1The six hardware components of a computer system are:
[blank_start]Central processing Unit[blank_end] - the actual hardware that interprets and executes the program (software) instructions and coordinates how all the other hardware devices work together.
[blank_start]Primary Storage[blank_end] - the computer’s main memory, which consists of the random access memory (RAM), the cache memory and the read-only memory (ROM) that is directly accessible to the CPU.
[blank_start]Secondary Storage[blank_end] - equipment designed to store large volumes of data for long-term storage
[blank_start]Input Devices[blank_end] - equipment used to capture information and commands
[blank_start]Output Devices[blank_end] - equipment used to see, hear or otherwise convey the results of information processing requests to users.
[blank_start]Communication Devices[blank_end] - equipment used to send information and receive it from one location to another- ACentral processing Unit
- BPrimary Storage
- CSecondary Storage
- DInput Devices
- EOutput Devices
- FCommunication Devices
2Primary storage
- Aequipment used to send information and receive it from one location to another (e.g. modem).
- Bthe computer’s main memory, which consists of the random access memory (RAM), the cache memory and the read-only memory (ROM) that is directly accessible to the CPU.
- Cequipment used to see, hear or otherwise convey the results of information processing requests (e.g. monitor, printer) to users.
3Central processing unit (CPU)
- Athe actual hardware that interprets and executes the program (software) instructions and coordinates how all the other hardware devices work together.
- Bthe cache memory and the read-only memory (ROM) that is directly accessible to the CPU.
- Cequipment used to capture information and commands (e.g. keyboard, scanner). Output devices—equipment used to see, hear or otherwise convey the results of information processing requests (e.g. monitor, printer) to users.
4A CPU contains two primary parts: a [blank_start]control[blank_end] unit and an [blank_start]arithmetic-logic[blank_end] unit
- Acontrol
- Barithmetic-logic
5CPU speed is usually quoted in [blank_start]megahertz[blank_end] and [blank_start]gigahertz[blank_end].
- Amegahertz
- Bgigahertz
6gigahertz
- Athe number of billions of CPU cycles per second
- Bthe number of millions of CPU cycles per second
7the number of millions of CPU cycles per second
- AMegahertz
- BGigahertz
8Primary storage is the computer’s main memory, which consists of [blank_start]random access memory[blank_end] (RAM) [blank_start]cache[blank_end] memory and [blank_start]read-only[blank_end] memory (ROM) that is directly accessible to the CPU.
- Arandom access memory
- Bcache
- Cread-only
9Give an example of an output device. [blank_start]Printer[blank_end] or [blank_start]monitor[blank_end]
- APrinter
- Bmonitor
10Give an example of secondary storage. [blank_start]hard drive[blank_end], [blank_start]memory card[blank_end], [blank_start]USB drive[blank_end]
- Amemory card
- BUSB drive
- Chard drive
11[blank_start]Output device[blank_end] equipment used to see, hear or otherwise accept the results of information processing requests and to convey those results to users
- AOutput device
12[blank_start]Input device[blank_end] equipment used to capture information and commands.
- AInput device
13The two types of software are [blank_start]system[blank_end] software and [blank_start]application[blank_end] software.
- Asystem
- Bapplication
14[blank_start]System software[blank_end] controls how the various input and output devices work together along with the application software
- ASystem software
15[blank_start]Application[blank_end] software used for specific information processing needs, including payroll, customer relationship management, project management, training and many others
- AApplication
16A network typically includes the following hardware components (besides the computers themselves):
[blank_start]network interface card (NIC)[blank_end]—a card inside the computer that lets it send and receive messages from other computers. Every NIC has a unique hardware address, known as its MAC address, which is used to identify devices on the network
[blank_start]hub (switch or router)[blank_end]—hardware to perform traffic control in the distribution of the network signals (requests and transmissions). A router is the name given for a switch that is used for Internet traffic
[blank_start]modem[blank_end]—required for internet connection for the transmission and receipt of data. Historically, a dial-up modem was used to connect via telephone lines: now a cable or ADSL modem is used
[blank_start]transmission media[blank_end]—provide the means for data to be streamed from one device to another; generally classified as wired (twisted pair copper cable, coaxial cable, optical fibre) or wireless (radio waves, infra-red light waves, ultra-sonic waves electro-magnetic induction).
Networks are differentiated by the following:
[blank_start]topology[blank_end]—the arrangement of the cabling/traffic of devices on the network (e.g. point-to-point, liner, bus, star, ring, tree, mesh, hybrid)
[blank_start]architecture[blank_end]—the design of the computer network—the computers and their functional organisation and configuration. It is based on the Open Systems Interconnection model, or OSI (resulting in, for example, peer-to-peer, client/server)
[blank_start]protocols[blank_end]—provide the foundation for communication between computers; there are a set of rules and conventions between network devices (e.g. ethernet, transmission control protocol/Internet protocol (TCP/IP), File Transfer Protocol (FTP), Hyper Text Transfer Protocol (HTTP))
[blank_start]transmission media[blank_end].- Anetwork interface card (NIC)
- Bhub (switch or router)
- Cmodem
- Dtransmission media

17Today’s corporate digital networks include a combination of different types of networks, which can be wired or wireless. These are: [blank_start]local area networks[blank_end] (LANs) [blank_start]wide area networks[blank_end] (WANs) [blank_start]metropolitan area networks[blank_end] (MANs).
- Alocal area networks
- Bwide area networks
- Cmetropolitan area networks
18While LANs, WANs and MANs all provide users with an accessible and reliable network infrastructure, they differ in many dimensions: two of the most important are [blank_start]cost[blank_end] and [blank_start]performance[blank_end].
- Acost
- Bperformance
19[blank_start]LAN[blank_end] a computer network designed to connect a group of computers in close proximity to each other such as in an office building, a school or a home
