Task 1
CPU – The CPU of a computer stands for ‘Central Processing Unit’. Many people know this as the brain of the computer
RAM – The RAM of a computer stands for ‘Random Access Memory’. The computers temporary memory is stored here.
Hard Drive – The Hard Drive is used to store files and folders.
Graphics Card – A Graphics Card is used by the computer to generate images onto your Screen (Both 2D and 3D)
Power Supply – A Power Supply is used to power your device and keep it running.
Screen – A Screen is used to show the images generated from your Graphics Card. Optical Drive – An Optical Drive is used to read and/or write information onto as disk such as CDs, DVDs and Blu Rays.
Software – A Software is a program that is put on your Device
Task 2
CPU – The CPU is vital to your device as it processes information which then executes a program that is loaded onto your computer. The better your CPU means the faster files and software will load on your computer. RAM – As stated before, all temporary memory is located in the RAM, once your computer is turned off, the RAM is reset and you lose all the data stored in it. If you have a larger RAM then more memory can be stored from your computer. Hard Drive – The larger the size of the Hard Drive, the more files and folders you can put on it. The sizes of Hard Drives can vary from 1GB (Gigabyte) up to 6TB (Terabyte) Graphics Card – A Graphics Card can be installed onto the motherboard, but it can also be installed separately if you want a better experience for things such as gaming. Power Supply – The Power Supply uses DC power, which it gets by taking AC power from an electrical socket. Once the power supply is removed then the device will turn off automatically until it is placed back in. You will then lose anything that is not saved such as work, as well as the memory inside the RAM. Screen – A screen shows the images generated from the graphics card. The screen is measured in inches, however the larger your screen doesn’t always mean that you will get better quality images. This depends on your screen resolution, for example the quality will be better for a FHD screen (1920 x 1080) than it will be on a HD Screen (1366 x 786) Optical Drive – As said before, this reads or writes information onto a disk. This is important because if you were to load up software, in some cases you will need to use a disk to install it. Software – Without any software then there is no point in using your device as you will not have anything to use your computer for. One type of software is an operating system, such as Windows 8, and Linux. Another software is all Microsoft Office products, you will need these to write up assignments on your computer.

Also both of these come with 3 USB ports, however the Acer only has 1 3.0 port and 2 2.0 ports, while the HP has 2 3.0 ports and 1 2.0 port. This then means that if you were to put in an external hard drive, files will move from it faster on the HP.
Both of the laptops also come equipped with an optical drive, however neither read Blu-Rays. As well as this, they both come with a Camera and Microphone so if you are away from friends/family then you can easily video call then, but on the HP there is a better webcam that has up to 5.7 megapixels, compared to the Acer which only has 1.3 megapixels.
As for security the HP doesn’t have anything, simple as that. However the Acer comes with a security lock slot, but unless you actually buy a security lock for the laptop, it is
