Description of the a Computer and how you use it
A computer by the oxford dictionary is described as “A device that computes, especially a programmable electronic machine that performs high-speed mathematical or logical operations or that assembles, stores, correlates, or otherwise processes information.” However they are more then this , today we can play games, listen to music, watch video, watch TV, create documents , manipulate images and browse the web , the ability of the modern computer is unlimited. A computer is controlled usually by two devices called a mouse and a keyboard, the mouse controls the movement of a cursor which allows you to point and click on objects to create reactions, the keyboard is used to input commands into the computer often in the form of numbers or letters. The output is displayed on a monitor which allows u to view what the computer is currently doing. Monitors are usually TFT screens but older makes have generic CRT ones.
The computer meets my needs as not only does it provide me with a huge array of entertainment options but also allows me to communicate with my friends and find out information and process it almost instantly.
Disadvantages of the computer
The main disadvantage of the computer is that it is fairly large and needs several pieces of kit to make it work effectively. The second is that the computer requires power from the mains meaning it cannot be moved while in use. This can be overcome by using a laptop which is powered by a battery which is recharged. Due to the internet many people often have the personal information exploited by hackers who illegally retrieved this information.
Improvements
The main improvements that should be made to the computer is the ability to voice command as this would reduce the time taken to type documents and carry out tasks.
Why I use satellite TV:
Satellite TV provides the ability to view huge amounts of channels from one place. It also means that there is more choice for the user and almost everyone’s personal interests can be accommodated for by using specific channels to broadcast specialised programs. Some of the advantages of Sky are:
- Easy to use TV Guide
- Over 1000 Channels
- Record up to 2 shows at the same time
- Built in hard disk so no need for video tapes
Description of SKY and how you use it:
SKY TV works by using a satellite in space which broadcasts all the channels to the whole of the UK this is picked up by a receiver on top of your house and is then converted into a picture by the SKY set top box. The advantage of this over normal cable TV is that there is no need to dig up your drive to lay a cable which could become damaged at a future date. It also provides a much higher quality picture and sound. You use sky simply by typing in the channel number which then switches to the channel. This is done via the remote control. There is also a TV guide which allows you to view what is currently showing on each channel and then allows you to select it. There is also a planner facility which means u can schedule a program to be recorded at a later date and there is a series link function which means you can record an entire series if that’s what is required.
How SKY meets my needs
SKY has a vast selection of channels which show almost every type of show. This fulfils all my entertainment requirements. However there is more as it also allows me to plan my viewing timetable and rent movies through the box office feature where I can pay per view. There is an interactive feature which allows you to by lottery tickets and accesses the internet.
Disadvantages of SKY
The biggest disadvantage of sky is that when there is overcastted sky the signal from the satellite to the receiver becomes blocked and you are unable to view the TV in such conditions.
