Describe how integers are represented in a computer?
Integers are represented as a string of 1's and 0's. The bits (a single one or zero) are weighted by powers of two, so the one on the far right has value 20 or 1, the second is 21 or 2, third is 22 or 4, 4th is 8, 5th is 16, etc. An integer in a modern computer is typically 32 bits long, or 4 bytes (a byte is 8 bits).
Negative numbers are represented in two's complement form, which is a little complicated to explain here, but if you google it there are good websites. The reason that 2's complement form is used versus simpler sign-magnitude are that it makes the math easier for a computer's processor.

The OS is responsible for interacting with hardware?
As we know that the OS is used to operate every device through the drivers present in the OS. So without the OS we cannot communicate with the devices (hardware). For every device some drivers are required to run them and these drives are provided by the operating system. So by this we can see that the OS provides the interface between the user and the hardware, as user does not make the device work he uses the OS.

You can also try downloading from the computer company web site and burn it to recovery media.

Three Types of Cameras Used in CCTV Systems?
CCTV security systems are one of the most preferred options, when it comes to efficient security systems. The facility of recording images is a very big factor in their popularity. They can act as a mechanical ‘witness’ to any crimes; CCTV footage is commonly accepted as evidence in many legal systems around the world. CCTV security systems can catch someone red-handed, so to say.
While people may know that CCTV means Closed Circuit Television, they may not be that aware about the different types of cameras used in CCTVSystems. We will briefly describe the three main types of cameras used in such systems below:
Analogue cameras:
Analogue cameras are the older type of cameras used in CCTV security systems. They convert the pictures they take to an analogue signal and send it to a storage device, like a video tape recorder, that can change the analogue signals back into pictures. The tape needs to be run at a very slow speed, for continuous recording. This ultimately results in images being a bit blurred, unless the subject stays relatively still. Analogue cameras can also be connected to a digital storage device, like a PC or a DVR (digital video recorder). However, the analogue signals need to be first converted into a digital signal through a video capture card. This compresses the images a bit.
Digital cameras:
These newer types of cameras are used in a lot of new CCTV systems. They are designed to be connected directly to digital storage device. As they convert images into digital signals, they do not need a video card. So even though images are still compressed, you can achieve near DVD picture quality with the footage from digital cameras. Compressing is done so that continuous recording can be done with a limited amount of storage space. Uncompressed pictures would rapidly take exhaust the available storage in many hard drives. One way of getting uncompressed images is to use a motion activated recording method.
There are also multi-megapixel cameras available on the market, which can capture images in resolutions as high as 11 mp. At such high resolutions, a lot of details, like license plates and faces, can be seen. These are slightly expensive though.
Network cameras:
These are either analogue or digital cameras that have an embedded video server that is capable of streaming videos directly to the web. They offer fairly better resolutions than ordinary analogue CCTV cameras. They are typically used as a cheap surveillance option, as they can cover a large area. Sometimes, only a single camera is used, along with some Ethernet cabling and a PC.
