Learn about different categories of computer systems that can be used to access information including handheld, fixed and shared devices. Based on the 2016 OCR Cambridge Technicals Level 3 IT specification for Unit 2 (Global Information). 1.3 - Access & Storage Devices Exam Board: OCR Specification: 2016 - Unit 2 Handheld Devices Examples of handheld devices: Handheld devices are small, light and possibly can be worn on the human body. These devices are very portable and easy to transport but their small size restricts the space for a powerful processor or high memory capacity. Handheld devices are becoming more powerful over time with extra features, storage options and network connectivity. Advantages: Light and portable so they can be easily carried on a person or in a pocket . Runs on battery power so do not need to be plugged into a power source (unless to charge) allowing for freedom of movement . Disadvantages: Low processing power due to small size and no cooling system . Relies on battery power which may not last for long. More likely to be lost, damaged or stolen . Generally small memory / storage capacity and low versatility . Smartphone Small Tablet eReader Smartwatch Portable Devices Examples of portable devices: Portable devices are larger and more powerful than handheld devices and can be carried easily in a bag. Laptops and larger tablets are the main examples of portable devices. Advantages: Light and portable so they can be easily transported in a laptop bag or small rucksack. Runs on battery power so they can work without a power outlet , such as to complete work on a train or in a library. More powerful and versatile than handheld devices. Disadvantages: Lower processing power and smaller memory / storage capacity than fixed devices like desktops. Reliant on their battery power which may only be a few hours. Laptop Large Tablet Fixed Devices Examples of fixed devices: Fixed devices are bulky devices that require a constant power connection . The most common example of a fixed device is a desktop computer which has a higher processing power and storage capacity than handheld and portable devices. Advantages: Desktop computers have the highest processing power of commercially available home / work computers and contain sufficient cooling systems to maintain temperature. Desktops and games consoles have large storage capacities and can be upgraded / expanded to even larger sizes. Desktop computers are very versatile and are powerful enough to be used for thousands of different purposes, from basic word processing and web browsing to server roles and data mining. Disadvantages: Reliant on a power outlet and cannot be transported whilst on. Heavy and difficult to move . May require additional components like a monitor. Typically more expensive than handheld and portable devices. Desktop Games Console Smart TV Shared Devices A shared device allows multiple users to access data at the same time . Cloud storage is the most common example of a shared device and is used by individuals, schools and businesses around the world through services such as Google Drive, Apple's iCloud and Microsoft's One Drive. A data centre is a dedicated building that contains computer systems - Facebook uses data centres across the globe so that their social media service can be available to users every second of the day. Database servers were explained in Unit 1 section 3.1 . Advantages: A ccessible by multiple users at the same time . For example, the database server can be accessed by employees of a bank simultaneously. Data centres allow online services to run all hours of the day and year . For example, Google uses data centres across the world to ensure their services can be accessed all of the time. Cloud storage frees up physical space for users as the storage is located (usually) on third-party servers. Cloud storage devices allow authorised users such as clients or staff members to access information or work remotely (outside of the office). Disadvantages: Shared devices are reliant on stable network connections . If a connection is lost, access to the device will be affected . Setting up shared devices within an organisation requires technical knowledge , especially for companies establishing their own cloud storage or data centre. Examples of shared devices: Cloud Storage Data Centre Database Server Q uesto's Q uestions 1.3 - Access & Storage Devices: 1. Identify the type of device that the following devices fit into: a.

An overview of what desktop publishing (DTP) is, considerations designer must take and common forms such as posters, leaflets and business cards. Desktop Publishing (DTP) What is DTP? Desktop Publishing (DTP) software allows people to create documents with a mixture of graphics and text . Examples of desktop publishing software are Microsoft Publisher and Serif PagePlus . Desktop publishers can be used to produce documents such as business cards, leaflets, brochures, newspapers, magazines and newsletters . DTP software can be cheap and printers at home are more common these days so people can design and print their own documents. Professional-looking documents can be made simply and without an extensive knowledge of graphic design. The biggest advantage of using DTP is that it is frame based . Text and picture frames can be laid out on the page, and rotated, moved or resized as necessary. It is easy to import images from clip art or the web. The view of the page is known as WYSIWYG (W hat Y ou S ee I s W hat Y ou G et) because the view on the computer will be very similar to what you get when it is printed. What to consider when using DTP Orientation Will your document be landscape or portrait ? Some document types are more commonly one orientation than the other. For example, business cards are generally landscape but newsletters are more often portrait. Size The size of a typical piece of paper is A4. But that is too large for most DTP documents. The larger the number, the smaller the piece of paper . A5 is half the size of A4 and A3 is twice the size of A4. Documents can also be measured in millimetres, for example, an appropriate business card size is 85mm wide and 55mm high. House Style A house style is a set of rules to ensure that each document made by a person or company is part of an identity . To be consistent , each document should use the same logo, titles, colours, graphics and layout . For example, the NHS always uses a blue colour, the same logo and similar layout on each of its documents. Some companies have perfected their house style so that they are synonymous with a single colour - e.g. McDonald's use yellow and Coca-Cola use red and white . DTP Documents Business Cards A business card is a small piece of card that must be simple and stylish . The purpose of a business card is to clearly state the contact details of a person or company. Sharing your business card with other people is one way to promote your business or skills to attract new business partners or customers. A business card must be uncluttered and clearly display relevant contact information, such as an email address, phone number or physical address. Today, business cards may also state social media contacts, such as Facebook pages or Twitter accounts. Flyers A flyer is a small handout that advertises an event or new product. The purpose of a flyer is to clearly and quickly promote an event . It must be eye-catching and to-the-point so that people can immediately understand what it is about. Flyers are often handed out in the street or posted through letterboxes so if it is not clear people will just ignore it. A flyer should use a large title to promote the event, as well as appropriate graphics and information about the date, location and time. It should also contain contact details including a telephone number, website and email address. Posters A poster is a large piece of paper that is put up to advertise an event and display more information than a flyer . Posters should promote an event by using large titles and graphics to clearly describe where the event is taking place, when it is and why people should go. Because there is much more space on a poster than a flyer, additional information can be added and some kind of persuasion to entice passers by to attend. Leaflets A leaflet is a small folded handout that provides more information about an event or new product. The purpose of a leaflet is to give additional details about an event . It can be used before an event to describe the different parts, such as the different acts in a circus or different bands at a festival. It can also be used during an event, such as at a school fair to list the different stalls. Because it is folded over it can display a large amount of information, with both text and graphics . The front of the leaflet should clearly display the purpose of it and the text inside must be readable with images to break up the words. There may also be contact information inside the leaflet, such as directions to a website or social media page .

Learn about application software installation methods, including clean, remote, cloud, mobile and network installation. Resources based on Unit F161 (Developing Application Software) for the OCR Cambridge Advanced Nationals in Computing (H029 / H129) AAQ (Alternative Academic Qualification). Qualification: Cambridge Advanced Nationals in Computing (AAQ) Certificate: Computing: Application Development (H029 / H129) Unit: F161: Developing Application Software Watch on YouTube: Application installation 5.2 - Application Software Installation You need to know how different installation processes (e.g. clean , remote , cloud , network and mobile installs) work as well as their advantages , disadvantages and appropriate uses . What You Need to Know Application Installation Application software can be installed using different methods depending on factors such as the number of devices , their location , network availability and the requirements of the users or organisation . Ghost / Image A ghost is a master copy (known as an image ) of a correctly configured system containing the required software and settings , which is created and deployed to other devices . This is used when the same applications and configuration need to be installed on many devices, such as computers in a school or business . It allows many devices to be configured quickly and consistently , reducing repetitive installation work and ensuring they have the same software and settings . However, creating and maintaining the image takes time , devices may need compatible hardware and an error or outdated application in the master image could be copied to every device . Upgrade An upgrade is when a newer version is installed over an existing version , usually retaining the user's existing data , settings and configuration . It is required when users need to move to a newer version of an application without completely reinstalling it . Upgrading is usually quicker and more convenient than a clean install and allows existing settings and data to be retained . But existing problems , unnecessary files or incompatible settings may remain and compatibility issues can occur between versions. Clean Install A clean install is when any previous installation is removed and a completely new copy of the application is installed . It is used when installing an application for the first time , or when an existing installation has serious problems and a fresh installation is required. A clean install provides a fresh installation without problems or unwanted settings from an older version, which can improve reliability . However, it can be more time-consuming and existing settings or application data may be lost if they are not backed up first . Repair/Modify Install A repair install (or modify install ) is when an existing installation is reopened to repair damaged or missing files . Installed features can be added or removed without completely reinstalling the application . This is used when an application is not functioning correctly or when its installed features need to be changed . It is usually quicker than completely reinstalling the application and can retain existing settings and data . But it may not fix more serious problems , and the required installation or repair files must be available . Remote Install A remote installation is when an administrator installs an application onto another device from a different location using remote management software . It is used when IT staff need to manage devices without physically accessing them, such as employee computers across different offices . A remote install saves time and travel , allows centralised management and can enable IT staff to install software on many geographically separated devices . However, it requires network connectivity , appropriate permissions and remote management tools . Connection problems could interrupt the installation. Unattended Install An unattended installation is automated using predefined settings , allowing it to complete without the user responding to installation prompts . It is used when installing the same application and settings on many devices or when installations need to occur without staff being present . Advantages are that it requires little or no user interaction , saves staff time and ensures consistent installation settings across devices. However, it requires careful configuration beforehand, and incorrect predefined settings could cause the same installation problem across multiple devices . Cloud Install With a cloud install , files are downloaded from an internet-based cloud service and then installed onto the device . It's suitable for when users or organisations need to download applications directly over the internet , particularly across different locations and devices . Cloud installs can be accessed from many locations and devices , it does not require physical installation media , can support automatic updates and may allow installations to be scheduled for convenient times . But it depends on a reliable internet connection , interrupted downloads can cause problems, large applications can use significant bandwidth and the device must meet the software's requirements . Mobile Install A mobile install is when an application is downloaded and installed through a mobile app store onto a smartphone or tablet . It's needed for applications designed for mobile devices , such as installing a revision app onto a student's tablet . It is usually simple and convenient for users as app stores can manage installation and updates . Also, applications can be installed directly onto the user's device . However, it requires sufficient storage and a compatible operating system and downloads can consume mobile data . Connectivity problems can interrupt installation and app stores may restrict what applications can be distributed . Network Install With a network install , files are stored in a central location on a local network and accessed by devices connected to that network . It is used when an organisation needs to install software on multiple devices connected to the same network , such as computers around a school . Advantages are that installation files can be managed centrally , physical installation media is not required for each device and many devices can access the same installation files . But it requires a working network connection , installing on many devices can increase network traffic and problems with the network or central server could prevent installations .

Learn about different types of utility software including firewall, anti-virus, defragmenter, compressor and backup software. Based on the 2016 OCR Cambridge Technicals Level 3 IT specification. 2.3: Utility Software Exam Board: OCR Specification: 2016 - Unit 1 What is utility software? Utility software are dedicated programs used for the maintenance and organisation of a computer system. Antivirus Software Antivirus software is used to locate and delete viruses on a computer system. The antivirus scans each file on the computer and compares it against a database of known viruses . Files with similar features to viruses in the database are identified and deleted . There are thousands of known viruses but new ones are created each day by attackers so antivirus software must be regularly updated to keep systems secure. Other roles of an antivirus: Checking all incoming and outgoing emails and their attachments . Checking files as they are downloaded . Scanning the hard drive for viruses and deleting them . Firewall A firewall manages incoming and outgoing network traffic . Each data packet is processed to check whether it should be given access to the network by examining the source and destination address . Unexpected data packets will be filtered out and not accepted to the network. Defragmentation As files are edited over time they will become fragmented - this is when the file is split into parts that are stored in different locations on the hard disk drive . Files that are fragmented take longer to load and read because of the distance between the fragments of the file. Defragmentation software is used to rearrange the file on the hard disk drive so that all parts are together again in order. Defragmentation improves the speed of accessing data on the hard disk drive. Compression Compression is used to decrease the size of a file . This is beneficial as more files can be stored on a storage device if the size has been reduced. Compressed files can be transferred faster across a network because they are smaller in size . Monitors, Managers & Cleaners Other roles of a firewall include: Blocking access to insecure / malicious web sites . Blocking certain programs from accessing the internet . Blocking unexpected / unauthorised downloads . Preventing specific users on a network accessing certain files . Monitoring network ports . System monitors check the resources of a computer and display how much CPU time and memory current applications are using. Task managers allow a user to close processes and applications if they have stopped responding or if one is using too many resources. Press Ctrl + Alt + Delete on any Windows computer to open Windows Task Manager which is a system monitor and task manager tool. A disk cleaner is used to scan a hard disk drive and remove unused files . This is used to free up space on the hard drive. A disk scanner will scan a hard disc for any errors and attempt to repair them . Backing Up Data A backup is a copy of data that can be used if the original data is corrupted or lost . Backups of all data should be made regularly and stored in an alternative location . Alternatively, imaging (also known as disk cloning ) creates an identical image of a storage drive to be stored in a different location . Q uesto's Q uestions 2.3 - Utility Software: 1.

Learn about how sounds are represented in a computer system including how analogue sound waves are converted into binary. Also, learn about sample rate, bit depth, bit rate and metadata. Based on the J277 OCR GCSE Computer Science specification (first taught from 2020 onwards). 2.4e: Sound Storage Exam Board: OCR Specification: J277 Watch on YouTube : Sample Rate Bit Depth Sound File Size Converting Analogue Sound to Binary Analogue sound waves must be digitally recorded and stored in binary . To record the sound, the amplitude (height ) of the analogue sound wave is measured and recorded in binary at specific intervals . 0010 1011 0101 0101 Analog sound wave ADC (Analog to Digital Converter) Binary sample Sampling an Analogue Sound Wave Digital sampling is discrete (separate) and not continuous like analogue waves. To get the highest quality sound, many samples are taken to recreate the analogue wave as closely as possible . Sample Rate The sample rate (sampling frequency) is the number of times per second the amplitude of the sound wave is measured . It is measured in kilohertz (kHz), for example CD quality is 44.1kHz (44,100 samples per second). The higher the sample rate , the better the audio quality as the digital data more closely resembles an analogue wave . However, higher sample rates result in larger file sizes because more data is stored for each individual sample. A low sample rate will result in a low-quality sound because the digital data does not closely resemble the original analog wave . A higher sample rate will result in a higher-quality sound because the digital data more closely resembles the original analog wave . Bit Depth The bit depth is the number of bits available to represent each sample . For example, a sample with a bit depth of 4 could be 0101 or 0111 or 1010. A sample with a bit depth of 8 could be 01010110 or 1010110 or 11001111. A common bit depth is 16 bits . The higher the bit depth , the more bits are available to be used for each sample. Therefore the quality is often higher as the wave more closely resembles an analog wave . The file size will also be larger if the bit depth is higher, as each sample stores additional bits . low bit rate = lower quality high bit rate = higher quality sound file size = sample rate x bit depth x duration Example: A short audio sample has a bit depth of 4 and a sample rate of 10 samples per second . The clip is 15 seconds long . 4 bits x 10 = 40 bits per second. 40 x 15 = 600 bits . To convert the answer from bits to bytes , divide by 8 . 600 bits ÷ 8 = 75 bytes .
