model and prices:SSD

1)Budget conscious models can be found at a 100$ price range but will only store about 100GB

2)Average model/brand includes SanDisk ranging price range from 200-400 dollars and a memory of 200-400 GB respectively.

3)High end model includes Intel brand 320 Series reaching a high 600 GB capacity with a 600-800 price range.

The SDD beats the HDD in most attributes that the average user values.

Mouse and Attributes

A peripheral device that may or may not be used alongside the keyboard to assist a user in their computer usage experience. The mouse is not an integrated part of the computer.

Attributes defining a mouse includes:

Technology used in the bottom of the mouse. Some mouses have a ball that rolls upon moving the mouse while others use optimal technology which uses a beam to sense the movement of the mouse.

Amount of buttons found on the mouse. Most mouses have 2 buttons although some mouses may have only 1, 3 or several buttons, each assigned to a specific shortcut.

Whether the mouse is chorded, wireless or connected to the computer via bluetooth.

Keyboard and Attributes

The keyboard is a peripheral device that serves as the primary input device of the computer. The keyboard may or may not be integrated onto the computer. It includes the letters of the alphabet, numbers from 0-9, modifier keys such as: alt and control, and function keys (F1-F12).

Attributes distinguishing the keyboard:

Some keyboards come in larger sizes because they include a keypad on the right and perhaps a touchpad. Keyboard laptops that are integrated might have smaller keys and a backlit function unlike a seperate keyboard.

The means of connecting the keyboard to the computer is another attribute. Some keyboards are chorded, others integrated and some wireless and blutetooth.

Models and prices: keyboard

1) budget conscious model: 10-20$ keyboard likely thick and chorded. Chorded mouse will be cheaper than wireless

2)average budget can aim for a wireless mouse or keyboard with thinner keys at a 50-100$ price range Some keyboards come with a touchpad which will take away the need for a mouse.

3)high end keyboards can run up to 1000$ dollars, wireless, bends together for portable movement and to mold into the user’s liking, touchpads to replace the mouse and keys that are flat and uses touchscreen similar technology.


Speakers are audio output devices that can be connected via bluetooth or port. Speakers takes input in the form of audio waves and converts it into soundwaves. A speaker's performance can be measured by it's frequency handling and amplitude. Frequency refers to the length of a sound wave which defines whether something sounds high and soprano or low and deep. Amplitude simply refers to how loud the speaker can play.

Attributes of a speaker may include the amount of cones a speaker has. A speaker may have several cones, each a different size and made to handle a certain frequency range.

Speaker attributes can also include the amount of speakers in a set. Some speaker sets include several speakers with the purpose of separating left and right sound channels.

Models and prices: speakers

  1. budget concious model of mini portable speakers that come in pairs and have one cone each for 10-50$

2. average budget model for around 60-150 $ will include speakers with 2 or more cones for better frequency range. Comes in pairs

3. high end budget speakers will include multiple speakers with several cones each to provide surround sound and handle soprano level frequencies ranging from 1000$
