The are a large amount of ports for the user to connect to. The PS/2 ports on the system allow for keyboaerd and mouse functionality to be availible. The optional CD-ROM and floppy disk drive aloow the user to decide how memory is used on the device. There is also a internal and external compact flash slot.
The Bosch BNO055 IMU sensors come with the software package that consists of sensor drivers. In order to let the sensors to give data, these drivers should be added in the Arduino software library folder inside the computer. The driver is capable of giving the raw sensor data by using the sensor library in the Arduino code. The Arduino library used for this purpose was ‘Wire Library’, which allow communication with I^2 C devices. This library can be manually downloaded and added to the Arduino folder.
In 4th chapter I learned about CPU and other aspects related to it such as RISC and CISC.CPU stands for central processing unit and it is very suitable name for it as it processes the instructions that it gathers from files. Following diagrams explain the basic architecture of CPU: CPU performance is given by the fundamental law: Thus, CPU performance is dependent upon Instruction Count, CPI (Cycles per instruction) and Clock cycle time. And all three are affected by the instruction set architecture. Instruction Count CPI Clock Program x Compiler x x Instruction Set Architecture x x x Microarchitecture x x Physical Design x This underlines the importance of the instruction set architecture. There are two prevalent
However, this computer does connect to an external TV tuner over ethernet to record over-the-air signals. As indicated in the bulleted list above, the 250GB SATA drive is configured as the boot device, while the two 1TB drives are configured to store all important data, recordings, and DVD to MPEG compatible conversions. Although the 250GB drive is specified as a boot device in the BIOS, it is third in the boot order following USB boot devices, and CDROMs. This BIOS boot setting is configured to allow for an alternate boot up source, should the main boot drive fail, which is the current case. Since this computer is configured as an HTPC, all other BIOS settings provide no advantage and are set to

Unit: 9/ P1 1. Various Network Topologies: Star: Star topology is used to connect all computers to a central switch, which is responsible for forwarding the data to its destination computers. As shows in the diagram below: This type of topology is used with Ethernet and frame relay. Ring: Rings topology is used to connect all computers together in one single ring but if one computer Failed the whole network will fail. As shows in the diagram below: This method of topology is used by token ring and EAPS (Ethernet automatic protection system).
As described in the specifications, a thin computer comes with graphics and audio card (built-in), CPU, RAM, Hard drive, network card and some expansion slots such as USB slots to connect a mouse and a keyboard. Due to its hardware restrictions/limitations, these machines run their mapped Operating Systems and application from the Application server on the network.

Both types of networks provide network services using operating systems that can communicate with each other through common protocols. Each of these networks enables control of how users and programs get access to resources. Also, clients in a client server network and nodes or hosts in a peer-to-peer network use any combination of desktop, mobile, or tablet operating systems. 2. Discuss the difference between a physical topology and a logical topology.
14. What are the two general approaches operating system take to allow processes to communicate with each other (to allow inter process communication or IPC)? Answer: The shared memory system and message passing are the two general Operating system that take to allow processes to communicate with each other. 15. Name the two types of pipes an operating system can offer for IPC.
Workstations are special computers designed or technical applications and its meant to be used at one at a time how it works is that it is connected to a local area network (LAN) which is able to run multi user operating system. In terms of computer networks a server is a computer program that provides services to other computer programs which is sent to their users in the same time. Example of a work station: An example, of a server is print server is an
These receivers have a typical hysteresis of 0.5 V and a typical threshold of 1.3 V. Figure 4.16: Pin Diagram of MAX232 4.13 RS232 Interface In telecommunications, RS-232 is the traditional name for a series of standards for serial binary single-ended data and control signals connecting between a DCE (Data Circuit-terminating Equipment) and a DTE (Data Terminal Equipment). It is use to connect the computer serial port to the electronics component like data storage, printers, mice, un-interruptible power supplies, and other peripheral devices. The standard defines the meaning of signals, the electrical characteristics and timing of signals, and pin out of connectors and the physical size. Figure 4.17: RS232 4.14 Motor
